In a medium bowl, combine the ranch dressing, minced garlic, lemon juice, paprika, black pepper, and salt. Mix well to create the marinade.
Add the chicken cubes to the marinade, ensuring they are well-coated. Cover and refrigerate for at least 30 minutes, or up to 2 hours for more intense flavor.
If using wooden skewers, soak them in water for at least 30 minutes to prevent burning during grilling.
Preheat your grill to medium-high heat (about 375°F to 400°F).
Thread the marinated chicken onto skewers, leaving a little space between each piece for even cooking.
Brush the grill grates with olive oil to prevent sticking. Place the skewers on the grill and cook for 10-12 minutes, turning occasionally, until the chicken is cooked through and reaches an internal temperature of 165°F.
Remove the skewers from the grill and let them rest for a few minutes before serving. Enjoy your Ranch Garlic Chicken Skewers hot off the grill!
