The easiest way you can make a Mongolian beef recipe! The beef gets meltingly tender in the slow cooker and the sauce becomes incredibly silky, with great spicy/sweet flavors!

All of the amazing spicy/sweet flavors of Mongolian beef, but in an incredibly easy slow cooker meal with just 10 minutes of prep. This is the Mongolian beef recipe for the busiest of people!

Who here loves Chinese take-out style meals? *raises hand frantically* I love all the bold flavors, great sauces, and how quickly things cook! One thing I don’t like though, is how hectic it can be to cook take-out style meals at home. The nature of a stir fry is that things cook really quickly, which means you have to have every component in the recipe ready to go… and things can STILL get stressful right?

The main thing I love so much about this Mongolian beef recipe is that unlike some slow cooker meals, it’s made entirely in the slow cooker, with no extra steps to take. No browning the meat, no broiling… just adding all the ingredients, turning on the slow cooker and walking away. Simply amazing.

And this meal is certainly not short on flavor! The garlic and ginger bring plenty of classic Mongolian beef flavor, and combined with sweet/heat combination of brown sugar and Sriracha sauce… it’s a powerhouse of amazing flavors!


Typically Mongolian beef is made with soy sauce, brown sugar, ginger, and garlic. I like mine to be a little sweet and spicy, so I add some Sriracha to it as well.


Most recipes, including both this slow cooker version and my classic recipe, use flank steak. I’ve also heard of people using sirloin steak as well.


  • Slice your flank steak against the grain. As you’re looking at the beef, you’ll see lines, like the grain on a piece of wood. You want to slice it across those lines, not alongside them. Doing this ensures an incredibly tender piece of beef.
  • The carrots are optional, but add a great texture!
  • Add the Sriracha to your tastes. I like this recipe to have a little heat to balance out the sweetness.
  • To make this a complete meal, add some steamed broccoli and rice!

My original classic Mongolian beef recipe has done so well, with so many of you emailing with rave reviews, so I knew I didn’t want to deviate from those flavors. To adapt the sauce to work well in a slow cooker I added some extra soy sauce and water. Also, since there’s no marinating with this recipe, I added some extra ginger and Sriracha to boost the flavors.

    Very easy recipe. I used frozen steak and increased the time of cooking. > have adjusted the spice to what I can tolerate and it was delicious. I also served with sprouts which added some good flavor.


  2. Melanie Rowley says

    I love this recipe, but can I change the beef to lamb? Many thanks


    • The Chunky Chef says

      I haven’t tested this recipe using lamb, so I can’t say for certain whether any changes would need to be made. If you do some experimenting, I’d love to know how it turns out 🙂


    • The Chunky Chef says

      Yes, that should work well 🙂


  3. Anne MacDougall says

    Loved this!! So easy and has lots of flavor. My family loved it!!


  4. Renee says

    Always a hit! Delicious and easy to put together.


  5. Amanda Quill says

    Loved it but found it a bit too sweet so will just use a little less brown sugar next time.
    Any desert idea to go with this please?
    Nothing too heavy!


    • The Chunky Chef says

      Glad you enjoyed! Desserts are a personal thing, so feel free to peruse my dessert recipe index and see what sounds good and light to you 🙂 https://www.thechunkychef.com/dessert/


  6. ginger says

    This was amazing! I put the ingredients in the crockpot at lunchtime. Set to low, phenomenal fork-tender beef with great flavors for dinner. Thanks for posting!


  7. Jason says

    I used this recipe as a base recipe and added frozen stir fry veggies, baby corn, water chestnuts, and doubled up on the sauce. We made a couple crockpots for a school concession stand for my daughters volleyball team and it was gone quick! The second time we made it for concessions we had to hide some for the refs. Really good meal!


    • Erica says

      I love your idea of adding frozen stir fry veggies and water chestnuts to the mix. Did you put the veggies in right away or did you thaw them and put them in for the last hour or so of cooking? Thanks!


  8. Sandra says

    I am a bit disappointed that my question was ignored and disappeared (it was a nice simple question )
    well succes The Chunky Chef


    • The Chunky Chef says

      My apologies Sandra, I didn’t see any previous comment from you? I get about 75 comments per day, and it’s just me running this website, so it may very well have just fallen through the cracks. I’m happy to answer any question you have, either here, or via email (amanda @ thechunkychef.com)


  9. Samantha E says

    If I needed to double this recipe to feed more people can you tell me if I would have to double everything including the ginger and garlic etc or would that be too much?


    • The Chunky Chef says

      Yes, when doubling a recipe you have to double every ingredient, otherwise all the proportions and flavor profiles will be off.


  10. Pam says

    We would have loved this, but way to sweet for us. I absolutely will make again, but cut brown sugar down.


  11. Sue says

    3 fussy men to feed…swapped the beef for quorn steak strips, added red pepper strips and mangetout, cut my carrots into thin strips, only used 1 tsp of Sriracha sauce…turned out amazing, so tasty, 4 clean plates, definitely be doing again thank you


  12. hjdubs says

    This is absolutely one of my faves. Easy to make and my family devours. My only suggestion is to double.


  13. Niamh says

    Hi, my beef tends to be a little tough . I think I’m following recipe correctly and cooking it on high for 2 hours . What can I do to solve ?


    • The Chunky Chef says

      You could try cooking on low, and make sure you’re slicing the flank steak against the grain as mentioned in the post 🙂


      • Stacy says

        You should mention that tip in the recipe. Many folks don’t realize that. I am making this ASAP. Sounds delicious 😋


        • The Chunky Chef says

          Typically I don’t mention all the extra tips and information in the recipe, since then all that will print when people print the recipe, and I get quite a bit of flack about it. But since it’s just one tip, I’ve gone ahead and added it to the “chef tips” section of the recipe.


  14. Linda says

    Looks delicious! Am making a shopping list to make it for friends.


    • Sarah says

      Made it for dinner tonight! Tastes great!!
