When cooking, the age-old question of whether to heat the pan or the oil first has plagued chefs and home cooks alike. The answer depends on the type of oil and cookware used. For example, when using olive oil, it is best to start with a cold pan as olive oil has a low smoke point and will burn instantly if added to a hot pan. On the other hand, some cooks prefer to heat the pan first when using oils with higher smoke points, arguing that the appearance of the oil in the pan indicates when the pan has reached the proper temperature. Ultimately, the goal is to have both the pan and the oil hot before adding food to prevent sticking.

| Preventing food from sticking | Heating the pan first and then adding cold oil is a popular method to prevent food from sticking to the pan. However, some cooks prefer heating the pan and oil together as the appearance of the oil can indicate when the pan has reached the right temperature. |
| Pan type | It is recommended to use a heavy-bottomed stainless or aluminum pan with cold oil. Non-stick pans should not be preheated as they can emit unhealthy fumes and ruin the coating. |
| Oil type | Oils with a low smoke point, such as olive oil, sesame oil, or vegetable oil, are better suited for cold pans as they can burn instantly in a hot pan. High smoke point oils like peanut or grapeseed oil are more suitable for hot pans. |
| Food type | Cold food should be brought to room temperature before being added to the pan to avoid cooling down the pan and oil. |
| Safety | Heating a pan without oil prevents the risk of fire. Adding oil to a hot pan can cause spontaneous combustion if left unattended for too long. |

What You'll Learn
Using cold oil in a hot pan can prevent food from sticking
Using cold oil in a hot pan is a popular method to prevent food from sticking. This method is especially useful when sautéing or stir-frying. The idea is to heat the pan first and then add the cold oil, followed by the food almost immediately. This technique works because when you add the oil to a very hot pan, it starts to vaporize, creating a vapour layer that prevents the food from bonding to the pan.
However, it is important to note that this is not the only way to prevent food from sticking. Some cooks prefer to heat the oil along with the pan, as it can be challenging to determine the exact temperature of a pan without oil. Heating the oil and the pan together also helps maintain a consistent temperature, especially when cooking delicate foods like fish.
The type of oil and pan used also play a role in preventing food from sticking. For example, olive oil has a low smoke point and should be added to a cold pan, while peanut oil or grapeseed oil have higher smoke points and can be used with a hot pan. Non-stick pans with Teflon coatings should also be handled with care, as heating them without oil can emit unhealthy fumes and damage the coating.
Additionally, it is essential to ensure that the food is at room temperature before adding it to the pan. Cold food can cool down the pan and oil, potentially impacting the cooking process and leading to sticking.
While using cold oil in a hot pan can be effective, it is not the only factor that determines whether food will stick. The pan's temperature, the type of oil and cookware used, and the food's temperature all play a role in the cooking process and should be considered when aiming to prevent sticking.

Cold oil in a hot pan can reduce the risk of a fire
Cooking oils, such as olive oil, coconut oil, corn oil, and canola oil, are commonly used for baking, frying, and flavoring food. While they enhance the taste of dishes and provide nutrients, they are also highly flammable. Cooking oils can catch fire if overheated, with lower smoke point oils like olive oil being more prone to catching fire.
To prevent a cooking oil fire, it is important to understand the risks associated with using cooking oil in the kitchen. Always monitor the heat, never leave cooking unattended, and keep a fire extinguisher nearby for safety.
When using a non-stick pan with a Teflon coating, you should add the oil to a cold pan. Non-stick pans can emit unhealthy fumes if heated dry, and the heat can also ruin the coating on the pan.
Some cooks prefer to heat the pan first and then add the oil, as the appearance of the oil in the pan can give an indication of when the pan has reached the proper temperature. This method can also help prevent food from sticking to the pan. When oil is added to a very hot pan, it starts to vaporize, creating a vapor layer that prevents the oil from bonding to the pan.
However, adding cold oil to a hot pan can cause splattering and instant fires. To reduce the risk of fire, it is recommended to gradually heat the pan with the oil to avoid temperature disparities. Therefore, cold oil in a hot pan can reduce the risk of a fire if it is heated gradually with the pan rather than added to a very hot pan.

Cold oil in a hot pan is not suitable for cooking steak
While the "hot pan, cold oil" method is a popular way to prevent food from sticking to the pan, it is not suitable for cooking steak.
Firstly, when cooking steak, you want a super-hot pan to achieve a good sear. Adding cold oil to a hot pan will result in the oil heating up almost instantly, but it can be difficult to control the temperature and it may take longer to reach the desired heat. This can lead to the oil smoking excessively or even catching fire, creating an unpleasant smell and potentially hazardous situation.
Secondly, oiling the steak itself, rather than the pan, ensures that the oil is exactly where it needs to be and prevents the steak from sticking to the pan. This method also reduces the amount of oil used, resulting in a less greasy steak that allows the natural flavors of the meat to shine through.
Additionally, when cooking steak, it is important to use an oil with a high smoke point, such as avocado, canola, grapeseed, or peanut oil. These oils can withstand the high temperatures needed to cook steak without burning and imparting a rancid taste.
Finally, when using the "hot pan, cold oil" method, it can be challenging to determine the ideal temperature for cooking steak. The appearance of the oil in the pan can be a helpful indicator of when the pan has reached the proper temperature, but this can be tricky to gauge accurately.
In summary, while the "hot pan, cold oil" technique may work for some dishes, it is not the best approach when cooking steak. To achieve the best results, it is recommended to oil the steak directly, use a high-smoke-point oil, and cook the steak in a super-hot pan to get a good sear.

Cold oil in a hot pan is not suitable for cooking eggs
While cooking eggs, it is not advisable to pour cold oil into a hot pan. The primary reason for using oil is to prevent eggs from sticking to the pan. The amount of oil required depends on the pan's stickiness. A well-seasoned cast-iron pan may not need any oil at all, but a worn-out non-stick pan will likely require a generous amount.
Additionally, oil helps with heat transfer, especially once the egg is no longer in its liquid state and may not be in full contact with the pan. Oil also adds flavour and texture to the dish. For example, olive oil, butter, or bacon grease can be used to fry eggs, each imparting a unique taste.
When frying an egg, it is generally recommended to heat the pan first and then add the oil. The heat setting and the amount of oil depend on the type of oil or fat used. For instance, butter or olive oil should be heated to just under medium heat (300°F/150°C), while other oils and fats should be heated to medium-high (350°F/175°C).
It is worth noting that the technique of starting with a cold pan and gradually increasing the heat has been suggested by some sources to achieve flawless fried eggs with intact yolks and no rubbery whites. However, this method does not allow butter to be used as it won't melt in time, and oil is recommended instead.

Cold oil in a hot pan is not suitable for cooking fish
While cold oil can be used in a hot pan for cooking fish, there are several reasons why this may not be ideal. Firstly, adding cold oil to a hot pan can cause oil splatter, which can be messy and even dangerous. This is especially true when cooking fish, as the moisture released during cooking can increase the amount of splatter. To avoid this, it is recommended to oil the fish itself rather than the pan, using just enough oil to keep the fish moist and prevent sticking.
Another issue with using cold oil in a hot pan is the risk of burning or smoking. When cold oil is added to a hot pan, it can heat up too quickly and burn, affecting the taste of the dish. This is particularly true for oils with lower smoke points, such as unrefined oils. To prevent this, it is generally advised to heat the oil in the pan until it reaches the desired temperature before adding the fish.
Additionally, using cold oil in a hot pan can affect the cooking process of the fish. When the fish is added to the pan, the temperature of the oil will drop, and it may take longer to reach the ideal cooking temperature. This can impact the texture and taste of the fish, especially if it is cooked at a lower temperature than recommended.
Furthermore, the type of oil used is important when cooking fish. Different oils have different smoke points and flavours that can affect the final dish. For example, extra-virgin olive oil has a clean taste and is a healthy option for grilling, broiling, or baking fish. Peanut oil, on the other hand, has a high smoke point and is suitable for frying Asian dishes or any recipe where its flavour will complement the dish.
Lastly, the amount of oil used when cooking fish is crucial. Some fish, such as salmon, trout, and tuna, are naturally oily, so using too much oil can make the dish greasy. It is recommended to use just enough oil to prevent the fish from sticking to the pan and to ensure even cooking.
