Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
In a small bowl, whisk together the maple syrup, 1 teaspoon of olive oil, and the Dijon mustard until smooth.
Place the chicken breast and sliced carrots on the prepared baking sheet in a single layer.
Drizzle the remaining 1 teaspoon of olive oil over the chicken and carrots, then season everything evenly with sea salt, black pepper, and fresh thyme.
Roast in the oven for 15 minutes, then carefully remove the tray and brush the maple-mustard glaze over both the chicken and the carrots.
Return the tray to the oven and roast for another 10 to 12 minutes, or until the chicken reaches an internal temperature of 165°F and the carrots are beautifully caramelized.
Let the chicken rest for 5 minutes before slicing, then serve alongside the glazed carrots over a bed of warm cooked quinoa.
