Prep the carrots by washing them thoroughly and patting dry. Trim the ends and cut into even sticks about 3-4 inches long and 1/2 inch thick. Consistent sizing ensures they cook evenly.
Place carrots in a mixing bowl and drizzle with olive oil. Toss until each piece is coated completely – this is crucial for achieving maximum crispiness.
Add the seasonings – garlic powder, dried thyme, salt, and pepper. If using honey or maple syrup, add it now. Mix thoroughly to ensure even distribution of flavors.
Preheat your air fryer to 380°F (190°C) for 2-3 minutes. Preheating helps achieve better crispiness from the start.
Arrange the carrots in a single layer in your air fryer basket. Avoid overcrowding – work in batches if necessary for optimal air circulation and crispiness.
Cook for 12-15 minutes, pausing to shake the basket halfway through cooking. The carrots should develop visible caramelized spots and be easily pierced with a fork.
Check for doneness at the 12-minute mark. If you prefer them softer, add 2-3 more minutes. For extra crispiness, increase temperature to 400°F for the final 2 minutes.
Transfer to a serving dish, garnish with fresh parsley if desired, and serve immediately while still hot and crispy.
