French recipe: duck Parmentier

Chef Matthew Ryle's mouth-watering French classic elevates shepherd’s pie with confit duck legs, perfect for warming up in cold weather

For this duck Parmentier you can use shop-bought confit de canard or make your own

I only came across this dish recently: a more interesting, delicious version of shepherd’s pie. A real hearty dish that I keep for cold weather.

Rather than minced meat, duck legs are cooked whole, gently, in their own fat until the meat falls off the bone. 

To make this easy, buy your duck legs ready confited: you can find them in good supermarkets. Simply warm the legs in their fat, then flake the meat from the bones. I challenge anyone to tell the difference.

Prep time 

20 minutes, plus 6 hours optional salting

Cooking time 

1½-3½ hours

Serves 4

*You will need a piping bag.

Method

1. If making the confit, do it the day before making the Parmentier. Sprinkle a baking tray with half each of the rock salt, thyme and garlic. Put the legs on top, skin side up. Sprinkle with the remaining aromats and leave to cure for 6 hours.

2. Preheat the oven to 120°C fan (275°F). Wash the aromats off the duck and dry with kitchen paper. Melt the duck fat in a deep ovenproof pan, add the duck and place in the oven for 2½-3 hours. The meat should be easily coming away from the bones. Leave to cool slightly before removing the skin and shredding the meat. If you have gone for shop-bought confit duck legs, gently warm them in their fat so you can easily remove the skin and shred the meat.

3. Preheat the oven to 180°C fan (400°F). Prick the potatoes with a sharp knife, place them in the oven in a baking tray on a bed of rock salt and bake for 1 hour.

4. Put the 50g (3tbsp) of duck fat for the filling in a saucepan over a medium heat and sweat the onions for 5–10 minutes until very soft, but without color. Add the garlic and cook for another 5 minutes. Add the shredded duck, stock, herbs and seasoning. Pick an ovenproof serving dish and pour in the duck mix.

5. Increase the oven temperature to 220°C fan (475°F).

6. Scoop out the cooked potato flesh and put it through a sieve or ricer. Add the butter, milk and egg yolk, mix well, check the seasoning and place in a piping bag. Pipe the potato on top of the duck mix and bake for 20 minutes until golden brown and crisp.
