Depending on the weather

Depending heavily on the weather conditions for your area, you can leave cooked collard greens out overnight. The greens must be freshly cooked, in a covered container, and not have come into contact with the sun. Otherwise, you should not eat any collard greens that have been cooked and left at room temperature for over 2 hours.

Understanding why eating something that has been left at room temperature is important, and it all comes down to bacteria. If something has been cooked or boiled, then most bacteria have been destroyed. However, if it is left at room temperature with the sun shining on it, then any type of food can activate the natural bacteria in the food and help it grow to dangerous levels, potentially causing food poisoning.

However, you should leave collard greens that have been cooked for a few minutes in ice water to cool down before freezing. Rapid heating and cooling seals the taste but also prevents bacteria from forming. Be sure that the collard greens you are eating have not been allowed to be the perfect breeding ground for unwanted problems.
