Ingredients

• 4 tablespoons Butter
• 3 tablespoons All-purpose flour
• 2 cups Whole milk
• 1 cup Heavy cream
• 2 cups Sharp cheddar cheese, shredded
• 1 cup Parmesan cheese, grated
• 1 tablespoon Cajun seasoning
• 1 teaspoon Garlic powder
• 1 teaspoon Smoked paprika
• 1 pound Shrimp, peeled and deveined
• 1 pound Lump crab meat
• 1 cup Breadcrumbs
• 2 tablespoons Fresh parsley, chopped
• 2 tablespoons Olive oil
• 0.5 teaspoon Salt
• 0.5 teaspoon Black pepper

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish and set aside.

Step 2

In a medium saucepan over medium heat, melt the butter. Add the flour and whisk continuously for 1–2 minutes to make a roux.

Step 3

Slowly pour in the milk and heavy cream, whisking constantly to prevent lumps. Cook for 3–4 minutes, or until the mixture thickens.

Step 4

Stir in the shredded cheddar cheese and Parmesan cheese until melted and smooth. Add the Cajun seasoning, garlic powder, smoked paprika, salt, and black pepper. Mix well and remove from heat.

Step 5

In a large skillet, heat 1 tablespoon of olive oil over medium heat. Add the shrimp and cook for 2–3 minutes per side, until pink and opaque. Remove from heat.

Step 6

Gently fold the cooked shrimp and lump crab meat into the cheese sauce. Pour the mixture into the prepared baking dish.

Step 7

In a small bowl, combine breadcrumbs, fresh parsley, and the remaining olive oil. Sprinkle the breadcrumb mixture evenly over the seafood mixture in the baking dish.

Step 8

Bake in the preheated oven for 25–30 minutes, or until the top is golden brown and the mixture is bubbling around the edges.

Step 9

Remove from the oven and let rest for 5 minutes before serving. Garnish with extra parsley if desired.

Step 10

Serve warm with crusty bread or over rice for a hearty and delicious meal.
