Description

A rich and flavorful Crab and Shrimp Casserole featuring tender seafood baked in a creamy vegetable sauce topped with cheddar cheese and crispy breadcrumbs. This comforting dish combines sautéed aromatics with a velvety sauce seasoned with Old Bay, perfect for a hearty family meal or special occasion.


Ingredients

Scale

Seafood

  • 1 pound lump crabmeat
  • 1 pound large shrimp, peeled and deveined

Vegetables and Aromatics

  • 1 cup chopped onion
  • 1 cup chopped bell pepper
  • 1 cup chopped celery
  • 2 cloves garlic, minced

Sauce

  • 1/4 cup butter
  • 1/4 cup all-purpose flour
  • 2 cups milk
  • 1 cup chicken broth
  • 1 teaspoon Old Bay seasoning
  • Salt and pepper to taste

Topping

  • 1 cup shredded cheddar cheese
  • 1 cup breadcrumbs

Garnish

  • Chopped fresh parsley for garnish


Instructions

  1. Preheat Oven: Preheat the oven to 375°F (190°C) and grease a 9×13-inch baking dish to prevent sticking and prepare it for the casserole mixture.
  2. Sauté Vegetables: In a skillet, melt the butter and sauté chopped onion, bell pepper, celery, and minced garlic over medium heat until the vegetables are softened and fragrant, about 5 minutes.
  3. Make Sauce: Sprinkle the flour over the sautéed vegetables and cook, stirring constantly, for about 1-2 minutes to form a roux. Gradually whisk in the milk and chicken broth, stirring continuously until the sauce is smooth and thickened, about 5-7 minutes.
  4. Season and Combine Seafood: Stir in Old Bay seasoning, salt, and pepper to the sauce. Gently fold in the lump crabmeat and peeled shrimp ensuring the seafood is evenly coated with the sauce.
  5. Assemble Casserole: Pour the crab and shrimp mixture into the prepared baking dish. Evenly sprinkle the shredded cheddar cheese and breadcrumbs over the top to create a flavorful crust.
  6. Bake: Bake in the preheated oven for 25-30 minutes or until the casserole is bubbly and the topping is golden brown.
  7. Garnish and Serve: Remove from the oven and let it cool slightly. Garnish with freshly chopped parsley before serving to add a fresh, bright finish.

Notes

  • Use fresh or thawed seafood for the best texture and flavor.
  • Old Bay seasoning can be substituted with Cajun seasoning for a different spice profile.
  • For a richer casserole, substitute whole milk with half-and-half or add a splash of cream.
  • Breadcrumbs can be replaced with crushed crackers for added texture.
  • Make sure not to overcook the seafood in the sauce to avoid rubbery texture; it will continue cooking in the oven.
