Cooking steak in the air fryer is a game-changer. Season your favorite cut of steak with salt, pepper, and any other desired spices. Preheat the air fryer to 400°F and cook the steak for 8-10 minutes, flipping halfway through for medium-rare. For a well-done steak, cook for an additional 2-3 minutes. Top the steak with a pat of herb butter and let it melt over the hot meat. Serve with roasted potatoes and a side salad for a satisfying dinner.
