What Is A One Pan Meatball Casserole?

One-pan meatball casserole is a baked pasta dish that combines uncooked pasta, raw homemade meatballs, marinara sauce, and cheese, all cooked together in a single baking dish. The result is a casserole-style take on spaghetti and meatballs—only easier and less messy.

Unlike traditional meatball recipes that require browning or simmering, this one simplifies everything. The meatballs cook right in the sauce as the pasta softens and absorbs all the flavor. Using ground beef makes it rich and satisfying, while mozzarella and Parmesan give it that signature gooey finish. Tender meatballs, spaghetti sauce, and lots of cheese transform from simple ingredients to magical dinners the entire family loves.

One Pan Meatball Casserole Ingredients

• Ground beef: Use 80/20 or 85/15 for the best balance of moisture and flavor. You can also mix ground beef with Italian sausage or ground turkey for a different kind of meatballs.
• Breadcrumbs: These help bind the meatballs and keep them tender.
• Parmesan cheese: Adds umami to the meatballs and a salty topping.
• Garlic: Freshly minced garlic gives the meatballs a real boost of flavor.
• Pasta: Penne, rotini, or any short pasta that holds sauce well works great here. Spaghetti squash is a great choice for a low carb option (see bleow).
• Marinara sauce: Use your favorite jarred brand or homemade for a more personal touch.
• Mozzarella cheese: Shreds best when bought as a block, not pre-shredded.
• Water or broth: Helps cook the pasta—broth adds even more flavor.
• Fresh herbs (optional): Basil or parsley adds a fresh finish after baking.

How To Make One Pan Meatball Casserole

1. Preheat the oven to 400°F (200°C).
2. In a large bowl, mix together the ground beef, egg, breadcrumbs, Parmesan, garlic, oregano, onion powder, salt, and pepper until completely combined. I find a dough wihsk or wooden spoon to be helpful with the mixing.
3. Use a large cookie scoop to form the ground beef mixture into 18–20 small meatballs (about 1½ inches in diameter). I find it easiest to place the meatballs a little bit to the side of the bowl so I don’t have to clean another dish.
4. Combine the uncooked noodles, marinara sauce, and water (or broth) in a large baking dish (a 9×13 is a great thing for this). Stir to distribute evenly.
5. Nestle the meatballs on top of the casserole, pressing slightly into the sauce.
6. Cover tightly with foil and bake for 30 minutes.
7. Uncover the casserole, sprinkle mozzarella cheese and Parmesan cheese on top. Then bake unconvered for another 5–7 minutes until the cheese is bubbly and golden. Broil briefly if desired.
8. Remove from the oven and allow the casserole to cool for 5–10 minutes before serving. Garnish with herbs.

Recipe Tips

• Use broth instead of water for extra depth in the pasta.
• Let it rest after baking so the casserole sets and doesn’t fall apart when serving.
• Broil the top for 2–3 minutes at the end for a bubbly, golden cheese finish.
• Store leftover casserole in an airtight container in the fridge for up to 4 days. Reheat individual portions in the microwave or reheat larger portions covered in the oven at 350°F (175°C) until warmed through.

Slow Cooker One Pan Meatball Casserole

To make this in a slow cooker, start by mixing your meatball ingredients and rolling them into balls. In the slow cooker, layer the uncooked pasta, marinara sauce, and water (or broth), then add the raw meatballs, making sure they’re covered by the sauce. Cook on low for 4–5 hours or high for 2–3 hours until the pasta is tender and the meatballs are fully cooked. About 30 minutes before serving, top with shredded mozzarella and optional Parmesan, then cover and let the cheese melt. It’s a set-it-and-forget-it meal that delivers all the flavor with minimal effort!

One Pan Meatball Casserole Variations

• Spicy meatball parmesan: Add crushed red pepper flakes to the meatballs or sauce for extra heat. You can also use a spicy marinara and extra parm.
• Cheesy twist: Mix ricotta cheese into the pasta layer or add sliced provolone along with the mozzarella for a creamy finish.
• Vegetable version: Stir in chopped spinach, mushrooms, or zucchini with the pasta and sauce before baking for added nutrients.
• Turkey meatballs: Substitute ground beef with ground turkey for a lighter, leaner casserole. 
• Italian meatballs: For a true Italian flair, add finely chopped fresh basil and parsley to the meatball mixture, and season with a pinch of red pepper flakes and Italian seasoning.
• Keto meatball casserole variation: Skip the pasta and bake just the meatballs in marinara sauce. While it bakes, roast halved spaghetti squash (cut side down at 400°F for about 40 minutes), then serve the meatballs and sauce over the roasted strands. Top with the delicious shredded cheese.
