Fill a large pot with lightly salted water and bring to a rolling boil over high heat. Once the water is boiling, stir in the ziti, and return to a boil. Cook the pasta uncovered, stirring occasionally, until the pasta has cooked through, but is still firm to the bite, about 8 minutes. Drain well in a colander set in the sink.

While pasta is cooking, heat a large skillet over medium heat. Add the sausage, and cook and stir until brown, about 10 minutes. Drain sausage and set aside.

In the prepared baking dish, cover the bottom with 1/3 jar of spaghetti sauce. Layer 1/2 of the pasta mixture, 1/3 jar of spaghetti sauce, and 1/2 of the shredded cheese. Then layer the remaining 1/2 of the pasta, 1/3 of the sauce, and 1/2 of the cheese. Sprinkle with basil. Cover the dish tightly with aluminum foil.
