Heating Nonstick Pans: Do's And Don'ts

how to heat a nonstick pan

Nonstick pans are a handy tool for any cook to have, but they can be damaged easily if not used and maintained properly. One of the most common mistakes people make is using nonstick pans over high heat. This is because the nonstick coating is made of a waxy substance that will begin to flake and break down at high temperatures, releasing harmful toxins. To prevent this, it is recommended to use nonstick pans at low or medium heat and to avoid metal utensils and steel wool when cooking and cleaning, as these can scratch or chip the coating.

Use low heat

Nonstick pans are convenient cookware with a special coating that prevents food from sticking to the surface. However, it is important to use low heat when cooking with a nonstick pan to avoid damaging the coating and releasing toxins.

When using a nonstick pan, it is best to stick to low heat. The nonstick coating is made of a waxy substance that can begin to flake and break down at high temperatures. Heating a nonstick pan above 400-500 degrees Fahrenheit can cause the molecules on the coating to break down and release fluorocarbons, which are linked to respiratory illnesses. Therefore, it is recommended to use nonstick pans for cooking foods that require low to medium heat, such as eggs and vegetables.

To ensure you are using the right amount of heat, you can use a surface thermometer to check the temperature of your pan. Place the thermometer in the centre of the pan and turn on the heat. Allow the pan to heat up for 5 to 8 minutes before adding any oil, butter, or food. This gives the pan time to reach the desired temperature and ensures that your food won't stick.

Additionally, when using a nonstick pan, avoid using metal utensils or steel wool for cleaning as they can scratch or damage the coating. Instead, opt for wooden or silicone utensils and always hand wash your nonstick pans to prolong their lifespan.

By following these instructions and using low heat, you can effectively use your nonstick pan without damaging the coating and maintain its nonstick properties for a longer period of time.

Avoid metal utensils

When using a nonstick pan, it is important to avoid metal utensils. Metal utensils can scratch or chip the coating, which can cause the pan to need replacing. Instead, opt for wooden or silicone utensils, such as a wooden spoon or a silicone spatula.

The nonstick coating on a pan is designed to prevent food from sticking to the surface. This coating can be damaged by metal utensils, which can leave scratches and chips in the surface. These scratches and chips can then provide new places for food to stick, reducing the effectiveness of the pan and making it more difficult to clean.

In addition to the practical issues of scratched and chipped nonstick coatings, there are also potential health risks associated with using metal utensils on nonstick pans. The nonstick coating on a pan is typically made of a plastic material that can break down at high temperatures, releasing toxins into the air. If the coating is already damaged by metal utensils, it may be more likely to release these toxins during cooking.

To extend the lifespan of a nonstick pan and to protect your health, it is important to avoid using metal utensils when cooking with nonstick cookware. By choosing wooden or silicone utensils instead, you can help to keep your nonstick pan in good condition and avoid the potential release of toxins into your food.

It is also worth noting that, while metal utensils should be avoided when cooking with nonstick pans, other types of cookware may not have the same restrictions. Stainless steel pans, for example, are better suited for high-heat cooking and can be used with metal utensils without the same risk of damage. However, it is always important to use the appropriate utensils and cooking techniques for the specific type of cookware you are using to ensure optimal results and maintain the longevity of your kitchen equipment.

Don't use cooking spray

Nonstick pans are designed to reduce the need for additional fats and oils in cooking. However, sometimes a little extra something is needed to guarantee that food slides right off the pan. Despite the temptation, you should avoid using cooking spray at all costs.

Cooking sprays can cause a build-up of residue around the edge of nonstick cookware that simply doesn't burn off. This residue is difficult to remove and can degrade the cooking surface, causing food to stick. This residue is caused by lecithin, an additive used as an emulsifier in cooking sprays like PAM. Lecithin sticks to non-stick coatings and can start to congeal at very low temperatures, forming a sticky film. This buildup can also occur on stainless steel pans, but since it’s easier to see on a lighter surface, you’re more likely to scrub it off before it becomes a problem.

The use of nonstick spray can also interfere with the cooking process, leading to uneven cooking and browning. Nonstick pans are designed to distribute heat evenly, but the spray residue can impair this process. Additionally, nonstick spray is so damaging to nonstick surfaces that it can potentially void your pan's warranty.

Instead of using cooking spray, opt for cooking fats like butter or olive oil. These can be added to the pan as soon as it's exposed to heat, as cooking fat amplifies the coating's effect. Butter or margarine can also add flavor to your dishes. For cooking at higher temperatures, oils with high smoke points, such as avocado, canola, or grapeseed oil, are suitable.

Preheat with oil or butter

When using a nonstick pan, it is generally recommended to preheat it with oil or butter. This is because nonstick pans are designed to prevent food from sticking to their surface, and preheating them with a cooking fat can amplify this effect.

To preheat a nonstick pan with oil or butter, first, add a small amount of your preferred cooking oil or butter to the pan. You can use options like olive oil, vegetable oil, or any other cooking oil you have on hand. Then, place the pan on your stovetop and turn the heat to a low or medium setting. Avoid using high heat, as it can damage the nonstick coating and release toxins.

Let the pan heat up gradually. It usually takes around 5 to 8 minutes for the pan to heat up properly. You can use a surface thermometer to check the temperature of the pan if you want to be precise. An ideal temperature range for preheating your nonstick pan is between 425 to 450 degrees Fahrenheit.

Once the pan is properly heated, you can add your food. If you're cooking delicate ingredients like eggs or fish, a nonstick pan is an excellent choice as it prevents sticking. Just be sure to use utensils made of wood or silicone, as metal utensils can scratch the nonstick coating.

Measure temperature with a thermometer

To measure the temperature of a nonstick pan with a thermometer, place a surface thermometer in the centre of the pan and turn it on. Give the pan time to heat up—this should take around 5 to 8 minutes. Regulating the temperature of your pan will come with practice, as you get to know your stove and cookware and how they react with each other.

It is important to note that nonstick pans should not be heated above 400–500 degrees Fahrenheit. At these high temperatures, the molecules on the coating break down and release fluorocarbons into the air, which are linked to respiratory illness. Therefore, it is recommended to use nonstick pans for cooking that requires medium or low heat, such as eggs and vegetables, and to use stainless steel pans for cooking at high heat.

Additionally, when heating a nonstick pan, avoid using cooking spray, as it causes a build-up of residue that is difficult to remove and can damage the pan. Instead, use cooking fats like butter or olive oil. Add these to the pan as soon as it is exposed to heat, as this amplifies the coating's effect.

It is also worth noting that some nonstick pans can release toxins when heated without any cooking fat, so be sure to always add some form of fat before heating the pan.
