Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine the shredded chicken and buffalo sauce. Mix well until the chicken is fully coated.
In another bowl, mix the ricotta cheese, 1 cup of mozzarella cheese, Parmesan cheese, garlic powder, onion powder, Italian seasoning, salt, and pepper until well combined.
Cook the lasagna noodles according to package instructions until al dente. Drain and set aside.
Spread a thin layer of the buffalo chicken mixture on the bottom of a 9x13 inch baking dish.
Layer 3 lasagna noodles over the chicken mixture, then spread half of the ricotta cheese mixture over the noodles.
Add another layer of the buffalo chicken mixture, followed by 3 more lasagna noodles, the remaining ricotta cheese mixture, and then another layer of buffalo chicken.
Top with the final 3 lasagna noodles and the remaining buffalo chicken mixture. Sprinkle the remaining mozzarella cheese on top.
Cover the dish with aluminum foil and bake for 25 minutes. Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden.
Let the lasagna cool for 10 minutes before slicing. Garnish with fresh parsley if desired.
