Preheat air fryer to 400°F for 1 minute.

Pat steak dry with paper towels and season both sides with salt, garlic powder, onion powder, and pepper.

Place steaks in the air fryer basket and cook 7-10 minutes for medium-rare (12 minutes for medium), flipping halfway through.

Remove steaks to a cutting board and allow to rest for 5-10 minutes before slicing.

Top with butter, slice, and garnish with fresh herbs if desired.
