Non-stick pans are a popular choice for home cooks, but they require special care to maintain their non-stick properties. While it may seem unnecessary to add oil to a non-stick pan, a small amount of oil or grease is recommended to prevent food from sticking and to extend the life of the pan. However, it's important to choose the right type of oil and avoid high temperatures to prevent damage to the pan's coating. Cooking sprays, for example, can leave a residue that builds up over time and invalidates the warranty. Instead, oils such as olive, vegetable, or grapeseed oil, or fats like butter, are recommended for non-stick pans.

Cooking spray damages non-stick pans
While non-stick pans are a boon for home cooks, they need to be treated with care. Non-stick pans are coated with PFAS, or per- and poly-fluoroalkyl substances, which give them their non-stick properties. However, this coating can be damaged by certain cooking practices, such as heating the pan without anything in it, cooking over high heat, or using the wrong kinds of oil.
Cooking sprays, in particular, have been identified as a common culprit for ruining non-stick pans. While cooking sprays are convenient and may seem harmless, they can contain various chemicals, including propellants, silicones, and emulsifiers, such as lecithin. These chemicals can interact with the non-stick coating and compromise its integrity. Lecithin, in particular, has a tendency to cling to the non-stick coating, building up over time and forming an invisible barrier that reduces the pan's non-stick properties. This can result in a sticky residue that is difficult to remove, even with thorough cleaning.
Additionally, cooking sprays may break down at high temperatures, further contributing to the buildup of residue. This residue can diminish the pan's effectiveness and shorten its lifespan. For this reason, most non-stick pan brands recommend avoiding cooking sprays altogether.
Instead of using cooking sprays, it is recommended to use a small amount of grease or oil when cooking with non-stick pans. Options such as butter, vegetable oil, olive oil, or grapeseed oil are suitable choices. A thin layer of oil can be added to the pan before heating it gently, allowing the oil to seal in and protect the non-stick coating.
It is also important to note that the choice of cooking oil and temperature control are crucial factors in maintaining the durability of non-stick pans. Some oils, like olive oil, have a low burn temperature, and using them over high heat can cause the oil to polymerize and fuse to the pan, damaging its functionality. Therefore, it is recommended to use non-stick pans over medium heat and to avoid overheating the pan.

Oils to use: olive, grapeseed, vegetable, butter
Using oil in a nonstick pan is a tricky business. While nonstick pans are designed to prevent food from sticking to the pan, oils can gunk up the nonstick coating and make it less nonstick over time. Therefore, it is recommended to use a minimal amount of oil in a nonstick pan.
Olive Oil
It is advised against using olive oil in a nonstick pan as it can ruin the surface. However, it is worth noting that half of Europe uses olive oil in nonstick pans pretty much exclusively.
Grapeseed Oil
Grapeseed oil is a good option for seasoning cast iron pans. It is a versatile cooking oil with a low smoke point, so it is not ideal for cooking with high heat. Grapeseed oil can produce an incredibly smooth and quite nonstick surface.
Vegetable Oil
Vegetable oil is one of the popular choices for seasoning cast iron pans. It is recommended to add vegetable oil to the pan and heat it, either slowly or quickly, at low or high temperatures.
Butter
Butter is not commonly mentioned as an option for nonstick pans. However, it is generally advised against heating a nonstick pan without anything in it, as it can ruin the surface and release toxic chemicals. Therefore, it is best to use butter in low to medium quantities in a nonstick pan.

Preheat the pan before adding oil
When it comes to cooking, preheating your pan is an essential step to master. While opinions vary on whether to add oil to a non-stick pan, there are several reasons why you should preheat your pan before adding oil.
Firstly, preheating your pan helps to ensure your food doesn't stick. This is because when metal heats up, its pores expand, and if the pan is heated first, the oil can settle into these pores. If oil is added to a cold pan, it will pool on top of the pores, and when food is added, it will push into the dry, unlubricated grain, causing it to stick. However, if you're using a non-stick pan, this isn't as much of an issue, and adding a small amount of oil to a hot non-stick pan can help prevent sticking.
Secondly, preheating your pan gives you more control over the cooking process. By heating the pan first, you know exactly how hot the pan is and can avoid overheating or burning it. This is especially important with non-stick pans, as heating them above a certain temperature can damage the non-stick coating and release toxic chemicals.
Additionally, preheating your pan can help prevent your oil from breaking down and forming sticky polymers that are difficult to remove. This is because heating the oil for a shorter time reduces the likelihood of it breaking down.
To preheat your pan effectively, use a surface thermometer to monitor the temperature. Start with a lower temperature than you think you need and adjust accordingly. Once the pan reaches the desired temperature, add your oil, and then immediately add your food.
In summary, preheating your pan before adding oil is a crucial step in the cooking process. It helps prevent food from sticking, gives you control over the temperature, and prevents the oil from breaking down. By following this step, you'll be well on your way to becoming a master chef!

Don't use high heat
Non-stick pans are not designed for high heat. Using high heat can damage the coating over time, causing it to crack. It can also lead to the release of harmful toxins, depending on the type of coating on your pan. For example, if you are using a high enough heat to polymerize the oil in a non-stick pan, your heat is too high and will ruin the pan.
To avoid damaging your non-stick pan, use low to medium heat when cooking. Heating a non-stick pan when it's dry and empty is also not recommended. Instead, add a few drops of oil or your choice of grease when you're ready to cook. This will help to amplify the coating's effect and prevent the release of toxins.
It's important to note that different oils have different smoke points, which is the temperature at which the oil starts to break down and produce smoke. Choosing an oil with a smoke point that is suitable for the temperature you are cooking at is essential. For example, olive oil has a smoke point of around 400 degrees Fahrenheit, which is higher than the temperature you should be using on a non-stick pan.
Additionally, avoid using cooking sprays on non-stick pans as they can damage the coating and invalidate the warranty. These sprays often contain propellants, silicones, and emulsifiers, including lecithin, which can build up on the pan over time and form an invisible barrier over the non-stick coating.
By following these guidelines and avoiding high heat, you can help extend the lifespan of your non-stick pan and ensure optimal cooking performance.

Pans should be hand-washed
While non-stick pans are a boon for cooking, they require special care to prevent their surface from scratching, peeling, or warping. Pans with non-stick coatings are sensitive and need to be treated with care. One mistake that will damage them over time is heating them dry. However, this does not mean that you can use just any grease.
Non-stick pans should be hand-washed with mild dish soap and a soft cloth or sponge. This is because the hot temperatures and detergents used in dishwashers can break down the non-stick surface. While cleaning, one should never use abrasive tools such as steel wool, scouring pads, or stiff scrubbing brushes, which can damage the surface. For stubborn residue, the pan might need to be soaked for a few hours in warm, soapy water before gently scrubbing it clean. If there is burnt oil or food residue stuck on the surface, adding a mild abrasive can help get the pan clean. A small amount of baking soda can be mixed with water to form a paste and applied to the pan. This can then be lightly scrubbed with a non-abrasive sponge to remove the residue, after which the pan should be rinsed, dried, and re-seasoned with a swipe of cooking oil.
Before using any brand-new non-stick pan, it is important to wash it to remove any residue from the packaging. This can be done using hot, soapy water, after which the pan should be thoroughly dried and seasoned before cooking. Seasoning non-stick cookware evens out any imperfections or pores in the coating and helps the pan last longer. This can be done by lightly rubbing cooking oil over the surface, then heating the pan on the stove over medium heat for two to three minutes. Once it cools down, any excess oil can be wiped out with a paper towel before storing.
It is also important to note that cooking sprays can damage non-stick pans. Most cooking sprays contain propellants, silicones, and emulsifiers, including lecithin, which clings onto the non-stick coating and cannot be removed by hand washing. Over time, the lecithin will build up on the pan and form an invisible barrier over the non-stick coating. Therefore, it is recommended to use some form of grease to prevent the non-stick pan from deteriorating over time. Butter is an excellent option, as are vegetable, olive, and grapeseed oils.
