Wash the potatoes and slice thinly using a mandolin, a large slit on a box grater, or a knife. Aim for consistent thickness to ensure even baking.
Soak and rinse the potato slices. Lay the slices on a towel-lined tray and dry with another towel. This step removes some starch from the potatoes, making them less slimy.
Place the potato slices in a bowl and toss with olive oil and salt until well coated.
Arrange the potato slices in a single layer on lined baking sheets. They may touch but should not overlap.
Place the potato slices on the top rack if your oven's heat source is at the bottom. Bake for 15 minutes. Keep a close eye on them to prevent burning.
As soon as the potato slices begin to brown slightly, turn the oven off and let them continue to dehydrate for approximately 30 minutes. Remove any chips that are already crispy.
Remove the chips from the oven and let them cool completely.

Notes
-Cook times vary based on the oven, baking sheet material, and thickness of your potato slices. Keep a close eye on these, as they are prone to burning if you are not careful.
