How to Make Char Siu

Char siu is Cantonese barbecued pork, marinated in a sweet and savory mixture of hoisin, soy, and honey, then roasted until sticky and charred at the edges. You make it by marinating pork shoulder strips for several hours, roasting on a rack, then finishing with a high heat honey baste that creates the characteristic caramelized crust.

It originates from Guangdong province in southern China and is a fixture of Cantonese barbecue shops, typically seen hanging in restaurant windows alongside roast duck. The name literally translates to fork roasted, referring to the traditional method of skewering the meat vertically to roast over an open flame.

It's the pork you see in char siu bao, fried rice, and noodle soups across Cantonese cooking, and it holds up well made in a home oven with a few adjustments.

What Actually Matters

The final high heat honey baste at the end of roasting is what creates the sticky, charred edges that define char siu. Skip that step and just roast it through at a moderate temperature, and you get pork that tastes like a decent marinade but none of the actual lacquered char that makes the dish recognizable.

The Recipe

Serves 4. Prep time: 15 minutes (plus 4 hours marinating). Cook time: 35 minutes. Total time: 50 minutes active.

Method

  1. Combine the marinade ingredients, reserving the extra tablespoon of honey for basting.

Tips, Variations, and Storage

Pork shoulder gives the best balance of fat and tenderness, though pork tenderloin works for a leaner version with less roasting time. It keeps refrigerated for up to four days, and sliced char siu freezes well for up to two months. Reheat gently to avoid drying it out.

Frequently Asked Questions

Do I need the red fermented bean curd?

No, it's mainly for color and a small flavor boost. The dish tastes very close to authentic without it.

Can I use a different cut of pork?

Pork shoulder is traditional for its fat content, but pork loin or tenderloin work for a leaner result, just reduce the roasting time slightly.

Why isn't my char siu charred at the edges?

The final high heat basting step likely wasn't hot enough or long enough. That step is what creates the char, not the initial roast.

Can I grill it instead of roasting?

Yes, grilling over indirect heat with a final direct heat sear for the glaze works well and adds smokiness.
