Ingredients
  

Ingredients
  • 1 pound frozen, fully cooked meatballs
  • 1 (24-ounce) jar of your favorite pasta sauce
  • 1 cup water
  • 2 cups uncooked pasta (penne, rigatoni, or ziti work best)
  • 1 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese
  • Fresh basil or parsley for garnish (optional)

Equipment

  • 9x13 inch baking dish
  • Aluminum foil

Method
 

Instructions
  1. Preheat and Prep: First things first, get your oven preheating to 375°F (190°C). Grab a 9x13 inch baking dish—this size is perfect to ensure everything cooks evenly without overflowing.
  2. Combine the Core Ingredients: This is the "dump" part! Pour the entire jar of pasta sauce and the cup of water into the baking dish. Add the frozen meatballs and the uncooked pasta directly into the sauce.
  3. Stir It All Together: Give everything a good stir. The most important part of this step is to make sure the pasta is as submerged in the liquid as possible. This is what allows it to cook through perfectly in the oven.
  4. First Bake (Covered): Cover the baking dish tightly with aluminum foil. This traps the steam and essentially boils the pasta right in the sauce. Place it in the preheated oven and bake for 25 minutes.
  5. Add the Cheese and Finish Baking: Carefully remove the dish from the oven and take off the foil. Give the casserole a quick stir. The pasta should be mostly cooked at this point. Sprinkle the mozzarella and Parmesan cheese evenly over the top. Return the dish to the oven, uncovered, and bake for another 5-10 minutes. You're looking for the cheese to be completely melted, bubbly, and just starting to brown.
  6. Rest and Garnish: Let the casserole cool for a few minutes before serving. This allows the sauce to thicken up slightly. Garnish with some freshly chopped basil or parsley for a touch of color and freshness. Enjoy your incredibly easy one-pan meal!

Notes

For best results, use a 9x13 inch baking dish to prevent crowding the pasta. Use a quality pasta sauce and shred your own mozzarella for a better melt. Ensure all pasta is submerged in the sauce mixture before baking to cook evenly. The recipe is adaptable; feel free to swap meatballs (turkey, plant-based), pasta shapes, sauces, cheeses, or add vegetables like spinach or bell peppers.
