Creamy layers of pasta, tender shrimp, sweet crab, and a rich, velvety sauce come together to create a meal that’s perfect for holidays, dinner parties, or whenever you want to serve something truly special. Unlike traditional meat lasagna, this version highlights delicate seafood flavors balanced with herbs, garlic, and cheese for an elegant, flavor-packed result.
Below is a detailed, step-by-step recipe to help you create a spectacular Seafood Lasagna with Shrimp and Crab that tastes like it came straight from a fine dining restaurant.
Seafood Lasagna with Shrimp and Crab
Creamy, Elegant & Flavor-Packed
Ingredients (Serves 6–8)
For the Seafood Filling:
- 450 g (1 lb) raw shrimp, peeled, deveined, and chopped
- 350 g (12 oz) lump crab meat, drained and checked for shells
- 2 tablespoons butter
- 3 cloves garlic, minced
- 1 small shallot, finely diced
- ½ cup dry white wine (optional but recommended)
- 1 tablespoon fresh lemon juice
- 2 tablespoons chopped fresh parsley
- 1 teaspoon dried Italian seasoning
- Salt and freshly ground black pepper to taste
For the Creamy White Sauce (Béchamel-Style):
- 4 tablespoons butter
- 4 tablespoons all-purpose flour
- 3 cups whole milk (warmed)
- 1 cup heavy cream
- ½ cup grated Parmesan cheese
- 1 cup shredded mozzarella cheese
- ¼ teaspoon nutmeg
- Salt and white pepper to taste
For the Ricotta Layer:
- 1 ½ cups ricotta cheese
- 1 egg
- ½ cup grated Parmesan
- 1 tablespoon chopped parsley
- Salt and pepper to taste
Additional:
- 9–12 lasagna noodles (oven-ready or boiled)
- 2 cups shredded mozzarella cheese
- Extra parsley for garnish
Step 1: Prepare the Seafood Filling
Begin by heating butter in a large skillet over medium heat. Add the diced shallot and sauté for about 2–3 minutes until softened. Stir in the minced garlic and cook for another 30 seconds until fragrant.
Add the chopped shrimp and cook for about 2–3 minutes, just until they turn pink. Be careful not to overcook, as shrimp can become rubbery. Pour in the white wine and allow it to simmer for 2–3 minutes to reduce slightly. This step adds depth and enhances the natural sweetness of the seafood.
Gently fold in the lump crab meat, lemon juice, parsley, Italian seasoning, salt, and pepper. Cook for another minute, then remove from heat. Set aside to cool slightly.
Step 2: Make the Creamy White Sauce
In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1–2 minutes to form a roux. It should turn lightly golden but not brown.
Gradually whisk in the warm milk, stirring constantly to prevent lumps. Continue whisking until the sauce thickens, about 5–7 minutes. Add the heavy cream and stir until smooth and creamy.
Mix in Parmesan, mozzarella, nutmeg, salt, and white pepper. Stir until the cheese melts completely and the sauce becomes silky. Remove from heat.
This sauce should be thick enough to coat the back of a spoon but still pourable.
Step 3: Prepare the Ricotta Layer
In a mixing bowl, combine ricotta cheese, egg, Parmesan, parsley, salt, and pepper. Stir until smooth and well blended. This layer adds structure and richness to the lasagna.
Step 4: Assemble the Lasagna
Preheat your oven to 180°C (350°F). Lightly grease a 9×13-inch baking dish.
Layering Process:
- Spread a thin layer of white sauce on the bottom of the dish.
- Add a layer of lasagna noodles.
- Spread one-third of the ricotta mixture over the noodles.
- Spoon one-third of the seafood mixture evenly over the ricotta.
- Pour some white sauce over the seafood.
- Sprinkle mozzarella on top.
Repeat this layering process two more times, finishing with noodles, white sauce, and a generous layer of mozzarella on top.
For an extra golden finish, sprinkle additional Parmesan cheese over the top layer.
Step 5: Bake to Perfection
Cover the lasagna loosely with foil (tent it so the cheese doesn’t stick). Bake for 30 minutes.
Remove the foil and bake for an additional 15–20 minutes, until the top is bubbly and lightly golden brown.
Allow the lasagna to rest for at least 15–20 minutes before slicing. This resting period helps the layers set and makes serving easier.
Flavor Tips & Variations
1. Add Spinach
Sauté fresh spinach and layer it with the seafood for added color and nutrients.
2. Include Scallops
For an even more luxurious version, add chopped scallops to the seafood mixture.
3. Lobster Upgrade
For special occasions, replace half the shrimp with lobster meat for an ultra-elegant twist reminiscent of coastal cuisine in Naples.
4. Herb Boost
Fresh dill or tarragon can add brightness and enhance the seafood flavor.
Serving Suggestions
Serve this seafood lasagna with:
- A crisp green salad with lemon vinaigrette
- Garlic bread or crusty baguette
- Steamed asparagus or roasted broccoli
- A chilled glass of Sauvignon Blanc or Chardonnay
The acidity of white wine complements the creaminess beautifully.
Storage & Reheating
Refrigerator: Store leftovers in an airtight container for up to 3 days.

Why This Recipe Works
This seafood lasagna balances richness and freshness. The béchamel-style sauce provides creaminess without overpowering the delicate shrimp and crab. Lemon juice adds brightness, while nutmeg subtly enhances the white sauce. The ricotta layer gives body and prevents the dish from becoming too heavy.
The combination of textures—tender pasta, creamy sauce, and succulent seafood—creates a harmonious bite every time. It’s indulgent without being overwhelming.
