| Chopped parsley | 1/2 teaspoon (optional) |
Step-by-Step Instructions
1. Prepare Your Seafood
Start by rinsing the flounder, shrimp, scallops, and crabmeat under cold water. Pat them dry with paper towels to remove excess moisture. Divide the flounder fillets into two portions for even cooking.
2. Sauté the Seafood
In a large skillet, melt 2 tablespoons of butter over medium heat. Add the shrimp and scallops, and cook for 2-3 minutes on each side until lightly golden. Deglaze the pan with a splash of white wine, letting the alcohol cook off. Remove the shrimp and scallops and set them aside.
3. Make the Creamy Sauce
Using the same skillet, melt 4 tablespoons of butter. Stir in a small amount of flour to create a roux. Gradually whisk in the chicken stock and heavy cream, ensuring there are no lumps. Add the Dijon mustard, garlic powder, onion powder, and black pepper. Let the sauce simmer for 3-5 minutes until it thickens slightly.
4. Assemble the Casserole
Preheat your oven to 375°F (190°C). In a baking dish, layer the flounder fillets at the bottom. Top with the sautéed shrimp, scallops, and crabmeat. Pour the creamy sauce over the seafood, ensuring everything is evenly coated. Sprinkle with Old Bay seasoning and chopped parsley for added flavor.
5. Bake the Casserole
Cover the dish with foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes, allowing the top to lightly brown.
Tips for the Best Seafood Casserole
- Fresh is Best: Opt for fresh seafood whenever possible. Frozen seafood works too, but ensure it’s thawed completely before cooking.
- Don’t Overcook: Seafood cooks quickly, so be careful not to overdo it during the sautéing and baking process.
- Customize Your Protein: Not a fan of flounder? Swap it for cod or another white fish.
