Before we dive into the preparation, let’s ensure you have everything you need to create this delicious masterpiece. Here’s what you’ll need:

• 12 lasagna noodles
• 2 tablespoons olive oil
• 1 pound shrimp, peeled and deveined
• 1 pound crab meat
• 4 tablespoons unsalted butter
• 1/4 cup all-purpose flour
• 3 cups whole milk
• 1 cup heavy cream
• 1 cup grated Parmesan cheese
• 2 cups shredded mozzarella cheese
• 3 cloves garlic, minced
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/4 teaspoon cayenne pepper (optional for a hint of spice)
• 2 tablespoons fresh parsley, chopped
• 1 teaspoon lemon zest

Feel free to substitute the shrimp with scallops if you prefer, and for a lighter version, you can use half-and-half instead of heavy cream.
