This Slow Cooker Mongolian Beef is so quick and easy — throw everything in the crockpot and let it cook! Tender strips of steak, covered in a rich, dark sauce full of Asian flavours with a touch of sweetness.
I know sometimes it seems like a tragedy to put steak in the slow cooker.
When I sent my husband grocery shopping for this dish, I requested sirloin steak — a nice, lean, middle of the line steak. He purchased striploin steak — an incredible, but pricey, cut of steak we reserve only for the grill.
The crockpot does such an amazing job at tenderizing less expensive cuts of meat, there is really no need to go all out here!
Just throw everything in and let it cook away for a good part of the day and know that dinner is taken care of.
This Slow Cooker Mongolian Beef has a rich, dark sauce — not too sour or too spicy, compared to the Honey Balsamic Pulled Pork or the Sweet & Spicy Coconut Grilled Chicken. The flavours are a lot more subtle in this dish, and it goes perfectly over rice or noodles.
I love using my slow cooker for supper when I’m going to be home all day. Maybe that sounds weird to you, as it’s such a great appliance to use when you’re going to be gone all day. But sometimes I just love having a full day to “relax” (like that ever happens) and not even having to make supper when 5:00 rolls around. It’s about as good as a staycation gets for us these days.
So I put this in the slow cooker day on a rainy Monday off from work and spent a lazy afternoon on the couch — it was the perfect end to a long weekend!
The recipe makes a good amount of sauce. We like a lot of sauce, perfect for spooning over whatever else is on your plate!
How to Make Slow Cooker Mongolian Beef
- I have made this recipe and browned the beef first in a frying pan before adding it to the slow cooker. It’s an extra step that isn’t necessary, but the steak will hold in the juices instead of diluting the sauce.
- If you don’t like your peppers and onions soft, feel free to just toss them in for the last hour — I put mine in for the whole cooking time. Once again, laziness. Do whatever works for you, and whatever your family prefers.
- If you like things spicy, feel free to add in a pinch of red pepper flakes when you’re stirring up the sauce!

Maria says
What size slow cooker did you use? I have a 7 quart and find that it’s often too big for many recipes, drying out the meat due to not being full enough and delivering too much heat
Ashley says
I have a 6 quart and find that happens often too! When I know I need to leave something in all day, I often put the meat in frozen so that it doesn’t get overcooked. Otherwise I set it for a lower time and let it go to Keep Warm.
Dan says
I love this served over pasta instead of rice- I would have never thought of that! Sounds amazing.
Ashley says
Thanks Dan! It would be great over rice as well!
Jason says
Making this right now, waiting patiently until it is finished! We love our slow cook meals when we’re all busy with work and school here at home. Looking forward for the finished product, smells delicious already.
Ashley says
Thanks Jason! I hope you like it!
Brooke says
I made this tonight and I don’t know what went wrong. I followed the recipe exactly. The sauce never thickened up and in the end all you could taste was cornstarch.
Ashley says
I’m sorry to hear that! Maybe your beef let out a lot if juices that diluted the sauce? Next time you could try the browning first — it helps seal in the beef juices. Hope that helps!
Anne says
I work at home and the crock pot is a life saver! I’ve found in the last few years that you really can’t leave a recipe cooking all day because newer crock pots cook at higher temperatures, even on low, so that chicken dishes take only about 2-3 hours to cook and pot roast is done in no more than 5-6 hours tops. I’m really looking forward to trying the Mongolian Beef!
Ashley says
Thanks Anne! It was a big adjustment when my old one broke and I got a new one. My new one actually cooks at a lower temperature, but my previous one was still pretty new.
Lee willie says
This sounds pretty nice, would this work with bone in chicken thighs, browned first?
Ashley says
I think that would work very well! The sauce would add great flavour. I’m just not sure on the cooking time, with bone-in thighs, you might want to cook it a little longer.
Kathy says
So…has anybody tried adding other vegetables to this dish? Broccoli or baby carrots?
Just curious….
Ashley says
I’m sure both would be great, though I’m not sure about cooking time. The carrots might require more cooking time than the beef, and I’m not sure about the broccoli. It’s worth a shot!
Michelle says
Hi Ashley,
This really looks great and I will make it. Although I do have a question, you say in the recipe: Combine the soy sauce through apricot jam in a medium bowl. Pour into the slow cooker, but when do you add in the Hoisin sauce, the garlic and the ginger and also when do you put in the 1 cup of water? Maybe I didn’t read it good, but it is not mentioned anywhere.
Ashley says
Hi Michelle, when I refer to combining the soy sauce through apricot jam, I mean to combine those 2 ingredients and everything in between. Hope that helps! Let me know how you like it 🙂
Michelle says
Thanks Ashley for replying so fast, I understand now so I will be making it this week. I am sure it will taste even better then it looks, and believe me it looks very good.
Ashley says
Thanks Michelle! Hope you like it!

Susan says
Sounds delicious, looks foolproof, I’m in! Does it matter whether I use light or dark soy sauce? I have both but wondered which you used?
Ashley says
I am not a huge lover of soy sauce (I find it can be so salty!) so I would use light. But if you really like the flavour you could use the dark.

Oh my!! This just looks fantastic!! I am sure the combo of jam and hoisin is just wonderful. Plus, I imagine the meat gets so tender in the slow cooker. I am making this soon!! Pinning.

marcie@flavorthemoments says
This looks incredible! I’m pinning this to try. 🙂
Ashley says
Thanks Marcie! Let me know what you think!
Jess @ On Sugar Mountain says
Ashley this looks like an amazing meal! It’s been over 90 degrees here in NJ and I can definitely see myself throwing this together in the crock pot to enjoy later on a hot summer day. As if I need any other excuse to eat mongolian beef other than it being utterly delicious, though. 😉
Ashley says
Lol. Slow cookers are incredible machines! They are perfect in all seasons, but we don’t have AC so it’s definitely a must in the summer!
Annie @Maebells says
This looks fantastic! I am a big crock pot fan too! I am adding this to my “to try” list!
Ashley says
Thanks Annie! Let me know how you like it!
Krista @ Joyful Healthy Eats says
OH my goodness I can smell it already! I was just making a shopping list for the week… this dish is so on it. We love Mongolian Beef.. but in the crock pot? I think I’m in love! Pinned!

Thanks Krista! Everything Crockpot is a win in my books!
