Ingredients for Seafood Casserole Recipe Paula Deen

This Southern seafood casserole relies on premium crab and shrimp elevated by a velvety roux-based sauce and crispy cracker topping.

The seafood quality determines this dish’s success. Lump crabmeat from the refrigerated section (not canned) provides superior texture—Whole Foods or Fresh Market typically carry excellent options. For shrimp, opt for wild-caught Gulf shrimp (16/20 count) for optimal flavor and texture. The butter and cream form the foundation of Paula’s signature richness—Plugrá butter and organic heavy cream yield the most luxurious results. Avoid pre-shredded cheese, as its anti-caking agents prevent proper melting.

Substitutions must maintain the dish’s decadent character. Imitation crab cannot replicate the delicate flavor of real lump crabmeat. For a lighter version, half-and-half may replace the cream, though the sauce will be less velvety. Panko breadcrumbs can stand in for Ritz crackers, but the signature buttery flavor will differ. The Worcestershire sauce is essential for umami depth—Annie’s brand offers an anchovy-free version if preferred. Fresh herbs like parsley or chives make excellent garnishes (add 2 tbsp chopped).

Assemble the casserole just before baking to preserve the cracker topping’s crunch. Leftovers reheat well in a 350°F oven for 15 minutes, covered with foil. The casserole keeps for 3 days refrigerated or 2 months frozen (thaw overnight before reheating). For make-ahead preparation, complete all steps except baking, then refrigerate up to 24 hours before the final bake. Always use a light hand when folding in the seafood to maintain its delicate texture.

Step-by-Step Instructions for Seafood Casserole

This method ensures perfectly balanced flavors with a golden, buttery crust and creamy seafood filling.

Step 1: Prepare the Seafood and Aromatics

Begin by preheating your oven to 375°F. I recommend using a 3-quart baking dish for this recipe to ensure even cooking. Pat the 1 lb lump crabmeat dry with paper towels to remove excess moisture—this prevents the casserole from becoming watery during baking.

In a large skillet, melt 2 tablespoons of the 0.5 cup unsalted butter over medium heat. Add the 1 lb large shrimp and sauté for 2-3 minutes until they turn opaque and pink. Remove the shrimp from the skillet and set aside. In the same skillet, add the finely diced yellow onion and small-diced celery stalks, cooking for 5-6 minutes until softened. Stir in the minced garlic cloves and cook for an additional 30 seconds until fragrant.

Step 2: Create the Creamy Roux Base

To the skillet with the aromatics, add the remaining 0.5 cup unsalted butter and melt over medium-low heat. Whisk in the 0.33 cup all-purpose flour to form a roux, cooking for 2-3 minutes until it reaches a light golden color and the raw flour scent dissipates. This step is crucial for eliminating any starchy taste.

Gradually pour in the 1.5 cups heavy cream and 1 cup whole milk, whisking constantly to prevent lumps from forming. Increase the heat to medium and continue whisking until the mixture thickens enough to coat the back of a spoon, about 5-7 minutes. Stir in the 1 tbsp Worcestershire sauce, 0.5 tsp hot sauce, 1.5 tsp kosher salt, and 0.5 tsp freshly ground black pepper, then remove the skillet from heat.

Step 3: Assemble the Casserole Layers

In a large mixing bowl, gently fold the cooked shrimp and 1 lb lump crabmeat into the cream sauce, being careful not to break up the crabmeat too much. Transfer this mixture to your prepared baking dish, spreading it evenly. Sprinkle the 1.5 cups sharp cheddar cheese uniformly over the top—this will create a rich, melty layer beneath the cracker crust.

Place the 24 pieces Ritz crackers in a sealed plastic bag and crush them into coarse crumbs using a rolling pin or your hands. Sprinkle these crumbs evenly over the cheese layer, pressing down lightly to help them adhere. The crackers will absorb some moisture during baking while maintaining their buttery crunch.

Step 4: Bake to Golden Perfection

Bake the casserole uncovered on the middle oven rack for 25-30 minutes, or until the top is deep golden brown and the edges are bubbling vigorously. You’ll know it’s done when the cracker topping is crisp and the filling appears set with no visible liquid on the surface.

For even browning, I recommend rotating the dish 180 degrees halfway through the baking time. If the top begins to brown too quickly before the casserole is fully cooked, tent it loosely with aluminum foil. The internal temperature should reach 165°F when tested in the center with an instant-read thermometer.

Step 5: Rest and Serve

Remove the casserole from the oven and let it rest for 10 minutes before serving. This resting period allows the filling to set properly, making it easier to serve neat portions. The casserole will continue to cook slightly from residual heat during this time.

Use a sharp knife to cut into squares, ensuring each serving contains both the creamy seafood filling and the crispy cracker topping. Serve immediately while hot, as the contrast between the warm, velvety interior and the buttery, crunchy topping is at its best. This dish pairs particularly well with a simple green salad or steamed vegetables to balance its richness.

Pro Cooking Tips for seafood casserole recipe paula deen

Roux Perfection Tips

The roux is the backbone of this casserole’s velvety texture. Cook it over medium-low heat for exactly 2-3 minutes until it reaches a light peanut butter color—this eliminates the raw flour taste while avoiding over-browning. I use a flat-bottomed whisk for constant stirring, which prevents lumps better than a spoon. 🌡️

Seafood Handling Secrets

Pat the lump crabmeat and shrimp completely dry before adding to the sauce—excess moisture creates a watery filling. I lay them on paper towels for 5 minutes before cooking. For shrimp, cook just until they turn opaque pink (2-3 minutes max) to prevent rubbery texture in the final dish.

Layering for Texture

Spread the seafood mixture evenly in the dish, then sprinkle sharp cheddar first—this creates a melty barrier between filling and crackers. Crush Ritz crackers into pea-sized pieces (not powder) for optimal crunch. Press lightly so they adhere but don’t compact, which would make the topping soggy.

Baking Mastery

Bake at 375°F on the middle rack for even heat distribution. Rotate the dish 180 degrees halfway through for uniform browning. The casserole is done when the center reaches 165°F and the edges bubble vigorously—this ensures the filling is fully set without overcooking the seafood.

Resting is Crucial

Let the casserole rest for 10 minutes after baking—this allows the sauce to thicken slightly for cleaner slices. I tent it loosely with foil to keep warm while preventing the topping from softening. The residual heat will finish cooking the center perfectly.

Serving Pro Tips

Use a sharp chef’s knife dipped in hot water to cut clean portions. Serve immediately with lemon wedges for brightness and hot sauce on the side for those who want heat. The contrast of creamy filling and crisp topping is best enjoyed fresh from the oven. 💛
