Pat steaks dry with paper towels for a better sear.
Brush both sides and edges of steaks with olive oil.
Season steaks generously on all sides with salt, pepper, and garlic powder.
Allow steaks to come to room temperature for 30 minutes before grilling.
Prepare charcoal grill by lighting coals until ash-gray and arrange for two heat zones (direct high heat and indirect cooler side).
Clean grill grates with brush and oil before grilling.
Alternatively, preheat gas grill with all burners on high for 10–15 minutes, then turn off one side to create two heat zones.
Place steaks on direct heat side and sear with lid open for 2–3 minutes per side without moving them.
Move steaks to indirect heat side, close the lid, and continue cooking to desired doneness using a meat thermometer.
Remove steaks from grill when 5°F below target temperature due to carryover cooking.
Rest steaks loosely covered with foil for 10 minutes before slicing against the grain.
Serve whole or sliced with your preferred side dishes.
