How to Smoke a London Broil (In 5 Easy Steps)

Sharing is caring!

Do you want to smoke a London broil? It’s one of my favorite recipes for an easy, cheap, and flavorful steak.

However, the tough cut needs some extra love! So follow my easy step-by-step guide on how to smoke London broil style.

Can You Smoke London Broil?

Yes, you can smoke London Broil. This process will help to add a rich, smoky flavor. Usually, London Broil is marinated and broiled or cooked on the grill, but it can also benefit from smoking.

I want to set the record straight right now. London broil is a marinade, not a particular cut of meat or type of steak. Oh, and it isn’t from London!

It is, though, a fantastic way to get the flavor in cheaper cuts of beef with tough meat fibers. When combined with smoking, it delivers a delicious and economical meal.

The term ‘broil’ refers to a method of cooking that exposes the meat to high heat, but we won’t be doing that today as we want to smoke it.

Smoked London Broil Marinade

Before you smoke a London broil, you need to allow it to marinade for 4-8 hours before you cook it in the smoker.

This marinade will help to season and tenderize the meat. The result is a cheaper piece of meat that is as juicy as your favorite wagyu ribeye steaks!

Place all ingredients in a bowl or a large zip-lock bag. Add the meat to the marinade and ensure it is evenly coated. Place in the fridge for 4-8 hours.

The marinade has common pantry staples, which are listed below:

  • 2 pounds beef top round roast
  • 3 tbsp Balsamic vinegar 
  • 1/4 cup of Worcestershire sauce
  • 6 minced garlic cloves
  • 1/2 cup of olive oil
  • 2 tbsp of light soy sauce 
  • 1 tbsp fresh oregano
  • 4 tbsp of honey
  • 2 tbsp black pepper 
  • 2 tbsp kosher salt
  • 1 Bay leaf 
  • 1 tsp chili pepper flakes

How to a Smoked London Broil

Below are my simple four steps for smoking a London broil. Just ensure you allow enough time for the meat to marinade, then fire up the smoker, and you’ll be ready to cook.

Step 1: Preheating Your Smoker

– Ensure your smoker or pellet grill is clean from the previous use and the load with your wood chips.

– Set the temperature to 225°F

Step 2: Smoking

Remove the meat from the marinade and give it a light shake over the sink. This will remove the excess moisture and herbs. Rub it with salt and pepper.

Put the meat on the cooking grate in the pellet grill, and insert the temp probe to the thickest part to monitor the internal temperature. 

 You will need to smoke the London broil for about 45 minutes. Remove it when the meat has reached 125°F (for rare) 132°F (for medium-rare), or 140°F (for medium). The cooking time will also vary depending on the thickness of the meat. 

Step 3: Rest The Meat 

– When the meat is ready, remove it from the pellet grill and let it rest for 15 minutes, covered

Step 4: Serve & Enjoy 

Most people slice the London broil against the grain thinly; however, you can serve it how you like. Make sure you serve with your favorite side dishes.

How Long to Smoke a London Broil

At 225°F, it will take 40-50 minutes to smoke a London broil to medium rare. However, this timing will vary depending on the thickness of the meat and the type of smoker you use.

You should use a meat thermometer to monitor the internal temperature of the meat. Remove it when it has reached 125°F (for rare) 132°F (for medium-rare), or 140°F (for medium).

What Temperature Do We Smoke a London Broil Steak?

The ideal temperature for a London broil is 225°F. Any hotter, and the meat will cook too fast, resulting in tough meat.

What Internal Temperature Does the Meat Need to Be?

Remove when the meat has reached 125°F (for rare) 132°F (for medium-rare), and 140°F (for medium).

Using an internal meat thermometer is the best way to measure the cooking temperature and avoid dry or overcooked meat.

How to Prepare a Smoked London Broil Steak?

You want to allow at least 4 hours for marinating, but if you can leave it for 8 hours, that would be ideal.

Should You Brine a Smoked London Broil Steak?

Steak brines are a good way to flavor and tenderize cheaper cuts of meat. However, if you don’t for this recipe, we do not recommend brining it as the marinade is enough.

Should You Trim a Smoked London Broil Steak?

London broil is a cheaper cut, so the meat may need to be trimmed of any silver skin or excess fat before marinating.

Want to Try Sous Vide London Broil

Sous vide London broil is another great way to cook it. The low and slow method leaves you with melt-in-the-mouth meaty!
