Making meals like this slow cooker Mongolian beef, in the crock pot is one of my favorite things to do. Not only does it allow you to have a nice meal when you’re finished with your day but, it feels like you’re getting to skip all the cooking. It kind of feel like cheating because it makes dinner time that much simpler!

HOW DO YOU MAKE SLOW COOKER MONGOLIAN BEEF?

This Mongolian beef has the rich flavors of ginger, garlic, and brown sugar. It’s cooked slowly in the crock pot so every flavor has a chance to really sink in. When it’s almost ready to be served, the green onions get added to the pot and stirred in. The family is sure to love this one.

I highly suggest slightly freezing the flank steak before slicing it. It makes it much easier to slice if you do so. I prefer using the low sodium soy sauce because it keeps the dish a little healthier and you won’t have to worry about the finished dish being overly salty.

This crock pot Mongolian beef pairs well with steamed rice. I always serve it with a green vegetable on the side such as broccoli or asparagus. Of course, there are many other sides that would work as well, but I love the fresh counterpart of a lightly steamed veggie.

ARE THERE SUBSTITUTES FOR FLANK STEAK?

Yes, there are a few other options that will work for this crock pot Mongolian beef. Flank steak is my favorite option but you can also use skirt steak or even hanger steak if you can get your hands on it. You could also use thinly sliced sirloin steak if desired.

WHY IS IT CALLED MONGOLIAN BEEF?

Mongolian beef was created in Taiwan where dishes like this slow cooker Mongolian beef were popular. That area was where the first Mongolian restaurants started opening up. They made the Mongolian style of food popular which is why the name is carried with dishes like this one.

  1. I made fpr 3rd time cooked on high 2 hours was perfect all the time. First time was 2.5 lbs so took little longer the other 2 was 1.5 and after 2 hours was perfect on high!

  2. Made this tonight, left it on low in the crockpot for 4 1/2 hours, 4 hours would have been plenty. My husband said it was delicious and it was, just the sauce was a little strong, not sure if it was too sweet or too salty, but all in all was very good. Will make it again. Served it with with quinoa, broccolini and stir fry vegetables. Sticky white rice would have been good but quinoas is delicious and so much healthier.

  3. After 6 hours on low, the meat was very tender but almost disintegrating. And to answer the person who asked if it could be made with chicken, I tried it and did not like either the texture or the flavour – stick to beef and the taste is wonderful.

  4. I want to make this recipe, it doesn’t say to brown the meat before placing in crock pot, wouldn’t it be better if it was browned first?

  5. Sometimes when I double a receipe, it seems to be too much for my 6 quart cook pot? Can I double this recipe and only use one crock pot? Do I need to leave in longer if I double the receipe? Thanks for your help.

  6. I doubled the recipe. Pretty strong sesame smell. Is that normal? Also used light brown sugar on hand so it looks a lighter. Will it cook down?

    1. It sounds like you did just fine, the sauce will thicken as it cooks from the cornstarch on the meat!

  7. Hi I live in Australia and have tried buying flank steak but it doesn’t exist here. What could I use instead?

  8. I’m watching my sodium, do you think I could use a 1/4c sodium soy sauce instead? Would I need to make up the difference with water? My first batch is in the cooker as I write this but I already thinking ahead! I usually make recipes as written the first time round.🙃

    1. I think you should be just find using 1/4 cup without any added water! The meat will also release liquid as it cooks.

    Made this last night for dinner and it was very good with minimum effort. I used a cheaper cut of meat, top round and cooked for 6-7 hours. I added some chili flakes. Will be making it again soon. Thank you.

    1. You could add carrots, mushrooms, zucchini or broccoli during the last hour or two of the cooking time. You do not need to alter the liquid!

      1. 5 stars
        I added carrots, but didn’t like it as much. Didn’t think about mushrooms, but that sounds yummy!

    Question please.

    I used deer meat and it tastes great but the sauce is more like a thick gravy.
    Is that due to to much cornstarch or that the deer meat doesn’t have any fat?? Thanks.

    1. Are you saying the sauce was too thick or too thin? I actually haven’t ever had deer meat so it’s hard for me to say!

    2. I would think it’s because venison doesn’t have as much fat and is very dense with less juices. I was looking at it for venison and will thin this s sauce with a little water. Glad i read the comments!

  11. 5 stars
    Brilliant. Took me a few minutes to convert cups into ‘rest of the world’ measurements, and might try adding a cinnamon stick next time, too. Mongolian Christmas flavours? Cheers, Marc PS served with Thai Jasmine sticky rice – which was perfect to soak up the unctuous sauce.

  12. 4 stars
    I just made this and it was tasty. I used 1 1/2 lbs of flank steak and the corn starch was too much. I’ll make it again with less corn starch and maybe a little less water because it was very saucy.

  13. After tossing the beef in cornstarch there will be some cornstarch left in the bowl.
    Dies that get added to the pot also?

  14. If I need to have this in the crockpot for more than the stated cooking time, would I just add more water so the liquid doesn’t all cook off and burn? Or would I just need to have someone turn it down to the “keep warm” setting until we’re ready?
