In a large mixing bowl, combine the olive oil, lemon juice, lemon zest, minced garlic, chopped thyme, rosemary, parsley, smoked paprika, and a generous pinch of salt and pepper. Whisk thoroughly until the marinade is well mixed.
Add the chicken cubes into the bowl with the marinade, ensuring that each piece is completely coated. Cover the bowl with plastic wrap and allow the chicken to marinate in the refrigerator for a minimum of 1 hour, or up to overnight for an even better infusion of flavors.
Preheat your grill to medium-high heat, allowing it to reach the optimal temperature for grilling.
While the grill is heating, prepare your skewers. Take the marinated chicken and thread the cubes onto the skewers, alternating with the red bell pepper squares and zucchini slices to create a visually appealing arrangement.
Once the grill is ready, carefully place the kabobs on the grill grates. Grill for approximately 10-15 minutes, turning occasionally to ensure even cooking and to achieve those lovely grill marks. Cook until the chicken reaches an internal temperature of 165°F (75°C).
After grilling, remove the kabobs from the grill and let them rest on a platter for a few minutes. This resting period allows the juices to redistribute, ensuring tender chicken.
Notes
Serve on a vibrant platter and garnish with fresh herbs and lemon slices.
