Yes, to freeze, place the unbaked empanadas on a parchment lined baking sheet and flash freeze until the dough has mostly hardened. Flash freezing prevents the empanadas from sticking together. Remove from freezer and place the empanadas in a large ziptop bag or air-tight container and freeze for up to 3 months. You can allow them to thaw before baking, or bake straight from frozen, adding extra time in the oven as needed.
