Ingredients
For the bird
- 1 whole duck, 2–2.7 kg (4.5–6 lb), giblets removed
- 2 tsp fine sea salt
- 1 tsp cracked black pepper
- 1 lemon or orange, halved

- A few sprigs thyme or rosemary
Optional glaze, last 20 minutes
- 2 tbsp honey or maple syrup
- 1 tbsp soy sauce or cider vinegar
- 1 tsp orange zest

Equipment that matters
Roasting tin with a rack
The bird must sit above the fat it releases, or the underside braises instead of roasting.
Instant-read thermometer
Breast and thigh finish at very different temperatures; you need to check both.
Thermometer buying guide
Before you start
Dry the bird, ideally overnight
Pat it dry inside and out, salt the skin, and leave it uncovered on a rack in the fridge overnight. A dry skin is the single biggest factor in a crisp finish.
Prick, do not slash
Prick the fattiest areas — breast sides, thighs, the fat pad at the tail — at an angle with a skewer or sharp knife tip so fat drains without cutting into the meat.
Work out timing and quantity
Use the cooking-time planner for a weight-based range, and the serving calculator if you are buying for a crowd.
Method, step by step
Season and fill the cavity
Salt the skin and cavity, add the citrus halves, garlic and herbs. Do not stuff a duck with stuffing — the cavity contents are aromatics only, and a packed cavity slows the cook badly.
Stage one: render low, breast-side up
Roast at 300–325°F (150–165°C) for roughly 60–90 minutes depending on weight. Fat should collect steadily in the tin.
Watch for Pour off accumulated fat every 30 minutes — a deep pool spits and steams the underside.
Check the legs before browning
Probe the thickest part of the thigh, avoiding bone. Legs should be heading for 175–185°F (79–85°C), where connective tissue has broken down and the meat gives easily.
Stage two: brown hot and fast
Raise the oven to 425–450°F (220–230°C) for 15–25 minutes until the skin is deep mahogany and tight. If you are glazing, brush in the last 10–15 minutes only — sugar burns quickly at this heat.
Watch for Watch continuously in this stage; the gap between burnished and burnt is a few minutes.
Rest properly
Rest 15–20 minutes, loosely tented, before carving. A whole bird carries a lot of heat and the juices need time to redistribute.
Carve breast and legs separately
Remove the legs at the joint, take the breasts off the crown whole, then slice them across the grain. Carving straight down through the bird gives you ragged, uneven slices.
Temperatures and timings
| Part | Target | Why |
|---|---|---|
| Thigh / leg | 175–185°F (79–85°C) | Connective tissue breaks down; meat becomes tender |
| Breast (culinary) | 135–145°F (57–63°C) | Still juicy; commonly served slightly pink |
| USDA recommendation | 165°F (73.9°C) throughout | Food-safety minimum for all poultry |
| Rest | 15–20 minutes | Juice redistribution; carryover of several degrees |
Quack Fix
The four ways this recipe usually goes wrong, what to do about it mid-cook, and how to stop it happening again.
Breast is dry by the time the legs are done
- Likely cause
- The whole roast ran too hot, so the breast overshot while the legs caught up.
- Fix now
- Slice the breast thin and serve with the pan juices or a sharp fruit sauce.
- Prevent next time
- Use the low-then-hot two-stage method, and shield the breast with foil if it runs ahead.
Skin is pale and soft
- Likely cause
- Skin was damp going in, or the high-heat stage was skipped or too short.
- Fix now
- Return the bird to a 450°F (230°C) oven for 10 more minutes, watching closely.
- Prevent next time
- Dry the skin uncovered in the fridge overnight and commit to the hot finish.
Kitchen filled with smoke
- Likely cause
- Fat pooled in the tin and hit the high-heat stage.
- Fix now
- Pour off the fat carefully into a heatproof container and continue.
- Prevent next time
- Drain fat at every check during the low stage.
Use the Whole Duck
Nothing here needs to go in the bin. Each of these is worth more than the packaging suggests.
Rendered fat
Strain and jar it. One whole duck typically yields several hundred millilitres.
Fifteen uses for duck fatCarcass
Simmer with aromatics for a stock far richer than chicken.
Picked meat
Duck hash, fried rice, tacos, or a quick ragù.
Neck and giblets
Brown them and add to the stock pot, or make a small gravy while the bird rests.

Common questions
- How long does a whole duck take to roast?
- Broadly 2–2.5 hours for a 2–2.7 kg (4.5–6 lb) bird using the two-stage method, but weight, oven accuracy and starting temperature all shift it. Use the cooking-time planner for a range and confirm with a thermometer.
- Should I stuff a whole duck?
- No. Stuffing insulates the cavity, extends the cook, and soaks up fat. Use citrus, garlic and herbs as aromatics instead.
- How many people does one duck serve?
- A whole duck usually serves 3–4 as a main because the carcass-to-meat ratio is lower than chicken. The serving calculator accounts for appetite and leftovers.
