Is chicken baked for 30 minutes at 400 degrees fully cooked?

No, baking chicken for 30 minutes at 400 degrees Fahrenheit is not enough time to ensure it's fully cooked.

Here's why:

* Chicken Size and Thickness: The time it takes to cook chicken depends on its size and thickness. A whole chicken will take much longer than chicken breasts.

* Internal Temperature: The USDA recommends cooking chicken to an internal temperature of 165 degrees Fahrenheit for safe consumption.

* Even Cooking: Baking chicken for 30 minutes may not cook it evenly throughout, especially if it's a larger piece.

Here's what you should do:

1. Use a meat thermometer: The most accurate way to tell if chicken is cooked is by using a meat thermometer inserted into the thickest part of the meat.

2. Check the internal temperature: Make sure the internal temperature reaches 165 degrees Fahrenheit before consuming.

3. Cook until done: Continue cooking the chicken until it reaches the safe temperature, even if it takes longer than 30 minutes.

Remember: Undercooked chicken can be dangerous. Always cook chicken to the recommended temperature for safe consumption.
