Do Bouillon Cubes Go Bad?

Here’s all you need to know about the shelf life, storage, and spoilage of bouillon cubes. Learn whether bouillon cubes go bad, how to store them, and how to tell if one is spoiled.

No time to make chicken stock? With bouillon cubes, you can make it in minutes. But as they come in packs, sooner or later, you will end up with old cubes. Do bouillon cubes go bad?

Or maybe your cubes are past their date, and you’re wondering if they’re still okay to use.

Either way, it’s time for you to learn a thing or two about bouillon cubes.

Sounds interesting? Let’s get right into it.


All the info below applies to all sorts of bouillon cubes, including chicken stock cubes, beef cubes, veggie broth cubes, and other similar products.

How To Store Bouillon Cubes

Bouillon cubes are convenient not only because they allow you to make a pot of broth in mere minutes, but also because they don’t need much in terms of storage.

The cubes are shelf-stable, and all they need is a cool and dry place. A cabinet in the kitchen or pantry is perfect. Or you can do like I do and keep the cubes in the same place I store spices.

I’m sure you already know that, but I wanted to mention that anyway: you should refrigerate the stock you prepared with the cubes, just like you do with homemade or open chicken stock or vegetable broth.

Now that we’ve covered storage, let’s talk about the shelf life of the dehydrated version of broth.

How Long Do Bouillon Cubes Last?

Bouillon cubesBest-by + 3+ months for the best quality

Bouillon cubes come with a shelf life of between a year and 18 to even 24 months, and they easily keep quality for at least a couple of months beyond the printed date. That’s no matter if or when the package has been opened, assuming that you keep the cubes sealed and in a cool and dry place.

The shelf life of bouillon cubes varies between producers. But if you’ve discarded the package with the date and only have the cubes, you can safely assume they can last at least a year and probably much longer.

Out of Date Stock Cubes

Bouillon cubes and powder typically retain quality for at least 3 months beyond the printed date. That’s about the minimum period, provided that you store them properly.

Unfortunately, there’s no way to tell exactly how long bouillon powder is good for after the “expiration” date. So that rough estimate is the best I can give you.

Truth be told, it’s probably better to pay attention to the quality of the cubes than the date printed on the label.

One thing that’s for sure is that stock cubes don’t go bad right away. Of course, over time the flavor will weaken and become duller, but unless you mess up the storage, they should be okay to use for another couple of months at least.


If your old bouillon cubes lack flavor, consider adding more cubes to account for that.

Having said that, bouillon cubes can spoil. Let’s talk about what the signs of that are.

How to Tell if a Bouillon Cube Is Bad?

Checking if your instant broth cubes are still fit for consumption is similar to checking other dried products. Here are the things you should look out for:

  • Mold, or any other changes in color. Any white specks are a sure sign you should discard the cube.
  • Altered smell. Like with almost any food, if it smells off, it’s gone.
  • Off taste. If your cubes are way past their date, prep half a cup of broth as a test. All you need is a half cup of boiling water and one-fourth of a bouillon cube. If it tastes bad, get rid of it.

Want to make a big pot of soup with those old cubes? Make sure you run the taste test I described above. All it takes is a couple of minutes, and it might prevent you from a culinary disaster.

If your cubes break apart easily, that might mean they are quite old, and the quality of the broth cooked with them might not be that yummy. You won’t know that until you give that to a test, though.

Again, if the flavor is somewhat lacking, try adding more cubes to make up for that.

Finally, once you cook soup using your bouillon cubes, the soup lasts between 3 to 4 days.
