Is HexClad Non-Toxic? What Flakes Into Dinner When the Pan Overheats (2026)

If one of these pans is in your kitchen, you know the pitch. The little laser-etched honeycomb, the steel peeking through, the demo where the guy drags a metal spatula across it and nothing happens. It looks like somebody finally solved the problem: all the ease of nonstick, none of the flaking.

Now pick it up and ask one plain question. If this is nonstick, what is making it nonstick?

The company already paid to stop answering that question a certain way.

Is HexClad actually non-toxic?

Quick answer: The company agreed in court to stop calling it that.

In November 2023, a class action was filed in Los Angeles County Superior Court, Cliburn et al. v. One Source to Market, LLC, case number 23STCV28390. The complaint alleged that HexClad marketed its cookware as "non-toxic" and free of PFOA and PFAS while the nonstick surface contained PTFE, which is itself part of the PFAS family.

HexClad agreed to a $2.5 million settlement covering people who bought the cookware between February 1, 2022 and March 31, 2024. As part of the deal, the company agreed to stop advertising products as "non-toxic," "PFOA free" or "PFAS free" if those products contain PTFE or any chemical in the PFAS family.

HexClad denied any wrongdoing and said it settled to avoid the cost of a long fight. That is their right, and it is worth saying plainly. But read the terms again. A company that genuinely believed the word was accurate does not agree to stop using it.

That is the whole story in one line: the words came off the marketing because a court case put them there.

What is the nonstick surface actually made of?

Quick answer: PTFE, the same family of compound that has been in nonstick pans for decades.

The steel honeycomb is real. It is genuinely clever engineering, and it does protect the surface from a metal spatula. But the steel is not what stops the egg from sticking. Sitting down in the valleys between those raised steel peaks is a nonstick coating, and in the original hybrid line that coating is PTFE.

PTFE is a fluoropolymer. It belongs to the group of compounds regulators call PFAS, the ones that have picked up the nickname "forever chemicals" because the carbon-fluorine bond does not readily break down in the environment or in us.

So "PFAS free" was never a small marketing stretch. The nonstick part of the pan was the PFAS.

Does the coating actually come off into food?

Quick answer: Barely at gentle heat. A lot when the pan gets hot and empty.

This is where I want to be fair, because the honest answer is not "your pan is poisoning you." It is more specific and more useful than that.

Researchers at the Fraunhofer Institute measured exactly this. In a 2015 study published in Chemosphere, Schlummer and colleagues heated PTFE food-contact surfaces and trapped what came off. Their finding was clear:

• At normal cooking temperatures, below about 230°C (446°F), total emissions came to about 4.75 nanograms per hour. Essentially nothing.
• Overheated pans "released far higher amounts with up to 12,190 nanograms per hour at 370°C (698°F)."

That is roughly a 2,500-fold jump, and the authors said it directly: "Temperature seems to be the main factor controlling the emission."

Now put that next to how people actually cook. An empty pan left on high heat while you get the kids to the table climbs past 400°F in a couple of minutes and keeps going. Preheating a skillet for a sear, walking away to answer the door, forgetting the burner under an empty pan. That is not abuse. That is Tuesday.

There is also a documented condition here with a name. Polymer fume fever shows up in the medical literature, and one of the most common causes listed is accidentally overheating nonstick cookware at home. Symptoms look like a short bout of flu: chills, fever, cough, tightness in the chest. It passes. It is also the body telling you something came off that pan and into the air you were breathing.

If you have birds, this stops being a nuance. Fumes from overheated PTFE are well known to be lethal to pet birds, which is why bird owners have been avoiding nonstick for years.

What about the new ceramic line?

Quick answer: Different coating, and worth noting, but it does not rewrite what you already own.

HexClad has since introduced a line using a proprietary ceramic coating it markets as PTFE-free and PFAS-free. That is a real change and I am not going to pretend otherwise.

Two honest caveats. First, ceramic nonstick coatings are generally less durable than PTFE and tend to lose their slip after a year or two of real family cooking, so you are trading one problem for a shorter lifespan. Second, and more to the point for most people reading this: the pan already in your cabinet is the pan you bought. A new product line does not change the coating on the one you have been searing chicken in since 2022.

So what do I actually cook in?

Quick answer: Materials that have no coating to fail in the first place.

Looking for a better coating is solving the wrong problem. The move is to stop needing one.

None of those need to be bought all at once. Replace one pan at a time as the old ones wear out.

How do I stop overheating the pans I already have?

Quick answer: Four habits, and you can start all of them tonight.

If you are not replacing anything this month, that is completely fine. Here is what actually lowers the risk with the pans in your cabinet right now.

1. Never preheat an empty nonstick pan. An empty pan has nothing absorbing the heat, so it races past 400°F fast. Put the fat and the food in first, then turn on the burner.
2. Keep nonstick on medium or lower. The Chemosphere numbers stayed near zero below 446°F. Medium heat on a home burner keeps you well under that.
3. Move searing to a different pan. Steak, smash burgers, anything you want a hard crust on, goes in cast iron or carbon steel. That is the exact job nonstick is worst at anyway.
4. Turn on the range hood, every time. Whatever comes off a hot pan, you would rather it went outside than into the room where everyone is eating.

Does this mean I wasted my money?

Quick answer: No. You bought a pan from a company that told you it was non-toxic, and you believed them.

I want to say this clearly, because the other feeling is awful. There is a specific kind of sick feeling that comes with finding out something you chose carefully, for your family, was not what you were told.

Please do not carry that. You are not careless. You read the front of the box, and the front of the box was the part a court eventually made them change. That is not a you problem. That is the whole reason I do this.

The only thing that actually works is the boring version: learn one thing, swap one thing, move on. Not a purge. Not a weekend of throwing things away and feeling terrible. One pan.

The woman who does that for a year is not the same woman who started. She is not anxious in her own kitchen anymore, because she is not guessing. She knows what her pans are made of, she knows why, and when a new product shows up with a clever demo and a confident claim on the front, she just asks the same plain question. What is making it do that?

That question is the whole skill. Everything else is just follow-through.

Frequently asked questions

Is HexClad safe to use if I never overheat it?

At normal cooking temperatures the measured release is extremely small. The 2015 Chemosphere study found about 4.75 nanograms per hour below 230°C. The risk lives at high heat, so if you keep it on medium and never preheat it empty, you have addressed the main pathway.

Is PTFE the same thing as Teflon?

Teflon is a brand name for PTFE. Different label, same compound family. That is why "PFOA free" was never the reassurance it sounded like: PFOA was a processing chemical that was phased out, but the PTFE itself is still a fluoropolymer in the PFAS family.

Do I qualify for the HexClad settlement money?

The claim period has closed. It covered purchases between February 1, 2022 and March 31, 2024, and payouts worked out to roughly six dollars per claimant. The useful part of that case was never the money, it was the fact that the company agreed to change the words.

Is cast iron really better, or is that just nostalgia?

It is not nostalgia. Cast iron has no applied coating, so there is no coating to degrade, flake, or release anything when it gets hot. It handles temperatures that would destroy a nonstick pan. It also lasts long enough that yours will outlive you.

What about the food I already cooked in it?

Do not spend one more minute on that. The amounts at normal cooking heat are tiny, and there is nothing to be done about the past anyway. Start where you are.
