I experimented with this recipe with my mother because I wanted to make a homemade snack for my children.

Use parchment paper, not paper towels. If you slice the potato too thinly, the chips won't have much texture. Also, when you put the slices on the paper, make sure the slices do not overlap or they'll get stuck to each other!
Try peeling the slices off the paper occasionally or turning them for best results.
The potato chips may not crisp up enough in a 500 W oven, so test it out yourself. Recipe by shokolat
