I think I found my favorite way to cook steak in the crock pot today. I decided to make our favorite London Broil Roast in a Crock Pot. Crock Pot London Broil turns out so moist and tender cooked in the slow cooker.
My old favorite recipe for London Broil is to roast it with potatoes and carrots in a roasting pan that has been tightly wrapped in aluminum foil.
It was the best way to cook London broil.
I make a pork loin this way.
I even roast a Thanksgiving Turkey breast this way.
The aluminum foil traps all the moisture in the pan and the meat turns out fall apart tender.
Now I am not so sure I will ever roast meat that way again.
I have become obsessed with my crock pot slow cooker.
I keep trying to find new crock pot recipes to cook.
I converted my mother's meatloaf recipe into a Crock Pot Meatloaf recipe.
Dinner time has become so much easier since I have started cooking in a crock pot each week.
Enough of my crock pot obsession.
Let's get to the Crock Pot London Broil recipe.
That's what you're here for, right?
How to make Crock Pot London Broil
Like most crock pot recipes, this is a dump it and forget it recipe.
You will need a nice piece of London Broil, baby red potatoes, baby carrots, beef broth, an onion, garlic, a couple of bay leaves and a 6-quart crock pot.
I like to brown beef before I add it to the crock pot but this step can be skipped if you don't feel like doing it.
But it does give the meat a nice color.
Add 1 tablespoon of butter to a skillet on high. Place the London broil in and brown the first side.
Flip it over to brown the other side.
Place the London Broil into the bottom of an (affiliate link) 6 quart crock pot and lay the sliced onion and garlic cloves on top of the roast.
Salt and pepper the top of the meat and onion slices.
Next add the baby red potatoes, baby carrots, bay leaves, salt, and pepper.
Pour the beef broth in around the London broil.
Put the lid on the crock pot and cook for 4 hours on high or 8 hours on low.
Check the potatoes for doneness by piercing with a fork.
If they are still a little firm cook another 30 minutes.
To make a gravy mix the water and cornstarch.
Pour it into the crock pot and return the lid.
Cook another 15-30 minutes on high to thicken the gravy.
You could also remove the London broil and vegetables and ladle the liquid into a small saucepan and bring to a boil until thickened.
Place the London Broil on a serving platter and carve.
Nestle the potatoes and carrots around the roast.

Recipe Expert Tips
- Do not over cook or the roast will be dry.
- Rest the meat a few minutes before carving. This will make the meat easier to slice.

I have med too big red potatos how many potatos and how would you thow them in the crockpot

Holly
You can use as many potatoes as you need to feed your family. A large red potato is about the equivalent of 3 to 4 small red potatoes.
Colleen
Awesome recipe! I added a small can of whole peeled tomatoes and a tsp of gravy master to darken the sauce a bit. Great autumn meal that’s easy. Thank you!
Arlene Mobley
Collen
That sounds delish. I am going to have to try your version. So glad you loved the recipe!
Leslie
Trying this today, I cook for myself and my parents. My mom said she’s never been able to make a tender London broil...and she’s said let’s hope. My goal is to prove her wrong. Very easy to follow. Glad someone asked about the bay leaves I forgot to add them, had to put them on top
Arlene Mobley
I hope it turns out wonderful for you Leslie!

I have been making London broil in the crockpot for years..but I have some easy tips...I use 2 env of lipton onion soup mix with 2-3 cups of water..so you don't have to use the onion ..this is the only seasoning you need....add the potatoes and carrots...after cooking on LOW for the 8 hrs..I remove the meat and vegs and add 1(or 2) env of brown gravy mix and whisk until mixed in the crock pot..put the lid back on and cook while the meat is resting whisking a few times.
Kris
I made this for the second time tonight and, as usual, I overcooked enough that it didn't slice very well but it was tender and delicious. I never thicken the liquid for gravy, I use it as au jus for the meat and vegetables. When I test the meat and it feels resistant, I always assume it's not done enough. I wish I could figure out how to cook it just to slicing doneness. Can anybody help?
Arlene Mobley
London broil can be finicky but if you think it is done when you check it with a fork it probably is even though there is some "resistance". London broil should rest about 10 to 15 minutes before slicing.
So I would suggest taking it out of the crock pot when it is fork done so it doesn't over cook and shred when you try to slice it. Let it rest and then try slicing it.
Are you slicing it on the diagonal? You should slice it against the grain with a very sharp knife. That could also be why it is shredding.
My recipe calls for a 2-3 pound London broil. Are you cooking the same size roast? If so cook it for the 4 hours, make the gravy if you like following the directions. If the roast is on the smaller size you can remove it from the crock pot before making the gravy to prevent over cooking. Good luck! Let me know if you have any other questions!

This was quite good. I've never cooked a whole meal on High before and was a little nervous, but it was great. Tender and delicious.

Kris
So glad you enjoyed the recipe! Thanks for the 5 star rating!
rena
I want to try this out tomorrow. I won't be able to cook it for 8 hours though so I will have to try 4 on high. If I want to add sliced mushrooms should I add them at the beginning or wait until closer to the end? Thanks!
Arlene Mobley
Hi Rena
If the mushrooms are thinly sliced I would add them for the last hour of cooking time.
rena
Thanks for the response. I didn't have time to add them as I wasn't home. The meat was overcooked and I am guessing that my slow cooker is smaller then 6 qts. We still liked it but had to cover the meat in the gravy. Next time I will cook it less then 4 hours on high or try 8 hours.
Arlene Mobley
Rena
Sorry to hear that. Yes the size of the meat will make a big difference in how long it needs to cook.
rebecca koretz
I cooked it on high for the 4 hours but it was very tuff as it was getting late we decided to have it tomorrow any recommendations how to heat it up and make it more tender? I hope the meat is not ruin the carrots are very hard still and the potatoes seem like they could of cooked maybe a little bit longer.... Help
Arlene Mobley
Rebecca sounds like your roast may have bigger than the one used in this recipe. Or maybe your crock pot isn't working correctly. The vegetables should have been cooked after four hours.
Terry
I am so excited to try this recipe, London broil roasts were on sale at my local store buy one get one free so couldn't resist that sale. Have never fixed a London broil and didn't know what to do with them so did a google search and came upon your recipe. Sounds wonderful and so easy!
Arlene Mobley
Terry I hope you enjoy the recipe! Not sure what I love more a delicious Crock Pot LOndon Broil for dinner or a buy one get one sale!
Samantha
Hi, I was so excited to find this recipe as London broil is one of my favorite meals and I just got a crock pot this past christmas so what better way to use my new gift! I did everything as listed but cooked on high for 4 hours because I'm impatient (lol) and the meat was quite tough. Not inedible, but definitely not as tender as it would have been if I cooked on low for 8. Any tips for the future when pressed for time and using high for 4 hours? Or for this recipe should I just stick to low and slow?
Arlene Mobley
Hi Samantha
Sorry to hear your London broil ended up being tough. London broil turns out so tender when you cook it low and slow so I would stick with the 8 hour cooking time. The way you slice the meat also makes a difference in how tender it is also. London broil should be sliced against the grain at a slight angle. I hope you give the recipe another try!
Debbie
I'm making this for Valentine's dinner tonight. The printed recipe does not tell when to add the bay leaves, but I figured they should go after the carrots. Not sure if you should let the london broil rest before slicing so I will try that and hope it doesn't shred. But either way I am excited!
Arlene Mobley
Debbie
Hope you enjoyed the recipe. Yes the bay leaf goes in at the beginning and I usually do let my roasts rest for a few minutes before slicing.
Debbie
Arlene, it was FANTABULOUS!!! This will be my go-to recipe for london broil in the future! You ROCK girlfriend <3
Arlene Mobley
Debbie
Thank you so much! I am so excited to hear you were happy with the recipe.
Michelle
So I tried this tonight .... instead of using beef stock I used a watered down marinade. Well needless to say I no longer have a london broil that can be sliced it had to be shredded. I was told that it tasted more like a pot roast . I am glad it was edible after al that lol.
Arlene Mobley
Michelle
It sounds like you cooked it a bit too long. Size of london broil and the size of the crock pot you used can change the cooking time. I bet it still tasted delicious.

Am making this as I type. Only variation, I added a couple of celery stalks. Has already passed the taste test. Many thanks for sharing.

Made this last night and it was yumm-o! I did not brown the meat (too lazy, and that would have been another dish to wash!☺), cooked on low for 7 hours. The meat fell apart, so we shredded it in the crock pot and ate out of big bowls. Probably the easiest thing I've ever made in my crock pot...just had to slice (not even dice!) an onion! Thanks!
Arlene Mobley
Tracey
I am so happy to hear you enjoyed the recipe!
Julie Wood
I have seen London Broil for good deals at the store lately. I have never had success in cooking this meat on the stove top because it always turns out tough! But I can see that this meat can get tender in the crock pot and such an easy recipe. I love this awesome recipe! Thanks for sharing. I will have to make it! Do you know that your email always goes to spam. I wonder why!
Arlene Mobley
Julie
Thank you I hope you enjoy the recipe. I have no idea why my email is going to spam all of a sudden. Thank you for letting me know. I will have to investigate and try to figure out why.
