Easy Meatball Casserole Recipe

Easy Meatball Casserole Recipe with homemade meatballs and covered with melted mozzarella cheese. Perfect on its own, with noodles or in subs!


🌟This cheesy meatball casserole ticks off all of the yummy requirements needed to please everyone in the family. Yes, it’s cheesy goodness but the meatballs are really the star of this dish. They’re moist and crispy on the outside and fluffy on the inside.

🌟One thing you can do to help out future you is make a double batch of Meatballs and freeze the other half. It helps on those nights that you haven’t figured out what to make for dinner and now everyone is starving. No need to panic in that moment, you’ll be one step closer to getting this casserole in the oven.

🌟You can even go one step further and make your own Marinara Sauce. Not only is it super easy to make, it’s more cost effective than buying a premium store bought brand. The flavor is outstanding and worth just the little bit of effort it takes. The recipe yields about 4 cups so you’ll have some left over to use for another dish.


Marinara sauce: Use a good homemade sauce or pick a good store-bought sauce. Good marinara sauce often goes on sale, so you can stock up for when you want to make this later.

Cheese: Be generous with the cheese, we want it to be enough to both melt and to brown on top.

Baking: If your baking pan is broiler safe, you can skip the five minutes of baking at 425 degrees by just turning on the broiler and quickly browning the cheese.


Veggies: Add in cooked broccoli, cauliflower, carrots or any other vegetable your family enjoys.

Meatballs: The meatballs are made from ground beef but you could swap for a ground pork sausage or chicken. Try using turkey meat for a healthier option.


Serve: This casserole shouldn’t be left out at room temperature for longer than 2 hours.

Store: Store any leftovers in a sealed container in the refrigerator for up to 4 days.

Freeze: Once completely cooled, store the casserole in a freezer safe storage bag or container and keep in the frozen for up to 3 months. Allow to thaw in the refrigerator overnight before reheating in the oven.
