Prepare a grill or grill pan for medium-high heat cooking.
Season steaks with salt and pepper on both sides.
Place steaks on the grill and cook 3 minutes; rotate each steak about 90 degrees (this will give you nice grill marks) and cook 3 more minutes.
Flip steaks and repeat grilling and rotating process, cooking until steaks reach desired doneness, about 5 minutes more for medium-rare (145°F internal temperature).
Transfer steaks to a cutting board, rub with garlic, drizzle with oil and let rest 5 minutes.
