Marinated Flank Steak


My local grocery store recently had London Broil on sale for buy one get one free. This is a great way to get your meat for half price. So I bought one and I got one, which cost me just under $10. I came home and started looking for what I wanted to make with it. I had a recipe from Kalyn’s Kitchen for Marinated Flank Steak and decided to give it a try.

According to RMK follower Trish who worked in a meat shop, London Broil can be substituted for flank steak but they are not the same cut of meat. London Broil is a thicker cut of top round. Trish said, “flank steak is superior for marinating because the texture provides lots of yummy nooks and crannies for delicious marinades such as this one to really get into the meat. The same is not true for top round (or London Broil) which tends to be drier and tougher than flank steak.”

This was a wonderful marinated and worked fine with my London Broil. We loved it! Enjoy grilling while you still can. Here in Utah we hopefully have a few more weeks of weather that will allow us to still grill outdoors. Tomorrow make sure to stop by for a grilled dessert that involves a fruit that is in season right now!


Marinated Flank Steak
(Makes 4-6 servings)

2-3 pound flank steak or London Broil
2 T balsamic vinegar
2 T fresh lemon juice
1 T Dijon mustard
1 T Worcestershire sauce
1 T finely minced fresh garlic
1/2 tsp. dried oregano
1/2 tsp. dried basil
1/2 tsp. dried thyme
1 tsp. smoked paprika or paprika
1/4 cup olive oil

Combine balsamic vinegar, lemon juice, Dijon, Worcestershire sauce, garlic, and spices, then whisk in olive oil.

Trim the flank steak so there is not a lot of visible fat. Then make small scores about 1/4 inch deep and 1/4 inch apart on both sides of the meat. (This allows the marinade to penetrate more, but it’s optional.) Place meat in a ziploc bag, using the smallest size you can fit it into. Pour marinade mixture over meat, then marinate in refrigerator 8-24 hours.

To cook, take meat out of the refrigerator, drain off marinade, and let it come to room temperature while you preheat grill to high heat. (you can rinse the bag in warm water if your in a hurry.) Turn grill to medium-high or let coals cool down before you put the meat on. If using Polder Meat Thermometer, cook to a temperature to 130F. If using instant read meat thermometer, start checking temperature after you turn the meat and cook to 130F. I turned the meat after about 6 minutes, and my flank steak reached this temperature in about 11 minutes, but cooking time will depend on how hot the grill is, the size of your steak, and the temperature of the meat when you start. The meat will continue to cook as it rests, so it’s best to remove from the grill when it’s underdone rather than overdone.

When meat reaches that temperature remove from the grill and let rest 5-10 minutes for smaller pieces or 10-15 minutes for larger pieces. Cut meat into thin slices across the grain and serve immediately.

  • The recipe looks FANTASTIC!
    I do need to respectfully disagree that flank steak and london broil cuts are one in the same. I worked in a meat shop for some time and they are definitely not the same. Even the link that Kalyn provides says that London Broil (Which is a thicker cut of top round) can be used as a *substitute* for flank, which is from a different area of the beef. Search Cook's Thesauraus for both flank and top round to see diagrams of the different parts of the beef they come from. IMO flank steak is superior for marinating because the texture provides lots of yummy nooks and crannies for delicious marinades such as this one to really get into the meat. The same is not true for top round (or London Broil) which tends to be drier and tougher than flank steak.
    I've never seen any meat shop label flank steak as London Broil.
    Flank is one of our favorites to grill so I'm always looking for new marinades. Can't wait to try this one!

  • Wow!! That looks awesome!

  • I love flank steak and this recipe sound so good! I'd better not tell my hubby about it or I'll be running out to buy some steak right now :-)!

  • My husband loves beef, but I only have a few tried and true recipes so it'll be great to try out another. Thanks!

  • So glad you liked it! And what a great photo of the steak. I think meat is so hard to photograph, but you nailed it on this one.

  • Oh my…you really know how to tempt a girl! This looks like an excellent marinade recipe, will add it to my book. We just recently moved to a small town (away from the big city) and there are no Costco's or Sams clubs to buy Flank steak..we are dying!! I'm going to have Flank steak on the brain for the next two weeks..Mmmmm!!!
