London Broil Smoker Recipe with Garlic and Red Wine Marinade

london broil sliced
To make smoked London Broil steak, coat your meat with a marinade that includes salt, garlic, red wine vinegar, olive oil, and black pepper and let it rest for 4 hours. Smoke the marinated meat at 225°F until the internal temperature reaches 145°F.

The origin of the name “London Broil’ is obscure because this is a North American dish and has nothing to do with the English city. Many cooks will agree that London Broil is a cooking method and not a cut of meat because different cuts of meat can make a London Broil. Any large tough cut of meat such as flank steak or top-round steak can be a London Broil provided it is marinated overnight and broiled the next day.

Why London Broil Should Be Marinated Before Smoking

You should marinate London Broil to tenderize the meat and add bold flavor. To prepare your own marinade, begin with olive oil or vegetable oil and then add lemon or orange juice, Worcestershire sauce, soy sauce, apple cider vinegar, or red wine vinegar. 

As with a dry rub, you can make your marinade using a combination of pepper, salt, brown sugar, chili powder, and aromatic seasonings such as garlic powder and onion powder. 

A marinade is preferred over a dry rub because the acidic ingredients help to break down the tough connective tissue in this piece of meat. Marinate this tough cut of meat for at least 4 hours or overnight – the longer you marinate it, the more tender it will be.

Units Scale
  • 2 lb London Broil
  • 1/2 cup olive oil
  • 1/4 cup honey
  • 1/4 cup apple cider vinegar or red wine vinegar
  • 2 tsp Worcestershire sauce
  • 1 1/2 tsp black pepper
  • 1 tsp red pepper flakes
  • 1/2 tsp kosher salt
  • 5 cloves minced garlic
  • 5 sprigs thyme
  • 2 tsp high-heat vegetable oil such as Avocado oil

  2. Place the meat in the marinade, ensuring it is well-covered. Place in the refrigerator overnight.
  3. Preheat the smoker to 225°F. Use cherry, oak, hickory, or pecan wood chips or pellets to infuse plenty of smoky flavor into the meat.
  4. Drain the marinade and place the meat directly on the grill grates. Close the lid and smoke for 45 minutes.
  5. Remove the meat from the smoker once the internal temperature hits 125°F (rare) or 135°F (medium rare).
  6. If you want the meat to form a nice crust, fire up a cast-iron skillet over moderately high heat to sear. Add a few teaspoons of a high-heat oil such as Avocado oil.
  7. Place meat in the pan and sear on both sides for 2 to 3 minutes per side.
  8. Transfer the meat to a cutting board and rest for 5 to 10 minutes. Using a sharp knife, slice your meat into thin pieces against the grain. Enjoy!
