London Broil in the Crock Pot
This London Broil crock pot recipe is for those of you who purchased a London Broil cut of meat from the local grocery store and wondered what to do with it. Let me show you my favorite way to cook this lean cut of beef with little effort.
Traditionally, London Broil isn't a cut of meat, but a cooking technique for cooking tough cuts such as flank steak or top round steak. Slow cooking London broil helps relax the muscle fibers.
The traditional method is to marinate the roast, and then sear the meat like a steak and cut it against the grain in thin strips.
I think the best way to cook this piece of meat is until fall-apart tender, just like you would a slow cooker pot roast.
London Broils are a leaner and tougher cut of beef, which makes it hard to keep tender. This makes it a perfect choice for this slow cooking method... to keep it nice and tender in savory juices while it cooks!
How to make London broil fall apart tender
Fork-tender London Broil requires a long cooking time for best results. 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 cast iron pan or large skillet over medium-high heat or a dutch oven.
Now we can add in the butter and avocado oil and do a quick sear on both sides for 1-2 minutes to get a brown crust.
Now, with the London Broil roast in your slow cooker, add in the onion and the garlic on top of the meat. I love to use frozen diced onion for even easier prep time.
Making the Balsamic Sauce:
Some have said the balsamic sauce is so good they wished they had doubled it!
In a small bowl, mix together the remaining ingredients: beef broth, tomato paste, balsamic vinegar, brown sugar and Worcestershire.
Pour this mixture over the roast.
Cook in the slow cooker on low for 8-10 hours or high for 4 hours, or until the meat is fork tender. For an even quicker cook time, cut the roast into smaller pieces before slow cooking.
When finished, shred with two forks and serve with mashed potatoes, green beans, homemade bread or mashed cauliflower.
This crockpot London boil is a perfect make-ahead meal that will please the whole family!
- Steamed or roasted vegetables.
- Add baby red potatoes or baby carrots to the slow cooker with the roast.
- Noodles! The sauce would be amazing over egg noodles. You could even thicken it up with a cornstarch slurry.
- your favorite kind of rice.
- Keto Mashed Potatoes (cauliflower)

- 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.
