Cast Iron vs. Stainless Steel
To help you decide which cookware might be best for your kitchen, here’s how cast iron and stainless steel compare in terms of key factors like cooking performance, weight, versatility, durability, and more.
Cooking Performance
Cast iron is great for holding heat, which makes it perfect for cooking things like steaks, frying, or baking dishes like cornbread. It keeps the heat steady and works well in the oven. However, it takes longer to heat up and can have hot spots if not preheated properly.
On the other hand, stainless steel heats up quickly and spreads heat evenly, which makes it better for cooking with more control, like sautéing vegetables or making sauces. Stainless steel is also good for cooking delicate foods like fish or eggs.
While cast iron develops a natural non-stick surface over time, stainless steel needs a bit more care with oil and heat to prevent food from sticking. Both materials work well, depending on what you're cooking.
Weight & Handling
When it comes to weight and handling, cast iron is much heavier than stainless steel. This extra weight gives cast iron its ability to retain heat, but it can also make it harder to handle, especially when moving it around or lifting it. It can be difficult for people with wrist issues or limited strength to manage.
Stainless steel, on the other hand, is much lighter and easier to handle. It’s more comfortable to lift, and it’s easier to maneuver during cooking. This makes stainless steel a better choice for those who prefer a lighter option.
If weight is a big concern, stainless steel might be the better choice.
Versatility
Cast iron is incredibly versatile, as it can handle everything from searing and frying to baking in the oven. Its ability to go from stovetop to oven makes it great for dishes that require both methods of cooking, like braises or casseroles.
It also works well on all types of cooktops, including induction, and even on open flames, like in camping or outdoor cooking situations. However, cast iron can be a bit tricky on glass cooktops because its rough surface may scratch the glass.
Stainless steel is also versatile, particularly when paired with a conductive core, like aluminum or copper. It works well on any stovetop, including induction, and is usually lighter and easier to clean than cast iron. Stainless steel is ideal for cooking delicate foods and tasks requiring precise control, like sautéing or making sauces.
While both materials are oven-safe, stainless steel heats up more rapidly than cast iron, which makes it suitable for quick cooking tasks such as sautéing or searing. It also allows for precise temperature control due to its ability to heat quickly and cool down just as fast.
Durability
When it comes to durability, both cast iron and stainless steel are incredibly long-lasting, but they have different strengths.
Cast iron is known for its extreme durability. With proper care, such as regular seasoning, it can last for generations and even improve over time. However, cast iron is not impervious to damage. It can crack if dropped or subjected to sudden temperature changes, such as moving a hot pan directly from the oven to a cold surface.
Cast iron also requires more attention to prevent rust, as moisture can cause damage if not dried and seasoned properly after use.
Stainless steel is also highly durable and resistant to rust, staining, and corrosion. It can handle high temperatures without warping and doesn’t require as much maintenance as cast iron. Stainless steel is tough, so it’s less likely to be damaged by impact or mishandling.
However, it can scratch and develop marks over time, especially if used with metal utensils or abrasive cleaning tools.
Maintenance
When it comes to maintenance, cast iron requires more attention than stainless steel. Cast iron needs to be seasoned regularly to maintain its non-stick surface and prevent rust. This involves applying a thin layer of oil and heating it to create a protective coating.
After each use, cast iron should be cleaned carefully, avoiding soap, as it can strip away the seasoning. It’s important to dry it immediately after washing to prevent rust from forming, and some people also prefer to lightly oil it after cleaning to maintain the seasoning.
Stainless steel is much easier to maintain. It doesn’t require seasoning or special care. It can be washed with soap and water and is usually dishwasher-safe (though you should always check manufacturer instructions). Stainless steel is resistant to rust and corrosion, and it doesn’t require the same drying precautions as cast iron.
However, it can develop water spots or discoloration over time, especially if it’s not dried properly, but these can typically be cleaned off with a gentle cleanser.
Health & Safety
In terms of health and safety, both cast iron and stainless steel are generally safe to cook with, but there are a few key differences.
One of the health benefits of cast iron is that it can add small amounts of iron to your food, which can be helpful for people with iron deficiencies ❶. However, for those who don't need extra iron, this can be a concern, as too much iron may be harmful over time.
Another point to consider is that cast iron can rust if not properly cared for, and rusting can lead to contamination of food if not cleaned off. When seasoned correctly, cast iron creates a natural non-stick coating that reduces the need for excessive oils or fats in cooking, making it a healthier choice for some dishes.
Stainless steel is non-reactive, meaning it doesn’t leach any harmful substances into food, making it very safe for all types of cooking, including acidic foods like tomatoes or citrus.
High-quality stainless steel is also resistant to rust and corrosion, which further improves its safety and longevity. There are no concerns about adding extra metals to your food, unlike cast iron, so it's a great option for those who are cautious about what they consume.
Tip: When cooking with stainless steel, using algae cooking oil can enhance the health benefits. Algae oil, rich in healthy omega-9, works perfectly in stainless steel cookware because it can withstand high heat without breaking down ❷. Additionally, because stainless steel doesn’t react with the oil, you can enjoy its health benefits without worrying about any harmful substances leaching into your food.
Cost
Cast iron is usually cheaper than stainless steel upfront. A basic cast iron pan is affordable and can last a lifetime with proper care, making it a great choice for those on a budget. It doesn’t require special materials, which keeps the price low.
Stainless steel, especially high-quality versions with layers like aluminum or copper, is more expensive. The manufacturing process is more complex, which raises the price.
However, stainless steel is a good long-term investment since it’s durable and easier to maintain. While it costs more initially, it can save money in the long run with less care and cleaning.
Cast Iron vs. Stainless Steel Verdict
After considering the key differences between cast iron and stainless steel, it’s clear that both have their advantages depending on your cooking needs. However, if you’re looking for a versatile, low-maintenance cookware option that pairs well with high-heat oils like algae oil, stainless steel is the top choice.
Stainless steel heats up fast and evenly, making it ideal for tasks like sautéing and searing. It’s light, easy to lift, and won’t rust for durable performance. Plus, it’s safe to use with acidic foods since it doesn’t react.
