Easy Mongolian Beef
This Mongolian beef stir fry is amazingly simple to make at home and requires no deep frying. We are simply marinating the beef and then coating it in cornstarch. Next, we’ll shallow fry the beef until crispy. Finally, we’ll fry the aromatics and pour in the pre-mixed sauce to thicken and reduce. Adding the beef back into coat. Optionally, you may garnish with green onions or sesame seeds to enjoy!
No deep frying
You heard me right! No deep frying. Instead, we are shallow frying, which reduces the amount of oil needed and reduces the amount of mess to clean up later.

How to make Mongolian Beef
Below are brief steps with visuals to show you how to make Mongolian Beef. Please scroll down to the recipe card below to find full instructions and details.
Thinly slice beef against the grain into 0.75 cm thick pieces and 2 inches in length. Do not slice any thinner.
Marinate beef with marinade ingredients and set aside.
In a bowl, combine sauce ingredients.
Generously dredge several beef slices into cornstarch until well coated and transfer to a plate. Repeat this process until all your beef is coated.
Over medium heat, heat oil. Check if oil is hot by inserting a wooden chopstick and look for bubbles.
Once oil is hot, fry beef in batches 1 minute on each side until slightly crispy. Important: Immediately spread beef apart to prevent sticking. Fry in 2-3 batches to prevent overcrowding.
Remove cooked beef from oil and set aside. Discard excess oil leaving 1 tsp in the pan.
Over low heat, sauté ginger, garlic, red chili for 10 seconds.
Pour in sauce to reduce and thicken.
Once thick, add beef and mix to coat evenly. Garnish with green onions.
Remove off heat. Optionally garnish with sesame seeds. Enjoy!
Cooking Tips
Below are tips on making my slightly spicy Mongolian beef:
Freeze flank steak for 30 minutes to make slicing easier!
This is a trick I’ve learned from countless chefs and I’m passing it on! If you freeze your beef for 30 minutes, it will make slicing the beef into thin pieces much easier.
Baking soda helps to tenderize meat
In case you’re wondering why we’re adding baking soda to the beef, this is a popular meat tenderizing agent used in Chinese cuisine to make meat tender.
Coat beef generously in starch for crispy texture
Ensure your beef is evenly coated in the cornstarch if you want a crispier beef texture.
Do not over fry your beef
Since we are frying the thinly sliced beef in hot oil, it’s important not to over fry it or it’ll too crispy and dry.
Simmer sauce over LOW heat
Because this sauce contains a high amount of sugar thanks to the hoisin and brown sugar, it’s important to first simmer the sauce over low heat to avoid burning.

NOTES
Tastes like you ordered from a Chinese restaurant and so easy to make! For some reason I’ve always been a bit intimidated by flank steak but it was really easy to cut, especially with her tip to freeze for 30 mins, and also easy to cook. I air fried some broccoli and served with rice and it was perfect.
Thank you so much Emma for making my Mongolian beef! I'm so glad the tip to freeze the flank steak was helpful!
