2. Spread 1 cup of the meat sauce on the bottom of a greased 9×13-inch baking dish.

3. Add half of the cooked ziti over the sauce.

4. Spread the entire cheese mixture evenly over the pasta.

5. Layer on half of the remaining meat sauce.

6. Add the rest of the ziti, then top with the remaining meat sauce.
