Some of you know about my microwave experiments driven by curiosity. Last week I set out to make potato chips. You can imagine my surprise when the microwave produced crispier results than the oven. Since it worked so well with regular potatoes I decided to give sweet potatoes a try as well.
Sweet potato fries usually fall on the softer side, so I expected limp, soggy slices instead of chips. Once again the microwave produced crunchy chips, even without oil. All you need are sweet potatoes, a microwave with a turntable and parchment paper. Oh, and the time and patience to watch the microwave action carefully. If you don't babysit these little guys, they can go from a crispy crunch to carbon rather quickly.
When making french fries it helps to soak the potatoes in cold water to remove some of the starch. I tried soak and no-soak methods for the chips and liked the results better without the soaking (not to mention the saved time and clean-up). While soaking isn't important here, how you slice the potatoes is key. I wouldn't suggest using a knife, it's just too difficult to get even pieces. Each slice needs to be thin and uniform or you'll end up with soggy pieces of potato next to scorched chips. Use a mandolin slicer or equivalent attachment to get the chips as thin as possible, about 1 to 2 millimeters. I'm not quite sure what mine is called, but I used the old metal slicer pictured below. You may be able to use a food processor attachment, but it really depends on the thinness your blade can achieve. Sorry, I know that's annoying and unhelpful.
Microwave Sweet Potato Chips
1 sweet potato
* Using a mandolin slicer, slice sweet potato into very thin chips, 1-2 millimeters. I don't recommend trying this with a knife as it is difficult to get them both even and thin enough.
* Place a piece of parchment paper on a microwave-safe plate. Spray lightly with nonstick baking spray. Place one layer of sweet potato chips over parchment, making sure chips do not overlap. Sprinkle with salt. Using a microwave** with a turntable, microwave on high for 2-1/2 to 3 minutes or until centers of a few chips just begin to brown.
* Flip chips over, rotating the chips in the center with chips on outside of the plate. Continue microwaving and watching closely for 30 second intervals, rotating chips as needed for even browning. Within 1-2 more minutes chips should be stiff and crispy, but not chewy. Chips will crisp slightly upon standing. Repeat with remaining potato slices.
**This recipe was tested using an 850-watt microwave. Times will vary greatly depending on the power of your microwave and the size of sweet potato slices.
