Parchment is mostly coated with silicone, which some sources claim can be toxic when heated
. However, other research shows that silicone-coated parchment paper has non-detect results for organic fluorine, and the silicone coating is considered food-safe and non-toxic
.
How to Use Parchment Paper Safely (If You Choose To)
Don't panic! You don't necessarily need to throw out all your parchment paper. Here's how to use it more safely:
✅ Choose Unbleached Parchment Paper
Always opt for unbleached or food-grade labeled parchment paper
. Unbleached versions don't undergo chlorine processing and are safer for high-heat cooking.
✅ Look for PFAS-Free Brands
Some brands have been lab-tested and found to be free of PFAS "forever chemicals"
. Look for brands that:
- Use plant-based silicone oil coatings
- Don't use chlorine in production
- Are transparent about their manufacturing process
✅ Respect Temperature Limits
- Stay within the manufacturer's temperature rating (usually 425-450°F)
- Don't use parchment paper under the broiler
- For cooking above 400 degrees, consider using foil instead
✅ Consider Safer Alternatives
- Silicone baking mats: Reusable, non-stick, and don't contain PFAS
- Well-seasoned cast iron: Natural non-stick surface
- Glass or ceramic baking dishes: Often don't require lining
- Lightly greased pans: Use avocado oil or another heart-healthy fat
The "Avocado Lover's" Kitchen Swap!
Since I have a strong personal preference for avocados and incorporate them into almost every single meal (even though my children absolutely do not share my liking for them, which just means I get to enjoy the whole batch!), I've been transitioning to safer kitchen practices.
Instead of parchment paper, I now use:
- Silicone baking mats for my Cheesy Mashed Potato Puffs and other baked treats
- A light brushing of avocado oil on my baking pans—the heart-healthy monounsaturated fats are fantastic for relaxing my blood vessels and supporting my circulation, and they work beautifully as a natural non-stick agent!
- My well-seasoned cast iron skillet for roasting vegetables
My Personal Bottom Line
After all my research, here's what I've decided:
I still use parchment paper occasionally, but I:
- Only buy unbleached, PFAS-free brands
- Stay well within temperature limits
- Use it sparingly, not for every single baking project
- Opt for reusable silicone mats whenever possible
The key is being informed and intentional. You don't need to throw everything out in a panic, but you should think twice and make conscious choices about what you're bringing into your kitchen.
