Why food sticks to your pan (and how to stop it)

Food sticks to a pan because the proteins and starches in it bond with the metal surface as they heat up, and they bond more readily when the pan is too cool, the food is wet or cold, or there is too little fat. If a non-stick pan that used to work well has started sticking, the cause is usually a baked-on film of grease or a worn-out coating. In almost every other case, four habits fix it: preheat properly, use a little fat, cook dry food that is not fridge-cold, and wait before you turn it.

This guide walks through the causes, helps you diagnose the problem for your type of pan, and sets out a method that works on any uncoated pan, whether stainless steel, cast iron, carbon steel or titanium. It finishes with practical advice for eggs, fish, meat, pancakes and potatoes.

Why does food stick to my pan?

The Royal Society of Chemistry explains sticking as chemistry: bonds form between the food and the material of the pan, ranging from weak van der Waals forces to proper chemical bonds. Protein-rich foods such as eggs, cheese, fish and meat are particularly prone to it, because proteins can form complexes with metal atoms such as iron.

The same source explains why sticking does not last. Once the surface of the food gets hot enough to react with something else, sticking stops being a problem, which is exactly what happens when meat browns. That browning is what Germany's Federal Institute for Risk Assessment (BfR) calls the Maillard reaction, which takes place when food is baked, roasted or fried. Fissler, the German cookware maker, puts it simply: once a crust has formed, the food releases from the pan by itself. Pull it before then and you tear the crust off.

The most common causes

• The pan is not hot enough. Cristel, a French stainless steel maker, names insufficient preheating as the main culprit.
• The pan is too hot. The outside burns before the inside cooks, and residue scorches onto the base. Oil that is smoking is a clear sign to turn the heat down.
• The food is straight from the fridge. Cold food cools the contact surface, and Cristel lists it among the usual mistakes.
• The food is wet. While there is water in the pan, the temperature stays close to 100 °C, as the BfR notes. The food steams instead of searing.
• There is not enough fat. Which? points out that stainless steel has no natural non-stick coating, so oils and fats are what prevent burning and sticking.
• You turned it too soon. Cristel allows three to four minutes for meat to form a crust before turning.
• The surface is damaged or dirty. A worn coating, a baked-on grease film or damaged seasoning all change how a pan behaves.

Diagnosing the problem by type of pan

The causes are similar for every pan, but the fix depends on the material.

Non-stick pan sticking (PTFE or ceramic)

When a non-stick pan stops releasing food, there are two very different explanations, and only one of them can be fixed.

A baked-on film of grease. Tefal explains in its care instructions that a film of grease stays on the surface after cooking. If the pan is only wiped with kitchen paper or rinsed with water, the film is not fully removed and cooks on the next time you use it. This is fixable: Tefal suggests soaking the pan overnight in water with washing-up liquid, then gently scrubbing with a paste of bicarbonate of soda. Never use scouring powder or scouring pads.

A worn coating. Non-stick coatings wear out; that is simply how they work. Which? tests this by vibrating pans with 500 steel nuts before frying eggs again: the best pans still fry eggs well, while the worst lose some of their non-stick properties. Germany's consumer testing body, Stiftung Warentest, found in its January 2025 test that eggs stuck early on many ceramic pans during the endurance test. The German Verbraucherzentrale consumer advice service says the non-stick effect of PTFE pans fades after three to five years depending on use, and gives a shorter 1.5 to 2.5 years for ceramic coatings. We have not found a standard lifespan published by a UK body, so think in terms of a few years, depending on care.

Signs that the coating has had its day:

• visible scratches, or patches where the coating is lifting;
• an egg sticks even though the pan is clean, on a medium heat and with a little fat;
• food still sticks after a thorough clean.

What wears a coating out faster is well documented. Regular overheating weakens it, according to Tefal, which says a medium to low heat is sufficient. Stiftung Warentest advises against heating coated pans empty on a high setting. Which? recommends handwashing even dishwasher-safe pans, using wooden or silicone utensils rather than metal, and protecting the surface when pans are stacked. On ceramic pans, extra virgin olive oil turns resinous at high temperatures and destroys the non-stick effect, says Stiftung Warentest.

Whether scratches matter for your health is a separate question. The BfR does not expect swallowed PTFE particles to cause health effects; we cover the evidence and the open questions in our article on cooking with a scratched non-stick pan, and what ceramic coatings are made of in are ceramic pans safe?.

Why does everything stick to my stainless steel pan?

Because stainless steel has no natural non-stick coating. The release comes from how you cook, not from the pan. People who move from non-stick to stainless steel and keep the same habits (cold pan, little fat, food moved around early) find that everything sticks. The pan is not faulty; it just needs a different approach.

Preheating is the key. Which? recommends heating the empty pan for a minute or two before cooking, and Cristel suggests two to three minutes over a medium heat so the heat spreads, then checking the temperature with a few drops of water.

What is the water on pan trick?

It is a quick way to tell when an uncoated pan is hot enough. Flick a few drops of water into the preheated pan and watch what they do:

• The water sizzles and evaporates: the pan is not ready yet, says Fissler.
• The water beads up and glides across the surface: the pan is ready (Which?).

The gliding bead is the Leidenfrost effect. The underside of the drop vaporises instantly and the rest floats on a cushion of steam. Physicists at Emory University in the US showed in 2021 that this vapour layer collapses below about 140 °C. The exact point depends on the surface, though: research by Wakata and colleagues (2023) found that the Leidenfrost temperature is higher on rougher surfaces and on poor heat conductors such as stainless steel than on aluminium. So the test tells you the pan is in the right range, not a precise number, and that is all you need. Wipe or let the drops evaporate, add your fat, and start cooking. We explain the physics and the common misreadings in our guide to the water droplet test for pans.

Cast iron or carbon steel pan sticking

Bare cast iron and carbon steel have no natural release when new. They get it from seasoning, a thin layer of oil heated until it polymerises, which also protects the iron from rust. If one of these pans starts sticking, the seasoning is usually too new or has been damaged by the dishwasher, heavy scrubbing, soaking or acidic food. French maker de Buyer explains that seasoning builds with use: the darker the pan becomes, the less food sticks. The fix is to re-season and then cook with fat often, as set out in our guide on how to season a pan.

Titanium pan sticking

First, check what you actually have. Many pans sold as ‘titanium’ have a non-stick coating: Tefal describes its Titanium Excellence coating as reinforced with titanium particles, and Tefal states that its non-stick coatings contain PTFE. If that is your pan, everything in the non-stick section above applies.

An uncoated titanium cooking surface behaves like stainless steel. Titanium conducts heat about as well as stainless steel (roughly 16 to 22 W/m·K, against about 14 to 16 W/m·K for 18/10 stainless steel) and has no non-stick layer. When food sticks, the cause is almost always too little preheating, too little fat, or a heat left too high after preheating. Seasoning is not essential for titanium: follow the manufacturer's instructions, bearing in mind that preheating with a little fat matters more. For an honest look at the material's strengths and limits, see our titanium frying pan guide.

Step by step: how to stop food sticking in any uncoated pan

This method is for stainless steel, cast iron, carbon steel and uncoated titanium. It is not for non-stick pans: the BfR advises against heating them empty, and Tefal says a medium to low heat is enough for them.

1. Take food out of the fridge in good time. Meat, fish and eggs should not go straight from the fridge into the pan.
2. Pat it dry. Use kitchen paper on meat, fish and vegetables. Water holds the pan temperature down near 100 °C.
3. Preheat the empty pan over a medium heat. One to two minutes (Which?) to two to three minutes (Cristel), depending on the pan and hob.
4. Do the water test. If the drops sizzle away, wait. If they bead up and glide, the pan is ready.
5. Add fat. A cooking oil suited to frying, or butter or oil for delicate food, as Cristel suggests. The oil should shimmer, not smoke.
6. Adjust the heat. Keep it up for searing meat; turn it down for eggs and fish.
7. Add the food and leave it alone. Do not overcrowd the pan: too much cold food at once drops the temperature.
8. Turn it when it releases. Nudge it with a spatula. If it still clings, give it a little longer.
9. Deglaze. Which? suggests using stock or wine to lift the browned bits from the base. You get a sauce and an easier pan to wash.

Practical cases: eggs, fish, meat, pancakes and potatoes

How to stop eggs sticking to a stainless steel pan

Eggs are the hardest test for any uncoated pan, because they are almost all protein and water. They cook perfectly well in stainless steel if you preheat the pan, then lower the heat and add butter or oil, which Cristel recommends for delicate foods such as eggs. Which? notes that with stainless steel you need to add some fat, unlike a non-stick pan where eggs cook with very little oil. Crack an egg into a cold pan with no fat and it will stick. Fried, scrambled and omelettes are all covered in our guide to stopping eggs sticking to the pan.

Fish

Fish is protein-rich and delicate. Pat it thoroughly dry, lay it in hot fat, which Cristel considers necessary for fish in stainless steel, and do not move it. Once the underside has browned, the fillet lifts without resistance and is ready to turn.

Steak and chicken

With meat, some sticking at the start is normal and useful: it is what creates the browned bits and the flavour. Cristel allows three to four minutes for the crust to form, after which the meat turns without leaving pieces behind.

Pancakes

Pancake batter is thin and spreads over a large area, with little time to brown before it sets. In an uncoated pan, you need a thoroughly preheated pan, a steady medium heat and a thin film of fat before each pancake. To be honest, if pancakes are what you make most, a good non-stick pan is easier to live with.

Fried and sautéed potatoes

Potatoes release starch that clings to the base of the pan. Dry raw slices well, put them into hot fat and only turn them once the first side is golden. That also fits the Food Standards Agency's ‘Go for Gold’ advice: acrylamide forms when starchy foods are cooked above 120 °C, and the FSA recommends aiming for a golden yellow colour or lighter when frying or roasting them.

How to clean a pan when everything has stuck

Patience works better than force. By material:

• Stainless steel and titanium: add a little water to the still-warm pan to loosen the residue. For stubborn marks, Which? suggests a paste of bicarbonate of soda and water, or soaking the pan first.
• Non-stick: let it cool, soak it, then clean with a soft sponge. No abrasives, which damage the coating.
• Cast iron and carbon steel: avoid soaking and the dishwasher, both of which strip seasoning and cause rust (Lodge). Dry straight away, oil lightly, and re-season if needed.

Methods, products and mistakes to avoid are all in our guide on how to clean a burnt pan.

Care that stops sticking before it starts

• Wash properly after every use. A grease film left behind cooks on next time (Tefal).
• Keep scourers away from coatings and seasoning. Both are easily damaged.
• Handwash non-stick pans and protect them in storage. A tea towel between stacked pans helps (Which?).
• Dry and oil cast iron and carbon steel after each wash.

For titanium specifically, cleaning, discolouration and day-to-day use are covered in our titanium pan care guide.

When a non-stick pan sticks, the coating is often finished

If your non-stick pan still sticks after a thorough clean, it is probably time to replace it. That raises the question of whether to buy another coated pan. It depends on how you cook: non-stick is the easiest to use but wears out; uncoated pans need the method above, but have no coating to wear away.

We compare these options in detail in uncoated frying pans: your real options, and the two closest metals head to head in titanium vs stainless steel frying pan. If health is part of your decision, our article on the healthiest frying pan sets out what the authorities say about each material.

One of the uncoated options is the Untitan pan: titanium cooking surface, uncoated, PFAS-free. It has a hammered surface and a stainless steel base that makes it suitable for all hobs, including induction, and comes in 26, 28 and 30 cm. The method in this guide applies to it as it stands: the hammered surface, well preheated with a little fat, makes food easier to release. You have 30 days to try it, with returns and a refund if it is not for you.

Frequently asked questions

Why does food stick to my pan?

Proteins and starches bond with the metal when the pan is too cool, the food is wet or cold, or there is too little fat. In non-stick pans, a baked-on grease film or a worn coating is the usual cause.

Why is my non-stick pan sticking?

Clean it thoroughly first, because a baked-on film of grease is enough to make it stick. If it still sticks, or it is scratched, the coating is worn and cannot be restored.

How do I stop eggs sticking to a stainless steel pan?

Preheat the empty pan until drops of water glide, add butter or oil, lower the heat, then add the eggs and leave them until they set and release.

What is the water on pan trick?

Drops of water flicked into an uncoated pan show when it is hot enough: if they sizzle away, wait; if they bead up and glide, add your fat and start cooking.
