Chef’s Pro Tips for Perfect Results

Want to nail this dish on your very first try? Here are some insider secrets…

• Use a mix of seafood—shrimp, scallops, crab meat, or lobster—for the best flavor and texture variety.
• Don’t overcook the seafood before assembling; a quick sauté until just opaque keeps it tender.
• Make sure your béchamel (white sauce) is silky smooth — whisk constantly and add the milk gradually.
• Let the assembled lasagna rest for 15-20 minutes after baking to set up for clean slices.

Ingredients

1. 9-12 lasagna noodles, cooked according to package instructions
2. 1 pound mixed seafood (shrimp peeled and deveined, scallops, crab meat)
3. 4 tablespoons unsalted butter
4. 4 tablespoons all-purpose flour
5. 4 cups whole milk, warmed
6. 1 cup grated Parmesan cheese
7. 2 cups shredded mozzarella cheese
8. 1 small onion, finely chopped
9. 3 cloves garlic, minced
10. 2 tablespoons olive oil
11. Salt and freshly ground black pepper, to taste
12. 2 tablespoons fresh parsley, chopped
13. Optional: pinch of nutmeg for the white sauce

Instructions

1. Preheat your oven to 375°F (190°C).
2. In a large skillet, heat olive oil over medium heat. Add chopped onion and sauté until translucent, about 4-5 minutes. Add garlic and cook until fragrant, about 1 minute.
3. Add the seafood to the skillet and cook just until opaque, about 3-4 minutes. Remove from heat and set aside.
4. In a saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes to form a roux. Gradually add warmed milk, whisking constantly to prevent lumps. Cook until the sauce thickens and coats the back of a spoon, about 7-8 minutes.
5. Stir in Parmesan cheese, salt, pepper, and a pinch of nutmeg if using. Remove from heat.
6. Spread a thin layer of white sauce on the bottom of a baking dish. Layer 3-4 lasagna noodles over the sauce.
7. Add a portion of the seafood mixture, then spoon more white sauce over it. Sprinkle with mozzarella cheese. Repeat the layers until all ingredients are used, finishing with a generous layer of mozzarella on top.
8. Cover with foil and bake for 25 minutes. Remove foil and bake an additional 15 minutes or until bubbly and golden on top.
9. Let rest for 15-20 minutes before slicing and serving. Garnish with fresh parsley.

Texture & Flavor Secrets

The creamy white sauce wraps around tender layers of pasta and juicy seafood, creating a rich, velvety texture that’s light enough to let the fresh flavors shine. The mozzarella adds gooey meltiness while Parmesan brings a sharp, savory punch. Every bite offers a luscious blend of creaminess, delicate seafood sweetness, and cheesy comfort.
