Mongolian beef in a wok.

Mongolian beef is a popular Chinese-American restaurant dish that consists of tender, crispy beef in a savory-sweet brown sauce. This version comes from The Woks of Life, written by Bill, Judy, Kaitlin, and Sarah Leung, the family behind the popular Woks of Life blog. I’m a big fan of the cookbook and the blog, both of which are excellent resources for anyone interested in learning more about Chinese cooking.

To prepare the dish, thinly sliced flank steak is first “velveted” or tenderized by marinating it in a mixture that includes baking soda, before being coated in cornstarch. The beef is then shallow-fried in a wok or skillet until crispy, and tossed in a flavorful brown sauce made with soy sauce, brown sugar, garlic, ginger, and scallions. Served over steamed rice, the dish is a huge family-pleaser and every bit as good as the Mongolian beef served at your favorite Chinese restaurant.

What You’ll Need To Make Mongolian Beef

mongolian beef ingredients
  • Soy sauce: Two kinds are called for: regular and dark soy sauce. Dark soy sauce is saltier, sweeter, and a bit thicker than regular soy sauce. It used to flavor dishes and also darken the color of sauces, and you only need a small amount. You can find it at Asian markets or online. If you don’t have any, you can simply omit it but your dish will be lighter in color. Alternatively, you can make a substitute by combining 2 teaspoons soy sauce, 1/2 teaspoon molasses, and 1/8 teaspoon sugar.
  • Cornstarch: Used for thickening, dredging, and binding in Chinese cooking. As a thickener, cornstarch needs to be dissolved in water before adding it to simmering liquid. It makes more robust, glistening, visually appealing sauces. Cornstarch also works well in batters and crispy coatings, and helps seal in juices of meat before cooking, resulting in tender meat.
  • Shaoxing wine: A type of Chinese rice wine that helps give Chinese food its distinctive flavor. Dry sherry can be substituted.
  • Dried whole red chili peppers: A common ingredient in Chinese cooking, these peppers are made by drying fresh red chili peppers until they become hard and brittle. You can usually find them in the produce section at the supermarket.
  • Baking soda: Used in Chinese cooking as a meat tenderizer. When mixed with water, baking soda creates an alkaline solution that can break down the tough fibers in meat, making it more tender. The process of using baking soda to tenderize meat is known as “velveting.”

Heat the oil in a wok or large nonstick skillet over high heat until just before the oil starts to smoke. Working in batches so as not to crowd the pan, spread the beef slices evenly in the wok or skillet and shallow-fry them undisturbed for 1 minute on each side to achieve a crusty coating. Transfer the beef to a plate and turn off the heat.

Servings: 4
Prep Time: 30 Minutes
Cook Time: 15 Minutes
Total Time: 45 Minutes, plus 1 hour to marinate

Ingredients

For Marinating the Beef

  • 1 pound beef flank steak, sliced against the grain into ¼-inch-thick slices
  • 2 teaspoons vegetable (or neutral) oil
  • 2 teaspoons Shaoxing wine (or dry sherry)
  • 1 teaspoon regular soy sauce
  • 1 tablespoon cornstarch
  • 1 tablespoon water
  • ¼ teaspoon baking soda

For the Sauce

  • ¼ cup (packed) light brown sugar
  • ¾ cup hot water
  • ¼ cup regular soy sauce
  • 1 teaspoon dark soy sauce (see note)

For Coating and Searing the Beef

  • ½ cup cornstarch
  • ⅔ cup vegetable (or neutral) oil

For the Rest of the Dish

  • 1 teaspoon minced fresh ginger
  • 8 dried red chilies (optional)
  • 3 medium garlic cloves, finely chopped
  • 4 scallions, white and green parts separated and cut on an angle into 2-inch pieces
  • 1½ tablespoons cornstarch
  • 2 tablespoons water

Instructions

Marinate the Beef

  1. In a medium bowl, combine the beef with the oil, Shaoxing wine (or dry sherry), regular soy sauce, cornstarch, water, and baking soda. Marinate for 1 hour.

Make the Sauce

  1. In a small bowl, dissolve the brown sugar in the hot water. Mix in the regular soy sauce and dark soy sauce.

Coat and Sear the Beef

  1. In a medium bowl, dredge the marinated beef slices in the ½ cup cornstarch until thoroughly coated.
  2. Heat the oil in a wok or large nonstick skillet over high heat until just before it starts to smoke. Working in batches so as not to crowd the pan, spread the beef slices evenly in the pan and shallow-fry them undisturbed for 1 minute on each side to achieve a crusty coating. Transfer the beef to a plate and turn off the heat.

Assemble the Dish

  1. Drain most of the oil from the pan, reserving 1 tablespoon. Wipe the pan clean with a paper towel, then add the reserved tablespoon of oil. Over medium-high heat, add the ginger and whole dried chilies (if using—if you’d like the dish spicier, break 1 or 2 chilies in half). After 15 seconds, add the garlic and the scallion whites. Stir-fry for another 15 seconds. Add the sauce and simmer for 2 minutes.
  2. In a small bowl, combine the cornstarch with the water to make a slurry, then slowly stir it into the pan.
  3. Add the beef and the green parts of the scallions. Toss everything together for 30 seconds, until the scallions are wilted and there is almost no standing sauce. Serve.
  4. Note: Dark soy sauce is saltier, sweeter, and a bit thicker than regular soy sauce. It is used to flavor dishes and also darken the color of sauces, and you only need one to two teaspoons. Dark soy sauce is available at Asian markets or online. If you don’t have any, you can simply omit it. However, your dish will be lighter in color. If you want your dish to look like the photograph, don’t leave it out. (Alternatively, you can make a substitute by combining 2 teaspoons soy sauce, ½ teaspoon molasses, and ⅛ teaspoon sugar.)

  • I’m still chewing my last bite and had to comment. This was awesome! I read the directions numerous times because I know flank steak could turn into shoe leather……when I was done this needed only a fork to cut into. Thank you for this, flank steak no longer intimidates me.

  • This was the worst recipe I have made in a long time. Followed the recipe exactly. Beef was slimy and chewy. Ginger/garlic tastes were neglishable. So sad, because it sounded yummy.

  • This was fantastic! I took a trip to our local Chinese grocery store to buy the dark soy sauce and the Shaoxing wine. Will definitely be making this again! This recipe inspired me to buy the Woks of Life cookbook too!

    • Hi Angi, Can you get flat iron steak? That would be a good option. You could also use sirloin.

  • Think you could sub hoisin sauce for the dark soy sauce?

    • Hi Dani, I don’t think hoisin sauce will give you the same effect. I would make the molasses substitute instead. Sorry!

  • Can arrowroot be substituted for the cornstarch since I have a corn allergy?

    • Hi Megan, To be honest I’m not sure how arrowroot will work with Chinese cooking. I would ask the folks over at The Woks of Life – I’m sure they will have a better answer than I would.
