Preheat the oven to 375°F (190°C).

In a large pot of boiling salted water, cook the ziti according to package instructions until al dente. Drain and rinse.

In a skillet, heat olive oil over medium heat. Add minced garlic and sauté for about 1 minute until fragrant.

In a large mixing bowl, combine the cooked pasta, marinara sauce, ricotta cheese, Italian seasoning, half of the mozzarella, salt, and pepper. Stir until well-coated.

In a 9x13 inch baking dish, spread half of the ziti mixture. Sprinkle a layer of Parmesan cheese, then pour the remaining ziti on top. Finish with the rest of the mozzarella.

Cover the dish with foil and bake for 20 minutes. Remove the foil and bake for an additional 10 minutes, or until the cheese is bubbly and golden.

Let the ziti rest for a few minutes before serving.
