FAQ
Can I use frozen chicken for this recipe?
Yes, but thaw completely first and pat very dry. Frozen chicken will release excess moisture and prevent proper browning.
What if I don't have kitchen shears?
Use a sharp chef's knife or heavy-duty scissors. Work slowly and carefully when cutting through the backbone.
How long will leftovers keep?
Properly stored leftover chicken and vegetables will keep in the refrigerator for 3-4 days or frozen for up to 3 months.
