Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

Lasagna Noodles
Lasagna noodles form the structure of the dish, holding together the layers of seafood, sauce, and cheese. Cook them until just al dente to prevent a mushy texture after baking.

Shrimp
Shrimp add a tender, slightly sweet flavor and firm texture. Medium shrimp work best, peeled, deveined, and chopped into bite-sized pieces.

Crab Meat
Crab brings a delicate sweetness that makes this lasagna feel luxurious. Use high-quality lump crab meat and gently check for shell fragments.

Butter
Butter forms the base of the white sauce and adds richness. It also helps carry the flavors of the aromatics.

Garlic
Garlic enhances the seafood without overpowering it. Finely minced garlic blends smoothly into the sauce.

All-Purpose Flour
Flour thickens the sauce, creating a creamy consistency that coats each layer evenly.

Milk
Milk provides the body of the white sauce while keeping it smooth and balanced.

Heavy Cream
A small amount of cream adds indulgence and depth to the sauce without making it overly heavy.

Mozzarella Cheese
Mozzarella melts beautifully, creating a stretchy, comforting layer between the noodles.

Parmesan Cheese
Parmesan adds sharpness and depth, balancing the richness of the sauce.

Salt and White Pepper
These seasonings enhance the flavors while keeping the sauce light in color.

Fresh Parsley
Parsley adds freshness and a subtle herbal note that brightens the dish.

Directions

Start by cooking the lasagna noodles according to package instructions until just al dente. Drain and set aside. In a large pan, melt butter over medium heat and sauté the garlic briefly until fragrant. Stir in the flour and cook for a minute to remove any raw taste.

Gradually whisk in the milk and cream, stirring constantly until the sauce thickens and becomes smooth. Season with salt and white pepper. Gently fold in the shrimp and cook just until they begin to turn pink. Remove from heat and stir in the crab meat and parsley.

To assemble, spread a thin layer of sauce in the bottom of a baking dish. Add a layer of noodles, followed by sauce and a sprinkle of mozzarella and Parmesan. Repeat the layers, finishing with sauce and cheese on top.

Bake in a preheated oven at 180°C until bubbly and lightly golden. Allow the lasagna to rest before slicing.

Variations and Customizations

This seafood lasagna is versatile and can be adjusted to suit different tastes. For a more pronounced seafood flavor, you can add scallops cut into small pieces along with the shrimp. I have also tested this recipe with a small amount of lemon zest in the sauce, which adds a subtle brightness that works beautifully with crab.

If you prefer a lighter version, substitute part of the cream with additional milk. For extra richness, ricotta cheese can be layered between the noodles for a creamier texture. You can also add sautéed spinach or mushrooms for extra depth and color.

Cheese lovers may experiment with a blend of mozzarella and Gruyère for a more complex flavor profile. While this dish is elegant as written, these small adjustments allow you to personalize it without losing its refined character.
