01 - Remove steaks from refrigerator 30 minutes before cooking to reach room temperature. Pat dry thoroughly with paper towels.
02 - Season both sides of each steak generously with kosher salt and freshly ground black pepper.
03 - Heat a large cast-iron skillet over high heat until very hot. Add oil and swirl to coat the pan evenly.
04 - Place steaks in the skillet and sear without moving for 2-3 minutes until a deep golden crust forms.
05 - Flip steaks and add butter, smashed garlic, thyme, and rosemary to the pan.
06 - Tilt the skillet and baste the steaks with melted butter and aromatics for 2-3 minutes, or until desired doneness (125°F for rare, 135°F for medium-rare, 145°F for medium).
07 - Transfer steaks to a cutting board and let rest for 5 minutes before slicing and serving.
