The cooking time for carrots in an air fryer can vary depending on the size and shape of the carrot pieces, as well as the desired level of doneness.   As a general guideline, sliced or diced carrots can be air fried at 200°C or 400°F for about 10-15 minutes, while larger carrot pieces, such as wedges or thick sticks, may require up to 20 minutes.  It's a good idea to check the carrots periodically during cooking and shake the air fryer basket to ensure even cooking. The carrots should be tender and golden brown on the outside when done.
