Dried pepper (You can use black ground pepper)
Steps (Oven-Baked Potatoes).
1. Pre-heat the oven to 400°F. Rub the potatoes with olive oil, sprinkle with salt and ground black pepper. Prick them with a fork. You can either lay them directly on the oven rack or place them on a baking sheet.
2. Cook the potatoes for 45-60 minutes, until the skin is crispy and sticking one with a fork meets no resistance. Baking this way gives crispy potato skins. To have soft skins, wrap the potatoes in foil paper before baking.
