Preheat oven to 375°F (190°C).
In a skillet, heat olive oil over medium heat. Add minced garlic and cook until fragrant.
Add shredded chicken, oregano, basil, salt, and pepper. Stir well to combine.
Spread a thin layer of marinara sauce on the bottom of a baking dish.
Place a layer of cooked lasagna noodles over the sauce.
Spread a layer of the chicken mixture over the noodles.
Spread a layer of ricotta cheese over the chicken mixture.
Sprinkle a layer of mozzarella cheese over the ricotta.
Repeat layers until all ingredients are used, ending with a layer of marinara sauce and a generous topping of mozzarella and Parmesan cheese.
Cover with aluminum foil and bake for 30 minutes. Remove foil and bake for an additional 15 minutes, or until cheese is bubbly and golden brown.
Let lasagna rest for 10 minutes before serving.
