For the Lasagna Layers:

2 cups shredded mozzarella cheese
1 cup grated Parmesan cheese
1/2 cup fresh parsley (chopped)

For the White Sauce (Bechamel Sauce):

4 tbsp butter

1 tsp garlic powder
Salt and pepper (to taste)
1/2 cup grated Parmesan cheese (for mixing into the sauce)

How to Make Easy Seafood Lasagna Step-by-Step?

Step 1: Prepare the Seafood Mixture

In a large skillet, heat the olive oil over medium heat. Add the chopped onion and garlic and sauté until softened and fragrant, about 2-3 minutes. Add the shrimp and cook until pink and opaque, about 4-5 minutes. Stir in the crab meat and spinach (if using), and season with salt and pepper. If you want extra flavor, deglaze the skillet with white wine and allow it to cook off. Remove from heat and set aside.

Step 2: Prepare the Bechamel Sauce

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for about 2 minutes to create a roux. Slowly add the warm milk, whisking constantly to prevent lumps. Continue to cook and whisk until the sauce thickens, about 5-7 minutes. Stir in garlic powder, nutmeg, and salt and pepper to taste. Once thickened, remove from heat and stir in 1/2 cup of Parmesan cheese.

Step 3: Assemble the Lasagna

Preheat your oven to 375°F (190°C). In a 9×13-inch baking dish, spread a small amount of the white sauce at the bottom. Layer lasagna noodles on top, followed by a portion of the seafood mixture, some ricotta cheese, and a drizzle of white sauce. Repeat the layers until all ingredients are used up, finishing with a layer of noodles, sauce, and a generous amount of mozzarella and Parmesan cheese on top.

Step 4: Bake the Lasagna

Cover the lasagna with aluminum foil and bake in the preheated oven for 25-30 minutes. After that, remove the foil and bake for an additional 10-15 minutes or until the top is golden and bubbly.

Step 5: Let It Rest and Serve

Once baked, remove the lasagna from the oven and let it rest for about 10-15 minutes before slicing. Garnish with fresh parsley and serve warm.

Variations of Seafood Lasagna

Seafood lasagna can be easily customized based on your preferences. Here are a few variations to consider:

Lobster and Shrimp Lasagna: For a more luxurious dish, add cooked lobster meat along with the shrimp.
Vegetarian Seafood Lasagna: Use a variety of seafood such as scallops, clams, or mussels, and add extra vegetables like zucchini or bell peppers for a lighter, vegetable-forward dish.
Spicy Seafood Lasagna: Add a pinch of red pepper flakes or some chopped fresh chilies to the seafood mixture for a spicy kick.
Gluten-Free Lasagna: Use gluten-free lasagna noodles and ensure that the white sauce is made with gluten-free flour.

Cooking Notes

If you don’t want to boil lasagna noodles, you can use no-boil noodles, which will absorb moisture from the sauce as they bake.
To make this recipe ahead of time, you can assemble the lasagna and store it in the fridge for up to 24 hours before baking. Alternatively, it can be frozen for up to 3 months. Just be sure to let it thaw overnight in the fridge before baking.
You can make your seafood mixture ahead of time, store it in the fridge, and assemble the lasagna the next day.

Serving Suggestions

Seafood lasagna pairs wonderfully with a crisp green salad, some garlic bread, or roasted vegetables. A fresh salad with a lemon vinaigrette helps cut through the richness of the lasagna, while garlic bread adds a crunchy, buttery contrast. A chilled glass of white wine, like Chardonnay or Sauvignon Blanc, will complement the flavors of the seafood perfectly.

Helpful Tips

Make the white sauce slowly: Adding milk too quickly can result in a lumpy sauce. Be sure to whisk constantly while adding the milk to ensure a smooth and creamy consistency.
Don’t skip resting time: Letting the lasagna rest after baking will help the layers set, making it easier to cut and serve.
Use high-quality seafood: Fresh seafood makes all the difference in this recipe. If using frozen seafood, be sure to thaw and drain it thoroughly before adding it to the mixture.

Tips for the Best Seafood Lasagna

Use a variety of seafood: A mixture of shrimp, crab, and lobster adds different textures and flavors to the dish.
Don’t overcook the seafood: Shrimp and other shellfish cook quickly, so be sure not to overcook them to avoid rubbery textures.
Add extra cheese: A generous amount of mozzarella and Parmesan will give your lasagna a beautifully melty and cheesy top.
Layer carefully: Ensure that each layer has a good balance of seafood, sauce, and cheese for even cooking and great flavor.
