This is, hands-down, the best homemade flank steak marinade made with olive oil, lime juice, soy sauce, garlic, and seasonings. Makes just under 2 cups, enough for one large flank steak.
My mother-in-law gave us this marinade years ago that she used for London Broil and I swear it’s the best flank steak marinade that I’ve ever tried! I’ve experimented with so many variations and always seem to come back to this simple recipe. *I am a compensated member of the 2016 Beef Expert Bureau. I love and enjoy lean beef as part of my fit and active lifestyle. As always, all opinions are my own.
What Is MSG and Is It Bad For You?
The original recipe contains 1/2 tsp Accent seasoning, which I used to avoid since it contains MSG. However, after learning from a few of my friends that are registered dietitians that MSG is not so bad after all, I’ve started including it again in some of my recipes. There is a great article in Men’s Health from my friend, Chris Mohr Ph.D., RD, that explains why MSG doesn’t deserve the bad rap that it’s been given. It’s a wonderful concentrated form of Umami that gives food incredible flavor.
Of course, always decide for yourself if it’s an ingredient that you want to include. It’s always your body, your diet, and your choice, of course. I was on the anti-MSG train for quite some time. If you chose to avoid it, the marinade is still great without it. You can always substitute with an all-purpose seasoning blend. I’ve used Mrs. Dash and FlavorGod’s “Everything” seasoning with good results.
We eat a lot of flank steak in this house. It’s a flavorful lean cut that comes out juicy and tender after marinating. It’s also extremely versatile. Stay tuned for my next post later in the week on how you can batch cook steak for meal prep and enjoy it for breakfast, lunch, and dinner! Batch cooking is one of my eating lean strategies and it also saves a lot of time in the kitchen. That leaves more time for weightlifting and hanging out with my family. 🙂
