How to Make Slow Cooker Mongolian Beef

Making Slow Cooker Mongolian Beef is a delightful experience, and trust me, it’s as easy as pie—if pie were made in a slow cooker, that is. First things first, you’ll need to grab that 1 1/2 lbs of beef flank steak. Cut it into stir-fry sized strips; think bite-sized pieces that will soak up all that yummy sauce.
Now, don’t be alarmed, but you’re going to coat these strips in 1/4 cup of cornstarch. It may sound a little odd, but this step is essential for achieving that nice, glossy texture later on. Once they’re all coated, toss them into your slow cooker. Feel free to give the slow cooker a spritz of non-stick cooking spray before this step, just to keep things nice and tidy—nobody likes scraping burnt bits off, right?
Now, let’s move on to the sauce that makes this dish sing. In a separate bowl, combine 3/4 cup of soy sauce, 3/4 cup of water, and 3/4 cup of brown sugar. You’ll also want to mince up those 2 garlic cloves and toss them in, along with 1/2 cup of shredded carrot that adds a lovely sweetness and texture.
Give it a good stir to meld all those flavors together—this is where the magic happens. Pour this glorious concoction over the beef in the slow cooker. Now, cover and set your slow cooker on high for 2-3 hours or low for 4-5 hours. And here’s a little tip: if you’re like me and tend to forget about dinner, the low setting is your friend. It gives you a little more leeway, and you won’t have to rush back to the kitchen.
As the hours go by, you’ll be greeted by the delightful aroma wafting through your home—seriously, you might even start to think your neighbors are going to be knocking on your door asking for a taste.
When it’s finally time to eat, serve this tender, flavorful beef over a bed of rice and top it off with those lovely sliced green onions. Just picture it: a steaming bowl of Mongolian Beef, rich and savory, a warm hug after a long day. You might even want to make a double batch because leftovers? They’re just as good, if not better.
Slow Cooker Mongolian Beef Substitutions & Variations
If you’re looking to switch things up a bit, there are plenty of substitutions and variations for Slow Cooker Mongolian Beef that can keep your taste buds excited.
You can swap the flank steak for chicken or tofu for a lighter option. Instead of brown sugar, try honey or maple syrup for a different sweetness.
Adding bell peppers or snap peas can enhance the veggie factor. For a spicy kick, toss in some red pepper flakes or sriracha.
Don’t forget, you can also play around with different types of soy sauce, like tamari for a gluten-free version.

What to Serve with Slow Cooker Mongolian Beef
While Slow Cooker Mongolian Beef is a delicious main dish on its own, pairing it with the right sides can elevate your meal to new heights.
I love serving it over fluffy white rice, which soaks up the savory sauce beautifully. For a pop of color and crunch, steamed broccoli or sautéed snap peas work wonders.
If you’re in the mood for something lighter, a simple cucumber salad with sesame dressing complements the rich flavors perfectly.
Finally, don’t forget about warm egg rolls or spring rolls on the side for an extra touch of crunch and flavor.
Enjoy your meal!
Additional Tips & Notes
A few simple tips can make your Slow Cooker Mongolian Beef even better.
First, for added flavor, marinate the beef in soy sauce and garlic for a few hours before cooking. I also like to use fresh ginger for a little extra zing.
If you want a thicker sauce, mix a tablespoon of cornstarch with cold water and stir it in during the final 30 minutes of cooking.
Ultimately, don’t skip the green onions; they add a fresh crunch that balances the sweetness.
