Seafood au gratin is loaded with melted cheese, buttery flavor and flaky, tender fish and scallops. For picky eaters, the cod and scallops are mellowed by the cheese, making it a lovely dish to serve those with skeptical taste buds.

Ingredients

  • 1 pound haddock or cod fillets, cut into six pieces
  • 1/2 pound sea scallops
  • 4 tablespoons butter, divided
  • 2 tablespoons all-purpose flour
  • 1/8 teaspoon pepper
  • 1 cup chicken broth
  • 1/2 cup 2% milk
  • 1/2 cup grated Parmesan cheese, divided
  • 1/2 cup shredded part-skim mozzarella cheese, divided
  • 1/2 cup shredded cheddar cheese, divided
  • 1-1/2 cups sliced fresh mushrooms
  • Minced chives, optional

Directions

  1. Preheat oven to 350°. Arrange fish and scallops in a greased 11x7-in. baking dish.
  2. In a small saucepan, melt 2 tablespoons butter. Stir in flour and pepper until smooth; gradually add broth and milk. Bring to a boil; cook and stir 2 minutes or until thickened. Stir in 1/4 cup of each cheese; set aside.
  3. In a small skillet, saute mushrooms in remaining butter until tender; stir into cheese sauce. Spoon over seafood. Sprinkle with remaining mozzarella, cheddar and Parmesan cheese. Cover and bake 15-20 minutes or until bubbly and fish flakes easily with a fork. If desired, top with chives to serve.

A seafood casserole is a ‘must’ for a bountiful buffet. My father was a fisherman, so we ate fish almost every day. Over the years, I’ve tasted many seafood dishes, but none better than this one. —Hazel McMullin, Amherst, Nova Scotia
