can you reheat chicken that was left in oven overnight?

Here's why:

* Food safety: Leaving cooked chicken at room temperature for extended periods, even in the oven, is a prime breeding ground for bacteria. This can lead to food poisoning.

* Quality: The chicken will likely dry out and become tough, especially if it was uncovered.

Instead, here are some safer options:

* Refrigerate promptly: After cooking, refrigerate the chicken within two hours (one hour in temperatures above 90°F).

* Reheat properly: Reheat the chicken thoroughly to an internal temperature of 165°F. You can do this in the oven, microwave, or on the stovetop.

* Don't reheat multiple times: Avoid reheating the chicken more than once, as this further increases the risk of bacterial growth.

If you are unsure about the safety of any food, it's always best to err on the side of caution and discard it.
