01 - Preheat oven to 425°F. Line a large sheet pan with parchment paper or lightly grease with cooking spray.
02 - In a large bowl, whisk together olive oil, lemon zest and juice, garlic, oregano, thyme, paprika, salt, and pepper until well combined.
03 - Add chicken breasts to the marinade, turning to coat evenly on all sides. Set aside to marinate while preparing vegetables.
04 - In a separate large bowl, combine potatoes, carrots, bell peppers, onion, and broccoli. Drizzle with olive oil and sprinkle with salt and pepper. Toss until vegetables are evenly coated.
05 - Spread vegetables in a single layer on the prepared sheet pan. Place marinated chicken breasts among the vegetables, ensuring chicken is not overlapping.
06 - Roast for 30-35 minutes until chicken reaches an internal temperature of 165°F and vegetables are tender with lightly browned edges.
07 - Remove from oven and let rest for 3 minutes. Sprinkle with chopped fresh parsley and serve with lemon wedges on the side.
