Chinese Baked BBQ Pork Bun Recipe: Fluffy Buns With Sweet Glazed Filling

This recipe brings together tender char siu filling and fluffy baked buns in perfect harmony. The secret lies in slow-roasting the pork with a sweet glaze before wrapping it in soft, pillowy dough.

Each bite delivers a balance of savory meat and slightly sweet bread. The baking process creates a golden crust while keeping the inside remarkably light and airy.

The pork shoulder is non-negotiable here. Costco has great pre-cut strips, or ask your butcher to trim and slice a whole shoulder. Look for good marbling—it keeps the meat juicy during roasting. For the hoisin, Koon Chun is the gold standard, but Lee Kum Kee works in a pinch. The Chinese five spice is what makes char siu distinct (don’t skip it).

No pork shoulder? Pork butt works too, but trim off excess fat. Short on hoisin? Mix equal parts soy sauce and oyster sauce with a touch of honey. The dough can be made with bread flour instead of all-purpose for extra chew. For a shortcut, use store-bought char siu from an Asian market (just reheat before filling).

The pork filling keeps 4-5 days refrigerated, freezes for 3 months. Baked buns are best day-of but reheat well—steam them 5 minutes to restore fluffiness. Dough can be prepped a day ahead; let it proof in the fridge overnight.

Step-by-Step Instructions for Chinese Baked BBQ Pork Buns

Master the technique for perfect fluffy buns with a sweet, sticky pork filling.

Step 1: Prepare the Char Siu Pork Filling

Combine the 1.5 lb Pork Shoulder (cut into strips) with 0.5 cup Hoisin Sauce, 0.25 cup Honey, 3 tbsp Soy Sauce, 2 tbsp Brown Sugar, 1 tsp Chinese Five Spice Powder, and 3 cloves minced Garlic Cloves in a bowl.

Mix thoroughly until the pork is evenly coated. Cover and refrigerate for at least 2 hours (or overnight) to allow the flavors to penetrate deeply. This marinating step ensures the filling is packed with authentic char siu flavor.

When ready to cook, roast the pork at 375°F for 25-30 minutes until fully cooked and caramelized. Let it cool, then finely chop or shred for the filling.

Step 2: Activate the Yeast and Prepare the Dough

In a small bowl, dissolve the 2 tbsp Granulated Sugar in the 1 cup Warm Water (110°F). Sprinkle the 2.25 tsp Instant Yeast over the surface and let it sit for 5-10 minutes until foamy—this confirms the yeast is active.

In a large mixing bowl, combine the 3 cups All-Purpose Flour, 0.25 cup Whole Milk (warmed), 2 tbsp Unsalted Butter (softened), and ½ tsp Salt. Pour in the yeast mixture and knead for 8-10 minutes until the dough is smooth and elastic.

Step 3: First Rise and Shape the Buns

Place the dough in a greased bowl, cover with a damp towel, and let it rise in a warm place for 1-2 hours or until doubled in size. The dough should spring back slowly when pressed with a finger.

Once risen, punch down the dough and divide it into 12 equal portions. Roll each piece into a ball, then flatten into a 3-inch circle. Place a spoonful of the cooled pork filling in the center of each dough circle.

Step 4: Assemble, Second Rise, and Bake

Gather the edges of the dough around the filling and pinch to seal tightly. Place each bun seam-side down on a parchment-lined baking sheet, spacing them 2 inches apart. Cover with a damp towel and let rise for another 30-45 minutes until puffy.

Preheat the oven to 350°F. Brush the buns lightly with a beaten Large Egg (mixed with the remaining ½ tsp Salt). Bake for 18-20 minutes until golden brown and the internal temperature reaches 190°F.

Remove from the oven and let cool for 10 minutes before serving. The buns should be light, fluffy, and filled with the sweet-savory pork mixture.

Troubleshooting Great chinese baked bbq pork bun

Dough Won’t Rise

If your dough isn’t rising, check your yeast first. I always use 110°F water—too hot kills yeast, too cold slows activation. If it’s inactive, your yeast might be expired. Also, ensure your kitchen is warm enough (75-80°F ideal). A trick: place the bowl in your oven with the light on. 💡

Dry or Dense Buns

Over-kneading or insufficient rising causes this. Knead just until smooth (8-10 minutes max). Let it double in size—this can take 2 hours in cooler kitchens. I often set a timer to avoid rushing this step.

Filling Leaks Out

Seal those edges tightly! Pinch and twist the dough to create a secure seal. Don’t overfill—use about 2 tbsp pork per bun. Chill the filling before wrapping to reduce leakage. I also brush the dough edges with water before sealing for extra grip.

Buns Brown Too Fast

Lower your oven rack and tent with foil if they’re browning before 18 minutes. I bake mine on the middle rack at 350°F. The egg wash can cause rapid browning, so apply it thinly just before baking.

Uneven Cooking

Rotate your baking sheet halfway through for even heat distribution. Ensure your oven is fully preheated and avoid opening the door during the first 12 minutes. I use a pizza stone for consistent bottom heat. ✨

Bland Filling

Did you marinate the pork long enough? I let mine sit overnight for maximum flavor. If it’s still mild, add 1 extra tbsp hoisin or 1 tsp five-spice powder to the filling before wrapping. Fresh garlic makes a huge difference too.
