Tips for the meatball casserole recipe

This cheesy meatball casserole is a fast and easy dinner option that’s 100% sure to please the whole family! Here are a few tips for tweaking it to your taste.

  • You can also mix 1 lb (450g) ground beef and 1 lb (450g) spicy pork sausage instead of using ground turkey.
  •  We use a high-quality store-bought marinara sauce for this meatball casserole recipe, feel free to use whatever variety of sauce you prefer. 
  • This meatball casserole recipe is adaptable to a Crockpot. Follow the recipe instructions but instead of layering them into a baking dish, simply layer the meatballs into a slow cooker instead. Cook on low for 6 hours.

How and how long to keep the meatball casserole leftovers?

Store any meatball leftovers in a sealed container in the refrigerator for up to 4 days. If you wish to freeze the cooked meatballs, keep them in a freezer-safe storage bag or container and keep them frozen for up to 3 months. Allow thawing in your refrigerator overnight before reheating the meatballs in the oven.

    Did the recipe as stated, used a cast iron skillet to brown the meatballs first then added the marinara sauce and mozza cheese on top, put the skillet in oven at 400 degrees for 20-25 minutes. Delicious!

    I made this tonight as per recipe apart from I cooked some onion and added it to the turkey before making the meatballs. I have made lots of meatballs in the past but have always found they lacked flavor. These were delicious and will definitely be added to my meal rotation. I served with stir fried garlic green beans and brussel sprouts and the whole family loved.
