Smoked London broil might sound like something you’d order at a steakhouse, but it’s way easier than it looks, and the payoff is big. This budget-friendly cut transforms into smoky, tender beef with just a little patience and a lot of flavor. And the real kicker? A rich, savory gravy that soaks into every slice like it was made to be there.
This isn’t just backyard grilling, it’s low-effort show-off food that tastes like you knew exactly what you were doing.
Don’t Forget the Gravy!
This Smoked London Broil is topped with an optional (but highly recommended!) savory, velvety gravy made with the marinade. This recipe pairs perfectly with veggies like my Crockpot Mashed Potatoes and Roasted Asparagus.
The recipe only needs a few ingredients. The smoked London Broil gets marinated in a delicious marinade that doubles as a savory flavoring for gravy. Afterwards, the marinated beef gets smoked over low heat to get a smoky flavor, then finished with a higher blast of heat for the perfect finish. Easily one of our favorite smoker recipes!

- Super flavorful and tender
- Versatile – can be served hot or cold in a variety of ways
- Highly requested at all barbecues

Recipe Tips
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.
Internal temp: 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.
