There is just so much to love about Mongolian beef in general and especially this recipe because it’s filled with tender strips of flank steak and swimming in a sweet yet savory sauce. It’s also so easy to prepare, is better than take out (yes, better than take out from your local Chinese restaurant!) and can get dinner on your table in 30 minutes or less. Can I get a heck ya?!

Flank Steak: This Easy Mongolian beef recipe uses flank steak. Sirloin can be used too but we always opt for Flank Steak. Both cuts are tender and will cook up quickly when thinly sliced. I would steer clear of stew meat. Corn starch: An important ingredient! It helps lock in the juices in the flank steak acting as a natural tenderizer, thicken the amazing garlic ginger sauce and creates a crispier crust on the meat too. Brown sugar and soy sauce: Classic ingredients for making Mongolian Beef. I recommend using dark brown sugar and you can use low sodium soy sauce if preferred. Beef Broth: I like using beef broth when making the sauce for a little more flavor, but you can also use water instead. Canola oil: Used for frying the beef. You can also use vegetable oil. Baking Soda: Using a pinch of baking soda helps to tenderize the flank steak even more! I swear this Mongolian beef just melts in your mouth because of it!
Slice the flank steak against the grain into very thin strips. Combine flank steak with 1 Tbsp. soy sauce, cornstarch and baking soda. Let sit 10 min. Heat oil in a wok and sear flank steak in batches, about 1 minute each side. Set aside on a plate. Repeat with remaining beef. Add garlic and ginger to wok and cook 1 minute. Do not let it burn. Add in soy sauce, beef broth, sesame oil and brown sugar. Whisk to combine and bring to a simmer. Add beef back into sauce, toss to coat in sauce. Add in green onions and dried red chilies. Cook until sauce thickens and becomes glossy, 3-4 minutes. Garnish with sesame seeds and serve.
