01 - Wash apples thoroughly and remove cores using an apple corer or sharp knife. Slice apples crosswise into thin rounds approximately 1/8 inch thick using a mandoline slicer for uniformity.
02 - Pat apple slices dry with paper towels to remove excess surface moisture, which helps achieve crispier results.
03 - Place apple slices in a single layer in the air fryer basket without overlapping. Work in batches if necessary to ensure proper air circulation and even cooking.
04 - Lightly spray or brush slices with oil if desired. Sprinkle ground cinnamon evenly over all apple slices. Add coconut sugar or maple sugar if using extra sweetness.
05 - Air fry at 325°F for 12 to 15 minutes. Flip all slices after 7 minutes for even cooking. Monitor closely during the final minutes to prevent burning as cooking times vary by apple variety and thickness.
06 - Remove golden crisp chips from air fryer and transfer to a wire rack. Allow chips to cool completely as they will continue crisping during the cooling process.
