Cast iron cookware has been around for hundreds of years and is one of the most durable and long-lasting cooking materials known when looked after; they can last for 100 years or more. They can last for 100 years or more but can a cast-iron skillet be used in the oven?
Cast iron skillets and pots can withstand very high temperatures and transfer from the stovetop into the oven without risk of damage due to the material’s natural characteristics. Part of the seasoning and curing process requires your cast iron skillet to be in the oven for about an hour!
Now, let’s examine what makes an oven-safe skillet, why, how, and when cast iron skillets can go in the oven, and how best to season, cure and maintain them.
Oven Safe Cast Iron Skillets Add a New Cooking Dimension
Cast iron skillets especially enameled cast iron, are ideal for oven use and add another string to your cooking bow. A significant advantage of cast iron is that it doesn’t lose temperature when cold food is added.
They hold temperature exceptionally well and heat evenly throughout the skillet, so roasts, stir-fries, chicken, eggs, and even cornbread come out superbly using cast iron. To keep food warm or keep it cooking you can place your skillet in the oven with total confidence.
The other aspect of using your cast iron skillet in the oven is that it can safely go under the grill or broiler to finish off foods that need some browning, like cheesy-topped potato bakes and such.
Just check with the manufacturer beforehand to ensure your skillet is broiler/grill compatible. Especially the handles they should be made of cast iron or riveted metal handles, avoid wooden handles and silicone handles.
Seasoning and Curing Cast Iron Skillets in the Oven
One of the great attractions of cast iron is that you can season it to give that black non-stick finish. This process is called polymerization and involves heating layers of fat or oil to turn them into plastic.
While many people believe that seasoning is an oil layer, it’s a plastic-type compound that binds to the metal to give it that natural non-stick finish and allows you to cook and clean the skillet easily.

- Clean cloth
To season your skillet, you will wash it properly first with dish soap and warm water then dry it thoroughly. You can use a tiny bit of soap on the first wash after you unpack it, and after that, you only need warm water.
Once the skillet is thoroughly dry (wipe it again after drying to be sure), add a thin layer of lard, cooking oil, olive oil, or canola oil to the skillet as these oils are non-flavored and have a high smoke point. Make the whole skillet is oiled inside and out, then take a paper towel and lightly wipe any excess oil off.
Heat your oven to 375° F, and once at the temperature, place your skillet pan upside down on the middle rack. Have a drip tray underneath to catch any oil that drips off during the process. Then leave it to bake for an hour, turn the oven off, and let the skillet cool down completely.
If you don’t have an hour to cure it, you can heat the oven to 450°F and leave it to bake for 30 minutes.
You may need to repeat three or four times as polymerization requires multiple layers to be baked on to form the non-stick surface.
A cast-iron skillet oven-safe temperature? Your cast-iron skillet will melt at around 2200°F and only start experiencing metal fatigue at around 700°F, so you are in no danger of damaging the skillet during seasoning and curing.
Once the initial seasoning is done, regular cooking and cleaning will result in more layers of fat being built up over time, so you probably won’t need to cure it again.
However, if the skillet is left for a long time, you may find that it isn’t quite as non-stick as it was so you can repeat the seasoning and curing process.
Once the layers have built up, you can even cook the acidic type foods in your skillet without too much concern.

Caring for Your Cast-Iron Skillet
While cast iron is immensely strong and durable, not caring for it properly will result in the seasoning coming off, and not washing and drying properly can lead to rust and corrosion. To keep your cast-iron skillet in top shape, here are a few simple tips.
Never put a hot skillet into cold water
This can cause the metal to crack due to the sudden temperature drop known as thermal shock. Let your skillet cool down before washing it.
Wash your skillet immediately after use
Using just water and cloth or a non-steel scourer, wipe the skillet clean and rinse. Then, once completely dry, you add another light layer of oil to maintain the seasoning.
Don’t submerge your skillet completely in water
Never leave your skillet in the water. This can lead to rust and corrosion-it only needs to be wiped to clean it.
Store your skillet in a dry cupboard
Once the skillet is dry and oiled, store or hang it in a dry cupboard or where there is good airflow. Remember that moisture is the enemy of cast iron, so oiling after use, proper drying, and storage in a dry area will extend the life of your cast-iron skillet. Learn how to store cast iron correctly for rust-free cookware.
Don’t use metal cleaning tools
Once the skillet has cooled enough to handle it safely, use a plastic brush or scrubber to wash it. Most foods stuck to the bottom will come off without too much effort due to the non-stick surface. If you need to scrape a little off, use a plastic or wooden implement to do that. At the same time, you could use a steel one, but it’s better to use a material that could never scratch the metal surface.
Try not to simmer acidic foods like tomato sauces in your skillet
Even when seasoned, simmering, or exposing the cast iron to highly acidic foods can remove the layer of seasoning and impart a metallic taste to your food.
Don’t drop the skillet
Even though cast iron is tough, it’s also very heavy, and if dropped on concrete or similar hard surfaces, it can crack; not only that, but it can certainly cause injury if it lands on your foot, so handle it with care.
Before cooking, preheat the skillet with some oil
Start with the skillet on low heat and add some oil; then, once warm, take the heat to the temperature required.
Properly used and cared for, your cast iron skillet will give you a lifetime of great cooking and flavor, and as they can go in the oven, you don’t need to have different cookware to make all your favorite dishes and have them come out as masterpieces every time!

What should you not cook in cast iron?
To preserve seasoned cast you should avoid cooking aromatic foods (why does my cast iron smell) like garlic and peppers. Delicate food such as fish not only leaves a smell but will stick if the iron’s surface is compromised, as will eggs. Acidic foods like lemon and tomatoes will wear the seasoned surface down quicker than if you do not use these ingredients.
Never fear seasoned cast iron can always be restored – so cook whatever you want if you are prepared to care for your cast iron.
