Non-Stick Cookie Sheet

⚠️ USE WITH CAUTION

Baking cookies and roasting vegetables at high oven temperatures

Materials

Aluminum base
PTFE non-stick coating

Common claims

Easy release
Dishwasher safe
No-scratch baking

Concerns / watch-outs

Oven temperatures for baking (350–450°F) are exactly where PTFE begins to degrade
Dark non-stick sheets absorb more heat, accelerating coating breakdown

Notes

One of the worst-case scenarios for PTFE — used at exactly the temperature range where coatings degrade most. Strongly consider switching to stainless or parchment-lined aluminum.

Cleaner alternatives

Glass Casserole Dish

🌿 CLEAN & SAFE

Baking casseroles, lasagna, and oven dishes at moderate temperatures

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.
