Step 1

Preheat the oven to 190°C (375°F). Cook the lasagna noodles according to package instructions. Drain and set aside.

Step 2

Heat olive oil in a skillet over medium heat. Sauté minced garlic until fragrant, about 1 minute. Add shrimp and cook until pink and opaque, approximately 3-4 minutes. Add crab meat, season with salt, black pepper, and optional red pepper flakes, and cook for 2-3 minutes. Remove from heat and set aside.

Step 3

In a bowl, mix ricotta cheese, 1 cup mozzarella cheese, 1/2 cup Parmesan cheese, heavy cream, and chopped parsley until well combined.

Step 4

Spread a thin layer of Alfredo sauce on the bottom of a 9x13-inch baking dish. Add a layer of lasagna noodles, then spread 1/3 of the cheese mixture over the noodles. Add 1/3 of the seafood mixture on top and drizzle with Alfredo sauce. Repeat this layering process two more times, finishing with noodles and Alfredo sauce on top.

Step 5

Sprinkle the remaining mozzarella and Parmesan cheese over the top layer. Add breadcrumbs for a crunchy texture. Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, until golden and bubbly.

Step 6

Let the lasagna sit for 10 minutes before serving. Garnish with additional parsley if desired.
