To prepare this comforting yet elegant Seafood Lasagna with Shrimp & Crab, you’ll need a mix of seafood, dairy, pasta, and simple aromatics. Each ingredient plays an important role in creating layers of flavor and texture.

Seafood

• 1 tablespoon olive oil
• 1 tablespoon butter
• 1 pound raw shrimp, peeled, deveined, and chopped into bite-sized pieces
• 8 ounces lump crab meat (fresh or pasteurized), picked over for shells

Shrimp and crab provide the heart of this lasagna. The shrimp adds structure and richness, while the crab brings sweetness and a soft, luxurious texture.

Aromatics and Base Flavor

• 1 small onion, finely chopped
• 3 cloves garlic, minced
• 1/4 teaspoon red pepper flakes (optional, for a mild kick)
• Salt and black pepper, to taste

These simple ingredients build a savory base that enhances the seafood without overpowering it.

Sauce

• 4 tablespoons butter
• 4 tablespoons all-purpose flour
• 3 cups milk (warm)
• 1 cup heavy cream
• 1 teaspoon salt
• 1/2 teaspoon white or black pepper
• 1/4 teaspoon nutmeg

This creamy white sauce forms the backbone of the lasagna. It keeps the dish moist, rich, and cohesive.

Cheese

• 1 1/2 cups ricotta cheese
• 1 cup shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1 large egg

The cheese mixture adds creaminess and structure, while Parmesan contributes a salty, nutty bite.

Pasta and Finishing

• 9–12 lasagna noodles, cooked according to package directions
• 2 tablespoons chopped fresh parsley
• Optional: extra mozzarella or Parmesan for topping
