In a large mixing bowl, combine the ranch dressing, minced garlic, olive oil, garlic powder, black pepper, and smoked paprika. Whisk until smooth.
Add the cubed chicken to the marinade, ensuring all pieces are well coated. Cover the bowl with plastic wrap and let it marinate in the refrigerator for at least 30 minutes, or up to 2 hours for deeper flavor.
Preheat your grill to medium-high heat. If using wooden skewers, soak them in water for 15-20 minutes to prevent burning.
Thread the marinated chicken onto the skewers, leaving a little space between each piece to allow for even cooking.
Remove the skewers from the marinade and sprinkle the grated Parmesan over the chicken pieces.
Grill the chicken skewers for about 10-12 minutes, turning occasionally, until the chicken is cooked through and reaches an internal temperature of 165°F (75°C).
Once done, remove the skewers from the grill and let them rest for a few minutes.
Before serving, garnish with freshly chopped parsley for a pop of color and added freshness.
Notes
Serve with extra ranch dressing for dipping and lemon wedges for garnish.
