I saw this on Martha Stewart's website and had to try it. Though it was a bit time consuming to make ( pushing meat sauce into pasta holes ), I was happy with the outcome. I just used my favorite spaghetti meat sauce. You can check out the website for the recipe. This is great for a family get together and a wonderful alternative to lasagna. You can always adjust the ingredients according to your taste.
Butter a 9-inch springform pan. Toss pasta with Parmesan cheese. Tightly pack pasta into pan, standing each piece on end.
Spread 2 cups of meat sauce on top of pasta, pushing it into holes. Bake for 15 minutes. Sprinkle mozzarella on top and place back into the oven until the cheese has melted.
Remove from oven and let stand 15 minutes before unmolding and cutting into wedges.
