Preheat your oven to 375°F (190°C).
Cook the lasagna noodles according to the package instructions until al dente. Drain and set aside.
In a mixing bowl, combine the shredded chicken, ricotta cheese, grated Parmesan cheese, Italian seasoning, garlic powder, salt, and pepper. Mix well to combine.
Spread a thin layer of marinara sauce on the bottom of the 9x13 inch baking dish.
Place a layer of lasagna noodles over the sauce. Spread half of the chicken and ricotta mixture over the noodles. Top with a layer of marinara sauce and sprinkle with mozzarella cheese.
Repeat the layers: noodles, chicken and ricotta mixture, marinara sauce, and mozzarella cheese. Finish with a final layer of noodles and the remaining marinara sauce on top. Sprinkle with the remaining mozzarella cheese.
Cover the baking dish with aluminum foil, making sure it doesn’t touch the cheese.
Bake in the preheated oven for 30 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
Remove from the oven and let the lasagna sit for about 10 minutes before slicing. This will help the layers hold together when serving.
Garnish with fresh basil if desired and serve hot.
