Peel 1.5kg potatoes and cut into large chunks. Add to a large pan

Par boil the potatoes for 7 or until you can insert the tip of a sharp knife

Drain the potatoes thoroughly in a colander

Toss the potatoes in the colander to rough up the edges. Leave the potatoes to steam dry for a few minutes

Preheat your air fryer if needed

• Put the potatoes back in the pan and add 2 tbsp oil and 1 tsp sea salt

• Add the potatoes to your air fryer basket – you might need to do this in batches. Make sure you don’t over crowd the basket

Cook the potatoes for 25 minutes at 190°C, turning half way

If you want them even more crisp you can cook them for a little longer, just check them every few minutes
