If you like to cook, you know that your tools make all the difference. Using the right ingredients, the right knives, and the right pans can help elevate a recipe from good to great. The problem is finding the pan that works for you.
There are so many types of pan that it can get confusing, so why not look to the professionals? Serious chefs use both cast iron and carbon steel pans daily in professional restaurants worldwide. I wanted to learn more about the difference between these top-tier types of cookware, and here’s what I found:
Carbon steel and cast iron are both versatile materials that can go in the oven or on the stove. Carbon steel is slightly lighter and more durable than cast iron, but cast iron retains heat for longer, helping cook food more evenly. Carbon steel is great for searing and cooking quickly, while cast iron is better for grilling and cooking deeply.

How are Carbon Steel and Cast Iron Similar?
This video is a good explanation of how cast iron and carbon steel compare. I’ve summarized the information below.
Cast iron and carbon steel share a lot of similarities. If you’re trying to decide whether to buy a new pan in the first place, then understanding why these pans are so well-loved can help.
Both cast iron and carbon steel pans are:
- Made of iron. Both cast iron and carbon steel are primarily made of iron. This makes them great at retaining heat. It also means that both styles need to be seasoned and maintained for the best results.
- Versatile. Both styles of cookware can be moved from the stove to the oven and back again. They can also be placed on induction stoves, over campfires, or anywhere else.
- Heat-safe. Some other types of cookware like aluminum or non-stick pans can scorch in extreme heat. Carbon steel and cast iron can safely be used in any temperature that you’d use for cooking.
- Durable. The best part about steel and iron is how sturdy it is. Plenty of people have the same cast iron pans their grandparents had. As long as cast iron and carbon steel are treated well, they can last forever.
How are Carbon Steel and Cast Iron Different?
So, what make these two materials unique?
Material. The first difference between carbon steel and cast iron is the material itself. Steel and iron typically have some trace carbon as part of their mix.
Resilience. Carbon is a crystalline structure, so it’s not as flexible as pure steel. The more carbon is part of a pan, the less flexible it is. Since cast iron has more carbon than carbon steel, cast iron pans aren’t quite as resilient. If you drop a carbon steel pan on the ground, the worse it will suffer is a scuff and maybe a small dent. Cast iron, on the other hand, can fracture if it lands just right.
Shape. Carbon steel pans wind up with sloping, curved side at a 60 degree angle. On the other hand, cast iron pans have straight, upright sides. This can affect cooking in certain styles.
Heat retention. Cast iron heats slowly and cools slowly. Carbon steel is thinner, so it heats and cools more quickly.
Cooking with Cast Iron vs. Carbon Steel Pans
Cooking with cast iron and carbon steel is rewarding no matter what. However, they do have different strengths when it comes to different foods.
If you’re looking for a traditional frying experience, cast iron may be slightly better than carbon steel. Cast iron’s heat distribution is perfect for crisping chicken skin, searing steaks, and . However, carbon steel can also fry foods well.
Stir-fry and Sautéing
If you’re looking to fry things with a bit of style, carbon steel is easier to work with. Tossing things in a pan requires sloping sides with a bit of a curve, which carbon steel pans provide. The material also cools more quickly, so your stir fry won’t burn when you take it off the heat.
Best of all, carbon steel is smoother, so stuff is less likely to stick to the cooking surface.
Roasting and Broiling
If you want to roast or broil something, cast iron and carbon steel come out about even. They both move easily between oven and stove. It can be a little easier to move a carbon steel pan, though, because it’s lighter. If you need to finish something in the oven, carbon steel is a good choice.
Skillet breads like a classic cornbread were designed to be cooked in cast iron. The tall sides are ideal for keeping your cornbread or skillet cookie contained while it bakes. Carbon steel can work, too, but the sides will be less crispy because the thinner material doesn’t retain heat as well.
When it comes to creamy pastas, cast iron can be a little better than carbon steel, again because of its straighter, taller sides. However, if you’re looking to make a tomato-based dish, use something else entirely. The acid in tomatoes can quickly degrade both carbon steel and cast iron’s seasoning and lead to rust.

How to Season Cast Iron and Carbon Steel
Seasoning is the one difficult part about owning cast iron or carbon steel. However, it’s not hard to do it well. Here’s how to season cast iron and carbon steel like the pros.
There are three reasons to season a pan: it’s new, it’s lost its seasoning, or you’re maintaining its current seasoning. The first and second reasons require an in-depth seasoning process.
Seasoning or Reseasoning a Pan
First, clean any built-up material from your pan. New pans can arrive covered in a wax to prevent rust, while old pans likely have grime stuck to the walls and bottom. Scrub it out with very hot water and a scrubbing pad. Put the pan on the stove on low heat to dry off the water.
Once the pan is dry, slice an onion into the pan. Add a third of a cup of oil and two-thirds of a cup of salt. The salt will scrub any remaining grime out of the pan, while the oil and the onion will create an even, smooth layer of polymerization – the seasoning.
Cook the mixture for about fifteen minutes on medium heat. The onions should be just about burnt by the time you’re done, and the inside of the pan should be evenly brown. That’s the seasoning you want to maintain. Dump the contents of the pan and rinse it out with hot water, and you’re ready to cook.
Maintaining Seasoning in a Pan
It’s much easier to keep your seasoning in good shape than it is to reseason a pan.
To maintain your seasoning, rinse and scrub your pan after you cook with a soft sponge and warm water. Dry your pan on a still-warm burner. Once the pan is dry, add a small drizzle of oil to the pan and rub it into the whole cooking surface. Wipe out the extra oil as much as you can. Now you’re ready to cook again.
What Is Cast Iron?
Cast iron is one of the most traditional forms of cookware out there. These pans have been around for centuries, and they were hugely popular in the first half of the 20th century. Cast iron is made by pouring a mixture of iron with at least 2% carbon into a mold and allowing it to cool. The result is a thick, durable, piece of cookware that can retain heat better than anything else on the market.
Cast iron is also relatively cheap. The most popular cast iron manufacturer today is Lodge, who sells 12” cast iron skillets for just $20. That’s comparable to non-stick skillets, and it’s within reach of just about every budget.
Because of how cast iron cookware is made, it has a distinctive shape. Most cast iron cookware has a completely flat bottom with sides that shoot up at a nearly 90 degree angle. The entire cooking surface can be nearly a half inch thick, so it takes a long time to heat up. However, this thick cooking surface also means that it retains heat for a long time, so you don’t have to worry about moving the pan around while you’re cooking.
The molding process results in a thick, lightly pitted surface. Cast iron is great for holding onto its seasoning because of those pits, but those same pits can also cause food to stick if the seasoning is damaged.
What Is Carbon Steel
Carbon steel is a more modern cooking innovation. Carbon steel is typically 1% to 2% carbon, while cast iron is more than 2% carbon. (Yes, that means that cast iron has more carbon than carbon steel!) It’s often produced in sheets.
Carbon steel pans are made by putting a sheet of the steel in a large press, which stamps it into shape like a cookie cutter. As a result, carbon steel pans can be thinner, lighter, and smoother. Their super-smooth surface keeps food from sticking, but it’s easier to strip the seasoning from it. The stamping leads to a flat bottom but sloping, curved sides
The thinner, lighter material means that carbon steel heats up and cools down more quickly than cast iron. This can be a great choice for delicate ingredients that can burn quickly. However, if you’re trying to maintain a steady temperature while moving the pan, carbon steel is better than aluminum but not as great as cast iron.
Carbon steel pans are more expensive that cast iron in many cases. Made In, which makes some of the best carbon steel pans on the market, sells a 12” skillet for $90. Other brands retail for $50 to $60 on Amazon for the same size.
