Chestnut velouté recipe: Michel Roux Jr's autumn starter

This chestnut velouté recipe is the Cévennes' own, the one Michel Roux Jr serves to open a meal: velouté de châtaignes, built on chestnuts roasted hard enough to split their shells, then simmered low and pushed through a sieve for a texture no blender alone gives.

The dish comes from the chestnut forests of the Cévennes, where terraced groves have fed whole valleys since Roman times. Roux Jr, who ran Le Gavroche's kitchen for three decades and still cooks this year aboard Cunard's Le Gavroche at Sea residencies, published a version in his cookbook The French Kitchen, built on dried chestnuts soaked overnight; October brings fresh ones back to French markets, so soaking drops out and a hard roast takes over.

Growers in the neighbouring Ardèche, nursing a lighter crop after this summer's drought, are reason enough to cook this one as soon as it lands.

A proper velouté earns its silk from a sieve, never from extra cream.

Ingredients

• 600 g fresh chestnuts, in their shells
• 20 g unsalted butter
• 1 small onion, finely chopped
• 1 celery stick, finely chopped
• 1 bay leaf
• 2 sprigs thyme
• 800 ml light chicken or vegetable stock
• 1 tart apple (such as Reinette), plus a few matchsticks to garnish
• 100 ml double cream
• 1 tsp walnut oil, to finish
• Salt and freshly ground white pepper

Method

1. Score each shell with a cross and roast the chestnuts at 220°C for 15-18 minutes, until they split; the heat caramelises the sugars slightly and loosens the skin for peeling.
2. Peel while still warm, shell and inner skin together; a stubborn one goes back under a tea towel for a minute, since the trapped steam finishes the job.
3. Sweat the onion and celery in the butter over low heat for 5 minutes until soft but not coloured, so the base stays sweet rather than competing with the chestnut.
4. Add the chestnuts, bay leaf, thyme and stock, and simmer gently for 25 minutes, until a chestnut crumbles under a spoon; slow heat breaks down the starch without reducing the stock too hard.
5. Peel, core and chop the apple, stirring half of it in for the final 5 minutes, just enough to soften without tipping the soup toward sweet.
6. Discard the bay and thyme, blend until smooth, then pass through a fine sieve; the sieve is what makes a velouté velvety rather than just a chestnut soup.
7. Return to low heat, whisk in the cream gradually, season, then ladle into warm bowls topped with raw apple matchsticks and a thread of walnut oil to cut the sweetness.

The AOP pedigree behind this chestnut velouté recipe

The Châtaigne des Cévennes earned AOP status in 2023, the first time France protected a chestnut variety by name as it already does for certain cheeses and wines. Out of season, a jar of whole cooked chestnuts is the one acceptable shortcut for this chestnut velouté recipe: vacuum-packed, they need no more than 15 minutes in the stock before blending.

Serve in small cups rather than bowls if this opens a longer menu, and pour a dry Loire Chenin Blanc or a brut Normandy cider alongside; both carry enough acidity to cut the sweetness.

Can this chestnut velouté recipe be made a day ahead? Yes, up to the sieving stage; keep it covered in the fridge and stir in the cream only after reheating gently, so it doesn't split.
