Slow Cooker Mongolian Beef

We absolutely LOVED this dish- the meat was so tender that it just fell apart when we ate it. It tasted amazing!  My husband couldn’t believe that I made this in a slow cooker!

  1. Made this last night exactly according to recipe. It was fantastic. My son and husband can't wait to have it again. The sauce was just slightly thin, so I grabbed a ladle, put some sauce in a pot on the stove, stirring constantly, and it thickened up in seconds. After serving, sprinkled La Choy (crunchy) Chow Mein noodles on top. OMG!

    Question do you have cookbook published yet? If you do where can you get one? I have made lots of meals from off your site and we love them. Although the cookbook does sound grand I love that online you can see the photos of the meals you are making. Making the Mongolian beef tonight...just got done putting it in the crock pot. Thanks for the time you spend sharing with us all.
    • When you go to you will see our cookbook at the will say "check out our book". If you click on that it will take you to amazon where you can order it or read more about it. We will have a 2nd cookbook coming out in February.

    Added 5 carrots (1/3rd inch thick coins) and 1 large onion (sliced eighths) to the crockpot first. Then I put in all the other ingredients (except the shredded carrot). I used chuck steaks instead of flank and sliced the large globs of fat off it. It cooked during our 3-hour Church block. Turned out nicely; all the family liked it.

    Holy smokes! Lip smackin' good! I added a splash of sesame oil, used low sodium beef broth in place of the water, then added some chopped fresh broccoli during the last 30 mins of cooking. Served it up over some fresh brown rice! Yum and YUM! Had the plan to make it into a freezer meal to add to my son & DIL's stash in prep for the new (first) grand baby coming soon. Looks like I'll have to make another batch because the hubby and I aren't letting loose of this one! haha
  5. Mongolian beef is my husband's favorite Chinese dish. Tried to make it a few times but it never came out the same. Came across your recipe yesterday, it was so easy a simple. Oh my god! it was wonderful. My husband loved it. Thank you for sharing.

    This sounds amazing! I found a link to your recipe from a site about freezer meals. If I were to make this ahead of time and freeze it, would I just place everything in a freezer bag, then throw in the crock-pot when ready to cook? I'm new to freezer and crock-pot cooking so thanks for the help!
  7. So exited to make this today! Quick question that hope someone sees :) Do you recommend cooking on high for shorter period of time or low for longer? I'm not usually the steak cooker in the house and I want to make sure it doesn't over-cook. :) Thank you!!!

    I have this in my slow cooker now! It's dinner tonight.....I can't express how good it smells in my house right now. Everyone is chomping at the bit ready eat! I kinda dipped a little shot glass into the "juice" a few minutes ago for a tiny sample...BOY OH BOY IS IT DELICIOUS! I'm super excited, as I do believe this recipe may actually make it seem s though I know how to cook! Thanks for this (and other) recipes. I will update you as to the family reaction after dinner. I was going to wait to post this much, but I was too excited!
