Step 1

Allow the steak to sit at room temperature for 30 minutes before cooking.

Step 2

Preheat a 3.5-quart air fryer to 400 degrees F. Season the steak on both sides with a generous pinch of salt and several grinds of black pepper. Place the steak in the center of the air fryer basket and cook until desired doneness, about 10 minutes for medium-rare, 12 minutes for medium and 14 minutes for medium-well. Transfer the steak to a cutting board and allow to rest, about 10 minutes.

Step 3

Meanwhile, mash together the butter, parsley, chives, garlic and crushed red pepper in a small bowl until combined. Slice the steak against the grain into 1/4-inch-thick pieces. Top with the garlic-herb butter.
