Pan-demonium in the kitchen
We Tested Nonstick Cookware: Coatings Don't Need to Look Worn to Shed Particles
Your ‘perfect’ nonstick pan may be flaking out before it even looks damaged
TLDR: Tests found some brand-new nonstick cookware released visible particles before any obvious wear, and higher price didn’t guarantee cleaner performance. Commenters instantly split into skeptics and anti-nonstick converts, with many declaring stainless steel and cast iron the real kitchen heroes.
The kitchen internet is having a full-on nonstick meltdown after tests suggested some brand-new coated pans can release visible particles into oil even when they look perfectly fine. The big gasp? Expensive didn’t automatically mean better. In fact, two of the pricier coated products reportedly got worse after wear, which sent commenters straight into “so we’re paying more to shed more?” territory.
The comment section quickly turned into a cookware civil war. One side praised the testing and wanted more of it, especially after the RTINGS founder jumped in to stress that they bought multiple units, washed them repeatedly, and used control samples to rule out obvious contamination. But there was also a note of caution: the study counted visible particles, it didn’t prove health harm, and it didn’t chemically confirm every particle. That caveat became fuel for the debate.
Meanwhile, the anti-nonstick crowd smelled blood. Commenters proudly announced they’d dumped coated pans and joined Team Stainless, Team Cast Iron, and Team Carbon Steel, insisting the “nonstick is easy” myth is mostly about cooking technique, not magic coating. One user basically gave the community’s tough-love pep talk: if they can learn stainless steel, you can too. Another called constantly replacing coated pans “wasteful” and bragged about uncoated steel pans lasting 12 years and still being a joy to use.
So yes, the science got attention — but the real show was the crowd reaction: part consumer panic, part cookware flexing, and part “welcome to your stainless-steel villain origin story.”
Key Points
- •The article tested whether PTFE-coated cookware can release particles into cooking oil before visible damage appears.
- •Six products were tested across skillets and air fryer baskets, including uncoated controls, with each product tested in triplicate when new and after standardized wear.
- •Some brand-new PTFE-coated cookware released substantially more filter-visible particles than oil and uncoated cookware controls.
- •The new All-Clad D3 PTFE skillets released more detectable particles than the controls and the other new cookware tested, even though only a plastic spoon was used.
- •After standardized wear, every PTFE-coated product tested released more particles than in new condition, and the largest increases were seen in two of the highest-priced PTFE-coated products.
