Eggs stick to the pan because their proteins bond with the cooking surface as they set, and the bond is stronger when the pan is too cool, there is too little fat or you move the eggs too soon. That means you can fry an egg without a non-stick coating: preheat, turn the heat down, use enough butter or oil, then leave it alone. If a non-stick pan that used to work has started sticking, the pan itself is often the problem.
Key points
- Egg proteins bond with the metal; a properly preheated pan and enough fat keep that bond in check.
- Uncoated pans (stainless steel, cast iron, carbon steel, titanium): preheat empty, lower the heat, then add fat.
- Non-stick pans: never heat them empty on high; a medium heat is enough.
- If eggs stick in a clean non-stick pan with a little fat on a medium heat, the coating is usually worn.
Below is a step-by-step method for fried eggs, scrambled eggs and omelettes, for each type of pan. For sticking in general, see our guide on why food sticks to your pan.
Why do my eggs stick?
The Royal Society of Chemistry explains that protein-rich foods such as eggs are particularly prone to sticking, because proteins can form complexes with metal atoms such as iron. Once the surface of the food is hot enough to react, sticking stops being a problem, which is why preheating matters so much.
- The pan is too cool: the egg cooks slowly and welds itself to the base.
- The pan is too hot: Lodge, the American cast iron maker, warns that a cooking surface that is too hot can make scrambled eggs stick.
- The eggs are fridge-cold: Lodge notes that cold foods tend to stick to hot surfaces, and French cookware maker Cristel lists ingredients straight from the fridge as a cause of sticking.
- There is not enough fat: Which? points out that with stainless steel you need to add some fat, unlike a non-stick pan.
- You move them too early: until the white has set, it tears when you lift it.
- The coating is worn or dirty: a baked-on film of grease or a tired non-stick surface makes eggs stick too.
How to set up each type of pan for eggs
| Pan | Preheating | Fat | Heat for eggs |
|---|---|---|---|
| Non-stick (PTFE or ceramic), in good condition | Never empty on high (BfR, Stiftung Warentest) | A little butter or oil; no non-stick sprays (Tefal) | Medium |
| Stainless steel | Empty, medium heat, until water droplets glide | Generous (Cristel) | Lower it after preheating |
| Cast iron, carbon steel | About 5 minutes on medium-low (Lodge) | Generous (Lodge) | Medium-low |
| Uncoated titanium | As for stainless steel, patiently on medium | Butter or oil | Lower it after preheating |
Eggs sticking to a non-stick pan
A non-stick pan in good condition is the easiest option for eggs. Tefal gives 140 to 195 °C as the ideal temperature for its frying pans and says high heat barely shortens cooking time while risking damage to the coating. Germany's Federal Institute for Risk Assessment (BfR) advises never heating coated pans empty at high temperature.
How to stop eggs sticking to a stainless steel pan
It all comes down to preheating. Cristel suggests heating the empty pan over a medium heat, around two thirds of full power, for two to three minutes. Then flick in a few drops of water: if they sizzle away, wait; if they bead up and glide, the pan is ready. Lower the heat before adding the fat. Our guide to the water droplet test explains how to read it.
Cast iron and carbon steel
Lodge preheats its cast iron for about five minutes on medium-low, then melts a generous pat of butter. Seasoning does the rest: French maker de Buyer explains that the darker a carbon steel pan becomes, the less food sticks. If eggs stick in a new or freshly scrubbed pan, start by re-seasoning it.
Uncoated titanium
Titanium conducts heat about as well as stainless steel (roughly 16 to 22 W/m·K, against 14 to 16 W/m·K) and has no non-stick layer. Use the stainless steel method: patient preheating, lower heat, then fat.
Fried eggs, scrambled eggs and omelettes: step by step
For uncoated pans. With non-stick, skip the empty preheat.
Tip: GOV.UK's home food fact checker says eggs are ideally kept in the fridge, as temperature changes can cause condensation that lets Salmonella get into the egg more easily. Rather than leaving eggs out for hours, crack them into a bowl while the pan preheats.
Fried eggs
- Preheat the empty pan over a medium heat until water droplets glide, then let them evaporate.
- Turn the heat down a notch, add butter or oil and swirl.
- Slide the egg in from the bowl.
- Leave it. Lodge cooks a sunny side up egg for 1 minute uncovered, then 1 to 2 minutes covered so the top sets.
- Slide a spatula flat under the edge. If the white clings, wait.
Scrambled eggs
- Beat the eggs in the bowl.
- Preheat as above, turn down to low-medium and add a generous knob of butter.
- Pour in the eggs and let them sit briefly. As the edges set, Lodge pulls them towards the centre so the runny egg flows into the gap.
- Repeat, then take them out of the pan straight away.
Omelettes
- Beat the eggs, preheat the pan and bring it back to a medium heat.
- Melt the butter, pour in the eggs and draw the set edges towards the centre a few times.
- When the top is almost set, slide the spatula under one half and fold.
Omelette sticking to the pan: common mistakes
- A cold pan: uncoated, the eggs will almost certainly stick.
- Heat left high after preheating: the base browns and catches before the omelette sets.
- Too little butter: a thin film of oil is not enough in stainless steel.
- Burnt butter: Cristel suggests butter for gentle cooking; for higher heat, use oil.
- Cooking spray in a non-stick pan: Tefal says never to use it.
- Metal utensils on a coating: Which? advises wooden or silicone utensils, as metal can scratch off the non-stick surface.
Baking paper, water, a lid: do the tricks work?
Baking paper in the pan: this tip is widely shared online, but we found no serious test of it. The egg cooks on the paper rather than the pan. Bacofoil says its baking paper is suitable for the oven up to 220 °C and must not come into contact with a naked flame, so it is not designed for a gas hob.
A lid: it sets the top of a fried egg without flipping, which is how Lodge uses it. It does not stop the underside sticking.
A splash of water: often suggested, not verified. We found no reliable source showing it prevents sticking, and water spits in hot fat.
When the pan is the problem
If eggs stick in a clean non-stick pan with a little fat on a medium heat, the coating has usually worn. Which? tests this by dry-frying eggs before and after vibrating pans with 500 steel nuts for 10 minutes: in the worst pans, eggs stick and the yolk breaks. In Germany, Stiftung Warentest found in January 2025 that eggs stuck early on many of the 13 PTFE-free pans in its endurance test. Rule out a baked-on film of grease first, which Tefal says must be washed off after every use. Our guide to a non-stick pan that has started sticking helps you decide, and is a scratched non-stick pan safe? covers the health question.
If you are replacing yours: a coating makes eggs easier but wears out; an uncoated pan needs the method above. One uncoated option is the Untitan pan: titanium cooking surface, uncoated, PFAS-free, with a stainless steel base that suits all hobs, including induction. The hammered surface, well preheated with a little fat, makes food easier to release; without preheating and fat, eggs stick to it too. It costs more than a basic non-stick pan, and you have 30 days to try it.
Frequently asked questions
Why do my eggs stick to the pan even with oil?
Usually the pan was not hot enough, the heat was too high afterwards, or you moved them too soon. In non-stick, a worn coating is another likely cause.
How do I stop eggs sticking to a stainless steel pan?
Preheat the empty pan until water droplets glide, lower the heat, add plenty of butter or oil, then leave the eggs until they release.
Do you need a non-stick pan for eggs?
No, but it is the easiest. In stainless steel, cast iron or titanium, eggs need preheating, fat and patience.
Why is my omelette sticking to my non-stick pan?
Either a film of grease has baked onto the coating, which a thorough clean removes, or the coating is worn and the pan needs replacing.
