Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper for easy cleanup.
Peel the sweet potato and carrots, then dice them into uniform 1-inch cubes to ensure they roast evenly.
Finely mince the garlic clove and set it aside for a moment to allow the beneficial compounds to activate.
In a large mixing bowl, combine the chicken breast, diced sweet potatoes, and carrots.
Drizzle the olive oil over the mixture, then sprinkle in the turmeric, dried rosemary, dried thyme, sea salt, black pepper, and minced garlic.
Toss everything thoroughly with your hands or a large spoon until the chicken and vegetables are evenly coated in the golden herb mixture.
Spread the ingredients in a single layer on the prepared baking sheet, making sure not to overcrowd the pan so the vegetables can crisp up.
Roast for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F and the root vegetables are fork-tender and slightly browned.
Remove from the oven and let the chicken rest for 5 minutes before slicing to ensure it stays juicy and flavorful.
