A large hearty pot of lentil soup almost always leads to leftovers. Whether you simply made more than you can consume or made a large pot with the intention of keeping the leftovers for another day, freezing lentil soup preserves the leftovers for another night’s meal. Lentils are good source of protein and lentil soup has been warming people in a nutritious fashion since Biblical times. If you don’t plan on eating your leftovers in the next few days, keep them safely in your freezer until the craving strikes again.
Plug the kitchen sink and fill it a few inches with water and ice cubes.
Place the leftover soup in a container or its original pot into the ice water to cool off. Leave the soup to chill for 20 to 30 minutes. Replace the ice cubes and add more cold water as the ice melts.
Ladle the soup into ice cube trays gently so as not to spill it.
Freeze the ice cube trays in a flat area of your freezer until the cubes of soup are solid. The soup will need a couple hours to solidify.
Remove the cubes from the tray and place them into freezer bags marked with the current date. Use a permanent marker to keep the date from wearing off of the bag.
Keep the frozen soup for up to six months in your freezer.
