FAQ
Can I use bone-in chicken instead?
Yes, but increase cooking time to 45-50 minutes. Bone-in breasts and thighs add flavor and stay juicier than boneless cuts.
What if my potatoes finish before the chicken is done?
Potatoes and chicken should finish together at 33-35 minutes. If potatoes are tender early, check chicken temp. If chicken needs more time, potatoes will stay warm; if undercooked, cover pan loosely with foil to prevent browning.
How long can I keep leftovers and can I freeze them?
Refrigerate up to 3 days. Freezing is not recommended; texture becomes mushy when thawed. Reheat stovetop or oven instead.
