Ingredients
  

  • 1 pound penne pasta
  • 1 pound Italian sausage casings removed
  • 4 oz pepperoni slices divided
  • 24 oz marinara sauce
  • 2 cups shredded mozzarella cheese
  • 1 cup shredded parmesan cheese
  • 1 medium onion diced
  • 3 cloves garlic minced
  • 1 bell pepper diced
  • 8 oz mushrooms sliced
  • 1 teaspoon Italian seasoning
  • Red pepper flakes to taste

Instructions
 

  • Preheat your oven to 375°F (190°C). Grease a 9x13 inch baking dish.
  • Cook pasta in salted water until al dente (about 2 minutes less than package directions). The pasta will continue cooking in the oven, so slightly underdone is perfect.
  • While pasta cooks, brown sausage in a large skillet over medium heat, breaking it into small pieces (about 8-10 minutes). Remove excess fat if desired.
  • Add onions and garlic to the sausage. Cook until onions are translucent (about 5 minutes). If using optional vegetables, add them now.
  • Stir in marinara sauce and half the pepperoni (chopped). Simmer for 5 minutes.
  • Combine the pasta and sauce mixture in the baking dish. Mix in 1 cup mozzarella and ½ cup parmesan.
  • Top with remaining cheese and arrange remaining pepperoni slices on top.
  • Bake for 25-30 minutes until bubbly and cheese is golden brown.
