Does hot food need to be cooled before putting in fridge?

It's best to cool hot food to a temperature below 140°F (60°C) before putting it in the fridge. Cooling it partially reduces the strain on your refrigerator and helps maintain the safety of other items inside.
Don't Leave It Out Too Long:
Avoid leaving hot food out at room temperature for an extended period. Ideally, you should begin the cooling process immediately after cooking.
Avoid Thermal Shock:
Allow the hot food to cool on the countertop for a few minutes before transferring it to the fridge. Placing extremely hot containers directly in the fridge can cause thermal shock and potentially damage the appliance.
Conclusion
In summary, hot food does need to be cooled before putting it in the fridge, but it is safe to refrigerate it once it has reached a temperature below 140°F (60°C). Proper cooling practices are essential to prevent bacterial growth, maintain food quality, and ensure food safety. By following these guidelines, you can enjoy delicious, safe, and long-lasting meals while minimizing the risk of foodborne illnesses. Food safety should always be a priority in any kitchen, and understanding the science behind hot food cooling is a crucial step in achieving this goal.
