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!
One Pan Meatball Casserole
One Pan Meatball Casserole is an easy, dump it and forget, family favorites. I’ve included options for making it in the slow cooker or as a freezer meal!
Ingredients
- ▢16 oz. package uncooked ziti pasta
- ▢24 ounces marinara sauce
- ▢1 cup milk
- ▢2 cups water
- ▢1/2 teaspoon garlic powder
- ▢1/2 teaspoon onion powder
- ▢1 teaspoons oregano
- ▢1 teaspoon salt
- ▢Meatballs , fully cooked, thawed
- ▢2 cups shredded mozzarella (or Italian blend cheese)
- ▢Optional: Parmesan cheese and fresh chopped herbs (such as basil , oregano, and parsley for garnish)
Instructions
- Preheat oven to 425 degrees F.
- In a 9×13 inch baking dish stir together uncooked pasta, marinara sauce, water, milk, spices and meatballs.
- Cover tightly with aluminum foil and bake for 40 minutes.
- Uncover; stir. Check the pasta for doneness. 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.
- Sprinkle mozzarella over the top and bake uncovered for 5-10 more minutes or until cheese is melted and bubbly.
- Allow to cool for at least 15 minutes before serving, to allow the sauce to thicken up.
Notes
Want to make a smaller batch? Cut the recipe in half and bake in an 8’’ or similar size dish.
Make Ahead: This recipe 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 recipe 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.
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.
