The Building Blocks of a Luxurious Lasagna
This Seafood Lasagna is made with a rich, creamy white sauce and is loaded with delicious shrimp and crab.
1 pound lasagna noodles
1/2 cup unsalted butter
1/2 cup all-purpose flour
4 cups whole milk, warmed
1 cup grated Parmesan cheese
1 teaspoon salt
1/2 teaspoon black pepper
1/4 teaspoon nutmeg
1 pound cooked shrimp, peeled, deveined, and chopped
1 pound lump crab meat
2 cups shredded mozzarella cheese

Crafting Your Seafood Lasagna, Step-by-Step
Cook the Pasta: Cook the lasagna noodles according to package directions. Drain and set aside.
Make the Cream Sauce: In a large saucepan, melt the butter over medium heat. Whisk in the flour and cook for 1 minute to create a roux. Gradually whisk in the warm milk until the sauce is smooth. Cook, stirring constantly, until the sauce thickens, about 5-7 minutes. Remove from the heat and stir in the Parmesan cheese, salt, pepper, and nutmeg.
Assemble the Lasagna: Preheat your oven to 375°F (190°C). Spread a thin layer of the cream sauce in the bottom of a 9×13-inch baking dish. Arrange a layer of cooked lasagna noodles on top. Spread one-third of the remaining sauce over the noodles. Sprinkle with half of the shrimp and half of the crab meat. Repeat the layers: noodles, sauce, and the remaining seafood. Top with a final layer of noodles and the last of the sauce.
Add Cheese and Bake: Sprinkle the shredded mozzarella cheese evenly over the top. Bake for 30-35 minutes, or until the sauce is bubbly and the cheese is golden brown.
Rest and Serve: Let the lasagna rest for 10-15 minutes before slicing and serving. This will help it set and make it easier to cut.
Serving Suggestions and Pro Tips
How to Serve Seafood Lasagna
With a Simple Green Salad: A crisp salad with a light vinaigrette is the perfect contrast to the rich lasagna.
Garlic Bread: Warm, buttery garlic bread is always a welcome addition.
Roasted Asparagus: A side of simple roasted asparagus complements the flavors beautifully.
How to Perfect Seafood Lasagna
Use a Mix of Seafood: Feel free to add other seafood like scallops or lobster for an even more luxurious dish.
Don’t Overcook the Noodles: Cook them just until al dente, as they will continue to cook in the oven.
Use Freshly Grated Cheese: It will melt better and have a superior flavor compared to pre-shredded cheese.
Let It Rest: This is a crucial step to ensure your lasagna holds its shape when sliced.

Best Side Dishes for Seafood Lasagna
Steamed Green Beans: A simple and healthy side that adds a pop of color.
Caesar Salad: A classic pairing that never disappoints.
Artichoke Hearts: Marinated or roasted artichoke hearts are a great complement.
Bruschetta: A light and fresh appetizer to start the meal.
Common Mistakes to Avoid
Making the Sauce Too Thick or Too Thin: Aim for a creamy, gravy-like consistency.
Skipping the Resting Step: Slicing into the lasagna too soon will result in a messy plate.
Using Imitation Crab: For the best flavor and texture, use real lump crab meat.
Over-seasoning: The seafood and cheese are already salty, so be mindful when adding salt.
