Unbleached Parchment Paper

Parchment paper sits at the safer end of the baking accessory spectrum — but there are meaningful differences between products, and the type you choose matters.

All parchment paper gets its non-stick property from a silicone coating applied to the cellulose fibers. Food-grade silicone is chemically stable and considered inert at typical baking temperatures. Most parchment is rated for use up to 420–450°F (215–232°C), and staying within that range means the silicone coating remains stable and does not meaningfully transfer to food. If you regularly cook at higher temperatures — broiling, high-heat roasting, or pizza-oven style cooking above 500°F — parchment is not the right tool; the paper itself can scorch and the silicone may begin to break down.

The bleached vs. unbleached distinction matters more than most labels suggest. Bleached white parchment is processed with chlorine compounds, and while finished products are rinsed, trace organochlorine residues can remain in the paper. These compounds can migrate in small amounts during baking, particularly at higher temperatures or with fatty foods. Unbleached (brown) parchment skips the chlorine bleaching step entirely and is the cleaner choice, especially for frequent use.

A compostable label is worth verifying — some products claim compostability but use silicone coatings that only break down in industrial facilities, not home bins. Look for certification from recognized composting standards if backyard composting is important to you.

For those wanting to eliminate single-use waste entirely, reusable silicone baking mats are an excellent alternative. They handle higher temperatures than parchment, are dishwasher safe, and perform comparably for most baking tasks. The main trade-off is cost upfront and limited use for tasks like wrapping or parceling food.
