Ingredients
  

Pasta

  • 8 ounces spaghetti noodles broken in half, cooked, drained, and cooled
  • 2 ½ cups mozzarella cheese shredded, divided
  • ¼ cup grated Parmesan Cheese
  • ¼ cup whole milk
  • 1 large egg beaten
  • 1 teaspoon Italian seasoning
  • ½ teaspoon garlic salt

Sauce

  • 1 pound Italian sausage mild
  • 24 ounce jar marinara sauce
  • 1 teaspoon Italian seasoning
  • 35 slices pepperoni
  • 1/2 tablespoon basil

Instructions
 

  • Before starting the steps of this recipe, break the spaghetti noodles in half and follow the package instructions to boil, drain, and allow them to cool.
  • Preheat oven to 425 degrees F.
  • Spray a 9 x 13 inch baking dish with non-stick cooking spray.
  • In a large bowl, combine the cooled spaghetti noodles, 1/2 cup of mozzarella cheese, parmesan cheese, milk, an egg, Italian seasoning, and garlic salt.
  • Transfer noodle mixture to the prepared baking dish and spread it into an even layer. Place in the oven, bake uncovered for 15 minutes.
  • While pasta is baking, prepare the sauce. Brown Italian sausage in a large skillet over medium heat for about 8 minutes, then drain any excess grease.
  • Pour the marinara sauce over the cooked Italian sausage in the skillet, then mix in the Italian seasoning. Stir well to combine the sauce with the sausage.
  • When the oven timer for the baked pasta goes off, remove pan from the oven and lower the temperature to 350 degrees F.
  • Spread the meat sauce evenly over the cooked noodles in the pan, then add the remaining 2 cups of cheese on top.
  • Layer pepperoni slices on top of the cheese and sprinkle with a dusting of basil.
  • Return to the oven and bake uncovered for 25 to 30 minutes.
