What Is A London Broil?
London broil got its name from not from the cut of meat but the way it is cooked. It originated as best cooked when marinated and broiled. Over the years that has changed and London Broil, is now commonly done on the grill and occasionally in the smoker.
The actual cut of meat is a top round steak or flank steak and is typically known as a tougher cut of meat from the rear of the cow. When at the grocery store you will frequently see it labeled and marketed as a London broil. And it should be noted that the term London broil has nothing to do with London but is a North American creation.
Smoked London Broil Marinade
The key to a good London broil is the marinade. The marinade while adding flavor will also help break down some of those tougher tissues in the top round roast and make it far more tender than it would be otherwise.
Our ingredient list for the marinade is as follows, all the measurements in the recipe card:
- minced garlic
- soy sauce
- Worchester sauce
- lemon juice
- olive oil
- FlatIron Hatch Valley flakes
- red wine vinegar

How To Smoke A London Broil
Now that we have the London broil marinaded. We are going to get it on the smoker. I did this on my Kettle but nothing saying you can’t smoke this London Broil on pellet grill or other smoker of choice. I have also smoked London broil on my WSM. I used B&B lump and ran it at 250° with some pecan wood chips. When smoking London broil, you will only want to take it to medium at most. London broil, If you shoot for to high of an internal temperature you will likely end up with a dried out and chewy cut of beef.
Place the London broil in the smoker and we are going to let it ride until the internal temperature reaches 125°. For a meat thermometer and these one meat smokes, I love using my ThermoPro TP20. What I love about this recipe is we are not having to do anything to the steak while its on the smoker. Only when its time for the reverse sear do we need to do anything. Reaching ort ideal IT will take about an hour, maybe just a little more than that.
When the London broil internal temp reaches 125° we are going to reverse sear it. Depending on how you do this is up to you. I will frequently get it over to my gas grill for the reverse sear. If I were to do this on my Weber Kettle, I might get the coals cranked up and do it that way as well. Even though this one was on my Kettle it was easier to get it on the gas grill. I hit each side with the reverse sear for 3 minutes and then pulled it.
While our initial IT is going to go to a medium rare temperature, the reverse sear and rest and will bring this up to a medium finish. Adjust your timing accordingly if you prefer a different level of doneness.
After the reverse sear, I tented it with aluminum foil and let it rest for about 15 minutes. After the 15 minutes of rest, I sliced it. The best way to slice a London broil is to do so against the grain, giving you the most tender cut. At this point, go ahead and serve immediately.
