Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Peel the carrots and slice them diagonally into 1-inch thick pieces to ensure even roasting.
Slice the chicken breast into even 1-inch strips to match the cooking time of the carrots.
In a large mixing bowl, whisk together the olive oil, maple syrup, sea salt, black pepper, and fresh thyme leaves.
Add the chicken and carrots to the bowl, tossing thoroughly until every piece is coated in the glossy glaze.
Spread the mixture in a single layer on the prepared baking sheet, ensuring no pieces are overlapping.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the carrots are tender with caramelized edges.
Remove from the oven and let rest for 3 minutes before serving to allow the glaze to thicken slightly.
