What Is London Broil?

London broil is a type of beef dish that originated in the United States, despite its name. Contrary to popular belief, it does not refer to a specific cut of meat but rather a cooking method. London broil is typically made using top round steak, which is a lean cuts of beef.

To prepare London broil, the meat is marinated for several hours or overnight to enhance its flavor and tenderness. The marinade usually consists of ingredients like soy sauce, Worcestershire sauce, garlic, olive oil, vinegar, and various herbs and spices.

Once marinated, the meat is cooked using high heat methods such as grilling or broiling. It is important to note that London broil should be cooked quickly at high temperatures to achieve a medium rare or medium doneness while still maintaining its juiciness. Overcooking can result in tough and dry meat.

After cooking, London broil is traditionally sliced thinly against the grain before serving. This helps to further tenderize the meat and make it easier to chew. The resulting slices are flavorful with a slightly charred exterior and juicy interior.

London broil can be served as a main course alongside vegetables or salad. It pairs well with side dishes like roasted potatoes or rice pilaf. Leftover London broil can also be used in sandwiches or salads for added protein and flavor.

Overall, London broil offers a delicious, budget friendly, way to enjoy lean cuts of beef with robust flavors. Its versatility makes it suitable for casual gatherings or special occasions alike.

London Broil Marinade

Our marinade for this recipe is super easy but incredibly important. When it comes to London Broil, its not the highest quality steak so the marinade will help tenderize it, making it far more appealing and flavorful. You do not need to get overly complex with the marinade but you also don’t want to short change the time you marinade. A solid overnight time period is best, if you are short on time, 3-4 hours is really what you want as your minimum.

Here is your list of ingredients for the marinade:

  • red wine vinegar
  • olive oil
  • Worcestershire sauce
  • BBQ sauce
  • Minced Garlic

One suggestion I make with this marinade or any other, rotate the bag so that you ensure all parts of the meat are being covered. Every couple of hours, especially if you are marinating it overnight.

After getting an overnight or 3-4 hours of marinade, take the marinated London Broil and we are going to remove it from the container. We are next going to add some SPG rub, don’t even pat it dry, simply add the SPG rub to the London Broil as is. If you do not have an SPG rub, equal parts, of salt, black pepper and garlic is all you need to make your own. Do not get overly aggressive with the rub, we already have a lot of flavor in there with the marinade, this is just a secondary flavor to compliment the marinade.

How To Grill London Broil

For this London broil recipe we are going with an indirect cooking method to start and then a quick sear over direct heat. For this recipe I have used both my gas grill and my Weber Kettle, the same principles apply for this recipe, regardless of whether its on charcoal or gas.

Start off setting your grill up with two zones. You will want an ambient temperature of 300° on the grill. While you wait for the grill to get up to our desired temperature, leave the London Broil out and let is work its way up to room temperature. Once the grill is up to temperature, the London Broil should be ready to go. Place it on the cool side for indirect cooking and you will leave it there for about 40 minutes, until it reaches an IT of 110°.

When the grilled London Broil reaches 110°, briefly remove it from the grill, crank up the heat to 400°. This should not take long and then we are going to sear the London Broil. You are going to sear for about 3 minutes on each side.

If you need a quality unit to track your IT on the London Broil and grill, try the ThermoPro TP20. It has yet to disappoint me!

After 3 minutes on each side, you will pull this right around 135° and then let it rest for about 10-15 minutes. After the rest period, you can start to slice and serve. I recommend slicing across the grain, allowing for a more tender piece of meat to enjoy!
