  • 1 pound spaghetti
  • 24 ounces pasta sauce
  • 10.5 ounces french onion soup undiluted
  • 24 slices pepperoni
  • 2 cups mozzarella cheese shredded
  • 8 slices provolone cheese
  • 7 ounces sliced mushrooms canned
  • 2.25 ounces olives sliced
  • ½ cup bell pepper diced
  • ¼ cup diced red onions


  • Pre heat oven to 375 degrees. Spray 9x13 casserole dish with non-stick cooking spray, set aside.
  • Snap the pasta into thirds. Cook spaghetti in salted boiling water to al dente, drain pasta. Do not rinse.
  • Place pasta in a large mixing bowl. Toss spaghetti with the undiluted French Onion Soup. Place the seasoned pasta mixture in the bottom of the baking dish, spread evenly.
  • Pour spaghetti sauce over the noodles, spread evenly.
  • Top with half the slices of pepperoni. Spread with sliced mushrooms, diced bell peppers and sliced olives.
  • Place six slices of provolone cheese on top of the dish, top with the shredded mozzerella cheese. Place the remaining pepperoni slices on top.
  • Cover with aluminum foil and place in oven for 30 minutes or until hot and bubbly.
  • Allow to rest 10 minutes before serving.


Be sure to cook the noodles to al dente and allow the casserole to rest for 10 minutes prior to serving.  
Topping the casserole with a cup of grated parmesan cheese prior to baking will make it even cheesier!
