How to Make Seafood Lasagna Shrimp Crab

Creating this pleasing Seafood Lasagna Shrimp Crab is a rewarding process. Follow these steps for an Easy shrimp crab seafood lasagna that will impress:

1. Step 1: Start by cooking your lasagna sheets. Bring a large pot of water to a rolling boil, adding 1 tablespoon liquid crab boil for that authentic seafood flavor. Cook the lasagna noodles until they are al dente, then drain them carefully and lay them flat on a baking sheet to prevent sticking.
2. Step 2: Prepare your seafood. Toss the peeled and deveined 1 pound shrimp and the 1 pound crabmeat with 2 teaspoons Creole or Cajun seasoning. This seasoning mix is key to the overall flavor profile.
3. Step 3: Wilt the spinach. Heat 2 tablespoons olive oil in a large skillet over medium heat. Add the 10 ounces fresh spinach and 1/2 teaspoon salt, sautéing until just wilted. This quick step locks in the spinach’s freshness for your Seafood Lasagna Shrimp Crab.

Bring to a simmer, whisking constantly, until the sauce thickens nicely. Stir in 1 teaspoon liquid crab boil, 1/2 teaspoon Creole seasoning, and 1/4 teaspoon black pepper. Remove from heat and stir in 1/2 cup grated Parmesan cheese and 2 tablespoons fresh basil.
6. Step 6: Prepare the creamy filling. In a separate bowl, combine the softened 8 ounces garlic & herb cream cheese, 1/4 cup sour cream, 1/4 cup grated Parmesan cheese, and 1 tablespoon fresh basil. Mix until smooth and well-combined.
7. Step 7: Assemble the lasagna. Grease a 12″x16″ baking pan. Spread a thin layer of the prepared sauce on the bottom. Arrange a layer of lasagna noodles, followed by a generous spread of the creamy filling, then the seasoned shrimp and crab mixture, the wilted spinach, 2 cups shredded mozzarella cheese, and a good amount of sauce. Repeat these layers two more times, finishing with a final layer of noodles, sauce, and the remaining 1 cup shredded Fontina or Muenster cheese. This layering ensures an incredibly flavorful and Easy shrimp crab seafood lasagna.
