It is that time of year where a hot bowl of soup really hits the spot on a cold winter day. When you come in from a long day at work or even a long day of play to a steaming bowl of soup it can really help to relax you. 

Perhaps you made too much onion soup and are now needing to know how you can store the leftovers. Maybe you are wanting to make a big batch of soup to have it on hand for cold days. 

You will be glad to know that you can freeze onion soup. Although you do have to let it cool before putting it in the freezer it can be frozen. 

Can You Freeze Onion Soup?

French onion soup is served with cheesy croutons on top. If you want to freeze your onion soup you will simply need to prepare the soup as you normally would up until you add the croutons. 

Once you have cooked the soup you will want to allow it to cool completely. After the soup has cooled, you will need to gather some clean freezer safe containers with tight fitting lids to place the soup in. Carefully spoon the soup into the containers. You will want to leave a little bit of room at the top of the container so that the soup can expand as it freezes without worry of the container breaking.

Secure the lid tightly to the container and label it with the date and contents. Then once you thaw out the onion soup when you are ready to eat it you will simply add the cheesy croutons on top at that point.

Can You Freeze Soup With Onion In It?

There are a lot of soups that contain onion. In fact, many of the soups that I make have at least a small amount of onion in them which is great since I love onions. 

Onion is aromatic and it can really add a lot of flavor to your soups. 

There are some soups that you will not want to freeze, such as soups that contain dairy. Soups that contain dairy do not freeze as well as other soups. So, is it alright to freeze soups that have onion?

You can freeze pretty much any soup that contains onion. Onion holds up well in the freezer and in fact, if you have a lot of onions that you do not think you will use before they go bad you can simply dice or slice your onions and freeze them by themselves as well.

I keep a few bags of diced onions in my freezer for those times when I am in a hurry or don’t feel like cutting fresh onions. The taste and texture of the onions holds up well in the freezer as well. 

When you are going to freeze soup, you first need to make sure that you have allowed the soup to cool down to room temperature. It is best to have freezer safe containers that are the serving size that you will be wanting to use when you thaw the soup as well. 

I divide soups up into individual serving size containers as well as family size containers. This means anyone in the family can grab a container of soup for lunch or we can grab a larger container for a quick dinner for the whole family. 

Once you have your containers picked out you will want to spoon your soup into them. Leave room at the top of your container for the soup to expand as it freezes. Tightly secure the lid and label your container with the date and the contents. 

Most soups (including onion soup) will be good in the freezer for three months.

Can You Freeze And Reheat French Onion Soup?

French onion soup is a decadent soup in a rich broth and is filled with caramelized onions. The soup is then topped with cheesy croutons. 

French onion soup can be made in advance and then you can freeze and reheat it as needed. 

A good French onion soup has two main ingredients. The stock and the onions. 

Typically, French onion soup is made with beef stock. You will want to make sure that the stock that you are using is a good quality one. You can make the stock yourself or you can purchase a boxed stock from your local grocery store. 

If you are going to purchase a beef stock you will want to make sure that it has a good flavor to it. I have purchased some boxed beef stock before only to discover that I did not care for the flavoring of it at all. I ended up tossing it out and using something different for my recipe. 

Give your broth a small taste before you use it to make your soup. If you don’t like the taste of the beef broth you are going to use, you will not like the taste of the soup. 

The second thing you need to make French onion soup is caramelized onions. Properly caramelizing the onions will take anywhere from 25 to 30 minutes. You will need to slice your onions and then place them in a heavy bottomed pan with about 3 tablespoons of olive oil. 

Set your burner to a medium heat. Place your onions in the pan and stir them to coat them in the oil. You will need to stir the onions often while they are cooking. 

The onions should be softened after about 15 minutes. Once they are soft you will increase the heat to medium high and add about a teaspoon of olive oil and butter. Allow this to cook for about 15 more minutes, stirring often. 

The onions will begin to brown and then you can sprinkle a little sugar on the onions to help get that deep caramel color and rich flavor. Once your onions have caramelized you will place the rest of the ingredients into your pot and allow the soup to cook. 

If you are planning to freeze your French onion soup you will want to stop once your soup has finished cooking. Do not add the cheesy croutons. Allow your soup to cool to room temperature before placing it into freezer safe containers. 

Be sure to label your containers with the date and the contents. French onion soup will be good in the freezer for up to 3 months. 

When you are ready to reheat your soup, simply remove it from the freezer. Place it into a pan and warm it up over a medium heat. While your soup is warming up you can prepare some croutons or toasted bread with cheese. 

Parmesan and Gruyere cheese both pair well with French onion soup. Toast your sliced bread or croutons then top with the cheese and return them to the oven until the cheese is lightly browned and bubbly. 

Ladle the soup into bowls and then place a slice of toasted bread and cheese over each bowl and enjoy.
