Step 1

Combine the marinade ingredients in a bowl, then pour over the beef strips. Mix well so the beef is coated - at this stage you can either refrigerate overnight for maximum flavour, or continue on with the next step.

Step 2

Pour the cornflour over the beef strips and mix together using a spoon (or your hands!) - it should form a thick, sticky batter which coats all the beef pieces.

Step 3

Liberally spray the air fryer basket (with grill tray) with spray oil. Lay the beef strips out in one layer, with some space between them. I have a dual-basket air fryer with smaller baskets, so I divided the beef between the two. Alternatively you could cook this in batches - the space is crucial to ensure the beef goes crispy!

Step 4

Air fry at 220C (428F) for 6 minutes, then open the drawer and turn the beef over. Air fry for another 4-5 minutes at 220C (428F) until crispy and sizzling.

Step 5

Turn the beef strips into a bowl and serve with sweet chilli sauce and chopped spring onion on top. Great with gluten free noodles or rice, or your favourite Asian dishes!
