Char siu air-fries in about 20 minutes at 380 °F (193 °C), flipped and basted at the halfway point, until the edges are charred and the honey-soy glaze turns sticky and lacquered. Char siu is Cantonese barbecue pork — strips of fatty shoulder or belly steeped in a sweet-savoury marinade of hoisin, honey, soy, Shaoxing wine, and five-spice, then roasted until the outside caramelises into that glossy red-edged crust you see hanging in Chinatown windows. The air fryer's concentrated heat chars the edges fast, so the key is moderate-thickness strips and a baste of reserved marinade at the flip to build the lacquer. Unlike plain Pork Belly, char siu is all about that sweet, five-spice glaze rather than crisp crackling; and unlike Bacon — thin, salt-cured, and crisped flat — char siu stays thick and juicy with a sticky exterior. Use shoulder or belly (the fat keeps it moist at 160 °F), reserve marinade for basting before it touches raw pork, and watch the sugary glaze in the final minutes so it caramelises without burning. Slice it thin across the grain. 4 ways to use it: over rice with greens, in bao buns, chopped into fried rice, or tossed through noodles.

How to tell it’s done

Done when the edges are charred and lacquered, the glaze is sticky and caramelised, and the pork reads about 160 °F (71 °C). Cut strips no thicker than ~1.5 inches so they cook through and char before the sugary marinade burns. Flip and brush on reserved marinade at the halfway mark, then give it a final baste in the last few minutes for that signature deep-red, glossy crust.

Internal temperature: 160 °F / 71 °C. Always verify with an instant-read thermometer.

Step-by-step method

1. 1

   Prep

   Bring ingredients close to room temperature. No oil needed — char siu is fatty pork shoulder or belly and the honey-soy marinade carries plenty of moisture and sheen. The only basting you do is with reserved (uncooked-side) marinade, brushed on at the flip and again near the end to build the lacquer.

2. 2

   Season

   Season with Classic marinade: hoisin, honey (or maltose), soy, Shaoxing wine, five-spice, garlic, and a little red fermented bean curd or red food colour for the signature hue., Marinate at least 4 hours, ideally overnight, for deep flavour and colour., Brush with extra honey in the last 2 minutes for a glossy, sticky finish., Serve sliced over steamed rice with greens, in bao buns, or chopped into fried rice and noodles..

3. 3

   Load

   Arrange lay 2–3 marinated pork strips in a single layer with space between them so the edges char; a 1 lb piece cut into strips serves 2–3 over rice for best convection airflow.

4. 4

   Cook

   Set the air fryer to 380 °F (193 °C) and cook for 20 minutes total, flipping once at 10 minutes.

5. 5

   Check & rest

   Verify the internal temperature reaches 160 °F / 71 °C and rest 2–3 minutes before serving.

6. 6

   Store

   Refrigerate cooked char siu airtight up to 4 days; it slices beautifully cold and reheats well. Warm at 320 °F (160 °C) for 3–4 minutes, or chop into fried rice and noodle dishes. Freezes up to 2 months — slice before freezing for quick use.

Watch out for

• !The marinade is high in sugar and chars fast — keep strips moderate in thickness and watch the last few minutes so the glaze caramelises without turning to bitter char.
• !Reserve some marinade before it touches raw pork for basting; never brush with marinade that pooled under raw meat unless you boil it first.
• !Use shoulder (pork butt) or belly, not lean loin — char siu wants some fat to stay juicy at 160 °F.
• !Cook to about 160 °F for tender, sliceable pork; shoulder stays moist past well-done thanks to its fat.
• !Line or preheat well and flip on time — sticky glaze can weld to the basket if left too long on one side.

FAQ about char siu in an air fryer

What temperature should I cook char siu at in an air fryer?

Cook char siu at 380 °F (193 °C). The convection air at this temperature cooks the centre evenly while still browning the surface.

How long does char siu take in an air fryer?

Char siu takes 20 minutes total at 380 °F (193 °C). Flip the food once at 10 minutes so both sides cook evenly.

Do you need to flip char siu in an air fryer?

Yes — flip char siu once at 10 minutes. The side touching the basket grate develops a darker, more crusted surface; flipping evens out the cook so both sides match.

Do you need to preheat the air fryer for char siu?

Preheating is optional for char siu — most modern air fryers reach temperature in under 2 minutes and the food's total cook time already accounts for the ramp-up. If you do preheat, reduce the total time by 1–2 minutes and check earlier than usual.

What internal temperature is char siu safe to eat?

Char siu should reach an internal temperature of 160 °F (71 °C) measured at the thickest point with an instant-read thermometer. Visual checks alone are not a reliable substitute for protein — always confirm with a probe.
