Storage and Reheating Tips

Store leftover burger patties in an airtight container in the refrigerator for up to 3 days. Reheat the patties in a hot skillet for the best texture. Avoid microwaving if possible as it can soften the crust. Toast fresh buns and assemble the burger just before serving for the best flavor and texture.
