Ingredients
Scale:
1 pound fresh shrimp, peeled and deveined
1 pound lump crab meat, preferably fresh
1 cup diced onion
1 cup diced bell pepper (red or green)
2 cloves garlic, minced
1/2 cup all-purpose flour
1 teaspoon Old Bay seasoning
1/2 teaspoon salt
1/4 teaspoon black pepper
2 cups whole milk
1 cup heavy cream
2 cups shredded cheddar cheese
1/2 cup grated Parmesan cheese
1 cup crushed butter crackers (like Ritz)
2 tablespoons melted butter
Instructions
Preheat your oven to 350°F (175°C).
In a large skillet, heat 2 tablespoons of butter over medium heat. Add the diced onion and bell pepper, cooking until softened, about 5 minutes. Stir in the minced garlic and cook for an additional minute until fragrant.
Sprinkle the flour over the sautéed vegetables, stirring constantly for about 2 minutes.
Gradually whisk in the milk and heavy cream, cooking the mixture until it thickens and bubbles, around 5-7 minutes.
Stir in the Old Bay seasoning, salt, and black pepper, mixing thoroughly.
Gently fold in the shrimp and crab meat, ensuring they are coated with the sauce.
Stir in the shredded cheddar cheese until melted and combined.
Pour the mixture into a greased 9x13-inch baking dish, spreading it evenly.
In a small bowl, mix the crushed butter crackers with the melted butter. Sprinkle this over the casserole, followed by the reserved cheese.
Bake for 25-30 minutes, or until bubbly and golden brown on top.
Allow the casserole to cool slightly before serving.
