Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel the carrots and slice them into 1-inch diagonal chunks to ensure even roasting.
In a mixing bowl, whisk together half of the olive oil, the maple syrup, cinnamon, and a pinch of salt.
Toss the carrots in the maple mixture until thoroughly coated, then spread them in a single layer on the prepared baking sheet.
Roast the carrots for 20-25 minutes, tossing halfway through, until they are tender and the edges are beautifully caramelized.
While the carrots roast, season the chicken breast on both sides with the remaining sea salt and black pepper.
Heat the remaining olive oil in a skillet over medium-high heat and sear the chicken for 6-7 minutes per side until the internal temperature reaches 165°F.
Allow the chicken to rest for 5 minutes before slicing and serving alongside the warm, glazed carrots.
