Ingredients You’ll Need

For the Seafood Filling:

1 lb shrimp, peeled and chopped
1 cup lump crab meat (or imitation crab)
Optional: 1 cup scallops, cut into pieces
2 tablespoons butter
2 cloves garlic, minced
1 teaspoon Old Bay or seafood seasoning
Salt and black pepper, to taste

For the Creamy Sauce:

4 tablespoons butter
¼ cup flour
3 cups milk or half-and-half
1 cup Parmesan cheese
1 teaspoon Italian seasoning
½ teaspoon onion powder

For the Lasagna Layers:

9–12 lasagna noodles, cooked
2 cups ricotta cheese
2 cups shredded mozzarella
2 tablespoons fresh parsley, chopped

How to Make Seafood Lasagna

Prepare the Seafood:
Melt butter in a skillet. Add garlic, shrimp, crab, and seasoning. Cook 2–3 minutes until the shrimp is pink. Don’t overcook — it will cook more in the oven. Set aside.
Make the Cream Sauce:
In a pot, melt butter and whisk in flour. Slowly pour in milk, whisking constantly until thickened. Add Parmesan, Italian seasoning, onion powder, salt, and pepper. Stir until smooth.
Assemble the Lasagna:
Spread a thin layer of cream sauce in the bottom of a baking dish.
Add noodles → ricotta → seafood mixture → sauce → mozzarella.
Repeat layers until the dish is full. Finish with mozzarella on top.
Bake:
Cover with foil and bake at 180°C (350°F) for 30 minutes.
Remove foil and bake an additional 15 minutes until golden and bubbly.
Rest and Serve:
Let the lasagna rest for 10 minutes before slicing. Garnish with parsley.

Tips & Variations

Add spinach, mushrooms, or sun-dried tomatoes for extra depth.
Use aluminum-free baking pans to avoid metallic flavors with seafood.
Swap ricotta for cream cheese to make the filling richer.
Add lemon zest to the sauce for a fresh, bright flavor.
Substitute crab with lobster for a truly luxurious version.

Final Thoughts

Seafood Lasagna is the perfect combination of creamy, cheesy comfort and elegant seafood flavor. With layers of tender shrimp, sweet crab, and silky sauce, it’s a dish that tastes like something from a high-end coastal restaurant — yet it’s surprisingly easy to make at home.
