Step‑by‑Step Instructions for Seafood Lasagna with Shrimp and Crab
Step 1: Prep Ingredients
Begin by draining any excess moisture from the shrimp and crab meat to prevent sogginess in your Seafood Lasagna with Shrimp and Crab. If using traditional lasagna sheets, cook them in boiling salted water for about 7-8 minutes until al dente, then drain and rinse with cold water to stop the cooking process. Set aside, ensuring your seafood is cool and ready for layering.
Step 2: Make Filling
In a large mixing bowl, combine the ricotta cheese, half the mozzarella, minced garlic, and chopped parsley. Stir until everything is well combined and creamy. This will be the rich, flavorful filling for your lasagna. Taste and adjust with a pinch of salt and pepper if needed, creating a filling that ensures every bite of your Seafood Lasagna with Shrimp and Crab is delicious.
Step 3: Layering
Preheat your oven to 375°F (190°C). In a generously greased baking dish, start with a thin layer of Alfredo sauce spread evenly across the bottom. Add a layer of lasagna sheets, followed by a mixture of shrimp and crab, and then dollop on a portion of the cheese filling. Repeat the layers, ensuring you finish with another layer of noodles and a final coating of Alfredo sauce on top.
Step 4: Top & Bake
Pour the remaining Alfredo sauce over the last layer of noodles and sprinkle the remaining mozzarella cheese and a generous amount of breadcrumbs on top for crunch. Cover the dish loosely with aluminum foil and place it in the preheated oven. Bake for 25 minutes covered, then remove the foil and bake for an additional 15-20 minutes until the top is golden brown and the sauce is bubbling.
Step 5: Rest & Serve
Once baked, remove your Seafood Lasagna with Shrimp and Crab from the oven and allow it to cool for 10-15 minutes. This resting period helps the layers set, making for cleaner, more beautiful slices. To serve, cut into squares and garnish with extra parsley for a pop of color, bringing the warm, comforting essence of this dish to your table.
