Step 1

Toss the sweet potatoes with the oil, 1/2 teaspoon salt and a few grinds of pepper in a medium bowl until evenly coated.

Step 2

Place the potatoes in the basket of a 6-quart air fryer. Cook at 400 degrees F until crispy on the outside and tender on the inside, flipping halfway through, 35 to 40 minutes.

Step 3

Cut lengthwise along the top of each potato, being careful of the hot steam, then fluff the inside with a fork and season with a pinch of salt. Top with a pat of butter and chopped fresh chives.
