Creating this delightful Greek Sheet-Pan Chicken is easy and straightforward. Follow these step-by-step instructions:

1. Preheat Oven: Preheat your oven to 425°F (220°C).
2. Prepare Marinade: In a large bowl, whisk together the olive oil, lemon juice and zest, minced garlic, oregano, thyme, salt, and pepper.
3. Marinate Chicken: Add the chicken thighs to the bowl, ensuring they are well-coated with the marinade. Allow to marinate for at least 20 minutes, or up to 4 hours for more flavor.
4. Prepare Vegetables: While the chicken marinates, prepare the vegetables by cutting the cherry tomatoes, bell peppers, red onion, and olives.
5. Arrange on Sheet Pan: Line a large baking sheet with parchment paper. Place the marinated chicken thighs in the center and surround them with the prepared vegetables.
6. Roast in Oven: Place the sheet pan in the preheated oven and roast for 30-35 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (75°C). The vegetables should be tender and slightly caramelized.
7. Check for Doneness: Ensure the chicken skin is crispy and golden brown. If needed, you can broil for an additional 2-3 minutes for extra crispiness.
8. Garnish: Remove the sheet pan from the oven and sprinkle fresh parsley over the top before serving.

With these steps, you will create a beautiful and delicious Greek Sheet-Pan Chicken that will impress your family or guests!
