Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Pat the chicken breasts dry with a paper towel and slice them into 1-inch thick strips to ensure even cooking.
Peel the carrots and slice them diagonally into 1/2-inch thick coins to provide more surface area for the glaze.
In a large mixing bowl, whisk together the olive oil, maple syrup, sea salt, black pepper, and garlic powder.
Add the chicken strips and carrots to the bowl, tossing thoroughly until every piece is coated in the maple mixture.
Spread the mixture in a single layer on the prepared baking sheet, ensuring nothing is overcrowded so they roast rather than steam.
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 garnish with fresh thyme leaves before serving warm.
