The Bisque is smooth and decadent. Chowder is thick and chunky. Traditionally, chowder is filled with pieces of vegetables and seafood. I love any seafood soup recipe, so I'm a big fan of chowder, too. Try my favorite Seafood Chowder recipe - you can make it shrimp chowder, crab chowder, or any mix you want, and it tastes amazing!
