Ingredients

Ingredient	Quantity
Dry rotini pasta	12 oz (about 3 cups, uncooked)
Marinara or pasta sauce	24 oz jar
Water	3 cups
Frozen fully cooked meatballs	1 lb
Shredded mozzarella cheese	2 cups

---

Instructions

1. Preheat and prepare the dish
Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch glass baking dish to prevent sticking.

2. Add the dry pasta
Pour the dry rotini into the baking dish and spread it into an even layer. Do not cook the pasta first.

3. Mix the sauce and water
In a medium bowl or large measuring cup, stir together the marinara sauce and the water until well blended. This extra liquid allows the dry pasta to cook right in the oven.

4. Add meatballs and liquid
Scatter the frozen meatballs evenly over the dry pasta. Pour the sauce-water mixture over everything, making sure the liquid seeps down into the pasta. Gently press any dry pasta pieces into the liquid if needed.

5. Bake covered
Cover the baking dish tightly with aluminum foil. Bake for 30 minutes.

6. Add cheese and finish baking
Remove the foil. Sprinkle the shredded mozzarella evenly over the top. Return the dish to the oven (uncovered) and bake for another 10–15 minutes, until the pasta is tender, the meatballs are hot, and the cheese is melted and bubbly.

7. Rest and serve
Let the casserole rest for 5 minutes before serving. Scoop into bowls with a big spoon and enjoy.

Serving Suggestions

• Side salad – Crisp lettuce, cucumbers, and a simple vinaigrette balance the richness.

• Garlic bread or buttered rolls – Perfect for soaking up extra sauce and melted cheese.

• Steamed green beans or corn – A classic, comforting side.

Tips & Variations

• Pasta shape – Penne, ziti, or cavatappi work just as well as rotini.

• Meatball swap – Use turkey or plant-based meatballs.

• Cheese options – Substitute provolone, Parmesan (sprinkled on top), or a Italian blend.

• Add vegetables – Stir a handful of frozen peas, chopped bell peppers, or spinach into the dish before baking.

• Spice it up – Use arrabbiata sauce or add red pepper flakes.

• Make ahead – Assemble the dish (without baking), cover, and refrigerate for up to 24 hours. Add 10–15 minutes to the covered bake time.

• Leftovers – Store in an airtight container in the fridge for up to 3 days. Reheat in the microwave or oven.
