When it comes to cooking up something delicious in a frying pan, the pan's material is almost as important as the ingredients in your recipe. Carbon steel and cast iron are great options if you want a frying pan that's durable enough to revive from an antique shop and keep in the family for generations to come. But what else do they have in common and what differences help you choose between the two?
They're manufactured from similar materials, which gives them similar function, abilities, limitations and care requirements. Here are some of the most notable similarities:
Both cast iron and carbon steel can easily and safely transition from stovetop to oven or from oven to stove top. This means both can be used either to fry up a breakfast on the burner or to bake a berry cobbler that crumbles to perfection.
Both contain ferromagnetic metals, which means they will function on an induction stove top. So, they will not suddenly become obsolete when you decide to update your kitchen appliances.
Neither cast iron or carbon steel is good for an acidic sauce. In fact, both have reactive cooking surfaces and acid will break down their seasoning and slick surfaces.
Both types of pans function best when well seasoned (a process of saturating the cooking surface with an oil or fat). Seasoning a cast iron or carbon steel pan will reduce the reactivity of its surface and will also create an almost non-stick texture. Check out our article on seasoning to make sure you're

the right way.
Neither pan should be washed in the dishwasher or exposed to harsh detergents - it'll totally break down the pan's age-earned seasoning. Hot water with a scouring pad works best. If absolutely necessary, mild washing soap is OK.
Even though carbon steel and cast iron both contain a combination of about 99% or 98% iron and 1% or 2% carbon, their differences, although subtle, are enough to create a difference on the stovetop.
- Carbon steel is slightly more durable than cast iron. Cast iron's heavy fabrication makes it fairly brittle in comparison, which means it can fracture or shatter if dropped.
Fabrication and Cooking Surface
- Cast iron cookware is formed in a cast, which creates pocked, uneven surfaces with bigger pores. Since carbon steel is much more malleable, sheets of the material are pressed or hand-formed into cookware with smoothly curving sides and a much more even cooking surface.
- Cast iron weighs significantly more than carbon steel. Cast iron has a much thicker, denser body. Carbon steel is similar to stainless steel in terms of its weight.
- If a hot cooking surface is what you want, then a cast iron pan is the right choice because cast iron retains heat extremely well. A cast iron pan is slow to warm up and slow to cool down, but at its peak, it will remain very hot. On the other hand, carbon steel retains heat quite well when compared to other cooking materials, but not as well as cast iron. However, carbon steel heats up and cools down more quickly than cast iron, making it a good option for more delicate ingredients.
- The differing heat retention qualities of the two types of pans predispose them to different types of cooking. While both do well baking inside the oven, they cook quite differently on the stove top. Cast iron's ability to retain heat lends it grill-like cooking tendencies. This makes it perfect for hamburger patties or anything which requires lots of intense heat for the perfectly juicy meal. Carbon steel is better for stir-frying vegetables or searing chicken, which could easily burn in a pan that doesn't cool quickly enough. Carbon steel's smoother surface also makes it a better choice for delicate meals containing fish or scallops which could easily catch and tear on the rough surface of a cast iron pan.

Whatever your preference, there's always room for experimentation. Adding new pans and surfaces to your cooking arsenal is never a bad thing. More pans = more food!
