Preheat your oven to 400°F and line a large rimmed baking sheet with parchment paper for easy cleanup.
Peel the carrots and slice them into 1-inch thick diagonal rounds to ensure even roasting.
In a small mixing bowl, whisk together the maple syrup, olive oil, apple cider vinegar, sea salt, black pepper, and dried thyme until well combined.
Place the chicken breast and the sliced carrots on the prepared baking sheet in a single layer.
Brush the maple mixture generously over both the chicken and the carrots, turning them to ensure they are fully coated.
Roast in the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the carrots are tender with caramelized edges.
Remove from the oven and let the chicken rest for 5 minutes before slicing it into strips.
Serve the glazed chicken and carrots over a bed of warm, cooked quinoa, drizzling any remaining pan juices over the top.
