Preheat the oven to 375°F (190°C).
Cook the lasagna noodles according to package instructions until al dente. Drain and lay them flat on a clean kitchen towel.
In a mixing bowl, combine the shredded chicken, ricotta cheese, half of the mozzarella cheese, garlic powder, Italian seasoning, salt, and pepper. Mix until well combined.
Spread a thin layer of Alfredo sauce on the bottom of a 9x13 inch baking dish.
Take one lasagna noodle and spread about 1/4 cup of the chicken mixture along its length. Roll the noodle up tightly and place it seam-side down in the baking dish. Repeat with the remaining noodles and filling.
Pour the remaining Alfredo sauce over the rolled lasagna noodles, ensuring they are well coated. Sprinkle the remaining mozzarella and Parmesan cheese on top.
Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.
Let the lasagna rolls cool for 5 minutes before serving. Garnish with chopped parsley.
