If you have leftovers, let the soup cool completely before transferring it to an airtight container. It can be stored in the refrigerator for up to three days. Reheat on the stove or in the microwave until warmed through. If you plan to freeze it, omit the bread and cheese, as they do not freeze well. The soup can be frozen for up to three months.
