Peel & slice 3 smaller sweet potatoes as thin as you possibility can. A mandolin or Pandero Spiralizer {Using The Slicing Attachment} works really well for this.
If you have the time, soak them in room-temp water for an hour, then dry well. This step ups the crunchiness factor.
Preheat oven to 450 degrees f
Combine & coat well.
Spread potatoes onto a flat sheet pan, in a single layer.
They will not crisp if they are piled up.
Bake in a preheated 450 degree oven for about 12 minutes per side (flipping once).
Enjoy <3
