Soon after I started using my Paderno vegetable slicer in 2015 to cut sweet potatoes into curls, I bought an oven crisper pan. This thing is great. Instead of drenching the slices in hot oil to fry them, I just put them in a bowl, add a bit of salt and olive oil and stir until the slices are lightly coated.
The capacity seems to be two medium size sweeties. I put the pan in the oven at 400F and let them bake for about 10 minutes, then flipped them with a spatula every five minutes until they looked done.
The slices shrink a lot, because the water gets baked out. The photo above shows what two sweet potatoes look like after baking. My wife and I ate all of them so I made another batch from two more sweeties. We ate that, too. We could have gone for thirds, but became concerned that our skin would turn orange.
Clean up is easy — wipe it with a moist paper towel.
