This delightful Christmas seafood casserole brings the flavors of the ocean to your holiday table. Combining succulent shrimp and rich crab meat with a creamy, cheesy sauce, this dish is topped with buttery breadcrumbs for a satisfying crunch. Perfect for a festive gathering, it's sure to impress your guests and become a new holiday favorite.
While most of the ingredients in this recipe are common, you might need to visit the seafood section for fresh shrimp and lump crab meat. Ensure the shrimp are peeled and deveined for convenience.

Ingredients For Christmas Seafood Casserole
Shrimp: Peeled and deveined, these provide a tender and juicy texture to the casserole.
Crab meat: Lump crab meat adds a rich, sweet flavor and delicate texture.
Heavy cream: This creates a creamy base for the casserole, adding richness and depth.
Parmesan cheese: Grated parmesan brings a nutty, salty flavor that complements the seafood.
Breadcrumbs: Mixed with melted butter, they form a crispy, golden topping.
Butter: Melted and mixed with breadcrumbs to create a crunchy topping.
Salt: Enhances the overall flavor of the dish.
Black pepper: Adds a hint of spice and balances the richness.
Garlic powder: Infuses the casserole with a subtle garlic flavor.
Technique Tip for This Seafood Casserole
When preparing the shrimp and crab meat, ensure they are thoroughly dried with paper towels before mixing them with the heavy cream and parmesan cheese. This helps to prevent excess moisture from diluting the casserole and ensures a creamy, rich texture. Additionally, when mixing the breadcrumbs with the melted butter, make sure every crumb is evenly coated. This will create a perfectly golden and crispy topping that contrasts beautifully with the creamy seafood filling.
