Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Peel the carrots and slice them into 1/2-inch thick rounds on a bias for a beautiful presentation.
In a large mixing bowl, toss the carrots with 0.25 tablespoons of olive oil, sea salt, black pepper, and ground cinnamon until evenly coated.
Spread the carrots in a single layer on the prepared baking sheet and roast for 20 minutes until they begin to soften.
While the carrots are roasting, heat the remaining 0.25 tablespoons of olive oil in a medium skillet over medium-high heat.
Season the chicken breast with a pinch of salt and sear for 6 to 7 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the carrots from the oven, drizzle with the pure maple syrup, and sprinkle the chopped pecans over the top.
Return the carrots to the oven for an additional 5 minutes until the glaze is bubbling and the pecans are fragrant and toasted.
Slice the chicken breast and serve it alongside the glossy glazed carrots, garnishing the entire dish with fresh thyme leaves.
