- Olive-oil cooking spray
- 1 (8-ounce) russet (baking) potato
- Preheat oven to 400°F. Lightly coat a large baking sheet with cooking spray.
- Peel potato and cut crosswise into paper-thin slices with a mandoline or other manual slicer. Overlap 8 to 10 slices on baking sheet to form a 4-inch round and make 7 more rounds in the same manner. Spray rounds lightly with cooking spray and season with salt and pepper.
