Creamy Seafood Lasagna with Shrimp and Crab Tips, FAQ & printable recipe

Tips for success

For a deeper depth of flavor, you can infuse the prepared béchamel sauce before building the lasagna. Gently warm the béchamel in a saucepan with a slice of onion, a bay leaf, and a pinch of ground nutmeg for about ten minutes, then strain it before layering.

This simple step adds a subtle aromatic background that beautifully complements the sweet crab and savory shrimp without overpowering the delicate seafood flavors.

When assembling the lasagna, be mindful of how you distribute the seafood throughout the layers. Reserve a few whole sautéed shrimp to place on top of the finished lasagna after baking for an elegant, professional presentation.

For the interior layers, chop the remaining shrimp into bite-sized pieces so that every single forkful of lasagna contains a perfect mix of shrimp, crab, pasta, and creamy sauce, rather than having large, difficult-to-cut pieces of shellfish.

Variations

• Lobster and Scallop Lasagna: Replace the shrimp and crabmeat with chopped lobster meat and bay scallops for an ultra-luxurious twist on this classic seafood dish.
• Spicy Cajun Seafood Lasagna: Add one tablespoon of Cajun seasoning to the béchamel sauce and use pepper jack cheese alongside the mozzarella for a bold, spicy kick.

Storage and make-ahead

Fridge

Store in an airtight container in the refrigerator for up to 3 days. Cool for no more than 2 hours before refrigerating.

Freezer

Freeze for up to 2 months tightly wrapped in foil and plastic. Thaw in the refrigerator overnight before reheating.

Reheat

Bake covered with foil at 325°F (163°C) for 20-25 minutes until the center reaches 145°F (63°C) and is bubbling.

Store any leftovers in an airtight container in the refrigerator within two hours of cooking. Kept properly, the seafood lasagna will remain fresh and delicious for up to three days. To reheat, place individual slices in an oven-safe dish, cover with foil to retain moisture, and bake at 325°F (163°C) until warmed through. Avoid using the microwave if possible, as it can make the shrimp rubbery.

You can assemble this lasagna up to twenty-four hours in advance. Prepare all the layers, cover the baking dish tightly with plastic wrap, and store it in the refrigerator. When ready to bake, remove the plastic wrap, cover the dish with aluminum foil, and bake as directed. You may need to add ten to fifteen minutes to the baking time to ensure it heats completely through from its chilled state.

Serving ideas

Serve this elegant seafood lasagna alongside a crisp, light green salad tossed with a simple lemon vinaigrette. The bright acidity of the lemon dressing cuts through the richness of the béchamel and seafood beautifully, cleansing the palate between bites.

Crusty garlic bread or a warm, artisanal baguette is also an excellent accompaniment, perfect for scooping up any extra creamy white sauce left on the plate.

For drinks, pair this rich dish with a crisp, dry white wine such as Pinot Grigio, Sauvignon Blanc, or an unoaked Chardonnay. The clean, mineral notes and high acidity of these wines perfectly balance the creamy mozzarella and buttery béchamel.

If you prefer non-alcoholic options, a sparkling water infused with fresh lemon or lime slices offers a similarly refreshing contrast that keeps the entire meal feeling wonderfully balanced.

Creamy Seafood Lasagna with Shrimp and Crab

Prep 25 minCook 45 minRest 15 minTotal 1 h 25 minServes 8

Ingredients

• 2 tbsp butter
• 1 lb raw shrimp, peeled and deveined
• 3 cups béchamel sauce, store-bought or made ahead
• 12 lasagna noodles, cooked
• 1 lb shredded lump crabmeat
• 3 cups shredded mozzarella cheese
• 2 tbsp chopped fresh parsley, for garnish

Instructions

1. Melt the butter in a large skillet over medium heat. Add the raw shrimp and sauté for 3 to 4 minutes until they turn pink and opaque. Remove the shrimp from the heat and set them aside, reserving a few whole shrimp for the final garnish.
2. Gently warm the prepared béchamel sauce in a saucepan over low heat, stirring occasionally to ensure it is smooth and pourable. If the sauce is too thick, whisk in a splash of milk or water to reach the desired consistency.
3. Spread a thin layer of the warmed béchamel sauce at the bottom of a 9x13-inch baking dish. Place 4 cooked lasagna noodles on top. Layer with one-third of the shredded lump crabmeat, sautéed shrimp, and shredded mozzarella cheese. Repeat the layers twice more, ending with a generous layer of mozzarella.
4. Preheat the oven to 375°F (190°C). Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes, ensuring the seafood inside reaches a safe internal temperature of 145°F (63°C) and the edges are bubbling.
5. Turn the oven to broil and cook for 2 to 3 minutes until the top mozzarella is golden brown and bubbly. Remove from the oven and let rest for 15 minutes to set. Garnish with chopped fresh parsley and the reserved whole shrimp before slicing.
