Preheat your grill or oven to 400°F (200°C).
In a mixing bowl, combine olive oil, minced garlic, grated Parmesan cheese, salt, black pepper, and dried Italian herbs. Whisk until well combined.
Add the cubed chicken to the bowl, and toss to coat evenly in the marinade. Allow the chicken to marinate for at least 15 minutes.
Thread the marinated chicken pieces onto skewers, leaving a little space between each piece for even cooking.
Place the skewers on the preheated grill and cook for approximately 10-15 minutes, turning occasionally, until the chicken is cooked through (internal temperature of 165°F/75°C).
If baking, arrange the skewers on a baking sheet and bake in the preheated oven for about 15 minutes, flipping halfway through, until the chicken is cooked through.
Remove the skewers from the grill or oven, and let them rest for a few minutes before serving.
Serve the Garlic Parmesan Chicken Skewers with lemon wedges on the side for an added zest.
