Equipment

  • 1 Large pot (for boiling spaghetti)
  • 1 Colander (for draining pasta)
  • 1 Large mixing bowl
  • 1 9x13-inch baking dish (or oven-safe skillet)

Ingredients

  • 8 oz uncooked spaghetti
  • 1 lb. ground Italian sausage
  • 1 tsp Italian herb blend
  • 1 tsp garlic powder
  • 1 tsp kosher salt (plus extra for pasta water)
  • ½ tsp black pepper
  • 2 cups marinara or spaghetti sauce
  • 2 cups shredded mozzarella cheese
  • 8-10 slices pepperoni slices
  • 2 tbsp chopped fresh parsley (optional, for topping)

Instructions

  • Preheat to 375°F (190°C).
  • In a pot of generously salted water, cook spaghetti until just al dente. Drain and set aside.
  • Ina large skillet over medium heat, brown the sausage until fully cooked, breaking it apart with a spoon. Stir in the Italian seasoning, garlic powder, salt, and pepper. Let the spices toast for a minute.
  • In a large bowl, toss the cooked spaghetti with the sausage mixture and tomato sauce until everything is evenly coated.
  • Grease a 9x9-inch baking dish (or round equivalent) and spread the spaghetti mixture into it. Sprinkle the mozzarella over the top and arrange the pepperoni slices.
  • Bake uncovered for 20–25 minutes, or until the cheese is bubbly and the edges are lightly crisped.
  • Let it rest for a few minutes, then sprinkle with fresh parsley. Slice like a pie and dig in!
