Understanding Cookware Materials: Stainless Steel, Cast Iron, or Aluminum

Having the right cooking tools is just as crucial as having quality ingredients to execute unforgettable dishes. Restaurant owners know that type of pot and pan have their own culinary purpose. However, it’s good to also examine how cookware materials influence the ingredients that go on the final plate.

Read on for a comprehensive breakdown of the most used materials in cookware and the best one for your needs.

Which is Better, Stainless Steel, Cast Iron, or Aluminum?

With a variety of materials at a chef’s disposal, it’s common to wonder which is the most beneficial. There isn’t a clear winner between stainless steel, cast iron, or aluminum. They each bring their own pros and cons and best application.

Stainless Steel Cookware

Stainless steel is steel with the addition of chromium and nickel. The result is an anti-corrosive, iron-dense material. In premium pots and pans, there is usually an 18/10 stamp, indicating the ratio of chromium (18) to nickel (10).

Stainless steel cookware does not react to acidic or alkaline foods, meaning chefs can cook any type of dish without worrying about the metal corroding and imparting off flavors into food. It will not rust or oxidize, making stainless steel induction burner safe. Plus, it is dishwasher, oven, and broiler safe.

One of the major downsides to stainless is its average heat distribution. Pure stainless steel is nearly impossible to use for cookware applications. To circumvent the heat issues, manufacturers bond layers of highly conductible metals—like copper and aluminum—to stainless steel to improve heat distribution. Pots and pans with layered additional metals are known as “clad.”

Cast Iron Cookware

Cast iron is one of the oldest cooking materials, originating in China 2,700 years ago. In the U.S. cast iron pots and pans started gaining popularity as early as 1896 with Lodge Manufacturing. To create cooking pieces out of cast iron, steel and iron are mixed, melted together, and then poured into molds to shape the vessel as it hardens. 

One of the benefits of cooking with cast iron is its heat retention capabilities. Once it reaches a high temperature, its self-regulating nature allows the cookware to hold the temp for long periods of time. This makes it an ideal material for griddles, dutch ovens, fry pans, and skillets that handle high-heat cooking. 

Despite its incredible heat retention properties, it can take time for cast iron to come up to temp and cool down, making it not the best choice for on-the-fly cooking. Cast iron is porous, which means it is reactive to acid and susceptible to rust. One way to help combat this reaction is to diligently season any cast iron cookware with oil, not submerge it in water, and always wipe it dry before storing.

Aluminum Cookware

Aluminum is a lightweight and affordable material. It tends to be soft, so it is often fortified by adding magnesium, copper, or other strengthening elements. Aluminum is often a practical choice for roasting pans, rondeau, and large stock pots.

While it doesn’t excel at heat retention, aluminum cookware does an incredible job in terms of heat distribution. It warms quickly and cools fast, making it great for high-temp, fast cooking.

One challenge with aluminum is it’s extremely reactive to acid, which can significantly damage the cookware. For this reason, aluminum is often coated in a protective layer of polytetrafluoroethylene (PTFE), more commonly known as Teflon, which adds a non-stick finish. While research around the heath impacts of PTFE that wear off are ongoing, it’s important to know that overheating non-stick pans—especially above 500°F—can break down the coating and release fumes that may pose health risks. Proper care, such as using low to medium heat and avoiding metal utensils, helps maintain the coating and ensures safer cooking.
