The ideal cooking temperature for baked potatoes is between 350 and 425 degrees Fahrenheit. When cooked at the higher temperature range, potatoes develop skins that are crispier than those cooked at lower temperatures.
Always scrub potatoes thoroughly before baking to remove any excess dirt on the skins. Puncture the skin four to five times with a sharp knife or fork to let steam escape during the baking process so that the potato does not burst. Cooking time will vary depending on the size and shape of the potato, but most potatoes take roughly one hour. When fully cooked, the potato will feel soft when gently squeezed or poked with a knife.
