Preheat oven to 200–220 F

Core and slice the apple into thin rounds about 1/8-inch to 1/16-inch.

Spread evenly on two baking sheets.

Bake for 30 minutes.

Flip the apples over.

Continue baking until they are dry and slightly crisp to the touch.

You will want to remove the thinner pieces and let the thicker ones continue drying out until just crisp and not moist.

TIPS:
Golden Delicious or Granny Smith would work nicely.
