1. Heat oven to 375 degrees F. Coat a 1-1/2-quart oval (or round) baking pan with nonstick cooking spray.
2. Place a handheld mandoline ($20, available at oxo.com or at kitchen accessory stores) over a large bowl. Place one potato on the slicer, and secure with guard. Using back-and-forth motion, carefully slice potato into 1/8-inch-thick slices. Alternatively, thinly slice potatoes with knife on a cutting board. Repeat with all potatoes.
