Ingredients

  • 16 ounces penne pasta (453.6 grams)
  • 1 teaspoon kosher salt or 1/2 teaspoon table salt
  • 1 pound Italian sausage casings removed (453.6 grams)
  • 2 cloves garlic minced
  • 1 green pepper diced
  • 1 teaspoon kosher salt (or 1/2 teaspoon table salt)
  • 1/4 teaspoon black pepper
  • 24 ounces marinara sauce or pizza sauce (680 grams)
  • 2 1/2 cups shredded mozzarella divided (10 ounces or 282.5 grams)
  • 1 1/2 ounces pepperoni (42.5 grams)
  • 1/4 cup sliced olives (35 grams)
  • 1/4 cup shredded Parmesan (25 grams)

Instructions

  • Preheat the oven to 350 degrees Fahrenheit. Spray a 9 by 13 inch baking dish with cooking spray and set aside.
  • Bring a large pot of water to a roaring boil. Season with salt and add the penne pasta, boiling for less than 2 minutes of the suggested cooking time. For example, if the box suggests boiling for 10 minutes, boil for 8 minutes.

  • Preheat a large skillet over medium heat. Add the Italian sausage, breaking it up as you cook. When it is completely broken up and beginning to brown, add the green pepper and garlic. Season with salt and pepper. Sauté until the peppers have begun to soften, about 5 to 7 minutes. Drain the excess grease.
