Preheat an oven to 400°F. Line one baking sheet with parchment paper for each variety of chips you are making, set aside.
Using a mandoline slicer or a sharp knife, cut potatoes into thin discs (as thin as you can get them).
Transfer slices to paper towels. Cover with a second paper towel and press down to force out as much moisture as you can.
In a large bowl, combine olive oil and dry ingredients for whichever flavor you are mixing. Toss in potato slices, coating well. Transfer to parchment lined baking sheet.
Bake for 15-25 minutes. Begin checking potatoes at 15 minutes, removing any that are done. Drain on paper towels. Return remaining potatoes to oven until crisp.
