Ingredients

Seafood & Sauce:

1 lb shrimp, peeled and deveined

1 lb crab meat (lump or claw)

1 tablespoon olive oil

2 cloves garlic, minced

1 small onion, finely chopped

Béchamel Sauce:

1/2 cup butter

1/2 cup all-purpose flour

4 cups whole milk (warm)

1/2 teaspoon salt

1/4 teaspoon black pepper

1/4 teaspoon nutmeg (optional)

1/2 cup grated Parmesan cheese

Cheese & Pasta:

2 cups shredded mozzarella cheese

1 cup ricotta cheese

9–12 lasagna noodles (regular or no-boil)

To Finish:

Fresh parsley, chopped (for garnish)

Instructions

Prep Noodles: If using regular noodles, boil per package directions, then drain and set aside.

Cook Seafood: Heat olive oil in a skillet over medium heat. Sauté onion and garlic until soft. Add shrimp and cook 2–3 minutes until pink. Stir in crab and cook 1 minute. Remove from heat.

Make Béchamel: In a saucepan, melt butter over medium heat. Whisk in flour and cook 1–2 minutes. Gradually whisk in warm milk and stir until thickened (6–8 minutes). Season with salt, pepper, and nutmeg. Stir in Parmesan.

Assemble Lasagna: Spread a thin layer of béchamel in a 9×13-inch baking dish. Layer noodles, seafood mixture, béchamel, dollops of ricotta, and mozzarella. Repeat layers 2 more times. Finish with noodles, remaining béchamel, and mozzarella.

Bake: Cover with foil and bake at 375°F (190°C) for 25 minutes. Uncover and bake another 15–20 minutes until golden and bubbly.

Rest & Serve: Let lasagna rest 10 minutes. Garnish with chopped parsley before serving.

Notes

Resting helps the layers set and enhances flavor.

Add sautéed spinach or zucchini for freshness.

A pinch of red pepper flakes adds a spicy twist.
