Peel the parsnips and cut lengthwise into the shape of thick French fries.
Place them in a mixing bowl with cold water and ice cubes.
Soak for 30 minutes.
Preheat oven to 400°F.
After soaking the parsnips, drain them and then pat dry with a paper towel.
Place the parsnips and salt in a zipper bag with the rosemary and pepper.
Spray the parsnips for about three seconds with the oil and seal the zipper bag.
Shake to coat the parsnips well with the oil and salt.
Carefully place the parsnips on a non-stick cookie sheet. Avoid the fries touching each other.
Spray lightly with the oil.
Place the cookie sheet in the oven and allow the parsnips to bake for about 7 minutes.
Turn the parsnips at least twice, cooking for about 7 minutes after each turn.
Total cooking time will be 20 – 25 minutes.
Serve immediately.
