Crockpot Mongolian Beef

 My family loves Asian-inspired food.  We don’t have many takeout places close to where we live, so when I find an easy recipe (especially when it is made in the crock pot), I jump on it.  I knew this recipe would be a hit even before I made it.  It doesn’t require any cooking on preparation day, just throw a few ingredients in a bag, and that’s it!  It smells sooooo good while it’s cooking, and looks like you spent all day slaving over the stove!  By the time the steak was finished cooking, it was fall-apart tender.  This Mongolian Beef has a sweet/salty taste, and both of my kids loved it! I served this over rice and cut up a couple of extra green onions to sprinkle on top.

    What would you suggest as the cooking time FROM frozen? I like this recipe, but it seems a little impractical to have the pot cook for only 5 hours max. Any thoughts?

    • Tricia says:

      We don’t recommend cooking from frozen but I would imagine it would be around 8 hours.

    • Tina says:

      This recipe is awesome!!
      In the crock pot, it only took about 2 hours on high for 1 1/2 lbs of flank steak.
      I actually made another recipe using the sauce recipe (only half of the amount) to make stir fried chicken in my wok. I sliced and dredged the chicken just like you would the beef, I mixed the ingredients to make the sauce in my wok on med-high and then I put the chicken in and cooked on high for about 5 minutes. I mixed in some fresh broccoli, carrots and pea pods that I had pre-steamed in the microwave. Serve over rice, or in lettuce wraps. My family loved it. I don’t care for ginger, so I left that out of both recipes.

  2. Caren says:

    This looks delicious! Just to clarify, you coat the raw meat and then just place it on top of the rest of the (stirred up) ingredients, but don’t stir it all together right?

  3. Stephanie says:

    Making this tonight- on batch to eat, one batch to freeze :-)

  4. April says:

    Hi, would it hurt this to cook it longer?
    My crockpot as set settings (Low – 8 and 10 hours) and High (4 and 6 hours) then moves to warm.
    If I wasn’t home, I’d have to cook it on high 4 hours and it warm a big chunk of the day or cook 8 hours on low.
    Would either work for this and which would be better?

    • heather says:

      No, April, I don’t think it would hurt at all to cook it longer. I’d probably cook it on low for the longer amount of time.

  5. Molly says:

    Can dried ginger be substituted for fresh without it taking too much away from the dish? I dont use fresh ginger and for such a small amount it seems like a waste of $ to go buy it…

    • Tricia says:

      Yes, it can, I have done that on many an occasion.

    • AlysonRR says:

      Molly – I frequently use prepared ginger in a tube from the grocery store. It’s a ginger paste and, in my store, you can find it in the refrigerated part of the produce section. Hope that helps!

    • Julie S says:

      I’ve heard that fresh ginger freezes well. Just use what you need, and freeze the rest for next time.

      • Cherub Mamma says:

        Fresh ginger freezes WONDERFULLY! I simply peel the ginger and wrap it in plastic wrap. I then put the wrapped hunks (as it inevitably breaks during peeling) into a plastic bag in the freezer. When you need to use it there’s no need to thaw. Simply grate the ginger with a fine grater and use just like you would fresh. The flavor is amazing and it’s easy to keep “fresh” ginger on hand all the time. (Besides, fresh ginger is so cheap for the flavor bang you get.)

  6. jason says:

    Does the green onion go into the crock pot or just sprinkled on top when serving? The photo does not look like onions cooked in a slow cooker for 4 hours. Thanks.

    • heather says:

      The green onions are cooked in the crock pot, and I cut up a couple of extra to sprinkle on top for added color and flavor.

  7. Christina says:

    Made this today, it was good, but a little sweet to me. I might try and add some spice and Chinese peppers next time :)

  8. Rachel says:

    Can you make this without a crock pot? You have some great meals here but I don’t have a crock pot and I don’t want to shell out for one

    • heather says:

      Hi Rachel, yes, I think you could make this without a crock pot. I think I’d brown the meat in a Dutch oven, prepare the rest as directed, maybe decreasing the liquid a bit. I’d bring it to a boil and cook it the rest of the way in the oven. It will need to cook a while so that the meat becomes tender.

  9. JudyL says:

    There was a place in my home town that made the best Mongollian Beef! They served it over cellophane noodles, which was really different at the time(1980s).Every other place I’ve tried, the dish was way too hot & spicy for me to eat & the recipes I’ve seen look the same. This looks really good, simple & something my kids would probably even eat. Thanks!

  10. JudyL says:

    Oope, I meant beeF – not watching what I’m doing!

  11. Lizzie says:

    Is this one meal? :) (or something like 4 servings?) looks awesome:)!

  12. Tracy says:

    I made this last weekend and it turned out incredible! My boyfriend and I love PF Chang’s Mongolian Beef, but this is better! It was super easy to make. The only thing I changed is that I used the low sodium soy sauce. We’ve got to watch out salt intake! This will definitely be made again and again and again…

  13. Debi says:

    Is there a cut of beef besides Flank Steak that would work and taste as well? Where I live Flank steak is hard to find and expensive when you do.

  14. Dyana Schroeder says:

    I decided to use chuck steak and chuck roast, as it is less expensive and happened to be on sale when I made this. To get the “poundage” that I needed, I got one small roast and one small steak and just sliced it into small fajita pieces. It was awesome! My husband and kids loved it : )

  15. Genevieve says:

    Can i do this with chicken breasts?

  16. Jenny says:

    I made this last night and it was fantastic! I will definitely be making it again!

  17. ray says:

    I made this for dinner last night and served it with garlic mashed potato. My family really liked it. Husband thought it was too sweet for him so I’ll probably cut back on the sugar next time. Otherwise everyone else enjoyed it including my 22 month old grandaughter.

  18. Erin says:

    I have this in the crock pot now and it smells amazing! Just make sure you don’t overcoat the meat in cornstarch though. My hubby was helping me this morning and I asked him to toss the meat in cornstarch while I did the rest of the prep and he went a little overboard. We have a very gelatinous sauce now. Still tasty, but it doesn’t look so good.

  19. Angie says:

    Made this for dinner last night. Holy sodium, Batman! Next time I’ll use low sodium soy sauce because that’s all that I could taste & the kids refused to eat anymore after the first bite.

    • heather says:

      I’m sorry that was your experience, Angie. I don’t remember it being overly salty, but I always buy low-sodium soy sauce as a rule. I hope you try it again and love it!

      • Angie says:

        I plan on giving it another try because, despite the saltiness, I can tell that it will taste great with low sodium soy. Just wanted to give everyone a heads up who, like me, have regular soy.

  20. april says:

    Sorry…Im a little confused. I want to make this to freeze. so do i cook it in crockpot first then freeze then thaw and cook in crock pot again??? Forgive me…Im a newby.

  21. Tena says:

    We make this weekly .

  22. Amy says:

    made this tonight – big hit! I added some sliced red peppers in addition to the carrots – served over brown rice & broccoli. I might add some siracha or red pepper flakes next time, thought it needed a kick, but delicious as is!

  23. Cindy says:

    Thanks for posting this, we made it tonight. YUM! But next time i may add some red pepper and less brown sugar, only because we prefer more spice than sweet! Thanks again :)

  26. Lynn says:

    This was WONDERFUL!! I only had 5 ounces of soy sauce, so I did the same amount of water. I added some thinly-sliced sweet red pepper during the last hour of cooking and it was wonderful. I will be adding this to our rotation!!

  27. Sandi says:

    This is a staple in my freezer. I make a new patch every couple months and my family never tires of it. Thanks for the share!

  28. [...] Mongolian Beef Meg’s tip: This dish has a lot of potential, the sauce was delicious but I suggest cooking for half the time suggested. We cooked it on low for about ⅔ of the time stated in recipe and it was so overcooked we couldn’t eat the meat. The short cooking time kind of defeats the purpose of preparing for the freezer and slow cooking so we probably won’t repeat this recipe. We served this with rice. [...]

  29. Lauri says:

    Just to clarify, the 1/4 cornstarch is only for tossing the beef? Or is it 1/4 c cornstarch in the sauce (and as required to coat the beef)?

  30. [...] {recipe adapted from OAMC} [...]

  31. Melissa says:

    Delicious and so easy to prepare!! The only change I made was to cut the sugar back from 3/4 cup to 1/4 cup because 3/4 seemed excessive for a recipe that only has four servings. Next time I will probably add more carrots and maybe some sliced red pepper as some previous posters suggested.

  32. Gayle says:

    It was FANTASTIC!!

  33. Gayle says:

    It was FANTASTIC!!! Made half the recipe, added a little Hoisin Sauce then froze immediately. When I jotted down the cooking time on the freezer Ziploc bag, I forgot to reduce the time by half. Oops. Although the meat was a little overcooked, it was devoured within minutes. Definitely will make again, though next time I’ll add some julienne carrots, red pepper strips and broccoli florets during the last hour or so.

    This is in your gluten free menu but doesn’t soy sauce have gluten?

  37. Clare says:

    Great flavor and consistency. But waaaay too salty. Next time I will use reduced sodium soy.

  39. Debbie says:

    Trying this tomorrow for dinner. It looks so good. Can’t wait I will let you know the outcome. So far I have tried lots of your recipes they were all great and my husband said they were keepers. Thank you thank you.

  40. Debbie says:

    This was just awesome. I used egg noodle instead of rice. It was perfect. Will make it again and again.

  41. Debbie says:

    Keep the recipes coming Lisa.

  42. jen says:

    Good food. :) I made one for tonight and one to freeze. The one I made today I put too much cornstarch on the beef…my bad. No one noticed except me. I used my usual low-sodium soy sauce so the seasoning was appropriate. Cooking time on low could easily be reduced an hour… Enjoy!

  43. Daniel M says:

    Just made this tonight; super easy, so much flavor! Roommates had already eaten out but just had to dig in once they smelled the deliciousness. So going into the keeper list. Thanks so much!

  44. kaye says:

    this dish is amazing! we add more shredded carrots than what is called for and also add broccoli to the mix to round out the meal. definitely a meal the whole family enjoyed and asked for more!

  45. Daksha says:

    Could I use stewing beef chunks instead?

    • Lisa says:

      You certainly could. You may need to cut into smaller chunks or increase cooking time. Let us know how it turns out!

  46. Sara says:

    I added fresh brocolli when I started it… it came out perfect, so no need to dirty an additional dish. Next time (because according to my husband there will DEFINATELY be a next time) I think I’ll add peppers and brocolli (I had planned to add peppers the first time but forgot to start the crockpot that morning so it became just steak and peppers stirfry lol

  47. Sharon Quinn says:

    I am going to try this but rather than freezing, I intend to can it. .Plan to add extra green onions before serving, maybe green pepper slices too. Will try with beef and chicken. Wonder if pork would be good. I understand that your focus is freezer but I love canning. And many of your recipes sound like I can can as well as freeze. Obviously not canning the rice. Have you ever canned any of your recipes?

    • Lisa says:

      Sharon – please let us know how it turns out canning it. I have never canned a meal like this before, so I am certainly curious.

  48. Terry says:

    I made the Mongolian Beef exactly as you wrote it. I even shook off the extra corn starch from the beef. This meal was not very good. It was gummy and worse than that, it was tasteless. Sorry, not for me or my family. We threw the entire meal out asap.
