In a large pot of salted, boiling water, cook the pasta until slightly underdone (al dente) (I cooked mine for 12 minutes when the box indicated 14). One pound of pasta should be cooked in 6 quarts of water—make sure you're using a big enough pot so the pasta doesn’t stick together. When done, rinse with cold water and drain again. Toss the pasta with 1 tablespoon olive oil to coat, then set aside.
1 lb. rigatoni pasta, 2 tbsps. olive oil
Heat the remaining 1 tablespoon olive oil in a large skillet over medium-high heat. Add the ground beef and cook, stirring occasionally, until browned. Add the garlic, 1 teaspoon salt, and pepper. Cook for 2 minutes more.
1 lb. ground beef, 2 cloves garlic, 1 tsp. table salt, 1/4 tsp. freshly ground pepper
Add the crushed tomatoes and simmer until thickened, about 20 minutes.
1 (28 oz.) can crushed tomatoes
Toss the pasta with Parmesan cheese. Butter a 9-inch springform pan and tightly pack the pasta into the pan, standing each piece on end. Spread the meat sauce on top of the pasta.
1 cup finely grated Parmesan cheese, butter
Use a skewer to push the meat sauce down into the standing rigatoni. It doesn’t have to be perfect, but any extra effort here will pay off with every bite packed with pasta and sauce. If some pasta stays empty, don’t worry—it’ll still taste great.
Bake at 400°F for 15 minutes. Sprinkle mozzarella cheese on top and bake for another 10-15 minutes, until the cheese is golden. Remove from the oven and let stand for 15 minutes. Run a knife around the edge to loosen, then unmold.
8 oz. whole milk mozzarella cheese
Cut into wedges and serve with any remaining meat sauce.
