Canadian Cheddar Seafood Casserole Recipe

Serves/Makes: 8


  • 1 jar (10-ounce) Pacific oysters, cut in bite-sized pieces
  • 1 pound crab meat
  • 1 pound medium shrimp (about 32), cooked, shelled, and deveined
  • 7 tablespoons butter or margarine
  • 4 tablespoons all-purpose flour
  • 1 1/2 cups milk
  • 1/2 teaspoon salt
  • 1/4 teaspoon thyme leaves
  • 1/8 teaspoon each pepper and dry mustard
  • 2 1/2 cups shredded medium or sharp Cheddar cheese
  • 2 egg yolks, slightly beaten
  • 1/2 pound mushrooms, sliced
  • 1 tablespoon lemon juice
How to cook Canadian Cheddar Seafood Casserole:
  • In a 3-quart saucepan, melt 4 tablespoons of the butter; stir in the flour and cook until bubbly. Remove from heat and gradually add the milk; cook, stirring until thickened.
  • Add the salt, thyme, pepper, mustard, and 2 cups of the cheese; stir until cheese is melted. Add the egg yolks and cook over low heat 3 minutes longer; set aside.
  • Meanwhile, melt the remaining 3 tablespoons butter in a wide frying pan over medium heat; add the mushrooms and saute until lightly browned and the liquid is evaporated.
  • Add mushrooms and butter to the cheese sauce. To the frying pan, add oysters and their liquid; simmer until the edges begin to curl. Drain off liquid and stir oysters into sauce, along with the crab meat, shrimp, and lemon juice.
  • Turn mixture into a 2-quart casserole; sprinkle remaining cheese evenly over top. Cover and chill if made ahead.
  • Before serving, bake, uncovered, in a 375°F (190°C) oven until cheese is melted and mixture is heated through, 20 to 25 minutes (30 minutes if refrigerated).
