Preheat oven to 350F. Place a wire rack inside of a rimmed baking sheet and spray lightly with a nonstick spray.

Use a mandoline to make really thin slices of apple. There is no need to core and peel the apple but make sure you remove any seeds.

Bring the sugar and water to a boil in a saucepan. Add the apple slices and cook, stirring frequently, for about 10 minutes or until the slices are translucent. Use tongs to remove the slices from the syrup and place them on the wire rack in a single layer. (You can discard the syrup or save it - it's amazing apple-flavored simple syrup!)

Bake for about 15-20 minutes, or until they're golden.The chips may not be crisp at this point but they will crisp up almost as soon as you pull them out of the oven. Transfer the chips to a sheet of wax paper and let them cool completely.
