Soup is the perfect winter meal, and it’s always a good idea to keep some soup in your freezer.
This way, you can still enjoy hearty soups when you don’t feel like cooking but need something warm and wholesome in no time.
Onion soups typically find themselves in the awkward place of being too close to raw onions when freezing soup.
This can prevent the taste from coming through as strongly, but these soups are still worthy contenders for hearty winter meals.
Can you freeze onion soup? An airtight container can keep it frozen for up to three months.
Allow the soup to cool completely before refrigerating.
You may want to divide the soup into portions before freezing to be able to reheat each portion when you get home from work on a cold night.
The freezing onion broth is simple, but it requires some basic knowledge and a few extra steps.
How to Properly Freeze Onion Soup?
It is easy to freeze onion soup.
You need to follow only a few steps to ensure your soup stays safe in the freezer.
These are the steps you need to take to freeze onion soup properly:
The soup should be cooked as usual. If you plan to freeze some soup, make sure to remove any portion that is not being used.
This step helps preserve the onion’s texture and prevents it from becoming too soft or mushy when thawed and then reheated.
If this is not possible, you can cook the soup according to your favorite recipe.
Let it cool down – Hot food cannot be stored in the freezer.
This can lead to condensation in the freezer container, which can then cause poor quality food and freezer burn.
Instead, let the onion soup cool at room temperature.
You can heat the soup in a bowl or pot and then pour ice water into your sink if you’re in a hurry.
It will cool down a bit faster if you stir it frequently. To speed up the cooling process, you can portion out the soup.
If you plan to freeze the entire batch for a family meal, you can put it in a large freezer bag or container.
If you have a leftover soup that is too large to be eaten in one sitting, it will be necessary to freeze it in smaller containers.
Choosing Containers to Store Onion Soup
There are many options for freezer storage when you freeze soup.
Quart-size freezer Bag: A Quart of freezer bags can store one serving of soup.
Freezer bags are great because you can stack them up and save space.
Frozen soup in freezer-safe containers: Choose the appropriate size container to fit your portion and ensure that the lid is tight.
Rubbermaid Brilliance Collection glass containers are our favorites.
Muffin trays: Freezing onion soup in muffin pans is a wonderful trick.
Here’s how you do it:
Allow the onion soup to cool in a bowl and then pour it into muffin cups—Bake for 20 minutes.
You can freeze the muffin tin for up to two hours or overnight.
Once frozen, place it on the counter and let it sit for up 20 minutes.
This allows you to remove individual soup portions easily.
All of the portions should be removed and placed in a large plastic bag.
This method allows you to freeze individual portions of the soup while keeping them separate but kept in the same bag.
You can quickly grab a handful to heat up when you are ready and don’t have to defrost it all.
How Long can Onion Soup Be Frozen?
Onion soup can be stored in the freezer for up to three months if properly stored and handled.
Although it will still be delicious, it will not taste as good after three months.
If refrigerated, onion soup can be enjoyed in 3 to 4 days.
If you want to extend the shelf-life of onion soup, it is better to freeze it to make sure it doesn’t spoil before you eat it.
The soup may also taste a little different after being frozen for a long period.
This does not mean it is bad to eat; simply that you should expect the soup to taste different.
If you are not going to eat the soup after three months, it is best to throw it away.
Is it Possible to Refreeze the Thawed Onion Soup?
You might refreeze onion soup if you’ve thawed large amounts of it.
Once onion soup has thawed, it is unsafe to refreeze it.
The same applies to most food once it has thawed.
Although you might be able to refreeze onion soup if it has been left to thaw inside the fridge and ice crystals, it is not recommended.
Refreezing onion soup that has been thawed is even more dangerous.
After being reheated, thawed, and reheated, any soup leftover should be thrown out and not stored in the refrigerator.
The risk of food-borne illness is too high. After reheating, the onion soup will be of poor quality.
It is, therefore, a smart choice to freeze individual portions.
This allows you to thaw as many portions as you think you will finish in one meal without worrying about over-eating.
Does Onion Soup Expand When Frozen?
The answer is yes.
If you want to avoid onion soup expanding in the freezer, do not fill the container all the way.
You should leave some room for expansion to prevent the container from breaking when it freezes.
If you don’t allow for expansion when filling the container, the onion soup may pop out of the bag or container in your freezer and make a mess.
How to Reheat Frozen Onion Soup?
It is best to let the onion soup sit in the fridge overnight to allow it time to thaw before you prepare it for reheating.
Reheat it by either placing the packaged soup in a microwave or on the stove.
If you are using a microwave, make sure to heat for 3 minutes at full power.
Stovetop reheating might require more time and a bit of stirring to make sure it heats evenly.
How to Tell if Onion Soup Has Gone Bad?
It is hard to tell whether onion soup has gone bad just by looking at it as the color doesn’t change.
You can only determine whether your onion soup has gone bad or not by smell and taste alone.
If there are any signs of mold, the onion soup has gone bad and shouldn’t be eaten.
If it smells strange or has an off flavor, you should avoid eating it.
Any onions that have not been cooked and still retain their raw texture should also be thrown out.
If your onion soup doesn’t taste fresh anymore, you should toss it and make a new batch rather than risk getting ill from the old one.
If your soup looks normal and smells fine, you can still give it a taste test before serving.
If you are certain that your soup hasn’t gone bad and still has a fresh smell and taste, feel free to enjoy it.
In conclusion, onion soup can be frozen, but only for short periods.
It is best to start with a fresh batch instead of reusing old onion soup if you plan to freeze it.
Freezing does not affect the taste of your soups that much, so enjoy them.
If you plan to reheat your onion soup, it is best to let it sit overnight in the fridge to thaw properly.
Keep these guidelines in mind, and you should be fine.
Enjoy your soup.
