Marinated Grilled London Broil

marinated grilled london broil

London Broil is one of our favorite cuts of meat because it is low-fat and easy to toss on the grill. Of course, it can be tough and chewy if you don’t marinate it well, so we always make sure to season it well and marinate it for at least 8 hours — it’s much better if you marinate it overnight.

If you’re one of those super organized people, well, bully for you. Me? I’m just lucky if it’s marinating before lunchtime.

At any rate, this is our new favorite marinade. I found this in an old recipe book; I’m not sure where I found it originally, but I’ve doctored it up so it’s pretty much my own at this point.

The base of the marinade is apple cider vinegar and olive oil. Then you add mayo, worcestershire, thyme, garlic, salt and pepper. The mayo makes it creamy.

Then you just toss it on the grill and cook it till it’s done the way you like it! Personally, I’m not a fan of meat that’s still bleeding, but you don’t want to overcook your London Broil either, so I try to get it till it’s just pink. Like this!

  1. Looks Yummy never thought of adding Mayo cant wait to try it .. I love london broil it reminds me of my childhood my mom always make it, then slice thin.. yummy. I do a similar marinade but add Orange Juice to make it “sweet meat” as my kids call it.

  2. I just brought london broil home today 🙂 and…. thats just about the same marinade I use 🙂 Good minds think alike!

  3. I wanted to try a different marinade. I usually purchase a Tri-Tip when we have red meat for dinner, but with the high prices of beef right now I decided to buy a London Broil which was much more affordable and low in fat. I used your marinade, but I pounded the steak and seasoned it first, then I let it sit in your recipe. It gave it a nice flavor, my husband was upset I threw the leftover marinade away. I think next time I’m going to put my own spin on it, and replace the thyme with tarragon instead. The recipe was easy to make, and my family liked it. On a scale of 1-5 with 1 being the lowest, and 5 being the highest score, I’d give it a 4.50! Thanks for sharing.
