01 - Pat steaks thoroughly dry with paper towels. Brush both sides generously with olive oil.
02 - Combine salt, pepper, minced garlic, and rosemary in a small bowl. Rub mixture evenly over all surfaces of the steaks, pressing gently to adhere.
03 - Heat gas or charcoal grill to high temperature, reaching 450–500°F.
04 - Place steaks on hot grill. Cook 4–5 minutes per side for medium-rare. Adjust timing based on preference: 130°F for medium-rare, 140°F for medium. Use instant-read thermometer for accuracy.
05 - During the final minute of grilling, place ½ tbsp butter atop each steak, allowing it to melt and baste the meat.
06 - Transfer steaks to a cutting board. Tent loosely with foil and allow to rest for 5 minutes, ensuring juices redistribute throughout the meat.
07 - Serve steaks immediately with lemon wedges on the side, if desired.
