Confit Duck Leg
Salt, fat, low heat, time. The four-ingredient miracle of southwest France.
Confit is one of the great preservation tricks turned into one of the great textures. Salt-cure the duck, cook it gently submerged in its own fat at a temperature that never boils, and you end up with meat that pulls clean off the bone, skin that crisps under heat like nothing else, and a sealed jar that keeps for weeks in the fridge. You can buy good confit duck legs in Australia — tinned, vac-packed, deli counters in any decent French-leaning grocer — and there is zero shame in that path. They're the right answer for a weeknight, or for cassoulet day when you've already got pork and beans on the go. But if you've ever wanted to know what a properly cured, slow-fat-poached duck leg tastes like coming out of your own oven, the home method is two days of barely-there work for one of the most generous things you can keep in a fridge.
Confit is salt and fat doing two different jobs at two different stages. The cure pulls water out of the meat and seasons it through. The fat bath then cooks it submerged at a temperature low enough that the muscle fibres never seize — they relax, the collagen melts to gelatin, and the fat seals out air. The crisp at the end is a separate, fast move: dry heat on a fat-coated skin that's been resting in a fridge.
- →Salt cure first, always. The overnight rub draws moisture from the skin and seasons the meat from the outside in. Skip it and the confit tastes flat no matter how long it sits in fat — you cannot season into duck that's already submerged.
- →Below ~90°C the muscle fibres stay relaxed. The fat bath holds the meat at a temperature that gently melts connective tissue into gelatin without squeezing the juices out. A rolling poach would dry the meat and emulsify the fat the wrong way; a bare tremble for three hours gives you the texture you came for.
- →The fat is a seal, not a flavour. Duck fat is mostly inert during the cook — its job is to exclude air, hold even heat, and protect the meat in storage. The flavour is the cured duck itself plus the aromatics in the cure. Reuse the fat two or three times; each round picks up more duck character.
- →Cold confit crisps better than warm. A rested, fridge-cold leg with skin patted dry gives you a crisp under broiler or pan heat that's almost impossible from a leg straight out of the fat. The skin needs to firm up before it can shatter.
- →Storage works because of the seal. A confit leg submerged in its setting fat in a clean jar, fat covering it completely, keeps in the fridge for two to four weeks and tastes better at week two than day one. Break the seal — fat below the meatline, leg exposed — and you've turned a preserve back into leftovers.
Common Mistakes
- ✗Skipping the cure to save a day. You can't. The cure isn't a flavour booster — it's what makes confit confit. An uncured leg cooked in fat is just slow-poached duck, and it tastes like it.
- ✗Cooking the fat too hot. If the fat bubbles hard, the temperature is too high — the meat tightens, the skin goes papery, and the fat picks up a fried flavour instead of staying clean. Aim for 120°C oven, fat surface barely shimmering.
- ✗Lifting the legs out of the fat to store. The fat is the seal. Once cooked, let everything cool together, then refrigerate with the legs fully submerged. Pulled-out legs dry out and oxidise in days.
- ✗Crisping the skin straight from the fat. Wet, fat-slick skin steams before it crisps. Lift the leg out, scrape excess fat back into the jar, and let it sit on a rack in the fridge for at least an hour — ideally overnight — before the crisping move.
- ✗Buying 'duck leg in jus' and calling it confit. They're not the same product. Jus-packed legs are braised and watery; confit legs come packed in solid white fat. Read the label.
Tips & Tricks
- →Going into cassoulet? Skip the final crisping step — the breadcrumb crust crisps the skin from above inside the oven build. Just warm them through and nestle skin-up into the pot for the last 90 minutes.
- →Save every drop of duck fat. Strain through muslin once cooled, store in a clean jar in the fridge. Roast potatoes in it. Fry eggs in it. Sear pork shoulder in it for the cassoulet braise. It's reusable two to three times before the flavour starts to muddy.
- →Aussie sourcing for fresh duck Marylands: Luv-a-Duck and Pepe's Ducks are the two reliable supermarket-level brands. Asian butchers and grocers (especially Cantonese-leaning) often have better whole ducks and Marylands for less than the supermarkets.
- →Aussie sourcing for shop-bought confit: Maison Bruyere, Rougie (imported), or any French deli. Vac-packed lasts months unopened in the pantry — keep a couple in the cupboard for a 30-minute weeknight win.
Flavour Twists
Add the zest of one orange and 2 star anise pods to the cure. Leans the finished duck toward duck à l'orange territory — works beautifully shredded over a bitter-leaf salad with orange segments.
Swap half the sea salt for smoked salt. The smoke note carries through the fat bath and the finished duck reads faintly barbecued.
Drop 10 whole peeled garlic cloves into the fat bath alongside the duck. They confit at the same rate, come out sweet and spreadable, and the fat picks up a deeper garlic note. Mash them on toast with a fork.
Substitutions
- Duck Marylands→ Chicken Marylands (bone-in, skin-on).Chicken confit is a real thing and a great gateway — same cure, same fat-bath, drop oven time to 2 hours. Won't keep as long as duck (3–5 days submerged) because chicken fat doesn't set as solidly, but the technique transfers cleanly.
- Duck fat→ Extra-virgin olive oil (last resort).Olive oil works as a poaching medium but won't give you a proper sealed preserve — eat within 3 days.
- Sea salt flakes for the cure→ Kosher salt by volume, or fine sea salt at ¾ the volume.Don't use iodised table salt — the iodine gives the finished duck a metallic edge after the long cure. Any flaky or coarse non-iodised salt works.
Home-confit legs fully submerged in their setting fat keep 2–4 weeks in the fridge — flavour peaks around week 1–2. Once the seal is broken (a leg lifted out), eat within 3 days. The rendered fat alone keeps 6 months refrigerated and is reusable for the next batch of confit, for searing meats, or for roast potatoes that will ruin all other roast potatoes for you.
Confit is a salt-and-aromatic dish, not a spiced one. The cure carries thyme, bay, garlic and pepper — that's the whole flavour direction. Resist five-spice, juniper, cloves, or anything that pulls it toward sausage or game. The point is a clean, savoury duck flavour that can sit inside cassoulet without arguing with the beans, or on a plate next to fat-roasted potatoes without needing anything else.
Salt. Fat. Low heat. Time. The rest is just patience.
Method
- 1
Path A — shop-bought (30 minutes, start here)
Pre-heat oven to 200°C / 400°F. Lift the confit legs out of their fat (save every scrap in a jar — it's gold for roast potatoes). Scrape the bulk of the fat and jelly off the skin with the back of a knife, then pat the skin properly dry with paper towel. Lay the legs skin-up on a rack over a baking tray. Into the hot oven for 15–20 minutes until the skin is deep golden and crackly, the meat is heated through, and rendered fat is pooling in the tray. Finish with flaky salt on the skin. Serve. Same method warms a confit leg straight into the final stretch of the French Cassoulet build.

Path B, Day 1 — prepare the duck
Rub the duck Marylands all over with the sea salt — over and under the skin, into the joint. Lay them skin-up in a non-reactive dish along with the halved garlic bulbs, ginger coins, thyme, rosemary, cinnamon sticks, bay leaves and crushed peppercorns. Tuck the aromatics around and under the legs so they sit in contact with the meat. Cover and fridge 12–24 hours to enhance the flavour. Don't go longer than 24 — too much cure and the confit reads as cured ham instead of confit duck.

Path B, Day 2 — confit
Pre-heat oven to 120°C / 250°F. Transfer the duck and all the aromatics into a snug oven-safe dish — Dutch oven, deep ceramic, cast-iron casserole — skin-side up, making sure the legs fit without overlapping. Pour off any excess liquid that's pooled in the dish. Pour over melted duck fat until the legs are fully submerged (if the duck fat is solid, melt it first then pour over). Cover tightly with a lid or foil. Into the oven for 3–3½ hours, until the meat is tender and pulls away from the bone easily. The fat should never bubble harder than a lazy shimmer on top — if it's rolling, the oven's too hot, drop it 10°C.

Path B — finish and serve
Carefully lift the legs out of the fat and rest them on a wire rack to drain. For an optional crispy skin texture (worth doing), heat a dry skillet over medium-high and sear the legs skin-side down for 6–8 minutes until the skin is mahogany and shattering — the rendered duck fat on the skin is your oil, no extra needed. Flip 2 minutes flesh-side to warm through. Rest 5 minutes, flaky salt, serve hot alongside roasted vegetables, salad, or mashed potatoes.

Path B — cool and store (if not eating now)
If you're not serving immediately, skip the searing step. Let everything cool in the dish until the fat stops moving, then lift the legs into a clean airtight container and pour the strained warm fat over them until fully covered — every bit of meat below the fat line. Cool to room temp uncovered, then fridge. They keep up to a week (and taste better at day 3–4); the drained duck fat can be saved separately for roast potatoes that will ruin all other roast potatoes for you.
