Step‑by‑Step Instructions for New England Seafood Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This initial step is crucial as it allows for even cooking of the New England Seafood Casserole, ensuring the seafood is perfectly tender and the topping gets beautifully golden. While the oven heats up, you can prepare the seafood, so gear up for multitasking!

Step 2: Prepare the Seafood
Rinse and pat dry the shrimp, scallops, and fish to remove excess moisture, preventing a watery casserole. Next, season the seafood lightly with a pinch of salt and arrange them in a 9×13 inch baking dish. This step sets the foundation for your casserole, letting the natural flavors shine through while they cook.

Step 3: Make the Roux
In a heavy skillet, melt 4 tablespoons of unsalted butter over medium heat. Once melted, add the shallots and sauté for about 3 minutes until translucent. Stir in minced garlic and cook for an additional minute, then whisk in the flour to create a blonde roux. Cook for 2 minutes, stirring constantly, to remove the raw flour taste while developing a rich base.

Step 4: Create the Sauce
Gradually whisk in ½ cup of dry sherry, making sure to scrape any bits from the skillet for extra flavor. After incorporated, slowly add 1½ cups of heavy cream along with 1 teaspoon of Old Bay seasoning. Let the mixture simmer for 3-5 minutes until it thickens to a luscious sauce. Stir in ½ cup of freshly grated Parmesan cheese until melted for an irresistible richness.

Step 5: Combine Seafood and Sauce
Gently fold the raw seafood into the creamy sauce, ensuring each piece is evenly coated. This delicate mixing helps retain the shape and tenderness of the seafood, which is essential for a delightful bite. Once combined, pour everything into the prepared baking dish, spreading it evenly for uniform cooking.

Step 6: Prepare the Topping
In a separate bowl, crush the Ritz crackers and combine them with 6 tablespoons of melted butter, 2 tablespoons of fresh parsley, and ¼ teaspoon of smoked paprika. This mixture will create a deliciously crunchy topping. Sprinkle it generously over the seafood mixture, ensuring an even layer that will bake beautifully.

Step 7: Bake the Casserole
Place the baking dish in the preheated oven and bake for 20-25 minutes. Keep an eye on it as the seafood should turn opaque and the topping become golden and crispy. The rich aroma of your New England Seafood Casserole will fill your kitchen, indicating it’s almost time to savor!

Step 8: Serve and Enjoy
Once baked to perfection, remove the casserole from the oven and let it cool slightly. Garnish with extra fresh parsley for a pop of color and serve warm. This enchanting dish brings the ocean’s flavors to your table, making it an unforgettable centerpiece for any meal.
