Can roasted eggplant be left out overnight still in the skin overnight?

It's not recommended to leave roasted eggplant out overnight still in the skin. Eggplant is a perishable vegetable and can become unsafe to eat if left at room temperature for too long. Roasted eggplant is particularly susceptible to spoilage because the cooking process softens the flesh and makes it more vulnerable to bacterial growth.

To ensure food safety, it's best to store roasted eggplant in the refrigerator within two hours of cooking. If you're not planning to eat the eggplant within a couple of days, it's best to freeze it for longer storage. When ready to consume, thaw the eggplant in the refrigerator overnight and reheat it thoroughly before eating.
