Compared to non-stick cookware (like Teflon), it avoids the potential health concerns associated with synthetic coatings at high temperatures.
Potential Health Benefits of Cooking with Carbon Steel
One of the main draws of carbon steel is its potential to positively impact your health. These benefits mainly stem from the minimal chemical interactions and the possibility of iron enrichment.
Iron Enrichment in Food
Cooking with carbon steel can potentially increase the iron content of your food. This is particularly beneficial for individuals with iron deficiencies or those at risk of developing them, such as women of childbearing age and vegetarians. The amount of iron leached into food depends on several factors, including the acidity of the food and the cooking time.
However, it’s important to note that the amount of iron absorbed from cookware is generally small and should not be considered a primary source of iron. Consuming iron-rich foods remains the most effective way to maintain healthy iron levels.
Avoiding Harmful Chemicals
Unlike non-stick cookware coated with materials like Teflon (PTFE) or PFOA, carbon steel does not leach harmful chemicals into food at high temperatures when properly seasoned. This makes it a safer option for those concerned about the potential health risks associated with synthetic coatings. The seasoned layer acts as a barrier between the food and the raw metal.
Durability and Longevity
Carbon steel cookware, when properly cared for, can last for generations. This durability reduces the need for frequent replacements, minimizing waste and contributing to a more sustainable lifestyle. The investment in a good quality carbon steel pan can pay off over time, both financially and environmentally.

Proper maintenance and seasoning are paramount to maximizing the health benefits and minimizing the risks associated with cooking with carbon steel. These practices will ensure your cookware remains in optimal condition for years to come.
The Seasoning Process Explained
Seasoning carbon steel involves repeatedly heating a thin layer of oil on the surface of the pan. This process polymerizes the oil, creating a hard, non-stick coating. Common oils used for seasoning include flaxseed oil, canola oil, and grapeseed oil. Each oil has a different smoke point and contributes to the seasoning in a unique way.
The general process involves applying a very thin layer of oil to the pan, wiping off any excess, and then heating it in the oven at a high temperature (typically between 350°F and 500°F) for an hour. This process is repeated several times to build up a strong, even layer of seasoning.
Cleaning and Care Tips
To maintain the seasoning on your carbon steel pan, avoid using harsh detergents or abrasive scrubbers. Clean the pan with hot water and a soft sponge. For stubborn food particles, you can use a small amount of dish soap. Always dry the pan thoroughly after washing and apply a thin layer of oil to prevent rusting.
Avoid soaking the pan in water for extended periods. This can damage the seasoning and cause rust to form. If rust does appear, you can remove it with steel wool and re-season the pan.
Recognizing and Addressing Seasoning Issues
Over time, the seasoning on your carbon steel pan may become uneven or start to flake. This can be caused by using too much oil when seasoning, cooking acidic foods, or using abrasive cleaning methods. To address these issues, you may need to strip the pan down to the bare metal and re-season it from scratch.
Regular use and proper maintenance will help maintain the seasoning and prevent these issues from occurring. Pay attention to how your pan is performing and adjust your cleaning and seasoning practices accordingly.
