Description

An easy, comforting one-pan pasta bake where dry pasta and meatballs cook together in a rich tomato sauce, finished with melted cheese. Perfect for busy weeknights with minimal prep and cleanup.


Ingredients

12 oz short-cut pasta (penne, fusilli, or cavatappi)

8 oz mushrooms, sliced

3 cups marinara sauce

to 3 cups chicken, beef, or vegetable broth

23 cloves garlic, minced

16 oz frozen meatballs, thawed

2 cups shredded mozzarella cheese

½ cup freshly grated Parmesan cheese

Salt and black pepper, to taste

Fresh parsley or basil, chopped (optional, for garnish)


Instructions

  1. Preheat the oven to 425°F (220°C). Lightly grease a large, deep baking dish.
  2. Add the dry pasta, mushrooms, marinara sauce, broth, and garlic to the dish. Stir well to combine.
  3. Arrange the thawed meatballs evenly throughout the pasta mixture, pressing them slightly into the sauce.
  4. Cover the dish tightly with foil or parchment paper and bake for 40–45 minutes, stirring once halfway through. If the mixture looks dry, add up to ½ cup additional broth or water.
  5. Remove the cover and check the pasta for doneness. If needed, cover again and bake for an additional 6–8 minutes until the pasta is tender.
  6. Sprinkle the mozzarella and Parmesan evenly over the top. Return the dish to the oven uncovered and bake for 10–15 minutes, or until the cheese is melted and lightly golden.
  7. Season with salt and pepper to taste. Garnish with fresh herbs if desired. Let rest for a few minutes before serving.

Notes

  • Different pasta shapes absorb liquid differently; adjust broth as needed.
  • Shredding cheese from a block gives the best melting results.
  • This dish can be assembled ahead of time and baked later, or frozen after baking for easy future meals.
  • Letting the casserole rest after baking helps thicken the sauce naturally.
