Toss the cut parsnips with all of the remaining ingredients and mix well.
Carefully arrange the parsnips on the hot sheet pan in one singe layer.
Cook for 25 minutes, flip the fries over if they look well browned on top, and cook for another 10-20 minutes until well browned.
If the fries are not browned on top after 20 minutes, don't bother turning them, just continue cooking.
