Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Peel the carrots and slice them into 1/2-inch thick rounds; cut the chicken breast into 1-inch bite-sized cubes.
In a small bowl, whisk together the extra virgin olive oil, maple syrup, sea salt, black pepper, garlic powder, and dried thyme until well combined.
Place the chicken and carrots in a large mixing bowl, pour the maple mixture over them, and toss until every piece is thoroughly coated.
Spread the chicken and carrots in a single layer on the prepared baking sheet, ensuring they are not overcrowded to allow for proper roasting.
Roast in the oven for 20 to 25 minutes, tossing the ingredients halfway through the cooking time.
During the last 5 minutes of roasting, sprinkle the chopped pecans over the tray so they become fragrant and toasted.
Remove from the oven once the chicken is cooked through and the carrots are tender and caramelized.
