How can I quickly prepare a fast baked potato in the oven?

To quickly prepare a fast baked potato in the oven, first preheat the oven to 425F. Wash the potato, poke holes in it with a fork, and rub it with oil and salt. Place it directly on the oven rack and bake for about 45-60 minutes, or until it is soft when pierced with a fork. Enjoy with your favorite toppings!
