Salt T-bone steaks generously with salt. Allow steaks to sit at room temperature for 45 minutes before grilling.
Preheat one area of the grill to high heat and the other to low heat.
Brush olive oil on steak and season with garlic and your desired amount of salt and 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.
Move steaks to the low-heat area of the grill for another 5-10 minutes, depending on your desired level of doneness. Check the internal temperature with a digital meat thermometer and pull the steaks at 120-125 degrees for medium-rare.
Rest at room temperature on a foil-tented plate for 5-10 minutes before serving.
