Step 1: Prepare the Marinade

• In a small bowl, whisk together olive oil, minced garlic, lemon zest, lemon juice, chopped thyme, rosemary, parsley, salt, and pepper.

Step 2: Marinate the Chicken

• Place the chicken breasts in a shallow dish or a resealable plastic bag.
• Pour the marinade over the chicken, ensuring each breast is coated evenly.
• Marinate in the refrigerator for at least 30 minutes, or preferably overnight for the flavors to meld.

Step 3: Grill the Chicken

• Preheat your grill to medium-high heat. Remove the chicken from the marinade and discard any excess marinade.
• Grill the chicken breasts for about 6-7 minutes on each side, or until they are cooked through and no longer pink in the center. The internal temperature should reach 165°F (75°C).
• Once cooked, remove the chicken from the grill and let it rest for a few minutes before serving.

Step 4: Serve 

• Slice the grilled chicken breasts and serve hot with your favorite side dishes, such as roasted vegetables or a fresh salad.
