Nonstick pots and pans are widely used for everyday cooking. The nonstick coating makes it easy to flip pancakes, turn sausages, and fry eggs, and is especially helpful for cooking delicate foods that might otherwise stick.
However, there is some controversy around nonstick coatings like Teflon.
Some sources claim these coatings are harmful and linked to health conditions such as cancer, while others assert that cooking with nonstick cookware is completely safe.
This article explores nonstick cookware, its potential health effects, and whether it is safe to use.

How long does a Teflon pan can last?
The lifespan of a Teflon (non-stick) pan can vary based on several factors, including the quality of the pan, how it is used, and how well it is maintained. On average, a Teflon pan can last between 3 to 5 years. Here are some key factors that can influence its longevity:
- Quality of the Pan: Higher-quality Teflon pans, often with multiple layers of coating and better construction, tend to last longer than cheaper, lower-quality ones.
- Usage: Frequent and heavy use can wear down the non-stick coating more quickly. Using metal utensils can scratch and damage the surface, reducing its lifespan.
- Maintenance: Proper care can significantly extend the life of a Teflon pan. This includes avoiding high heat, not using metal utensils, and hand-washing the pan instead of using a dishwasher. Additionally, using wooden or silicone utensils can help prevent scratches.
- Heat Exposure: Overheating a Teflon pan can cause the non-stick coating to degrade faster. It’s best to use medium or low heat and avoid preheating an empty pan.
- Cleaning: Gentle cleaning with a soft sponge and avoiding abrasive cleaners can help maintain the non-stick surface. Allowing the pan to cool before washing it can also prevent warping and damage.
When the non-stick coating starts to peel, chip, or significantly wear off, it is time to replace the pan, as using a damaged Teflon pan can pose health risks and reduce cooking performance.
How do you care for Teflon cookware?
Caring for Teflon cookware properly can extend its lifespan and maintain its non-stick properties. Here are some tips for proper care:
Before First Use
- Wash and Season: Wash the pan with warm, soapy water and dry it thoroughly. Lightly coat the surface with a small amount of oil, then wipe off the excess with a paper towel.
During Use
- Use Appropriate Utensils: Use wooden, silicone, or plastic utensils to avoid scratching the non-stick surface. Avoid metal utensils, which can damage the coating.
- Avoid High Heat: Use low to medium heat settings. High heat can cause the non-stick coating to break down over time.
- Cooking Spray: Avoid using cooking sprays, as they can build up residue on the pan that is difficult to remove. Instead, use a small amount of oil or butter if needed.
After Use
- Allow to Cool: Let the pan cool down before washing it to prevent warping or damage from sudden temperature changes.
- Hand Wash: Wash the pan by hand with warm, soapy water and a soft sponge or cloth. Avoid using abrasive cleaners, steel wool, or scouring pads.
- Remove Stuck-on Food: For stubborn, stuck-on food, fill the pan with warm soapy water and let it soak for a few minutes before gently scrubbing with a soft sponge.
General Maintenance
- Avoid Stacking: If you need to stack your Teflon pans, place a paper towel or a soft cloth between them to prevent scratching.
- Store Properly: Store your Teflon cookware in a safe place where it won’t be jostled or scratched by other items.
- Regular Inspection: Periodically inspect your Teflon pans for signs of wear, such as scratches, peeling, or flaking of the non-stick coating. Replace the pan if it shows significant damage.
By following these tips, you can help ensure that your Teflon cookware remains in good condition and performs well for as long as possible.
Can I still use the pan when all the coating is gone?
It’s not safe to use a pan with a damaged non-stick coating, especially if you overheat it. Overheating can release toxic particles and gases, some of which are carcinogenic. These particles are invisible because they break down at the molecular level.
Pots vs. Pans
- Pots: If the pan is a pot, it’s less of an issue because pots are usually used for cooking liquids and don’t reach high temperatures. Non-stick coatings aren’t really necessary for pots.
- Skillets/Frying Pans: If it’s a skillet or frying pan used for high-temperature cooking (like searing), it’s best to replace it. High heat can cause the non-stick coating to break down and release harmful substances.
Choosing a New Pan
When buying a new pan, consider avoiding non-stick coatings. Instead, opt for heavy-based stainless steel or cast iron pans. These can be made non-stick through proper usage and can handle high temperatures better.
Making a Stainless Steel Pan Non-Stick
- Heat the Pan: Place the empty pan over high heat until it reaches the Leidenfrost point (water droplets bead up and roll around).
- Add Oil: Pour out the water, add a small amount of oil, and heat for about 30 seconds.
- Cook: Add your food (like a steak) and let it sear undisturbed for about 2 minutes before flipping. Avoid overcrowding the pan to maintain the heat.
Seasoning a Cast Iron Pan
- Heat the Pan: Bring the pan to a high temperature.
- Add Oil: Spread a little oil to coat the inside of the pan.
- Cool and Wipe: When the oil starts to smoke, remove the pan from the heat, let it cool, and wipe it with a paper towel.
Cooking Tips
- Fond Formation: When searing meat in these pans, you’ll see a fond form on the base. This isn’t burning; it’s the meat proteins creating flavour. The meat will lift away easily once it’s seared.
- Deglazing: After cooking, add some liquid to the hot pan to release the fond, using a spatula to help remove any stubborn bits.
Durability
Stainless steel and cast iron pans, if cared for properly, can last a lifetime and rarely need replacement.
Alternatives to Nonstick Cookware
Modern nonstick cookware is generally considered safe. According to the American Cancer Society, there are no proven risks to humans from using new PFOA-free nonstick cookware.
If you’re still concerned about potential health effects, here are some excellent Teflon-free alternatives:
- Stainless Steel:
- Uses: Great for sautéing and browning food.
- Benefits: Durable, scratch-resistant, and dishwasher safe, making it easy to clean.
- Cast-Iron Cookware:
- Uses: Naturally nonstick when properly seasoned.
- Benefits: Long-lasting and can withstand very high temperatures.
- Stoneware:
- Uses: Has been used for thousands of years for even heating.
- Benefits: Nonstick when seasoned, scratch-resistant, and can be heated to high temperatures.
- Ceramic Cookware:
- Uses: A newer option with excellent nonstick properties.
- Considerations: The coating can be easily scratched.
- Silicone Cookware:
- Uses: Ideal for bakeware and kitchen utensils.
- Considerations: Not suitable for direct heat but great for baking.
These alternatives provide various benefits and can be a great addition to your kitchen if you’re looking to avoid nonstick coatings.
The Bottom Line
Nonstick cookware is popular in many kitchens worldwide.
The nonstick coating, made from PTFE (also known as Teflon), makes cooking and cleaning easy. There were concerns about PFOA, a compound previously used in making Teflon, but Teflon has been PFOA-free since 2013.
Today’s nonstick and Teflon cookware is considered safe for everyday home cooking, as long as you don’t exceed temperatures of 260°C (500F).
Use your nonstick cookware on the stovetop at low-to-medium heat, but avoid using it at maximum heat or for high-temperature cooking methods like broiling.
In summary, Teflon cookware is a convenient and safer option for everyday cooking. However, ongoing research on other substances used in making Teflon suggests there may still be potential safety issues.
