To bake a potato in the oven, the typical cooking time depends on the oven temperature and the size of the potato, but here are common guidelines:

• At 400°F, bake a medium to large russet potato for about 60 to 70 minutes until tender inside and the skin is crispy

. This is a popular temperature that balances cooking time and skin crispiness.

• At 425°F, baking takes about 45 to 60 minutes for the potato to become fork-tender with a crispy skin

• At 450°F, a method involves baking the potato for 25 minutes, then brushing with butter or oil and salt, and baking for an additional 20 minutes, totaling around 45 minutes

• Lower temperatures require longer baking times, for example:
  • 325°F takes about 90 minutes,
  • 350°F takes about 80 minutes,
  • 375°F takes about 70 minutes for a large potato to reach the ideal internal temperature of 205°F to 215°F

General steps include scrubbing the potato, optionally poking holes with a fork, rubbing with oil or butter, seasoning with salt, and baking on a baking sheet or directly on the oven rack

. In summary, baking a medium to large potato in a conventional oven typically takes between 45 and 70 minutes at temperatures ranging from 400°F to 450°F, with 400°F for about an hour being a common and effective method for crispy skin and fluffy interior
