01 - Remove steaks from refrigerator 30 minutes before cooking. Pat dry thoroughly with paper towels to ensure proper searing.
02 - Generously season both sides of each steak with kosher salt and freshly ground black pepper, pressing seasoning into the meat.
03 - Heat cast iron skillet over high heat until extremely hot, approximately 3–5 minutes. A properly preheated pan is essential for developing a crust.
04 - Add olive oil to skillet, swirling to coat bottom. Place steaks in pan and sear undisturbed for 2–3 minutes until a deep brown crust forms.
05 - Flip steaks and immediately add butter, crushed garlic, thyme, and rosemary to the pan.
06 - Tilt skillet slightly and continuously baste steaks with melted garlic butter using a spoon for 2–3 minutes. Cook until internal temperature reaches 125°F for medium-rare.
07 - Transfer steaks to a plate and tent loosely with foil. Let rest for 5 minutes to allow juices to redistribute throughout the meat.
08 - Slice steak against the grain. Serve with pan juices and garlic butter spooned over the top. Finish with flaky sea salt if desired.
