Description

This Dump-and-Bake Meatball Casserole is a fuss-free, satisfying dinner. It combines saucy pasta, juicy meatballs, and melted cheese in one dish, perfect for busy nights and comfort food cravings. No boiling, browning, or fancy techniques are needed; simply dump everything into a pan and bake.


Ingredients

Scale
  • 1 (16 oz) package frozen fully-cooked meatballs
  • 1 (16 oz) box uncooked rotini pasta
  • 3 cups marinara sauce
  • 3 cups water
  • 1½ cups shredded mozzarella cheese
  • ¼ cup grated Parmesan cheese
  • Salt and pepper to taste
  • Fresh parsley or basil for garnish (optional)

Instructions

  1. Preheat your oven to 425°F (220°C).
  2. In a 9×13-inch baking dish, spread the uncooked pasta evenly.
  3. Add the frozen meatballs over the pasta.
  4. Pour in the marinara sauce and water, stirring gently to ensure the pasta is coated and submerged.
  5. Season with salt and pepper to taste.
  6. Cover the dish tightly with foil and bake for 35 minutes.
  7. Remove the foil, sprinkle mozzarella and Parmesan cheeses over the top.
  8. Return to the oven and bake uncovered for an additional 10–15 minutes, until the cheese is melted and bubbly.
  9. Let it rest for 5 minutes before garnishing with fresh herbs and serving.

Notes

  • Keep meatballs frozen; do not thaw before baking.
  • Use small, sturdy pasta shapes like rotini or penne for best results.
  • Ensure pasta is well-coated with sauce and water before baking.
  • Add cheese only during the final baking stage for perfect melting.
  • Consider adding garlic powder, Italian herbs, or red pepper flakes for extra flavor.
  • Leftovers can be stored in the refrigerator for up to 3 days or frozen for up to 2 months.
