You can store any leftovers in an airtight container in the refrigerator for up to 3-4 days. I like to reheat them in the air fryer or toaster oven until heated through! To freeze, place the fried and cooled empanadas in a freezer-safe container in the freezer for up to 2 months. I recommend allowing them to thaw overnight in the fridge and then reheating them in the air fryer or toaster oven before serving.
