Let's Cook
-
Step 1.
Preheat the oven to 350°F. Lightly grease a 9x13-inch baking dish with vegetable oil.
-
Step 2.
Bring a large pot of salted water to a boil. Cook 9 lasagna noodles according to package directions until al dente, then drain and set aside.
-
Step 3.
While the noodles cook, in a large mixing bowl, combine 1 pound chopped cooked lobster meat, 1 pound chopped cooked crabmeat, and 1 pound diced raw shrimp. Add ½ cup chopped green onions and 4 teaspoons Old Bay seasoning. Fold gently until well combined, then set aside.
-
Step 4.
In a large saucepan, melt 5 tablespoons salted butter over medium heat. Sprinkle in 3 tablespoons all-purpose flour and whisk continuously until smooth and bubbly, about 1 minute. Gradually pour in 3 cups heavy cream, whisking constantly to prevent lumps. Cook, whisking often, until the sauce thickens enough to coat the back of a spoon, about 3-5 minutes.
-
Step 5.
Add 5 minced garlic cloves, 2 teaspoons seasoning salt, and 1 teaspoon coarse black pepper to the sauce. Whisk well, then stir in 1 cup shredded Parmesan cheese. Continue whisking until the cheese is melted and the sauce is smooth. Cook for 2 more minutes, then remove the saucepan from the heat.
-
Step 6.
In a separate bowl, combine 2 cups cubed creamy Havarti and 1½ cups shredded mozzarella cheese. Set aside.
-
Step 7.
Assemble the lasagna: Spread a thin layer of the cheese sauce (about ¼ cup) on the bottom of the prepared baking dish. Place 3 lasagna noodles over the sauce. Spread half of the seafood mixture evenly over the noodles. Spoon one-third of the remaining cheese sauce over the seafood, then sprinkle one-third of the Havarti-mozzarella mixture on top. Repeat the layers: 3 noodles, remaining seafood, another third of the cheese sauce, and another third of the cheese mixture. Finish with the last 3 noodles, the remaining cheese sauce, and the remaining Havarti-mozzarella mixture.
-
Step 8.
Sprinkle dried parsley flakes over the top. Cover the baking dish tightly with aluminum foil. Bake for 1 hour and 25 minutes, until the lasagna is hot and bubbly. Remove from the oven and let rest for about 15 minutes before serving.
