  • 1 pound rigatoni pasta
  • 1 pound ground beef
  • 1 small onion, chopped
  • 2 tablespoons olive oil
  • 1 tablespoon minced garlic
  • 28 ounces crushed tomatoes
  • 1 tablespoon sugar
  • 1 teaspoon dried oregano
  • 1 teaspoon salt
  • pinch red pepper flakes
  • ½ cup pasta water
  • 2 cups shredded mozzarella cheese
  • 5 ounces pepperoni slices


  • First get a big pot of water boiling so you can cook your pasta to al dente or minute less than al dente.
  • Preheat oven to 375°F and grease a 9x13 casserole dish with non-stick cooking spray.
  • In a deep sided large skillet, brown ground beef and chopped onions over medium heat until the beef is no longer pink. Drain any grease.
  • Next add the olive oil and minced garlic. Sauté until the garlic is really fragrant, about a minute or so.
  • Then add the crushed tomatoes, sugar, dried oregano, salt and red chili flakes. Let simmer over low heat until the pasta is done cooking.
  • When the pasta is done, reserve ½ cup of the pasta water and then drain the pasta.
  • Remove skillet from heat and add the pasta water, cooked pasta, and most of the pepperoni slices to the sauce. I like to save some slices for the top of the casserole. Stir it all together really well.
  • Spread the mixture into prepared baking dish. Top with any remaining pepperoni slices, and evenly sprinkle the mozzarella cheese over the top.
  • Bake casserole uncovered for 25-30 minutes until bubbly and cheese is fully melted. Let rest about 10 minutes and then serve with grated parmesan cheese and extra red chili flakes.
