London Broil Recipe

June 3, 2011

London broil is one of most confusing names in the world of meat.  First of all, London broil means nothing in London (kind of like asking for French Fries in France).  London broil refers more to a cooking method than an actual cut of meat.  As far as I can tell the "broil" refers to the fact that it should be seared and cooked quickly over high heat, but I have no idea where the "London" part came from.  More accurately, London Broil is the same cut of meat (though sometimes thicker) as the flank steak.  Increasingly, top round steaks are starting to be labeled more and more as "London Broil".  Whatever the origins, it is a very lean cut of meat with very tough strands of muscle running the length of the steak.  Just the same as flank steak, we are talking about a steak that really benefits from marinades and we need to cook it no more than medium-rare and slice it thin, against the grain, for maximum tenderness.  So you should definitely factor in marinating London broil to your prep time to give the marinade a chance to help break down that tough tissue.  Which brings us to this week's recipe for a very easy and tasty London broil marinade!  The soy sauce will help break down and tenderize the London broil in as little as 4 hours.  If you have time though, overnight is even better.  Let's make a nice little bath for that steak!

  • Prep: 15 mins
  • Cook: 10 mins
  • Yields: 2 to 3 servings


1 London Broil steak

1/2 cup Soy sauce

3 cloves garlic, smashed

2 tablespoons fresh ginger, minced

1/4 cup brown sugar


1Combine the marinade ingredients in a glass bowl and whisk together to combine thoroughly.

2Place the London broil steak in a large, re-sealable bag.

3Pour in the marinade and seal the bag, squeezing out as much air as possible and then place the bag in a refrigerator for 4 - 6 hours or overnight.  Turn the bag at least once during that time to make sure all of the sides of the steak get some soy lovin'.

4Light your grill to high heat.  We are going to cook this now-somewhat-leaner tough hunk of meat quickly over high, direct heat until around medium-rare.  Remember, the longer you cook an already tough cut of meat, the tougher it will be.  I recommend to err on the side of rare because you can always stick it back on for a few minutes if you really feel the need.  Once it is over-cooked though, you might as well call up the pizza guy while the kids fling around your new leather frisbee in the backyard.

5Remove the marinated London broil from the bag and place on the hottest part of the grill.

6Grill with the lid open 5 - 7 minutes per side (we always rotate half way through to get those nice looking grill marks, right?).

7Once it has grilled for a total of 10 - 14 minutes, remove the grilled London broil from the grill and place on a cutting board and allow to rest for about 5 minutes.

8Now here is the other key to getting the maximum tenderness out of this cut of meat.  Using a sharp knife, slice the meat thin against the grain.  For more detailed directions on how to do that, check out these instructions, but here are the Cliff notes.  The grain on the London broil should be obvious once you pick it up on one side with some tongs and bend the meat.  Find the direction of the grain (9 times out of 10, the grain runs the long length of the cut) and then start slicing thin, perpendicular to the grain like so:

Cooked up a 2.2 lb London Broil last night. Looked great after grilling, rest for 10 minutes and the taste was great. I let it marinate 2 days, didn’t mean to, just happened that way. 140 degree meat temp was a perfect medium. I like my meat medium rare but my wife likes it medium, so medium it was. I will cooking this more and more.

I grilled a 2.2 lb London broil last night and it was great. Medium was at 140 degrees. I like medium rare but my wife likes medium, so medium it is. Looked great after grilling, let it rest 10 mins and it tasted great. Was a very good meal last night. I let it marinate 2 days before cooking it. Hadn’t planned on 2 days it just worked out that way … Very tasty

I use this method ALL the time & my steaks turn out perfect every time! I have a different marinade but the trick about cooking on high heat and cutting against the grain has made London broil my kids’ favorite meal. My only problem comes with really huge cuts of meat – 7 minutes leaves it too rare for my kiddos (I love it, but they prefer it less blue).

We cooked this last night. The trick is to follow the instructions on cutting the steak.
