There are several factors to consider when deciding whether to put a pan in the fridge. Firstly, it is essential to ensure that the pan is made of a suitable material, as certain materials like non-stick coatings and cast iron may be damaged by the cold temperatures. Secondly, the size of the pan and the amount of food it contains are important considerations. Large pans filled with hot food can raise the overall temperature of the fridge, creating an environment conducive to bacterial growth and food spoilage. Therefore, it is generally recommended to transfer food to containers specifically designed for refrigeration, allowing for quicker cooling and safer storage. However, some sources suggest that placing hot pans in the fridge is acceptable as long as they are not too large and the food is not left out for extended periods, as this can also lead to bacterial growth.

What You'll Learn
Pans with non-stick coatings should not go in the fridge
While it may be tempting to store your cooked food in the pan you prepared it in, it is not always advisable, especially if the pan has a non-stick coating.
Firstly, pans with non-stick coatings are not designed for refrigerator storage. The non-stick surface is sensitive to cold temperatures and prone to wear and tear when exposed to them. This can cause the coating to lose its effectiveness over time. Secondly, fridges are crowded spaces, and non-stick pans can easily get scratched by other items or utensils. Any damage to the coating will reduce the pan's non-stick properties.
Additionally, pots and pans don't have airtight lids, so even if you cover the pan with a lid, the contents won't be properly sealed. This could result in cross-contamination and create a moist environment, which is ideal for the growth of bacteria.
Therefore, it is recommended to transfer your cooked food to a container meant for refrigeration, such as airtight glass or plastic containers, instead of storing it directly in the pan. These materials are specifically designed for refrigerating food and do not pose any risk of damage.
Furthermore, placing large batches of hot food in the fridge can raise the appliance's temperature, creating a "danger zone" for bacterial growth. To avoid this, divide large amounts of food into smaller or shallow storage containers, and consider using an ice bath or cold water to help the food cool more quickly.

Cast iron pans can rust in the fridge
While cast iron pans can be placed in the fridge, it is not recommended for long periods. The biggest risk in placing cast iron in the fridge is the damage that can be inflicted upon the cast iron.
Firstly, placing cast iron skillets in the fridge for long periods can add unwanted moisture to the skillet, which will make it rust. To prevent this, cast iron pans should be stored with the lids off, especially in humid weather. Paper towels can also be placed inside the pans to absorb any moisture that might form while they are stored.
Secondly, cast iron should never be placed in the fridge while hot, as this will cause the skillet to crack due to temperature shock. The same applies when removing a cast iron pan from the fridge and placing it on a hot surface. It is recommended to let the skillet come to room temperature first.
Thirdly, if the food you are storing in the cast iron is acidic, a negative chemical reaction will occur between the iron and the acid. This can ruin the taste of the food and damage the seasoning of the pan.
Therefore, while it is possible to temporarily store food in a cast iron pan in the fridge, it is not advisable to do so for long periods due to the risk of rust, cracking, and damage to the seasoning of the pan.

Hot pans can increase the fridge temperature, causing food spoilage
Placing hot pans in the fridge can increase the internal temperature, creating an environment for harmful bacteria to grow and cause food spoilage. Food safety specialists recommend cooling food as quickly as possible to prevent spoilage and the growth of foodborne illnesses.
Hot pans can raise the ambient temperature of the fridge, pushing it into the "danger zone". Fridge temperatures should be maintained below 40°F (4°C) to prevent bacterial growth. Placing hot pans in the fridge can slow down the cooling process, allowing bacteria to thrive.
To avoid this issue, it is advisable to let the food cool down before placing it in the refrigerator. An hour of cooling is usually sufficient. For quicker cooling, the food can be transferred to smaller containers and placed in an ice bath or under cold running water.
Additionally, some types of pans are not suitable for refrigerator storage due to the risk of damage or metal contamination. Non-stick pans, for example, can have their coating degraded by cold temperatures, reducing their non-stick properties. Cast iron pans are also prone to rust when exposed to moisture in the fridge.
Therefore, it is recommended to transfer food to safe vessels, such as airtight glass or plastic containers, specifically designed for refrigeration, instead of storing food directly in pans.

Metal pans may contaminate acidic foods
To avoid these issues, it is recommended to transfer food from metal pans to separate containers designed for refrigeration, such as airtight glass or plastic containers. These materials are specifically designed for storing food and do not pose the same risks as metal pans.
Additionally, it is important to note that placing hot food in metal pans directly into the fridge can also be problematic. While it is generally safe to put hot food in the fridge, it can raise the internal temperature, creating an ideal environment for bacterial growth. Therefore, it is advised to let the food cool down before placing it in the refrigerator or using an ice bath to speed up the cooling process.
By following these guidelines, you can help ensure the safety and quality of your stored food while also maintaining the condition of your metal pans.

Pans don't have airtight lids, which can cause cross-contamination
While it is generally safe to put a pan in the fridge, it is important to consider the potential risks associated with doing so. One concern is the possibility of cross-contamination, which can occur when pans with loose lids are placed in the refrigerator.
Cross-contamination is the transfer of harmful bacteria, allergens, chemicals, or physical objects from one source to another, rendering the contaminated food unsafe to consume. This can happen when food is not properly covered or stored correctly in the fridge. For example, if juices from raw meat drip onto other foods, it can contaminate them with harmful bacteria, leading to food poisoning.
Pans often have loose-fitting lids or no lids at all, which can increase the risk of cross-contamination. When storing food in pans in the fridge, it is crucial to ensure that the pans are properly covered to prevent spillage or leakage. Using plastic wrap or aluminium foil to cover the pans can help prevent spills and reduce the risk of cross-contamination.
Additionally, it is important to follow safe food storage practices. Store raw animal products on the bottom shelves of the fridge, with ready-to-eat foods placed above them. This prevents any potential drips or spills from contaminating other foods. Always keep food covered, and ensure that containers have effective lids or seals to prevent leakage. Regularly clean and sanitise the fridge, and promptly clean up any spills to maintain a safe food storage environment.
By taking these precautions and ensuring that pans are properly covered and stored correctly, you can reduce the risk of cross-contamination and maintain food safety even when storing food in pans in the refrigerator.
