Peking Duck with Bao: A Home Roast Recipe

Peking duck is a Beijing-style roast duck known for crisp skin, tender meat, and savory-sweet accompaniments; this home version serves it in soft folded bao with hoisin, cucumber, and scallions. The overnight air-dry helps the skin crisp in the oven, while ready-to-steam buns make the meal manageable without special equipment.

Ingredients

1 whole duck, 5–5½ lb (2.3–2.5 kg), fully thawed, giblets removed
1 tbsp kosher salt (15 g; use 2 tsp fine salt, about 10 g, if needed)
2 tsp Chinese five-spice powder (about 5 g)
2 tbsp maltose (40 g), or 2 tbsp honey (42 g) as a practical substitute
2 tbsp hot water (30 ml)
1 tbsp rice vinegar (15 ml)
1 piece fresh ginger, about 2 in (5 cm; 30 g), sliced
3 scallions (about 45 g), cut into short lengths
12 frozen folded bao buns (about 600 g), thawed according to package directions if required
½ cup hoisin sauce (120 g)
1 medium cucumber (about 250 g), cut into thin matchsticks
4 scallions (about 60 g), cut into thin strips
1 cup fresh cilantro leaves (about 15 g), optional

Instructions

Prepare the duck. Pat the duck very dry with paper towels; do not rinse it, which can spread raw-poultry droplets around the sink. Remove any loose lumps of fat from the cavity and trim excess skin at the opening. Carefully slide your fingers between the breast skin and meat to loosen the skin without tearing it. Use the tip of a small knife or a skewer to prick the skin in several places, especially over fatty areas, taking care not to pierce the meat. This gives rendered fat a way out and helps the skin crisp.
Season and glaze. Rub the salt inside the cavity and over the skin. Put the ginger, the first 3 scallions, and the five-spice powder inside the cavity. Stir the maltose with the hot water until loosened, then mix in the rice vinegar. If using honey, warm it briefly with the water; it is sweeter and can brown faster than maltose, so watch the duck closely near the end of roasting. Brush a thin, even coat of glaze over the duck skin. Set the duck breast-side up on a wire rack over a rimmed tray.
Air-dry the skin. Refrigerate the duck uncovered on its tray for 12 hours, on the lowest shelf and away from ready-to-eat food. The skin should feel dry and slightly tacky rather than wet. This overnight drying is important: damp skin tends to steam before it browns. If the duck still looks visibly wet after 12 hours, leave it uncovered for another hour or two and allow for the longer total time.
Set up the oven. Take the duck from the refrigerator while the oven heats to 325°F (163°C). Put a roasting rack in a roasting pan and add about 1 cup (240 ml) water to the pan, keeping the water below the rack; it helps limit smoking as fat drips. Place the duck breast-side up on the rack. Tuck the wing tips under the body, and keep the pan away from the oven walls.
Roast gently, then crisp. Roast at 325°F (163°C) for about 2 hours 10 minutes. Check the pan once during roasting and carefully pour off excess fat if it is deep; save it for another use if desired. Raise the oven to 425°F (218°C) and roast about 25 minutes more, until the skin is deeply golden and crisp. If a spot is browning too quickly, loosely cover that area with foil. Check the thickest part of the breast and the inner thigh with a food thermometer without touching bone. USDA FSIS gives duck a safe minimum internal temperature of 165°F (74°C); if either area is below that, continue roasting and check again every 10 minutes. Oven times vary with the bird’s shape and starting temperature, so the thermometer reading, not the clock, determines when it is done.
Rest, warm the bao, and carve. Transfer the duck to a clean carving board and rest it for 20 minutes. While it rests, steam the bao according to the package directions, usually about 8–10 minutes for frozen buns; keep them covered so they stay soft. Carve the breast into thin slices and remove the leg and thigh meat, slicing or pulling it into bite-size pieces. Arrange the crisp skin with the meat, and serve with the warm bao, hoisin, cucumber, scallions, and cilantro.
Assemble at the table. Spread a little hoisin inside a bao, add a few slices of duck with some crisp skin, then top with cucumber, scallion, and cilantro. Fold the bun around the filling and eat while warm. Add the sauce sparingly at first; too much can overwhelm the duck and make the bun messy.

Tips

Plan for a fully thawed bird. A frozen duck may need a day or two to thaw safely in the refrigerator, depending on its size. Keep it contained on a tray and begin the 12-hour uncovered drying only once it is thawed and patted dry.
Keep the skin intact. Loosen it gently and prick only the skin, not the flesh. Tears let juices escape and can make the breast dry before the skin is crisp. If you accidentally pierce the meat, simply continue carefully and monitor the temperature.
Use honey if maltose is hard to find. Maltose is a traditional, thick syrup that gives the glaze a gentle shine and less pronounced sweetness. Honey is an easy grocery-store alternative, but its flavor is more noticeable and it can darken sooner, so check the skin during the high-heat finish.
Choose the right bun. Frozen folded gua bao are convenient and hold the filling well. If you can only find plain steamed buns, split them and use them like small sandwiches; the flavor is similar, though they will not fold around the duck in the same way.

Serving Suggestions

Set out the carved duck and accompaniments separately so everyone can assemble bao to taste. A little hoisin provides the familiar sweet-salty base; cucumber adds a cool crunch, and scallions or cilantro bring a fresh, sharp contrast to the rich duck. Keep extra buns covered in a clean steamer or under a dry towel between batches, and serve the duck as soon as it has rested so the skin stays crisp.

For a fuller meal, add a simple stir-fried green vegetable, such as bok choy or gai lan, and a bowl of steamed rice. These sides are not required—the duck and bao are satisfying on their own—but they make the meal easier to stretch for a group. If serving children or guests who prefer milder flavors, put the hoisin on the side and let them choose their own fillings.

Variations

For a more traditional Peking-duck-style presentation, serve thin wheat pancakes instead of bao. The duck is often wrapped with sauce and crisp vegetables in pancakes; the bao version here is a soft, substantial alternative, not a claim that bao are the only or original accompaniment. Thinly sliced daikon or carrot can join the cucumber, and a small amount of Chinese sweet bean sauce can replace some of the hoisin for a deeper, less sweet flavor.

You can also make the meal easier by buying plain steamed buns and serving them split, or use small tortillas if bao are unavailable. Tortillas are thinner and less fluffy, so they make a different kind of wrap, but the duck, sauce, and crunchy vegetables still work. For a gentler spice profile, omit the five-spice powder from the cavity; for more aromatic warmth, add a few slices of orange peel alongside the ginger. Keep additions modest so they do not crowd the duck’s flavor.

Storage and Reheating

Refrigerate leftover duck within 2 hours of cooking, ideally with the meat and skin stored separately from the buns and vegetables. Keep the duck in a covered, shallow container and use it within 3–4 days. Store unopened or leftover bao according to the package directions; refrigerate steamed buns promptly and use within a few days, or freeze them for longer storage. Keep sliced cucumber and fresh herbs separate, since they soften quickly.

For the best texture, reheat duck pieces on a rack in a 375°F (190°C) oven until hot, then briefly use a hotter oven or broiler to refresh the skin, watching carefully to prevent burning. Reheat leftovers to 165°F (74°C), as measured with a food thermometer. A microwave is convenient for the meat but softens the skin; if using one, heat in short bursts and crisp the skin separately in a hot skillet or oven. Steam bao until hot and pliable. Do not leave cooked duck or steamed buns at room temperature for more than 2 hours.

Frequently Asked Questions

Can I make the duck without drying it overnight?
Yes, but the skin is less likely to turn crisp. If time is short, dry the duck thoroughly with paper towels and refrigerate it uncovered for as long as possible, preferably at least 4 hours. The recipe’s 12-hour drying time gives moisture more time to evaporate; it is a quality step, not a reason to leave raw poultry out at room temperature.

Do I need to flip the duck while it roasts?
No. Keeping it breast-side up through the roast makes the process simpler and protects the skin you have dried. The rack lets hot air circulate underneath, while the final high-temperature stage browns the outside. If your oven heats unevenly, rotate the pan once, using oven mitts and keeping it level so hot fat does not spill.

Why is there so much fat in the roasting pan?
Duck naturally has a substantial layer of fat beneath the skin, and some renders during roasting. That is expected. Carefully drain excess fat if it is close to the rack or smoking, and avoid pouring it down the sink. If saving it, strain it into a clean container, cool it promptly, and refrigerate it; use it within a few days.

Can I roast the duck a day ahead?
You can roast and carve it ahead, then refrigerate the meat and skin promptly in separate covered containers. Reheat the duck to 165°F (74°C), then use a hot oven to crisp the skin as much as possible. It will not be quite as crisp as freshly roasted duck, so if serving for a special meal, the best result comes from roasting close to serving time.

What if my duck reaches 165°F before the skin is crisp?
Take its temperature in both the thickest breast area and the inner thigh, avoiding bone. Once the required temperature is reached, protect the meat from overcooking: use a brief broiler finish or a hot skillet for the skin, watching continuously. A broiler can brown the glaze very quickly, especially if you used honey, so do not walk away.
