Ingredients

  • 3 Pound London Broil Roast
  • kosher salt and pepper
  • 2 Tablespoons Butter
  • 1 Tablespoon avocado oil
  • 1 Small onion, diced
  • 2 Garlic cloves, minced
  • ½ 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.

  • 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.

Notes

  • 3 Lb London Broil Roast - This roast doesn't have much fat, a you could also use a chuck roast for a fattier option. Either are a good cut of meat. The amount of fat is just a personal preference.
  • Use the remaining liquid left in the slow cooker to make a gravy.  You can whisk in ½ teaspoon Xanthan gum for keto and bring the liquid to a boil or make a slurry with 1 tablespoon of corn starch and ¼ cup of water whisked together and added to the gravy, then brought to a boil to thicken.
  • Make this slow cooker London broil in the Instant pot for a quicker cook time. Follow all of the steps using your instant pot instead of the slow cooker. Instead of cooking low and slow, pressure cook on high for 35 minutes, followed by a 10 minute natural pressure release. If the roast is not fork tender, cook under high pressure for 10 minutes more, followed by another 10 minute natural release.
