This easy recipe, adapted from Cooks Illustrated, is one of my favorite ways to prepare flank steak. You can make the marinade in the morning, let the meat soak up its flavor all day, then come dinnertime all that’s left to do is fire up the grill. Be sure that your grill is very hot so you get nice grill marks, and cook the meat no further than medium-rare; flank steak is a very lean cut, so it can be a bit tough if over-cooked.

Grilled Flank Steak with Garlic & Rosemary

Servings: 4
Total Time: 30 Minutes

Ingredients

  • 1/2 cup extra virgin olive oil
  • 2 tablespoons fresh chopped rosemary
  • 4 cloves garlic, roughly chopped
  • 2 teaspoons kosher salt
  • 1/4 teaspoon freshly ground black pepper
  • 2 - 2-1/2 lb flank steak

Instructions

  1. Make the marinade by combining the olive oil, rosemary, garlic, salt and pepper in a blender. Blitz for a few minutes, until garlic and rosemary are pulverized.
  2. Place the flank steak in a medium baking dish. Using a fork, poke meat about 10 times on each side. Pour the marinade over top and turn the steak a few times to coat evenly. Cover with saran wrap and refrigerate for at least 1 hour or overnight.
  3. Grease grill with oil and preheat to high. When grill is hot, grill flank steak covered for about 5 minutes. Turn and cook covered for about 3-4 minutes more. Let meat rest on cutting board, covered with aluminum foil, for about 15 minutes. Slice very thin against the grain.

    Had this last night with your mashed potatoes. Very very good. Next time I will allow steak to marinate overnight for a more intense flavor

    My daughter loved this steak, she won’t stop raving about it. I loved it too and also the fact that it took me all but 5 minutes to get everything in a zip- loc bag. Since Jen has introduced me to flat-iron steak it’s now my go-to for steak night. this was so tasty and juicy. I served this with Jen’s scrumptious!!!-Curried Roasted Carrots tonight.

    Flank steak is very tricky to make, as the recipe states, if you cook it even slightly longer then you are supposed to, forget it…it is very tough and practically inedible. But done right, it is one of my favorites, so tender and juicy! Because every single recipe I have made from this site has come out perfect (I’m not even exaggerating!) I thought I’ll give this a go too. Flank steak will take to just about any marinade, but I wanted to try the recipe verbatim. It was absolutely amazing; the grilling time is SPOT ON and that’s what I typically struggle with. Five minutes, flip and then four minutes more and rest for 15, it was perfection!
    For those of you who are scared to tackle flank steak, try this recipe, pay close attention to grilling times and be patient, allow it to rest the full 15, it is critical!
    Like a broken record…thank you Jenn for yet another fantastic recipe!

  • Are you guys wiping off the marinade with paper towel before grilling? If not, does the rosemary burn? Thanks!

    • Hi Bob, If you chop it finely, it should be ok.

    This was SO good! I am not a steak lover, but I used this with some flank steak and it was so good.

    My son who is very finicky about his steaks loves this. In Fact he wants to marinate his Rib Eye steaks in this…..normally other than Garlic Powder, salt and pepper….nothing else touches his steaks.

  • I made this for a super bowl party and it was a hit! I love garlic and i added some extra. Make sure to poke a lot of holes in the steak so the marinade can sink in. Such great flavor, can’t wait to make it again!
