In a large pot, cook the tortellini according to package instructions. Drain and set aside.
In a large mixing bowl, combine the cooked tortellini, spinach, ricotta cheese, half of the mozzarella cheese, garlic powder, salt, and pepper. Mix well.
Spread the marinara sauce in the bottom of a baking dish. Pour the tortellini mixture over the sauce and spread it evenly.
Sprinkle the remaining mozzarella and Parmesan cheese on top.
Bake in the preheated oven for 25-30 minutes or until the cheese is bubbly and golden.
Let cool for a few minutes before serving. Enjoy!
