01 - Remove the steaks from the refrigerator 30 minutes before cooking to let them reach room temperature. Pat dry thoroughly with paper towels to ensure proper searing.
02 - Season both sides of the steaks generously with kosher salt and black pepper, pressing the seasoning into the meat to adhere.
03 - Heat a cast iron skillet over high heat until very hot, approximately 3–5 minutes. The pan should be smoking slightly when ready.
04 - Add olive oil to the skillet, swirling to coat the bottom. Place the steaks in the hot pan and sear without moving for 2–3 minutes until a deep brown crust forms.
05 - Flip the steaks using tongs and immediately add butter, crushed garlic, thyme, and rosemary to the pan.
06 - Tilt the skillet slightly and, using a spoon, continuously baste the steaks with the melted garlic butter for 2–3 minutes, or until desired doneness is reached (125°F for medium-rare).
07 - Transfer steaks to a clean plate and tent loosely with aluminum foil. Let rest for 5 minutes to allow juices to redistribute throughout the meat.
08 - Slice the steaks against the grain and serve immediately, spooning extra garlic butter from the pan over the meat. Sprinkle with flaky sea salt if desired.
