  • 8 ounces lump crab meat (real or imitation, drained)
  • 3 garlic cloves, minced
  • Salt and pepper to taste
  • 1/2 teaspoon Old Bay seasoning (optional)
  • 2 tablespoons fresh parsley, chopped

For the Béchamel Sauce:

  • 1/4 cup unsalted butter
  • 1/4 cup all-purpose flour
  • 3 cups whole milk, warmed
  • 1/2 teaspoon salt
  • 1/4 teaspoon ground black pepper

  • 1 tablespoon chopped fresh parsley
  • Salt and pepper to taste

For Assembly:

  • 9-12 lasagna noodles (regular or no-boil)
  • 1 cup shredded mozzarella (for topping)
  • 1/4 cup grated parmesan (for topping)

Optional Garnishes:

  • Chopped parsley
  • A sprinkle of breadcrumbs

Step-by-Step Instructions

Step 1: Cook the Seafood

Begin by preparing the shrimp and crab filling. Heat olive oil and butter in a large skillet over medium heat. Add the minced garlic and sauté until aromatic but not browned, about 30 seconds. Add the chopped shrimp and cook for 2-3 minutes until just pink. Stir in the crab meat and season with salt, pepper, and Old Bay seasoning if using. Cook another minute, then remove from heat and stir in the fresh parsley. Set aside to cool slightly.

Tip: Do not overcook the shrimp, as it will finish cooking in the oven. You want it just barely opaque when you remove it from the skillet.

Step 2: Make the Béchamel Sauce

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1-2 minutes, stirring constantly to form a roux. Gradually pour in the warm milk while whisking to avoid lumps. Bring the mixture to a gentle simmer and cook until thickened, about 5-7 minutes. Add salt, pepper, and nutmeg, then stir in the parmesan cheese until fully melted. Set aside to cool.

Tip: The sauce should be thick enough to coat the back of a spoon, but not overly dense.

Step 3: Prepare the Cheese Layer

In a mixing bowl, combine ricotta, egg, mozzarella, parmesan, chopped parsley, salt, and pepper. Mix until well incorporated. This mixture adds creamy richness and helps bind the layers together.

Step 4: Cook the Noodles

If you’re using regular lasagna noodles, cook them in salted boiling water according to package instructions until al dente. Drain and lay flat on a clean towel to prevent sticking. If you’re using no-boil noodles, ensure your béchamel sauce is slightly thinner to allow them to cook through during baking.

Step 5: Assemble the Lasagna

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

  1. Spread a thin layer of béchamel sauce on the bottom of the dish.
  2. Place a layer of noodles over the sauce.
  3. Spread half of the ricotta cheese mixture over the noodles.
  4. Distribute half of the seafood mixture evenly.
  5. Drizzle with about one-third of the béchamel sauce.
  6. Repeat the layers: noodles, remaining ricotta, remaining seafood, another third of the béchamel.
  7. Add a final layer of noodles, top with remaining béchamel, then sprinkle with mozzarella and parmesan.

Cover loosely with foil (you can use toothpicks to prevent cheese from sticking to the foil).

Step 6: Bake the Lasagna

Bake covered for 25-30 minutes. Remove foil and bake an additional 15-20 minutes, until the top is golden and bubbly. Let the lasagna rest for at least 15 minutes before slicing. This helps it set and makes serving cleaner.

Optional: For a crispy topping, broil on high for 1-2 minutes, watching carefully to prevent burning.

Serving Suggestions

This seafood lasagna pairs beautifully with light, fresh sides:

  • A simple green salad with lemon vinaigrette
  • Garlic bread or warm crusty rolls
  • Roasted asparagus or steamed broccoli
  • White wine such as Chardonnay or Pinot Grigio

To brighten up the plate, garnish with fresh parsley or a lemon wedge.

Storage and Reheating

Refrigerator: Store cooled leftovers in an airtight container for up to 3 days.

Freezer: Wrap individual portions or the whole lasagna tightly with foil and freeze for up to 2 months. Thaw overnight in the fridge before reheating.

Reheating: Bake covered in the oven at 350°F until warmed through (about 20-25 minutes). For smaller portions, use the microwave with a splash of milk or cream to keep the texture creamy.

Recipe Tips and Variations

  • Add vegetables: Sautéed spinach, mushrooms, or zucchini can be layered with the seafood for added nutrition and texture.
  • Switch the cheese: Use fontina or gruyère in place of mozzarella for a different cheesy profile.
  • Use seafood mix: A combination of scallops, lobster meat, or firm white fish can complement or replace shrimp and crab.
  • Make it spicy: Add a pinch of red pepper flakes to the béchamel or seafood mix for heat.
  • Herbs: Fresh basil or thyme can be mixed into the ricotta or sprinkled on top.
