In another bowl, mix the 2 cups mozzarella cheese and 2 cups parmesan cheese.
Sauce
In a separate bowl, combine the 18 ounces canned clam chowder, 1 cup heavy whipping cream, 3 tablespoons lemon juice, ½ cup parmesan cheese, 1 teaspoon salt, and ½ teaspoon pepper. Whisk together well.
Ricotta Cheese Mixture
In a medium bowl, add the 16 ounces ricotta cheese, 1 egg, 2 teaspoons minced garlic, ½ cup fresh chopped parsley, and ½ teaspoon salt. Whisk to combine.
To Assemble
To assemble, pour a thin layer of sauce into the bottom of the prepared baking dish. Place a layer of cooked lasagna noodles over the sauce. Next, spread ⅓ of the ricotta mixture, ⅓ of the seafood mixture, then ⅓ of the shredded cheeses.
Repeat the process with sauce, noodles, ricotta, seafood, and cheese twice more, finishing with the cheese mixture on top.
