Preheat oven to 425 degrees then line a half or quarter sheet pan with foil and place a cooling rack on top. (Alternatively you can bake the potatoes directly on the oven rack - place a sheet pan underneath to catch oil drips.)
Use a fork to make shallow pricks all over the potato (I usually choose 4 "sides" to the potato then make three pricks in each side) then place in a bowl and drizzle with oil and add a big pinch of salt. Rub to evenly coat then place potatoes on prepared baking sheet.
Bake the potato for 50-60 minutes, using tongs to flip the potatoes halfway through, or until a toothpick or knife can be easily inserted into the center. Let cool for 5-10 minutes then serve.
Notes
You can make as many baked potatoes at one time as you like, however the more you bake, the longer they will take. Additionally, if your potatoes are larger than 6-8oz, they will take longer to bake. Using the convection setting on your oven will help speed up the baking process if you are baking several potatoes at a time.
