preheat oven to 400 degrees. Stab the potatoe about 6 times with a fork (make sure its washed off first). then cook it for 45-55 minutes. just a side note- if you cook it in a microwave it will be done in about 5 minutes.The instructions are in the name really, simply put the potato in the oven. A temperature of 375 to 400 for 30-45 minutes should do you just fine, depending on the size of the potato. DO NOT POKE HOLES OR WRAP THEM! Both of these poor suggestions will only serve to dry out your potato. The already come with a skin, just throw them on the rack. Happy eating!
