Instant Pot Mongolian Beef cooks up in under 30 minutes. This sweet, flavorful Asian-style beef is so much better than takeout and so easy to make.

 
Mongolian Beef is my absolute favorite Asian-style meal. I love the sweetness in it. I also love to make it at home so I can control the amount of spice in it. I add a good bit of crushed red pepper flakes to balance the sweetness and sometimes I like to add a little Sriracha sauce when I dish it up.
This Instant Pot Mongolian Beef is fabulously sweet and salty with lots of ginger and garlic flavor. The sauce is a wonderful mixture of soy sauce, dark brown sugar, rice vinegar,  sesame oil, garlic, ginger, and crushed red pepper flakes. So much flavor!

 
Tips for making Instant Pot Mongolian Beef:
Mongolian Beef is no better than the quality of the beef you use. I use flank steak for my Mongolian Beef. It is a little pricey, bit I really believe it is the best cut of beef for this dish.
To make the flank steak easier to slice, freeze it for 30 minutes and use a very sharp knife.
The key to great Mongolian Beef is coating the beef in cornstarch and frying it in oil. Do NOT substitute flour. The cornstarch gets the beef really crispy.
You will need to saute the beef in multiple batches in the Instant Pot which is kind of a pain.
It’s convenient to saute in the Instant Pot but it is also very small. If you prefer, do it on the cook top in a large skillet. You will have one more thing to clean, but you will save...
