Preheat the air fryer: Set your air fryer to 380°F (193°C) for 5 minutes.
A hot basket helps the carrots brown faster.
Prep the carrots: If using whole carrots, peel and slice into even sticks or coins about 1/2 inch thick. Uniform size means even cooking.
Make the glaze: In a bowl, whisk together olive oil, honey, balsamic vinegar, salt, pepper, and garlic powder. Add red pepper flakes if you like a little heat.
Toss to coat: Add the carrots to the bowl and toss until every piece is well coated. Don’t skip this—coverage is key for flavor and caramelization.
Arrange in the basket: Place the carrots in a single layer in the air fryer basket. A bit of overlap is fine, but avoid piling them too high.
Air fry and shake: Cook at 380°F (193°C) for 10–14 minutes, shaking the basket halfway through.
Start checking at the 10-minute mark. They’re done when tender with browned edges.
Finish and taste: Transfer to a bowl. If using, stir in a teaspoon of butter for extra gloss.
Adjust salt and pepper, then top with fresh herbs.
Serve: Plate immediately for the best texture. These are great hot, but also taste lovely at room temp.
