Preheat your oven to 350°F (175°C).

In a large pot, bring salted water to a boil and add the ziti pasta. Cook according to package instructions until al dente. Drain and set aside.

In a large skillet over medium heat, add the Italian sausage. Break it apart with a spatula and cook until browned, about 6-8 minutes. Incorporate the minced garlic and cook for an additional minute.

In a large mixing bowl, combine the cooked pasta, sausage mixture, marinara sauce, ricotta cheese, Italian seasoning, salt, and pepper. Stir until everything is well coated.

In a greased baking dish, pour half of the pasta mixture, spreading it evenly. Layer half of the shredded mozzarella on top. Repeat with the remaining pasta and top with the remaining mozzarella and Parmesan cheese.

Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. After that, uncover and bake for another 10-15 minutes, or until the cheese is melted and bubbly.

Remove from the oven and let it sit for a few minutes. Garnish with fresh basil before serving.
