Seafood Chowder Casserole

New England seafood chowder inspired the flavors here, but we’ve enhanced them further with Gruyère cheese and a crispy crumb topping. We like the combination of shrimp, cod and crab, but feel free to experiment with other types of seafood–scallops, clams and mahi-mahi would also work well. Source: EatingWell Magazine, September/October 2010


  • 1 tablespoon plus 1 teaspoon canola oil, divided
  • 2 cups sliced leeks, rinsed (about 2 small)
  • 1 cup sliced celery
  • 2 large white potatoes (about 1 3/4 pounds), peeled and cut into 3/4-inch pieces
  • 2 cups seafood stock or clam juice (see Tips)
  • 2 teaspoons Old Bay seasoning, divided
  • ½ teaspoon freshly ground pepper
  • 1 cup low-fat milk
  • ¼ cup all-purpose flour
  • 1 tablespoon Dijon mustard
  • 1 pound raw shrimp (21-25 count), peeled, deveined and chopped (about 2 cups; see Tips)
  • 12 ounces diced cod (see Tips) or other firm white fish
  • 8 ounces pasteurized crabmeat, preferably jumbo, drained
  • 2 cups shredded Gruyère cheese, divided
  • 2 tablespoons chopped fresh dill or 2 teaspoons dried, divided
  • 1/2 cup coarse whole-wheat breadcrumbs (see Tips)

Directions :

  • Step 1:Preheat oven to 400 degrees F. Coat a 9-by-13-inch (or similar 3-quart) baking dish with cooking spray.
  • Step 2:Heat 1 tablespoon oil in a Dutch oven over medium-high heat. Add leeks and celery and cook, stirring often, until the leeks are softened, 2 to 3 minutes. Stir in potatoes, stock (or clam juice), 1 teaspoon Old Bay and pepper. Cover and bring to a simmer over high heat. Reduce heat to medium-low and simmer, covered, until the potatoes are just tender, 6 to 8 minutes.
  • Step 3:Whisk milk, flour and mustard in a measuring cup. Stir into the potato mixture, increase heat to medium-high and bring to a simmer, stirring constantly. Stir in shrimp and fish and return to a simmer, stirring often; cook until the seafood is just cooked through, about 3 minutes. Remove from the heat and stir in crab, 1 1/2 cups Gruyere and half the dill.
  • Step 4:Transfer the seafood mixture to the prepared baking dish. Mix breadcrumbs with the remaining 1 teaspoon each oil and Old Bay. Stir in the remaining 1/2 cup Gruyere and the remaining dill. Sprinkle the breadcrumb mixture over the casserole.
  • Step 5:Bake the casserole until it is bubbling and golden brown, 20 to 30 minutes. Let stand 10 minutes before serving.
