Preheat your oven to 400°F (200°C) and line a large sheet pan with parchment paper for easy cleanup.
In a small mixing bowl, whisk together the extra virgin olive oil, fresh lemon juice, minced garlic, dried oregano, dried thyme, sea salt, and black pepper.
Place the chicken breast, halved baby potatoes, broccoli florets, sliced red bell pepper, and sliced zucchini onto the prepared sheet pan.
Drizzle the lemon-herb mixture over the chicken and vegetables, using your hands or tongs to toss everything until thoroughly and evenly coated.
Spread the ingredients out into a single layer, ensuring that the chicken pieces are not crowded so they roast rather than steam.
Bake in the center of the oven for 20 to 25 minutes, or until the chicken reaches an internal temperature of 165°F and the potatoes are fork-tender.
Switch the oven to broil for the last 2 minutes if you prefer a more golden-brown color on the vegetables.
Remove from the oven and let the chicken rest for 5 minutes before slicing and serving.
