Pans with non-stick coatings should not be heated above 500 degrees Fahrenheit, as this will cause the coating to burn and degrade, releasing toxic vapors that are harmful to humans and fatal to birds. To prevent this, it is important to properly preheat your pan, as a lukewarm pan will draw moisture from the food, causing it to stick. By using a surface thermometer to preheat your pan to the desired temperature, you can ensure consistent cooking results and prevent the pan from getting too hot. While stovetop flames can reach thousands of degrees Fahrenheit, the pan itself rarely exceeds 700 degrees Fahrenheit due to heat loss and the imperfect conductivity of the pan material.

Avoid high heat on non-stick pans
Non-stick pans are not designed to be heated above medium heat. The coating that makes non-stick pans non-stick is only safe when it is intact. When exposed to high heat, the coating can burn and release toxic chemicals, which can be harmful to humans and fatal for animals such as birds. The pans can also be damaged by metal utensils, which can scratch the coating and cause it to flake, releasing microplastics and carcinogens into your food.
To avoid high heat on non-stick pans, it is important to always preheat your pan properly. When a pan is properly preheated, the moisture in the food is drawn away from the surface of the pan, and the fat that you add creates a layer that prevents sticking. A lukewarm pan will cause food to stick, as the moisture will be drawn to the pan.
It is also important to note that non-stick pans should not be left on the heat without anything in them. The coating will be directly exposed to the heat and can burn and release toxic chemicals.
If you are cooking on a stove, only about 30% of the heat generated by the flame will be passed into the pan, and the heat will be dissipated into the surrounding environment, especially if there is food in the pan. Therefore, it is unlikely that your pan will reach temperatures above 500 degrees Fahrenheit, even if your stove is set to a higher temperature.
However, it is still important to be cautious and avoid heating your non-stick pan above 450 degrees Fahrenheit, as some degradation of the non-stick coating can occur at temperatures above 400 degrees. If you need to cook at higher temperatures, it is recommended to use a stainless steel or cast iron pan instead.

Use a thermometer to monitor temperature
While stovetop flames can reach temperatures in the thousands of degrees, the pan itself will not get that hot. A lot of heat energy is lost in the air, and metals are not perfect conductors of heat. If you leave a pan on the highest setting for 15-20 minutes, it will probably get to around 700°F or so. This kind of temperature is only useful if you are trying to hard-sear cuts of meat like steaks.
To prevent your pan from exceeding 500°F, you should use a thermometer to monitor the temperature. You can purchase a surface thermometer to place in the centre of your pan. This will allow you to accurately gauge the temperature of your pan and adjust the heat source accordingly.
It is important to note that different types of pans have different temperature limits. For example, PTFE-based non-stick pans should not be heated above 500°F as the coating may degrade and release toxic vapours. Cast iron pans, on the other hand, can handle extreme heat but are sensitive to rapid temperature changes, which can cause cracking.
Additionally, the type of stovetop you use will also affect the temperature of your pan. Electric stovetops, for instance, can easily overshoot the desired temperature, so it is important to turn down the dial once your pan has reached the desired temperature.
By using a thermometer to monitor the temperature of your pan, you can prevent it from exceeding 500°F and potentially damaging your cookware or creating unsafe cooking conditions.

Preheat pans properly
Properly preheating a pan is an important step in the cooking process. It can stop food from sticking to the pan and ensure consistent cooking. Here are some tips to preheat pans properly:
First, it is important to understand the type of pan being used. Different pans have different heat tolerances and heat distribution properties. For example, cast iron pans hold heat well but do not distribute it evenly, so they should be preheated for a minimum of 10 minutes on the stovetop, starting with low heat and gradually increasing the temperature while rotating the pan to prevent hotspots. On the other hand, non-stick pans with Teflon coatings should not be heated above 500 degrees Fahrenheit or left empty on high heat for extended periods, as this can damage the non-stick surface, release toxins, and cause warping. Stainless steel pans are durable and efficient at evenly distributing heat, making them suitable for most cooking tasks except frying eggs, which are better cooked in non-stick pans.
Once the appropriate pan for the task is selected, the next step is to preheat the pan properly. This usually involves heating the pan for a sufficient amount of time, typically between 5 to 10 minutes, depending on the pan's material and your stove's heat settings. It is important to note that the pan should be heated without any oil, butter, or food items until it reaches the desired temperature. Adding oil or butter can be done carefully towards the end of the preheating process or after the pan has reached the desired temperature. The oil can be used to re-season" the surface of the pan, especially in the case of cast iron pans.
To determine if the pan is properly preheated, one can use a surface thermometer placed in the center of the pan. Additionally, for non-stick pans, one can observe the oil added to the pan; a light shimmering or smoking of the oil indicates that the pan is preheated.

Avoid rapid temperature changes
Pans with non-stick coatings should not be heated over 500°F. This is because non-stick coatings tend to burn at temperatures between 350-400°F. Degradation of the coating can happen at lower temperatures, but at 500°F or above, it is both certain and swift. At high temperatures, the coating undergoes pyrolysis, during which some of its fluorine compounds vaporize. This process is harmful to your health and can be fatal to birds.
To avoid your pan from reaching temperatures of 500°F and above, you should avoid rapid temperature changes. This is especially important if you are using a cast-iron pan, as it can crack if exposed to temperature shocks. For example, do not preheat your pan to 500°F and then add something frozen to it.
To regulate the temperature of your pan, you should turn down the dial on your burner once the desired temperature has been reached. This is because electric elements can easily overshoot the desired temperature. You should also avoid leaving your pan on the highest setting for an extended period of time, as this will cause the temperature to continue climbing.
Additionally, you can prevent your pan from reaching such high temperatures by adding food or liquids to it. As these are colder than the pan, they will immediately reduce the pan's temperature. This effect is especially pronounced if you add water-based liquids, as they can only heat up to their boiling point of 212°F.
To accurately gauge the temperature of your pan, you should use a thermometer.

Use a stove instead of an oven for non-stick pans
While a stove's flame can burn at around 3500°F, the pan itself won't get that hot because heat energy is lost in the air and metals are not perfect conductors of heat. Pans with non-stick coatings that shouldn't be heated over 500°F should not be heated empty or with high heat in general. This is because, in an oven, every surface of the pan is exposed to the heat and the coatings tend to burn over 350-400°F. On a stove, the coating isn't directly exposed to the heat as the base aluminium acts as a buffer.
Therefore, if you want to use a non-stick pan, it is better to use a stove instead of an oven. To stop a pan from getting too hot, you can also preheat your pan properly. When a pan is properly preheated, the moisture in the food is drawn away from the surface of the pan, and the fat that you add to the pan makes it easier for your food to slide around.
It is important to note that not all non-stick pans are suitable for high temperatures. Teflon, for example, emits threatening fumes if heated above 500°F, and ceramic coatings lose their non-stick properties if exposed to high heat. To avoid this, you can check the manufacturer's website or label to see the recommended maximum temperature for your non-stick pan.

Frequently asked questions
To prevent your pan from exceeding 500 degrees Fahrenheit, you should avoid leaving it on the highest setting for an extended period. After preheating your pan, turn down the dial on the burner to regulate the temperature. Additionally, avoid using high heat on non-stick pans, as it can damage the coating.
Many pans have temperature limits, such as "oven-safe up to 500 degrees Fahrenheit," because higher temperatures can damage the pan's coating or cause it to stick. PTFE-based non-stick pans, for example, can degrade at temperatures above 400 degrees Fahrenheit and will certainly be damaged at 500 degrees Fahrenheit or higher.
The suggested temperatures for your cooking surface depend on your personal preferences and the type of food being prepared. For searing, sautéing, and boiling, a temperature range of 425 to 450 degrees Fahrenheit is often sufficient. Higher temperatures may be necessary for wok cooking.
To accurately determine the temperature of your pan, it is recommended to use a thermometer, such as an infrared thermometer or a surface thermometer. This allows you to incrementally adjust the heat and gain a better understanding of your stove's performance.
If you require cooking temperatures above 500 degrees Fahrenheit, consider using stainless steel or cast iron pans. Cast iron, in particular, can withstand extreme heat but is sensitive to rapid temperature changes, so caution is advised during preheating and the introduction of colder food items.
