The box of bouillon cubes is wedged behind the oatmeal, the corners soft and the date long gone. Maybe the jar of paste has been open since last winter. Soup is on tonight’s menu, and you wonder if any of it is still worth using. Bouillon lasts a long time, but not forever, and the answer changes between cubes, granules and paste. Here is what extension and brand guidance says, and what to do with the broth you make from it.
Does bouillon go bad?
For a complete pantry and fridge reference, see our Food Storage Guide. For whether each type needs the refrigerator, see whether bouillon needs to be refrigerated. For other pantry flavor makers, see whether spices go bad. Broth you make from bouillon follows the same cold-storage rules as chicken broth, beef broth, vegetable broth and bone broth.
đź“‹ Bouillon Shelf Life: At a Glance
| Cubes or granules, before use | Kansas State Extension: 2 years at 70°F kept dry and covered, with no opened or unopened split. Maggi: 24 months for cubes, 21 for granulated. Follow the date |
| Opened cubes or granules | No agency time. Herb-Ox says to use by the expiration date and that opened granules need no refrigeration. Keep them sealed, dry and cool |
| Unopened paste or base | Better Than Bouillon: 2 years from manufacture. Follow the Best By date |
| Opened paste or base | Better Than Bouillon says to refrigerate and to discard jars that weren’t. Other pastes may differ, so follow the label. Knorr’s guide says paste stays fresh in the refrigerator up to a year |
| Dissolved bouillon (broth) | 3 to 4 days at 40°F or below as a conservative default. 2 hours at room temperature at most, 1 hour above 90°F |
| Storage spot | Cool, dry and dark, away from the stove and sun |
| Mold, off smell or damp, sticky bouillon | Discard it |
Key Takeaways
- Kansas State Extension’s guide to safe cupboard storage, revised June 2026, lists bouillon cubes or granules at 2 years, based on storage at 70°F, with the note keep dry and covered. It doesn’t separate opened from unopened.
- Maggi’s FAQ lists 24 months for its cubes, 21 months for tablets and granulated products, and 18 months for tomato-based bouillon. Asked whether its products need to be refrigerated or frozen, it answers that all of its products are shelf stable.
- Better Than Bouillon’s FAQ gives its pastes a 2 year shelf life from the manufacturing date. It says to refrigerate after opening, not to freeze, and to discard jars that weren’t refrigerated or that are past the Best By date. Other pastes may differ.
- Knorr’s FAQ says its products carry a Best If Used By date for optimum quality and freshness, and to store them in a cool, dry place. Herb-Ox’s FAQ says its bouillon should be used by the expiration date and doesn’t require refrigeration after opening, but needs it once prepared.
- The USDA charts we checked don’t include a separate entry for reconstituted bouillon. Its Keep Food Safe chart lists soups and stews at 3 to 4 days in the refrigerator, and it says to refrigerate perishable food within 2 hours, or 1 hour above 90°F.
- Brand time limits are product-specific manufacturer directions, not USDA recommendations. Check the package in your hand.
Bouillon is a dried or concentrated form of broth, sold as cubes, granules or a paste. Knorr’s guide describes it as a dehydrated stock sold in cubes, granulated forms and pastes. Concentrates and bases sold as liquids are different products with their own labels, and so are ready-to-drink cartons, which we cover in our chicken broth refrigeration guide. If you also keep dried noodles in the pantry, see whether ramen goes bad.
How Long Does Bouillon Last?
Cubes and granules are dried, while pastes are concentrated bases. Dry cubes and granules are listed at about two years, and some pastes list two years from manufacture and then need the refrigerator. Kansas State University Extension’s guide to safe cupboard storage, revised June 2026, lists bouillon cubes or granules at 2 years, with the note keep dry and covered. Its times are for storage at 70°F, and the guide doesn’t separate opened from unopened packages. Maggi’s FAQ lists cubes at 24 months, tablets and granulated products at 21 months, and tomato-based bouillon at 18 months. It tells readers to check the expiration date on the package because it varies from product to product, and it says its storage information is for the product before use. Better Than Bouillon’s FAQ gives its pastes a shelf life of two years from the date of manufacture. Knorr’s FAQ says every package carries a Best If Used By date that assures optimum quality and freshness, and gives no length of time.
| Type of bouillon | Our suggested guideline | What the sources say |
|---|---|---|
| Unopened cubes | Follow the date on the package, and keep them dry | Kansas State Extension: 2 years at 70°F kept dry and covered, with no opened or unopened split. Maggi lists cubes at 24 months for the product before use |
| Unopened granules or powder | Follow the date on the package, and keep the container sealed | Kansas State Extension: cubes or granules 2 years, with no opened or unopened split. Maggi: tablets and granulated 21 months |
| Opened cubes or granules | Use by the printed date, kept sealed in a cool, dry spot | No agency time. Herb-Ox: use by the expiration date, no refrigeration needed after opening. Knorr’s guide: move unused cubes to an airtight container or resealable bag |
| Unopened paste or base | Follow the Best By date | Better Than Bouillon: 2 years from manufacture |
| Opened paste or base | Refrigerate it, and follow the label | Better Than Bouillon: refrigerate after opening. Other pastes may differ. Knorr’s guide: paste stays fresh in the refrigerator up to a year |
| Dissolved bouillon (broth) | 3 to 4 days at 40°F or below | USDA soups and stews and leftovers: 3 to 4 days. The charts we checked have no separate entry for reconstituted bouillon |
| Left out on the counter | 2 hours at most, 1 hour above 90°F | USDA: perishable food left out longer should be thrown away |
These timings assume the bouillon stayed dry, sealed and out of heat. The two-year figures are for quality and storage, and they don’t promise anything about a particular package. The 3 to 4 days for dissolved bouillon is our own conservative application of USDA’s general figures. A date on a package is the manufacturer’s direction for that product, so follow it when it gives one.
Do Bouillon Cubes Go Bad?
Slowly. Cubes are dried, so age and moisture are the main concerns. Knorr’s bouillon guide says bouillon cubes can expire and that their flavor may diminish over time, and it advises checking the expiration date. Maggi lists its cubes at 24 months. Kansas State Extension lists cubes or granules at 2 years kept dry and covered. Their main enemy is moisture, so the foil wrapper and a closed box matter. Knorr’s guide suggests moving unused cubes into an airtight container or resealable bag once the package is open. We’d also keep them out of the steam above the stove, which is our own suggestion.
Does Bouillon Powder or Granules Go Bad?
They keep about as long as cubes, on the same terms. Kansas State Extension groups cubes and granules at 2 years kept dry and covered, and Maggi lists tablets and granulated products at 21 months. Knorr’s guide says granulated bouillon typically comes in a resealable container designed to protect it from moisture, so close it firmly after each use. A dry spoon helps too, which is our own tip. We found no agency guidance on how long opened granules last. Herb-Ox’s FAQ says its bouillon should be used by the expiration date and that it doesn’t require refrigeration after opening, so the printed date is your guide.
Does Bouillon Paste or Base Go Bad?
Yes, and many pastes need the refrigerator once opened. Better Than Bouillon’s FAQ says the product should be refrigerated after opening, and that jars not put in the refrigerator after opening should be discarded because the company can’t vouch for their quality or performance. It also says not to freeze the product, and that opened jars past the Best By date should be discarded. Its 2 year shelf life starts from the date of manufacture, not the day you open it. The FAQ gives its refrigeration rule for after opening and says nothing on where to keep unopened jars, so follow the label and the Best By date. Knorr’s guide says an opened bouillon paste stays fresh in the refrigerator for up to a year, though that is a general statement in a cooking guide and not a label direction. Other pastes and bases may differ, so follow the label of the one you own.
Better Than Bouillon’s FAQ also says the product does get darker as it is stored, which it calls perfectly normal and safe to consume if used before the Best By date. It says small particles of ingredients are expected too. Its FAQ adds that the bases aren’t ready to eat and must be dissolved in warm or boiling water or cooked. The FAQ also says the Best By date is printed on top of the lid, and that for its U.S. products it is formatted Day/Month/Year. A lid reading 04/05/2027 would therefore mean 4 May 2027, which is our own worked example.
Can You Use Bouillon After the Expiration Date?
It depends on the type and on what the package says. USDA’s Shelf-Stable Food Safety page says dating is for quality, not safety. USDA doesn’t mention bouillon on that page, so that is a general statement about shelf-stable food and not a bouillon ruling. Knorr describes its date as the point of optimum quality and freshness and recommends using the product by then. Better Than Bouillon, speaking for its own products, advises discarding any product past its Best By date, since it can’t vouch for performance. For dry cubes or granules that have stayed sealed and dry, we’d treat the date as a quality marker and inspect them closely, which is our own judgment. Normal looks and smell don’t show that bouillon is safe, because USDA says you can’t see, smell, or taste harmful bacteria that may cause illness. For a jar of refrigerated paste past its date, or one that sat out unrefrigerated, we’d follow the brand and discard it.
How Long Does Dissolved Bouillon Last?
Treat it like homemade broth. Once bouillon is dissolved in water, it is a perishable food. The USDA charts we checked don’t include a separate entry for reconstituted bouillon. Its Keep Food Safe cold storage chart lists soups and stews, and gravy and meat broth, at 3 to 4 days in the refrigerator and 2 to 3 months in the freezer. It also says to refrigerate perishable food within 2 hours, or 1 hour when the air is above 90°F. Maggi’s FAQ says it can’t recommend storage times for prepared broth because refrigerator and freezer conditions vary. Herb-Ox’s FAQ says its bouillon needs to be refrigerated once prepared, with no number of days. So 3 to 4 days at 40°F or below is our conservative default, applying USDA’s general figures for soups and stews to any flavor of bouillon.
Only make as much as you need, which is our own tip. If you have extra, cool it in shallow containers and refrigerate it. USDA’s leftovers guidance says hot food can go directly into the refrigerator or into an ice or cold water bath first, and to reheat soups to a rolling boil. The 2 hours counts time food spends at room temperature, and food held hot at 140°F or warmer is a separate case. For more on what broth does in the refrigerator, see our guides to chicken broth and bone broth.
How Should You Store Bouillon?
Cool, dry and dark. Kansas State Extension says to store foods in a cool, dry, dark location away from heat sources like appliances and the sun. Maggi’s FAQ recommends a cool, dry, dark pantry, and Knorr says to store its products in a cool, dry place. USDA’s shelf-stable page, which covers canned foods and other shelf-stable products, says temperatures below 85°F are best and not to store them above or beside the stove. We apply the same logic to bouillon, which is our own reading. Keep cubes and granules closed so moisture stays out. Keep paste in the refrigerator after opening, as the brand directs.
Asked whether its products need refrigeration or freezing, Maggi’s FAQ answers that all of its products are shelf stable. That is why dry bouillon is a pantry item, while pastes and bases may require refrigeration, so follow the label.
How Can You Tell if Bouillon Is Bad?
Look for mold, a sour, musty or off smell, or cubes and granules that look damp, sticky or show moisture damage. Bugs or webbing in the box are also a reason to throw it out. Moisture damage is our own checklist item, because moisture is what Kansas State Extension’s note, keep dry and covered, is meant to prevent. USDA’s mold guidance says not to sniff a moldy item because it can cause respiratory trouble. We don’t suggest tasting bouillon to check it. A paste that was left unrefrigerated after opening, or that is past its Best By date, is discarded by the brand’s own advice.
Weaker flavor from age is a quality matter, according to Knorr. Don’t treat darkening in a refrigerated paste as spoilage by itself, because Better Than Bouillon calls that normal. Neither is a safety test, so go by the dates and the storage history.
What Can You Make With Bouillon Before It Goes Bad?
Soup is the easiest use. We have red lentil soup, tortilla soup, clam corn chowder, cauliflower soup with scallops and New Orleans seafood gumbo. Check each recipe for the type and amount of broth it calls for, since bouillon is concentrated and may not swap one for one. Bouillon is also salty, so recipes that call for it may need less added salt, which is our own tip, and you’ll find more soup pointers in our guide to common soup mistakes. For gravy made with bouillon, see whether gravy goes bad. If a soup comes out thin, see how to thicken soup without cream.
Signs Something Is Wrong
- Visible mold on cubes, granules or paste. USDA says not to sniff a moldy item because it can cause respiratory trouble. Discard it.
- A sour, musty or rancid smell. This is our own checklist, not an agency list.
- Cubes or granules that are damp, sticky or show moisture damage. Moisture is what Kansas State Extension’s keep dry and covered note guards against. This is also our own checklist.
- Bugs or webbing in the box or jar. This is our own checklist too.
- An opened jar of paste that was not refrigerated. Better Than Bouillon says to discard it.
- Better Than Bouillon paste past its Best By date. The brand advises discarding it, since it can’t vouch for performance.
- Dissolved bouillon left out more than 2 hours (1 hour above 90°F). Throw it out, even if it looks fine.
- Dissolved bouillon older than 3 to 4 days. This is our default when the package gives no other time.
We don’t suggest tasting bouillon or broth to test it. USDA says you can’t see, smell, or taste harmful bacteria that may cause illness, so go by the dates and the storage history.
Things That Don’t Automatically Mean Trouble
- A refrigerated paste that has darkened. Better Than Bouillon calls this normal if the product is used before the Best By date.
- Small particles that don’t dissolve in paste. The brand says these are expected.
- No pop when you open a jar of paste. Better Than Bouillon says it doesn’t vacuum-seal its products, though an intact outside safety seal and an unexpired Best By date are what it points to.
- Dry cubes or granules that have lost some strength with age. Knorr describes this as a quality matter.
These are quality observations, not safety tests. Dates and storage matter more.
Quick Storage Reference
- Cubes or granules before use: Cool, dry and dark, to the date. Kansas State Extension lists 2 years at 70°F.
- Opened cubes or granules: Closed tight or in an airtight container, still dry. Use by the date.
- Unopened paste or base: Follow the jar’s label, to the Best By date. 2 years from manufacture for Better Than Bouillon.
- Opened paste or base: Refrigerate. Don’t freeze Better Than Bouillon.
- Dissolved bouillon: Refrigerate within 2 hours, at 40°F or below. 3 to 4 days.
- Counter: 2 hours at most for dissolved bouillon, 1 hour above 90°F.
| Situation | What to Do |
|---|---|
| Box of cubes, 6 months past the printed date, kept dry in the pantry | Check the package for the brand’s date guidance first. Knorr treats its date as a quality marker. Throw it out if the box is damp or the cubes show mold, bugs or an off smell. A normal look doesn’t establish safety, so when in doubt, discard it. |
| Open box of cubes that sat beside the stove, now sticky and clumped | Discard it. Moisture and heat are what dry storage is meant to prevent, which is our own judgment. |
| Jar of bouillon paste, opened 3 months ago and refrigerated, before its Best By date | Generally fine to use if refrigerated promptly, kept at 40°F or below, and free of mold, damage or off smell. The Better Than Bouillon rule is to refrigerate after opening and use by the Best By date. |
| Jar of bouillon paste, opened and left in the pantry for a week | Discard it. Better Than Bouillon says jars not refrigerated after opening should be discarded. |
| Jar of paste, one month past its Best By date, refrigerated the whole time | Better Than Bouillon advises discarding product past its Best By date. For other brands, follow the label. |
| Dissolved bouillon, 2 days in the refrigerator | Generally fine to use if it was refrigerated promptly, kept at 40°F or below, and shows no mold or off smell. It is within our 3 to 4 day default. |
| Dissolved bouillon, 6 days in the refrigerator | Discard it. That is past the 3 to 4 day default. |
| Pot of bouillon broth left on the stove overnight | Discard it. USDA says perishable food left out more than 2 hours should be thrown away. |
In November 2026 we read Kansas State University Extension’s guide to safe cupboard storage (MF3131, revised June 2026). We read USDA’s Shelf-Stable Food Safety page, its Keep Food Safe page and cold storage chart, its leftovers guidance and its Molds on Food page. We read the FAQ pages of Better Than Bouillon, Maggi, Knorr and Herb-Ox, and Knorr’s bouillon guide. Kansas State Extension’s guide doesn’t separate opened from unopened bouillon and has no entry for paste. The USDA charts we checked don’t include a separate entry for reconstituted bouillon, so for dissolved bouillon we use its soup, meat broth and leftover figures and say so. Brand times are manufacturer directions for those products. The 3 to 4 day default, the storage and handling tips and the spoilage checklist are our own judgment. Brand pages change, so follow the package in your hand along with safe handling and temperature limits. Our own suggestions say we’d or we suggest. This article is general information, not medical advice.
Does Bouillon Go Bad FAQ
Does bouillon go bad?
Yes, but slowly. Kansas State Extension lists cubes or granules at 2 years kept dry and covered, and brands print their own dates. Many pastes need the refrigerator after opening, and dissolved bouillon is a perishable broth.
Do bouillon cubes go bad?
They can. Maggi lists its cubes at 24 months, Kansas State Extension lists cubes or granules at 2 years, and Knorr says cubes can expire and lose flavor over time. Keep them dry, since moisture is the main threat.
How long do bouillon cubes last?
Kansas State Extension lists 2 years at 70°F kept dry and covered, without separating opened from unopened. Maggi lists 24 months for cubes for the product before use. Use the date printed on your package, and keep opened cubes sealed and dry, since we found no agency time for them.
How long do bouillon cubes last after opening?
We found no agency or brand time for opened cubes. Kansas State Extension doesn’t separate opened from unopened, and Herb-Ox’s FAQ says its bouillon should be used by the expiration date and doesn’t require refrigeration after opening. Knorr’s guide says to move unused cubes into an airtight container or resealable bag. Check them for dampness, mold or off smells before each use.
How long does bouillon powder or granulated bouillon last?
Kansas State Extension groups cubes and granules at 2 years kept dry and covered. Maggi lists tablets and granulated products at 21 months. Check the date on your container.
Does bouillon paste go bad?
Yes. Better Than Bouillon gives a 2 year shelf life from manufacture and says to refrigerate after opening. It says jars that weren’t refrigerated should be discarded, and so should jars past the Best By date. Other brands may differ.
Does Better Than Bouillon need to be refrigerated?
After opening, yes, according to its FAQ. The brand says not to freeze it either. Its FAQ gives the refrigeration rule for after opening and doesn’t say where to keep unopened jars, so follow the jar’s label and the Best By date.
How long does Better Than Bouillon last after opening?
Its FAQ gives no number of months after opening. It says to refrigerate after opening and to discard jars past the Best By date, which is 2 years from the manufacturing date. Knorr’s guide says an opened bouillon paste stays fresh in the refrigerator for up to a year, but that is a different brand.
How do you read the Better Than Bouillon date?
Better Than Bouillon’s FAQ says the Best By date is printed on top of the lid. For its U.S. products the date is formatted Day/Month/Year, and for Canada-labeled products it is Year/Month/Day. So 04/05/2027 on a U.S. jar would mean 4 May 2027. The brand advises discarding jars past that date.
Why did my Better Than Bouillon get darker?
Better Than Bouillon’s FAQ says the product does get darker when it is stored. It calls this perfectly normal and safe to consume as long as it is used before the Best By date.
Can you use bouillon after the expiration date?
For dry cubes and granules that are still dry, sealed and free of mold, the date is mainly a quality marker, which matches Knorr’s wording and USDA’s general statement that dating is for quality. Better Than Bouillon advises discarding its paste past the Best By date. Normal looks and smell don’t show it is safe, so when in doubt, follow the brand.
How long does dissolved bouillon last in the fridge?
The USDA charts we checked don’t include a separate entry for reconstituted bouillon. We use 3 to 4 days at 40°F or below as a conservative default for any flavor, based on USDA’s soups and stews and leftovers figures.
How long can bouillon broth sit out?
Perishable broth shouldn’t sit at room temperature more than 2 hours, or 1 hour when the air is above 90°F, per USDA. After that, discard it.
Can you freeze bouillon cubes?
We found no agency guidance for freezing dry cubes. Knorr’s FAQ recommends storing its products as described on the package, and Maggi’s FAQ says all of its products are shelf stable. Better Than Bouillon says not to freeze its product.
Can you freeze broth made from bouillon?
USDA’s Keep Food Safe chart lists soups and stews, and gravy and meat broth, at 2 to 3 months in the freezer. Broth made from bouillon isn’t a separate entry in the charts we checked, so we’d apply those figures, which is our own reading. FoodSafety.gov’s Cold Food Storage Chart says its freezer guidelines are for quality only, so treat 2 to 3 months as a quality guideline. Cool it first and use a freezer-safe container, which is our own tip.
Do opened bouillon cubes or granules need to be refrigerated?
Not according to the brands we read. Herb-Ox’s FAQ says its bouillon doesn’t require refrigeration after opening and should be used by the expiration date, and Maggi says all of its products are shelf stable. Keep the package closed in a cool, dry spot. Pastes and bases may require refrigeration, as Better Than Bouillon does after opening, so follow the label.
Are white spots on bouillon cubes mold?
We found no agency or brand source that explains white specks on cubes. Visible mold is a reason to discard it, and USDA says not to sniff a moldy item. If you can’t tell what you’re seeing, or the cubes are also damp or smell off, we’d discard them, which is our own judgment.
Should you refrigerate bouillon cubes?
Maggi’s FAQ answers that all of its products are shelf stable, and Knorr says to store its products in a cool, dry place. Keep cubes cool, dry and dark in a closed container. Many pastes need refrigeration after opening, so follow the label.
Where should you store bouillon?
In a cool, dry, dark place. Kansas State Extension says to store foods away from heat sources like appliances and the sun, and Maggi recommends a cool, dry, dark pantry. Close the package firmly after each use.
How can you tell if bouillon cubes are bad?
Mold, a sour or musty smell, or cubes that look damp, sticky or show moisture damage. Bugs or webbing are also a reason to throw it out. These are our own checklist items. We don’t suggest tasting them.
Why are my bouillon cubes hard or crumbly?
We found no source that explains it. Moisture is the usual concern for dry bouillon, and Kansas State Extension says to keep it dry and covered. If the cubes are damp, sticky or moldy, discard them. A dry, crumbly cube is a quality question, which is our own reading.
Is bouillon safe to eat straight from the package?
Better Than Bouillon says its bases are not ready to eat and must be dissolved in warm or boiling water or cooked. For cubes and granules, follow the package directions.
What is the difference between bouillon cubes, granules and paste for storage?
Cubes and granules are dried and keep in a cool, dry pantry. Paste is a moist, concentrated base and, for Better Than Bouillon, must be refrigerated after opening. Follow the label for your brand.
Does bouillon go bad faster than stock or broth?
Dry bouillon is a pantry item, while broth that is opened from a carton or made in a pot is perishable and has a short refrigerator life. Unopened cartons are shelf stable too. Once dissolved, bouillon is a perishable food like any broth.
Do bouillon cubes expire?
They carry dates. Knorr says its date marks optimum quality and freshness, and Maggi lists times by product. Kansas State Extension lists cubes or granules at 2 years.
Do chicken, beef and vegetable bouillon have different shelf lives?
The sources we read mostly don’t split them by flavor. Kansas State Extension lists bouillon cubes or granules as one category, and Maggi lists cubes at 24 months, tablets and granulated products at 21 months and tomato-based bouillon at 18 months. Check the printed date on your own package.
Can old bouillon make you sick?
A printed date alone doesn’t tell you whether bouillon will cause illness, so follow the storage and preparation directions. Harmful bacteria may not change how food looks or smells. Mold and moisture are the concerns for dry bouillon, and dissolved bouillon left out too long is a food safety risk like any broth. When in doubt, discard it.
Can you eat soup made with expired bouillon?
If the bouillon was dry, sealed and free of mold and off smells, the date is a quality question for cubes and granules. Better Than Bouillon advises discarding its paste past the Best By date. Refrigerate the finished soup promptly, keep it at 40°F or below, and use it within 3 to 4 days.
Can you make your own bouillon cubes or paste?
Homemade versions have no commercial label or shelf life, and we found no agency guidance for them. We’d treat them as perishable and refrigerate or freeze them, which is our own suggestion.
What can I make with bouillon?
Soup is the easiest use. We have recipes for red lentil soup, tortilla soup and clam corn chowder, among others. Check each recipe for the type and amount of broth it calls for.
