Why I Love This Recipe

Traditional lasagna is always a hit, but swapping in seafood creates a lighter yet luxurious flavor profile. The sweetness of crab and the delicate bite of shrimp pair beautifully with creamy béchamel sauce and mozzarella.

It’s elegant without being complicated — and it always earns compliments.

Step-by-Step Instructions

1. Cook the Seafood
   In a skillet, melt butter over medium heat. Add garlic and sauté for 30 seconds. Stir in shrimp, season with salt, pepper, and Italian seasoning. Cook until shrimp turns pink (about 3–4 minutes). Gently fold in crab meat and remove from heat.
2. Prepare the Cream Sauce
   In a saucepan, melt butter over medium heat. Whisk in flour and cook for 1–2 minutes. Gradually whisk in warm milk and cream. Cook until thickened, stirring constantly. Add Parmesan, nutmeg, salt, and pepper. Stir until smooth.
3. Preheat Oven
   Preheat oven to 375°F (190°C).
4. Layer the Lasagna
   In a greased 9×13-inch baking dish, spread a thin layer of cream sauce. Add lasagna noodles, seafood mixture, ricotta dollops, mozzarella, and more sauce. Repeat layers, finishing with mozzarella and sauce on top.
5. Bake
   Cover with foil and bake for 25 minutes. Remove foil and bake an additional 15–20 minutes until bubbly and golden.
6. Rest Before Serving
   Let lasagna rest for 10–15 minutes before slicing.
