Here is a step-by-step tutorial on how to oven bake potatoes:
1. Preheat the oven to 425°F.
2. Wash the potatoes well, dry with a paper towel, and rub (or use a brush) with olive oil and salt and pepper.
3. Prick the skins of the potatoes with a fork.
4. Bake for 45-50 minutes or until the skin crisps and puffs and the potatoes are easily pierced.
5. Remove from the oven and let cool for 5 minutes before cutting open.
You can also bake potatoes in a convection oven by following these steps:
1. Preheat the convection oven to 375°F.
2. Rub the potatoes with a nylon brush under flowing water to wash away dirt. Pat a soft cloth to dry.
3. Prick the potatoes 6-8 times with a fork or a thin rod.
4. Rub down oil and salt on the potatoes.
5. Place the marinade potatoes on the middle oven rack.
6. Bake them for 45-50 minutes.
