Why This Recipe Works

Everything bakes together in one dish, keeping prep and cleanup simple
Uncooked pasta absorbs flavor directly from the sauce as it cooks
Frozen precooked meatballs make this recipe reliable and time-saving
A two-stage bake ensures tender pasta and evenly melted cheese
The structure works well for both make-ahead and same-day cooking

Ingredients

16 oz uncooked rotini or penne pasta
3 cups water
1 24 oz jar marinara sauce
1 14 oz package frozen precooked meatballs (thawed overnight)
½ tsp crushed red pepper optional
2 cups shredded mozzarella cheese
Fresh parsley optional, for garnish
Shredded Parmesan cheese optional, for serving

Step-by-Step Instructions

Preheat the oven to 425°F (220°C). This high heat helps the pasta cook evenly and allows the casserole to bake thoroughly from the start.
In a 9×13-inch baking dish, add the uncooked pasta, water, marinara sauce, and thawed meatballs. Sprinkle in the crushed red pepper if using. Stir thoroughly so the pasta is evenly distributed and submerged in the liquid.
Cover the dish tightly with foil, sealing the edges to trap steam. Place the casserole in the oven and bake for 30 minutes, allowing the pasta to soften and absorb the sauce.
Carefully remove the foil and stir the casserole well, making sure nothing sticks to the bottom. Check the pasta for doneness. If it is not yet al dente, return the dish to the oven and bake for an additional 5 to 10 minutes.
Once the pasta is tender, stir 1 cup of the shredded mozzarella cheese directly into the casserole, ensuring it melts evenly throughout. Sprinkle the remaining cup of mozzarella over the top.
Return the dish to the oven uncovered and bake for another 10 to 15 minutes, until the cheese on top is fully melted and bubbly with light golden spots.
Remove the casserole from the oven and let it rest for about 5 minutes. Garnish with fresh parsley and shredded Parmesan cheese if desired before serving.

Expert Tips for Best Results

Make sure the pasta is fully covered by liquid before baking. This ensures even cooking and prevents dry edges or undercooked pieces.

Stirring halfway through baking is essential. It redistributes heat and moisture, helping the pasta cook uniformly and preventing sticking.

Letting the casserole rest after baking allows the cheese and sauce to settle. This makes serving cleaner and improves the overall texture.

Use a tightly sealed foil covering during the first bake. Trapped steam is what allows the uncooked pasta to soften properly.

Storage and Reheating

Allow leftovers to cool completely before transferring them to an airtight container. Stored in the refrigerator, the casserole keeps well for several days without losing its texture.

To reheat, cover and warm in the oven at a moderate temperature or microwave individual portions. Add a small splash of water or sauce if needed to loosen the pasta before reheating.
