Why This is the Best Seafood Lasagna Recipe

This isn’t just another pasta bake; it’s a culinary masterpiece designed for true flavor enthusiasts. What sets this recipe apart is its commitment to a perfectly balanced, creamy texture that never feels heavy.

We use a classic French béchamel sauce, enriched with garlic, white wine, and Parmesan, which creates a savory foundation that elevates the seafood instead of overpowering it. Unlike recipes that can turn out watery, we provide specific techniques to ensure your seafood is perfectly cooked and your sauce is thick and stable, resulting in flawless, restaurant-quality slices every time.

The Stars of the Show: Key Ingredients

The magic of this dish lies in the quality of its components. Using fresh, high-quality ingredients will guarantee the most delicious outcome.

The Seafood Medley

A combination of shrimp, sea scallops, and lump crab meat provides a wonderful variety of textures and flavors. We recommend using raw, peeled, and deveined shrimp and dry-packed sea scallops to control the cooking process and minimize excess water.

The Creamy White Sauce

The heart of our creamy seafood lasagna is the béchamel sauce. This classic white sauce is made from a simple roux (butter and flour), milk, and seasonings. We enhance ours with a splash of dry white wine, minced garlic, and freshly grated Parmesan and nutmeg to create a deep, savory flavor that ties everything together.

The Cheesy Layers

We use a trio of cheeses for the ultimate in creamy, gooey goodness. Whole milk ricotta cheese forms the base of our cheese filling, mixed with egg and parsley for structure and freshness. Low-moisture mozzarella cheese provides that classic, irresistible cheese pull, while grated Parmesan adds a sharp, salty finish.

How to Make Seafood Lasagna: A Step-by-Step Guide

Making this incredible Seafood Lasagna is a rewarding process. Follow these steps carefully for a perfect result.

Step 1: Prepare the Seafood

First, gently pat your shrimp and scallops completely dry with paper towels. This is a crucial step to prevent a watery lasagna. Season them lightly with salt and pepper. In a large skillet, heat a tablespoon of butter and a tablespoon of olive oil over medium-high heat. Sear the shrimp and scallops in a single layer for about 60-90 seconds per side, just until they are lightly golden but not cooked through. Remove them from the skillet and set aside.

Step 2: Make the Creamy Béchamel Sauce

In the same skillet, melt the remaining butter over medium heat. Add the minced garlic and cook for one minute until fragrant. Whisk in the flour to create a paste (a roux), and cook for two minutes, stirring constantly. Slowly pour in the white wine, whisking to deglaze the pan. Gradually whisk in the milk until the mixture is smooth. Let it simmer for 5-7 minutes, stirring often, until the sauce thickens enough to coat the back of a spoon. Remove from heat and stir in the Parmesan cheese, salt, pepper, and a pinch of nutmeg.

Step 3: Mix the Ricotta Filling

In a medium bowl, combine the whole milk ricotta cheese, a beaten egg, fresh parsley, salt, and pepper. Mix until everything is well incorporated. This mixture will add a wonderful creamy texture and richness to your lasagna layers.

Step 4: Assemble the Lasagna Layers

Preheat your oven to 375°F (190°C). Spread a thin layer of the béchamel sauce on the bottom of a 9×13 inch baking dish. Arrange a layer of oven-ready lasagna noodles on top. Spread half of the ricotta mixture over the noodles. Arrange half of the seared shrimp and scallops and half of the lump crab meat over the ricotta. Top with a layer of shredded mozzarella. Spoon about one-third of the remaining béchamel sauce over the cheese. Repeat the layers one more time: noodles, the remaining ricotta, the rest of the seafood, mozzarella, and another third of the béchamel. Finish with a final layer of noodles, the last of the béchamel sauce, and a generous sprinkling of Parmesan cheese.

Step 5: Bake to Golden Perfection

Cover the baking dish with foil and bake for 30 minutes. Remove the foil and continue to bake for another 15-20 minutes, or until the top is bubbly and golden brown. Let the lasagna rest for at least 15 minutes before slicing and serving. This allows the layers to set, ensuring clean, beautiful slices.

Pro Tips for a Perfect Seafood Lasagna

For a truly exceptional dish, keep these tips in mind:

• Don’t Overcook the Seafood: The seafood will continue to cook in the oven. A quick sear is all you need to develop flavor without making it tough.
• Use Low-Moisture Mozzarella: Fresh mozzarella contains a lot of water and can make your lasagna soupy. Stick to the low-moisture kind for the best results.
• Let It Rest: This is the most important tip! Letting the lasagna sit before cutting is essential. It allows the cheese and sauce to set, so your slices hold their shape. If you love cheesy pasta dishes, you should also check out our Creamy Chicken Penne.

Frequently Asked Questions

What to Serve With Your Lasagna

This creamy seafood lasagna is rich and satisfying, so it pairs best with simple, fresh side dishes. A crisp green salad with a lemon vinaigrette is a perfect choice to cut through the richness.
