Ingredients

  • 3 Pound London Broil Roast
  • Salt and pepper
  • 2 Tablespoons Butter
  • 1 Tablespoon Avocado oil (Click here for my favorite brand on Amazon)
  • 1 Small onion, diced
  • 2 Garlic cloves, minced
  • 1/2 Cup Beef broth
  • 2 Tablespoons Tomato paste
  • 2 Tablespoons Balsamic vinegar
  • 2 Tablespoons Brown sugar use sugar free for keto
  • 1 Tablespoon Worcestershire Sauce

Instructions

  • Season both sides of the London broil generously with salt and pepper.

Searing the London Broil:

  • Using the sear function on your slow cooker or a large skillet over medium-high heat.
  • Heat the slow cooker or the skillet and add in the butter and avocado oil.
  • Sear the London Broil for a few minutes on each side, or until each side is browned.
  • With the roast in the slow cooker, add in the onion and the garlic.

For the Balsamic Mixture:

  • In a small bowl, mix together the beef broth, tomato paste, balsamic vinegar, brown sugar and Worcestershire. Pour the mixture over the roast.
  • Cook in the slow cooker on low for 8 hours, or high for 4 hours.
  • When finished, shred with two forks and serve with mashed potatoes or mashed cauliflower.

Notes

  • Use the remaining liquid left in the slow cooker to make a gravy.  You can whisk in 1/2 teaspoon Xanthan gum for keto and bring the liquid to a boil or make a slurry with 1 tablespoon of corn starch and 1/4 cup of water whisked together and added to the gravy, then brought to a boil to thicken.
