Remove steaks from fridge 20 minutes before cooking. Pat completely dry with paper towels. Brush both sides lightly with olive oil. Season generously with salt, black pepper, and garlic powder.

Set air fryer to 400°F (200°C) and preheat for 5 minutes to create the initial sear.
Place steaks in the basket with space between them. Cook for 5 minutes, then flip with tongs. Cook an additional 4-7 minutes depending on preferred doneness (4 min rare, 5-6 min medium-rare, 7 min medium). Check internal temperature at the 8-minute mark and pull steaks at 130°F for medium-rare (the temperature will rise to 135°F while resting).

Transfer steaks to a cutting board and tent loosely with foil. Rest for 5 minutes to allow juices to redistribute and temperature to climb.
Mix softened butter with chopped thyme and rosemary. Place a dollop of herb butter on each steak. Optionally drizzle with balsamic glaze before serving.
