Preheat the air fryer to 390°F. If your air fryer does not have a preheat function, run it empty at 390°F for about 5 minutes.
Wash and peel the carrots. Cut each carrot into thirds, then slice each piece in half lengthwise so the carrots are similar in size for even cooking.
Place the carrots in a large mixing bowl. Add the olive oil, salt, black pepper, and garlic powder. Toss until the carrots are evenly coated.
Arrange the carrots in a single layer in the air fryer basket. Cook in batches if necessary to avoid overcrowding.
Air fry for 20–25 minutes, shaking the basket or tossing the carrots halfway through the cooking time, until the carrots are tender and lightly browned around the edges.
Serve immediately while warm.

Notes
Cutting the carrots into similar-sized pieces helps them cook evenly.
For extra caramelization, cook for an additional 2–3 minutes if desired.
Garnish with chopped fresh parsley or grated Parmesan cheese before serving for extra flavor.
