Mongolian beef is one of those Asian-inspired dishes that has taken over American cuisine. These delicious strips of beef are coated in a thick soy-flavored sauce and usually stirfried for oodles of flavor.
But if you don’t have time to watch over your stove for 20 minutes or so, try popping them in the air fryer. They come out beautifully brown and juicy on the outside and tender on the inside.

Now, the sauce does need a bit of cooking on the stove top, since the air fryer has never been known to make good stews or sauces. But it is only 1-2 minutes for the soy to meld with the sugar and blend together, compared to the amount of time it would take for the beef to stir fry.
Other than that, my main tip would be to cut the beef across the grain using a sharp knife for easier meat preparation. Cut the beef into 1/4 inch slices, so that it is neither too thick or too thin. And it is just as easy as that!
Type of beef
You can use any type of cut of beef such as flank steak, sirloin, or even filet which is a finer and more expensive cut of beef. I do like to use fresh cuts of meat from the butcher for this recipe, as the beef is very much the star of the dish.
Cooking tips
- Preheat the air fryer to 375°F (190°C) before cooking the steak.
- It is better to watch carefully and underestimate the time required to cook the steak, and then tack on a minute at the end, rather than to overcook the steak.
- Do not use sweet soy sauce, but rather salty or low-sodium soy sauce. Otherwise the peanut sauce will have quite a different taste!
