Have you ever had a marinade in mind, but were short just one ingredient? Like the ginger root that’s shriveled in your vegetable drawer? The green onions that were on your shopping list but you forgot to purchase? That’s why I am a huge fan of this Easy Grilled Flank Steak Recipe.

I’m never without one of the essential components of this recipe, so as long as there’s a flank steak in my fridge or freezer, this dinner will happen! Soy sauce? Check. Red wine vinegar, ground ginger, fresh garlic, and vegetable oil? More checks. And it’s one of the best ways to enjoy a flank steak—I guarantee!

It was time for Nick to head back for his senior year of college. For his last dinner at home, I prepared “steak.” He became a beef lover as a tot, and  I always lumped flank steak in with filet mignon, strip steaks, and ribeyes when discussing our entree.

It was another steak–and he enjoyed it as much as those latter options as long as it was cooked rare. Or just short of mooing as Bill would phrase it.

I picked up a Certified Angus Beef® flank steak at our local Market District. I usually save the pricier cuts for when the whole family is gathered, so I went back to this old favorite flank steak marinade recipe, roasted some asparagus and potatoes for a simple, yet fabulous meal. I hope you’ll give this Easy Grilled Flank Steak recipe a shot before the grilling season is over!

Tips for Grilling Flank Steak

Once I started grilling flank steak for the family, it became a regular on our menu rotation. I varied the marinades, but otherwise used the same technique for cooking. Here are a few pointers if you’re new to grilling this cut of meat.

  • Before you marinate your flank steak, “score” or carefully cut into the meat against the grain (perpendicular to the lines you see running across the meat).  I make shallow cuts about an inch and a half apart from one short side to the other, on a slight diagonal. Or you can have your butcher score your beef for you.
  • Besides helping prevent the beef from curling while on the BBQ, scoring also helps the marinade permeate the beef.
  • Beef can take a longer marinating time than chicken or seafood. Marinate overnight or place the flank steak in the marinade early in the day you’re planning to grill for the best results.
  • I like to marinate in a Ziploc bag to avoid spilling marinade into the fridge. Been there, done that! It also makes it super easy to flip the bag a few times throughout the day for even marinade distribution.
  • Flank steak is best grilled to medium-rare. If it’s overcooked, it could be tough and/or chewy. My family prefers rare, but I prefer it a little more done.
  • Slice the meat thinly across the grain. This makes for tender slices.

An easy, flavorful marinade for your flank or tri-tip. Adapted from my friend, Becky.

Prep Time 10 minutes
Cook Time 10 minutes
Total Time 20 minutes
Yield 4 servings


  • 1/3 cup soy sauce
  • 2 tablespoons brown sugar
  • 1 tablespoon red wine vinegar
  • 1/2 teaspoon ground ginger
  • 1 clove garlic, minced
  • 2 tablespoons vegetable oil
  • 1 Certified Angus Beef® flank steak, scored if desired (cut very shallow slits perpendicular to the grain the whole length of the steak, flip and repeat. This helps the marinade permeate the meat).


  1. Score both sides of your flank steak by making shallow diagonal slashes over surface. This will allow the marinade to penetrate a little deeper.
  2. Combine all marinade ingredients in a large ziplock bag. Add flank steak, seal and chill for 6-8 hours (turning occasionally) or overnight.
  3. Bring to room temp before grilling to desired doneness.


Total time does not include marinating time.

  1. Ooh this steak looks delicious. I love the easy marinade. I’ve never actually cooked flank steak. In fact steak, well beef actually is kind of my nemesis. For years AND years I’ve struggled to cook a decent beef roast, although that is now improving. My poor hubby has had to put up with a few well done steaks, he prefers them medium-rare! I’m getting better though. This recipe is a must try, I’m not sure I could achieve rare, medium-rare is more likely! Great post as always. Sammie x

  2. Liz, I LOVE nothing more than some grilled steak. Yours looks delicious! And perfect, as asparagus is in season downunder! xx

  3. Sounds like a great marinade, it truly does use items that are always on hand:@)

  4. Grilling by season is never over unless the Q is covered in shoulder-high snow! Flank steak is one of our favourites, so tender when grilled as perfectly as your was. We just had a Wagu flank at Sopra in Lake Geneva that was excellent.
    I keep ginger in the freezer, no need to peel, just grate using a microplane and you’re good to go. It really is an excellent way to always have fresh ginger around.

  5. I have never had this kind of steak it sure sounds very flavorful!

  6. This steak looks so pretty in pink! Perfectly cooked and love easy and delicious recipes like this one – that marinade sounds great and handy to have these ingredients.

  7. The steak is so perfectly grilled! I am jealous that you can still find green asparagus at this time of year.

  8. What a nice juicy steak!

  9. Senior year is something to celebrate! Hope he has a fantastic one! (I freeze my ginger root and it is always ready to go and keeps virtually forever—or until I use it all!)

  10. We grill flank steak often and I must try your marinade next time – so easy and it sounds so flavorful!

  11. Looks like an amazing dinner! I know my hubby will love this. 🙂

  12. Good luck to Nick! Your steak looks great, and I always have those ingredients on hand too.

  13. Lizzy,
    I haven’t had flank steak in eons. Your recipe looks delicious.

  14. Grilling season is in full steam down here and I’d love one of these steaks but with just a tad less moo. My father-in-law eats his steak blue – too raw for me. I know I’ll like this marinade.
