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 2 tablespoons olive oil, lemon zest and juice, minced garlic, oregano, thyme, paprika, 3/4 teaspoon salt, and 1/2 teaspoon pepper. Add chicken breasts and toss to coat evenly. Let marinate while preparing vegetables.
03 - In a separate bowl, combine baby potatoes, carrots, bell peppers, red onion, and broccoli florets. Drizzle with 2 tablespoons olive oil, 1/2 teaspoon salt, and 1/4 teaspoon pepper. Toss until vegetables are evenly coated.
04 - Spread seasoned vegetables on the prepared sheet pan in a single layer. Nestle marinated chicken breasts among the vegetables, ensuring chicken is not overcrowded for even cooking.
05 - Roast for 30-35 minutes until chicken reaches internal temperature of 165°F and vegetables are tender with lightly browned edges. Check chicken at 25 minutes and rotate pan if needed for even browning.
06 - Remove from oven and let rest for 3 minutes to allow juices to redistribute. Garnish with chopped fresh parsley and serve with lemon wedges on the side.
