Firstly, slice the parsnips in half lengthways (I don't peel mine)
Add to a large bowl with a drizzle of olive oil, pinch salt and toss until evenly covered then place on a baking tray and bake for 30 minutes at 200°C fan (220°C conventional, gas 7)
Meanwhile, make the glaze by adding the mustard, maple syrup, olive oil, pinch salt to a mixing bowl and whisk until smooth
Remove the parsnips from the oven, place into the bowl with the glaze and coat all evenly before placing back on the baking tray and roasting for a further 10 minutes
