Notes
Storage and Reheating Cool the potatoes completely before storing them in an airtight container in the refrigerator. They’re good to eat for up to 5 days. I don’t recommend freezing the dish since the texture changes considerably when thawed. You can reheat the potatoes in the oven, air-fryer, or a skillet with a light coat of oil. Don’t use the microwave, as it might make the potatoes soggy.
