How do you make Slow Cooker Mongolian Beef

This easy family recipe could not be simpler to make! It only requires a few minutes of work (most of which you can do ahead of time), and a few simple ingredients!


  1. Thinly slice your beef into strips and toss with cornstarch to coat.
  2. Place the beef slices in the slow cooker with your slided onion and peppers. The onions and peppers can be sliced ahead of time and stored in a glass airtight container in the fridge for up to 1 day.
  3. Mix up the sauce by whisking together the water, coconut aminos, brown sugar, garlic, ginger and sesame oil and pour into the slow cooker. The sauce can also be made ahead of time and stored in a glass airtight container in the fridge for up to 1 day.
  4. Cook on low for 4-5 hours or on high for 2-3 hours.
  5. During the last hour of cooking time, add in the shredded carrots.
  6. Prepare your rice and veggie side dish.
  7. Serve your Mongolian Beef with a generous sprinkling of sesame seeds and sliced green onions on top.


What kind of beef do you use in mongolian beef?

A lot of recipes you will find for Mongolian Beef will use flank steak but I choose to use chuck roast. Chuck roast has a rich and beefy flavor, and is PERFECT to use in a slow cooker because it gets so tender!


Flank steak is also a great choice but I prefer to use a chuck roast as it is usually cheaper per pound and it gets really melt in your mouth tender – and when you are feeding babies and little kids, you want beef to be as tender and as easy to eat as possible, right?


A Note About Soy Sauce vs Coconut Aminos:

The base of this sauce uses Soy Sauce, which is an awesome flavor additive here. But its super high in salt, which isn’t good for little growing bodies. Even reduced/low sodium versions of Soy Sauce are super high in salt content! For this recipe I chose to substitute the soy sauce with coconut aminos. Coconut aminos is a sauce that is made out of sap from coconut flowers and salt. It is dark, rich, and has a salty-sweet flavor. It is a great gluten free, soy free alternative to soy sauce that is also packed with vitamins and minerals, so it adds nutritional value to the meal. You can find it in the health food section of most grocery stores or on Amazon.

Tips and tricks for making this slow cooker mongolian beef

  • Slice your chuck roast against the grain. When you look at your roast, you will see lines that kind of resemble the grain on a piece of one. You want to slice perpendicular to these lines, not parallel to them. This will help ensure tender pieces of beef.
  • The shredded carrots are optional, but add fun color and texture to the meal. Totally go ahead and buy the pre-shredded matchstick bag of carrots in the produce section of your grocery store. Its worth it.
  • If you don’t want your onions and peppers soft, you can toss them in only for the last hour. You can also sub out red, orange, or yellow sweet peppers, depending on what your family likes.
  • To make this a complete meal, serve this with steamed broccoli and rice.
  • Leftover of this are just as awesome as they are right when you make it!


How to serve this weeknight Asian meal to your family:

  • To serve to toddlers – To serve this mongolian beef recipe as finger foods,
  • For children – To serve to children, place the meat and rice in separate piles on their plate. Serve with a veggie and a fruit on the side, so they have 4 piles of different colored foods to choose from.
  • Plating for adults – Serve over rice and with a veggie. Stir in some sriracha or gojuchang sauce or a pinch of red pepper flakes to spice things up a bit.

What kind of pepper do I use?


Wednesday 16th of November 2022

This is delicious! I add crushed red pepper and dried peppers in the sauce for a little extra kick. I also add a little siracha over the top too as I eat it.
