Many many years ago, OK maybe not that many, but when I used to work in Michigan I had a favourite restaurant. That restaurant was PF Chang’s. I used to love going there for lunch or dinner. It used to be in the mall, so whenever we’d go shopping at the mall we’d always stop by PF Chang’s. Oh how I miss this place. My favourite dishes were the chicken lettuce wraps and the Mongolian beef, though trust me when I say I tried almost everything there.

This copycat recipe of PF Chang’s Mongolian beef is so good, probably better than the original. Probably. It’s like candy. You won’t be able to stop eating it. It’s so freaking good. I’m serious.

The great thing about this amazing recipe is how simple it is to make. The ingredients are simple ingredients you probably have in your pantry right now. But beyond that, as you bite in this yummy beef you will know what I’m talking about. It melts in your mouth, it’s sweet and a bit salty, and the flavour is out of this world.

The only thing I’m sad about now is that it’s all gone. I had the last of it at lunch and it was the best lunch ever. I guess I’m just going to have to make it again.

Serves: 6
Ingredients
  • 2 lb flank steak
  • ½ cup cornstarch
  • ½ cup vegetable oil
For sauce
  • 2 tbsp vegetable oil
  • 1 cup soy sauce
  • 1 cup brown sugar
  • 4 cloves garlic, minced
  • 1 cup water
  • 2 or 3 green onions chopped
Instructions
  1. Slice the steak into small thin pieces against the grain. In a large ziploc bag add the starch and add the beef to it. Close the ziploc bag and shake really well until each pieces is coated with cornstarch. Refrigerate until ready to use.
  2. In a small sauce pan add the oil, soy sauce, brown sugar, garlic and water. Stir and cook over medium heat until sauce thickens. It took me about 20 minutes until the sauce thickened and reduced. Set aside.
  3. In a non stick skillet heat the oil. When the oil is hot, add beef and cook until browned. I had to do in a 2 batches. Also if you need more oil after the batch feel free to add more. Remove beef from skillet to a bowl and empty the oil from the skillet. Return beef to skillet and pour sauce over the beef. Stir and cook for a couple more minutes.
  4. Serve over rice and garnish with green onions.

    So, I’ve never had this at PF Changs, and I NEVER cook beef. But the photo of this looks so good I had to try it…

    And it turned out AMAZING! I even commented to my roommate “it looks like a real Chinese food dish!” It was so good.

    I was nervous about picking and cooking the beef. I couldn’t find flank steak, so I went with a London Broil. Worked out perfectly!

    My sauce never really thickened up in the pot, but once added to the meat, I’m guessing because of the corn starch in the meat, it thickened nicely.

    Thanks for the great recipe!

    Does the cornstarch do something different than tossing it in flour? I have both but figured I would ask. Thanks Jo. I can’t wait to make this. :)

      Hi Jessica,
      Both cornstarch and flour are thickening agents, the difference is flour has gluten and cornstarch is just pure starch. The gluten also reduces the thickening power of flour so cornstarch has twice the thickening power. Sauces thickened with cornstarch will be clear, and opaque with flour.
      Hope this helps.

    Thank you for the recipe. It was delicious and a hit with the whole family! I didn’t have flank steak available but my butcher recommended substituting with sirloin. The sauce thickened up just fine…it just truly needs the 20 minutes cook time because it thickens up in just those last few minutes. For me, the cook time was forever because I don’t have a non stick pan. This recipe may just push me to get an orgreenic because I’d love to make this again with a shorter cook time. The kids all told me this meal was a “do over” LOL!

    Firstly thank you for the recipe. Secondly, it turn out great. I used low sodium soy sauce but it was still a little salty, but not inedible. I think next time I will add more water and less soy. Lastly, if I made a batch of the sauce to have on hand, do you think It will keep for a while.

    Hi. This has quickly become my families favorite. We all love it. I don’t like however when I am stir frying the beef that it all gets kind of stuck and thick on the bottom of the pan making stir frying a little difficult. I didn’t use a non stick pan because typically for Asian type food you don’t use a non-stick pan. Is that the only way to have it stir fry properly because of the cornstarch? Thanks!

      Hi Erin,
      As I’m not there in the kitchen with you, it’s hard to tell what you did wrong. As mentioned in the instructions, it does take about 20 minutes for the sauce to thicken.

    I would like to substitute chicken for beef (that’s what I have on hand) your pictures look so good i want to try it.

    Would I need to change anything
    Thanks

      I made the recipe. Used chicken instead of beef. Very easy recipie. I will make it again for sure. But I will reduce the soy sauce. It Was to salty, I used the low sodium soy sauce.

      Thank you for a lovely meal recipe.

  7. Diciendo says

    Just tried this recipe, which is awesome and easy. But my dish came out a bit on the salty side, and I followed the directions exactly step by step. Should I reduce the soy sauce, increase the water or use low sodium soy sauce? Thanks for the recipe!

    • says

      I used low sodium sauce, but you could do both, either use low sodium soy sauce or use less soy sauce and add a bit more water.

    Oh my gosh! It’s been eons since I’ve been to PF Changs and I’d completely forgotten about the Mongolian beef!! SOOOOOGOOOODDDD!!!!

    Squee! I can’t wait to try it!

    ps- I tried to photograph a casserole the other day per your instructions and I failed. It was epic. As I tried to hold my camera and get it to focus while keeping my hand steady over the dish as the sun was rapidly setting and time was running out, I thought, “Jo would totally HAVE this!”
