AUTHENTIC RECIPE
Purée de Pommes de TerreFrench Potato Purée
A foundational side dish throughout France and one said to reveal a chef’s skill most clearly. Potatoes are boiled whole in their skins to avoid taking on water, sieved while hot, then gradually emulsified with cold butter weighing 25–30% of the potatoes. Unlike Japanese mashed potatoes with added ingredients and seasonings, it is silky smooth and almost sauce-like.

Ingredients (4 servings)
- May Queen potatoesUse a waxy variety such as May Queen that holds its shape. Boil whole, skin-on.800 g
- Unsalted butterCut into 1 cm cubes and keep chilled until needed. Butter weighing 25% of the potatoes is the traditional benchmark.200 g
- Whole milkWarm before adding. Cold milk lowers the purée’s temperature and removes its shine.150 ml
- Salt1 teaspoon for the cooking water and 1/2 teaspoon to finish.1.5 teaspoons
- White pepper0.5 teaspoons
Method
Boil the potatoes whole
- 1 Wash 800 g potatoes thoroughly with skins on and put them whole in a saucepan.
- 2 Add water to cover and 1 teaspoon salt, bring to the boil over high heat, then simmer on low for 25–30 minutes.
- 3 They are cooked when a skewer slides easily to the center.
Tips
Peeling before boiling lets them absorb water and become watery. Whole and skin-on is the traditional method.
Prepare butter and milk
- 1 Cut 200 g butter into 1 cm cubes and refrigerate until needed.
- 2 Warm 150 ml milk in a small saucepan over low heat without boiling; keep it warmer than body temperature.
- 3 MeanwhileDo this while the potatoes boil.
Peel the potatoes
- 1 Drain the cooked potatoes and peel while hot, holding them with a cloth or paper towels.
Caution
Work quickly: cooling firms the starch and prevents proper sieving.
Sieve the potatoes
- 1 While hot, press the peeled potatoes through a fine sieve or potato ricer directly into a saucepan.
Caution
Do not use a food processor or blender. High-speed blades rupture starch cells, creating a gluey texture that ruins the purée.
Emulsify the butter
- 1 Set the saucepan of sieved potatoes over low heat and stir with a wooden spoon for 1–2 minutes to evaporate moisture.
- 2 Add the cold butter in 4–5 batches, allowing each to melt and incorporate completely before adding the next.
Ready when
Continue when all the butter is emulsified and the purée is glossy.
Loosen with milk and season
- 1 Add the 150 ml warm milk in 3 additions, stirring each time to loosen the purée.
- 2 Add 1/2 teaspoon salt and 1/4 teaspoon white pepper, taste and adjust.
Ready when
Ready when glossy on the spoon and slow-flowing as it falls.
About this dish
Potato purée is a foundational accompaniment at every French table, from homes to grand restaurants. In a country full of regional cooking, it is one of the relatively few dishes shared nationwide.
Since potatoes became established on French tables in the late 18th century through the efforts of the pharmacist Parmentier, purée has become an everyday companion to stews and roasts. In homes, it is a familiar part of meat meals, loved across generations.
In the 1980s, chef Joël Robuchon made this rustic side a signature dish, bringing purée onto the world’s gastronomic stage. It remains a culinary-school exercise as a dish that most clearly reveals a chef’s fundamentals.
