1. The Truth About Refrigerating Hot Food
For years, an old wives’ tale has cautioned against putting hot food in the refrigerator. But is there any truth to this myth? The short answer is no. The United States Department of Agriculture (USDA) and other food safety agencies state clearly that placing hot food in the refrigerator is safe and often recommended, especially when properly portioned. This practice helps prevent the growth of harmful bacteria, which can thrive when food remains at room temperature for extended periods. However, to make sure food is stored safely, there are some guidelines to follow.
1.1. Debunking the Icebox Myth
The misconception about not putting hot food in the fridge originated from the days of the icebox, a predecessor to the modern refrigerator. Iceboxes used large blocks of ice to keep food cool. Placing hot food inside would cause the ice to melt faster, reducing the icebox’s efficiency and requiring frequent ice replacement. Helen Peavitt, a social historian and author of “Refrigerator: The Story of Cool in the Kitchen,” explains that iceboxes were essentially insulated boxes, and adding heat was counterproductive.
1.2. Modern Refrigerators: A Technological Leap
Modern refrigerators are equipped with advanced cooling systems, including chemical refrigerants and evaporator fans, making them far more efficient than their historical counterparts. These systems can handle warm food without significant disruption, maintaining a consistent temperature to keep other items safe.

2. Safe Practices for Refrigerating Hot Food
To safely refrigerate hot food, follow these steps to minimize any potential risks.
2.1. Portioning Food
Dividing hot food into smaller portions is essential for rapid cooling. Large quantities of food take longer to cool, increasing the risk of bacterial growth. Carve large roasts such as turkey or ham into smaller pieces before refrigerating. For soups, stews, and casseroles, transfer them to shallow containers no more than two inches deep. This allows for quicker cooling, reducing the time food spends in the danger zone (between 40°F and 140°F) where bacteria multiply rapidly.

2.2. Proper Containers
Using the right containers can also facilitate faster cooling. Shallow containers maximize surface area, allowing heat to dissipate more quickly. Cover the containers loosely at first to allow steam to escape, which also speeds up the cooling process. Once the food has cooled slightly, you can seal the containers tightly.
2.3. Time and Temperature Guidelines
The Food and Drug Administration (FDA) recommends refrigerating perishable foods within two hours of cooking or removing them from heat. If the ambient temperature is above 90°F (such as during a summer picnic), refrigerate food within one hour. These guidelines help prevent bacterial growth, keeping your food safe to eat. Ensure that there is enough space for cold air to circulate around the containers in the refrigerator.
2.4. Assisting the Cooling Process
To help your refrigerator handle the heat load efficiently, consider some proactive measures. Stir the food occasionally to distribute heat more evenly. Place the container in an ice water bath to accelerate cooling before refrigerating. This involves setting the pot or container of hot food in a larger bowl filled with ice water.
2.5. Maintaining Optimal Refrigerator Temperature
Keep your refrigerator at the correct temperature to ensure food safety. The ideal temperature is 40°F (4°C) or below. Use an appliance thermometer to monitor the temperature, as built-in thermometers may not always be accurate. The freezer should be kept at 0°F (-18°C). Regular monitoring helps maintain the refrigerator’s efficiency and protects your food from spoilage.
3. Freezing Hot Food: Best Practices
While refrigerating hot food is generally safe, freezing requires additional considerations.
3.1. Cooling Before Freezing
Ideally, food should be cooled before freezing. Rapid freezing results in smaller ice crystals, which cause less damage to the food’s structure. This helps maintain the texture and quality of the food after thawing, according to the USDA. Meat and seafood stay juicier, fruits and vegetables remain more intact, and creamy emulsions are less likely to separate.
3.2. Icing Down Food
Before placing food in the freezer, ice it down or refrigerate it first to lower the temperature. This step is crucial for preserving the food’s quality. When freezing liquids, leave adequate space at the top of the container to allow for expansion as the liquid freezes. Kantha Shelke, a senior lecturer of food safety regulations at Johns Hopkins University, advises leaving an inch of space for pint-size containers and an inch and a half for quart-size containers or larger. Solids should also have at least half an inch of space.
3.3. Freezing in Batches
If you have a significant quantity of food, freeze it in batches. This prevents overloading your freezer, which could raise the temperature and affect the freezing process. Place the smaller portions strategically to maximize contact with the cold surfaces.
4. Choosing the Right Containers for Fridge and Freezer Storage
The type of container you use can significantly impact the safety and quality of your stored food.
4.1. Glass Containers
Glass containers, especially tempered glass, are an excellent choice for both the refrigerator and freezer. They do not absorb odors or stains and are safe for reheating in the oven and microwave. Dr. Shelke recommends them for their durability and inert properties. However, glass containers can be heavy and prone to breaking if not handled carefully.
4.2. Silicone Bags
Silicone bags are a lightweight and flexible alternative to glass. They are not fragile, making them a good option for freezer storage. However, silicone can be tricky to clean and may retain odors. To combat this, soak silicone bags in a mixture of baking soda and water, or use lemon juice to remove stubborn smells.
4.3. Aluminum Foil and Freezer Paper
Aluminum foil and freezer paper are handy for storing irregularly shaped items like casseroles and meats. They provide a good barrier against moisture and air, preventing freezer burn. However, they are not suitable for liquids and may not be as environmentally friendly as reusable options.
4.4. Avoiding Plastic Containers
Avoid putting hot food directly into plastic containers, as heat can cause harmful chemicals like BPA, phthalates, and potentially PFAS to leach into the food. This is especially true for plastics that degrade over time with repeated use, particularly when in contact with acidic or oily foods. Single-use plastics like takeout containers and yogurt tubs are not designed for repeated use or heat exposure and should not be used for storing hot foods. Always choose containers labeled as freezer-safe.
4.5. Additional Tips for Safe Container Use
- Labeling: Always label containers with the date of storage to keep track of how long the food has been stored.
- Sealing: Make sure containers are properly sealed to prevent air exposure and freezer burn.
- Stacking: Organize your fridge and freezer by stacking containers efficiently to maximize space and airflow.
5. Cooling Food Outdoors: When Is It Safe?
Cooling food outdoors can be a temporary measure, but it requires careful consideration to ensure food safety.
5.1. Temperature Considerations
Betty Yaohua Feng, an associate professor in the Department of Food Science at Purdue University, advises that outdoor cooling should only be used as a temporary measure rather than a substitute for proper refrigeration or freezing. Temperatures can be unpredictable, posing a risk to food safety. If you need to cool food outdoors, ensure the temperature remains at or below 40°F.
5.2. Protecting Food from Contaminants
When cooling food outdoors, tightly seal containers to prevent contamination from dust, insects, and wildlife. These can carry pathogens that compromise food safety. Avoid direct sunlight, which can raise the temperature of the food and promote bacterial growth.
5.3. Using Coolers with Ice Packs
A cooler with ice packs is a safer option for outdoor cooling, especially for drinks and less perishable foods. This helps maintain a consistent temperature and protects the food from external elements. Regularly check the temperature inside the cooler to ensure it remains within the safe range.
6. Holiday Food Storage Strategies
Holidays often involve large feasts and plenty of leftovers, making refrigerator space a premium. Planning ahead can help manage the influx of food and ensure everything is stored safely.
6.1. Pre-Holiday Fridge Clean-Out
Before a large event, clear out your refrigerator to make room for leftovers. Helen Peavitt suggests that many items commonly stored in the fridge don’t necessarily need to be there. Unopened pickle jars, ketchup, many fruits and berries, and peanut butter are examples of items that can be stored elsewhere.
6.2. Efficient Space Management
Organize your refrigerator to maximize space and airflow. Use clear containers to easily identify what’s inside and stack items efficiently. Place frequently used items at the front for easy access.
6.3. Utilizing Additional Cooling Options
If you run out of refrigerator space, consider using additional cooling options such as coolers with ice packs or a secondary refrigerator. Ensure these alternative cooling methods maintain a safe temperature for food storage.
