Preheat your oven to 375°F (190°C).

Cook the ziti pasta in a large pot of boiling salted water according to the package instructions until al dente. Drain and set aside.

In a large skillet, heat the olive oil over medium heat. Add the ground beef, seasoning it with salt, pepper, and Italian seasoning. Cook until browned, breaking it apart with a spatula.

Stir in the marinara sauce and let it simmer for about 5 minutes, allowing the flavors to meld.

In a mixing bowl, combine the cooked ziti, ricotta cheese, and half of the mozzarella with the beef mixture. Mix well to ensure the noodles are well-coated.

Transfer the mixture to a baking dish, spreading it out evenly. Top with the remaining mozzarella and the grated Parmesan cheese.

Bake for 25-30 minutes or until the cheese is bubbly and golden brown.

Allow it to cool for a few minutes before serving, letting the layers settle for easy serving.
