Choosing the Right Cut of Meat

Before we dive into the grilling process, it is important to select the right cut of meat for your London Broil. The most commonly used cuts for London Broil are flank steak or top round steak. It is recommended to look for high-quality meat, ideally organic or grass-fed, to ensure the best flavor and tenderness.

Preparing the Steak

Once you have chosen the right cut of meat, there are a few steps to follow before grilling. First, it is important to consider the thickness of the steak. Since London Broil is cooked over high heat, the steak should be less than 1-inch thick. This ensures that the meat gets cooked evenly and retains its juiciness.

To enhance the flavor and texture of the steak, it is recommended to marinate it for at least one hour. A simple marinade consisting of minced garlic, balsamic vinegar, Dijon mustard, Worcestershire sauce, dried Italian seasonings, salt, pepper, and crushed red hot red pepper flakes can do wonders for the taste of the meat.

Preheating the Grill

Before you start grilling, make sure to preheat your gas grill completely. This step is crucial to ensure that the steak gets a nice sear on the outside while remaining tender and juicy on the inside. Gas grills are known for their ability to sear meat better than electric grills because they provide a continuous source of heat.

The Grilling Process

Now that you have preheated your grill and marinated the steak, it’s time to start grilling. Here are the steps to follow:

  1. Remove as much marinade as possible from the steak by patting it dry with a paper towel. This will prevent the steak from steaming and help achieve a nice char on the outside.
  2. Place the steak on the hot grill at a 45° angle. This will create beautiful sear marks on the meat.
  3. After a few minutes, rotate the steak 90° to create a cross-hatch pattern. This not only adds visual appeal but also ensures even cooking.
  4. Cook the steak to the desired doneness. The cooking time will vary depending on the thickness of the steak and your preferred level of doneness. A general guideline is to grill the steak for about 6-8 minutes per inch of thickness for medium-rare.
  5. Once the steak is cooked to your liking, remove it from the grill and let it rest for 5-10 minutes. This allows the juices to redistribute and results in a more tender and flavorful steak.
  6. Before serving, make sure to cut the steak against the grain. This breaks up tough fibers and further tenderizes the meat.

Temperature and Tips

Grilling London Broil on a gas grill requires high heat to achieve the desired sear and texture. According to the sources, the recommended gas grill temperature ranges from medium-high heat to 500 degrees Fahrenheit. It is best to follow the specific instructions provided by your grill manufacturer.

Here are some additional tips to keep in mind:

  • Bring the steak to room temperature before grilling. Letting it sit for about 30 minutes allows for more even cooking throughout the steak.
  • Season the meat with salt, pepper, and other desired spices to enhance the flavor.
  • Always cut the steak against the grain before serving to break up tough fibers and tenderize the meat.


Grilling London Broil on a gas grill can result in a delicious and satisfying meal. By following the proper techniques and tips, you can achieve a tender and juicy steak with a beautiful sear. Remember to choose a high-quality cut of meat, marinate for flavor, preheat the grill, and cook the steak to the desired doneness. Letting the steak rest and cutting against the grain are essential steps for a perfect London Broil. Enjoy!
