Frequently Asked Questions About Mongolian Beef
Before I share my Chinese Mongolian beef recipe, here are a few questions I have gotten from our readers that I wanted to share:
What Kind Of Protein Can I Use To Make This Recipe?
For this recipe, I prefer to use a chuck roast or flank steak because it really soaks up most of the flavors quickly and it doesn’t come out chewy as other cuts of beef do.
If you are wanting to make a vegan or vegetarian version of this dish, you can replace the beef with some tofu as your protein. You will want to make sure to buy extra-firm so that the tofu doesn’t completely fall apart while it’s cooking. You may also need to adjust the cooking time.
What Kinds Of Vegetables Can I Add In With The Beef?
Typically, you will find Mongolian Beef is served with some chopped scallions sprinkled over the top. I personally love to add some steamed broccoli or carrots to add in some of those healthy veggies. You can also add in some green snowpeas or chopped bell peppers (preferably the red ones) to give the meal some texture.
How Can I Make Mongolian Beef Gluten-Free?
If you are allergic to gluten or are living a gluten-free lifestyle, then you can substitute soy sauce with tamari. It’s made in the same way as soy sauce (from soybeans) except it doesn’t have any of the wheat.
If you want to try something else, here’s a list of more alternatives for soy sauce.
Also, make sure you double-check some of the other ingredients such as the hoisin sauce since most of the time it is made with regular soy sauce!

How To Make Mongolian Beef Sauce And Marinade
One of the most important components (if not, the most important) of this dish is the sauce. This will make or break this dish!
Lucky for you- I have the perfect recipe.
Add in the olive oil, garlic, soy sauce, water, brown sugar, ginger, and hoisin sauce in a large bowl. Using a whisk, mix the sauce until the brown sugar as completely disintegrated.
Add in the thickly chopped onions and cubed meat to your sauce/marinade. Gently stir everything together to make sure it is evenly coat.
Cover the bowl with some plastic wrap and place it in the fridge for at least 4 hours to allow it to marinate; however, 24 hours works best!
How To Make This Recipe For Mongolian Beef
After your meat and veggies have marinated, place the ingredients into the slow cooker and cook for 4 to 4 ½ hours on HIGH or 7 – 8 hours on LOW.
During the last 8-10 minutes, add in the chopped green onion stalks and stir with the meat to cook until the green onions have wilted just a little bit.
Remove the meat and onions from the liquid in the slow cooker. Drain the liquid into a small pot on the stove on medium heat. Whisk in the cornstarch slurry until the sauce starts to bubble and thicken which will take just a few minutes.
Once it’s done, serve this Mongolian Beef over rice (optional), add some of the sauce, and garnish with sesame seeds.
- Instead of cutting your own chuck roast, you can use stew meat or pre-sliced steak fajita meat.
- If you don’t have fresh ginger, you can replace it with ¾ teaspoon of dried powdered ginger. Of course, if you love ginger, then you can always add more of either fresh or powdered ginger.
- If you want more of a sesame flavor profile from your beef, you can add 1 teaspoon of sesame seed oil.
