Step 1

Using a mandoline, slice the beets very thinly, about 1/16 inch (2 mm) thick. Line a baking sheet with paper towels and arrange the beet slices on the towels in a single layer. Top with another layer of paper towels and press down firmly. Set aside for 10 minutes to allow the beets to dry.

Step 2

In a large bowl, toss the beet slices with the olive oil and a generous pinch each of salt and pepper.

Step 3

Preheat a Philips air fryer to 300°F (149°C). Spray the air fryer basket with nonstick cooking spray, then arrange half of the beets in the basket in a single layer. Insert into the air fryer and cook until the beets are crisp and browned at the edges, 12 to 15 minutes. Transfer the beet chips to a platter and repeat to air fry the remaining beets. Serve immediately. Serves 2 to 4.
