How To Freeze French Onion Soup

  1. Cool
    If you’ve recently cooked the french onion soup, you’ll want to wait for it to completely cool before starting the freezing process. Hot soup won’t freeze well and can melt your container.

    Be sure to remove any cheese or croutons from the soup because they won’t freeze well.
  2. Portion Into Bags
    Once your soup has completely cooled, spoon the desired amount into a freezer bag or a freezer-safe container. Consider separating the soup into smaller bags for individual servings.

    This way you don’t have to thaw an entire bag when you only want a little bit.
  3. Label
    Grab a marker and be sure to write the date you’ve frozen the soup on the front of the container so you know how long it’s been in there.
  4. Freeze
    Place the containers in a convenient spot in your freezer and you’re good to go!
