A chicken fillet. A salmon fillet. A handful of mushrooms. You probably pan-fry every week, and yet things go wrong a little more often than you would think: the meat turns grey instead of brown, the fish sticks to the pan or the mushrooms swim in liquid.

Pan-frying is cooking food briefly and at a fairly high temperature in a pan with a little fat. The aim is a brown, flavourful crust outside and a cooked inside.

What is pan-frying?

When pan-frying, the food touches the hot bottom of the pan directly. That browns the surface. That browning is called the Maillard reaction: proteins and sugars react with each other and form hundreds of new flavour compounds.

For good pan-frying you need:

a pan that holds heat well (stainless steel, cast iron or a good frying pan);
a fat that can handle high temperatures;
food that is dry;
enough room in the pan.

Why is a hot pan so important?

In a pan that isn’t hot enough, the food releases moisture and starts to boil or stew in that moisture. No crust forms and the meat turns grey.

First the pan hot, then the fat, only then the food.

How to pan-fry well

Step 1 – Take the food out of the fridge in good time

Let a piece of beef or pork come to room temperature for about 20 to 30 minutes, but no longer. An ice-cold piece cools the pan strongly. Chicken, mince and fish stay in the fridge until just before frying.

Step 2 – Pat it dry

A wet surface evaporates first and prevents browning. So pat the food thoroughly dry with kitchen paper.

Step 3 – Heat the pan

Put the pan on medium-high to high heat and let it get properly hot. A drop of water should sizzle and dance away immediately.

Step 4 – Add the fat

Use frying fat, groundnut oil, sunflower oil or clarified butter. Ordinary butter burns quickly, so add it only at the end for flavour.

Step 5 – Add the food and leave it alone

Lay the food in the pan in one layer and leave it. Only turn it when it comes free from the pan. If it sticks, it isn’t ready to be turned yet.

Step 6 – Let it rest

After frying, put meat on a plate for a few minutes. The juices redistribute and the meat stays juicier.

The secret is in the space

A common mistake is putting too much in the pan at once. The food touches, the temperature drops and it starts steaming in its own moisture.

Fry in batches instead. It takes a few minutes more, but the difference in flavour is big.

What do you fry for how long?

Ingredient	Heat	Guide time
Chicken fillet (about 150 g)	medium-high	5 to 6 minutes per side, centre 75 °C
Steak (2 to 3 cm)	high	2 to 3 minutes per side for medium-rare
Salmon fillet with skin	medium-high	4 to 5 minutes skin side down, 1 to 2 minutes on the other side
Sliced mushrooms	high	5 to 7 minutes, salt only at the end
Fried egg	medium	2 to 3 minutes

These are guide times. The thickness of the piece and the pan determine the time. Preferably check meat and chicken with a thermometer.

Pan-frying, roasting or sautéing?

The three are close together. Pan-frying is a short cooking in a pan. With roasting or braising you brown first and then let it cook on more gently. With sautéing you keep small pieces moving.

Which pan do you choose?

The pan determines how the frying goes.

Stainless steel: holds heat well and gives a good crust, but food sticks more easily if the pan isn’t hot enough.
Cast iron: holds heat very well and is ideal for meat. It needs to be maintained and oiled.
Non-stick: handy for eggs and fish, but not suitable for very high heat. Don’t use metal utensils.
Carbon steel: a light pan that heats quickly and is widely used by chefs.

Which fat do you use?

Fat	Approx. smoke point	Use
Ordinary butter	150 °C	flavour, on medium-high heat or at the end
Clarified butter (ghee)	about 250 °C	high-temperature frying with a butter flavour
Sunflower oil	about 220 °C	everything, neutral
Groundnut oil	about 230 °C	high heat, neutral
Olive oil (extra virgin)	about 190 to 210 °C	medium-high, with flavour

The values are indicative and differ by product. A fat that smokes is too hot.

When do you salt?

Salt meat right before frying and then pat it dry again, or salt it well in advance (at least 40 minutes), so the salt penetrates and the surface dries again. If you salt somewhere in between, it draws moisture out of the meat and you have a wet surface. With mushrooms you salt only at the end, otherwise they release moisture too fast.

Pan-frying fish and vegetables

You fry a fish fillet skin side down in a hot pan, and press it flat with a spatula for the first 10 seconds so the skin doesn’t curl. Vegetables such as courgette, pepper or aubergine are fried in small batches, dry and over fairly high heat.

The most common mistakes

The pan isn’t hot enough

The food stews instead of frying and turns grey.

Solution: let the pan get properly hot before you add the food.

The food is wet

The moisture evaporates first and prevents a crust.

Solution: pat it dry with kitchen paper.

You have too much in the pan

The temperature drops and everything steams.

Solution: fry in batches.

You turn too early

The food sticks and tears.

Solution: wait until it comes free by itself.

You use the wrong fat

Butter burns and gives a bitter taste.

Solution: use a fat that tolerates heat and add butter later.

What do you do with the fond?

The brown bits on the bottom of the pan are not dirt but pure flavour. Deglaze them with a splash of wine, stock or water, scrape them loose and let it reduce. In a few minutes you have a sauce.

Practise with a chicken fillet

Take the chicken fillet out of the fridge just before frying.
Pat it dry and season it.
Heat the pan and add the fat.
Lay the fillet in the pan and leave it for 5 minutes.
Turn it and fry for another 5 minutes.
Let it rest for 5 minutes and cut it open.

Look at the crust and at the juice in the cross-section. That is how you learn what a hot pan does.

Why brown is delicious: the Maillard reaction

When food browns in a hot pan, something special happens. Proteins and sugars at the surface react with each other and form hundreds of new aroma and flavour compounds. That is called the Maillard reaction, named after the French chemist who described it. It is the reason a fried steak tastes different from a boiled one, and that roasted coffee is bitter-sweet.

The reaction starts at about 140 to 150 °C at the surface, and works best on a dry surface. Moisture keeps the temperature around 100 °C, and above that the browning only gets going once the water is gone. That is why patting dry is so important.

Frying a steak: step by step

Take the steak out of the fridge 30 minutes before frying.
Pat it dry and season it with pepper and salt.
Heat a heavy pan until it is hot and add a neutral oil.
Lay the steak in the pan and leave it alone for 2 to 3 minutes.
Turn it once and fry the other side for 2 to 3 minutes.
Add a knob of butter, a sprig of thyme and a clove of garlic and spoon the butter over the meat.
Let the steak rest for 5 minutes before cutting.

Doneness	Core temperature	Approx.
Rare	about 50 °C	1.5 minutes per side
Medium-rare	about 55 to 58 °C	2 to 3 minutes per side
Medium	about 60 to 63 °C	3 to 4 minutes per side
Well done	from 70 °C	4 to 5 minutes per side

The times apply to a steak of 2 to 3 cm thick in a hot pan. Thicker pieces can be finished in the oven at the end.

Frying eggs

Fried egg

Heat a little butter or oil in a pan over medium-high heat, crack the egg in and let it fry for 2 to 3 minutes until the white is firm. Turn the heat down for a soft white. If you also want the top cooked, put a lid on the pan.

Omelette

Beat two or three eggs with a pinch of salt. Heat butter in a pan and pour in the egg. Pull the edges towards the middle with a spatula, so the liquid egg flows to the edge. When it is almost set, fold the omelette closed.

Cleaning the pan

Let a hot pan cool slightly first and don’t fill it with cold water, because that can warp it. Soak burnt-on food loose with warm water and scrub it with a soft sponge. A stainless steel pan with stubborn residue is cleaned with some water and a splash of vinegar, which you let boil briefly. Wash cast iron only with warm water and a brush, dry it well straight away and rub it with a thin layer of oil.

Frequently asked questions about pan-frying

Why does my meat stick to the pan?

The pan wasn’t hot enough or you turned too early. Wait until the meat comes free by itself.

How do I know the pan is hot enough?

A drop of water sizzles and dances across the bottom immediately. The fat moves easily and the food sizzles on contact.

May I use butter?

Yes, but butter burns quickly. Combine it with oil, or add the butter at the end for flavour.

How often do I turn the meat?

Once or twice is enough. Turning more often gives less crust.

Why does the fat spatter?

There is water on the food. Pat it dry and only use a splatter lid if it doesn’t need to brown.

Remember this

Pan-frying seems simple, but the lesson is big: heat, dry food and space determine the crust. Whoever is patient and leaves the food alone almost always gets a good result.
