Ingredients

To make this flavorful Seafood Casserole, you will need the following ingredients:

For the Casserole:

• 1 lb (450g) shrimp, peeled and deveined: Shrimp adds a sweet and succulent flavor, and it cooks quickly.
• 1 lb (450g) white fish fillets (such as cod or haddock), cut into bite-sized pieces: A mild fish that adds texture and absorbs the flavors of the sauce.
• 1/2 lb (225g) scallops, halved (optional): For an added touch of luxury, scallops bring a delicate sweetness and richness to the dish.
• 1 cup lump crab meat (optional, but recommended): Adds a rich, slightly sweet flavor that complements the seafood medley.
• 1 small onion, finely chopped: The onion provides a savory base for the sauce and enhances the overall flavor.
• 2 cloves garlic, minced: Garlic adds depth and aromatic richness to the sauce.
• 1 cup frozen peas: Adds a pop of color and a touch of sweetness to the casserole.
• 2 cups heavy cream: Creates the rich, creamy base that binds everything together.
• 1/4 cup dry white wine: The wine adds a subtle acidity that balances the richness of the sauce.
• 2 tablespoons butter: Adds flavor and helps create the smooth texture of the sauce.
• 1 tablespoon all-purpose flour (or gluten-free flour if needed): Thickens the sauce for a velvety finish.
• 1 teaspoon Old Bay seasoning (or your favorite seafood seasoning): Adds a punch of flavor that pairs beautifully with the seafood.
• 1 teaspoon dried thyme: A fragrant herb that complements the seafood and adds a bit of earthiness.
• Salt and black pepper to taste: Essential for seasoning.
• 1 1/2 cups shredded cheddar cheese: A classic topping that melts into the casserole and creates a crispy, golden crust.
• 1/2 cup breadcrumbs (optional, for topping): Adds a nice crunch to the casserole. You can use gluten-free breadcrumbs if needed.

For the Garnish:

• Chopped parsley: Adds a fresh, bright touch and color to the dish when served.
• Lemon wedges: For a burst of acidity that balances the richness of the casserole.

Step-by-Step Instructions

STEP 1: PREHEAT THE OVEN AND PREPARE THE SEAFOOD

Start by preheating your oven to 350°F (175°C). Prepare a large baking dish (9×13-inch) by lightly greasing it with butter or cooking spray.

Next, prepare your seafood. If you’re using shrimp, peel and devein them. Cut the white fish fillets into bite-sized pieces. If you’re using scallops, cut them in half or quarters. If you’re using lump crab meat, be sure to check for any shell pieces and remove them.

STEP 2: MAKE THE CREAMY BASE

In a large skillet, melt the butter over medium heat. Add the chopped onion and minced garlic, and sauté for about 3-4 minutes until softened and fragrant.

Sprinkle the flour over the onions and garlic and stir to combine. Cook for an additional 1-2 minutes to eliminate the raw flour taste.

Slowly add the heavy cream, stirring constantly to prevent lumps. Once the cream has been incorporated, pour in the white wine and stir to combine. Bring the mixture to a gentle simmer, cooking for about 5 minutes until the sauce thickens.

Add the Old Bay seasoning, dried thyme, and a pinch of salt and pepper. Taste and adjust the seasoning if needed.

STEP 3: COMBINE THE SEAFOOD AND SAUCE

Once the sauce has thickened, add the seafood—shrimp, fish, scallops, and crab (if using)—to the skillet. Gently stir to coat the seafood in the creamy sauce. Be careful not to break the fish apart, as you want to keep the pieces intact.

Stir in the frozen peas and cook for another 2-3 minutes until the seafood is just starting to cook through. It doesn’t need to be fully cooked at this stage, as it will continue to cook in the oven.

STEP 4: ASSEMBLE THE CASSEROLE

Transfer the seafood mixture into the prepared baking dish, spreading it out evenly.

Top with the shredded cheddar cheese, then sprinkle the breadcrumbs (if using) evenly over the top. This will give the casserole a golden, crispy finish.

STEP 5: BAKE THE CASSEROLE

Place the casserole in the preheated oven and bake for 20-25 minutes, or until the cheese is melted and bubbly, and the top is golden brown.

If you like a crispier topping, you can place the casserole under the broiler for the last 1-2 minutes—just be sure to watch it closely to avoid burning.

STEP 6: GARNISH AND SERVE

Once the casserole is done, remove it from the oven and let it rest for a few minutes. Garnish with freshly chopped parsley for a pop of color and a squeeze of lemon juice for a bit of brightness.

How to Serve

With Rice
Seafood casserole pairs wonderfully with a side of rice. The creamy sauce soaks into the rice, making every bite just as flavorful as the casserole itself. Choose white rice, brown rice, or even wild rice for a more earthy flavor.

With Garlic Bread
For the ultimate indulgent meal, serve the casserole with garlic bread. The crispy, buttery bread is perfect for dipping into the rich, creamy sauce.

With Roasted Vegetables
To add some extra nutrition and balance the richness of the casserole, serve it with roasted vegetables. Roasted asparagus, Brussels sprouts, or a medley of root vegetables are excellent options.

With a Green Salad
A simple green salad with a light vinaigrette will provide a refreshing contrast to the creamy casserole. Consider adding some arugula, spinach, or mixed greens for extra flavor.

Additional Tips

1. Choose Fresh or Frozen Seafood: Whether you use fresh or frozen seafood is up to you, but ensure it’s high-quality. Frozen seafood works perfectly in casseroles, especially when you’re trying to make this dish more affordable.
2. Customize the Seafood: Feel free to swap out any of the seafood for what’s available in your area. Clams, lobster, or even mussels would work wonderfully in this dish.
3. Make it Ahead of Time: You can assemble the casserole ahead of time and store it in the fridge until you’re ready to bake it. Just add a few extra minutes to the baking time if it’s coming straight from the fridge.
4. Make it Gluten-Free: Use gluten-free breadcrumbs or omit them entirely if you prefer. You can also use cornstarch or a gluten-free flour blend for the sauce.
5. Adjust the Cheese: If cheddar isn’t your favorite, feel free to use a blend of mozzarella, Gruyère, or Parmesan for a different flavor.
