Begin by washing and peeling the sweet potatoes. Using a mandoline, slice them thinly to ensure even cooking, aiming for about 1/8 inch thick.

In a mixing bowl, toss the sweet potato slices with extra virgin olive oil, just enough to coat each slice evenly.

In a separate small bowl, combine organic brown sugar, chili powder, ground cumin, and salt. Stir until well blended.

If sweet potato slices released moisture, drain it off before seasoning. Sprinkle the spice mix over the slices while tossing gently.

Preheat your air fryer to 180°C (356°F). Arrange the seasoned sweet potato slices in a single layer in the air fryer basket.

Cook the sweet potato slices for 6-9 minutes, checking halfway for even cooking. Watch for a golden brown color.

Once golden brown, remove chips and transfer them to a cooling rack to enhance crispiness.
