Preheat your grill to high heat (450°F or hotter) for 10 minutes. Mix kosher salt, black pepper, garlic powder, onion powder, paprika, and cayenne in a small bowl to create your seasoning blend. Pat steaks dry with paper towels and brush lightly with olive oil on both sides.
Season each steak generously with your spice mixture, coating all sides evenly. Place steaks on the hottest part of the grill and sear for 4–5 minutes without moving them—resist the urge to flip or adjust, as undisturbed searing creates that beautiful crust.
Flip steaks carefully and sear the other side for another 4–5 minutes until a dark brown crust forms. The juicy grilled steak crowd recipe depends on this initial sear to develop flavor and lock in moisture for maximum tenderness.
Move steaks to a cooler zone of the grill (medium-low heat or the side away from direct flames). Melt butter in a small skillet on the side burner, then add minced garlic, rosemary, and thyme to infuse the butter with aromatic flavor.
Use tongs to position steaks slightly tilted, then spoon the garlic butter over the tops repeatedly for 3–4 minutes, basting continuously. This step adds incredible flavor and ensures even cooking throughout the meat while keeping it incredibly juicy.
Check internal temperature with a meat thermometer: 120–125°F for rare, 130–135°F for medium-rare, and 140–145°F for medium. Remove steaks to a warm plate and rest for 5 minutes uncovered—this allows carryover cooking and gives juices time to settle throughout the meat.
Squeeze fresh lemon juice over each steak just before serving to brighten the rich, savory flavors. Serve immediately while still hot, with any remaining garlic butter drizzled on top for extra decadence.
