Yield1 London broil roast, sliced into 6 portions


  • 2-3 pounds of London broil
  • 1 onion, thinly sliced
  • 4 cloves of garlic, minced
  • 1 cup of beef broth
  • 1/2 cup of soy sauce
  • 1/4 cup of Worcestershire sauce
  • 2 tablespoons of brown sugar
  • 1 teaspoon of dried thyme
  • 1 teaspoon of dried rosemary
  • 1/2 teaspoon of black pepper
  • 1/4 cup of cold water
  • 2 tablespoons of cornstarch
  • Fresh parsley, for garnish (optional)


  1. Prepare the London Broil:

Start by seasoning the London broil with salt and pepper on both sides. This will enhance the flavor of the meat.

  1. Layer the Ingredients:

In the slow cooker, place the thinly sliced onions and minced garlic on the bottom. These will add a savory base to your London broil.

  1. London Broil in the Slow Cooker:

Lay the seasoned London broil on top of the onions and garlic.

  1. Mix the Sauce:

In a separate bowl, whisk together the beef broth, soy sauce, Worcestershire sauce, brown sugar, dried thyme, dried rosemary, and black pepper. Pour this flavorful mixture over the London broil in the slow cooker.

  1. Set the Slow Cooker:

Cover the slow cooker and cook on LOW for 6-8 hours or until the London broil is fork-tender. Slow cooking allows the meat to absorb all the delicious flavors.

  1. Thicken the Sauce:

About 30 minutes before serving, remove 1/4 cup of the cooking liquid from the slow cooker and mix it with 2 tablespoons of cornstarch until smooth. Return this mixture to the slow cooker, stirring well. This will thicken the sauce.

  1. Slice and Serve:

Once the London broil is tender, remove it from the slow cooker and let it rest for a few minutes before slicing it thinly against the grain. This will ensure maximum tenderness.

  1. Garnish and Serve:

Place the sliced London broil on a serving platter, and if desired, garnish with fresh parsley for a pop of color. Serve with the flavorful sauce from the slow cooker.

This Slow Cooker London Broil recipe is not only easy to prepare but also delivers a mouthwatering, melt-in-your-mouth result. The slow cooker does all the hard work for you, leaving you with a succulent and flavorful dish that your family and friends will love. Enjoy!
