How much longer should you cook chicken if lower the cooking temperature from 450 to 400?

You can't just calculate how much longer to cook chicken by simply lowering the temperature. Here's why:

* Different Cuts, Different Times: The size and thickness of the chicken piece drastically affects cooking time. A whole chicken takes much longer than chicken breasts.

* Internal Temperature is Key: The safest way to cook chicken is to make sure it reaches an internal temperature of 165°F (74°C) for whole chicken and 165°F (74°C) for breasts and thighs. This ensures it's cooked through and safe to eat.

* Even Heating: Lowering the temperature helps ensure more even cooking, preventing the outside from burning before the inside is cooked.

Instead of just adding time, here's what to do:

1. Check Your Recipe: Your recipe should give you a time range for your specific cut of chicken at 400°F.

2. Use a Meat Thermometer: This is the most reliable way to ensure your chicken is cooked through. Insert the thermometer into the thickest part of the chicken, making sure it doesn't touch bone.

3. Be Patient: Lowering the temperature will likely mean a longer cooking time. Don't rush the process!

Remember: It's better to cook chicken a little longer than to risk undercooking. Always use a meat thermometer to ensure food safety.
