Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Peel the carrots and slice them into 1/2-inch thick rounds or diagonal coins to ensure even roasting.
Place the chicken breast and sliced carrots in a large mixing bowl.
Drizzle with the extra virgin olive oil and lemon juice, then sprinkle with rosemary, thyme, garlic powder, sea salt, and black pepper.
Toss everything together until the chicken and carrots are thoroughly and evenly coated with the herb mixture.
Spread the chicken and carrots onto the prepared baking sheet in a single layer, ensuring they are not overcrowded.
Roast in the center of the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the carrots are tender and slightly caramelized.
Remove from the oven and let the chicken rest for 5 minutes before slicing to keep it juicy.
Serve the sliced chicken alongside the roasted carrots and enjoy immediately.
