Non-Toxic Non-Stick Cookware

non-toxic non-stick cookware

I’ve been getting a lot of questions about non-toxic, non-stick cookware in my Facebook Group, the Green Product Forum, so I wanted to share some tips and specific product recommendations here.

Many people think first of reducing or eliminating plastic from their kitchen, to reduce exposure to chemicals like BPA. But the conversation is moving now to a different challenge: how can you replace your Teflon™ cookware, without sacrificing performance – and why would you want to?

What is Teflon™?

Teflon™ is the trade-name for chemical manufacturer DuPont’s non-stick cookware. It’s like the “Kleenex” of non-stick cookware, but other brands exist. It is made from polytetrafluoroethylene, or PTFE. (Yes, PTFE, not PFOA. If you’re royally confused because all you’ve heard about Teflon™ is how toxic PFOA is, you aren’t alone… read on.)

Is Teflon™ Toxic?

Teflon™ got a bad reputation because PFOA (perfluorooctanic acid) was historically used in the manufacturing process. PFOA is now banned, not because of a health risk in cookware, but because it was found to be contaminating water supplies near manufacturing plants. It is a carcinogenic, hormone disrupting, persistent environmental toxin (meaning that once it enters the environment, it doesn’t leave). It is generally accepted that very little PFOA remains on a product by the time it gets to the consumer.

The Canadian Cancer Society appears to be more concerned about TFE, which is used to create the non-stick coating. It has been identified by the International Agency for Research on Cancer (IARC) as a “probably cause of cancer” and it may be released from PTFE-coated non-stick cookware at high heat.

And for those of you interested in the Rock Pans, they still contain PTFE. The ceramic options are PTFE-free, but from what I’ve seen don’t have great performance reviews online.

If you wish to continue using Teflon™ or other PTFE coated pans, do not dry-heat them (i.e. make sure there’s always water or oil in them when heating) and use them only at low heat. Studies have shown the chemicals can off-gas at normal frying temperatures. It is commonly recommended to discard scratched Teflon™ products, as this exposes the centre of the coating which is not intended to come in contact with food.


Non-Toxic Non-Stick Cookware

If you’re ready to move away from Teflon™ for your pots and pans , the good news is that you’ve got options. If non-stick is your primary goal, cast iron and ceramic are probably your best bets.

Cast iron pans are heavy, but they really will last a lifetime. Keep them well-oiled (“seasoned”) and make sure they’re dry before storing. Avoid cooking acidic foods, like tomatoes, as they will eat away at the pans. The washing process can seem daunting, but once you learn it, it takes very little time.

Here’s a quick video where I walk you through how to season cast iron:

If cast iron isn’t for you, then consider ceramic. These enamel-coated pans have a shorter use history, but from research I’ve done they are generally considered safe. Look for brands that are lead- and cadmium-free (like Lagostina or Green Pan), as there are some concerns that products made outside North America may not follow the same safety standards. Like Teflon™, the coating is prone to scratching and these pans have to be treated with care. They have a much shorter life than cast iron, so you probably only need one – perhaps a larger one if the large cast iron pans are too heavy for you.

Stainless steel cookware would not be considered non-stick without copious amounts of oil or grease. But it does clean up nicely with a scouring pad and some elbow grease. They are also long-lasting and affordable. The elements that make up stainless steel (and cast iron), iron, nickel, and chromium, are thought to be released at low enough levels to not pose a concern to our health (unless you’re allergic to nickel).


I hope this helps you navigate the options for detoxing your kitchen with respect to non-stick cookware. If you haven’t joined the Green Product Forum yet, it’s a great place to get advice on products for your whole home! Request to join here.
