Description

A delicious and easy-to-make casserole that combines spaghetti and pizza flavors in a hearty dish perfect for dinner.


Ingredients

Scale
  • 8 ounces spaghetti noodles, broken into 2-inch pieces, cooked al dente, cooled
  • 2 ½ cups (282.5 g) mozzarella cheese, shredded, divided
  • ¼ cup (61 g) whole milk
  • 1 large egg, beaten
  • ½ teaspoon Italian seasoning
  • ½ teaspoon garlic salt
  • ¼ teaspoon kosher salt
  • 1 jar (24 ounces) marinara sauce
  • 1 pound ground beef
  • 1 teaspoon Italian seasoning
  • ½ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • 3 ounces sliced pepperoni, about 35 slices, or enough to cover the top

Instructions

  1. Preheat the oven to 425°F and spray a 9×13-inch baking dish with nonstick cooking spray.
  2. In a large bowl, mix together the cooked, cooled noodles, ½ cup of mozzarella cheese, milk, egg, Italian seasoning, garlic salt, and salt.
  3. Spread the mixture into the prepared baking dish in an even layer. Bake for 15 minutes.
  4. While the pasta is baking, make the sauce. In a medium skillet over medium heat, brown the ground beef until no pink remains (about 8 minutes). Drain grease.
  5. To the ground beef, add marinara sauce, Italian seasoning, salt, and pepper. Stir to combine.
  6. After 15 minutes, remove the pasta from the oven. Reduce the oven temperature to 350°F.
  7. Spread the sauce mixture over the noodle mixture. Top with the remaining cheese and a layer of pepperoni slices.
  8. Return to the oven and bake for 25-30 more minutes, or until the cheese is hot and bubbly. Let rest for a few minutes before serving. Enjoy!

Notes

  • Make sure to cook the spaghetti noodles al dente for the best texture in the casserole.
  • You can use Italian sausage instead of ground beef for a different flavor.
  • This casserole can be prepared ahead of time and stored in the refrigerator until ready to bake.
