Bring a large pot of salted water to a boil. Add the 9 lasagna noodles and cook until al dente, about 8-10 minutes. Stir occasionally to prevent sticking. Drain in a colander and rinse with cold water to stop the cooking process. Lay them flat on a clean kitchen towel to dry.
In a bowl, toss the shredded chicken with olive oil, garlic powder, Italian seasoning, salt, and pepper to evenly coat and flavor the chicken.
In a separate bowl, combine the ricotta cheese, half of the shredded mozzarella, and half of the Parmesan cheese. Stir until smooth and well incorporated.
Spread a thin layer of Alfredo sauce on the bottom of a 9x13-inch baking dish. Lay 3 lasagna noodles in a single layer. Spread half of the ricotta cheese mixture over the noodles, followed by half of the seasoned chicken. Drizzle with a third of the Alfredo sauce. Repeat the layers: noodles, ricotta mixture, chicken, and Alfredo sauce. Finish with a final layer of noodles, the remaining Alfredo sauce, and the rest of the mozzarella and Parmesan cheeses evenly sprinkled on top.
Preheat your oven to 375°F (190°C). Cover the dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes until the cheese is golden and bubbling.
Let the lasagna bake cool for 10 minutes before slicing. Garnish with fresh basil leaves for a pop of color and fresh flavor. Serve hot and enjoy!
