Preheat the air fryer to 385°F if recommended. Scrub, dry and optionally peel the carrots.
Cut into 2-inch batons about 1/2 inch wide, halving or quartering thick sections.
Toss with oil, salt and pepper. Arrange in a mostly single layer.
Air fry for 8 minutes. Shake, then cook 4 to 7 minutes more until the widest piece is almost tender.
Whisk melted butter, honey and garlic powder. Toss the hot carrots with a thin coating, leaving excess glaze in the bowl.
Return to the basket at 360°F for 2 to 4 minutes, shaking once, until glazed and easily pierced.
Transfer from the hot basket, toss with lemon juice and parsley, and serve.
