Why This Hearty Seafood Casserole is a Family Favorite

The secret to this casserole’s widespread appeal lies in its bold mix of tender seafood and hearty vegetables, all enveloped in a creamy sauce that binds everything together. The toasted breadcrumb topping adds irresistible texture, creating a complete meal that’s easy to portion and reheat—making it ideal for meal prepping and leftovers.

Building Flavors with Seafood and Vegetables

Selecting a combination of shrimp, scallops, and flaky white fish provides a spectrum of textures and tastes in every bite. Layering in vegetables like bell peppers, celery, and peas deepens the flavor and stretches the dish further, ensuring every serving is abundant and satisfying. A light white wine and a handful of fresh herbs add layers of complexity without overpowering the delicate seafood.

Assembling the Perfect Seafood Casserole

Begin by sautéing the vegetables to soften and build flavor. Gently fold in the seafood and pour a creamy, herbed sauce over the mixture before topping with buttery breadcrumbs. Baking transforms the casserole into a bubbling, golden masterpiece—ready to enjoy in under an hour from start to finish.

Instructions

1. Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish or similar casserole dish.
2. In a large skillet, melt 2 tablespoons of butter over medium heat. Add onion, celery, and bell pepper. Sauté for 4–5 minutes until just softened.
3. Stir in the shrimp, scallops, and fish. Cook for about 2–3 minutes, just until the seafood starts to turn opaque (do not overcook as it will finish baking in the oven). Stir in the peas. Remove mixture from skillet and spread evenly in the prepared casserole dish.
4. In the same skillet, sprinkle in the flour, stirring to form a paste. Gradually whisk in milk (and wine, if using), stirring constantly until a smooth, slightly thickened sauce forms, 3–4 minutes. Stir in parmesan cheese, salt, pepper, and parsley.
5. Pour the sauce evenly over the seafood and vegetables in the baking dish. Gently toss to combine.
6. In a small bowl, mix the panko breadcrumbs with the melted butter. Sprinkle evenly over the casserole.
7. Bake uncovered for 20–25 minutes until bubbly and the top is golden brown. Let rest for 5 minutes before serving. Serve with fresh lemon wedges and extra parsley if desired.
