Combine all marinade ingredients in a medium bowl. Whisk together until fully combined (oil and other ingredients will separate; this is normal)
Place steaks into a food storage bag. Pour marinade over them, ensuring that each steak is immersed in the liquid. Seal the bag and lay it flat in the refrigerator. Marinate for a minimum of one hour, up to 24 hours
Remove steaks from the refrigerator. Drain the marinade from the bag. Rest steaks at room temperature for 45 minutes
Preheat the grill to 450-500 degrees. Pat steaks completely dry. Add salt and pepper to both sides of each ribeye
Grill the steaks for 3-5 minutes on each side until seared. Then, move them to a low-heat area of the grill to continue cooking for another 8-12 minutes for medium rare
Transfer steaks from the heat to a plate tented with foil to rest for 5-10 minutes before serving
