To cut parsnips: Trim tops and bottoms; peel, and slice in half crosswise to separate thick and narrow parts. Halve or quarter thick parts lengthwise, until all parsnip pieces are roughly the same size (this ensures even cooking).
- 2 1/2 pounds medium parsnips
- 2 tablespoons olive oil
- Coarse salt and ground pepper
Preheat oven to 450 degrees. Peel 2 1/2 pounds medium parsnips; cut as directed above.
On two large rimmed baking sheets, toss parsnips with oil; season with coarse salt and ground pepper. Spread in a single layer.
Roast until tender and golden brown, 25 to 30 minutes, rotating baking sheets and tossing parsnips halfway through baking time.
