Place your potatoes between a pair of chopsticks and finely slice to create the hasselback effect. The chopsticks will prevent the knife from cutting all the way through.

Add sliced potatoes in a large mixin bowl with the olive oil and a generous pinch of salt. Mix well.

Cook for 20-minutes at 200°C in an air fryer, shaking half way through, until golden and crispy.

Serve and finish with fresh herbs and freshly grated Parmesan cheese.
