Crock Pot London Broil - cooked to perfection in your slow cooker. This Family Favorite Crock Pot recipe is tender, juicy and with just enough gravy to serve over buttered noodles or homemade mashed potatoes. Let me show you how tender this cut of beef turned out cooked in a slow cooker.

London broil is one of my family's favorite cuts of beef to grill during the summer. When they're on sale, I always purchase a few to work into my Weekly Meal Plans. Imagine my surprise when I found one in my freezer during the middle of a snow storm!
I knew I had to use it, however, there was no way I could get to my grill with all the snow currently falling outside.
I really didn't want to put it in the oven to make the meat even tougher. Therefore, I pulled out my crock pot and slowly cooked it all day. Served over mashed potatoes and jalapeno corn muffins, this was an amazing tender piece of meat that made a fabulous meal.
Is London Broil a Good Cut of Meat?
Yes and no. Traditionally speaking, London broil is a great money-saving option for family meals. Especially if you're cooking for a large family or you're on a budget. However, because it's a lean muscle cut, it also tends to be tougher due to its low fat content.

- 1 ½ pound London Broil
- Vegetable oil
- Beef broth
- Sliced onions
- Salt and pepper to taste
- Chopped garlic
- 1 tbsp. cornstarch mixed with 2 tbsp. cold water - we're going to use this as a slurry to thicken the broth towards the end of cooking.

Cooking Tip: prepare a "slurry" to help thicken the broth towards the end of cooking.
Directions
- Add a few tablespoons of vegetable oil to a large skillet and brown the London broil on both sides; seasoning with salt and pepper.
- Remove the London broil from the skillet and place in the crock pot, followed by the onions, garlic and beef broth.
- Cook on high for 4 hours or on low for six hours. Remove the meat from the crock pot when it is tender that a knife can easily be inserted into the middle.
- Add the cornstarch and water mixture to the crock pot and continue to cook for another 15 to 20 minutes or until the broth thickens.
- Slice the London broil and place on a platter. Serve with the gravy and onions on top.

London Broil Crock Pot Serving Tips
- Slice the London broil thin before serving. I like to saute onions in butter and Worcestershire sauce until translucent. You can also add chopped mushrooms and saute those with the onions as well.
- Make slider sandwiches with the cooked crock pot London Broil. Using two forks, shred the beef when it's done cooking and then add it to small rolls and top with barbecue sauce.
Frequently Asked Recipe Questions
The answer to this question is no. London Broil is different from pot roast because it has very little fat. Which is why most people cook it on the grill.
London Broil and a few other cuts like flank steak and top round steaks are usually less expensive because they are tough and lean.
When you usually cook London broil over direct heat, such as grilling, the high heat makes the meat more firm and it will dry out if you cook it too long. However, if you cook meat in the crock pot with liquid, it adds moisture to the cooking and will make the meat more tender the longer you cook it. Which is why this crock pot London broil recipe is so delicious!
