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.

Hi Sara. What would you recommend adding to give it a little spiciness?
You could add some sriracha or crushed red pepper flakes!
Hello, could i use my strip steak?

I use light brown sugar!
I have some stew meat. Do you think this recipe will work with stew meat? If so, how long should I cook it in the crockpot? Thanks.
I’d slice it thinly and add an extra hour to the cooking time!

The Mongolian beef was the first recipe on your site that I tried. The whole family loved it. I had two pounds of flank so made one and a half of the sauce (except for the soya sauce) It was perfect. Took a total of three hours on low and came out soooo tender.
I want to double the recipe and use 3 pounds of meat. Should I double all the ingredients in sauce? What do you recommend?
Can’t wait to try more of your recipes. Thanks Sarah!
You can double everything except the soy sauce. I’d use 1.5 times the amount of soy sauce!
Thanks Sara! Sorry about spelling your name incorrectly the first time. I really appreciate your quick response.
Just made this recipe and it came out great!
Just a small Q: how would you adapt this for using chicken or pork instead of beef?
You could use thinly sliced chicken breast or pork tenderloin and cook for one hour less!
How do I adapt this recipe to cook in an instant pot?
Unfortunately I do not have an instant pot version of this recipe!
Will this work with a skirt steak?
That should be fine!
Can you use Chuck steak instead of flank steak to have a chunkier dish?
Yes but it will take longer to cook!
I used a skirt steak and sliced it against the grain, which was my mistake because it fell apart into tiny little chunks after 4 hrs on low. Tasted awesome though, and I’m looking forward to trying it again with a sliced flank steak as was written in the recipe lol, thank you!
I threw in a radial cut onion, red pepper flakes and some Sriracha. Doubled the garlic and ginger. I also cooked a bunch of Shitake mushrooms in butter and white wine and threw those in at the end. I served with steam broccoli and rice. Y’all it was GREAT!
I am excited to find a recipe for pineapple chicken. I am going to make it over the weekend.
I use a London Broil. Works great! Tastes and smells Awesome
