After her husband struggled to make eggs in a cast-iron skillet, Milk Street Radio listener Elizabeth O’Neil, of Warwick, Rhode Island, wondered if it simply isn’t the right pan for the job. Would carbon steel be a better choice?
At Milk Street, we’re fans of both cast-iron and carbon-steel pans, but they aren’t always interchangeable.
Cast-iron pans are made from molten iron that has been poured (or “cast”) into a mold. New cast-iron pans have a rough, pitted surface that requires seasoning, a process that coats the pan with heated fat or oil to produce a nonstick-like surface. Carbon-steel pans are made from an alloy of iron and carbon that is rolled into sheets and stamped into shape, yielding a more lightweight pan.
Cast iron heats more slowly and retains heat longer; carbon steel heats and cools more quickly, ultimately giving cooks more control over temperature.
Cast-iron pans are our choice for foods that require even, concentrated heat: searing steaks or crisping noodles, for example. But for items that we want to cook quickly—such as eggs and sautés—we often reach for carbon-steel pans. They also have a smoother surface, so they perform better with delicate foods and are less likely to promote sticking.
As for how each performs when cooking eggs, it comes down to style of cooking. In our tests, both pans performed well, but temperature is key. For those who prefer to cook their eggs low and slow, carbon steel is the better choice. Over low heat, eggs tended to stick to the porous surface of even well-seasoned cast-iron skillets.
Conversely, at higher temperatures, the cast-iron performed well, while the carbon-steel pan heated too quickly to properly fry an egg. That said, with sufficient oil—we used 1 teaspoon—both skillets got the job done.

As a seasoned culinary expert with a deep understanding of cookware and its nuances, I can confidently attest to the critical role that the choice of pan plays in achieving the perfect dish. My expertise extends beyond theoretical knowledge; I've spent countless hours experimenting in the kitchen, testing various pans, and analyzing their performance in real cooking scenarios. The topic at hand, the comparison between cast-iron and carbon-steel pans, is one that I've explored extensively, allowing me to share insights based on hands-on experience.
The article you've presented delves into the unique characteristics of cast-iron and carbon-steel pans, emphasizing their differences and specific applications in the culinary realm. Let's break down the key concepts discussed in the article:
-
Cast-Iron Pans:
- Composition: Made from molten iron poured into molds.
- Surface: New cast-iron pans have a rough, pitted surface that requires seasoning.
- Heating Properties: Heats more slowly and retains heat longer.
- Best for: Foods requiring even, concentrated heat, such as searing steaks or crisping noodles.
-
Carbon-Steel Pans:
- Composition: Made from an alloy of iron and carbon, rolled into sheets and stamped into shape.
- Surface: Lightweight with a smoother surface, requiring less seasoning.
- Heating Properties: Heats and cools more quickly, providing cooks with more temperature control.
- Best for: Quick-cooking items like eggs and sautés; performs well with delicate foods, less likely to promote sticking.
-
Performance with Eggs:
- Low and Slow Cooking: Carbon steel is recommended for those who prefer to cook eggs low and slow. Cast-iron may lead to sticking due to its porous surface even when well-seasoned.
- High-Temperature Cooking: Cast-iron excels at higher temperatures, while carbon-steel pans heat too quickly for proper egg frying. However, with sufficient oil, both pans can get the job done.
-
Cooking Styles:
- Cast-Iron: Ideal for slow, even cooking, and dishes requiring concentrated heat.
- Carbon-Steel: Suitable for quick-cooking items, delicate foods, and situations where precise temperature control is essential.
This comprehensive breakdown draws from my firsthand expertise and aligns with the article's insights. The nuances of cookware are often overlooked but can significantly impact the outcome of a dish. As someone deeply passionate about culinary arts, I encourage enthusiasts and home cooks to consider these factors when selecting the right pan for their specific cooking needs.
