Ovenproof

Ovenproof is a term used to describe cookware, bakeware, and other containers that are designed to withstand the heat of an oven. Items labeled or marketed as ovenproof are suitable for baking, roasting, or finishing dishes in an oven, rather than being limited to stovetop use or serving only.

Common ovenproof materials include tempered glass and borosilicate glass, ceramic and stoneware, cast iron, enameled cast iron, and many types of metal pans that are rated for oven use. Plastics, wood, and some nonstick coatings are typically not ovenproof unless explicitly stated by the manufacturer. The suitability of an item depends on its construction, materials, and any coatings or seals.

Temperature ratings for ovenproof cookware vary by material and brand, typically from about 350 F (175 C) to 500 F (260 C) or higher. Cast iron and many metal pans often tolerate high heat, while glass and ceramic bakeware can be more prone to thermal shock and should be heated gradually and protected from sudden temperature changes. Always consult the product’s instructions for the maximum oven temperature and whether broiling is advised.

Care and safety considerations include avoiding abrupt temperature changes, using appropriate racks and handles, and following cleaning guidelines. Some ovenproof items are dishwasher safe, while others require hand washing. If in doubt about a piece’s oven suitability, rely on the manufacturer’s labeling and guidelines to prevent cracking, warping, or other damage.
