Step 1

To a gallon size resealable bag, add all ingredients except the steak. Seal the bag and shake to combine.

Step 2

Add the steak to the bag and seal it. Shake to coat, massaging the marinade into the meat so it is completely coated. Refrigerate 2-24 hours.

Step 3

Preheat an outdoor grill to medium-high heat (about 400-450 degrees F).

Step 4

Remove flank steak from the marinade and transfer to a plate. Discard the marinade. Season both sides of the flank steak with salt and pepper.

Step 5

Cook marinated flank steak on the hot grill for 6-8 minutes per side for medium rare. Rest on a cutting board for 5 minutes. Thinly slice steak against the grain. Serve immediately.
