Place the oven rack in the middle and preheat the oven to 400° F/200° C.

In the medium bowl, stir together the olive oil, kosher salt, and your chosen spice mix. Toss with the sliced parsnips, then lay the parsnip slices on the prepared baking sheet, spreading them out.

Bake in the preheated oven until chips are golden brown and crispy, about 10 to 15 minutes. Removed from the oven and transfer chips to a plate lined with a paper towel to drain, then serve
