Ingredients You’ll Need

• Rotini pasta (1 box, 16 oz): Its spiral shape is ideal for holding onto sauce and cheese, ensuring every bite is flavorful.
• Water (3 cups): Essential for cooking the pasta right in the casserole dish without needing to boil separately.
• Pasta sauce (1 jar, 24 oz): A rich and tangy tomato base that infuses the entire casserole with vibrant flavor.
• Frozen precooked meatballs (1 bag, 14 oz, thawed): The star protein of the dish, already cooked to save you time while adding satisfying heartiness.
• Kosher salt (1 teaspoon): Enhances and balances all the flavors.
• Shredded mozzarella cheese (2 cups): Melts into a gooey, golden topping that brings creamy indulgence.

How to Make Dump and Bake Meatball Casserole Recipe

Step 1: Prep Your Oven and Dish

Start by preheating your oven to 425° F, creating the perfect baking environment for this hearty casserole. While it warms, grab a 9×13 baking dish and spray it generously with cooking spray. This step ensures the casserole won’t stick, making clean-up a breeze and keeping every portion intact when serving.

Step 2: Combine All Ingredients in the Baking Dish

Here’s where the beauty of the Dump and Bake Meatball Casserole Recipe shines — no need to boil pasta or brown meatballs ahead. Simply dump the uncooked rotini pasta into your prepared dish, then add the water, the jar of pasta sauce, thawed meatballs, and kosher salt. Give the pan a quick stir to evenly distribute everything before covering tightly with tin foil. This sets the stage for all those lovely flavors to meld in the oven.

Step 3: Bake and Stir Midway

Pop your covered casserole into the oven and bake for 35 minutes. Halfway through baking, uncover the dish carefully and give everything a good stir. This helps the pasta cook evenly and prevents sticking, while also redistributing the meatballs and sauce for balanced flavor in every bite.

Step 4: Add the Cheese and Finish Baking

After stirring, sprinkle the shredded mozzarella cheese evenly over the top of the casserole. Return the dish to the oven uncovered and bake for an additional 5 to 8 minutes, just until the cheese is melted and bubbling deliciously. That golden blanket is not just beautiful to look at but elevates the entire dish to melt-in-your-mouth comfort food status.

Step 5: Serve and Enjoy

Once your cheese-topped casserole is out of the oven, give the pasta a final gentle stir to incorporate pockets of melted cheese with meatballs and sauce. It’s now ready to serve — warm, hearty, and irresistible.

How to Serve Dump and Bake Meatball Casserole Recipe

Garnishes

Adding a sprinkle of freshly grated Parmesan cheese or a handful of chopped fresh parsley can instantly brighten and elevate your casserole. These garnishes provide a lovely contrast in texture and a pop of fresh flavor that complements the rich, cheesy meatball base well.

Side Dishes

This casserole pairs wonderfully with simple, light sides to balance its heartiness. Consider a crisp green salad with tangy vinaigrette or some roasted vegetables like broccoli or asparagus. Garlic bread or crusty rolls are also fantastic for sopping up the luscious sauce.

Creative Ways to Present

For a fun twist, serve the Dump and Bake Meatball Casserole Recipe in individual ramekins or mini cast-iron skillets for personalized portions. You can also layer with extra cheese or sprinkle red pepper flakes on top for those who love a little heat. Making it a buffet-style dish with assorted toppings lets everyone customize their own slice of comfort.

Make Ahead and Storage

Storing Leftovers

Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. Be sure to let it cool completely before sealing to maintain texture and freshness. When ready to enjoy again, leftovers reheat perfectly with a little moisture added to prevent drying out.

Freezing

If you want to prep ahead, this Dump and Bake Meatball Casserole Recipe freezes beautifully. Assemble everything but hold off on baking, then cover tightly with foil and plastic wrap before freezing for up to 2 months. When ready, thaw overnight in the fridge before baking as usual, adding the cheese topping near the end.

Reheating

To reheat, warm individual portions in the microwave or reheat the entire casserole covered with foil in a 350° F oven until heated through. Add a sprinkle of shredded mozzarella during reheating to freshen up that gooey, melty texture everyone loves.

FAQs

Can I use a different type of pasta?

Absolutely! While rotini works great because it holds sauce well, other short pasta shapes like penne or rigatoni will work equally well, as long as you adjust cooking time slightly if needed.

Do I have to thaw the meatballs before baking?

Thawing precooked meatballs is recommended to ensure even heating and prevent overly long bake times. If cooking from frozen, expect the casserole to take extra time in the oven, and check doneness carefully.

Can I make this casserole vegetarian?

Yes, simply swap the meatballs for vegetarian or plant-based meatball alternatives, or even roasted vegetables like mushrooms and zucchini for a hearty vegetarian version.

Is it possible to use homemade pasta sauce?

Definitely! Homemade pasta sauce can add an extra layer of freshness and control over flavors — just use about 24 ounces to maintain the right balance in the casserole.

What if I don’t have kosher salt?

You can substitute table salt or sea salt, but reduce the amount slightly since kosher salt is less concentrated. Start with ¾ teaspoon and adjust to taste.
