Facing a steaming dish that needs refrigeration can be a dilemma. Should you wait for it to cool down at room temperature, risking bacterial growth, or quickly put it in the fridge, potentially warming everything else inside? The answer is more straightforward than you might think. Let’s delve into whether you Can I Put Hot Food In The Refrigerator safely and efficiently.
Despite common misconceptions, the USDA and other food safety agencies advise that hot food can, and often should, be refrigerated immediately, especially when portioned correctly. The key is understanding how modern refrigerators differ from their predecessors and implementing best practices.
The Icebox Legacy: Where Did the Myth Originate?
The fear of putting hot food in the refrigerator stems from the era of the icebox, a 19th-century cooling device. According to Helen Peavitt, a social historian and author of “Refrigerator: The Story of Cool in the Kitchen,” iceboxes were essentially insulated boxes with a block of ice at the bottom. Placing hot food inside would cause the ice to melt faster, requiring frequent replacements to maintain cooling.
Modern refrigerators are much more efficient. They use chemical refrigerants and evaporator fans to circulate cold air, allowing them to rebound more quickly from temperature fluctuations. Nevertheless, smart practices are crucial for optimal performance.
How to Safely Refrigerate Hot Food
To ensure food safety when you can I put hot food in the refrigerator, portioning is key. Dishes like lasagna should be divided into smaller, manageable servings to accelerate cooling.

Experts agree that the safest method for refrigerating hot food is to divide it into smaller portions, allowing for quicker cooling. This involves cutting large roasts like turkey or ham, and separating soups and casseroles into shallow containers no more than two inches deep. Initially, loosely cover these containers to allow steam to escape before sealing them tightly.
The FDA states that it’s generally safe to transfer even piping-hot food directly into the refrigerator if there is ample space for cold air circulation (within two hours maximum, or one hour if the ambient temperature exceeds 90°F). However, be aware that this will increase the refrigerator’s energy consumption, as it works harder to maintain its temperature.
To minimize the strain on your refrigerator, speed up the cooling process by stirring the food occasionally and placing the container in an ice water bath.
Freezing Hot Food: A Different Approach
Ideally, avoid placing hot food directly into the freezer. Rapid freezing results in smaller ice crystals that disrupt the food’s structure less, helping it maintain its texture upon thawing, according to the USDA. This means juicier meat and seafood, more intact fruits and vegetables, and fewer split creamy emulsions.
Therefore, cool food down with an ice bath or a stint in the refrigerator before freezing. When freezing liquids, leave space at the top of the container to allow for expansion during freezing (about an inch for pint-sized containers and 1.5 inches for larger containers). Solids should also have at least half an inch of space.
Choosing the Right Containers
Selecting appropriate containers is crucial for food safety and preservation. While options vary, prioritizing materials that are safe for repeated use and don’t leach chemicals is essential.

The choice of containers matters. Dr. Shelke recommends glass containers, especially tempered glass, as they don’t absorb odors or stains and are safe for reheating. Silicone bags are lightweight and durable, but can be challenging to clean and may retain odors. Aluminum foil and freezer paper are suitable for oddly shaped items.
Avoid putting hot food directly into plastic containers, as they can leach harmful chemicals like BPA, phthalates, and PFAS. Single-use plastics like takeout containers are not designed for repeated use or heat exposure. Always ensure that containers are labeled as freezer-safe.
Outdoor Cooling: When It’s Safe
Cooling food outdoors is possible with caveats. As Dr. Feng from Purdue University notes, outdoor cooling can be a temporary aid, but it’s not a substitute for proper refrigeration. Temperature fluctuations and potential contamination are risks.
If using outdoor cooling, ensure containers are tightly sealed to prevent contamination from dust and wildlife. Avoid direct sunlight and ensure the temperature remains below 40°F. A cooler with ice packs offers a more controlled environment.
Holiday Leftovers: Fridge Management
Managing refrigerator space is crucial, especially during holidays when leftovers abound. Identifying items that don’t require refrigeration can free up valuable space.

For holidays and large gatherings, Ms. Peavitt suggests decluttering your refrigerator beforehand. Many items, such as unopened pickle jars, ketchup, certain fruits, and peanut butter, do not require refrigeration and can be stored elsewhere.
In conclusion, to answer the question can I put hot food in the refrigerator, the answer is yes, provided you follow the proper steps to ensure food safety and refrigerator efficiency. Proper portioning, container selection, and awareness of temperature management are critical to maintaining a safe and efficient kitchen.
