With a stiff brush, scrub your potatoes until they are very clean. Then, make sure that they are dry.
Line a baking sheet with foil or parchment paper and then coat each of your potatoes with about a tablespoon of olive oil per potato.
Coat your potato with salt. Again, make sure to rub the salt all over each one. This usually takes about 1/2 to 1 teaspoon per potato, depending on the size.
You’ll also want to use a fork and prick each one about six to eight times to allow air to escape as they bake.
Then, arrange the potatoes on the parchment or foil-lined baking sheet that has been fitted with a wire rack. Set it on the middle rack of your oven.
