Non-stick pans are designed to prevent food from sticking, but sometimes food does stick. This can be due to a variety of reasons, such as high heat, low heat, incorrect cleaning, or overcrowding the pan. To prevent food from sticking to your non-stick pan, it is important to use the right heat, avoid scratches, and clean the pan thoroughly. Choosing the right type of pan and oil can also help prevent sticking.

High heat
The coating is made from a gas that is frozen and then compressed into a waxy substance. When exposed to high heat, it will start to degrade like a candle and turn back into a gas. This is why the coating will start to flake and break down.
Additionally, when heated above 400-500 degrees Fahrenheit, the molecules on the coating break down and release fluorocarbons into the air. These polymers are common in household products, but inhaling them is linked to respiratory illness.
To prevent this from happening, it is recommended to only use non-stick pans for cooking at low or medium heat. For cooking at high heat, it is recommended to use a stainless steel or cast-iron pan.

Low heat
Non-stick pans are not designed for high heat. Using a non-stick pan on high heat can damage the coating, causing it to stick. High heat can also cause the release of harmful toxins, depending on the type of coating on your pan.
To prevent your non-stick pan from sticking, always use low or medium heat when cooking. This will prevent burning and keep the coating from breaking down.
Even if you use low heat, the coating of a non-stick pan can still be easy to scratch with metal utensils. Superficial scratches won't affect the pan's performance, but deeper scratches that expose the metal underneath can cause your food to stick and the coating to flake off into your food.
If you're constantly scraping food out of your pan, even when using plenty of oil, this is a sign that the non-stick coating is starting to wear down. Another sign is if the surface of your pan is discoloured and won't come clean with washing.
To restore the non-stick coating, mix 1 cup of water, 2 tablespoons of baking soda, and 1/2 cup of white vinegar in the pan, then boil for 10 minutes. Wash the pan as usual, then rub vegetable oil on the surface to re-season it.

Incorrect cleaning
- Using abrasive tools such as steel wool, scouring pads, or stiff scrubbing brushes to clean the pan. These can damage the non-stick surface, creating scratches and exposing the metal underneath. Instead, use a soft cloth, sponge, or non-abrasive scrubber.
- Putting non-stick pans in the dishwasher. While some non-stick pans are labelled dishwasher-safe, handwashing is the best option. The high temperatures and detergents used in dishwashers can break down the non-stick surface.
- Using metal utensils with non-stick pans. Metal utensils can scrape and damage the non-stick coating. Opt for wooden or silicone utensils instead.
- Overheating non-stick pans. High heat can damage the non-stick coating over time. Avoid temperatures above 500 degrees Fahrenheit, as this can cause the coating to break down and release potentially dangerous fumes.
- Heating an empty non-stick pan. Always add oil, water, or food to the pan before turning on the burner. This will help prolong the life of the non-stick coating.
- Using non-stick cooking spray. Cooking sprays can burn at a lower temperature than the non-stick coating, damaging the pan. They also create a residue that builds up over time and ruins the non-stick surface.
- Rinsing a hot non-stick pan with cold water. This can cause the pan to warp, ruining its shape. Always allow the pan to cool completely before cleaning.

Oil not coating the surface
If the oil in your non-stick pan is not coating the surface, it could be due to a few reasons. Firstly, it is important to note that non-stick pans are designed to prevent substances from adhering to them. Therefore, it is normal for oil to bead or pool in certain areas of the pan rather than coating the entire surface. This does not necessarily indicate an issue with the pan or imply that your food will stick to the surface. As long as all of the food comes into contact with some oil, it should not stick to the pan.
However, if you are experiencing sticking, there are a few potential causes and solutions to consider. Firstly, ensure that you are using enough oil. While it is not necessary for the oil to coat the entire pan, it is important to use a sufficient amount to prevent sticking. Additionally, the type of oil you use can make a difference. Some oils, such as certain spray-on oils, can bond permanently to the surface of the pan, effectively ruining its non-stick properties. Therefore, it is recommended to use oils such as canola, vegetable, or coconut oil.
Another factor to consider is the heat you are cooking at. Heat is the number one culprit that can destroy the coating of your non-stick pan. When heated above 500 degrees Fahrenheit, the coating can turn toxic and begin to deteriorate. Therefore, it is recommended to cook at medium or low heat and to always add oil before heating the pan. Heating an empty non-stick pan can cause the coating to degrade faster.
Finally, over time, the non-stick coating on your pan will start to wear down, and food residue can build up, causing sticking. To prevent this, it is important to properly care for your non-stick pan. Avoid using metal utensils that can scratch the surface, and hand wash the pan instead of putting it in the dishwasher. Additionally, be sure to season your pan regularly with oil to reinforce its non-stick properties.

Pan overcrowding
Overcrowding your pan can lead to less-than-ideal results when cooking. Adding food to a pan lowers its temperature, and the more food you add, the lower the temperature falls. This means that a crowded pan will cool down faster, and as it does so, your food will start to stick to the pan, won't brown properly, and will release its moisture.
To avoid pan overcrowding, you can use a larger pan, making sure it's nice and hot, or cook your food in batches, a little at a time. For smaller foods, only add enough to cover the bottom of the pan in a single layer. For larger foods, such as chicken pieces or steak, leave an inch or two between them, and make sure they don't touch.
If you're cooking for a lot of people, using multiple pans or a large electric skillet can be helpful. You can also try cooking in batches and keeping the food warm in the oven until it's all ready to be served.
Remember, overcrowding your pan can lead to soggy, unevenly cooked food, so it's best to avoid it whenever possible.

Frequently asked questions
There are several reasons why food sticks to non-stick pans. Here are some of the most common issues:
- High heat: When you overheat a non-stick pan, food can burn and stick to the pan's surface. Over time, high heat can also degrade the coating.
- Low heat: When you add food to oil in a pan over low heat, the food may not release water vapour, which creates a barrier between the food and the pan's surface, causing the food to stick.
- Incorrect cleaning and care: Not properly cleaning and maintaining your non-stick pan can scratch and degrade its non-stick coating, leading to food sticking to the exposed metal surface.
- Poor oil distribution: If the oil doesn't coat the entire surface of the pan, food is more likely to stick. This can happen if the pan is warped or the stove isn't level.
To prevent food from sticking, try the following:
- Choose PTFE non-stick: PTFE non-stick coatings last longer than ceramic coatings because they are more resistant to damage.
- Use a pan with a multi-layer coating: Pans with multiple layers of non-stick coating take longer to break down and are less likely to expose the metal underneath.
- Avoid metal utensils: Metal utensils can scratch the non-stick surface. Opt for wooden, plastic, or silicone utensils instead.
- Choose a pan with a heavy bottom: Thicker metal absorbs and disperses heat more evenly, preventing hotspots and sticking.
To clean and maintain your square non-stick pan:
- Hand wash with warm soapy water: Even if your pan is dishwasher-safe, hand washing is recommended to prolong its lifespan.
- Avoid metal utensils: Metal utensils can scratch the non-stick coating. Use wooden, plastic, or silicone utensils instead.
- Season your pan: Seasoning your non-stick pan can help seal the pores and fortify the non-stick coating. Heat a clean pan on high, add canola or vegetable oil, spread it with a paper towel, then heat on medium for 1-2 minutes. Let it cool, then wipe off the excess oil.
If your non-stick pan is heavily scratched, warped, or chipped, it's time to replace it. Additionally, if you find yourself constantly scraping food from the pan or noticing discolouration that won't wash off, it's likely time for a new one.
