01 - Remove steaks from refrigerator 30 minutes before cooking. Pat thoroughly dry 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 a large cast-iron skillet over high heat until very hot. Add oil and swirl to coat the pan bottom evenly.
04 - Place steaks in the hot skillet. Sear without moving for 2-3 minutes until a deep golden-brown crust forms on the first side.
05 - Flip steaks and immediately add butter, smashed garlic cloves, thyme, and rosemary to the pan.
06 - Tilt skillet and spoon melted butter and aromatics over steaks continuously for 2-3 minutes. Cook to desired doneness: 125°F for rare, 135°F for medium-rare, or 145°F for medium.
07 - Transfer steaks to a cutting board and let rest for 5 minutes to allow juices to redistribute. Slice and serve.
