How to Make Crab and Shrimp Casserole Recipe
Step 1: Prepare the Baking Dish and Vegetables
Start by preheating your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish to ensure the casserole won’t stick. While the oven warms up, sauté the finely chopped onion, bell pepper, celery, and minced garlic in butter over medium heat. Cook them just until they soften and become fragrant, which releases their natural sweetness and forms a tasty base for the sauce.
Step 2: Make the Creamy Sauce
Once your veggies are tender, sprinkle the all-purpose flour over them and stir well to coat. This creates a roux that will thicken the sauce. Gradually whisk in the milk and chicken broth, stirring constantly to avoid lumps. Continue cooking and stirring until the mixture thickens into a smooth, creamy sauce that perfectly envelops your vegetables.
Step 3: Season and Add Seafood
Now it’s time for the magic! Season the sauce with Old Bay seasoning, salt, and freshly cracked pepper to bring out all those rich ocean flavors. Gently fold in the lump crabmeat and peeled shrimp, taking care not to break up the delicate crab. This mix of creamy sauce, tender seafood, and softened veggies is what makes this Crab and Shrimp Casserole Recipe truly irresistible.
Step 4: Assemble and Bake
Pour the luscious seafood mixture into your prepared baking dish, spreading it evenly. Sprinkle shredded cheddar cheese generously across the top, then finish with a layer of breadcrumbs for that classic golden crunch after baking. Slide the casserole into your preheated oven and bake for 25 to 30 minutes until it’s bubbly around the edges and the topping is beautifully browned.
Step 5: Garnish and Serve
When your casserole comes out of the oven, let it rest for a few minutes. Then sprinkle freshly chopped parsley on top to add a burst of color and a fresh, herbaceous note. Your Crab and Shrimp Casserole Recipe is ready to wow the taste buds!
How to Serve Crab and Shrimp Casserole Recipe
Garnishes
Keep garnishes simple but bright — a sprinkle of fresh parsley is classic, but you can also add a few lemon wedges on the side to give an extra zing that complements the seafood beautifully. A light drizzle of hot sauce or a dash of smoked paprika can introduce a subtle heat that wakes up the flavors in a wonderful way.
Side Dishes
This casserole pairs wonderfully with crisp green salads, roasted asparagus, or buttery garlic bread. Offering light and fresh sides lets the rich casserole shine while balancing your meal with a variety of textures and flavors. A chilled glass of crisp white wine or sparkling water with lemon would complete the experience.
Creative Ways to Present
For a festive occasion, serve the Crab and Shrimp Casserole Recipe in individual ramekins or small oven-safe dishes, topped with a sprinkle of paprika or a sliver of fresh chive. You can also spoon it over toasted French bread slices for an open-faced, indulgent appetizer. Consider adding a side of avocado slices or a tangy mango salsa for a tropical twist that’s sure to surprise and delight.
Make Ahead and Storage
Storing Leftovers
If you have leftovers, transfer them to an airtight container and refrigerate for up to three days. The flavors meld beautifully overnight, making it just as delicious, if not better, the next day. Just make sure to chill it promptly after serving to keep the seafood fresh.
Freezing
This Crab and Shrimp Casserole Recipe freezes well, making it perfect for meal prep or unexpected guests. Allow it to cool completely before wrapping tightly with plastic wrap and aluminum foil or using a freezer-safe container. It will keep well for up to two months in the freezer, ready to bring that cozy, seafood comfort on demand.
Reheating
To reheat, thaw frozen casserole overnight in the fridge if needed. Warm it gently in a 350°F (175°C) oven until heated through and bubbly again, about 20 minutes. This helps maintain the creamy texture and toasts the breadcrumb topping back to its original crispness. Avoid the microwave if you want to preserve that golden crust and evenly warmed interior.
FAQs
Can I use canned crabmeat instead of lump crab?
While fresh or lump crabmeat offers the best flavor and texture, canned crabmeat can be a convenient alternative. Just be sure to drain it well to avoid excess moisture in the casserole and choose the best quality you can find for optimal taste.
Is it possible to make this casserole spicy?
Absolutely! You can add a pinch of cayenne pepper or a dash of hot sauce to the sauce during cooking. Alternatively, sprinkle some red pepper flakes on top before baking to give your Crab and Shrimp Casserole Recipe a lively kick.
Can I substitute the shrimp with another type of seafood?
Yes, feel free to swap shrimp for scallops or chunks of firm white fish like cod. Just make sure to adjust the cooking time as needed, since some seafood cooks faster or slower than shrimp.
What can I use instead of Old Bay seasoning?
If you don’t have Old Bay, you can mix your own blend of paprika, celery salt, black pepper, cayenne, and dry mustard to capture a similar flavor profile. A pinch of thyme or oregano also enhances the seasoning without overpowering the seafood.
Is this Crab and Shrimp Casserole Recipe gluten-free?
As written, it contains all-purpose flour and breadcrumbs which have gluten. To make it gluten-free, substitute with a gluten-free flour blend and gluten-free breadcrumbs or crushed nuts for the topping. The flavors will still come through beautifully!
