Preheat your oven to 375°F (190°C).
In a large bowl, combine the ricotta cheese, egg, oregano, garlic powder, onion powder, salt, and pepper. Mix until well blended.
Spread a thin layer of marinara sauce on the bottom of a 9x13-inch baking dish.
Place three lasagna noodles over the sauce, then spread half of the ricotta mixture over the noodles.
Layer half of the shredded chicken over the ricotta, followed by a third of the mozzarella cheese and a third of the marinara sauce.
Repeat the layers: three more noodles, the remaining ricotta mixture, the remaining chicken, another third of the mozzarella, and another third of the marinara sauce.
Top with the last three noodles, the remaining marinara sauce, the remaining mozzarella, and the Parmesan cheese.
Cover the baking 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 basil leaves if desired.
