Ingredients
  

Beef

  • 1 lb flank steak sliced against the grain
  • ¼ cup cornstarch

Sauce

Instructions
 

  • Place the beef strips and cornstarch in a large, resealable baggie and shake to coat.
  • Cook the beef at 390 in a preheated air fryer for 5 minutes, flip, and cook for another 5 minutes.
  • While the beef is cooking, mix all the sauce ingredients in a saucepan and bring them to a boil, stirring constantly.
  • Reduce the heat and simmer until thickened. Add an additional teaspoon of cornstarch if the sauce is too thin.
  • Mix the beef and sauce ina large bowl and let it sit until the sauce thickens further. Enjoy!

Notes

Storage
  • Refrigerate leftovers in an airtight container for up to 4 days. 
  • For longer storage, freeze the beef for up to 3 months in an airtight, freezer-safe container. 
  • To reheat, defrost the beef if frozen. Then, add it to a saucepan with a bit of water and cook on medium-low until heated through. 
Choosing Beef
  • Look for flank steak that is bright red, not dull or gray. 
  • This dish cooks quickly, so choose the leanest flank steak possible. You don't need marbling to get it tender when you cut it against the grain. 
General Tips
  • Always preheat your air fryer for even cooking and precise cooking times. You'll always get a better final product, and it only takes a few minutes. 
  • We mentioned this earlier, but it bears repeating. ALWAYS cut your flank steak against the grain. If you cut with the grain, it will NEVER get tender. 
  • You can spray your meats with cooking spray when you air fry, but never spray your air fryer basket directly with nonstick spray. It can damage the coating over time.
