How to Make Crab and Shrimp Casserole
-
Preheat the oven to 350°F (175°C). This ensures that your casserole cooks evenly and reaches that perfect golden brown color on top.
-
Combine in a large bowl the shrimp, crabmeat, diced celery, garlic, and onion. Mix gently until all ingredients are well distributed; this forms the flavorful seafood base of your casserole.
-
Melt the butter in a saucepan over medium heat. Stir in the flour to create a roux and cook until bubbly and slightly golden to enhance its flavor.
-
Whisk in the milk gradually until the mixture thickens. Remove the saucepan from heat and then mix in the mayonnaise and shredded cheese, seasoning with salt and pepper to taste.
-
Pour the creamy sauce over the seafood mixture and stir carefully until everything is evenly coated with that delicious cheese sauce.
-
Transfer the mixture into a greased 9×13-inch baking dish; this helps ensure it doesn’t stick and is easy to serve later.
-
Sprinkle the breadcrumbs generously over the top for that delightful crunch. This will form a beautiful, crispy crust during baking.
-
Bake in the preheated oven for 30 minutes, or until the casserole’s top is bubbly and golden brown, showcasing all that comforting goodness.

Cool slightly before serving to allow the flavors to meld together; then garnish with freshly chopped parsley for a vibrant finishing touch.
