One Pan Meatball Casserole is one of those dump it and forget it family favorites that everyone loves. It makes a great freezer meal and I've adapted it for the slow cooker and instant pot.
One pan dishes are the kind of recipes that motivate me to make dinner. I love the thought of few dishes and easy prep! Some of my favorite one pan meals include Easy Beef Stroganoff, Cottage Pie, and One Pan Jambalaya.
This is one of those magical dinners where uncooked noodles, sauce, and meatballs are all added to a casserole dish and baked together in the same pan! It doesn't get much easier then that, and it's the type of warm and comforting meal that everyone in your family will love!
Ingredients you'll Need:
- Uncooked ziti pasta: or penne noodles
- Marinara sauce: homemade or store-bought
- Milk: makes it creamy, but additional water or broth can be substituted.
- Water
- Spices: garlic powder, onion powder, oregano, and salt
- Cooked meatballs: I like to use my homemade chicken meatballs.
- Shredded mozzarella cheese
- Optional toppings: parmesan cheese and fresh chopped herbs (such as basil, oregano, and parsley for garnish)
How to Make Meatball Casserole:
- Mix. In a large baking dish stir together uncooked pasta, marinara sauce, water, milk, spices and meatballs.
- Bake. Cover tightly with aluminum foil and bake at 425 degrees F for 40 minutes.
- Stir and check. Check the pasta—we want it to be al dente (firm, but almost perfectly cooked). If it’s still too hard, cover the dish and return to the oven for a few minutes.
- Add cheese. Sprinkle mozzarella over the top and bake uncovered at 425 degrees F. for 5-10 more minutes or until cheese is melted and bubbly.
- Serve. Allow to cool for at least 15 minutes before serving, to allow the sauce to thicken up.
Want to make a smaller batch? Cut the recipe in half and bake in an 8’’ or similar size dish.
Can I use frozen meatballs? I suggest thawing the meatballs first, so that everything bakes in as quick of time as possible. If you bake the dish with frozen meatballs it will take longer to bake.
Slow Cooker: Prepare as directed, but leave out the milk and add an additional 24 oz jar of marinara sauce. Be sure the ziti noodles are covered with sauce. Cook on HIGH for 2 – 2 ½ hours, or LOW for 3 ⅓ -4 hours or until pasta is tender. Sprinkle mozzarella cheese on top during the last few minutes of cooking and return the lid to allow the cheese to melt. Optional: place under broiler for a few minutes to toast the cheesy top.
Instant Pot: Here is my very similar Instant Pot version. https://tastesbetterfromscratch.com/instant-pot-penne-pasta-with-meatballs/
Make Ahead Instructions: This meatball casserole can be assembled completely the night before, but I wouldn’t do it any sooner than that or the noodles may have a mushy texture after baking.
Freezing Instructions: Prepare the meatball casserole up until baking. Cover with a double layer of aluminum foil and freeze for up to 3 months. Thaw in the fridge before baking, or to bake from froze, baked covered for 1 hour and 30 minutes, and uncovered for 15-20 minutes longer.

I wish the recipe would say how many meatballs approximately.
Can you use uncooked meatballs
I would cook the meatballs in a skillet first.
This is my family’s new favorite. We love it so much, I always have the ingredients handy in case visitors showed up unexpectedly. It’s super easy and delicious. Thanks for the recipe.
Really great and easy recipe! It was the delicious comfort food I was looking for, although because my husband isn’t a huge fan of marinara sauce I replaced it with alfredo sauce which still worked great. Thanks for your recipes!
So yummy!!! This was super easy to make, super delicious and since it’s just me and my husband we had leftovers for daysss! Haha, literally this recipe made enough for us to each have 5 servings.
The cooking time seems appropriate for raw meatballs. Can you do that? Doesn’t using pre-cooked meatballs make them dry out?
I was wondering the same thing
I like to make my own meatballs fresh
We just made this last night. It was so delicious! A family favorite! We will make it again soon!
so easy!
Approximately how many meatballs are needed for the recipe?
Yes, I’m curious about this too!
I’m using about 30 frozen meatballs tonight!
I’d like to know too! In the photo and video I count 18-20. But I’m not sure if they’re the 1/2 oz. or 1 oz. size meatballs. They appear big though so maybe 1 oz. balls!
If you can’t use milk, would you use 3 cups water total? (I noticed there were already 2 cups of water in the recipe. Thanks for the help.
Yes 🙂
