Season your steak. To do this, simply rub olive oil on both sides of the steak and then sprinkle salt and pepper on top.
Once the air fryer is preheated, place the steak inside and cook for 6 minutes and flip it.
The time to cook it will depend on the size of the steak. Use a thermometer to check the temp. Once the steak reaches the appropriate temperature for the doneness (see chart above) you want, remove the steak. Let rest for 5 minutes before slicing.
