Preheat your oven to 425 degrees and prep a baking sheet with parchment paper.
Wash parsnips and chop the ends off, as well as any brown bits.
Peel the parsnips with a vegetable peeler. Cut the parsnips into evenly-sized pieces. For the wider end, cut the parsnip in half before chopping into pieces.
Place parsnips in a mixing bowl. Drizzle in olive oil and sprinkle in seasonings. Use a spoon to toss parsnip pieces in oil and seasonings.
Lay seasoned parsnip slices in a single layer on a parchment paper-lined baking sheet. Roast for 40 minutes or until they are fork-tender. If 40 minutes is not long enough to tenderize the parsnips, cook for another 5-10 minutes and check again. They should be pierced easily with a fork
When done, remove from oven and move to a serving bowl.
