I recommend selecting a 1" thick steak for this recipe. If you select a thinner steak, then you may need to adjust the time down from the recommended time of 10 minutes to achieve a medium-rare steak. A thicker steak may require you to adjust the time up from 10 minutes for medium-rare. Most importantly, aim to remove your steak from the air fryer when the internal temperature is between 125F and 128F for best results.
