Should flank steak be marinated?
Flank steak benefits from a marinade because it’s not as tender of a cut.The marinade helps tenderize the steak and adds a ton of flavor. Ideally, flank steak should be marinated for 6-24 hours! It makes this recipe a great one to prep the day before grilling.
Pro tip: Allow ¼ to ½ cup of marinade for every pound of beef, and always marinate beef in the refrigerator, never at room temperature.

Why we love beef in our diet:
Beef is packed with essential nutrients and contains 10 essential nutrients, including B-vitamins and zinc, which give you energy and support a healthy immune system. We recently gave our 7 month old steak and she loved it!
There are 17,000 beef farms in Ohio (where we live!) and 98 percent are family-owned and operated. We love knowing where our food comes from.
How should flank steak be cooked?
Flank steak can be pretty tough if it isn’t properly cooked. Grilling it is a great option because it can be cooked at a high heat for short amount of time. The goal is to keep the cook-time to a minimum for a tender steak.
How long does it take to grill a flank steak?
It takes about 10 minutes to cook a flank steak to medium-rare. You will sear it on both sides for 3-4 minutes then finish it on indirect heat for another 6 minutes, flipping halfway through.
Do you close the grill when cooking steak?
Leaving the grill up slows the cooking process because it reduces the heat. Large steaks, like flank steak, are thicker and have much more meat to cook through, so closing the lid allows the heat to penetrate the steak and cook it quicker for a more tender steak.
How to make grilled flank steak:
Marinate the flank steak for at least 6 hours in the refrigerator prior to grilling. Once it’s ready, preheat the grill to high (about 450°F).
Place the flank steak on the grill and discard the marinade. Sear the steak for 1-2 minutes on each side with the grill open then transfer it to indirect heat.
Close the lid and cook the steak for an additional 6 minutes, flipping halfway through or until the steak reaches your desired doneness. It should reach 130-135°F for medium rare.
Remove from the grill and allow to rest for 5 minutes then cut the grilled flank steak across the grain.
