Preheat the oven to 375 degrees F.
Peel the parsnips and slice off the root. Cut into thick fries as evenly as possible. In a large bowl, mix together the olive oil, chile powder, garam masala, salt, and pepper. Add the parsnips and toss to coat. Place on a parchment or foil-lined baking sheet.
Roast for 40 to 45 minutes, tossing the chips halfway through to ensure even cooking. Chips are done when they're lightly caramelized and a knife inserted in the chips goes in and comes out without much resistance.
