The char siu is the star here. Asian markets sell it pre-made, or buy pork shoulder and roast it yourself with hoisin, five-spice, and honey for that signature sweet-savory flavor. For the dough, King Arthur Flour is my go-to—consistent quality every time. Yeast freshness is critical; if it doesn’t bubble in warm water within 5 minutes, start over (don’t risk flat buns).

No hoisin? Substitute with extra oyster sauce plus a splash of honey. Out of oyster sauce? Soy sauce with a pinch of brown sugar works in a pinch. Green onions can be swapped for chives, though the flavor will be milder. The cornstarch thickens the glaze—arrowroot powder is an equal swap if that’s what you have.

Dough can be refrigerated overnight if needed—just bring to room temp before shaping. Steamed buns keep in the fridge for 3 days or freeze for 1 month. Reheat by steaming again for 5 minutes (microwaving makes them rubbery).

Step-by-Step Instructions for Chinese BBQ Pork Buns

Master the art of these steamed buns with a soft, fluffy texture and rich char siu filling.

Step 1: Prepare the Filling

Finely dice the 1.5 lb Char Siu (Chinese BBQ Pork) into small, even pieces. In a bowl, combine the diced pork with 3 tbsp Hoisin Sauce, 2 tbsp Oyster Sauce, 2 tbsp Light Soy Sauce, 1 tsp Sesame Oil, 2 cloves minced Garlic Cloves, and half of the 0.5 tsp Salt.

Mix well until the pork is evenly coated with the sauce. In a small bowl, dissolve 1 tbsp Cornstarch in 2 tbsp of water to make a slurry, then stir it into the pork mixture. This helps thicken the filling and keeps it moist during steaming.

Step 2: Make the Dough

In a large bowl, combine 3 cups All-Purpose Flour, 1 tsp Active Dry Yeast, the remaining 0.5 tsp Salt, 1 tsp Baking Powder, and 0.25 cup Granulated Sugar. Mix the dry ingredients thoroughly to ensure even distribution of the yeast and leavening agents.

Create a well in the center of the dry mixture and pour in 1 cup Warm Water and 2 tbsp Vegetable Oil. Use a wooden spoon or your hands to mix until a shaggy dough forms. The water should be 110°F to activate the yeast without killing it.

Step 3: Knead and Rise the Dough

Turn the dough out onto a lightly floured surface and knead for 8-10 minutes until smooth and elastic. The dough should be soft but not sticky—add a little more flour if needed, but avoid over-flouring, as this can make the buns dense.

Place the dough in a lightly oiled bowl, cover with a damp towel, and let it rise in a warm place for 1-2 hours or until doubled in size. This first rise develops the gluten and ensures a light, airy texture in the finished buns.

Step 4: Assemble and Steam the Buns

Punch down the risen dough and divide it into 12-14 equal pieces. Roll each piece into a circle about 3-4 inches in diameter, leaving the center slightly thicker than the edges. Place a spoonful of the char siu filling in the center of each dough circle.

To close the buns, pleat the edges by pinching and folding the dough inward in small sections, rotating the bun as you go until it is fully sealed. Place each finished bun on a small square of parchment paper to prevent sticking during steaming.

Arrange the buns in a steamer basket, leaving 1-2 inches of space between each one to allow for expansion. Steam over boiling water for 15-20 minutes until the dough is puffed and the buns are fully cooked through. Avoid opening the steamer lid during cooking, as this can cause the buns to deflate.

Remove the buns from the steamer and garnish with thinly sliced 3 whole Green Onions before serving warm.

Make-Ahead Tips for This Dish

Dough Prep Ahead

You can prepare the dough up to 24 hours in advance. After kneading, place it in an oiled bowl, cover tightly with plastic wrap, and refrigerate. Cold fermentation actually enhances flavor development. Just bring it to room temp before shaping. 💡

Filling Prep Ahead

The char siu filling keeps beautifully for 2 days in the fridge. Store it in an airtight container to prevent drying. I often make extra filling and freeze it in portions for up to 1 month—perfect for quick meals.

Assemble Before Steaming

Shape and fill the buns up to 4 hours before steaming. Place them on parchment squares, cover with a damp towel, and refrigerate. This lets the dough relax while you finish other prep work. Remove from fridge 30 minutes before cooking.

Freezing Uncooked Buns

Arrange uncooked buns on a tray, freeze solid for 1 hour, then transfer to a freezer bag. They’ll keep for 1 month. Steam from frozen—just add 5 extra minutes to the cooking time. No thawing needed! ❄️

Reheating Cooked Buns

Steam leftover buns for 5-7 minutes until hot and puffy. Avoid microwaving, as it makes the dough rubbery. I always keep a stash in the freezer for those dim sum cravings that hit out of nowhere.
