Crockpot London Broil

London Broil Slow-Cooker Recipe

1-2 pounds of flank steak

1 can cream of mushroom soup

1 can cream of tomato soup

1 package dry onion soup mix


Place meat in the bottom of the crockpot. In a medium bowl, mix together the two cans of soup. Pour over the beef chunks and sprinkle the onion soup mix on top. Cook on low for 8-10 hours. Serve over rice or noodles.

What I love most about this recipe is how SIMPLE it is. I always have the ingredients on hand. It’s 4 ingredients total and takes 5 minutes to prepare. It’s the perfect meal for the crockpot when you just want to come home from work and have dinner ready. I decided to make this recipe on Saturday night because it was so easy to do.

I usually spray the inside of the crockpot with PAM just to make it easier to clean. The recipe calls for 2 pounds of meat but I usually just do 1 pound (sometimes even a little less).

I get the beef that’s already cubed for making stews and rinse it, dry it and then drop it into the crockpot.

I mixed the soups together in a bowl but to be honest you can make this recipe even easier and skip that step. In a rush you can totally just pour the cans into the crockpot as is and let them mix together in there.

I sprinkled the onion soup mix package on the meat and then poured the soup mixture on top.

I add a lot of freshly ground black pepper as well. There’s no need to add extra salt because the onion soup mix is pretty salty.

Turn the crockpot on low and let it do it’s magic! I prepped everything after the gym on Saturday and then left the house for most of the day to see my friend Robyn and run errands. By the time I got back to the house 6 hours later the whole smelled warm and inviting with the aromas of crockpot food. YUM.

According to this calorie counter recipe analysis, the recipes is about 331 calories a serving (not including the rice or noodles).

I cooked the rice in my rice cooker. I realized at the last possible moment that I did not have quite enough brown rice so I supplemented with a little bit of whatever rice I could find in our pantry.

We happened to be babysitting our friends’ 6 month old baby Saturday night. I’m glad that I decided to make something easy in the crockpot while we watched the baby for the first time. I don’t think we could have (sanely) made a complicated dinner AND babysat.

The baby (Norah) “helped” me while I made the rice. She was a bit fussy whenever I left the room so she came into the kitchen with me and kept me company while I got the started in the cooker.

The crockpot was basically done. The rice cooked for about 25 minutes and then I started steaming the carrots. When the carrots were cooked I added a little Goddess Dressing to them. I really could have just tossed the carrots into my dish with the rest of dinner but it had been too long since I had some Goddess Dressing.

So Norah was finally sound asleep in the other room and we both had a glass of what little red wine we had left.

Dinner was finally ready! After hours of sitting in the house smelling the dinner cooking….tempting me…taunting me…it was finally ready. I topped the rice with the gravy and the chunks of meat.

It was hearty and felt like comfort food. The meat was so soft it fell apart when I put my fork in it. Perfect dinner!

The original recipe also called for chopped mushrooms but since I don’t like mushrooms I leave it out. I’ve often wondered if I could put chopped carrots into it and whether or not that would add something to the recipe or just ruin it. I haven’t been brave enough to give it a try.

Try this recipe on a weeknight when you know you’ll be too tired to cook. It will be a lifesaver. AND it’s tasty!

  1. Funny – when I was a kid, we ate London Broil all the time, but “London Broil” was a piece of beef filet wrapped in bacon. That was what was on the grocery store package, and we grilled them. I was wondering how you were going to make that in the crockpot! LOL!

    This looks good, though. Perfect winter food. I have a crockpot but rarely use it. My mother would be ashamed of me. 🙂

    1. Now your version of “London Broil” sounds awesome! Bacon! YUM!

      I’ve made this recipe for years. I copied it from some cookbook and I have no idea where I got the recipe. Now I’m curious about the name!

  2. Thank you for a new Crock Pot recipe. I can always use more “go to” crock pot meals as a busy student and mother.

    My “Go to” Crock Pot recipe: BBQ Ribs
    Ribs (1-3lbs, any type you like, I default to boneless – they fall apart)
    Kosher Salt and Freshly Ground Black Pepper
    1 can Coke
    1 bottle bbq sauce
    Put ribs (trim if you prefer, which I do) in crock pot. As you add, salt and pepper according to your tastes. Try to keep seasonings even across the surfaces, as any ribs you lay on top of the ones below will get seasoning on both sides. Add all ribs to crock pot.

    Open can of coke. Pour half of can over ribs. Figure out what to do with the other half of can. 🙂 Put lid on crock pot. Turn to low and leave alone for 6-7 hours.

    After 6-7 hours, empty liquid from crock pot and add bbq sauce to taste.

    Cook 1 more hour on low.


    (Exceptionally good with cheesy potatoes and either broccoli or corn.)

    1. Mmmmm thanks Mer! I saved this one. I will definitely be making it soon. Since Michael and I are both ex-vegetarians we’d rather not eat meat right off a bone so I’d probably do the boneless ribs.

  3. The easiest recipe for the crock pot is to put a whole chicken in, generously cover with your favorite spice blend (cajun seasoning, lemon pepper, Montreal Chicken mix, etc), put about 1 c of water in and cook on low for about 6 hours. The chicken will be falling apart. You can add carrots, onions and other vegetables to make a stew, or you can just cook the chicken alone.

    The London Broil recipe looks great! Hopefully I’ve got a flank steak in the freezer to make this with, since I have all the other ingredients.

    1. I never thought about trying a whole chicken in the crockpot. I have a smaller crockpot so I’m not sure if it would work with mine but maybe a small chicken or a game hen?

  4. This sounds delicious. I will be making this very soon. My go to crockpot recipe involves chicken and salsa. Done. Frozen chicken breasts are covered in salsa. Turn the crock pot on low. Shred the chicken with two forks when you get home after work. We will have it on lettuce for taco salad meat.

  5. Making this for dinner tonight. I did add mushrooms. Had a taste of it and it is yummy! Only thing I would do different next time is add sliced onions and bell peppers. Thanks for the recipe!
