Ingredients

Scale

Main Ingredients

  • 1 pound frozen meatballs (beef, turkey, or chicken)
  • 2 cups uncooked pasta (such as penne or rotini)
  • 1 24-ounce jar marinara sauce
  • 2 cups water or beef broth

Seasonings

  • 1 teaspoon Italian seasoning
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon red pepper flakes (optional, for a little heat)
  • Salt and pepper, to taste

Toppings and Garnish

  • 2 cups shredded mozzarella cheese
  • Fresh parsley, chopped (for garnish, optional)

Instructions

  1. Preheat and Prepare Baking Dish: Preheat your oven to 425°F (220°C). Grease a 9×13 inch baking dish with cooking spray or butter to prevent sticking.
  2. Combine Ingredients: In the prepared baking dish, add the frozen meatballs, uncooked pasta, marinara sauce, water or beef broth, Italian seasoning, garlic powder, onion powder, red pepper flakes if using, salt, and pepper. Stir everything together until the mixture is well combined and evenly distributed.
  3. Bake Covered: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 30 minutes to allow the pasta to cook and flavors to meld.
  4. Stir and Add Cheese: Carefully remove the foil and give the casserole a gentle stir. Sprinkle the shredded mozzarella cheese evenly over the top of the casserole.
  5. Bake Uncovered: Return the casserole to the oven, uncovered, and bake for an additional 10-15 minutes until the cheese is melted, bubbly, and slightly golden on top.
  6. Cool and Garnish: Remove the casserole from the oven and let it cool for a few minutes. Garnish with chopped fresh parsley if desired, then serve hot for a comforting and easy meal.

Notes

  • You can substitute beef broth with water for a milder flavor or use chicken broth for a different twist.
  • Frozen meatballs should be fully frozen and do not need to be thawed before baking.
  • Feel free to use any short pasta you prefer; rotini and penne hold sauce well.
  • If you like extra cheese, add more mozzarella or sprinkle with parmesan before serving.
  • For a spicier casserole, increase the red pepper flakes or add a dash of hot sauce.
  • Leftovers can be stored in the refrigerator for up to 3 days and reheated in the oven or microwave.
