I was making a big pot of Beef Stew last night and knew that I had more potato than I needed, so an idea popped into my head ... it's so easy to make beet chips in the microwave, what would happen if I tried potatoes?? Since I was just experimenting, I didn't bother whipping out the mandoline. I just sliced the potato as thin as I could with the knife I was using.
I placed the slices on a paper plate and gave them a light sprinkle of salt, then popped them in the microwave for 2 minutes, flipped them, salted the other side, popped them back in for another 2 minutes, then flipped them and popped them back in for another 2. That's it!
The only "problem" I had was that when I went to flip them the first time, a few of the edges had stuck to the plate. They have a shine to them like a rice cracker, but they taste like baked potato chips. The thinner slices came out very crispy, the thicker ones a little softer, but I didn't bother putting them back in. I'll try this again using the mandoline next time for consistent slices. Maybe I'll experiment with flavors.
As for beets, you need to keep a very close eye on them once the moisture gets sucked out of them, because they will burn very quickly. I have made the beet chips a few times, but don't think I paid attention to the time - just watched and flipped until they were done.
