Preheat your oven to 400°F (200°C).
On a large sheet pan, spread out the vegetables evenly.
Drizzle olive oil over the vegetables and chicken thighs.
Sprinkle garlic powder, rosemary, thyme, salt, and pepper over everything.
Place the pan in the oven and roast for 30-35 minutes, or until the chicken reaches an internal temperature of 165°F and vegetables are tender.
Serve warm and enjoy this comforting, healthy dish.
