Use a fork to puncture the outside of the potatoes several times, around all sides. Steam and pressure build up in the potatoes while they're cooking. Creating several air holes allows the pressure to escape and prevents a potato explosion!
Remove the potatoes from the oven. Gently pierce one of the potatoes with a fork to ensure that they're soft and cooked through. Let cool for about 5 minutes before serving your baked potato (without foil), and enjoy!
