Ingredients You’ll Need
What makes this Dump and Bake Meatball Casserole so magical is how it transforms simple, everyday ingredients into a bubbling, cheesy masterpiece. Each component adds its own special touch, from the hearty pasta to the final sprinkle of fresh herbs.
- Uncooked penne or ziti pasta (1 16-ounce package): Sturdy shapes like penne or ziti hold up beautifully in the oven and soak up all the savory sauce, so skip the delicate noodles here.
- Marinara sauce (1 24-ounce jar): Choose your favorite jarred brand, or go homemade if you have a batch on hand—the sauce is the flavor backbone of this casserole.
- Water (3 cups): Essential for cooking the pasta right in the baking dish; it melds with the sauce for that perfect texture.
- Frozen fully cooked meatballs (1 14–16-ounce bag): No need to thaw—just dump them in! They add protein and loads of flavor with zero fuss.
- Shredded mozzarella cheese (2 cups): For that gooey, stretchy, irresistible cheese pull on every forkful.
- Grated Parmesan cheese (1/4 cup): Adds a savory, nutty finish that brings everything together.
- Italian seasoning (1 teaspoon): A fragrant blend that gives your casserole that classic, herby Italian flavor.
- Salt and pepper to taste: Don’t forget to season—the right amount of salt and pepper makes all the flavors pop.
- Chopped parsley or basil for garnish (optional): Fresh herbs add a burst of color and a touch of brightness right before serving.
How to Make Dump and Bake Meatball Casserole
Step 1: Prep the Baking Dish
Start by preheating your oven to 425°F. Grab a large 9×13-inch baking dish; this will give your pasta plenty of room to expand as it cooks and ensures even baking. No need to grease—just pull out your favorite casserole dish and get ready to build layers of flavor.
Step 2: Combine the Pasta, Sauce, and Seasonings
Pour the uncooked pasta straight into the dish, followed by the entire jar of marinara sauce and the 3 cups of water. Sprinkle in the Italian seasoning and a good pinch of salt and pepper. Give everything a thorough stir so the pasta is evenly coated and nothing is left dry—this helps every bite turn out perfectly tender.
Step 3: Add the Meatballs
Take your bag of frozen meatballs (no thawing needed!) and arrange them evenly over the pasta mixture. Gently press them down so they’re nestled into the sauce. This way, they’ll absorb plenty of flavor and heat through beautifully in the oven.
Step 4: Cover and Bake
Tightly cover the dish with aluminum foil to trap in steam and help the pasta cook evenly. Slide it into your preheated oven and bake for 35 minutes. This is the perfect time to tidy up, prep a quick salad, or simply put your feet up!
Step 5: Add the Cheese
After 35 minutes, carefully remove the foil (watch out for steam!). Give the pasta a gentle stir—this helps redistribute everything for even cooking. Sprinkle the mozzarella and Parmesan cheeses generously over the top, then return the casserole to the oven uncovered.
Step 6: Finish Baking
Bake for another 10 to 15 minutes, or until the pasta is perfectly tender and the cheese is melted, golden, and bubbling. Let the casserole rest for 5 minutes before serving so everything can set up a bit—this makes for cleaner slices and happier eaters.
How to Serve Dump and Bake Meatball Casserole

Garnishes
A final sprinkle of chopped fresh parsley or basil adds a pop of color and a hint of freshness that really brightens up the dish. If you like a little extra kick, a dusting of crushed red pepper flakes or a drizzle of good olive oil takes it over the top.
Side Dishes
This hearty Dump and Bake Meatball Casserole pairs perfectly with a crisp green salad tossed in Italian vinaigrette, garlicky roasted vegetables, or simply some warm, crusty bread to mop up all that saucy goodness. For a classic Italian-American meal, a side of steamed broccoli or green beans rounds things out beautifully.
Creative Ways to Present
For a fun twist, try serving individual portions in mini casserole dishes or ramekins—perfect for dinner parties or potlucks. You can also spoon the casserole onto toasted hoagie rolls for a meatball sub-inspired dinner, or serve it with a scoop of ricotta on top for an ultra-creamy finish. The possibilities are endless with this crowd-pleaser!
Make Ahead and Storage
Storing Leftovers
Leftover Dump and Bake Meatball Casserole keeps beautifully in the fridge. Simply let the casserole cool, then cover the dish tightly or transfer portions to airtight containers. It will stay fresh for up to 4 days—making it a fantastic option for meal prep or next-day lunches.
Freezing
This casserole is wonderfully freezer-friendly. Once baked and cooled, portion into individual containers or freeze the whole dish tightly wrapped. When ready to eat, thaw overnight in the refrigerator for best texture. It’s a lifesaver on hectic days!
Reheating
To reheat, simply cover and bake leftovers in a 350°F oven until warmed through, or microwave single servings for 2–3 minutes, stirring halfway. If the pasta looks a little dry, add a splash of water or marinara before reheating to bring back that saucy goodness.
