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?

Slow Cooker Mongolian Beef Recipe


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.

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!

Calories: 330 kcal
  • 1 1/2 lbs thinly sliced flank steak (1/4 inch thick)
  • 1/4 cup cornstarch
  • 1 Tbsp vegetable oil
  • 3-4 cloves garlic, minced
  • 2 tsp fresh ginger, minced
  • 3/4 cup water
  • 3/4 cup reduced sodium soy sauce
  • 3/4 cup light brown sugar, packed
  • 1 - 2 tsp Sriracha sauce (can substitute with red pepper flakes or cayenne instead - in whatever amount you prefer)
  • 1 cup shredded carrots
  • 4-6 green onions, thinly sliced
  • sesame seeds, for garnish
  1. Add sliced flank steak and cornstarch to a large resealable plastic bag.  Close and shake to coat well.  This can be done in a large mixing bowl as well, but I find it's less messy to do in a bag.

  2. To the bottom of slow cooker, add vegetable oil, garlic, ginger, water, soy sauce, brown sugar and Sriracha sauce.  Stir to combine.

  3. Add in coated flank steak and carrots and stir again until everything is coated in the sauce.

  4. Cover and cook on HIGH for 2-3 hours or on LOW for about 4 hours, until steak is cooked and tender.

  5. Serve over white rice and garnished with green onions and sesame seeds if desired.

  1. Anyone ever marinated the meat overnight? Thinking of prepping it and refrigerating it for a day or two. First time making the recipe 

  2. This recipe is fabulous! I normally hate using the slow cooker because everything comes out so bland but you nailed it with this one! 4 hours on low is perfect and the meat was so good! I’m putting this into my regular recipe rotation for busy nights!

  3. Can I use a chuck roast?

  4. My husband and 4 kids loved this tonight! Do you have any idea how hard it is to find a recipe that my entire family enjoys?! It was magical… thank you so much for a whine free evening. 😀 This will absolutely be in my rotation from now on.

  5. Thx for sharing this – so easy 😀😀 I got tired of waiting around 1 hour into slow cook. Thank goodness for instant pot!! Switched over to pressure cook setting high for 30 min and it came out perfectly. Prob would lessen sugar next time and add more heat. Also not sure if the cornstarch is necessary for the instant pot version so will try without it next time. 

  6. AWESOME!!
    I added leeks and red pepper slices and reduced sugar to 1/2 cup!!! Used simple stir fry steak already sliced!!!
    This will be made over and over!!! Yeah!!! Thanks!

  7. Thanks Amanda, I used a lower grade of supermarket “chopped steak”, substituted cut green beans instead of carrots, and used dried red pepper flakes as you suggested. Otherwise the same preparation process and other ingredients. Green beans were added at the 3-hour point on your Slow Cooker (low heat) 4-hour cook time. Served with steamed Broccoli over properly prepared (twice rinsed Nishiki brand) white rice. Excellent rendition!

  8. Loved it. Made for large family so doubled it up. Came out great just doubling everything. I did add one thinly sliced onion and some broccoli as well in the end for about an hour. Probably reduce sugar a bit next time for me, but everyone else loved the sweetness level.

  9. Hi! Can this be put together the day before ?

    • Hi Marlene 🙂 I wouldn’t recommend putting the whole thing together, since the cornstarch will start “working” as soon as it’s combined. But you could absolutely slice the beef and make the sauce ahead of time and just keep them separately refrigerated. It would cut down on prep time considerably!

  10. Can this be slow cooked in the oven as my slow cooker is not working?

  11. I just want to say how incredible this is!! In all my life I’ve never been able to replicate a dish from the Chinese down the road… until now! Amazing! Thanks

  12. Very cool that you added tips and tricks to the recipe instructions! Very helpful to low skill cooks like me! 

  13. OMG SOOOOOOOO good thank you for sharing.

  14. Is there any reason not to just mix the cornstarch with the sauce ingredients, rather than coating the meat with it, since it all gets stirred together?

  15. Followed receipe…too sweet! Next time I will cut the sugar😁 I will try it again but will tweek the receipe. Is this suppose to be sweet?

  16. Hi,
    If I double, or even triple this recipe, will the cooking time be more or less the same? And it would just be yummier re-heated wouldn’t it….. 🙂

    • Hi Hege 🙂 I’ve never doubled or tripled the recipe, but I would assume the cooking time would be about the same, maybe a little bit longer. And yes, reheated leftovers taste great!

  17. Can you add broccoli to the Mongolian beef made in slow cooker

  18. Thanks for specifics on how to slice the beef, its’ like youre right there in my kitchen!

  19. Delicious and so easy to prepare!

  20. Have you tried to add frozen broccoli or tried this with chicken?

  21. How many calories are in this recipe? And or calories per cup?

    • Hi there 🙂 I don’t provide full nutritional information for my recipes, as I’m not a nutritionist and don’t want to inadvertently pass out incorrect information. My advice would be to plus the ingredients into whichever online nutrition calculator tool you typically use. myfitnesspal.com is a popular one.

  22. Can you use skirt steak instead of flank steak?

  23. Can you please tell me what the small black things are in the picture. I cannot see anything of the ingredients that would have that in it

  24. Made this for the family tonight and it was voted a KEEPER! I served it in a large pasta bowl – layer of rice, layer of steamed broccoli and the Mongolian Beef. OMG! We will be making this again soon.

  25. We had this tonight and it was delicious! We added some steamed broccoli in about 10 minutes before we ate it. Perfect amount of spicy and sweet and so easy to make!

  26. REALLY GOOD and really easy! (I used powdered ginger- just as delicious!)

  27. This looks really good! Looks like a new family favorite!

  28. I’m totally trying this. Thanks for another amazing recipe!!

  29. I love a slow cooker beef recipe that doesn’t have to be seared before hand! This looks amazing – I know my boys will love it!

  30. This slow cooker dish is the best! I have got to make it soon!

  32. This is making me hungry! Looks perfect for dinner any night!
