Preparing the Marinade by Mixing Ingredients 

  • In a medium-sized bowl, combine 1/2 cup soy sauce, 1/4 cup olive oil, and 1/4 cup balsamic vinegar. These ingredients create a balanced base with a combination of salty, tangy, and sweet Flavors. 
  • Add 2 tablespoons of honey to introduce a touch of sweetness that complements the savory and acidic elements. 
  • Mince 3 cloves of garlic and add them to the bowl. Garlic adds a wonderful aroma and depth of flavour. 
  • Stir in 1 tablespoon of dried rosemary and 1 tablespoon of dried thyme for herbal notes. 
  • Finish with 1 teaspoon of black pepper to give a bit of heat and spice. 

Mix all the ingredients thoroughly until the honey is completely dissolved and the marinade is well combined. 

Marinating the Grilled Marinated London Broil 

Prepare the Steak: Place your London Broil steak in a resealable plastic bag or a shallow dish. The steak should be large enough to allow the marinade to cover it completely. 

Add the Marinade: Pour the prepared marinade over the steak. Ensure that the steak is fully covered by the marinade. If you’re using a plastic bag, seal it tightly, making sure to press out as much air as possible. If using a dish, cover it tightly with plastic wrap or a lid. 

Refrigerate: Place the marinating steak in the refrigerator. Allow it to marinate for at least 4 hours, though marinating overnight will give the best results. The longer it marinates, the more flavorful and tender the steak will become. 

Getting the Grill Ready: Grilled Marinated London Broil 

Preheat the Grill: While the steak is marinating, preheat your grill to medium-high heat. You want the grill to be around 400°F (200°C). This temperature is ideal for searing the steak and achieving a nice char without overcooking it. 

Clean and Oil the Grill: Make sure your grill grates are clean. You can use a grill brush to scrub them if needed. Once clean, brush the grates with a bit of olive oil to prevent sticking. 

Grilling the London Broil 

Prepare the Steak: After marinating, remove the London Broil from the refrigerator. Let it come to room temperature for about 30 minutes before grilling. This step helps ensure even cooking. 

Remove Excess Marinade: Take the steak out of the marinade and let any excess drip off. You don’t want too much marinade on the steak when grilling, as it can cause flare-ups. 

Season the Steak: Brush the steak lightly with 2 tablespoons of olive oil. This adds a bit of richness and helps with browning. Season both sides of the steak with salt and pepper to taste. The salt will enhance the flavor, while the pepper adds a bit of spice. 

Grill the Steak: Place the steak on the hot grill. Grill for about 6-8 minutes on each side. This timing will give you a medium-rare steak with an internal temperature of about 135°F (57°C). For medium, aim for an internal temperature of 145°F (63°C). 

Check the Temperature: To ensure the steak is cooked to your desired level, use a meat thermometer. Insert it into the thickest part of the steak to check the temperature. 

Resting and Slicing the Steak 

Once the steak has reached the desired temperature, remove it from the grill. Let it rest on a cutting board for about 5 minutes. Resting allows the juices to redistribute throughout the meat, making it more tender and flavorful. 

After resting, slice the steak thinly against the grain. Cutting against the grain will result in more tender slices. If you slice with the grain, the steak may be tougher and chewier. 

Serving Suggestions 

Serve the grilled marinated London Broil slices with your favorite sides. It pairs well with grilled vegetables, a fresh salad, or even mashed potatoes. For added flavor, consider serving the steak with a side of horseradish cream sauce or a sprinkle of fresh herbs.
