The basics
Frying potatoes in a pan is about heat and patience. The potato needs to be cooked through and have a crisp brown surface, and the pan doesn't give you much time. Most of the methods here cook the potato first, then brown it.
| Dish | Potato | Cook first? | Heat | Key trick |
|---|---|---|---|---|
| Sauté potatoes | Waxy or all-rounder cubes | Par-boil 5 minutes | Medium-high | Dry, single layer, leave alone |
| Hash browns | Grated floury | No | Medium | Squeeze dry |
| Rösti | Grated floury | Optional | Medium | Press, and don't touch |
| Tortilla | Thin sliced waxy | Cooked gently in oil | Medium-low then medium | Don't brown; flip with a plate |
- A dry potato fries; a wet one steams. Dry or squeeze everything.
- Don't crowd the pan. A single layer, with gaps, or in batches.
- Leave it alone until the base is golden. Moving potatoes too early tears the crust.
- A good non-stick pan is worth it for rösti and tortilla.

Sauté potatoes
Parboiling cooks the potato through, so the pan only has to brown the outside. It's the reliable way to get crisp edges with a soft middle.
Ingredients (2 portions)
- 400 g waxy or all-rounder potatoes, cut into 2 cm cubes
- 1 tsp salt, for the water
- 2 tbsp sunflower or olive oil
- 10 g butter
- 1 garlic clove, crushed
- 1 tbsp chopped parsley
- 1 pinch flaky salt
- Cover the potatoes with cold salted water, bring to the boil and simmer for 5 to 6 minutes, until barely tender. Drain and dry thoroughly.
- Heat the oil in a large non-stick or heavy frying pan over a medium-high heat. Add the potatoes in a single layer, and leave them alone for 4 to 5 minutes, until golden underneath.
- Turn and cook for another 8 to 10 minutes, turning occasionally, until golden all over.
- Add the butter and garlic for the last minute, then the parsley and flaky salt.
Level 2 · Breakfast
Hash browns
Grated potato is mostly water and starch. Squeeze it dry and rinse away the surface starch for the crispest results.
Ingredients (2 portions)
- 250 g floury potatoes, peeled
- ½ small onion, grated (optional)
- 1 tbsp plain flour
- 1 pinch salt and pepper
- 2 tbsp sunflower oil
- Grate the potato on the coarse side of a grater. Rinse in a bowl of cold water, drain, and squeeze as dry as you can in a clean tea towel.
- Mix the potato with the onion, flour and seasoning. Shape into 4 flat patties about 1 cm thick.
- Heat the oil in a frying pan over a medium heat. Fry the patties for 5 to 6 minutes a side, pressing lightly, until deep golden (not dark brown) and cooked through.
- Drain on kitchen paper and serve straight away.
Go for gold
Grated potato browns fast. Keep the heat medium and aim for golden.
Level 2 · Swiss
Rösti
Rösti is grated potato cooked as a single cake in a pan. Use a non-stick pan, medium heat, patience, and no peeking.
Ingredients (2 portions)
- 300 g floury or all-rounder potatoes, peeled
- ½ tsp salt
- 2 tbsp sunflower oil
- 10 g butter
- Grate the potatoes coarsely. Squeeze dry in a tea towel and mix with the salt.
- Heat the oil and butter in a 20 cm non-stick pan over a medium heat. Add the potato, spread evenly and press down firmly.
- Cook for 10 to 12 minutes without moving it, until the base is deep golden. Slide it onto a plate, invert the pan over the plate and flip the rösti back in (use oven gloves).
- Cook the other side for another 8 to 10 minutes. The middle should be tender when pierced.
Par-boiled version
Par-boil the whole potatoes for 5 minutes, cool, then grate. The rösti is softer inside and cooks faster.
Level 3 · Spanish
Spanish potato tortilla
A Spanish tortilla has potatoes softened in oil (not browned), then bound with egg and cooked into a thick omelette. This version is cooked until set all the way through.
Ingredients (3 portions)
- 400 g waxy or all-rounder potatoes, peeled and thinly sliced (3 mm)
- 1 onion, thinly sliced
- 100 ml olive oil
- 5 Lion-marked eggs
- 1 pinch salt and pepper
- Heat the oil in a 24 cm non-stick pan over a medium-low heat. Add the potatoes and onion with a pinch of salt and cook gently for 15 to 20 minutes, turning often, until tender but not browned.
- Beat the eggs in a large bowl with salt and pepper. Strain the potatoes and onion in a sieve over a bowl (keep the oil), and fold them into the eggs. Leave for 5 minutes.
- Return 1 tablespoon of oil to the pan over a medium heat. Pour in the mixture and cook for 5 to 6 minutes, shaking the pan, until the base is set and golden.
- Put a large plate over the pan, flip the pan over (use oven gloves, over the sink), then slide the tortilla back in, uncooked side down. Cook for 4 to 5 minutes more, until set all the way through.
- Rest for 5 minutes, then cut into wedges. Serve warm or at room temperature.
Cooked through
Traditional tortilla is left runny in the middle. Lion-marked eggs are safe to eat lightly cooked, but this recipe is cooked until set. If you serve it for anyone in a higher-risk group, keep it firm.
Experiments
Experiment
Parboiled or raw
Do you need the first cook?
- Fry cubes of raw potato and parboiled potato in two pans, the same oil and heat.
- Cook until each is done.
Look for: The raw potatoes take much longer and are often dark outside before they are done in the middle. The parboiled ones are crisp and tender.
Experiment
Oil, butter or both
Which fat?
- Fry three batches of sauté potatoes: in oil, in butter, and in oil with butter added at the end.
- Taste each.
Look for: Butter alone burns and goes dark. Oil browns well. Oil with butter at the end gives the best flavour.
Experiment
Pan size and heat
Crowded or spacious?
- Fry the same potatoes in a small pan (crowded) and a large pan (single layer).
- Compare the browning.
Look for: The crowded potatoes steam and stay pale. The single layer browns.
Experiment
Pressed or turned
Do you touch the rösti?
- Cook two röstis. Press one down and leave it for 10 minutes. Stir and turn the other every minute.
- Compare how they hold together.
Look for: The pressed one forms a cake with a crisp crust; the stirred one falls into crispy strands (hash-style).

Troubleshooting
| Problem | Likely cause | What to do |
|---|---|---|
| Pale and soggy | Wet, crowded, or heat too low | Dry thoroughly; one layer; medium-high heat |
| Burnt outside, raw inside | Too hot, or skipped the cook first | Parboil; lower the heat |
| Sticking | Pan not hot, or moved too soon | Heat the pan and oil; wait until it releases |
| Rösti falls apart | Too wet, or turned too early | Squeeze dry; press; leave 10 minutes |
| Tortilla stuck to the pan | Poor non-stick, or not enough oil | Use a non-stick pan and add oil |
| Greasy | Oil not hot enough | Heat the pan first; drain on kitchen paper |
Food safety: frying, eggs and acrylamide
Go for gold. When starchy foods such as potatoes are fried, roasted or baked at high temperatures they form a chemical called acrylamide, which the Food Standards Agency says could raise cancer risk. Its advice is to cook to a golden yellow, not dark brown, and to follow the packet instructions on bought chips and roasties. A balanced diet matters more than any single food, so this is a nudge about colour, not a reason to avoid potatoes.Hot oil in a pan can spit. Dry the potatoes, use a pan with sides, and never leave it. The tortilla contains eggs, so use Lion-marked eggs and cook it until set. Raw potatoes: keep them somewhere cool, dark and dry (above about 6°C), not in the fridge and not in the light. The Food Standards Agency advises against keeping raw potatoes in the fridge if you will roast or fry them, because the cold raises the amount of acrylamide that forms when they brown. Light turns the skin green and makes sprouts, and the green and the sprouts contain a natural toxin (solanine) that is bitter and can upset your stomach. Cut away sprouts and any green patches generously; if a potato is green all over, or tastes bitter, throw it away. Cooking does not remove it.
Cooked potatoes: cool them quickly (spread out, within 1 to 2 hours), keep them covered in the fridge, and eat them within 2 days. Reheat until steaming hot all the way through, and only once. (This is the general chilled-leftovers advice relayed by local-authority food-safety pages; unlike rice, potatoes have no special rule of their own, but they are starchy, so they are treated with the same care.)
Checkpoint: can you do this now?
- I can parboil, dry and brown potatoes in a pan.
- I can squeeze grated potato dry.
- I can make rösti and flip it safely.
- I can make a tortilla set all the way through.
- I know to leave potatoes alone until golden.
