How to Make Seafood Lasagna with Shrimp & Crab
-
Prepare Seafood: In a large pan, heat olive oil over medium heat. Add minced garlic, sautéing until fragrant, then toss in the shrimp and crab. Cook until the shrimp turns opaque and the crab is heated through, about 3-5 minutes.
-
Mix Cheeses: In a mixing bowl, combine ricotta cheese, half of the shredded mozzarella, heavy cream, finely chopped parsley, and a pinch of salt, black pepper, and red pepper flakes. Stir well until everything is blended and creamy.
-
Layer Lasagna: Grease a baking dish and spread a layer of Alfredo sauce on the bottom. Layer lasagna noodles, followed by the seafood mixture, then the cheese mixture. Repeat the layering process, ending with noodles topped with the remaining Alfredo sauce, mozzarella, and optional breadcrumbs.
-
Bake: Cover the dish with foil and bake in a preheated oven at 375°F (190°C) for 30-40 minutes. Finally, remove the foil and bake for another 10-15 minutes until the top is golden brown and bubbly.
-
Cooling: Once baked, allow the lasagna to rest for about 10-15 minutes before slicing. This helps the layers set for easy serving.
Optional: Garnish with additional fresh parsley before serving for an inviting touch.
