Preheat the oven to 375°F and lightly grease a 9x13 baking dish. Bring a large pot of salted water to a boil and cook the ziti according to package directions until al dente. Drain and return the pasta to the pot.

Pour the marinara sauce into the pot with the drained pasta. Add the Italian seasoning along with salt and pepper to taste, then stir until the pasta is evenly coated.

Spread half of the pasta mixture into the prepared baking dish. Dollop half of the ricotta over the top and sprinkle with half of the mozzarella and half of the Parmesan.

Add the remaining pasta mixture on top. Finish with the rest of the ricotta, mozzarella, and Parmesan scattered evenly across the surface.

Bake uncovered for 20 to 25 minutes until the cheese is melted and the edges are bubbling. Let the dish rest for 5 minutes before serving.
