Every ingredient in our lasagna contributes to its rich and harmonious flavors. 

Ricotta cheese brings creamy indulgence to each layer, while the shrimp and crab combination adds delightful and varied textures. 

Mozzarella cheese tops the dish with a golden, gooey perfection, making it irresistibly delicious.

You’ll need:

  • 9 lasagna noodles
  • 4 tablespoons of butter
  • 3-4 cloves of garlic, minced
  • ¼ cup of all-purpose flour
  • 1 teaspoon of salt, divided in half
  • 1 teaspoon of pepper, divided in half
  • ¼ cup of sauvignon blanc or pinot grigio (you can substitute clam juice, water, or broth)
  • 3 cups of whole milk
  • 15 ounces of ricotta cheese
  • 1 large egg
  • 1 teaspoon of dried basil
  • 3 tablespoons of lemon juice
  • ½ cup of grated parmesan cheese
  • 1 pound of cooked shrimp, tails removed and cut into large chunks
  • ½ pound of cooked crab (optional)
  • 4 cups of shredded mozzarella cheese, divided into 1 cup, 1 cup, and 2 cups
  • Fresh parsley, chopped for garnish

PRO TIP:

We recommend grating the cheese from the block. Pre-shredded cheese tends to be coated with a preservative that prevents it from melting well.

Substitutions and Additions

CRAB MEAT: The crab meat adds a strong seafood flavor to the dish; you can substitute more shrimp for the crab for a lighter dish.

SHRIMP: We used large prawns, but you can use any size you’d like. The larger prawns add a nice textural change to the dish.

SEAFOOD: Customize your seafood lasagna by using your favorite seafood. Scallops, lobster, or even a seafood medley can be delightful substitutions.

BASIL: Thyme or Italian seasoning can be substituted for dried basil. 

CHEESE: Cheddar, jack, or fontina cheese can be substituted for mozzarella but will change the flavor profile of the dish.

RICOTTA CHEESE: If you prefer a lighter option, consider substituting cottage cheese for ricotta. It will still provide creaminess with a slightly tangy twist.

How To Make This Seafood Lasagna Recipe

STEP ONE: Preheat the oven to 350°F.

STEP TWO: Cook lasagna noodles in a pot of salted, boiling water according to package instructions until al dente. Drain and rinse in cold water.

STEP THREE: In a large saucepan, melt the butter over medium heat. Add the minced garlic and saute for 1-2 minutes until the garlic is toasted.

STEP SIX: Continue heating, cooking over medium-high, and whisking constantly until the mixture comes to a simmer. 

Reduce heat to medium and simmer one minute longer until the sauce has thickened slightly.

STEP SEVEN: In a medium mixing bowl, stir together ricotta cheese, egg, ½ teaspoon salt, ½ teaspoon pepper, basil, lemon juice, and parmesan cheese. Mix until combined.

OUR RECIPE DEVELOPER SAYS

How To Serve

Serve your creamy lasagna with a side of garlic bread and a crisp Caesar salad for a complete Italian-inspired feast.

A side of roasted vegetables would add a pop of color to the plate and balance out the richness of the lasagna.

MAKE AHEAD: Assemble the lasagna up to a day in advance, cover, and refrigerate until ready to bake.
