Onion soup is a French specialty that’s easy to make at home. It’s a delicious way to use up those leftover baked potatoes, or serve it as an appetizer with a fresh baguette and a glass of wine. If you end up with some leftover onion soup, you may wonder if you can freeze them for later.

How Long Does Onion Soup Last In the Freezer?

Properly stored, onion soup will last for about 3 months in the freezer.

After that time, each month that passes by, the less flavorful it will become as ingredients like onions start to break down over time. You’ll be able to tell how fresh your frozen onion soup is by how much flavor it has when cooked again on the stovetop or microwave.

How To Defrost Onion Soup

If you’ve frozen onion soup, and now you want to use it, there are a few options. First, you can put the soup in your fridge overnight. This will allow it to defrost without getting too warm. This is the best option since it will allow the onion soup to defrost slowly without affecting the texture or taste.

Next, you can defrost the soup in a pot on the stove or in your microwave. However, if you do so with a heating pad wrapped around it so that it stays at an even temperature while defrosting (this is especially important if using a microwave).

If using this method, be sure that once the onions have softened enough for your liking that you remove them from heat and set them aside before adding any liquids back into them.

Also, try not to stir too much after adding broth either—this will cause more onions than desired into your bowl!

Can You Refreeze Onion Soup?

When it comes to onion soup, you should not refreeze it. Freezing onion soup more than once can have a few effects on the flavor and texture. Below are two of them:

1. Freezing will make them less flavorful. The heat from cooking helps release their natural juices; if those juices are frozen, they won’t evaporate into the air as much during reheating—which means your soup won’t have as much of that delicious oniony taste!

2. Freezing will change the consistency of your soup. When we freeze things (particularly liquids), ice crystals form around molecules inside them in order to make space for more water molecules underneath them—which generally makes foods harder and less creamy when they’ve thawed out again (think about how ice cream gets more solid as it melts). This means that freezing more than once makes soups less creamy by changing their texture!

Does Onion Soup Freeze Well?

Yes, onion soup freezes well. But the question is whether it tastes as good as fresh onion soup.

The main ingredient in onion soup is onions, and onions are pretty much immune to freezing. They don’t lose their flavor or texture when frozen, so there’s no reason not to freeze your onion soup if you want to enjoy it later on.

However, freezing will change the texture of the broth, which is why homemade onion soup doesn’t taste quite as good as freshly made onion soup. To avoid this problem, make sure you use homemade broth instead of store-bought broth when making your onion soup.

If you’re going to freeze your onion soup, I recommend preparing it in individual servings rather than cooking the entire batch at once and freezing half of it. This way you’ll be able to enjoy your homemade onion soup right away instead of waiting for it to thaw out in the refrigerator before serving it for dinner!


While we don’t recommend freezing onion soup, we understand that it can be a useful tool for those who have excess food. If you do decide to freeze this dish, keep in mind that it will lose some of its flavor and texture when it is thawed. However, if you make sure to store the soup in an airtight container with a label on it so people know what they are eating then there shouldn’t be any problems!
