Classic Way to Make Shrimp and Crab Casserole

Classic Way to Make Shrimp and Crab Casserole
1

Prepare the Oven

Heat your oven to 350°F. Grab a casserole dish and give it a quick spray with cooking spray or rub it with butter to prevent sticking.

2

Cook the Shrimp

Warm up a skillet with a splash of olive oil. Toss in 1 lb of peeled and deveined shrimp, cooking until they just turn pink. This usually takes about 2-3 minutes. Set the cooked shrimp aside to cool slightly.

3

Prep the Seafood

Chop 1 cup of imitation or fresh lump crab meat into bite-sized pieces. Make sure the pieces are small enough to mix evenly throughout the casserole.

4

Create the Creamy Base

Grab a large mixing bowl and combine the following:

  • 1 cup sour cream
  • 1/2 cup mayonnaise
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • 1/2 teaspoon paprika
  • 1/2 teaspoon black pepper
  • 1/4 teaspoon salt

Whisk these ingredients until they’re smooth and well blended.

5

Add the Cheese

Stir in your cheeses:

  • 1 1/2 cups shredded cheddar cheese
  • 1/2 cup mozzarella or Monterey Jack cheese

Mix until the cheese is evenly distributed throughout the creamy base.

6

Combine the Seafood

Gently fold in the cooked shrimp and chopped crab meat. Sprinkle in:

  • 2 chopped green onions
  • 1 tablespoon fresh parsley (if using)

Make sure everything gets a nice coating of the creamy mixture.

7

Prepare the Topping

If you want a crunchy top, mix:

  • 1/2 cup breadcrumbs
  • 1 tablespoon melted butter
8

Assemble and Bake

Pour the seafood mixture into your prepared casserole dish. If using, sprinkle the breadcrumb mixture evenly over the top. Slide the dish into the 350°F oven and bake for 25-30 minutes. You’re looking for a golden, bubbly top.

9

Finishing Touches

Pull the casserole out of the oven and let it rest for 5-10 minutes. This helps it set up and makes serving easier. If you’re feeling fancy, sprinkle a bit of extra paprika on top for some color.

Helpful Cooking Notes for Shrimp And Crab Casserole

  • Thaw frozen shrimp completely and pat dry to prevent watery casserole texture.
  • Grate cheeses fresh for smoother melting and richer flavor throughout your dish.
  • Let your creamy base sit for 10 minutes before mixing in seafood to help flavors develop deeper.
  • Toast breadcrumbs in a dry pan before sprinkling on top for extra golden, crispy texture.
  • Let casserole rest 5-7 minutes after baking so it sets and cuts more cleanly on your plate.

Creative Variations For Shrimp And Crab Casserole

  • Dairy-Free Seafood Casserole: Swap sour cream and mayo with coconut cream, use nutritional yeast instead of cheese, and ensure all ingredients are dairy-free for those with lactose sensitivities.
  • Low-Carb Ocean Bake: Replace breadcrumbs with crushed pork rinds or almond flour, reducing carbohydrate content while keeping the delicious seafood flavor intact.
  • Spicy Cajun Seafood Blend: Add cayenne pepper, Cajun seasoning, and diced bell peppers to kick up the heat and bring a zesty New Orleans-style profile to your casserole.
  • Mediterranean Seafood Twist: Incorporate feta cheese, chopped olives, and fresh dill, transforming the dish with bright Mediterranean flavors that complement the seafood perfectly.

Best Serving Options For Shrimp And Crab Casserole

  • Serve Warmly: Scoop this creamy seafood casserole directly from the baking dish onto warm plates, making sure everyone gets a generous portion of those tender shrimp and crab chunks.
  • Perfect Side Companions: Pair this rich dish with a light, crisp green salad or some steamed asparagus to balance the casserole’s creamy texture and add a fresh vegetable element to your meal.
  • Wine Selection: Choose a crisp white wine like Sauvignon Blanc or Pinot Grigio that will complement the seafood’s delicate flavors without overpowering the creamy sauce.
  • Bread Basket: Serve with crusty French bread or garlic toast to help soak up the delicious sauce and give your guests something extra to enjoy alongside the casserole.

Smart Storage Tips For Shrimp And Crab Casserole

  • After cooking, store leftovers in an airtight container in the refrigerator, where they’ll keep fresh for 2-3 days.
  • Freeze your casserole before baking by wrapping tightly in plastic wrap and aluminum foil, which helps preserve the seafood’s delicate flavor for up to one month.
  • When reheating, warm gently in the oven at 325°F to prevent the seafood from becoming tough and rubbery, which can happen in the microwave.
  • Transfer cold casserole from the fridge to the counter for about 15 minutes before reheating to help it warm more evenly and maintain its creamy texture.
