Vietnamese Steamed Pork Buns Recipe: Pillowy Bao With Garlic Pork Filling

These soft, fluffy buns deliver authentic Vietnamese flavors in every bite. The secret lies in the balance of sweet, savory pork filling and perfectly steamed dough.

I’ve refined this method to ensure pillowy texture and rich garlic-pork filling. The result is a dish that’s both comforting and impressive, with traditional techniques made accessible.

Ingredients for Vietnamese Steamed Pork Buns

Authentic Vietnamese flavors start with these carefully balanced ingredients for perfect steamed buns every time.

The flour is foundational—King Arthur or Bob’s Red Mill all-purpose deliver consistent results. For the pork, ground pork shoulder offers ideal fat content for juicy filling. Asian markets carry superior fish sauce brands like Red Boat, but most well-stocked supermarkets now stock quality options. Fresh ginger and garlic are non-negotiable for authentic flavor—avoid pre-minced jars.

No ground pork? Ground chicken or turkey work in a pinch, though flavor will differ. For fish sauce substitutions, soy sauce plus a pinch of MSG approximates the umami. Out of green onions? Shallots or chives add similar brightness. The sesame oil can be swapped with perilla oil for a Korean twist, but it changes the flavor profile. Don’t skip the cornstarch—it keeps the filling juicy without being soggy.

Uncooked filling keeps 24 hours refrigerated, dough 12 hours (before shaping). Steamed buns freeze beautifully for 3 months—reheat by steaming from frozen. Always use parchment paper when steaming to prevent sticking. Leftovers? Re-steam to revive that pillowy texture.

Step-by-Step Instructions for Vietnamese Steamed Pork Buns

Master the art of pillowy bao with this precise method for dough and filling.

Step 1: Activate Yeast and Prepare Dough

In a stand mixer bowl, combine the 1 cup warm water, 2 tsp instant yeast, and 0.25 cup granulated sugar. Let sit for 5-7 minutes until foamy—this confirms yeast activation. The mixture should develop a thick, bubbly layer on top.

Add the 3 cups all-purpose flour, 1 tsp baking powder, and ½ tsp salt (reserve the remaining salt for filling). Mix on low with the dough hook until combined, then increase to medium speed for 8-10 minutes until smooth and elastic. The dough should pull away from bowl sides but remain slightly tacky.

Step 2: Create the Garlic Pork Filling

Heat the 1 tbsp neutral oil in a skillet over medium-high heat. Add the 1 lb ground pork, breaking it up with a wooden spoon. Cook for 5-6 minutes until no pink remains and the pork starts to brown.

Stir in the minced 6 cloves garlic cloves, 1 tbsp fresh ginger, and sliced 4 whole green onions. Add the 2 tbsp fish sauce, 2 tbsp soy sauce, remaining ½ tsp salt, and 1 tbsp cornstarch. Cook for 2-3 minutes until thickened. Finish with 1 tbsp sesame oil and cool completely.

Step 3: Shape and Fill the Buns

Turn the rested dough onto a lightly floured surface and divide into 12 equal portions (about 70g each). Roll each into a ball, then flatten into a 4-inch circle with a rolling pin, leaving the center slightly thicker than the edges.

Place 1-2 tbsp of cooled pork filling in the center of each dough circle. Pleat the edges upward, pinching to seal tightly at the top while gently rotating the bun. The pleats should be even and the seal completely closed to prevent filling leakage during steaming.

Step 4: Proof and Steam to Perfection

Arrange the shaped buns on parchment squares in a steamer basket, leaving 1 inch between each. Cover and let proof for 30-45 minutes until puffed by about 50%. The buns should look noticeably larger but still hold their shape.

Bring 2 inches of water to a boil in a pot fitted with the steamer. Steam the buns in batches for 12-15 minutes with the lid on. They’re done when the dough is translucent and the buns have expanded fully. Avoid opening the lid during steaming to prevent temperature drops.

Essential Equipment for Great vietnamese steamed pork buns

Steamer Basket

A bamboo steamer is ideal for these buns, as it allows steam to circulate evenly. I recommend a 10-inch diameter for home use—it fits most pots. Look for EcoNest or Helen’s Asian Kitchen brands for quality. Line with parchment paper to prevent sticking. 💡

Stand Mixer

Kneading dough by hand is possible, but a stand mixer with dough hook saves time and ensures consistent texture. I use my KitchenAid for 8-10 minutes on medium speed. The dough should pull away from the bowl but remain slightly tacky.

Digital Scale

Precision matters for even buns. A digital kitchen scale helps divide dough into 12 equal portions (about 70g each). I prefer OXO or Escali for accuracy. Weighing also ensures your filling portions are consistent.

Rolling Pin

A French rolling pin (without handles) gives you the best control for rolling thin, even dough circles. Roll each piece to about 4-inch diameter, keeping the center slightly thicker than the edges. This helps the buns puff properly during steaming.

Parchment Paper

Cut parchment into 3-inch squares to place under each bun before steaming. This prevents sticking and makes removal easier. I like pre-cut parchment rounds for convenience. Avoid wax paper—it doesn’t handle the heat well.

Thermometer

Check your water temperature for yeast activation—it should be 110°F. A simple instant-read thermometer ensures you don’t kill the yeast with water that’s too hot. I keep a ThermoWorks in my kitchen drawer for this exact purpose. 🌡️
