Why This Baked Seafood Casserole Is a Crowd-Pleaser

The combination of ocean-fresh seafood with a blend of creamy cheeses makes each forkful irresistible. It’s easy enough for a weeknight dinner, yet elegant enough to shine at festive gatherings or holiday celebrations.
Crafting the Perfect Cheesy Sauce
The creamy cheese sauce is the backbone of this casserole. Start by sautéing aromatics like garlic and shallot, then whisk in cream and just the right mix of shredded cheeses (cheddar and Gruyère work beautifully). Let everything bubble gently, and finish with a few dashes of lemon juice for brightness. The sauce should be velvety and ready to drape across your seafood mix—coating everything in smooth, savory perfection.
Building Your Seafood Casserole Layers
Layering is where the magic happens. Gently fold your seafood into the cheese sauce, then spoon the mixture into a casserole dish. For that classic finish, sprinkle on a generous topping of breadcrumbs tossed with a bit of melted butter and more cheese. Bake until the top is golden and bubbling, and you’ll unveil a show-stopping dish that’s ready to be served straight from the oven.
