Chowder is a hearty soup that is perfect for cold winter nights. This tilapia chowder recipe is a lighter version of the classic New England clam chowder. The fish is simmered in a creamy broth made with potatoes, onions, and celery. Serve with a side of crusty bread for a satisfying meal. This recipe can also be made with other types of white fish, such as cod or haddock.
