Baking casseroles, lasagna, and oven dishes at moderate temperatures

Materials

Tempered or borosilicate glass

Common claims

Oven-to-table serving
Non-reactive surface

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.
