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?

Has anyone made this in an Instant Pot instead of a crockpot? If so, how long did you cook it for??
carmen l says
getting ready to make this today, do you think I can use potato starch instead of cornstarch? Thanks!
Sara says
I haven’t tried it that way so I’m not sure if it will work, my guess is that it would be ok!
Beth says
Could Top Sirloin be used instead of flank steak? Looking forward to making this.
Sara says
Yes that should be fine!
Madison Barnette says
It seems like the meat is following apart- do you advise against stirring it periodically? I’m wondering if that’s what I did wrong.
Sara says
You should not open a crock pot while the food is cooking as the temperature will be lowered considerably each time it’s opened and the food may cook unevenly!
Tricia says
Is it ok if I use olive oil instead of the sesame oil?
Sara says
I would omit it, olive oil won’t give you a similar flavor.
Mary says
Absolutely fabulous recipe Served over cauliflower rice so delicious If you like garlic don’t be afraid to a bit more.So easy
Steve says
This was perfect as is. I am making it for the 2nd time tonight. Any preference to the High or Low cooking temp in the crock pot? I did High last time bit will try Low tonight. That green pepper and onion suggestion sounds good – but I’m afraid to mess with perfection.
Sara says
I typically use low heat as I think the meat comes out more tender!
David Ormandy says
This looks great. my mouth is watering az can,t wait to try this on long grain rice
Kristy says
Hi Sara, I just wanted to say a big THANK YOU for sharing this recipe – I love Chinese food, but my husband usually does not. He loved this though! We just finished eating my first attempt at cooking it, served with steamed greens and homemade fried rice. There were groans of yum and clean bowls all round! My husband has just reappeared with a second helping. This was so easy and very, very tasty. Thanks again for sharing 😊
Maureen O'Connor says
Delicious! So surprised that it tasted as good as it did for being so easy to make! Now following you on Facebook. Thank you so much!
Melinda says
This is my second time making this. We love this. I followed the recipe as the directions read, however this time I added sliced green peppers and onions. It’s in my crockpot right now 🍽🍽
Candy Ambrose says
Getting ready to make this today, would you add the green peppers and onion in the slow cooker in the beginning or towards the end? TIA
Sara says
You can add the onion at the beginning, I’d wait until the last 2 hours for the peppers!
