Walking past a Chinese BBQ shop and seeing rows of Chinese roast duck hanging in the window is irresistible. This straightforward recipe yields beautifully browned, crispy skin with tender, juicy meat underneath. The real trick is air-drying the duck in the refrigerator for 24–72 hours to remove surface moisture and allow the skin to crisp perfectly.

🦆 About This Recipe
Growing up, weekend trips to Chinatown meant sharing half a roast duck and a box of crispy pork belly with my family. The duck’s skin—crisp, deeply browned, and not overly fatty—was always my favorite. After eating it for years, I decided to recreate that texture at home.
My first try failed: I roasted the bird without prepping the skin and got little color or crunch because the skin stayed too moist. On my second attempt I followed what Chinese roast houses do—air-dry the duck for a day or two. Since I couldn’t hang it outside, I placed it in the refrigerator.
I dried the duck for 48 hours, rotating it periodically to ensure even drying. The result was a much crisper, brown skin and significantly less fat under the skin. Some areas near the sides retained a bit of fat, but overall it was exactly what I wanted.
🍗 How to Get Crispy Skin
The most important step is drying the duck for at least 24 hours and up to 72 hours. Skipping this will usually prevent the skin from developing the right color and crunch.
To dry the duck: place it on a wire rack over a tray in the fridge to catch drips. Rotate the bird every 8–12 hours so all sides dry evenly. A colder spot in the back of the fridge works best. Proper drying removes surface moisture so the skin can get hot enough in the oven to render fat and crisp up.
🧂 Ingredients
- Whole duck: about 5–6 lbs. If frozen, defrost in its packaging in the fridge for 24 hours before starting.
- Aromatics: ginger, scallions, star anise, and a cinnamon stick—stuffed in the cavity to infuse flavor.
- Marinade: hoisin sauce, soy sauce, brown sugar, and Chinese five-spice powder—rubbed into the cavity.
- Glaze: maltose (or honey), rice wine vinegar, salt, and water—brushed on before roasting to promote a glossy, crisp skin.
🔪 Instructions
STEP 1: Prepare a roasting pan by lining it with foil. Add ½ inch of water or 2 cups of coarse salt to the bottom to catch fat drips and prevent smoking. Salt is preferred to avoid steam that can soften the skin.
STEP 2: Rinse the duck under cold water. Trim the neck and excess fat around the cavity. Pat the duck thoroughly dry inside and out with paper towels and place it on a roasting rack, breast side up.
STEP 3: Mix hoisin, soy, brown sugar, and five-spice in a small bowl. Rub the mixture inside the cavity and all over the inner surfaces. Stuff ginger, scallions, star anise, and cinnamon into the cavity, then close the openings with a bamboo skewer.
STEP 4: Transfer the pan and duck to the refrigerator and dry for 24–72 hours, rotating every 8–12 hours for even airflow. When ready to roast, let the duck sit at room temperature for about one hour.
STEP 5: Combine maltose (or honey), salt, rice wine vinegar, and water. Brush the glaze over the entire duck, front and back, making sure to coat crevices like between the wings and breast.
STEP 6: Roast at 400°F on the upper-middle rack for 40 minutes, until the skin turns golden brown. After the first 15 minutes, tent the wings with foil to prevent over-browning.
STEP 7: Lower the oven to 350°F, carefully flip the duck using oven mitts and folded paper towels for a good grip, and roast another 40–50 minutes. The thigh should read about 160°F and the breast about 145°F when done. Remove and rest for 15 minutes before carving.
