Creating Garlic Parmesan Chicken Skewers is straightforward if you follow these step-by-step instructions:

1. Prepare the Chicken: Cut the boneless chicken breasts into 1-inch cubes for even cooking.
2. Make the Marinade: In a bowl, whisk together olive oil, minced garlic, Parmesan cheese, parsley, salt, pepper, and paprika (if using).
3. Marinate the Chicken: Add the chicken cubes to the marinade and ensure they are fully coated. Cover and refrigerate for at least 15 minutes. For maximum flavor, marinate for up to 2 hours.
4. Preheat the Grill: Heat your grill to medium-high heat. If using bamboo skewers, soak them in water for 30 minutes beforehand to prevent burning.
5. Skewer the Chicken: Thread the marinated chicken onto skewers, leaving a bit of space between each piece for even cooking.
6. Grill the Skewers: Place the skewers on the grill. Cook for about 10-12 minutes, turning occasionally until the chicken is fully cooked and no longer pink in the center. The internal temperature should reach 165°F (75°C).
7. Serve: Remove the skewers from the grill. Optionally, sprinkle additional Parmesan and fresh parsley before serving.
