For years, I thought I had it figured out.
We stopped using aluminum foil, ditched the non-stick pans, and switched to glass and cast iron cookware.
We even avoided plastic containers and only drank from stainless steel or glass bottles.
But I still used parchment paper almost every week.
It felt like a harmless, even smart choice — We used it to line baking trays, wrap roasted veggies, even reheat things in the toaster oven. No scrubbing. No mess. It felt “clean.”
Until one day, I stumbled down the rabbit hole…
WAKE-UP CALL!🔥
Most parchment paper is coated with either silicone or a chemical called quilon, which can leach toxins when heated.
Regular parchment paper is usually coated with either -
- Silicone (heat-resistant, generally considered safer),
- or Quilon, a cheaper compound containing chromium, a heavy metal.
When heated (especially above 425°F), these coatings can break down and release toxic compounds — especially if you’re using it directly on hot surfaces or open flame.
Chromium exposure from quilon-coated paper may pose carcinogenic risks, especially with frequent use.
And even silicone-coated parchment, while better, isn’t inert. Over time, silicone can degrade and release compounds — especially if it's poor quality or exposed to high heat repeatedly.
Just because it’s in the “natural aisle” doesn’t mean it’s harmless.
Parchment paper can be okay — but know what it’s coated with, and don’t crank the oven to max with it.
Because small, daily exposures add up — and you’re not crazy for caring.
