Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel the carrots and slice them into 1/2-inch thick diagonal coins for even roasting.
Cut the chicken breast into 1-inch bite-sized pieces to ensure they cook at the same rate as the carrots.
In a large mixing bowl, whisk together the olive oil, maple syrup, sea salt, black pepper, chopped thyme, and chopped rosemary.
Add the chicken and carrots to the bowl, tossing thoroughly until every piece is well-coated in the maple-herb mixture.
Spread the ingredients in a single layer on the prepared baking sheet, leaving space between pieces to allow for proper browning.
Roast for 20-25 minutes, tossing halfway through, until the chicken is cooked through and the carrots are tender and golden.
Serve immediately while warm, drizzling any concentrated glaze from the pan over the top.
