Leftover cioppino soup can be stored in the fridge in an airtight container for up to two days. Reheat gently over low heat. Avoid boiling, since high temps can make the seafood tough. If you want to be extra careful, you can remove any seafood pieces before reheating the broth, warm the broth, and then add the seafood back in at the end. Some people even say cioppino recipes taste better the next day because the flavor keeps deepening overnight. Hello, bonus recipe: I see you!
One of the hidden gems in this recipe is the tomato-saffron broth. Before you add a single piece of fish, you've already created a remarkable soup. The roasted tomatoes, fennel, saffron, wine, and fish stock make a rich, velvety base that's delicious all on its own. Serve it as an appetizer with a dollop of ricotta, fresh parsley, and charred garlic bread for a light and yummy meal.
