Storage Tips

You can form the meatballs ahead of time and store them in the refrigerator for up to one day before cooking. For longer storage freeze the raw meatballs on a tray then transfer to freezer bags and cook from frozen adding a few extra minutes. Leftovers keep well in the fridge for up to three days and reheat beautifully in the oven or skillet.

Ingredient Substitutions

If you want to switch up the flavor try using ground chicken or turkey instead of beef for a lighter version. Swap in provolone or fontina cheese for a sharper or more buttery center. You can also use dried spinach in a pinch just rehydrate and squeeze out all excess moisture before mixing in.

Serving Suggestions

These meatballs are incredible over spaghetti with marinara sauce but they also shine on their own with dipping sauces. Serve them on toasted rolls for meatball subs or with a side of garlic bread and salad for a complete meal that feels like a night out. They also work great for parties with toothpicks and warm marinara for dipping.
