01 - Pat the steaks thoroughly dry with paper towels, then brush both sides evenly with olive oil.
02 - In a small bowl, mix kosher salt, black pepper, minced garlic, and dried rosemary. Rub the mixture thoroughly on all surfaces of the steaks.
03 - Preheat a gas or charcoal grill to high heat, targeting 450–500°F.
04 - Place steaks on the hot grill and cook for 4 to 5 minutes per side for medium-rare. Adjust cooking time for desired doneness, using an instant-read thermometer (130°F for medium-rare, 140°F for medium).
05 - Optional: During the final minute of grilling, place 1/2 tablespoon unsalted butter over each steak, allowing it to melt.
06 - Remove the steaks from the grill, tent loosely with foil, and let rest for 5 minutes to preserve juices.
07 - Serve the steaks hot, accompanied by lemon wedges if desired.
