I, wasn’t sure and skeptical, but it turned out to be one of best tries.
Utilizing a mechanism of the microwave, it warms food by using the moisture in the food itself. So that potato slice rapidly dried and becomes crunchy.
Prepare potatoes as many as you like to eat, slice them as thin as you can.
E.g. two potatoes takes, 600W x six to seven minutes x three times, = about 21 minutes to be served.
Two ziploc containers at last. One container for One potato x 2.
*a slicer would be useful but not necessary. I sliced with a regular kitchen knife.
And neatly place the sliced potatoes on a cooking paper, avoid overlapping.
Put the paper in the microwave.
600W x six to seven minutes.
No regret, as the result is very satisfying.
Open once, check how much potatoes have dried, do more minutes to dry completely.
You’ll see potatoes start changing the color to brown.
Take the paper out, leave it for a while.

Repeat the microwave drying as you need.
For this process there is no shortcut unless you have a huge microwave or multi microwaves.
No oil, no salt, homemade tasty crunchy potato snack is ready.
bon appetit!

Sliced very thin, like potatoes. Maybe because sweet potato contains less moisture? It was different from potatoes. I burned some… potatoes would better suit than sweet potato for chips.
