Creating the incredible Sheet Pan Mediterranean Chicken & Zucchini is straightforward, especially with these clear steps:

1. Preheat your oven: Set your oven to 400°F (200°C) to prepare for roasting.
2. Prepare the Marinade: In a large bowl, combine olive oil, lemon juice, garlic, oregano, thyme, paprika, salt, and pepper. Mix well.
3. Marinate Chicken: Add the chicken breasts to the bowl and ensure they are well coated with the marinade. Let them marinate for about 15 minutes if time allows.
4. Prepare Vegetables: While chicken is marinating, chop zucchinis, bell peppers, and onions into bite-sized pieces.
5. Combine Ingredients: On a large sheet pan, add the marinated chicken and arrange the chopped vegetables around it.
6. Toss Vegetables: Drizzle a bit more olive oil over the vegetables and sprinkle with additional salt, pepper, and herbs as desired.
7. Roast in the Oven: Place the sheet pan in the preheated oven and roast for 25-30 minutes until the chicken is cooked through and vegetables are tender.
8. Check for Doneness: Ensure the internal temperature of the chicken reaches 165°F (75°C). If necessary, add additional time for thorough cooking.
9. Garnish: Once out of the oven, garnish the dish with fresh parsley for an added touch of color and flavor.
10. Rest Before Serving: Allow the dish to rest for a few minutes before serving to let the juices settle.

These steps make it easy to prepare this delicious meal, ensuring each element is harmoniously roasted for optimal flavor!
