Step 1

Whisk together all of the ingredients together in a bowl until combined. Pour the marinade into a resealable freezer bag and add in the flank steak. Seal the bag pressing out the air as you do. Let the steak marinate for at least 4 hours, overnight is best.

Step 2

Preheat your grill to high heat, or about 450° F. Remove the flank steak from the marinade letting the excess marinade drip off. Season the steak on both sides with kosher or sea salt and then place it on clean, oiled, hot grill grates.

Step 3

Grill for 5-6 minutes and then flip the steak over and grill another 5-6 minutes or until the internal temperature reaches 135°F. (medium-rare).

Step 4

Let the steak rest for 5-10 minutes before thinly slicing it. Be sure to slice against the grain.
