A well-chosen pan can completely transform the way you cook. From the golden crust of a perfect steak to a delicate omelette sliding right off the surface—the material, temperature and condition of your cookware make a world of difference.
But why do some pans get better with age, while others gradually lose their non-stick properties? Why do professional chefs often use darkened steel pans instead of spotless, shiny new ones?
The answer lies in the properties of different metals, how they retain and transfer heat, and proper care.
One of the most fascinating techniques is seasoning—building up a natural protective layer on the metal surface. Used for generations, it allows certain pans to last for decades.
This technique has nothing to do with salt or spices. It is a process where an extremely thin layer of fat is applied to the metal surface and heated until it transforms into a durable protective coating.
When heated, a chemical process called polymerisation takes place. The fat molecules bind together to form a relatively hard layer that bonds to the metal.
This is not just simple oiling. A well-seasoned layer should never feel greasy or sticky to the touch. It serves three vital functions: it protects the iron from rust, reduces sticking, and makes cleaning easier.
Interestingly, with proper use, this protective coating develops and improves over time. Unlike factory-applied non-stick coatings, it can be restored whenever it wears down.
However, it is important to know that not all pans should be seasoned. For some materials, the process is unnecessary, and for others, high heat can damage the surface.
Cast iron is one of the most durable materials in the kitchen. Heavyweight and exceptional at retaining heat, it is perfect for searing meat, roasting potatoes, cooking vegetables, and even baking home-made bread.
When you drop a cold piece of meat into a pan, the surface temperature drops. Heavy cast iron holds a vast reserve of heat, maintaining a temperature high enough to create a beautiful crust.
This is where the Maillard reaction happens—a sequence of chemical reactions between amino acids and sugars that creates the signature brown colour and rich flavour of seared meat.
However, cast iron heats up relatively slowly and reacts slowly to temperature adjustments. That is why it is not always the best choice for delicate sauces.
First, wash the pan with warm water and a little washing-up liquid. Dry it thoroughly, then place it over low heat for a moment to evaporate any remaining moisture.
Apply a few drops of refined sunflower or rapeseed oil, spreading it over the entire bare metal surface with kitchen paper.
Then, wipe off almost all the oil. The pan should look practically dry.
Place it upside down in an oven preheated to around 200–230°C for about an hour. Make sure all components are oven-safe and keep the kitchen well ventilated. Adjust the temperature according to the manufacturer's guidelines.
Allow the skillet to cool down gradually. Repeat the process two or three times if needed.
How can you tell if it worked? The surface should be dry, fairly smooth, and non-sticky. A dark colour is characteristic of a well-seasoned pan, but colour alone does not guarantee quality.
This is one of the most common misconceptions.
Modern, mild washing-up liquids will not strip away a properly polymerised seasoning layer during normal washing.
The real enemies of cast iron are prolonged soaking, moisture, and leaving food debris on the surface.
Top tip: If burnt bits remain after cooking, pour in a little water, warm it up briefly, and gently scrape them off with a wooden spatula. Dry the pan thoroughly afterwards.
Carbon steel is especially popular in restaurant kitchens. These pans combine some of the benefits of cast iron with faster response times to heat changes. They are generally thinner and lighter than a cast iron skillet of a similar size.
They are ideal for steaks, omelettes, pancakes, fried eggs, and high-heat Asian dishes.
It allows you to transition quickly from high to medium heat, and once well seasoned, food releases effortlessly.
Unlike pans with factory non-stick coatings, plain carbon steel can be used for high-heat searing.
New pans often come with a factory coating of wax or oil designed to prevent rust during storage. Remove this coating first according to the manufacturer's instructions.
After washing and drying thoroughly, heat the pan gradually. Apply an extremely thin layer of oil and continue heating until the fat begins to polymerise.
Some models can be seasoned on the hob, while others require an oven. Keep the area well ventilated and follow the instructions for your specific pan.
A new pan is usually silver-grey, but after a few uses and seasonings, it will take on golden, brown, bluish, and almost black tones.
This is completely normal and stems from heating the metal as well as building up the protective coating. A darkened pan is not dirty or damaged—it is a natural part of developing its patina.
Fun fact: Patina does not have to be perfectly uniform. A pan with brown, black, and grey patches will perform brilliantly as long as the surface is dry, smooth, and rust-free.
Tomatoes, vinegar, wine, and lemon juice can gradually weaken the seasoning layer, especially when it is fresh.
Adding a splash of lemon juice at the end is fine for a well-maintained pan, but simmering tomato sauce for hours is not its best use.
For those recipes, stainless steel or enamelled cookware is a better choice.
Stainless steel is prized for its durability, corrosion resistance, and versatility. Unlike cast iron and carbon steel, it does not require traditional seasoning with oil and heat.
This is due to chromium, which forms an ultra-thin protective oxide layer over the metal.
Most often, sticking comes down to temperature, oil, moisture on the food, or flipping too early. For many dishes, it helps to preheat the pan over medium heat before adding the oil.
Pat meat dry with kitchen paper before putting it in the pan. Excess moisture prevents a good crust from forming.
Once the meat hits the pan, resist the urge to move it. As a crisp crust forms, it will naturally release from the surface.
You may have seen videos where a splash of water glides around like a tiny marble on a hot pan. This is called the Leidenfrost effect. At high temperatures, a thin cushion of steam forms between the drop and the surface, letting the water slide around.
The test shows the pan is hot, but that does not mean it is the right temperature for every dish. For delicate foods like eggs, that temperature would be far too high.
After searing meat, browned bits are often left stuck to the bottom of the pan. Known as the fond, these bits hold concentrated flavours from the searing process.
Instead of scrubbing them away, professional chefs pour in a little stock, water, or wine to dissolve them—a technique known as deglazing.
This liquid becomes the foundation for a rich pan sauce with butter, mustard, cream, or herbs.
Top tip: If you love making pan sauces after searing meat, stainless steel is one of the most practical options.
Non-stick pans are handy for eggs, pancakes, fish, and other delicate foods.
Most traditional non-stick coatings are PTFE-based, famously known by the brand name Teflon.
They do not require seasoning with oil and heat.
PTFE coatings are designed for use within specific temperature limits. Severe overheating can cause them to degrade and emit harmful fumes.
That is why you should never leave an empty non-stick pan on a high burner.
Stick to low-to-medium heat, avoid overheating, and follow the manufacturer's temperature guidelines.
Over time, the coating wears down from scratches, high heat, and harsh cleaning.
Sometimes the issue is simply build-up from burnt oil residue, which can be removed with gentle cleaning. However, if the coating is physically damaged, home seasoning will not restore it.
When should you replace it? If the coating is flaking, deeply scratched, or visibly damaged, it is time for a new pan.
Ceramic pans are popular for their smooth surface and easy cleanup.
Most modern ceramic pans are not made entirely of ceramic; they are metal pans with a special coating, often silicon-based.
They do not require traditional seasoning.
One common culprit is a thin layer of burnt fat building up on the surface. This happens when cooking frequently at high temperatures, especially with generous amounts of oil.
Over time, the ceramic coating itself can naturally lose some of its non-stick release.
To extend its lifespan, stick to moderate temperatures, soft sponges, and non-abrasive utensils.
Top tip: A tiny smear of oil or butter is usually enough for cooking eggs and pancakes. Avoid unnecessary high heat.
Although made of cast iron, this cookware features a smooth enamel coating that shields the metal from moisture, eliminating the need for traditional seasoning and baking.
Enamelled cast iron excels at stews, soups, slow-cooked meats, and recipes with tomato sauces.
Unlike bare cast iron, undamaged enamel creates a complete barrier between food and metal.
This allows for long, slow cooking with tomatoes, wine, and other acidic ingredients without stripping away polymerised seasoning.
The main rule is to avoid extreme thermal shock and heavy impacts that could chip or crack the enamel.
Never heat an empty enamelled pot on high unless the maker explicitly states it is safe.
Aluminium pans are staples in both home and commercial kitchens because they are lightweight, affordable, and heat up fast. Aluminium conducts heat significantly better than stainless steel, distributing heat evenly across the base.
This makes them great for veggies, eggs, pancakes, fish, and any dish where quick temperature control matters.
Interestingly, aluminium is not just used on its own. It is frequently layered inside high-quality stainless steel cookware. Steel provides a tough, non-reactive exterior, while the aluminium core ensures even heat distribution.
Unlike cast iron and carbon steel, aluminium does not require traditional heat-and-oil seasoning.
When exposed to air, aluminium naturally forms a microscopic oxide layer. This layer prevents further oxidation and offers basic protection against corrosion.
However, this does not make raw aluminium non-stick. Food will stick to untreated aluminium pans if the temperature or amount of cooking fat is off.
Important: Some manufacturers recommend specific priming procedures for their aluminium pans before first use. Always follow the guidelines for your specific pan rather than applying cast iron techniques automatically.
Anodising is an electrochemical process that thickens and hardens the natural oxide layer on aluminium.
The resulting surface is much tougher and more resistant to wear and corrosion than plain aluminium.
Hard-anodised aluminium pans are especially popular. They feature a thick, durable oxide layer and often have a distinctive dark grey or graphite finish.
Here is the key detail: Anodised aluminium is not automatically non-stick.
Some pans feature just the anodised metal surface, while others carry an additional PTFE or ceramic non-stick coating. That extra coating determines how you should use and clean the pan.
Copper pans are prized treasures in professional kitchens. They stand out not only for their stunning appearance, but for their exceptional thermal conductivity.
Copper conducts heat far better than stainless steel, spreading heat rapidly and evenly across the pan. Turn the burner up or down, and the pan responds almost instantly.
This makes copper cookware ideal for delicate sauces, caramel, melted chocolate, custards, and any recipe where a few degrees can make or break the outcome.
Copper pans lined with stainless steel do not require seasoning.
Tin-lined copper pans require careful heat control, as tin has a low melting point—around 232°C.
Fun fact: Tarnish on the exterior copper surface is a natural result of oxidation and does not mean the pan is ruined.
The greatest advantage of copper is pin-point temperature control.
When making emulsion sauces like Hollandaise or Béarnaise, excessive heat will cause the sauce to split. A copper pan responds immediately when you turn down the flame, saving the sauce.
It is equally valuable for caramelising sugar, where the line between golden caramel and burnt sugar is a matter of seconds.
However, copper pans are not automatically superior for every dish. They demand extra care, specific maintenance, and are usually much pricier than stainless steel or aluminium options.
There is no need to buy specialty or expensive oils. For home seasoning, refined sunflower oil, avocado oil, and grapeseed oil are excellent choices. These fats polymerise effectively under proper heat.
Flaxseed oil is also popular, but under certain conditions, it can form a brittle coating that flakes off later.
The smoke point indicates the temperature at which an oil begins to visibly smoke under set conditions.
However, successful seasoning depends on the oil's chemical structure, application thickness, temperature, and heating time.
Therefore, the highest smoke point does not automatically deliver the best results. The cardinal rule remains: apply the oil in an ultra-thin layer.
Even the right pan can yield poor results if basic rules are missed.
Too much oil. Instead of a hard, protective coat, you end up with a sticky, uneven film. Applying several whisper-thin layers works far better than one thick coat.
Insufficient heat. If the heat or timing falls short, the oil will not fully polymerise, leaving the surface tacky.
Seasoning a damp pan. Trapped moisture prevents the oil from bonding properly and promotes rust underneath.
Seasoning the wrong pan. Traditional oil seasoning should never be applied to PTFE, ceramic, or enamelled pans.
Aggressive scrubbing. Harsh abrasives can strip away your seasoned layer. If this happens, don't worry—the pan isn't ruined, but you will need to re-season it.
Sudden temperature drops cause thermal shock, which can warp the pan base or crack the metal. Be extra cautious with cast iron and carbon steel. Furthermore, soaking these materials for long periods encourages rust. The best approach is to let the pan cool down naturally, wash it with warm water and a mild washing-up liquid, dry it thoroughly, and apply a tiny smear of oil if needed.
For cast iron and carbon steel pans, daily care makes all the difference. Allow the pan to cool after cooking, then wash with warm water and a soft brush or sponge. Use a splash of mild washing-up liquid if necessary.
Dry immediately after washing. If needed, pop it over low heat for a minute to evaporate lingering moisture.
Apply a tiny drop of oil for added rust protection during storage, wiping off any excess.
Never leave cast iron or carbon steel pans to soak, and keep them out of the dishwasher.
Surface rust on bare cast iron or carbon steel does not mean it belongs in the bin.
For light surface rust, simply scrub the affected spots with a suitable brush, wash, and dry thoroughly.
Afterwards, re-season the cleaned surface. If corrosion is deep or structural damage is evident, inspect the pan carefully before cooking with it again.
Note: Rust is not the same as natural dark patina. Patina is a tough, protective coating, whereas rust is reddish-brown and flakes off when touched.
You do not need to go through the full seasoning process after every meal.
With proper care, cast iron and carbon steel retain their protective seasoning for a long time.
Re-seasoning is only needed if rust appears, large patches wear away, or the protective coating gets damaged.
Even a beautifully seasoned cast iron pan is not identical to a synthetic non-stick pan. Sticking depends on surface temperature, oil usage, food moisture, and undisturbed cooking time.
For instance, cold meat with surface moisture is prone to sticking initially. Once a proper crust sears onto the bottom, it will release naturally.
For eggs, use moderate heat and plenty of cooking fat.
Top tip: Do not try to solve sticking by cranking up the heat. Often the real solution is the exact opposite—lower heat, drying food thoroughly beforehand, or giving it an extra moment to sear before turning.
Different materials bring distinct advantages, and matching the material to the dish elevates your cooking results.
For steaks and perfectly seared meats, cast iron and carbon steel are king. They deliver an intense sear and a delicious crust while locking in juices.
For omelettes and fried eggs, non-stick or well-seasoned carbon steel pans are ideal. They let eggs slide free without tearing.
For pancakes, non-stick and carbon steel pans work brilliantly. At the right temperature, they deliver even browning and easy flipping without sticking.
For crispy-skinned fish, stainless steel and carbon steel excel. With dry fish skin, a well-heated pan, and enough oil, the skin crisps up beautifully without tearing during the flip.
For tomato sauces and acidic dishes, reach for stainless steel or enamelled cast iron. These surfaces resist acids in tomatoes, wine, and lemon juice during long simmers.
For high-heat sautéed vegetables, carbon steel is extremely practical. It responds quickly to temperature tweaks and allows for intense searing while keeping veggies crisp-tender.
For slow-cooked meats, stews, and braises, enamelled cast iron is unmatchable. It retains heat effortlessly over long, slow simmers, tenderising meat and building deep flavours.
For delicate sauces, caramel, and custards, lined copper pans or multi-clad stainless steel pans are best. They give you precise temperature control so sensitive mixtures won't scorch or split.
Top tip: You don't need every pan under the sun. For most home kitchens, a solid setup is one good stainless steel pan for meats, veggies, and sauces; one non-stick pan for eggs; and one cast iron or carbon steel pan for heavy searing.
A heavy pan holds plenty of heat, but that doesn't make it right for every job.
For delicate dishes requiring quick heat adjustments, a lighter, more responsive pan is far easier to handle.
Thin pans develop hot spots easily, especially over high-power burners.
Quality multi-ply pans sandwich aluminium between layers of stainless steel to spread heat evenly across the entire surface.
Induction uses electromagnetic fields to heat compatible metal cookware.
Cast iron and most carbon steel pans work natively. Many stainless steel pans work too, but not all.
Aluminium and copper pans require a special magnetic base to function on standard induction hobs.
A quick test is to hold a magnet to the base: if it sticks firmly, the pan will likely work, though checking the maker's label is safest.
Even if the pan body handles high heat, plastic parts, silicone grips, or wooden handles may have much lower temperature limits.
Always check the maximum oven temperature rating for the entire pan before baking with it.
Stacking pans directly on top of each other causes the bottom of one pan to scratch the interior coating of another.
This is especially critical for non-stick and ceramic coatings.
Placing felt pan protectors or soft cloths between stacked pans is an easy way to prevent mechanical wear.
Every material has its own strengths and quirks. Cast iron and carbon steel rely on a renewable protective seasoning layer. Stainless steel requires proper heat and oil control, while ceramic and non-stick coatings demand lower heat and gentle handling.
There is no single best pan for every job. Knowing when to reach for each material—and how to care for it—is what really counts.
A great pan isn't necessarily the most expensive or the shiniest. It's the one that matches how you cook, cared for properly.
Because a reliable pan isn't just kitchen gear—it's an essential part of cooking well.
