Step‑by‑Step Instructions for Seafood Casserole Creamy Step 1: Preheat and Prepare Begin by preheating your oven to 375°F (190°C). While the oven heats, generously grease a 3-quart casserole dish with butter or cooking spray to prevent sticking. This will ensure your creamy seafood casserole lifts easily and has a lovely texture once baked. Step 2: Sauté the Vegetables In a large skillet, melt 2 tablespoons of unsalted butter over medium heat. Add finely chopped onion, celery, diced carrots, and sliced mushrooms. Sauté the mixture for about 6 minutes, stirring frequently, until the vegetables are softened and fragrant. This forms a delicious aromatic base for your seafood casserole. Step 3: Add Garlic and Flour Stir in minced garlic, cooking for an additional minute until it’s golden and aromatic. Next, sprinkle 1/4 cup of all-purpose flour over the vegetable mixture, stirring well to coat. This step will help thicken your sauce, creating that creamy texture we crave in a seafood casserole. Step 4: Make the Creamy Sauce Gradually whisk in 2 cups of seafood stock and 1 cup of heavy cream, stirring continuously. Increase the heat slightly and bring the sauce to a simmer, allowing it to thicken for about 5-7 minutes. You’ll notice the sauce transforming into a luscious mixture that perfectly coats all the veggies. Step 5: Fold in the Seafood Gently fold in your selection of seafood, including shrimp, scallops, white fish, and crab meat. Cook for an additional 2-3 minutes, just until the seafood turns opaque. Season the mixture with salt, pepper, and a sprinkle of Old Bay seasoning to enhance that classic seafood flavor. Step 6: Transfer and Top Pour the rich seafood mixture into your prepared casserole dish, spreading it out evenly. In a separate bowl, mix together 1 cup of breadcrumbs, 1/2 cup of grated Parmesan cheese, and 1 tablespoon of chopped fresh parsley. Sprinkle this delicious topping evenly over the casserole, adding an irresistible crunch. Step 7: Bake to Perfection Place the casserole in the preheated oven and bake for 20-25 minutes. Keep an eye out for the topping to turn golden brown and for the filling to bubble. When you see those signs, it’s time to pull your creamy seafood casserole out of the oven to serve!
