Baking potatoes at 0°F is not practical or effective, as this temperature is below freezing and will not cook the potatoes. Typically, potatoes are baked at much higher temperatures, usually between 375°F and 425°F. Here are standard baking guidelines for potatoes:

• At 400°F, bake medium-sized potatoes for about 60 to 80 minutes until the skin is crisp and the inside is tender, with an internal temperature of 200 to 210°F for optimal fluffiness

• At 425°F, small potatoes take about 35-45 minutes, medium potatoes 45-55 minutes, and large potatoes 55-70 minutes

• Lower temperatures like 350°F will require about 60 to 90 minutes depending on size

In summary, baking potatoes at 0°F is not feasible. Instead, bake them at 375-425°F for 45 to 90 minutes depending on size, until tender and easily pierced with a fork
