Preheat your oven to 425°F (220°C) and line a large baking sheet with parchment paper.
Pat the chicken thighs completely dry with paper towels to ensure the skin reaches maximum crispiness.
In a small bowl, combine the dried rosemary, thyme, garlic powder, sea salt, and black pepper.
Rub the herb mixture evenly over both sides of the chicken thighs, ensuring some seasoning gets underneath the skin.
Place the chicken on the prepared baking sheet and roast for 15 minutes.
While the chicken is roasting, toss the broccoli florets and sliced carrots with olive oil in a medium bowl.
Remove the baking sheet from the oven, arrange the vegetables in a single layer around the chicken, and return to the oven.
Roast for an additional 20-25 minutes until the chicken reaches an internal temperature of 165°F and the skin is golden brown.
Allow the chicken to rest for 5 minutes before serving to ensure the meat remains juicy.
