Top and tail the parsnips, then slice lengthways, about 2 cm/¾ in. wide.
Place in a saucepan with water to cover and a good pinch of salt.
Bring to the boil, then boil for 5 minutes.
Remove and drain well, allowing any excess water to evaporate.
Dust the parsnips with flour.
Mix together the honey and oil in a small bowl, then toss in the parsnips to coat well in the honey and oil.
Preheat the air-fryer to 180°C/350°F.
Add the parsnips to the preheated air-fryer and air-fry for 14-16 minutes, depending on how dark you like the outsides (the longer you cook them, the sweeter they get).
