How to Store Leftover French Onion Soup?

Whether you have leftover soup or just want to keep a bowl of it in preparation for a chilly day in the future, there are several ways you should follow to ensure your soup stays appetizing and healthy.

Important Storing Reminders

Reminder 1:

You have to make sure that the soup is completely cooled down at room temperature. This will make sure that the container you packed them in doesn’t get wet.

Reminder 2:

Remove the cheese or crouton from the soup once it’s cooled. These two ingredients don’t freeze well and can ruin the soup.

Reminder 3:

The soup can be put in a sealed container or a freezer bag.

When freezing your French onion soup, only use these two types of containers, as they keep the soup in a vacuum-like environment and hopefully from going tasteless.

You can thaw all of the soup if you keep them in individual portions.

Reminder 4:

The date of freezing as well as the estimated “expiration date”, which is after three months, should be placed on the container.

If you have more than one freezer, make sure to label the one you are using to store the soup.

How Long Is It Possible to Freeze French Onion Soup?

You can keep the soup frozen for up to three months if you follow the reminders and don’t miss any.

Depending on the container you use, as well as the spot on the freezer you placed it on, the duration can be different.

French onion soup can remain safe to eat for as long as four to six months, if one takes the proper steps in packaging and storing them, according to some French onion soup enthusiasts.

How Long Is It Possible to Keep French Onion Soup in the Fridge?

A lot of people don’t plan on keeping their French onion soup for very long. Some people just want to eat soup every day for as long as it remains good.

It’s enough for them to keep the soup in the fridge. The good news is that you can keep French onion soup in the fridge for up to four days if you keep it in the right container.

If you want to enjoy the soup’s flavor after the time has elapsed, then freezing it will be your best choice.

You don’t need to store it in a container if you store it in a heavy-duty freezer bag.

How to Thaw and Reheat French Onion Soup?

If you already have a craving for a hot bowl of French onion soup, you can simply remove it from the freezer and let it thaw overnight at room temperature.

If you don’t want to wait until the next morning, just prepare a warm tub of water and place the soup container or freezing bag into it.

Once the ice has melted, you can prepare to cook the soup again. There is a quick process to make sure the soup is reheated correctly.

Using an Oven

  • The temperature in the oven should be around 350F to 400F (175C to 200C).
  • The soup should be reheated for 15 minutes after being laddled in the ovenproof bowl.
  • Take the soup out of the oven after time has elapsed.
  • Return your shredded cheese to the oven after you add it.
  • Wait for three to five minutes until the cheese has melted, then turn your oven off.

Using a Microwave

  • The soup should be placed in a microwave-safe bowl.
  • Reheat your soup by placing the microwave on high for 3 minutes.
  • Make up a fresh crouton.
  • Add the crouton after removing the soup from the microwave.
  • For another minute, heat the soap.

You can continue enjoying your French onion soup by doing that. French onion soup can last for at least three months if you freeze.

Difference Between Onion Soup And French Onion Soup

But before you go and start making your French onion soup, let’s clear the confusion surrounding the difference between a French onion soup and a regular onion soup, aside from the word FRENCH.

On the other hand, English onion soup uses beef, chicken, or vegetable stock to make it. Adding red wine or sherry to your French onion soup will make it as good as the authentic version.

There is a difference between the cheese and bread in the onion soup. French onion soup is usually topped with French bread or baguette or Emmental and/or Swiss cheese.

English onion soup is usually made with bread and cheese, whereas French onion soup is usually made with bread and cheese.

If you want to learn more about these differences, you might need to ask a French chef.

This national treasure, which can be traced back to 8000 years ago in Ancient Rome, has undergone many changes throughout its history.

In the 18th century, when it was made with onions, beef, wine, and bay leaves, it was well-received by connoisseurs and regular diners.

Two things remain the same about this dish: the need for a bunch of onions in different colors, sizes, and types, as well as the storage process.
