Whisk together marinade ingredients. Pour into zip-top bag containing steaks. Seal tightly and flip a few times to evenly distribute marinade. Set in refrigerator to marinate for 30 minutes-2 hours, flipping bag occasionally.
Preheat gas or charcoal grill to 400°F.
Remove steaks and discard marinade. Season with salt and more pepper to taste.
Place steaks on oiled grates and grill for approximately 7-9 minutes on one side, or until moisture starts to pool on the top and beef releases easily from grates with tongs. Flip once, grilling on the other side for 6-8 minutes or until internal temperature reaches 135°F with meat thermometer inserted into the thickest part of steak.
Transfer steaks to platter and let rest for 5-10 minutes before slicing against the grain.
