Step 1

Wash and peel 4 medium sweet potatoes.

Step 2

Slice the sweet potatoes between ¼ and ½-inch thickness.

Step 3

In a large pot, bring enough water that will cover the sweet potatoes to a boil.

Step 4

Blanch the sweet potatoes by placing the slices in the boiling water for 4 to 6 minutes.

Step 5

Remove the potatoes from the boiling water and drain.

Step 6

Put the slices in a bath of ice water for several minutes until cool.

Step 7

Place the slices in a single layer on the dehydrator tray.

Step 8

Lightly sprinkle cinnamon on the slices if desired.

Step 9

Place the trays in the dehydrator and dehydrate at 90°F for 10 to 12 hours. If your dehydrator does not go as low as 90°F, set it for the lowest temperature.

Step 10

Remove the dried potatoes when the slices are slightly crispy on the outside and slightly chewy in the middle.

Step 11

Place the slices in a single layer in the air fryer basket or tray.

Step 12

Lightly sprinkle cinnamon on the slices if desired.

Step 13

Place the basket in the air fryer set the temperature to 90 degrees.

Step 14

Air fry for about 6 hours. My air fryer was set at 90 degrees and it took 6 hours to dehydrate the slices. Some other brands may take longer.

Step 15

Remove when the slices are slightly crispy on the outside and slightly chewy in the middle.

Step 16

Place the slices in a single layer on a wire rack on top of a baking sheet.

Step 17

Lightly sprinkle cinnamon on the slices if desired.

Step 18

Preheat your oven to its lowest temperature setting.

Step 19

Bake for 4 to 6 hours, or until the dried sweet potatoes are the texture you desire.

Step 20

Depending on your oven, you may find you need less time, or more time. If you find that your oven is naturally hotter, then you may want to leave the oven door slightly open to avoid overcooking them.

Step 21

Allow the treats to cool completely.

Step 22

Store them in an airtight container.
