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.
The cure is the foundational step and skipping it produces a noticeably inferior result. The salt cure does several things: it draws moisture from the surface and interior of the meat through osmosis, then — given enough time — the moisture is drawn back in carrying the salt and dissolved aromatics (juniper, thyme, pepper) into the muscle fibres. This dry-brining seasons the meat from the inside rather than only the surface. It also changes the protein structure slightly, producing the firmer, more defined texture characteristic of true confit rather than the softer texture of simply slow-cooked duck. Twelve hours is the minimum; 24 hours produces a clearly better result.
Yes — the key is using a pot that fits the duck legs snugly, minimising the volume of fat needed. In a pot just large enough to hold the legs in a single layer, most duck legs will be covered with 600 to 800 g of fat. Alternatively, use a Dutch oven or deep oven-safe casserole and top up with olive oil or goose fat to cover. A slow cooker on the 'low' setting for 6 to 8 hours also works well and requires less fat than the stovetop or oven method since the legs sit in their own rendered fat from the beginning. Do not use a large pot — the extra volume requires proportionally more fat.
Submerged under its fat layer in the refrigerator, duck confit keeps for at least 1 week and up to 3 months when fully covered by fat — this is the traditional preservation technique that predates refrigeration. The fat acts as an anaerobic seal, preventing oxygen from reaching the meat and inhibiting spoilage. The flavor actually improves significantly during the first week as the aromatics in the fat continue to infuse the meat. After 3 to 5 days, a confited leg pulled from the fat and crisped is considerably more complex in flavor than one eaten on the day it was made. To freeze: pack the legs in airtight bags and freeze for up to 3 months.
Pommes sarladaises is the traditional accompaniment from Sarlat-la-Canéda in the Dordogne — thin-sliced potatoes layered and fried in duck confit fat with garlic, finished with flat-leaf parsley. The potatoes absorb the flavoured duck fat and develop a golden, slightly crisp exterior. Other traditional accompaniments include Puy lentils with bacon lardons and shallots (which provide earthy contrast), or simply bitter green leaves dressed with a sharp vinaigrette — the acidity of which cuts through the remarkable richness of the duck. Duck confit is also the essential protein in cassoulet, the great bean stew of Toulouse and Carcassonne.

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.
