Slice or prepare the carrots if not already sliced.
Place the carrots in a bowl.
Add the oil, apple cider, and brown sugar.
Make sure it fully coats the carrots and let this sit and soak for about an hour.
If you do not want to do this soak, just coat the carrots with the cooking oil spray and garlic salt and cook. The soak though really does bring out an amazing flavor in the carrots.
Drain the liquid from the carrots and add the carrots to the basket of the air fryer.
Cook at 390*F for about 20 minutes, stirring or mixing after about 10 minutes.
Carefully remove and serve.
Notes
Due to all air fryers heating differently, start checking in around 15 minutes and if not soft enough to your liking, add an additional 5 minutes. These will come out as a roasted taste and texture.
