Marinated Grilled Flank Steaks
These grilled flank steaks were marinated overnight and are almost so tender you can cut it with a fork. The secret is in the special marinade. If you throw on a few sliced onions and peppers on the grill at the same time, you can have dinner ready in a jiffy. Our grilled flank steaks are delicious on our Seared Steak Salad with Strawberry Cucumber Dressing or a Thai Beef Salad. Maybe, Dad would just like a plain steak with a baked potato on the side. The choice is yours.
How to make flank steaks tender
The Flank steak is a cut of beef taken from the abdominal muscles or lower chest of the steer. This steak comes from the well-exercised part of the cow and it can be tough. Who knows why this part of the cow gets so much exercise maybe they do sit ups and crunches? (smiling) Therefore, there are a few things that need to be done to keep this cut of meat tender and delicious.
- Remove any tough fascia from the flank steak before marinating.
- Marinate your flank steak in the refrigerator. The longer you marinate it the better. We like to marinate our steaks the night before so that they have about 24 hours to do their thing. However, you can also marinate them for just 2 hours, but they are not as tender as when you do it overnight.
- Be sure to take your flank steaks out of the refrigerator at least 20 - 30 minutes before grilling to allow the steaks to come to room temperature. Don’t be putting a cold steak on a hot grill! If you put a cold steak on a hot grill they want to shrivel, and it won’t cook evenly. The goal is to cook your steaks quickly over a higher heat to get a nice sear and keep them tender and let them cook evenly.
- Do not overcook the steaks. Cook to a medium rare. Do not cut your steak until after it is cooked.
- Let your flank steak rest for about 10 minutes under aluminum foil before carving and slice very thin. This helps keep the juices in your steak.
- Make sure you cut against the grain of the steak and not with the grain of the steak.
The secret marinade
Just a handful of pantry ingredients make this marinade extra special. Ok, the secret is out! This marinade is fantastic for meat but is also fantastic for mushrooms and grilled veggies too. Just to note, vegetables and mushrooms only need to be marinated for about 15 minutes unlike a steak that needs at least 2 hours or up to 24 hours. For about a 1.5 pound flank steak we marinate our flank steaks with the following ingredients…
- Olive oil
- Soy sauce or Tamari sauce for gluten-free
- Aged balsamico from Mie Radici – it is naturally sweet from the aging process so there is no need to add a sweetener to this recipe as some do.
- Fresh garlic
- Fresh minced onion
- Italian dried herbs
- Fresh ground pepper
How long to cook a flank steak?
That depends on how you like your steaks. If you want to keep your flank steaks tender, be sure to keep them to no more than medium for the best outcome and the most tender steak. You can check the doneness of your flank steak by internal temperature or the finger touch method. Don’t be cutting into your steak to take a look or you will lose all that delicious juice.
- Rare: 125 to 130 degrees F (51 - 54 degrees C)
- Medium rare: 130 to 140 degrees F (54 – 60 degrees C)- our favorite way to grill flank steaks!
- Medium: 140 to 150 degrees F (60 - 65 degrees C)

- Well- not recommended
Finger touch method
The finger touch method is great, especially if you do not own a meat thermometer. Check out this helpful infographic from the Furious Grill.

How long does it take to grill flank steaks to medium rare?
As for a time estimate, we cooked our 1.5 pound (680 grams) for about 4-5 minutes on each side. However, everyone’s heat level can be different depending on if you have a gas grill or coals, etc. So, it is best to go by internal temperature or finger test for best results. Maybe some guys out there will say, by the time I’m finish my first cold beer, their steak is ready… (smiling) It is not an exact science, but hey whatever works for you.

We used to eat a lot of flank steak until I gave up beef. This looks fabulous and I think Father's Day would be a perfect time to serve this to Manservant. He really misses his beef. Your posts are always so informational. Love the finger temperature test! Take care.
Thanks so much Abbe! Time is flying and Father's Day will be here before you know it. Stay well and take care
