Storage and Reheating Tips

Store leftover cooked patties in an airtight container in the refrigerator for up to 3 days. Reheat the patties in a skillet over medium heat until warmed through to maintain the crispy edges. Burger sauce can be stored in a sealed container in the refrigerator for up to 5 days. For best results, assemble burgers fresh before serving.
