Creating Grilled Cowboy Butter Chicken Skewers is a straightforward process. Follow these steps for mouthwatering results:

1. Soak Skewers: If using wooden skewers, soak them in water for at least 30 minutes to prevent burning on the grill.
2. Prepare the Marinade: In a mixing bowl, combine softened butter, olive oil, minced garlic, chopped parsley, smoked paprika, chili powder, salt, pepper, and lemon juice. Mix well until combined.
3. Add Chicken: Place the chicken pieces in a large bowl or zip-top bag. Pour ¾ of the cowboy butter marinade over the chicken. Reserve the remaining marinade for basting.
4. Marinate: Seal the bag or cover the bowl and marinate the chicken in the refrigerator for at least 30 minutes.
5. Thread Skewers: Preheat your grill to medium-high heat. Thread the marinated chicken pieces onto the prepped skewers, alternating with bell pepper and red onion if using.
6. Grill the Skewers: Place the skewers on the hot grill. Cook for 15-20 minutes, turning occasionally, until the chicken is cooked through and has nice grill marks.
7. Baste: During the last few minutes of grilling, brush the skewers with the reserved cowboy butter marinade for extra flavor.
8. Check for Doneness: Ensure the chicken reaches an internal temperature of 165°F (75°C) before removing from the grill.
9. Serve: Remove the skewers from the grill and let them rest for a couple of minutes before serving.
