Are Casserole Dishes Flameproof? [What You Need To Know]

A casserole is a large and deep bowl, and it is primarily used in the oven to cook a variety of foods. The casserole is made of different materials, so most people get confused about buying it as they don’t know whether the casseroles are flameproof. 

Are Casserole Dishes Flameproof?

Casserole dishes made from ceramic, porcelain, and cast iron have flameproof properties and can withstand very high temperatures ranging from 980 °C to 1,650 °C (1,800 °F to 3,000 °F). If your casserole is enamel-coated ceramics, then it will save your casserole from damage at high temperatures as it has flameproof properties. 

When using casserole dishes on the stovetop, indirect heat circulates all around it instead of just heating the base of the dish. You can use flameproof casserole dishes on the stovetop and in the oven, which reduces the amount of washing.

The Casserole dishes are made of metal like cast iron or seasoned casseroles, so the casseroles are considered flameproof and can be used on the stovetop and oven.

There are very few ceramic or glass casseroles. When you place them on direct heat, they will get disrupted, and the entire content will spill out. This is because of the expansion in the crystal structure.

How do I know if my casserole dish is flameproof?

Most casseroles are flameproof, but certain materials can’t be placed at a high temperature. So, before using any type of casserole, check its properties and what temperature it can withstand. But never put a metal casserole in the microwave oven. 

Using a casserole made of metal will withstand the higher temperature, so you will know that it is a flameproof dish. If you are using enamel-coated ceramic, then you can use it on the stovetop or oven as it has flameproof properties but make sure your oven is preheated, or else it will result in thermal shock.

If your casserole is Pyrex, a borosilicate glass, it cannot be placed on direct heat such as a stovetop or any other induction stove. The Pyrex is oven-proof but not a flameproof material, as it is susceptible to thermal shock and will break the casserole when you use it under direct heat. 

So, before you use the casserole on direct heat, make sure any symbols determine the casseroles have flameproof properties.

But certain casseroles are made of high-quality ceramics, which can be used on the stovetop as they can withstand direct heat from a stove or a grill. Even it has fantastic thermal shock resistance, and the zero-crack glaze will protect the cookware.  

Casseroles made of stainless steel can be used on both stovetop and induction as they can withstand higher temperatures.

If you use the glass casserole on the stove, heat will be received only from below, and it will also be more robust. It will result in the crack or exploding of the glass because of uneven heating. In most cases, the glass casserole can’t be used under direct heating as it will shatter. 

But one glass casserole can withstand the higher temperature: Pyrex. The Pyrex casserole comes in three forms such as cookware, bakeware, and glassware. You can place the cookware Pyrex on the stovetop as it is safe to use but not the glassware or bakeware casserole. 

Pyrex cookware is made of heat-strengthened soda lime so that it will withstand high temperatures, and also you can place it on the stovetop. The Pyrex bakeware will get shattered because of the high thermal shock caused by uneven heating.
