Cantonese Roast Duck (广式烧鸭)

Overview

Cantonese roast duck is the civilian counterpart to Peking Duck — equally complex in preparation, faster in execution, and defined by a deeply lacquered skin that shatters on the bite and flesh perfumed from within by a spiced marinade sealed inside the cavity. Where Peking Duck is a ceremony, Cantonese roast duck is a meal: displayed hanging in restaurant windows across the Cantonese diaspora, sold by the half or quarter, eaten over rice or noodles. The preparation involves inflating the duck with air to separate skin from flesh (so the fat renders completely), filling the cavity with a mixture of soy sauce, rice wine, sugar, five spice, and star anise, sealing it shut with a metal skewer, then coating the outside with a malt syrup glaze. The duck is then air-dried — traditionally hanging overnight in a cool, ventilated space — before roasting at high heat. The drying stage is everything: it dessicates the skin so that when it enters the oven, it caramelises immediately rather than steaming. The result is that unmistakeable combination of shattering exterior and juicy, spiced, fat-rich interior.

Flavour Context

lacquered, spiced, rich, deeply savoury, subtly sweet

Key Principles

Inflate the duck under the skin to separate skin from fat layer — a bicycle pump or straw works for home cooks

Seal the cavity completely before air-drying — the internal marinade must not escape

Air-dry for a minimum of 4 hours, ideally overnight uncovered in the refrigerator

The malt syrup glaze must be applied to completely dry skin for lacquering to occur

Roast initially at high heat (220°C) to set the glaze, then reduce to 180°C to cook through

Rest for at least 15 minutes before chopping — the internal juices need to redistribute

Pro Tips

RECIPE:

Serves: 4 | Prep: 20 min | Total: 90 min (includes resting)

---

1 whole duck — 1.8–2kg, cleaned, dried thoroughly

20g salt

15g white pepper

10g five-spice powder — star anise, cinnamon, clove, Sichuan pepper, fennel

30ml soy sauce

15ml dark soy sauce

20ml honey

10ml sesame oil

15ml Shaoxing wine

3 tbsp rock sugar

6 cloves garlic — smashed

6 scallions — white parts only, cut into 5cm lengths

3 slices fresh ginger — 5mm thick

---

1. Pat duck dry inside and out with paper towels; combine salt, white pepper, and five-spice powder, then rub thoroughly over the skin and inside the cavity.

2. Combine soy sauce, dark soy sauce, honey, sesame oil, Shaoxing wine, rock sugar, garlic, scallions, and ginger in a small pot; heat gently for 2 minutes to dissolve sugar, then let cool to room temperature.

3. Brush the cooled marinade all over the duck skin (reserve 3 tbsp for basting); place duck breast-side up on a roasting rack over a deep baking pan filled with 2cm water.

4. Roast at 200°C for 60–70 minutes, basting with reserved marinade every 15 minutes, until skin is mahogany-brown and a meat thermometer inserted into the thickest thigh reads 75°C.

5. Remove from oven and rest for 10 minutes; halve the duck along the backbone and serve hot, sliced or whole, with dipping sauce made from pan drippings.

A clean bicycle pump or hand pump inserted under the neck skin and inflated for 30 seconds effectively separates skin from flesh

For the cavity marinade, toast five spice and star anise briefly in a dry pan before blending into the liquid

Suspend the duck on a rack over a tray lined with foil — the collected fat is excellent for stir-frying vegetables

The glaze mixture (malt syrup, red rice vinegar, and a little water) should be heated before application

Chop Cantonese-style: across the bone in 2cm sections, reassembled in the duck shape for presentation

The remaining carcass makes an exceptional broth for congee — simmer for 2 hours with ginger and spring onion

Common Mistakes

Skipping the air-drying step — the skin steams rather than caramelises and will not lacquer

Not sealing the cavity properly — the internal marinade drains out during roasting

Using honey instead of malt syrup — the flavour profile and texture are different

Chopping immediately after roasting — the juices run and the skin loses crispness from steam

Not basting with the drippings during roasting — the glaze can dry out and burn

Using a duck that hasn't been hung to fully drain of blood — residual moisture prevents lacquering
