In the meantime, cook the rigatoni until it's slightly underdone. Drain and rinse with cool water. Toss with parmesan cheese. Lightly oil a 9-inch spring form pan. Tightly pack the rigatoni in the pan, standing on their ends.
Pour the meat sauce over the pasta. Push the meat down into the holes as best you can.
Slide into the oven for 15 minutes. Remove, top with mozzarella cheese, and bake another 10 to 15 minutes, or until cheese is browned and bubbly.
Let sit 15 minutes before slicing and serving!
Top with fresh basil if desired.
Be thou comforted, little dog, Thou too in Resurrection shall have a little golden tail. ~ Martin Luther
