Equipment

  • 1 9x13-inch baking dish
  • 1 mixing bowl
  • 1 measuring cups
  • 1 measuring spoons
  • 1 aluminum foil optional
  • 1 oven mitts

Ingredients
  

  • 2 cups frozen meatballs About 1 lb.
  • 1 cup uncooked penne pasta
  • 2 cups marinara sauce
  • 2 cups shredded mozzarella cheese
  • 1 teaspoon Italian seasoning
  • 1 teaspoon garlic powder
  • ½ teaspoon salt
  • ¼ teaspoon black pepper
  • 2 cups water
  • Fresh parsley to taste for garnish Optional.

Instructions
 

  • Preheat the oven to 375°F (190°C).
  • In a large mixing bowl, combine the uncooked penne pasta, Italian seasoning, garlic powder, salt, and black pepper. Mix well.
  • Spread the uncooked pasta mixture evenly in the bottom of a 9x13-inch baking dish.
  • Place the frozen meatballs on top of the pasta.
  • Pour the marinara sauce over the meatballs and pasta, making sure it covers everything evenly.
  • Add 2 cups of water to the dish, gently stirring to combine without disturbing the meatballs too much.
  • Sprinkle the shredded mozzarella cheese on top of the casserole.
  • Cover the baking dish with aluminum foil (if desired, to prevent over-browning).
  • Bake in the preheated oven for 30 minutes.
  • Remove the foil and bake for an additional 15 minutes, or until the cheese is melted and bubbly, and the pasta is cooked through.
  • Remove from the oven and let it cool for a few minutes before serving.
  • Garnish with fresh parsley if desired, and serve warm.

Notes

You can substitute the frozen meatballs with homemade meatballs, if preferred.
For a healthier option, use whole grain pasta and low-fat cheese.
This dish pairs well with a simple green salad or garlic bread.
