What is the best practice for storing leftover food?

Storing leftover food in shallow containers is the best practice because it promotes even cooling and reduces the risk of bacterial growth. When food is placed in shallow containers, it has more surface area exposed to the cool air in the refrigerator, allowing it to chill quickly and safely. This is particularly important as food left to cool in large, deep containers can remain at unsafe temperatures for too long, creating ideal conditions for bacteria to multiply.

In addition to promoting safe cooling, shallow containers are easier to stack and organize in the refrigerator, which helps prevent cross-contamination with other foods. This method also makes it easier to reheat only the amount needed, reducing food waste and ensuring that leftovers can be safely consumed within a reasonable timeframe.
