Cooking a London Broil on a Pellet Grill

Do you like London Broil and wondering about how to cook a London broil on a pellet grill? Well! Then this blog post is for you. London Broil is thinly sliced beef from the flank or underbelly of the cow. 

It can be cooked in many different ways but it’s most famous for being grilled with the marinade of onion, garlic, and Worcestershire sauce. In this post, we’ll make a marinade for our London Broil and then grill it on a pellet grill.

How to Cook a London Broil on a Pellet Grill

Here we will share a recipe for cooking a London broil along with the ingredients and directions required. 

Ingredients you may need:

  • London Broil Steaks
  • Soy sauce 
  • Worcestershire sauce
  • 1 medium-sized onion (chopped)
  • 1 tbsp garlic (minced)
  • Kosher salt
  • Onion powder
  • Paprika 
  • Garlic powder 
  • Granulated sugar  
  • Black pepper 

Directions:

First, we’re going to create our marinade by combining equal amounts of Worcestershire sauce and soy sauce in one bowl. And then add minced garlic and chopped onions into another bowl. We’re going to mix it all in a wine bottle.

Next, we’ll add the rub to the pan. We’ll mix up everything we put in our marinade and then put it into this one bowl. Our rubs may include kosher salt, pepper, onion powder, garlic powder, paprika, and granulated sugar. 

We’ll also add Worcestershire sauce and soy sauce for flavour. Once again we want to seal up the bowl and get it into our refrigerator as soon as possible. As the beef is marinated and our rub is created, we’re going to want to prepare the grill. We are going to set it up for 2-zone cooking at medium heat.

As we have our grill prepped, we’ll start with a cold pan. We don’t want the meat hitting a hot pan or it will stick and ruin our London Broil. We’ll then sear the top side of our piece of meat for about 5 minutes before flipping it over onto the cool side of the grill.

This will also help us to create a nice crust on both sides of our piece of beef. Since we don’t have a thermometer in our pellet grill, we can watch our cooking times and temperature by using the colour change technique. We’ll finish our piece of beef off at about 140 degrees on the inside for medium-rare. 

Once we’ve finished grilling a London Broil, let it sit for about 5 minutes so that all those good juices have time to soak back into our meat. This London Broil is delicious either served alone or with some grilled vegetables.

Smoked London Broil with Green Salad and Garlic Bread

This is a delicious way to cook a London Broil, with or without the Worcestershire marinade. The marinade is also great on chicken or turkey breast and steak. 

Ingredients 

  • 1 Tbsp. ground black pepper 
  • 1 Tbsp. onion powder 
  • Garlic bread
  • 2 tsp. granulated sugar 
  • 1 tsp. salt 
  • 1 tsp. garlic powder 
  • Green salad
  • 1 tsp. paprika 
  • 2 tsp. Worcestershire sauce 
  • 2 Tbsp. soy sauce 
  • 2 London Broil steaks

Instructions

  1. Combine all ingredients for the marinade in one bowl and whisk together until combined. 
  2. Put the steak into a large Ziploc bag (or another sealable container) and pour the marinade into it so that it’s fully submerged in the marinade. Seal and place in the refrigerator for at least 6 hours or overnight. 
  3. Combine all ingredients of your rub in a mixing bowl, including Worcestershire sauce and soy sauce, and mix with a spoon until well combined. 
  4. Once the steaks are marinated and the rub is ready, preheat your smoker at medium heat. 
  5. After preheating, turn the smoker off for a few minutes so that it reaches about 140 degrees. 
  6. Brush or spray oil onto both sides of your London Broil steak and then sear it in a hot pan on both sides to get some nice grill marks. 
  7. Next, flip it around onto a cool part of the grill so you can finish cooking it on the opposite side. Cook until the internal temperature reaches 140 degrees for medium-rare. 
  8. Let sit for about 5 minutes before serving. 
  9. This is great served with grilled vegetables like brussels sprouts and corn with some crusty bread to sop up all the sauce.
