Put the parsnips into a bowl. Add the oil, honey, mustard, salt and pepper. Mix well so that all the parsnips are coated.
Put the coated parsnips into the air fryer.
Cook at 200°C/400°F for 13 minutes, shaking the basket halfway through.
Notes
How you cut your parsnips will depend on how big they are. You might be able to just slice them lengthways in to 4 pieces, but if that is too big then half the whole parsnips so you have a top and bottom and then cut each of those into 4.
Make sure the parsnips are cut to the same size so that they cook at an even rate.
Make sure everything is well mixed in the bowl so all the parsnips are fully coated.
You don't have to peel the parsnips, but we prefer the texture of when they are peeled.
