Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into 1-inch cubes and chop the carrots and parsnips into similar-sized half-moons to ensure even cooking.
In a large mixing bowl, combine the chicken, carrots, parsnips, and minced garlic.
Drizzle with extra virgin olive oil and sprinkle with sea salt, black pepper, rosemary, and thyme, tossing thoroughly to coat every piece.
Spread the mixture in a single layer on the prepared baking sheet, ensuring there is space between pieces to allow for proper browning.
Roast for 25-30 minutes, tossing halfway through, until the chicken is cooked through and the vegetables have a beautiful golden crunch.
Remove from the oven and let rest for 3 minutes before serving to keep the chicken juicy.
