We recommend baking potatoes at 400 degrees F for about an hour. Smaller spuds might take a little less time, while larger baking potatoes over 1 pound might take a little more. For a fully baked Idaho Russet Burbank, the internal temperature should be right at 210 degrees F. In foodservice, where the baked potato will be kept warm after it comes out of the oven, we recommend the internal temp to be 185 degrees F as the potato will continue to cook.
