Why You’ll Love This Crab and Shrimp Casserole:

Rich and Creamy: A savory sauce of butter, cheese, and mayonnaise creates a creamy, indulgent texture that complements the delicate seafood flavors perfectly.

Savory, Crunchy Topping: The breadcrumb topping adds a satisfying crunch and golden-brown color that contrasts beautifully with the creamy filling.

Versatile and Crowd-Pleasing: This casserole is ideal for family gatherings, dinner parties, or a cozy meal at home. It pairs well with salads, steamed veggies, and warm rolls.

Easy to Customize: You can add spices, herbs, or even extra seafood to make this casserole your own. It’s a versatile recipe that can be tailored to suit different tastes.

Key Ingredients:

Shrimp: Use peeled and deveined shrimp for convenience. Fresh or frozen shrimp both work well; if using frozen, be sure to thaw and drain them first to avoid extra moisture.

Crabmeat: Fresh crabmeat is ideal, but canned crabmeat works well and is more affordable. Check that it’s fully drained and free from shells.

Celery, Onion, and Garlic: These vegetables add a mild sweetness and aromatic base to the casserole, balancing the richness of the sauce.

Butter and Flour: These form the base of the roux, which thickens the sauce and gives it a creamy, smooth texture.

Milk: Milk makes the sauce creamy without being too heavy. Whole milk works best, but you can substitute with 2% milk or even half-and-half for an even richer sauce.

Mayonnaise: Adds a subtle tanginess and creamy texture. It also helps bind the sauce together.

Sharp Cheddar Cheese: Sharp cheddar melts well and brings a deliciously bold flavor that complements the seafood. Freshly grated cheese is ideal as it melts more smoothly.

Breadcrumbs: Breadcrumbs add a crunchy, golden topping to the casserole. Panko breadcrumbs can be used for an even crispier texture.

Salt and Pepper: Essential for seasoning the sauce and bringing out the flavors of the other ingredients.

Fresh Parsley: This garnish adds a pop of color and fresh flavor that balances the rich, creamy elements of the casserole.
