Non-stick pan

What it cannot do

A non-stick coating stops food bonding to the pan. That is exactly what you want for an omelette and exactly what you do not want when you are trying to build a fond — the browned deposits that stick to a pan are the basis of every pan sauce and gravy, and a non-stick pan produces none.

The coating also limits the temperature. Most manufacturers advise against high heat, and coatings degrade above roughly 250°C. That rules out a proper sear, which needs a pan hotter than the coating should go.

So a non-stick pan cannot brown well, cannot make a pan sauce, and should not be used for searing. None of that is a fault; it is simply not what the pan is.

What to use it for

Eggs

Omelettes, scrambled, fried. The single best reason to own one.

Pancakes and crêpes

Even release, no sticking, no seasoning to maintain.

Delicate fish fillets

Where a stainless pan risks tearing the flesh.

Reheating

Low-fat reheating without adding oil.

Not for

Searing, stir-frying, anything acidic that needs reducing hard, anything you want a sauce from, anything going into a hot oven.

Making one last

• Never on high heat. Medium at most. Overheating is what destroys coatings fastest.
• Never heat it empty. An empty non-stick pan reaches damaging temperatures within a minute.
• Wood, silicone or plastic utensils only. One metal spatula can undo years of care.
• Hand wash. Dishwasher detergent is abrasive and degrades the coating.
• Do not stack them without something between, or they scratch each other in the cupboard.
• Treat it as a consumable. Even well looked after, a non-stick pan has a life of a few years. Buy a moderately priced one and replace it, rather than buying an expensive one and mourning it.

When to replace it

Replace it when food starts sticking despite proper use, when the coating is visibly scratched through to the metal, or when it is flaking or blistering.

A worn non-stick pan is not merely less convenient — it is worse than a plain pan, because it neither releases food nor develops fond. At that point it is doing no job at all.

On safety: modern coatings are regarded as safe in ordinary use, and the concerns people remember relate to overheating well beyond normal cooking, and to manufacturing chemicals phased out some years ago. Follow the manufacturer's temperature guidance, do not heat pans empty, and if a coating is flaking, replace the pan. For anything beyond that, consult current food-safety guidance rather than a cooking site.

The coatings, and what each will take

Not all non-stick is the same material, and the differences decide what temperature and what utensils are safe.

PTFE

The classic non-stick. Slipperiest, and it degrades above a moderate-high heat. Never preheat it empty.

Ceramic

A silica-based coating. Tolerates higher heat and loses its slipperiness faster — often within a year of regular use.

Seasoned cast iron

Not a coating but a polymerised oil layer. Effectively non-stick, tolerates any heat, and repairs itself with use.

Carbon steel

The same principle, lighter and more responsive. The professional answer for eggs and crêpes.

Enamelled cast iron

Not non-stick at all, despite the smooth surface. Good for braising, poor for eggs.

Utensils

Wood, silicone or nylon on any coating. Metal ruins PTFE and ceramic in a single careless stir.

Dishwashers

Shorten the life of every coating. Wash by hand.
