Preheat the oven to 425F.
Peel the parsnips, then cut into evenly sized matchsticks.
Place in a large bowl and toss with the olive oil, salt, and pepper.
Evenly distribute the parsnips on a baking sheet in a single layer, making sure they have a little room on the sides to brown and caramelize.
Roast for about 20-25 minutes, until the parsnips are starting to turn golden brown on the edges. Toss the parsnips to redistribute, then roast for another 10-15 minutes, until tender and golden.
Serve warm and enjoy!
