Seafood Lasagna with Shrimp & Crab Recipe

Here’s what goes into building this creamy seafood dream:

Lasagna noodles: These provide the base and structure. Use oven-ready noodles to save time.
Shrimp: Peeled and deveined, small to medium shrimp are best for even layering and tender bites.
Crab meat: Lump crab adds a sweet, delicate flavor. Imitation crab can be used if needed.
Ricotta cheese: Creamy and rich, this forms the smooth base of the cheese layer.
Mozzarella cheese: Adds that gooey, melty factor we all love in lasagna.
Parmesan cheese: Sharp and salty, it deepens the flavor of the dish.
Garlic: Minced fresh garlic infuses the sauce with aromatic depth.
Onion: Finely chopped and sautéed for a sweet, savory base.
Butter: Used to sauté and build the creamy white sauce.
Flour: Thickens the sauce into a luscious bechamel.
Milk: The base of the sauce, whole milk works best for richness.
Spinach (optional): A touch of greenery adds contrast and nutrition.
Salt, pepper, Italian seasoning: Essential for seasoning all layers perfectly.

Variations

Add Scallops: Small bay scallops cook fast and blend beautifully with shrimp and crab.
Spicy Kick: Mix in a pinch of red pepper flakes or a diced jalapeño.
Gluten-Free: Use gluten-free lasagna noodles and substitute cornstarch for flour in the sauce.
Low-Fat Option: Swap whole milk with a low-fat version and use part-skim cheeses.

How to Make Seafood Lasagna with Shrimp & Crab

Step 1: Prepare the Sauce

In a large skillet, melt butter and sauté the onion and garlic until translucent. Stir in flour and cook briefly, then whisk in milk to form a creamy bechamel. Simmer until thick, then season with salt, pepper, and Italian herbs.

Step 2: Cook the Seafood

Lightly cook the shrimp in the sauce until just pink, then gently fold in the crab meat. Do not overcook; seafood should stay tender.

Step 3: Assemble the Lasagna

In a baking dish, layer noodles, seafood sauce, dollops of ricotta, a handful of mozzarella, and a sprinkle of Parmesan. Repeat layers until all ingredients are used, finishing with cheese on top.

Step 4: Bake to Perfection

Cover with foil and bake at 375°F for 25 minutes. Remove foil and bake an additional 10-15 minutes until bubbly and golden on top. Let it rest for 10 minutes before serving.

Pro Tips for Making the Recipe

Don’t Overcook the Shrimp: They cook fast and can become rubbery if left too long.
Use Fresh or Thawed Seafood: Avoid using frozen shrimp or crab straight from the freezer. Thaw completely and pat dry.
Layer Evenly: Spread the filling and cheese uniformly for a consistent bite every time.
Let it Rest: Allow the lasagna to sit before cutting to help the layers set beautifully.

How to Serve

This seafood lasagna is rich and satisfying on its own, but here are some pairing ideas:

Garnishes:

Fresh parsley, a squeeze of lemon juice, or a dusting of extra Parmesan.

Side Dishes:

A crisp green salad with vinaigrette or garlic bread makes a perfect companion.

Drinks:

Pair with a chilled glass of white wine like Chardonnay or Sauvignon Blanc.

Make Ahead and Storage

Storing Leftovers

Refrigerate in an airtight container for up to 3 days. The flavors get even better overnight.

Freezing

Wrap tightly in foil and freeze for up to 2 months. Thaw in the refrigerator before baking.

Reheating

Warm in a 350°F oven until hot, or microwave individual portions with a splash of milk to keep it moist.
