Preheat your oven to 375°F (190°C).
In a mixing bowl, combine ricotta cheese, oregano, basil, salt, and pepper.
Spread a thin layer of marinara sauce on the bottom of a baking dish.
Place a layer of lasagna noodles over the sauce.
Spread a layer of the ricotta mixture over the noodles, followed by a layer of shredded chicken, marinara sauce, mozzarella, and Parmesan cheese.
Repeat the layers until all ingredients are used, finishing with a layer of cheese on top.
Cover with aluminum foil and bake for 30 minutes.
Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden brown.
Let it cool for 10 minutes before serving.
