Slow cooker mongolian beef with thinly sliced flank steak cooked with soy sauce, brown sugar, garlic and ginger.

Making meals like this slow cooker Mongolian beef, in the crock pot is one of my favorite things to do. Not only does it allow you to have a nice meal when you’re finished with your day but, it feels like you’re getting to skip all the cooking. It kind of feel like cheating because it makes dinner time that much simpler!

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?

Mongolian beef was created in Taiwan where dishes like this slow cooker Mongolian beef were popular. That area was where the first Mongolian restaurants started opening up. They made the Mongolian style of food popular which is why the name is carried with dishes like this one.

Looking for Mongolian beef but don’t have the time to wait for it to cook in a crock pot? Try my stove top version!

One thing I’ve learned over the years is that it doesn’t take a ton of work to have a delicious meal. I love this crock pot Mongolian beef because it’s easy, but comes out totally delicious and satisfying. Even my kids love this one!

      Best Mongolian Beef recipe I have found. I used sirloin which I hand sliced (freeze meat for 30 minutes is a great tip and one I have used for years) and doubled the sauce- fantastic! Served with fresh steamed broccoli and jasmine rice. The extra sauce is perfect to customize servings – each person can add rice, broccoli, and sauce as they prefer. Great meal for guests or a party. Like ideas from others to add bamboo shoots and mushrooms for additional items to customize. Thank you for the recipe.

      Tip on jasmine rice – soak in cold water for 30 minutes, rinse until water is clear. Cook on stove until desired tenderness. Jasmine rice is perfect for this recipe as it is long, thin, not “starchy”, and has a mild taste that can be enhanced depending on what you are making. Perfect for this recipe with the sauce and meat on top or mixed in.

        Great recipe. Some tweaks depending on style I did were some spicey heat to it. I seared the steak so it had some texture and mushrooms were good add. Have a great day!

      Hi, this seems delicious and I’m planning to cook this for dinner tomorrow. If I use regular soy sauce instead, should I reduce the amount? How much should I put? Thank you!

      Amazing recipe! Simple but so delicious! I use Wagyu stir fry meat so it’s already cut up which makes it that much easier! When I ask my husband what he wants for dinner for the next week, he always says this Mongolian beef! Thanks for the recipe!

      If I use a little over 2lbs of flank steak, would I need to increase the amount of cornstarch at all or still just use the 1/4 cup?
      Thank you!

      This is a very easy dish. I used finely sliced brisket (1cm thick) because no other slow cooking steak was available. We thought that it needed more ‘oomph’ so doubled up on the sauce ingredients and added some sweet chilli . To keep carbs down, used shredded stir fried cabbage and broccoli. Will make again. Thank you.

        Yes but you’ll want to increase the cooking time and maybe add some more liquid because the stew meat will take longer.

      I made it last night and it was so good. I had leftovers and went to have them for dinner. It did not reheat well in the microwave. Any suggestions for reheating?

      • Sara says

        February 22, 2022 at 8:00 am

        You could reheat in the microwave in 30 second increments so that the meat is warm but not overcooked, or put in a pan on the stove on low heat just until warmed through.

        Add a couple tablespoons of water to the dish before you reheat, whether you use the micro or stovetop.

        I’m not sure if it would work this way, partially freeze the meat for about 20-30 minutes and it will be a lot easier to slice!
