01 - Pat steaks thoroughly dry with paper towels. Brush both sides generously with olive oil.
02 - Combine kosher salt, black pepper, minced garlic, and dried rosemary in a small bowl. Rub mixture evenly over all surfaces of the steaks.
03 - Heat gas or charcoal grill to high temperature, reaching 450-500°F.
04 - Place seasoned steaks directly onto hot grill. Cook 4-5 minutes per side for medium-rare. Adjust timing according to preference: 130°F for medium-rare, 140°F for medium.
05 - During the final minute of grilling, top each steak with 1/2 tablespoon unsalted butter, allowing it to melt and baste the meat.
06 - Remove steaks from grill. Loosely tent with aluminum foil and let rest for 5 minutes to allow juices to redistribute throughout the meat.
07 - Serve immediately with lemon wedges on the side.
