How to Make Seafood Lasagna with Shrimp and Crab

Step 1: Prepare the Seafood

First, sauté the shrimp and crab gently with garlic and onions until just cooked through, allowing the flavors to blend while keeping the seafood tender and juicy.

Step 2: Make the Béchamel Sauce

Whisk together butter, flour, and warm milk over medium heat until thick and creamy, seasoning with salt, pepper, and a pinch of nutmeg for warmth.

Step 3: Cook the Lasagna Noodles

If using regular noodles, boil them until al dente, then drain and separate to prevent sticking—no-boil noodles simply need to be softened slightly before layering.

Step 4: Assemble the Layers

Spread a thin layer of béchamel sauce on the bottom of your baking dish, then layer noodles, seafood mixture, béchamel, and a sprinkle of mozzarella and Parmesan cheese; repeat until all ingredients are used, finishing with a generous topping of cheese.

Step 5: Bake to Perfection

Bake in a preheated oven at 375°F (190°C) for about 30 to 40 minutes, or until the top is golden and bubbly, signaling a perfectly cooked seafood lasagna ready to serve.

Pro Tips for Making Seafood Lasagna with Shrimp and Crab

• Use fresh or high-quality frozen seafood: It makes a significant difference in flavor and texture.
• Don’t overcook the seafood: Sauté just until opaque to keep it tender inside the lasagna.
• Prepare béchamel with patience: Stir constantly to avoid lumps and achieve the perfect creamy consistency.
• Let it rest after baking: Allow the lasagna to cool for 10-15 minutes before slicing to maintain beautiful layers.
• Add a splash of white wine: It brightens the seafood flavor in the sauce without overpowering the dish.

How to Serve Seafood Lasagna with Shrimp and Crab

Garnishes

Freshly chopped parsley or basil sprinkled on top adds a bright, fresh contrast to the rich layers, while a light drizzle of lemon-infused olive oil can enhance the seafood notes beautifully.
