The chicken, fruit, and vegetables all roast together in the oven, and they come out golden and caramelized, just the kind of crowd-pleasing dish you'll want for your next dinner party.
Preheat oven to 375 degrees. On a large rimmed baking sheet (or two small ones), toss parsnip, turnip, and onions with vinegar, 1 tablespoon oil, and 1/2 teaspoon thyme; season with salt and pepper.
In a small bowl, combine parsley and remaining 1/2 teaspoon thyme; season with salt and pepper. Carefully slide fingers under chicken skin to loosen; spread parsley mixture under and on top of skin. Push vegetables to edges of baking sheet; place chicken pieces in center, and roast 30 minutes.
Meanwhile, in a small bowl, combine honey and remaining tablespoon oil. Remove baking sheet from oven; add pears, and toss with vegetables to combine. Brush top of chicken pieces with honey mixture; roast 30 minutes more or until an instant-read thermometer inserted in thickest part of thigh (avoiding bone) registers 175 degrees. Serve immediately.
