It combines the rich flavors of the ocean with creamy textures, making it a favorite among both seafood lovers and skeptics. This dish is not only satisfying but also versatile, allowing for various seafood blends and seasonings to suit your taste.
Using fresh seafood, this casserole showcases the briny sweetness of fish and shellfish against a backdrop of creamy sauce and crunchy toppings. It’s perfect for those chilly evenings or special occasions where you want to impress without spending all day in the kitchen.
Ingredients
- 1 pound mixed seafood (shrimp, scallops, fish)
The central ingredient, mixed seafood, provides a variety of flavors and textures. Shrimp adds a firm bite, scallops contribute sweetness, and fish creates a light and flaky base. - 1 cup cooked rice
Rice acts as a hearty base that absorbs the flavors of the seafood and sauce, creating a filling dish. It also helps to bind the ingredients together, ensuring every bite is delicious. - 1 small onion, diced
Onion brings a savory sweetness that enhances the overall flavor profile. When sautéed, it softens and caramelizes, adding depth to the casserole. - 2 cloves garlic, minced
Garlic adds an aromatic punch and enhances the seafood's flavors. Its boldness balances the richness of the sauce, drawing out the best in all the ingredients. - 1 cup heavy cream
Heavy cream provides a velvety richness that coats the seafood and rice, turning the casserole into a luxurious dish. It also adds moisture, preventing the casserole from drying out in the oven. - 1 cup shredded cheese (cheddar or Gruyère)
Cheese adds a creamy texture and a delightful flavor that complements the seafood. It also forms a golden crust on top, adding visually appealing contrast. - 1/2 cup breadcrumbs
Breadcrumbs serve as a crunchy topping, creating textural contrast with the creamy filling. They can be seasoned to elevate the dish's taste, providing a satisfying crunch. - 2 tablespoons olive oil
Olive oil is used for sautéing the onions and garlic, adding healthy fats and flavor. It is also essential for toasting the breadcrumbs for a crispy finish. - Salt and pepper to taste
Seasoning with salt and pepper enhances all flavors in the casserole, ensuring each ingredient shines. Adjust according to your preference for a balanced taste.
Directions & Preparation
Step 1: Preheat the oven to 375°F (190°C).
Preheating the oven is essential to ensure the casserole cooks evenly from the start. A hot oven creates a golden crust on top and helps the ingredients meld together seamlessly.
Step 2: In a skillet, heat the olive oil over medium heat. Add the diced onion and sauté until translucent, about 5 minutes. Stir in the minced garlic and sauté for an additional minute.
Sautéing the onion first brings out its natural sweetness, which forms a flavor base for the casserole. Adding garlic at the end ensures it maintains its robust flavor without burning.
Step 3: Mix the seafood into the skillet with the onions and garlic. Cook for 3-4 minutes until just cooked through, then remove from heat.
Cooking the seafood in the skillet allows it to absorb the flavors of the onion and garlic. This step also prevents the seafood from overcooking later in the oven.
Step 4: In a large mixing bowl, combine the cooked rice, heavy cream, half of the cheese, and salt and pepper. Mix well.
Combining these ingredients in a bowl ensures an even distribution of flavors. The heavy cream will moisten the rice, and the cheese will add flavor and creaminess.
Step 5: Fold the sautéed seafood mixture into the rice mixture until well combined.
Gently folding the seafood into the rice mixture ensures even distribution without breaking up the delicate pieces of seafood, maintaining their texture.
Step 6: Transfer the mixture into a greased baking dish, spreading it out evenly.
Evenly spreading the mixture promotes uniform cooking. Greasing the baking dish helps prevent sticking, making it easier to serve.
Step 7: Sprinkle the remaining cheese and breadcrumbs evenly on top.
Adding breadcrumbs creates a satisfying crunch and helps to form a golden crust during baking. The cheese will melt and enhance the flavor, making the top deliciously gooey.
Step 8: Bake in the preheated oven for 25-30 minutes, or until the top is golden and bubbly.
Baking is crucial for melding the flavors together and ensuring the casserole is hot throughout. A golden top indicates that it’s perfectly cooked and ready to serve.
Step 9: Let the casserole cool for a few minutes before serving.
Allowing the casserole to cool slightly helps it set, making it easier to serve and ensuring that it retains its shape on the plate.

Elevating Flavors with Fresh Herbs
To enhance the freshness of your baked seafood casserole, consider adding a blend of fresh herbs like parsley, dill, or chives. These herbs not only contribute to the overall flavor but also provide a beautiful green contrast against the creamy base. Adding herbs just before baking helps retain their vibrant colors and aromas, boosting the dish’s appeal.
Choosing Seafood Wisely
The choice of seafood can greatly influence the final taste of your casserole. Opt for a mix of sustainable seafood, focusing on what's fresh in your market. While shrimp, scallops, and a firm white fish like cod or tilapia are popular choices, feel free to experiment with crab meat or mussels for a unique twist.
Crunchy Topping Variations
The breadcrumb topping can be enhanced beyond just plain crumbs. Try mixing in some grated parmesan for extra flavor or using panko breadcrumbs for a lighter, crunchier texture. A sprinkle of paprika or seasoning on top before baking can add not just flavor but also a beautiful color, elevating the entire presentation.
FAQs
What can I do if my casserole is too runny?
If your casserole is too runny, try adding a bit more rice or breadcrumbs to thicken it. You can also bake it a little longer to help evaporate excess moisture.

What if I find the casserole too bland?

Is there a way to incorporate vegetables in this dish?
Absolutely! Adding vegetables like spinach, bell peppers, or peas can enhance both the nutrition and flavor of your casserole. Just sauté them briefly with the onions.
How do I ensure the seafood is not overcooked?
To prevent overcooking, make sure to cook the seafood just until opaque in the skillet before transferring it to the casserole. It will continue cooking in the oven.
