Remove the steaks from the fridge and place on a wire rack on top of a plate/cookie sheet OR on a paper towel-lined plate.

Generously sprinkle kosher salt all over the steaks and let stand at room temperature for about 30-60 minutes, or until at room temperature. Take a paper towel and dry the moisture off the steaks so they are very dry.

Preheat the air fryer to 400º.

Spray or brush each steak with oil, then sprinkle with pepper.

Place the steaks into the preheated air fryer basket, then cook for 10-12 minutes, flipping halfway through cooking. Cook until the internal temperature reaches your desired cook. Check out this temperature table for the cook on your meat—I prefer a medium (140–145º F) or medium well steak (150–155º F).

Remove the steak from the air fryer and place 1/2 tablespoon of butter on each steak. Cover lightly with foil and let it rest for 5-9 minutes.

If slicing the steak, cut against the grain (the direction of the muscle strands are running) and serve.
