1. Preheat the air frying oven to 200°C and turn the timer dial to 5 minutes.
  2. Cut the potatoes into even sized chips about 1cm thick. Tip: trim ½ cm off each side. Once the potato resembles a rectangle, cut it into chips. The thicker the chip will be, the longer the cooking time.  
  3. Place chips in a bowl and coat with olive oil, salt and 2 rosemary sprigs. Ensure all the chips are evenly coated and do not stick together. If they stick together, they will not cook properly.
  4. Once the ‘HEATING’ light goes off, turn the timer dial to 30 minutes.
  5. Place the chips into the Air Chef basket and allow to cook, shaking every 5 minutes for best results. Shaking them regularly ensures the chips don’t stick together and provides a more even cooking.
  6. Once the chips have finished cooking, remove from the air frying oven into a bowl. Sprinkle with salt and pepper. Grate the parmesan over and sprinkle the remainder of the rosemary. Enjoy.
