Making a flank steak is one of the easiest and most delicious things you can do in your kitchen. This simple recipe only takes a few minutes to put together.

The marinade breaks down the muscle fibers and makes is tender and juicy. It’s the perfect cut of meat for grilling. Plus, the leftovers are great cold in sandwiches or salads. Give it a try tonight!

Should you tenderize flank steak before grilling?

We either run a tenderizer over the steak or cross-score the steak before we marinate it. Both the process of either tenderizing or cross-scoring and the ingredients in the marinate break down the muscle that can make a flank steak chewy.

I do the same thing when I’m using a flank steak for fajitas. It gets tenderized and marinaded before it goes on the grill. Flank steak is an excellent cut for fajitas. The tenderizing or cross-scoring help the marinade absorb into the whole steak.


The marinade that I use is completely customizable. You want to have your oil and vinegar as that is the best base but you can add any spice you like with that base. Other things that you could add:

The Marinade Process
  • Soy Sauce or Amino Acids
  • Onion
  • Orange Juice
  • Pineapple Juice
  • Ginger
  • Beer
  • Ketchup
  • Lime Juice

Quite frankly, the options are limitless. You can adapt the recipe to suit your taste. You also don’t have to fuss over exact measurements. If you like a little more heat, add more cayenne. If you love rosemary, you can add that. It’s a great way to experiment with flavors.

Flank steak is a cut of beefsteak taken from the flank, which lies forward of the rear quarter of a cow, behind the plate. French butchers call it bavette, which means “bib”. In Brazil, it is called fraldinha (“little diaper”) and vazio (“empty”) in the Rio Grande do Sul. The cut is common in Columbia, where they call it sobrebarriga (“over the belly”); sobrebarriga a la brasa is a Colombian recipe for braised flank steak. Argentina, Uruguay, and Spain call flank steak vacío (“empty”).

Is a Flank Steak a good cut of Beef?

I remember when flank steak was really cheap because it wasn’t considered a very good cut of beef. That isn’t the case anymore. I paid over $10 per pound for this steak.

It’s a great cut of beef but you need to marinate it (in my opinion) to get it that way

What if You Don’t have a Grill?

We have only made this recipe on the grill but you can certainly put it under a broiler and even use a cast iron skillet or griddle on the stovetop.

Because the steak is thin, you basically just want to get a nice sear on both sides and then cook it to your preferred doneness. We like our steak rare so it doesn’t stay on the grill long after both sides are seared.

Cutting a Flank Steak

This is really the key! You have to cut your flank steak correctly after it comes off the grill. You want to cut against the grain with a very sharp knife in even thin slices.

Hide Nutrition Info
  • 1/2 cup olive oil
  • 3 tbsp red wine vinegar
  • 2 tbsp lemon juice
  • 1 tbsp dijon mustard
  • 1 tbsp Worcestershire sauce
  • 2 tbsp crushed garlic
  • 2 tsp salt
  • 2 tsp pepper
  • 1/4 tsp cayenne pepper
  • 1 tsp thyme
  • 2 lb flank steak

Lay the flank steak out onto the cutting board and run a tenderizer across the steak several times on both sides. Place in a gallon plastic bag
In a large measuring cup combine all the marinade ingredients, and pour over the steak in the bag. Seal the bag, pushing out as much air as possible, and let marinate in the refrigerator for 6-24 hours.
Remove steak from the bag and let any excess marinade drip off. Place on a plate to sit while you prepare the grill.
Place on high heat grill to sear both sides for 2-3 minutes each, then lower heat and cook to desired doneness. We like rare so we cook to 125° internal temp which is about 5 minutes.
Take off the grill and let sit for 5 minutes.
Slice against the grain and then serve
  • Some of our favorite sides are twice-baked potatoes, broasted potatoes, or mashed potatoes with this recipe. We add a veggie or side salad for a meal.

    There is no "correct" way to cut anything, cut it however you like. Unlike shoe leather, cooking steak for 25 minutes is over-cooked.

      I believe the 25 minute "cook time" is a misprint. No steak takes 25 minutes to cook. And perhaps she should have said that it is the recommended way to cut a flank steak for the best result.
