Can I use dried pasta other than rotini?

Absolutely. Penne, fusilli, or even shells work well in this recipe. Just stick to short pasta shapes so they cook evenly—the important thing is not to overcook.

Can I use homemade meatballs instead of frozen?

Yes! If you have cooked, homemade meatballs, they are fantastic here. Just make sure they are fully cooked before adding and are about the same size as store-bought for even baking.

How can I make this vegetarian?

Simply use vegetarian meatballs (found in the freezer section) or replace the meatballs with balls of seasoned ricotta for a cheesy alternative. Mix in cooked veggies for extra substance.

Can I prepare this casserole in advance?

Yes, for convenience you can assemble everything except the cheese a few hours ahead and refrigerate. When ready to bake, let it sit out for about 20 minutes to take off the chill, then follow the baking instructions. Add cheese in the final minutes as usual.

How to Make Dump and Bake Meatball Casserole

Step 1: Prep Your Baking Dish

Preheat your oven to 425°F and spray a 9×13-inch baking dish with cooking spray to keep sticking at bay.

Step 2: Layer the Ingredients

Pour the uncooked rotini pasta straight into the dish—it feels counterintuitive but trust the process! Add the water and dump in your favorite pasta sauce, making sure it coats the pasta well. Scatter the thawed meatballs evenly, sprinkle in the salt, and mix it all gently to spread everything out.

Step 3: Cover and Bake

Seal the dish tightly with tin foil. This traps steam inside, cooking the pasta perfectly while keeping it from drying out. Bake for 35 minutes, and about halfway through, carefully stir everything so the pasta cooks evenly in all those luscious juices.

Step 4: Add the Cheese

Uncover, stir again for good measure, then lavish the top with shredded mozzarella. Return to the oven uncovered for 5–8 minutes, just until the cheese is bubbling and golden.

Step 5: Serve and Enjoy

Let the casserole cool for a few moments to make serving easier. Top with grated parmesan or fresh parsley for an extra flourish.

Note: The pasta keeps soaking up sauce as it sits, so don’t be shy with the sauce if you love things extra juicy.

Pro Tips for Making the Recipe

Thaw Meatballs Well: If they’re still icy, they can bring down the casserole’s temperature and throw off the cooking time.
Stir Halfway: This is the secret to even pasta coverage and no gummy bits.
Generous Cheese Layer: For best results, pile the mozzarella high. Want that stretchy, pizzeria-style cheese? Let it broil for an extra minute or two.
Don’t Overbake: Once the pasta is just tender and the cheese is melted, pull it out, or you risk mushy noodles.

How to Serve

This casserole is irresistible straight from the dish—just add a big green salad or some crisp garlic bread to complete the meal. Pair with a simple Caesar, steamed broccoli, or a bright tomato salad for freshness. For a weekend treat, serve alongside a glass of Italian red wine or sparkling lemonade. Want to stretch leftovers? Try tucking spoonfuls into a warm hoagie roll for a meatball sub twist.

Make Ahead and Storage

Storing Leftovers

Cool any extras to room temperature, then cover and refrigerate for up to 3 days. The flavors deepen overnight, making amazing leftovers.

Freezing

This casserole freezes beautifully. Simply wrap tightly (foil and then plastic wrap) and store for up to 2 months. You can freeze the whole dish or portion into single servings for lunchboxes.

Reheating

To reheat, microwave individual portions until steaming hot, or cover the whole dish with foil and warm in a 350°F oven until bubbly. Add a splash of water if it seems dry.

Note: If reheating from frozen, thaw overnight in the fridge before baking or microwaving.
