Cook the lasagna noodles according to package instructions until al dente. Drain and lay them flat on a kitchen towel to prevent sticking.
In a mixing bowl, combine the shredded chicken, ricotta cheese, half of the mozzarella, grated Parmesan cheese, garlic powder, Italian seasoning, salt, and pepper. Mix until well combined.
Spread a layer of Alfredo sauce on the bottom of a 9x13 inch baking dish, enough to coat the bottom.
Take one lasagna noodle and place about 1/4 cup of the chicken and cheese mixture along one edge. Carefully roll the noodle up to enclose the filling. Place it seam-side down in the baking dish. Repeat with the remaining noodles and filling.
Once all roll-ups are in the dish, pour the remaining Alfredo sauce over the top and sprinkle with the remaining mozzarella cheese.
Cover the dish with aluminum foil (to prevent sticking, you can spray the foil with cooking spray) and bake for 20 minutes.
Remove the foil and bake for an additional 10-15 minutes or until the cheese is bubbly and golden.
Let the lasagna roll-ups cool for a few minutes before serving. Garnish with fresh parsley.
