Duck Confit (Confit de Canard)
Confit de canard is the defining dish of Gascony, the south-west corner of France where ducks are raised for foie gras and the region's most celebrated cooking technique is confit — from confire, to preserve. Duck legs are cured overnight in salt, pepper, thyme, and juniper, then submerged in duck fat and cooked at a barely trembling 100°C (210°F) for two and a half hours until the meat becomes impossibly tender and slides from the bone. The result is stored under its fat blanket in the refrigerator — the traditional method of preservation before refrigeration — where it continues to develop flavor over days or weeks. To serve, the legs are pulled from the fat and placed skin-side-down in a cold pan, then brought to high heat until the skin crackles and blisters to a dark, shattering gold. The interior stays fall-apart tender. The reserved duck fat is one of the finest cooking fats in the world — use it to fry potatoes.
Ingredients
- 4 duck legs
- 3 tbspcoarse sea salt
- 1 tspblack peppercorns, coarsely crushed
- 1 tspjuniper berries, coarsely crushed
- 6 sprigs of fresh thyme
- 3 bay leaves
- 4 garlic cloves, unpeeled and lightly crushed
- 800 gduck fat
- 1 tbspfine sea salt
- 6 black peppercorns
Method
- Cure the duck overnight. Mix the coarse sea salt, crushed peppercorns, crushed juniper berries, thyme, and bay leaves in a bowl. Rub this mixture all over the duck legs on every surface — skin side, flesh side, around the bone — coating generously. Pack the legs in a snug dish or zip-lock bag, add the crushed garlic, cover, and refrigerate for 12 to 24 hours. The salt draws moisture from the meat and begins to season it deeply. The juniper gives Gascon character.
- Rinse, dry, and prepare the fat. Remove the duck legs from the cure. Rinse thoroughly under cold running water to remove all the salt, spices, and herbs — any salt left on the surface during cooking will make the confit too salty. Pat completely and aggressively dry with paper towels. Moisture in the fat causes sputtering. Leave to air-dry for 30 minutes if possible. Meanwhile, melt the duck fat gently in a deep, snug-fitting pot or Dutch oven — the pot should be just large enough to hold the legs in a single layer with the fat covering them. Add 1 tbsp fine salt and the peppercorns to the fat.
- Cook low and slow. Place the duck legs skin-side-down in the cold fat, then bring slowly to a very gentle simmer — the fat temperature should read 80 to 100°C (175 to 210°F) and never exceed it. At the correct temperature, only a few small bubbles rise around the legs; the fat should not fry or sizzle. Transfer to an oven preheated to 120°C (250°F) if you are unsure about maintaining stovetop temperature. Cook for 2 to 2.5 hours until the meat has shrunk visibly from the bone, feels very soft when gently pressed, and a skewer passes into the thickest part with no resistance.
- Store under fat (optional but recommended). Remove the legs carefully from the fat and set aside. Strain the fat through a fine sieve to remove any solids. Pack the duck legs into a clean container, pour the strained fat over them until completely submerged, cool to room temperature, and refrigerate. Stored this way, duck confit keeps for 1 week (refrigerated) or up to 3 months. The flavor improves dramatically after 3 to 5 days as the meat mellows and the fat infuses through it. This is the traditional preservation method from Gascony.
- Crisp the skin before serving. Remove the legs from the fat (scrape off excess). Place skin-side-down in a cold, dry, heavy pan — cast iron is ideal. Set over medium heat and cook undisturbed for 6 to 8 minutes as the skin renders its own fat and gradually crisps. Do not touch, press, or move the legs — patience produces the shattering crackle. When the skin is dark amber and crackling, turn briefly for 1 minute to heat the flesh side. Serve immediately: duck confit does not hold well after crisping. Classic accompaniments: sarladaise potatoes (fried in the confit duck fat with garlic and parsley), Puy lentils with shallots, or a bitter green salad to cut the richness.
FAQ
Confit is a preservation technique in which food is slow-cooked in its own fat at a low temperature. For duck, the legs are submerged in rendered duck fat and held at 80 to 100°C (175 to 210°F) — well below the boiling point of water — for 2 to 2.5 hours. At this gentle temperature, the tough collagen in the duck's leg muscles (which are heavily worked, load-bearing muscles full of connective tissue) converts slowly to gelatin, producing the characteristic silky, unctuous, fall-off-the-bone tenderness. The fat acts as a temperature-stable medium that heats the meat gently and evenly from all sides simultaneously. The same result cannot be achieved by roasting or braising — only the low, even heat of fat at the right temperature produces this specific texture.

Traditional duck confit takes 36 hours if you count the salt cure, but the result is unlike anything else you can make at home. The salt draws out moisture overnight, then you slow-cook the legs submerged in their own fat at a temperature so low the meat falls off the bone. The final step — crisping the skin in a hot pan — is the moment of truth. Skin-side down, do not move it, 4 minutes until it crackles. I save the rendered duck fat and use it to roast potatoes for weeks afterward. Nothing on earth makes better roast potatoes.
