Ingredients & Substitutions
- Penne pasta - Any short pasta will work fine.

- Pasta sauce - Marinara sauce is a good substitute.
- Shredded Mozzarella cheese - Adding Parmesan cheese is also a great addition.
How to make it
To make this meatball casserole recipe, you will want to first fully cook the meatballs and warm the pasta sauce. Boil the pasta according to the package instructions, but leave it a little firm by removing it from the water 1-2 minutes before it reaches al dente.
Add the cooked noodles, meatballs, and pasta sauce to a casserole dish. Give it a good stir and top generously with shredded cheese. Place the meatball casserole in a preheated 425-degree oven for 10-15 minutes.
Once the cheese has melted, remove it and let it cool slightly, then serve with garlic bread.
Storing & Reheating Leftovers
Meatball casserole is best enjoyed fresh out of the oven, but it will store for up to one week in the refrigerator when kept in an airtight container. I recommend reheating leftovers in individual servings in the microwave until warmed through.
