Creating Sheet Pan Mediterranean Chicken & Zucchini requires just a few simple steps. Follow these instructions for a hassle-free cooking experience:

1. Preheat Oven: Begin by preheating your oven to 400°F (200°C). This ensures your chicken and vegetables roast evenly.

2. Prepare the Chicken: In a large bowl, combine the chicken breasts with olive oil, oregano, thyme, garlic powder, salt, black pepper, and lemon juice. Mix well to ensure the chicken is coated.

3. Slice the Vegetables: While the chicken marinates, slice the zucchinis, bell peppers, and red onion.

4. Arrange on Sheet Pan: On a large baking sheet, place the marinated chicken breasts in the center. Surround them with the sliced vegetables.

5. Roast the Dish: Place the sheet pan in the preheated oven and roast for about 30-35 minutes, or until the chicken reaches an internal temperature of 165°F (75°C) and the vegetables are tender.

6. Garnish: Once cooked, remove the sheet pan from the oven. Sprinkle freshly chopped parsley over everything for a burst of color and flavor.

7. Serve Warm: Let it rest for a few minutes before serving to allow the juices to redistribute in the chicken.

By following these straightforward steps, you’ll create a delicious one-pan meal that showcases all the vibrant flavors of the Mediterranean.
