This slow cooker fish chowder is made with frozen, thawed fish fillets. Make this chowder with haddock, cod, catfish, pollock, or a similar firm white fish.

Serve the chowder with oyster crackers or crusty rolls. Add a tossed salad for a satisfying family lunch or dinner.

Feel free to change it up with some corn for a fish and corn chowder, or add some celery. You could also add shrimp or another seafood near the end of the cooking time for a seafood chowder.

  • 1/4 pound bacon, or streaky salt pork, diced

  • 1 medium onion, coarsely chopped

  • Thaw frozen fish fillets in the refrigerator overnight. To thaw quickly, put fillets in a zip-close plastic food storage bag. Push as much of the air out of the bag as possible and then seal the bag. Place the bag with the fish in a large bowl. Cover the fish with cold water and keep the fish submerged with something heavy. A big jar of spaghetti sauce, salsa, or jam will work well. Change the water frequently to keep it at or a little below 40 F. The fish should be thawed in about 30 to 45 minutes. 

Recipe Variations

  • Instead of water, add clam broth, or chicken stock (preferably unsalted) to the slow cooker.
  • Add about 1/2 cup of sliced celery to the skillet with the onions.
  • Sauté about 1/2 cup of diced carrot along with the onion.
  • Add 1 to 1 1/2 cups of corn kernels to the chowder.
  • Add 4 tablespoons of butter to the chowder along with the evaporated milk.
  • Add a small can of minced clams to the pot along with the fish.
  • Add 1 pound of medium peeled and deveined shrimp with the evaporated milk and continue cooking until the shrimp is opaque.
