Classic Cantonese char siu pork prepared either traditionally by roasting and glazing, or using a modern sous vide method for exceptional tenderness with a lacquered finish.
Cover and refrigerate 8–24 hours, turning occasionally.
Remove pork from marinade and reserve marinade for glazing.
Method 1: Traditional Oven-Roasted Char Siu
Preheat oven to 475°F (245°C).
Line a sheet pan with foil and place a metal rack on top.
Arrange pork on the rack with space between pieces.
Pour 1½ cups water into the pan below the rack.
Roast pork for 10 minutes at 475°F, then reduce oven temperature to 375°F (190°C).
Continue roasting for 15 minutes.
Flip pork, rotate pan 180°, and add another cup of water if the pan is dry.
Roast an additional 15 minutes.
Meanwhile, combine reserved marinade with maltose (or honey) and hot water, heating gently until smooth.
After 40 minutes total roasting, begin basting pork with glaze.
Continue roasting and basting every 5–10 minutes until deeply caramelized, 50–60 minutes total.
If needed, briefly broil for color — watch closely.
Rest pork 10–15 minutes, then slice across the grain.
Method 2: Sous Vide Char Siu (Passport Kitchen Method)
Transfer marinated pork to a vacuum-seal bag, using only a light coating of marinade.
Sous vide at 144°F (62°C) for 2–3 hours.
Remove pork from bag, pat completely dry, and air-dry 10–15 minutes.
Prepare glaze by heating reserved marinade with maltose (or honey) and hot water until smooth.
Preheat oven to 425°F (220°C).
Brush pork lightly with glaze and roast for 8–10 minutes, turning once.
Remove pork and rest 15 minutes.
Brush with glaze again, then roast at 375°F (190°C) for 8–10 minutes until glossy and lacquered.
Rest briefly, then slice across the grain.
Notes
Chef NotesPork shoulder provides the ideal fat balance for char siu.Sugar-heavy marinades should never be fully cooked in the sous vide bag.Maltose produces the most traditional lacquer; honey browns faster.Sous vide yields exceptional tenderness but requires aggressive finishing for proper char siu texture.StorageRefrigerate cooked char siu for up to 4 days.Reheat gently or slice cold for rice, noodles, or buns.Char siu freezes well when wrapped tightly.
