  • Olive Oil: Use canola oil if you’d rather.
  • Garlic: Minced or chopped will give the most flavor.
  • Soy Sauce: Either low-sodium soy sauce or coconut aminos can be used here.

Tips and Variations

Everything about this Mongolian recipe is perfect, and I know that it will become a family favorite at your house just like it did at ours! Here are some ideas and variations to make it your own! I also included instructions for making it in the instant pot when you’re short on time!

  • Slicing the Beef:When slicing the flank steak make sure to slice it against the grain. I like to slice mine about 1/4 inch thick.
  • Veggies: Roast broccoli, green beans or red bell pepper then stir in before serving. Vegetables add texture and nutrition.
  • Instant Pot:This easily converts to a quick Instant Pot recipe. Saute the steak on high until browned. Add the sauce ingredients and cook on “Manual” for 10 minutes. Lastly, quick release the pressure and enjoy!

How to Store Leftovers

Store any leftover Mongolian beef you may have, because it’s great for heating up and enjoying later! I like to make a little extra rice as well for a quick lunch that’s super satisfying!

  • In the Refrigerator:Place leftovers in a sealed container for up to 4 days.
  • In the Freezer:Once cooled, store leftovers in an air-tight container or freezer ziplock bag for up to 4 months. Thaw in the refrigerator before rewarming.
  • To Reheat: Place leftovers in a microwave-safe bowl then heat for 1-2 minutes or until warmed through.
