Stainless steel is a great option for non-toxic, long-lasting, durable cookware ideal for boiling, sautéing, and baking. It is especially good for small-batch baking as it retains heat well and cooks foods evenly.

Disadvantages of stainless steel cookware

One possible downside of stainless steel is that it may leach heavy metals into food. This is more likely if you cook acidic foods in a stainless-steel pot for a long time. Stainless steel can contain iron, chromium, and nickel, the latter having no nutritional benefit in the body. Nickel has also been linked to adverse health effects, including sensitization to allergic (contact) dermatitis in some people.

Anyone who is nickel sensitive should consider an alternative to stainless steel. This is because, while stainless steel cookware is available that is either very low in nickel or nickel-free, such cookware is extremely prone to corrosion. Nickel is included in the stainless-steel alloy largely to help with rust resistance. It also helps increase the hardness of the stainless steel and gives it a polished look and feel.

To make things even more confusing, stainless steel is also classified as being in the 200, 300, or 400 series. The 200 series has manganese in place of nickel, which makes cookware less expensive but more prone to corrosion. The 300 series (sometimes labeled as 304 or 316) is a higher quality range that is much more resistant to corrosion. Surgical grade steel is 316, for example, as the alloy contains some titanium and/or molybdenum to increase resistance to salt water (saline) erosion.

The cheapest stainless-steel cookware is usually in the 400 series. This alloy is more corrosive as it is almost entirely nickel-free. It is often found in mixing bowls, kitchen utensils, and cheap stockpots.

The benefits of stainless steel cookware

Stainless steel is a great option for non-toxic, long-lasting, durable cookware ideal for boiling, sautéing, and baking. It is especially good for small-batch baking as it retains heat well and cooks foods evenly.

Stainless steel is also easy to clean and care for, making it especially helpful for novice cooks, such as students living away from home for the first time. Just clean with hot soapy water after use, or scrub down with steel wool to remove any layers of oil that have accumulated.

Stainless steel is also a versatile material for cookware. You can easily find stainless steel pots and frying pans, as well as griddles, lasagna pans, roasting trays, muffin tins, and baking sheets.

One of the best options for stainless steel cookware is a 3-ply design layering stainless steel, aluminum, and stainless steel. This layering helps to seal in the aluminum – so you don’t need to worry about leaching – while harnessing aluminum’s better heat conductivity to produce a more homogenous cooking surface. This type of design is also easier to clean, dishwasher safe, and is sturdier and more polished than some cheaper cookware made purely with low-quality stainless steel.

How to season stainless steel cookware

One potential downside of stainless steel is that you typically need to use more oil to avoid food sticking to the pan. Learning to cook on a lower heat can help prevent food from sticking, but more advanced cooks might want to season their stainless steel to create a natural non-stick coating for frying pans or saucepans.

To season a stainless-steel pan:

1. Heat the pan on a moderate heat and then add a generous amount of oil.
2. Let the oil reach its smoking point, then turn off the burner and let the pan cool.
3. Once the pan is cool, pour off the oil and wipe the pan clean

The surface of the pan should now be reflective and is seasoned to be non-stick. It will stay non-stick as long as the pan isn’t cleaned with soap. This is because when the pan heats, the metal expands. The oil then sticks to the surface as the pan cools and the metal contracts. A seasoned stainless-steel pan is great for cooking tofu scrambles, eggs, crepes, and similar dishes.
