Salt T-bone steaks generously with salt on both sides and allow to sit at room temperature for 45 minutes before grilling. About 10-15 minutes before grilling, brush the grill grates with olive oil and preheat one area of the grill to high heat and the other to low heat
Season steak with a sprinkle of salt, if desired, and black pepper. Place steaks on the high-heat area of the grill for 3-4 minutes. Flip to the other side with tongs and sear for another 3-4 minutes
If more time is needed for the steak to reach your ideal doneness level, move them to the low-heat area of the grill and close the lid to cook for another 2-10 minutes. Use your meat thermometer to check the thickest part of the steak
Rest at room temperature on a foil-tented plate for 5-10 minutes before serving
