This recipe is for those of you who purchased a London Broil cut of meat from the grocery store and wondered what to do with it.

Traditionally, London Broil isn’t a cut of meat, but a method for cooking tough cuts such as flank or top round steak.

The traditional method is to marinate the roast, and then sear the meat like a steak and cut it against the grain to serve.

I prefer to cook mine until fall apart tender in a slow cooker.

London Broils are a leaner and tougher cut of beef, which makes it hard to keep tender. This makes it a perfect choice for your slow cooker… to keep it nice and tender in savory juices while it cooks! Seared to lock in the flavor and slow cooked to perfection! This slow cooker London Broil recipe is great for those busy weekdays! Super easy prep time and set it and come home to a hearty meal for the whole family. Who doesn’t love that? This is going to be so delicious!

Let’s get started!

How to make London broil fall apart tender

Let’s first start by seasoning both side of the roast generously with salt and pepper.

Sear the London Broil:

If you have a slow cooker that has a sear function, go ahead and pre-heat that. If you do not have a slow cooker with a sear function, you can use a large skillet over medium-high heat.

Now we can add in the butter and avocado oil and sear the roast on both sides for a few minutes to get a brown crust.

Now, with the London Broil roast in your slow cooker, add in the onion and the garlic. I love to use frozen diced onion for even easier prep time.

Making the Balsamic Sauce:

In a small bowl, mix together the beef broth, tomato paste, balsamic vinegar, brown sugar and Worcestershire.

Pour this 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.

This crockpot London boil is a perfect make-ahead meal that will please the whole family!

INSTRUCTIONS

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.

JENNIFER'S TIPS

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.
