Preheat oven to 375°F (190°C).
In a bowl, mix ricotta cheese, garlic powder, Italian seasoning, salt, and pepper.
Spread a layer of Alfredo sauce at the bottom of a baking dish.
Place a layer of cooked lasagna noodles over the sauce.
Spread half of the ricotta mixture, followed by shredded chicken and mozzarella cheese.
Repeat the layering process, finishing with noodles, Alfredo sauce, and remaining mozzarella and Parmesan cheese.
Cover with foil and bake for 25 minutes.
Remove foil and bake for another 10 minutes until the cheese is golden and bubbly.
Garnish with chopped parsley and serve hot.
