How to make Decadent Seafood Lasagna with Shrimp & Crab You’ll Love
Step 1: Prepare the Sauce
In a large skillet, melt 2 tablespoons of butter and add 2 tablespoons of olive oil over medium heat. Stir in the minced garlic and sauté until fragrant, about 1 minute. Pour in the heavy cream and let it simmer, stirring occasionally, until it starts to thicken, approximately 5 minutes. Mix in the grated Parmesan cheese until melted and smooth. Season with salt and pepper to taste. Remove from heat.
Step 2: Mix the Filling
In a separate bowl, combine the ricotta cheese, shredded mozzarella cheese, dried oregano, dried basil, crab meat, and cooked shrimp. Stir well until all ingredients are evenly combined and set aside.
Step 3: Assemble the Lasagna
Preheat your oven to 375°F (190°C). In a baking dish, spread a thin layer of the white sauce on the bottom. Place two lasagna noodles over the sauce, followed by a generous portion of the seafood filling and another layer of sauce. Repeat this process, layering noodles, filling, and sauce, until all ingredients are used, finishing with noodles topped with sauce and a sprinkle of extra mozzarella.
Step 4: Bake
Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 15-20 minutes or until the top is golden and bubbly. Allow to cool for 10 minutes before slicing.
Pro Tips and Variations
- Make-ahead: Prepare the lasagna a day in advance and refrigerate it overnight before baking. This allows the flavors to meld more beautifully.
- Vegetarian option: Substitute the seafood with sautéed vegetables like spinach, mushrooms, and zucchini for a delightful veggie dish.
- Gluten-free: Use gluten-free lasagna noodles to cater to dietary restrictions.
- Storage: Keep leftovers in an airtight container in the fridge for up to 3 days. Reheat in the oven or microwave until heated through.
How to Serve
Garnish your seafood lasagna with fresh chopped parsley for a pop of color. Serve alongside a crisp Caesar salad and garlic bread for a balanced meal. A chilled glass of white wine, such as Pinot Grigio, pairs beautifully with the flavors of the seafood. For an elegant presentation, consider plating each slice neatly on a warm plate, drizzling with a little extra sauce and a sprinkle of cheese.
Common Questions

- What can I use instead of crab? You can use more shrimp or a mixture of other seafood like scallops or lobster for a different flavor profile.
- How do I prevent the dish from becoming watery? Be sure to drain any excess liquid from the crab and shrimp to keep the filling from being too runny.
