Creating Grilled Ranch Garlic Parmesan Chicken Skewers is a straightforward process. Follow these steps for a mouthwatering result:

1. Prepare the Chicken: Cut the chicken breasts into bite-sized pieces and set aside.
2. Make the Marinade: In a large bowl, combine buttermilk, ranch seasoning, minced garlic, salt, and pepper. Mix well.
3. Marinate: Add the chicken pieces to the marinade. Cover and refrigerate for at least 30 minutes (or up to a few hours) for maximum flavor.
4. Preheat the Grill: Heat your grill to medium-high.
5. Prepare Skewers: If using wooden skewers, soak them in water for about 30 minutes to prevent burning.
6. Skewer the Chicken: Thread the marinated chicken pieces onto the skewers. Leave some space between pieces for even cooking.
7. Brush with Olive Oil: Lightly brush the skewers with olive oil to prevent sticking.
8. Grill the Skewers: Place the skewers on the grill. Cook for about 10-15 minutes, turning occasionally, until the chicken is cooked through and has grill marks.
9. Add Parmesan: During the last few minutes of grilling, sprinkle grated parmesan evenly over the skewers for a cheesy finish.
10. Check Doneness: Ensure the internal temperature of the chicken reaches 165°F (75°C).
11. Serve and Enjoy: Carefully remove the skewers from the grill and let them rest for a few minutes. This allows the juices to redistribute.
