Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Dice the sweet potato into half-inch cubes and break the broccoli into uniform florets to ensure even roasting.
Finely mince the garlic cloves and roughly chop the fresh rosemary and thyme leaves.
Place the chicken breast, sweet potato cubes, and broccoli florets on the prepared baking sheet.
Drizzle the extra virgin olive oil over the chicken and vegetables, then sprinkle with the minced garlic, herbs, salt, and pepper.
Toss the vegetables thoroughly to coat and rub the herb mixture into both sides of the chicken breast.
Spread the ingredients out into a single layer, ensuring the chicken is in the center of the pan.
Roast for 20 to 25 minutes until the chicken reaches an internal temperature of 165°F and the sweet potatoes are tender.
Let the chicken rest for 5 minutes before slicing to ensure the meat remains juicy and flavorful.
