Enjoy a healthier, homemade version of the classic Chinese takeaway favorite. This air fryer recipe delivers perfectly crispy beef strips tossed in a sticky, sweet, and spicy sauce that's ready in just 30 minutes.
In a medium bowl, whisk together the Chinese five-spice, sesame oil, caster sugar, and soy sauce to create a marinade. Add the steak strips and toss until thoroughly coated. For the best flavor, let the beef marinate in the fridge for up to 24 hours, or proceed immediately if you are in a hurry.
Sprinkle the cornflour over the marinated beef and mix well until each strip is coated in a thick, floury paste. Separate any clumped strips and arrange them on a plate. Lightly drizzle the beef with a little vegetable oil to help it crisp up. Preheat your air fryer to 220°C if a preheat setting is available.
Carefully place the beef strips onto the air fryer cooking rack in a single layer. Cook for 6 minutes, then turn the strips over and cook for an additional 4–6 minutes until the beef is dark brown and very crispy.
While the beef is air-frying, heat 2 tablespoons of vegetable oil in a wok or large frying pan over high heat. Add the garlic, ginger, sliced chilli, red pepper, and the white parts of the spring onions. Stir-fry for 2–3 minutes until the pepper softens, being careful not to burn the aromatics.
Stir in the rice wine vinegar, sweet chilli sauce, and tomato ketchup. Mix well and cook for about a minute until the sauce is bubbling and slightly reduced.
Add the crispy air-fried beef to the wok and toss quickly to coat every piece in the sauce. Cook for one more minute until everything is piping hot. Serve immediately, scattered with the reserved green parts of the spring onions.
For maximum crispiness, ensure the beef is sliced very thinly across the grain. Do not overcrowd the air fryer basket; cook in batches if necessary to allow the air to circulate. If you prefer a milder dish, remove the seeds from the red chilli before slicing.
