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


A casserole is a large and deep bowl and it is mostly used in the oven to cook a variety of foods. The casserole is made of different types of materials, so most people get confused in buying the casserole 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. 

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 the direct heat they will get disrupted completely 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?

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

If you are using a casserole that is made of metal then it 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 then it cannot be placed on direct heat such as a stovetop or any other induction stove. The Pyrex is considered an oven-proof but not a flameproof material, as it is highly sensitive to thermal shock and it will break the casserole when you used it under direct heat. 

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

Material Type and Temperature Affect

Are Casserole Dishes Flameproof

Ceramic Casserole Dishes

The hardness of ceramics makes them suitable for high temperatures. The ceramic casserole dishes have flameproof properties and can withstand temperatures up to 1650°C.

These dishes are designed to accommodate baking because of their large and deep dimensions. As these dishes are enameled and have flameproof properties but the flame can alter the color and affect the coating. 

The ceramic casserole dishes can easily withstand microwave and oven temperatures. These dishes are easy to clean, whether by hand or in the dishwasher, due to their smooth surfaces. Among their many uses, these dishes are also great for use directly in the oven from the freezer or even to serve food directly from the table.

Should You Use Casserole Dishes on the Stovetop?

The casseroles are always considered oven-safe but when it comes to the stovetop you need to make sure what type of material is used. If you are using metal casserole then it can be used on the stovetop, but the casserole dishes made of ceramic or glass have some limitations to be used on the stovetop.

When it comes to the casserole most casserole products are used only for baking purposes, and not for stovetop uses. Casseroles like cast-iron casserole can be used on the stovetop as they can withstand high temperatures from different sources. It can also be used in the oven.

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 amazing thermal shock resistance and the zero-crack glaze will protect the cookware.  

Even casseroles that are made of stainless steel can be used on both stovetop and induction as they can withstand higher temperatures.  

In recent times, most casseroles come flameproof and ovenproof, but before using make sure or else it will damage the product.

Can You Heat a Glass Casserole Dish on the Stove?

The casserole that is made of glass can be placed under direct heat. Also, if the casserole is made of Pyrex or borosilicate glass then it can be placed on direct heat as it will withstand higher temperatures and it has flameproof properties.

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

But there is one glass casserole that can withstand the higher temperature which is 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 it will withstand the high temperature 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.   

Are Pyrex Casserole Dishes Flameproof?

The pyrex casserole dishes can be placed on the stovetop but it is entirely based on the type of Pyrex used in the casserole. When compared to the other glass casserole, Pyrex has different chemical properties and will withstand direct heat. 

If you are using Pyrex cookware on the stovetop, then it has flameproof properties and is safe to use under direct heat. But sometimes even the Pyrex glass will get shattered if the direct heat is too fast and too uneven.

Only the Pyrex cookware can be placed on the stovetop, as other Pyrex products can’t tolerate such heat. All the types of Pyrex products are made of the same material which is soda-lime but in Pyrex cookware, the soda-lime used is heat strengthened.

So it will withstand the higher temperature and you can place it under direct heat as it has higher flameproof properties. 

So, before placing the Pyrex casserole or any other glass casserole on the stovetop make sure that it has flameproof properties. Or else the crystal structure of the product gets changed and it will result in the shattering or breaking of the product.

Final thoughts:

Most casserole dishes are made of ceramic, porcelain, and glass, but rather considering the casserole as cookware it is a bakeware product. In recent times, most people started to use casseroles for cooking also, as certain casseroles will withstand the higher temperature. But remember not all, so before using it check its properties.
