Step-by-Step Instructions

1. Prepare the noodles and baking dish

Preheat oven to 375°F. Spray a 9×13-inch baking dish with nonstick cooking spray. Cook 12 lasagna noodles according to package directions until just al dente. Drain and lay flat on a lightly oiled sheet of foil to prevent sticking. Set aside.

2. Cook the shrimp

In a large skillet over medium-high heat, melt 1 tablespoon of butter. Add the roughly chopped shrimp and season with 1 teaspoon of Old Bay seasoning and a pinch of salt and pepper. Cook for 2–3 minutes, just until shrimp are pink and opaque. Do not overcook. Remove shrimp to a large bowl and set aside.

3. Warm the crab

Add the drained crab meat to the same pan and toss gently for 1 minute to warm through and absorb the drippings. Add crab meat to the bowl with the shrimp and set aside to cool slightly.

4. Make the white sauce

In the same skillet, melt 4 tablespoons of butter over medium heat. Add 4 cloves of minced garlic and cook for about 1 minute, stirring frequently, until fragrant. Whisk in 1/4 cup of all-purpose flour and let it cook and bubble for a full 1 minute, whisking constantly.

Slowly pour in 1 1/2 cups of low sodium chicken broth while whisking vigorously to eliminate any lumps. Pour in 1 1/2 cups of heavy cream. Bring to a gentle simmer and whisk continuously for 3–4 minutes until the sauce thickens. Season with salt and pepper to taste. Remove from heat.

5. Prepare the ricotta mixture

In a large bowl, combine 2 cups of whole milk ricotta, 4 oz cream cheese, 1 large egg, 1/4 cup Parmesan cheese, 1/2 teaspoon salt, and 1/4 teaspoon black pepper. Stir until smooth. Gently fold in shrimp and crab mixture.

This creamy filling is the heart of Seafood Lasagna with Shrimp and Crab.

6. Assemble the lasagna base

Spread about 1/2 cup of white sauce in the bottom of the prepared baking dish. Add 3–4 lasagna noodles over the sauce.

7. First layer

Spread half of the ricotta and seafood filling evenly over noodles. Sprinkle with 1/2 cup mozzarella cheese.

8. Second layer

Add another 3–4 noodles. Spread remaining ricotta seafood mixture evenly. Sprinkle with another 1/2 cup mozzarella.

9. Final noodle layer

Add final 3–4 noodles on top.

10. Top with sauce and cheese

Pour remaining white sauce evenly over top layer. Sprinkle with remaining 1 cup mozzarella and 1/4 cup Parmesan.

11. Bake covered

Spray foil with nonstick spray and cover tightly. Bake for 25 minutes.

12. Bake uncovered

Remove foil and bake for 20–25 minutes until golden and bubbly. For extra browning, broil for 2–3 minutes carefully.

13. Rest and serve

Let Seafood Lasagna with Shrimp and Crab rest for at least 10 minutes before slicing.
