Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper.
Wash and cube the red potato into 1-inch pieces, and slice the carrots and parsnips into uniform half-inch rounds.
In a small bowl, whisk together the extra virgin olive oil, minced garlic, chopped rosemary, chopped thyme, sea salt, and black pepper.
Place the chopped vegetables in a large bowl and toss with half of the garlic-herb oil mixture until well coated.
Spread the vegetables in a single layer on the prepared baking sheet, leaving space in the center for the chicken.
Rub the remaining oil mixture over both sides of the chicken breast and place it in the center of the baking sheet.
Roast for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F and the vegetables are tender and golden brown.
Let the chicken rest for 5 minutes before slicing and serving alongside the roasted root vegetables.
