This is the dish that reveals everything about your pan and your heat. Done right, they're golden outside, tender inside, and there are never any left. Done wrong, they're limp, greasy, or welded to the base.
Each of the three failures has a precise cause. Here's the method, and what you need to understand to stop getting it wrong.
Choosing the potato
Use a waxy variety: Charlotte, Ratte, Amandine, Roseval, or anything sold for roasting or sautéing. They hold together and keep their edges.
Floury varieties — those sold for mash or chips — fall apart. They make excellent chips because they're submerged in oil, but in a pan they crumble when you turn them.
The par-boiling question
Both ways work, and they don't give the same result.
With par-boiling — the safer route
Cut into 2 to 3 cm cubes. Start them in cold salted water, bring to the boil, then count 7 to 8 minutes from the simmer. A knife tip should go in with slight resistance: they must not be cooked through, only nearly.
Drain, and let them dry for ten minutes in the colander, in the air. That's the step everyone skips and the one that decides: a wet potato doesn't brown, it steams in its own water.
The tip: shake the colander to rough up the surface slightly. Those rough edges become the crunch.
Without par-boiling — longer, more flavour
Cut smaller, 1.5 to 2 cm. Allow 20 to 25 minutes on medium heat, stirring rarely. It takes patience and a lid for the first ten minutes, then you finish uncovered on medium-high to brown.
The flavour is cleaner, because nothing has been leached out into cooking water.
And for a grated potato cake rather than cubes: Swiss rösti in a pan.
The cook, step by step
- Wide pan, empty, medium-high heat, 2 to 3 minutes. Use the water drop test.
- Add the fat: two to three tablespoons. Neutral oil or olive oil, or better, oil plus duck fat (the fat from a duck breast, kept in the fridge). Butter alone would burn — it comes at the end.
- Tip the potatoes in, in a single layer. They must not overlap. If they don't fit, do two batches: it's the most important rule in the recipe.
- Don't touch them for 3 to 4 minutes. Each face needs to stay still to brown. Stirring every thirty seconds is the surest way to get pale, sticky potatoes.
- Turn them, and repeat. Three or four times, to brown several faces. Allow 12 to 15 minutes in total after par-boiling.
- In the last minute: a knob of butter, two crushed unpeeled garlic cloves, thyme or rosemary. Shake the pan for 60 seconds.
- Salt at the end, off the heat. Salt added too early draws water out and blocks the crunch.
The three failures, and their exact cause
They're limp
Too much moisture. Either they didn't dry after par-boiling, or the pan was overloaded and the water from all the potatoes pooled in the base. Either way, they steamed.
They're greasy
The pan wasn't hot enough when they went in. A hot surface sears and seals; a lukewarm one lets the fat soak in.
They stick to the base
Same cause, plus a second: they were stirred too early. Starch grips the metal for the first few minutes, then releases by itself once the crust has formed. Scrape with a spatula before that and you tear off the golden face and leave it in the pan.
If golden bits stay stuck anyway, nothing is lost: a splash of hot water and thirty seconds with a wooden spoon lifts them — the four methods.
Which pan
The widest your burner can heat properly: surface area is what decides, and surface area sets the number of batches. For 800 g of potatoes you want a 28 cm; a 24 cm handles 500 g comfortably — which size to choose.
And you have to be able to get the heat up. That's why this dish fails so often in a tired non-stick: you turn the heat down to protect the coating, and on low heat a potato never browns.
The pan we film with is 304 stainless with no coating, with the 25-recipe book (in French) free.
Pick the right size for your potatoes
For 500 g, the 24 cm cooks them comfortably in a single layer. For 800 g, go for the 28 cm. The 22 cm suits small batches. Each link adds the pan and the free book to your cart, no code needed:
