Scrub potatoes and pat dry. Slice potato into thin chips; you can use a mandolin slicer to get uniform slices or cut by hand into ⅛- to 1/16 -inch-thick rounds. Soak slices in cold water for about 20 minutes; this will help get achieve a nice crispy chip at the end.

Preheat oven to 300˚. Line a baking sheet with parchment paper or liberally coat a baking sheet with nonstick oil spray. Place slices on prepared baking sheet in a single layer (don’t let them overlap), mist tops with oil spray and sprinkle on salt.

Bake in the oven for about 40 minutes or until chips are browned and crispy. Depending on the thickness of your chips, you may have to cook them longer (up to 80 minutes for thicker slices). Just keep checking and testing for crispy perfection.
