Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Peel and slice the carrots into 1/2-inch thick rounds, then toss them in a bowl with 0.5 tbsp olive oil, maple syrup, and half of the salt and pepper.
Spread the carrots in a single layer on the baking sheet and roast for 20-25 minutes, tossing halfway through, until tender and caramelized.
While the carrots roast, season the chicken breast evenly on both sides with garlic powder and the remaining salt and pepper.
Heat the remaining 0.5 tbsp olive oil in a cast-iron or stainless steel skillet over medium-high heat.
Place the chicken in the skillet and sear for 6-7 minutes per side until golden brown and the internal temperature reaches 165°F.
Remove the chicken from the heat and let it rest for 3 minutes to keep it juicy before slicing.
Plate the chicken alongside the glazed carrots and garnish with chopped fresh parsley for a bright finish.
