Seasoning of your choice -smoked paprikaonion powder, etc.
Using a mandolin, slice the potato into very thin slices, with or without the peel.
If using the oven
Preheat oven to 400F
Line a baking sheet with parchment paper
Arrange the potato slices in a single layer on the parchment lined baking sheet
Sprinkle the tops with sea salt, along with any other seasonings that you prefer
Bake in the center of the oven for 10 minutes.
After 10 minutes, the edges will begin start to crisp and curl up. Flip each chip over, and return to the oven for another 2-3 minutes, or until desired crispness is reached. *You must continually watch them after you turn them over because they can go from crisp to charred in a matter of minutes.
If using a dehydrator
Arrange the slices into a single layer on the mesh trays, and dry at 155F (High) for approximately 2-3 hours, or until desired crispness is reached.
