Marinate the Flank Steak

Start by combining all your marinade ingredients. Turn the steak a few times to ensure that all parts are fully covered with the marinade. You may also place the marinade and the steak into a freezer bag and place it in a bowl. The aim is to simply make sure that the marinade is spread across as evenly as possible.

Put the Grill in Direct Heat

The grill needs to be at medium-high heat before the grilling starts. Just hold your hands above it and if you cannot do it for more than a second or two, the grill is ready.

Gently remove the steak from the marinade and shake off all the excess liquid. Don’t overdo it though. You still need to make sure there’s a coating of the marinade before you start grilling. The marinade prevents sticking to the metal. Gently place the steak on the hot side of the grill. Grill for a minute or two on each side to get a good sear. Move the steak to the cooler parts of the grill and cook for a few extra minutes until the meat is ready.

A long serrated bread knife should work for this.
