This hearty and comforting chowder is made with tender chunks of cod, potatoes, and vegetables in a creamy broth. The fish is cooked in a flavorful base made with onions, celery, and garlic, which infuses it with a rich and savory taste. The chowder is thickened with a roux made with butter and flour, which gives it a creamy and velvety texture. This recipe is perfect for a cold winter night, and it pairs well with a crusty bread or crackers.
