Combine all the ingredients for the marinade. Remove ¼ cup of the marinade and reserve for later if you want to make gravy. Place the rest of the marinade in a resealable plastic bag.

Add the London Broil to the bag. Seal the bag and place it in the refrigerator for 6 to 10 hours. When it is finished marinating, pat it dry with paper towels.

Place the roast directly on the grill grates, smoke for 50 minutes, then turn the heat up to 450°F and cook for an additional 10 to 35 minutes. Let it rest for 10 minutes before slicing.

For the Gravy:

1. Melt the butter in a saucepan or skillet over medium heat. Whisk in the flour and stir for 1 minute.
2. Slowly pour in broth while whisking constantly, and stir until smooth.
3. Add reserved marinade, pepper, and salt and simmer for 3-5 minutes while stirring.
4. Remove from heat and serve.

Tips for Success

• Plan ahead so you have plenty of time to let the roast marinate. Since London Broil usually uses a very lean piece of meat, it will need some help from the marinade to make it tender.
  
• The cooking time will vary depending on the thickness of your cut of meat. Use an instant-read thermometer for best results.
  
• Lean cuts of beef used for London Broil are best served rare to medium rare. If you prefer your beef cooked well-done, we recommend cooking the London Broil like a brisket and leaving it on the grill until the interior temperature reaches 205°F.
  
• Slice the meat against the grain as thinly as possible.

Instructions 

• Combine all the ingredients for the marinade. Remove ¼ cup of the marinade and reserve for later if you want to make gravy. Place the rest of the marinade in a resealable plastic bag.
• Add the London Broil to the bag. Seal the bag and place it in the refrigerator for 6 to 10 hours. 
• Preheat the pellet grill to 200°F. 
• Remove the London Broil from the marinade and pat it dry with paper towels. Discard the marinade that the meat was soaking in.
• Place the roast directly on the grill grates. 
• Smoke for 50 minutes then turn the heat up to 450°F.  Cook for an additional 10 to 35 minutes or until an internal meat thermometer reads 125°F for rare, 132°F for medium rare, or 138°F for medium. The cooking time will vary depending on the thickness of the meat. 
• Let the roast rest for 15 minutes the slice it as thin as possible. Make sure you slice the meat against the grain. 

For the Gravy

• Melt the butter in a saucepan or skillet over medium heat. Whisk in the flour and stir for 1 minute. 
• Slowly pour in the broth, about ¼ cup at a time, while whisking constantly. Whisk until the mixture gets smooth before adding more broth, then repeat until all the broth is added.
• Add the ¼ cup of reserved marinade, pepper, and salt. Simmer for 3 to 5 minutes, stirring continuously until thickened. 
• Remove from heat and add additional salt and pepper if desired. Serve with the London Broil. 

Notes

If you like your beef well done, we recommend leaving the roast in the smoker until the internal temperature reaches 205°F. It will be well done when it reaches 150°F, but since it is such a lean cut of meat, cooking it to 150°F will make it tough. By continuing to cook it to 205°F, the fibers will have a chance to break down and tenderize.
