Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Peel the carrots and slice them into 1/2-inch thick rounds on a diagonal for more surface area.
Pat the chicken breast dry with a paper towel and season both sides evenly with the sea salt, black pepper, and garlic powder.
In a small bowl, toss the sliced carrots with the extra virgin olive oil and a pinch of salt until well coated.
Place the chicken breast and the carrots on the prepared baking sheet, ensuring they are in a single layer and not overcrowded.
Roast in the center of the oven for 20 minutes, or until the chicken reaches an internal temperature of 165°F.
While the chicken and carrots roast, melt the ghee in a small saucepan over low heat and whisk in the maple syrup until combined.
Remove the baking sheet from the oven. Transfer the chicken to a plate to rest, covered loosely with foil.
Drizzle the maple-ghee mixture over the carrots and toss them directly on the pan to coat thoroughly.
Return the carrots to the oven for an additional 5-7 minutes until the glaze is bubbling and the carrots are deeply caramelized.
Serve the roasted chicken alongside the glazed carrots and garnish the entire plate with fresh thyme leaves.
