01 - Pat steaks thoroughly dry with paper towels. Brush both sides evenly with olive oil.
02 - Combine salt, pepper, garlic, and rosemary in a small bowl. Rub mixture generously over all surfaces of the steaks.
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 doneness. Adjust timing for preferred doneness: 130°F for medium-rare, 140°F for medium.
05 - During the final minute of grilling, top each steak with 1/2 tbsp butter for added richness.
06 - Remove steaks from grill. Tent loosely with foil and let rest for 5 minutes to allow juices to redistribute.
