Preheat the oven to 400°F. Scrub the potato very well under cold water. Pat the potato dry with a paper towel as best you can. Prick the potato all over with a fork, just piercing the skin.
Place the potato on a baking sheet. Brush all over with olive oil. Sprinkle all over with the salt.
Bake for 1 hour or until a toothpick or knife slides in easily with no resistance. If it is not done in an hour I start checking every 10 minutes. Timing depends on how big the potato is, if it is on the smaller side, start checking at 45 minutes.
Slice the top open, pinch the sides and press down and in to open the potato. Fluff the potato insides with a fork, add your favorite toppings such as salt and pepper, butter, sour cream, scallions, cheese, bacon crumbles, etc. Serve immediately.
Notes
Easily double or triple this recipe as this recipe is for one potato.
Top with any of your favorite toppings, see some of my suggestions above.
Make sure you scrub your potatoes and get them as dry as possible, this is what gets them really crispy.
Do not forget to pierce your potatoes or they could explode while baking.
