Coating Non-Stick Pans: Oil's Role Explained

Non-stick pans are coated with a protective layer that prevents food from sticking to the pan. However, this non-stick quality can deteriorate over time due to improper cleaning, scratches, or stains. To maintain the non-stick properties of the pan, it is recommended to season the pan with oil. This process involves coating the pan with a thin layer of oil and heating it, allowing the oil to fill in scratches and reinforce the non-stick coating. While cooking sprays should be avoided due to their negative long-term effects on the pan, oils such as vegetable, olive, and coconut oil are recommended for seasoning non-stick pans.

Oil prevents non-stick pans from overheating and releasing toxins

Non-stick pans are coated with PFAS, or per- and poly-fluoroalkyl substances, also known as "forever chemicals". These include the likes of PTFE, commonly known as Teflon, which gives non-stick pans their slippery capabilities.

According to Teflon, this chemical coating begins to erode when it reaches temperatures of 348°C (660°F) or higher. When non-stick pans are left to heat up without any oil or grease, they are prone to reaching this temperature even quicker, which can gradually ruin them.

The use of oil or grease in non-stick pans is therefore important to prevent overheating and the subsequent release of toxins. Heating a non-stick pan without any oil or food is not advisable.

Some non-stick pans can emit potentially unhealthy fumes when heated without a lubricant. The pans are more likely to release toxins when the non-stick surface is chipped or flaked. To stay safe, it is recommended to replace the pan every couple of years before this becomes an issue.

When cooking on the stovetop, keep the heat at medium or lower to protect the pan's non-stick surface.

Non-stick pans can be re-coated with oil to restore their non-stick properties

Non-stick pans are a godsend when it comes to cooking delicate foods that are prone to sticking to the pan. They also make cleaning up a breeze. However, non-stick pans are not invincible and their non-stick properties can deteriorate over time.

Why Non-Stick Pans Need Oil

Non-stick pans have a coating of PFAS (per- and poly-fluoroalkyl substances), also known as "forever chemicals", which includes PTFE, commonly known by the brand name Teflon. This coating begins to break down at temperatures of 348°C (660°F) or higher. Therefore, heating a non-stick pan without any oil or grease can cause it to reach this temperature and gradually ruin the pan.

How to Re-coat Non-Stick Pans with Oil

If your non-stick pan is losing its non-stick properties, you can restore it by re-coating it with oil. This process is known as "seasoning" the pan. Here's how to do it:

• Clean the pan thoroughly to remove any stains or food particles. You can do this by filling the pan with water and adding 1/2 cup of white vinegar. Bring the mixture to a boil, then wash the pan with gentle dish soap, avoiding abrasive tools that can scratch the pan.
• Dry the pan completely. It's important to have a dry surface for the oil to stick to.
• Heat the pan over medium heat for a few minutes.
• Add a thin layer of oil to the pan. You can use vegetable oil, canola oil, coconut oil, or peanut oil. Avoid using olive oil, as it has a low smoke point and can start to smoke at higher temperatures.
• Heat the oil until it smokes, then remove the pan from the heat and let it cool completely.
• Wipe out any excess oil with a paper towel.
• Repeat this process every few months to maintain the non-stick properties of your pan.

Tips for Maintaining Non-Stick Pans

• Avoid using cooking sprays, as they can leave a residue that builds up over time and affects the non-stick properties.
• Use wooden or silicone utensils instead of metal utensils to prevent scratching the pan.
• Avoid cooking over high heat. Stick to low or medium temperatures to protect the non-stick coating.
• Wash your non-stick pans by hand with soft sponges, brushes, or microfiber towels. Avoid using abrasive cleaning tools like steel wool.

Oil prevents food from sticking to the pan

Using oil or grease in non-stick pans is therefore recommended. However, cooking sprays should be avoided as they contain lecithin, which tends to cling to non-stick coatings. Instead, oils such as vegetable, olive, grapeseed, coconut, and peanut oil are recommended. A thin layer of oil should be added to the pan before heating it up.

Oils with a high smoke point, like peanut oil, are best for seasoning non-stick pans

Oils with a high smoke point are best for seasoning non-stick pans. The smoke point of an oil is the temperature at which it starts to smoke. Using an oil with a high smoke point gives you more room for error.

Peanut oil is a great choice for seasoning non-stick pans as it has a smoke point of 450°F. It is also a good neutral oil, so it won't impart any unwanted flavours to your food. Peanut oil is perfect for stir-frying veggies or frying foods like French fries, crispy chicken, and tempura.

Other good options for seasoning non-stick pans include canola oil, grapeseed oil, and avocado oil. Canola oil has a smoke point of 400°F and is very versatile. Grapeseed oil has a smoke point of 390°F and is great for sautéing. Avocado oil has a very high smoke point and is a healthy option for cooking at high temperatures.

When seasoning a non-stick pan, it is important to use a thin layer of oil and heat it gently. This will help to create a non-stick surface and protect your pan.

Cooking spray ruins non-stick pans

Non-stick pans have a coating of PFAS, or per- and poly-fluoroalkyl substances, on their surface. These chemicals are also known as "forever chemicals" due to their persistence in the environment. The PFAS coating includes substances like PTFE, commonly known as Teflon, which gives non-stick pans their slippery properties.

While non-stick pans offer convenience and ease of cleaning, they need to be treated with care to avoid damage. One common mistake that can ruin non-stick pans is the use of cooking spray. While it may be tempting to use cooking spray as a convenient and low-calorie alternative to traditional oils or butter, it can actually be detrimental to your non-stick cookware.

Cooking sprays often contain propellants, silicones, and emulsifiers, including lecithin. Lecithin, in particular, tends to cling to the non-stick coating of the pan, creating a stubborn buildup over time. This buildup forms an invisible barrier, causing food to stick to the pan instead of the non-stick surface. The more you use a cooking spray, the more this buildup will occur, and it can be extremely difficult, if not impossible, to remove.

Instead of reaching for the cooking spray, opt for a minimal amount of oil, such as canola, olive, vegetable, or corn oil. Butter is also an excellent option, providing a natural lubricant for your non-stick pan. If you're watching your calorie intake, consider investing in an oil mister, which allows you to coat the pan with a controlled amount of oil.

In summary, while non-stick pans offer convenience and ease of cooking, it's important to remember that they require special care. Avoiding the use of cooking sprays and opting for healthier alternatives like oils or butter can help maintain the non-stick properties of your cookware and ensure its longevity.
