Preheat oven to 450°. Whisk together first 3 ingredients in a bowl. Add parsnip and next 4 ingredients; toss until vegetables are well coated. Add salt and pepper, and toss again. Place in a single layer on a rimmed baking sheet, and bake at 450° for 15 minutes. Stir vegetables, and bake 15 more minutes or until slightly crisp and golden but tender.
