Freeze

This soup can easily be frozen! After it has cooled completely, transfer to a freezer safe container. It will last about 6 months but will have the best texture within 3 months. If you freeze it in a ziplock bag lying flat on a shelf, then you will be able to store it upright without taking up as much space!

Reheat

Talk about easy. To reheat individual portions of the soup, simply microwave a bowl of this in 30 second increments. For larger servings, reheat in a large pot on the stove. Set the heat to medium and stir frequently until the entire soup is warmed.
