Preheat oven to 400 degrees with rack in center of the oven.
Peel carrots and parsnips and halve crosswise. Slice lengthwise into 1/4-inch-thick planks. Slice lengthwise again to make 1/4-inch-thick fries.
Place on a rimmed baking sheet and toss with oil, salt, and red pepper flakes. Spread into a single layer and roast, turning veggies once, until crisp and golden brown in places, about 20 minutes.
