How to Make Oven Baked Onion Soup Chicken

1. Preheat your oven to 400°F (200°C). Place a cast iron skillet inside while it heats for extra crispy results.

Skin is golden and crispy

Internal temperature reaches 175°F–185°F

7. (Optional) Broil for 2–3 minutes for extra crispy skin watch closely!

8. Let the chicken rest for 5–10 minutes, then spoon the flavorful pan juices over the top before serving.
