Flank steak, once a low-budget cut of meat has become trendy and popular once again. When marinated and grilled, this steak is tender and flavorful. This flank steak marinade is mildly spicy and perfect for flank steak fajitas. I serve the steak grilled medium-rare, sliced thin with sautéed onions, red bell peppers, guacamole, cheddar cheese and tortillas. It’s one of my favorite dinners. Left-overs are also delicious mixed in with a healthy green salad tossed in a red wine vinaigrette.

Flank steak can be a bit of of a tough cut of meat. This is why it benefits from being immersed in a flavorful marinade. It also helps to know a few other tips for cooking and serving the steak.

Where does flank steak come from?

Flank steak is a relatively long cut of beef from the lower chest area of the cow.

How long do you grill flank steak for?

How long you grill the steak depends a little on how thick it is. It doesn’t take long to achieve that perfect medium-rare grill. Generally, not more than about 5 minutes per side.

How do you slice flank steak?

Before you slice, allow the steak to rest a few minutes. This allows the muscles to relax and retain the tasty juices. If you cut into the meat right away, the juices and flavor will run out. Slice the meat “against the grain”. Look for the direction the grain (the muscle fibers) is going. Cut against it, not running along with the grain. This allows for shorter cuts of muscle fibers, which in turn means a more tender piece of meat to chew on.

How long should I marinate a flank steak?

This marinade is quite forgiving. So, go ahead…make it the night before, toss the steak in a large zip-lock bag and let it marinate in the refrigerator. When you come home from work, it will be ready to pop onto the grill. You’ll be savoring that beer and flank steak fajitas in no time. Yum!

This marinade is mildly spicy and perfect for flank steak fajitas. Serve the steak grilled medium-rare, sliced thin with sauteed onions, red bell peppers, guacamole, cheddar cheese and tortillas.

  • 1 1/2- 2 lbs flank steak
  • 1 serrano chile (diced)
  • 2 large garlic cloves (minced)
  • 2 tbsp Worcestershire sauce
  • 1/2 cup Tamari or soy sauce
  • juice and zest of one Persian lime ((about 1/2 cup))
  • 1 small white onion (sliced)
  • 1/4 cup extra virgin olive oil
  • 1 handful cilantro (chopped)
  • 1 tsp cumin
  1. Whisk together all the ingredients. Immerse and cover the steak with the marinade in a large resealable zip lock bag or lay it flat in a baking dish. Marinate the meat 4-6 hours in the refrigerator, turning occasionally or overnight until you are ready to grill.

Slice the cooked flank steak across the grain. This means cutting across the fibers rather than along with the grain of the meat.

If you are gluten-free use Tamari instead of soy sauce.

    I don’t eat steak but my husband loves steak. This recipe will be saved for him. I was wondering if I can serve some spicy relish on the steak?

      Thanks for visiting Aish. I’d say yes, serve up some spicy relish on the side. That sounds great. I love this for steak fajitas. So, I often add a medium-spicy salsa with it. The marinade is not overly spicy because my kids won’t eat it if it’s too spicy. You can always add more spice later in my humble opinion.

       
  3. Oh my goodness this looks good! There’s nothing in that marinade that I don’t love!

     
  4. Yummy. I love flank steak. I really wish I had a grill. I usually do my meat recipes in the oven, so I’ll have to modify that part. But I can’t wait to make this. It looks absolutely fabulous!

     
  5. I love flank steak! But you are right, it really needs to be marinated to be tender! I love this marinade! Cumin is one of my favorite things in the world!

     
  6. i did not grow up eating beef but now i do love a good steak..your flank steak sounds like a wonderful recipe.

     
  7. Such awesome tips when dealing with a piece of meat like a flank steak that can be tough to eat. Yours look so juicy and tender thanks to that beautiful marinade!

     
  8. You’re giving me the motivation to try flank steak again. I like it, but it can be so tough and I haven’t been able to crack that code.

     
  9. I”m always half amused, half annoyed when the cheap cuts go trendy (and more expensive!) They usually have so much flavor, though… you just have to know how to cook them!

    And this marinade sounds delicious.

     
  10. This looks and sounds delish! Have you ever tried using Flat Iron Steak instead of Flank? I find it to be much more tender and not as chewy!

     
    • Michelle Barsness

      Hi Amanda, Yes, flat iron or skirt steak works too. Choose whichever cut you can find. I find they are not always available.

       
  11. Flank steak is one of our favorite meats to grill! And this marinade sounds fabulous! I love the spice in it, and I know my husband will, too.

     
  12. Great marinade. I like that I have most of the ingredients. Thanks for sharing.
