How to Make Delicious Seafood Lasagna Shrimp Crab

Step 1: Preheat your oven to 375°F (190°C). Get your baking pan ready by greasing it lightly. This initial step ensures everything cooks evenly for a perfect seafood lasagna using shrimp and crab.
Step 2: Cook the lasagna sheets in a pot of boiling water, adding about 2 tablespoons of liquid crab boil for that authentic flavor. Cook them until they’re al dente, then drain and carefully set them aside.
Step 3: While the pasta cooks, toss your prepared shrimp and crabmeat with 2 tablespoons of Creole or Cajun seasoning. This seasoning brings a wonderful warmth and depth to the seafood.
Step 4: In a separate skillet, sauté the fresh spinach in 2 tablespoons of olive oil with a pinch of salt. Cook just until it wilts down, then remove it from the heat and set aside.
Step 5: Now, let’s make that creamy sauce. Melt 4 tablespoons of butter in a saucepan over medium heat. Add 4 cloves of minced garlic and cook until fragrant, about 1 minute. Stir in 1/4 cup of flour and cook for another minute to create a roux. Slowly whisk in 3 cups of half & half and 1 cup of chicken stock. Continue whisking until the sauce thickens beautifully. Season with Creole seasoning, black pepper, and a bit more liquid crab boil. Finally, stir in 1/2 cup of grated Parmesan cheese and 1/4 cup of chopped fresh basil until the cheese is melted and the sauce is smooth. This is a crucial part of how to cook shrimp crab lasagna.
Step 6: In a separate bowl, mix 4 oz of garlic & herb cream cheese, 1/2 cup of sour cream, a little more Parmesan, and some fresh basil until well combined. This creamy layer adds an extra dimension of flavor.
Step 7: Start assembling your lasagna. Spread a thin layer of the Alfredo-style sauce on the bottom of your prepared pan. Layer with lasagna sheets, then spread half of the cream cheese mixture, followed by a layer of the seasoned shrimp and crab, and the sautéed spinach. Sprinkle generously with shredded mozzarella and Fontina cheeses. Repeat these layers twice more, ending with a final layer of sauce and a generous topping of the remaining cheeses. This layering process is key to how to cook shrimp crab lasagna.
Step 8: Bake the assembled lasagna uncovered for 35–45 minutes, or until it’s bubbly and the cheese is melted and golden.
Step 9: For an extra beautiful finish, broil the lasagna for 3–5 minutes until the top is a lovely golden-brown. Keep a close eye on it to prevent burning.
Step 10: Let your masterpiece rest for at least 15 minutes before slicing and serving. This allows the flavors to meld and the lasagna to set, making it easier to cut neat portions.
