Ingredients

12 lasagna noodles, cooked according to package instructions
1 pound large shrimp, peeled, deveined, and chopped
1 pound lump crab meat, picked over for shells
15 ounces ricotta cheese
2 cups shredded mozzarella cheese
½ cup grated Parmesan cheese
3 tablespoons butter
3 tablespoons all-purpose flour
2 cups milk
1 teaspoon garlic, minced
1 teaspoon onion powder
½ teaspoon salt, adjust to taste
¼ teaspoon black pepper
1 teaspoon lemon juice
2 tablespoons chopped fresh parsley, plus extra for garnish
Optional: pinch of nutmeg in béchamel for depth of flavor

Instructions

Step 1: Preheat the oven and prep noodles

Preheat your oven to 375°F (190°C). Cook the lasagna noodles according to package instructions, then drain and set aside on a lightly greased baking sheet to prevent sticking.

Step 2: Make the béchamel sauce

In a medium saucepan, melt butter over medium heat. Add the flour and whisk constantly for 1–2 minutes until it forms a roux. Gradually add milk, whisking continuously to prevent lumps. Cook until thickened, about 5–7 minutes. Stir in garlic, onion powder, salt, pepper, and optional nutmeg. Remove from heat and set aside.

Step 3: Prepare the ricotta mixture

In a large mixing bowl, combine ricotta cheese, chopped parsley, lemon juice, and half of the Parmesan cheese. Mix until smooth. Fold in the chopped shrimp and lump crab meat gently, keeping the chunks intact.

Step 4: Assemble the lasagna

Spread a thin layer of béchamel sauce on the bottom of your baking dish. Place a layer of cooked lasagna noodles on top. Spread one-third of the seafood-ricotta mixture over the noodles, then drizzle a third of the béchamel over the top. Sprinkle a portion of mozzarella cheese. Repeat layers two more times, finishing with béchamel and remaining mozzarella and Parmesan cheese on top.

Step 5: Bake

Cover the lasagna with foil and bake for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the top is golden and bubbly.

Step 6: Garnish and serve

Remove from the oven and let rest for 10 minutes before slicing. Garnish with chopped fresh parsley for color and freshness. Serve warm.

Flavor Profile

This lasagna is creamy, cheesy, and brimming with the sweet, delicate flavors of shrimp and crab. The béchamel sauce adds a rich, velvety texture, while the ricotta provides a subtle tanginess.

The mozzarella and Parmesan form a golden crust that contrasts perfectly with the soft layers beneath. Each bite delivers layers of flavor: a delicate seafood sweetness, a hint of lemon, aromatic parsley, and the satisfying creaminess of cheese and sauce.

Tips for the Perfect Seafood Lasagna

Use fresh seafood whenever possible for the best flavor.
Don’t overmix the ricotta and seafood; you want noticeable chunks.
Be gentle when layering to avoid breaking the noodles.
Let the lasagna rest after baking to set the layers and make slicing easier.
Add a pinch of nutmeg to the béchamel for a warm, aromatic undertone.

Variations

Add a layer of sautéed spinach or mushrooms for extra vegetables.
Substitute half of the shrimp with scallops for a slightly different seafood profile.
Use a mixture of mozzarella and provolone for a smokier cheese flavor.
For a lighter version, use part-skim ricotta and reduce the amount of mozzarella.

Serving Suggestions

Serve with a crisp green salad dressed with lemon vinaigrette.
Pair with garlic bread or focaccia.
A chilled glass of white wine, such as Chardonnay or Sauvignon Blanc, complements the seafood beautifully.

Make-Ahead and Storage

Assemble the lasagna a day in advance and refrigerate until ready to bake.
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat in the oven at 350°F (175°C) until warmed through.

Common Mistakes to Avoid

Overcooking the noodles—they will continue to cook in the oven.
Using canned seafood instead of fresh shrimp and crab for maximum flavor.
Skipping the béchamel—this sauce keeps the lasagna creamy and moist.
Not resting the lasagna after baking, which can cause the layers to slide apart when slicing.

FAQs

Can I use frozen seafood?

Yes, just thaw completely and pat dry to avoid excess moisture.

Can this be made ahead?

Absolutely! Assemble, cover, and refrigerate until ready to bake.

What can I serve with this lasagna?

Salad, garlic bread, roasted vegetables, or a light soup.

Can I make it spicy?

Add a pinch of crushed red pepper to the béchamel or sprinkle over the top before baking.
