In a mixing bowl, combine the olive oil, lemon juice, lemon zest, minced garlic, oregano, thyme, salt, and black pepper. Whisk together until well blended. This mixture will infuse the chicken with flavor and keep it moist during grilling.

Place the chicken breasts in a resealable plastic bag or a shallow dish. Pour the marinade over the chicken, ensuring each piece is well coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes, or up to 4 hours. Marinating helps to tenderize the meat and enhances the flavor.

Preheat your grill to medium-high heat (about 400°F to 450°F). This temperature is ideal for achieving a nice sear on the chicken while keeping it juicy inside.

Remove the chicken from the marinade and discard the marinade. Place the chicken breasts on the grill. Grill for 6-7 minutes on one side without moving them to get nice grill marks.

Flip the chicken using tongs and grill for an additional 6-7 minutes on the other side. Use a meat thermometer to check for doneness; the internal temperature should reach 165°F.

Once cooked, remove the chicken from the grill and let it rest for 5 minutes. This allows the juices to redistribute, making the chicken more tender. Serve with lemon wedges and your choice of sides.
