Stainless Steel Cookware: Quick Overview

Stainless steel cookware is a kitchen staple due to its attractive appearance, unmatched durability, and ability to do it all. That includes searing, browning, braising, broiling, boiling, sauteing, and much more.

The main features of stainless steel cookware are:

  • Shiny, scratch-resistant surface, though brushed (matte) options are also available.
  • Durable construction.
  • Excellent versatility. Great for stovetop, oven, and even grilling as long as the heat is kept below 500°F. Stainless steel is even compatible with induction ranges.

Construction

There are several stainless steel cookware variations, including fully-clad and impact-bonded. Fully-clad bonds pieces of metal together in what is called ply. Ply refers to the number of bonded layers in the cookware’s construction.

Stainless steel cookware labeled “fully-clad” means the conductive core layer is bonded seamlessly throughout, while those labeled “impact-bonded” are often cheaper and only include a conductive metal at their base (not up the sides).

The latter option won’t distribute heat as well as the former due to the limited scope of the conductive material.

Fully-clad stainless steel cookware commonly comes in three, five, or seven-ply options.

Despite what is sometimes advertised, the number of plys isn’t necessarily as important as the overall quality of the cookware’s production process.

How the metal is bonded, and its thickness tends to be more influential than the number of plys.

Appearance

Stainless steel cookware usually features a shiny polished exterior and a smooth silvery interior. It’s classy cookware that you can use to cook and serve the food.

You may see some pots and pans advertised as having a brushed finish. This finish is lightly sanded and polished with a non-abrasive pad to give it a dull, matte look.

Polished is the more traditional look, but brushed is gaining popularity because it’s sleek, modern, and hides scratches.

Downsides

Stainless steel cookware leans toward the more expensive end of the price spectrum, especially if you’re considering buying a higher quality or professional-grade product.

Still, many home cooks consider the higher price point worth it because this type of cookware can last a lifetime.

Stainless steel surfaces require special care during cleaning – they are generally more high-maintenance than other cookware. Never use steel wool or other abrasive materials when washing stainless cookware.

Stainless steel rarely includes a non-stick coating, which can cause frustration if cooking particularly sticky or flaky foods such as eggs or fish.

To avoid food sticking, consider seasoning the cookware. Make sure you read up and watch videos before attempting to season any pan, as taking the proper steps to avoid damaging the product.

Hard-Anodized Aluminum Cookware: Quick Overview

For consumers searching for durability and convenience, hard-anodized aluminum is worth considering. It’s often easier to use and less expensive than stainless steel, and it is relatively versatile.

Construction

Hard-anodized aluminum is manufactured by putting the aluminum base through an electromagnetic process that hardens and strengthens the metal, giving it superb durability.

Although bare hard-anodized aluminum was popular decades ago, today, almost every option now is non-stick, meaning the cooking surface is coated with a non-stick material (either PTFE or a ceramic-like natural sand-derived silicon).

Due to aluminum’s inherent conductive properties, this cookware distributes heat more evenly than its stainless steel counterparts. The non-stick coating means that it is easy to clean.

Appearance

Most hard-anodized aluminum cookware features a dark gray exterior and a black or charcoal cooking surface — a side effect of the anodizing process.

Unlike standard aluminum cookware that’s often painted bright and fun colors, hard-anodized cookware doesn’t come in many variations.

It certainly doesn’t look bad, and its classic appearance fits in well with any kitchen decor. But, if you’re into the shine of stainless steel or the reds, blues, or other bright colors, your options are limited.

Downsides

Hard-anodized aluminum cookware can be used in the oven, but due to the non-stick coating, it can’t withstand extremely high temperatures. Maximum oven-safe temperatures vary by manufacturer, but most are around 450°F.

The hard-anodized aluminum exterior is durable and will last a lifetime, but, unfortunately, the non-stick coating will wear down. Most non-stick hard-anodized aluminum pans need to be replaced every three-to-five years when the surface wears down and loses its effectiveness.

This cookware isn’t compatible with induction stovetops unless a steel plate is bonded to the bottom. Examples include the All-Clad HA1 collection (view on Amazon), but those options are rare.

As I mentioned, the aesthetic options are fairly limited. You can find a few with colored exteriors, such as the Anolon Advanced collection (view on Amazon), but most are single-toned dark gray.

Hard-anodized aluminum cookware is more expensive than non-anodized aluminum options but still cheaper than stainless steel.

Stainless Steel vs. Hard-Anodized Aluminum: Key Differences

Now that you know the basics of stainless steel and hard-anodized aluminum cookware, let’s explore their key differences.

Cooking Performance

Performance is often the most prominent consideration when choosing the type of cookware to invest your money in. Here’s a quick overview of performance in both categories, starting with stainless steel.

Due to its non-reactive steel surface and heat-conductive core materials (usually aluminum), stainless steel is the ultimate all-purpose cookware. You can use it for searing, browning, sautéing, boiling, braising, and more.

It heats up fast and evenly and responds to temperature changes quickly, giving you excellent control.

Stainless steel can be used on just about any cooking surface (including induction stovetops), in the oven, and under the broiler.

Because stainless steel doesn’t include a non-stick coating, it’s longer-lasting and doesn’t pose any health risks when cooking at high temperatures.

Its biggest weakness is eggs, delicate fish, and other foods prone to sticking. However, you can avoid this issue with proper preheating and the use of quality oil or butter.

Why does food stick to stainless steel pans

As stainless steel is a grained metal, avoid using salt before the water is boiling. I’m not saying you can’t salt your water, just make sure to wait until it has come to a rolling boil. If you don’t, the cookware runs the risk of pitting. 

Hard-anodized aluminum is highly-conductive, which makes it an excellent material for cookware.

It heats up quickly and evenly, so you’ll never have to deal with cold spots or inconsistent temperatures.

Since hard-anodized aluminum cookware has a non-stick cooking surface, you don’t need a ton of oil, butter, or fats to prevent sticking, and it requires far less cleaning and maintenance than stainless steel.

Unlike stainless steel, cooking eggs and other delicate foods is easy with hard-anodized aluminum. The non-stick surface makes it easy to flip and slide these ingredients.

The metal is non-porous, and therefore won’t change the flavor of your food and carries a low risk for pitting or other kinds of surface damage.

The anodizing process makes it non-reactive, meaning it won’t change the flavor of your food when you cook with acidic ingredients, even if the non-stick surface is worn down.

That said, there are some limitations. Hard-anodized aluminum can’t be used in the oven at extremely high temperatures (above 500°F), and it’s not compatible with induction stovetops.

Also, since the cooking surface is slick, it’s not the best option for searing and browning. Sticky surfaces, like stainless steel, keep the food and heat in close contact and aid in forming a crust. It’s more difficult to get that golden-brown crust on steaks, burgers, and other meats with hard-anodized aluminum.

Cleaning and Maintenance

Stainless steel usually requires a bit more maintenance than its aluminum cookware counterparts.

For best results, remove stainless steel cookware from the heat source immediately after use so that oils and fats don’t sear into the pan. Soak before cleaning to loosen bits of stuck-on food, and scrub with a soft sponge and mild dish soap.

Avoid putting still-hot stainless steel cookware into cold water. Such a quick temperature change can warp the metal.

Many stainless steel products are marketed as being dishwasher-safe, but I don’t recommend it. Always hand-wash this type of cookware.

Overall, stainless steel requires a little more love and attention to maintain. You’ll have to decide for yourself if it is worth the extra effort.

In comparison, hard-anodized aluminum is low-maintenance. It should always be hand-washed, but you’ll find that it doesn’t usually need to be soaked.

Because of the non-stick coating, never scrub it with abrasive sponges or pads. Doing so can compromise the non-stick coating.

Durability

Stainless steel cookware is the more durable option because it’s resistant to denting, warping, and corrosion.

Stainless steel is also heavier with a natural resistance to staining.

Because stainless steel cookware doesn’t have a non-stick coating and minor scratches don’t impact its performance or integrity, it can last a lifetime. This is why it’s easy to justify high prices for premium brands like All-Clad and Made In.

Hard-anodized aluminum can last a lifetime as well, but due to its non-stick coating, hard-anodized aluminum cookware usually needs to be replaced after five years or so.

Most home cooks wouldn’t consider the effort and cost of resurfacing the cookware worth it. It’s simply easier to buy a new product when the old one wears out.

As with any cookware product, be it stainless steel or hard-anodized, the longevity and durability largely depend on the level of care and maintenance you give them.

Price

The price points for either cookware option vary—the brand, manufacturer, and construction process, all impact the cost. Make sure to take some time to do some comparison shopping. 

Some key considerations:

  • In general, stainless steel is pricier than hard-anodized aluminum.
  • Stainless steel with a copper core (in either three, five, or seven-ply form) is the most expensive option. For example, All-Clad Copper Core (view on Amazon).
  • Prices increase with the level of quality and craftsmanship.
  • Even the highest-tier hard-anodized aluminum cookware is cheaper than its stainless steel counterpart.
  • If you can, pay a bit more upfront for quality construction. For stainless steel, this means buying fully-clad rather than pans with an impact-bonded base. And for hard-anodized aluminum, this means buying heavy-gauge, which is the thickness and most durable. It will save you time, money, and frustration in the long run.
