Benefits Of Cooking With Cast Iron

Why a Cast-Iron Skillet Belongs in Every Kitchen

There are a host of practical and culinary reasons why cast iron is experiencing a comeback.

It Improves with Use

One of its greatest advantages is that a cast-iron pan is possibly the only piece of kitchen gear you can buy that noticeably improves after years of heavy use. As you cook in it, a cast-iron pan gradually develops a natural, slick patina, called seasoning, which releases food easily. A well-seasoned cast-iron skillet can become just as nonstick as an aluminum or stainless-steel pan and will definitely outlast them.

It Maintains Heat

Cast iron doesn't heat very evenly because its thermal conductivity, or ability to transfer heat from one part of the metal to another, is very low. What cast iron does do well is hold on to heat: Once a cast-iron pan is hot, it will stay that way much more effectively than stainless steel. This makes cast iron the ideal material for high-heat applications like searing steak. The initial drop in temperature caused by adding the relatively low- temperature steak to the hot skillet will be much smaller in cast iron, allowing for higher heat and better browning. And better browning means a more delicious steak.

It's Virtually Indestructible

The durability of cast iron is legendary—many people are still cooking on cast-iron pans handed down through their family for generations. Cast iron is virtually indestructible and easily restored if mistreated.

It Can Develop a Nonstick Coating

Cast iron's ability to develop a nonstick coating also makes it incredibly versatile. This is a boon for minimalist cooks who are looking to downsize their pot and pan collections to a few key pieces that can work in almost any application, but cast iron is also beloved by gourmet cooks who appreciate the particular benefits it offers for essential techniques like browning and searing.
