Unbleached Parchment Paper vs. Glass Casserole Dish

Materials

• Unbleached cellulose paper
• Silicone release coating

Common claims

• Non-stick baking liner
• Compostable option

Concerns / watch-outs

• Bleached versions may contain chlorine residue; opt for unbleached
• Single-use waste; silicone mats are a reusable alternative

Notes

Unbleached parchment is one of the lowest-concern oven liner options. Look for compostable versions to reduce waste.

Cleaner alternatives

• silicone baking mat

Materials

• Tempered or borosilicate glass

Common claims

• Oven-to-table serving
• Non-reactive surface
• Easy cleanup

Concerns / watch-outs

• Tempered glass can shatter with thermal shock — avoid moving from freezer directly to hot oven
• Borosilicate glass is more thermal-shock resistant than standard tempered glass

Notes

One of the most inert baking surfaces available. Choose borosilicate glass for better thermal shock resistance. Avoid the broiler, which can create extreme temperature differentials.

Cleaner alternatives

• glass bakeware
• enameled cast iron
