The age-old debate: Do you pack up leftovers immediately after dinner, or let them cool down on the counter for a while? The answer is crucial for food safety. Leaving food out too long encourages harmful bacteria growth, but putting hot food straight into the fridge might warm up the appliance and endanger other foods. Let’s break down How Long To Let Food Cool Before Putting In Fridge.
Understanding the Temperature Danger Zone
Harmful bacterial growth thrives between 41 and 135 degrees F (5 and 57 degrees C). This range is known as the “danger zone” for food. Bacteria multiply rapidly within this temperature range, making food unsafe to eat. Putting large quantities of hot food into the refrigerator can potentially raise the fridge’s temperature into this danger zone. The ideal fridge temperature is below 40 degrees F (4 degrees C). If the fridge temperature rises, it can slow down the cooling process, keeping the food in the danger zone longer.

Is it Safe to Put Hot Food in the Fridge?
Yes, it’s generally safe to put hot food directly into the fridge if needed. If you’re prone to forgetting leftovers or won’t be around to store them later, refrigerating them immediately is the best course of action. Modern refrigerators are designed to handle the heat and cool food quickly.
However, food should never sit at room temperature for more than two hours. If it does, exercise caution and discard the food to prevent foodborne illnesses.
According to Serena Poon, a celebrity chef and nutritionist, “You would be able to place a slightly cooled hot dish into the refrigerator long before you hit the two-hour mark… Most food safety experts would say the sooner you can get your leftovers in the fridge, the better.”
How to Cool Foods Quickly for Refrigeration
While it’s safe to put hot food in the fridge, speeding up the cooling process minimizes the time food spends in the danger zone. Here are some effective methods:
Divide Large Batches: When dealing with large portions of food, such as roasts or stockpots of soup, FoodSafety.gov recommends dividing the food into smaller or shallower storage containers. This increases the surface area, allowing for faster cooling in the refrigerator.
Utilize an Ice Bath: For even quicker cooling, place the smaller containers of food into an ice bath or run them under cold water. The ice bath helps rapidly reduce the temperature of the food before it goes into the refrigerator.
Avoid Coolers for Cooling: Never attempt to cool large quantities of hot food in a cooler. Teresa Baczkowski, RDN, explains, “Most coolers are not designed to cool large amounts of hot food quickly. Also, placing hot food in a cooler may not move the food through the temperature danger zone quickly enough.” Coolers are designed to maintain cold temperatures, not to rapidly cool hot food.
Maximum Time Food Can Stay Outside the Fridge
As a general rule, cooked food should not sit at room temperature for more than 2 hours. If the temperature exceeds 90 degrees F (32 degrees C), the USDA advises that food should not be left out for more than one hour.
Leaving leftovers out for extended periods allows dangerous bacteria to multiply, potentially leading to foodborne illnesses. It’s essential to adhere to these time guidelines to ensure food safety.
The Bottom Line: Refrigerate Food Promptly
You can safely store hot foods in the refrigerator without waiting for them to cool completely. Storing them immediately is preferable to leaving them at room temperature for too long. However, if you’re storing a large amount of hot food, dividing it into smaller, shallow containers and using an ice bath can help it cool more quickly. Remember, prioritizing speed in cooling helps minimize the risk of bacterial growth.
