Can I use chicken breast instead of thighs?
Yes, but thighs stay juicier and more forgiving on the grill. If using breast, cut thinner pieces and watch closely to avoid drying out.
How long should I marinate the chicken?
The recipe doesn't specify, but 2–4 hours in the refrigerator allows the pepperoncini brine and seasonings to penetrate the meat.
Do I need wooden or metal skewers?
Either works. Soak wooden skewers in water for 30 minutes before grilling to prevent charring.
Can this be made ahead?
Yes—marinate the chicken up to 24 hours ahead, then grill and bake just before serving. Store cooked skewers in the pan sauce in the fridge up to 3 days.
What if I don't have pepperoncinis?
Banana peppers or mild jalapeños with their brine work as substitutes, though the flavor will be less tangy.
