Ingredients You’ll Need
This recipe keeps things straightforward but delivers on every front — flavor, texture, and visual appeal. Each ingredient plays a crucial role, whether it’s the buttery cream sauce that envelops the seafood, the zesty lemon juice that lifts the richness, or the Parmesan cheese that adds savory depth.
- Shrimp (1 pound): Fresh or frozen, peeled and deveined for tender, juicy bites of sweetness.
- Scallops (1 pound): The star seafood that offers a delicate, buttery flavor and lovely texture.
- Crab Meat (1 cup): Fresh or imitation crab gives the casserole a luscious, briny twist; feel free to omit as you like.
- Unsalted Butter (4 tablespoons): Forms the rich base of the creamy sauce and enhances the breadcrumb topping’s golden crispiness.
- All-Purpose Flour (1/4 cup): Helps thicken the sauce; gluten-free flour also works well here.
- Milk (1 cup): Adds mellow milky notes; for a lighter twist, non-dairy milk is a fantastic alternative.
- Heavy Cream (1 cup): Infuses the dish with luscious richness; half-and-half works too if you prefer a lighter sauce.
- Garlic (2 cloves, minced): Brings a savory aroma and a subtle bite that awakens the seafood flavors.
- Lemon Juice (2 tablespoons): Balances the creaminess with a bright, zesty spark.
- Dijon Mustard (1 tablespoon): Adds a subtle tang that elevates the sauce’s complexity.

How to Make Baked Seafood Casserole: Creamy Comfort for Cozy Nights Recipe
Step 1: Prepare the Oven and Baking Dish
Start by preheating your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish to ensure your casserole doesn’t stick, setting you up for an easy cleanup later on.
Step 2: Sauté the Garlic and Seafood
Heat 2 tablespoons of olive oil in a large skillet over medium heat. Toss in the minced garlic and sauté until fragrant—about one minute. This small step unlocks a flood of savory aroma that will infuse the seafood. Add shrimp and scallops along with fresh lemon juice, paprika, salt, and pepper. Cook these until just done — about two to three minutes — so they remain tender and juicy without becoming rubbery.
Step 3: Whisk Together the Cream Sauce Base
In a medium saucepan, melt the unsalted butter over medium heat. Add the flour and whisk continuously for one to two minutes to cook out the raw flour taste. Slowly pour in the milk and heavy cream while whisking, then cook for three to four minutes, stirring constantly until the sauce thickens beautifully and can coat the back of your spoon.
Step 4: Build the Flavor-Packed Sauce
To your creamy base, stir in the grated Parmesan cheese, Dijon mustard, and Old Bay seasoning. This combo provides rich layers of umami, subtle tanginess, and that distinctive coastal seasoning that defines the Baked Seafood Casserole: Creamy Comfort for Cozy Nights Recipe.
Step 5: Combine Seafood and Sauce
Fold your sautéed shrimp and scallops, along with the crab meat, into the luscious cream sauce, ensuring every piece is lovingly coated with that rich, creamy goodness. This melding of flavors is what makes this casserole so irresistibly satisfying.
Step 6: Prepare the Crispy Topping
Mix together the panko breadcrumbs, melted butter, and remaining Parmesan cheese in a small bowl. This mixture is the secret to that golden, crunchy layer that makes this dish a real standout at the dinner table.
Step 7: Assemble and Bake
Transfer the creamy seafood mixture into your prepared baking dish, then generously sprinkle the breadcrumb topping evenly over the surface. Pop it into the oven baked uncovered for 20-25 minutes, until the sauce is bubbling and the top is beautifully golden brown.
Step 8: Garnish and Serve
Allow the casserole to cool for about five minutes before garnishing with freshly chopped parsley. This not only adds a pop of color but a fresh note to each luscious, creamy bite.
How to Serve Baked Seafood Casserole: Creamy Comfort for Cozy Nights Recipe
Garnishes
Fresh parsley is a classic and easy garnish, but you can also consider a sprinkle of lemon zest or a few thinly sliced green onions. These simple touches brighten the rich flavors and add a bit of visual flair, making each serving feel extra special.
Side Dishes
This dish pairs wonderfully with light, crisp sides that provide contrast to its richness. Consider a fresh garden salad with a zingy vinaigrette, roasted seasonal vegetables, or even a crusty artisan bread perfect for sopping up that creamy sauce.
Creative Ways to Present
Why not serve individual portions in small ramekins for a charming presentation? Or layer the casserole atop mashed potatoes or creamy polenta for a cozy, comforting twist. A sprinkling of toasted nuts or a dash of smoked paprika on top can also add unexpected texture and smoky flavor highlights.
Make Ahead and Storage
Storing Leftovers
Your Baked Seafood Casserole: Creamy Comfort for Cozy Nights Recipe keeps beautifully in the fridge for up to three days. Store leftovers in an airtight container to preserve that creamy texture and seafood freshness. It’s a fantastic way to enjoy a fuss-free meal later in the week.
Freezing
If you want to save some for even longer, this casserole freezes remarkably well. Wrap it tightly with plastic wrap and foil or use a freezer-safe container. When frozen, it can last up to two months without sacrificing flavor or texture.
Reheating
To reheat, thaw overnight in the fridge if frozen. Warm the casserole in a 350°F (175°C) oven, covered loosely with foil to prevent over-browning, until heated through and bubbly. A few extra minutes without the foil at the end will help restore that crispy breadcrumb topping.
FAQs
Can I use other types of seafood in this casserole?
Absolutely! While shrimp, scallops, and crab are classic here, you can experiment with lobster, clams, or firm white fish. Just adjust the cooking times accordingly to prevent overcooking delicate seafood.
Is it possible to make this gluten-free?
Yes! Substitute the all-purpose flour with a gluten-free flour blend, and make sure to use gluten-free panko breadcrumbs. The creamy texture and crispy topping will still shine wonderfully.
Can I prepare parts of the casserole ahead of time?
You can prepare the seafood and sauce in advance and store them separately in the fridge for up to a day. Assemble and bake when ready to serve for the freshest taste and texture.
What if I don’t have Old Bay seasoning?
Mix equal parts paprika, celery salt, black pepper, and a pinch of cayenne to create a good substitute. This blend will capture that signature seafood spice that Old Bay provides.
Can I lighten this dish for a healthier option?
Certainly! Use non-dairy milk or half-and-half instead of heavy cream, reduce the butter slightly, and increase the amount of fresh herbs. These swaps keep the soul of the Baked Seafood Casserole: Creamy Comfort for Cozy Nights Recipe while making it a bit lighter.
