Begin by boiling a pot of salted water and adding the ziti pasta. Cook until al dente (about 8-10 minutes). Drain and set aside.

In a large skillet, cook the Italian sausage over medium heat until browned and no longer pink, about 5-7 minutes. Make sure to break it up into crumbles as it cooks. Drain excess fat if needed.

In a mixing bowl, combine the cooked ziti, browned sausage, marinara sauce, ricotta cheese, and half of the mozzarella cheese. Add salt and pepper to taste.

Pour the mixture into a greased baking dish. Spread it evenly, and top with the remaining mozzarella and Parmesan cheese.

Preheat your oven to 350°F (175°C). Bake uncovered for about 25-30 minutes, or until the cheese is melted and bubbly.

Remove from the oven, sprinkle with fresh basil, and allow it to cool for a few minutes before serving.
