Storing and Reheating Tips

If you happen to have leftovers (which is always a lovely surprise), store the soup in an airtight container in the refrigerator, where it will stay fresh for up to 3 days. To reheat, simply pour it into a saucepan and heat on medium until warmed through. Adding a bit of broth can help refresh the flavors.

And if you have some more time, consider reheating it in the oven: pour the soup into oven-safe bowls, top with bread and cheese, and bake until the cheese is bubbling! It adds an irresistible texture to an already scrumptious dish.
