Chinese Steamed Pork Buns Recipe: Fluffy Bao With Savory Pork Filling

This recipe delivers fluffy, pillowy bao buns filled with a savory pork mixture that melts in your mouth. The key is in the dough’s gentle rise and the perfect steaming technique.

I’ve refined this method to ensure the buns stay soft and the filling remains juicy. These are authentically delicious, with a texture that’s light yet satisfying.

Ingredients for Chinese Steamed Pork Buns

Fluffy dough and savory pork come together for authentic steamed buns at home.

The flour is the foundation—King Arthur or Gold Medal all-purpose are reliable choices. Yeast needs to be fresh (check the expiration date) and activated in warm water with sugar. For the pork filling, ground pork with 20% fat stays juicy during steaming. Look for it in the meat section at Whole Foods or any major supermarket. The ginger and garlic should be fresh, not powdered, for the best flavor.

No ground pork? Ground chicken or turkey work as substitutes, though the flavor will be milder. For a vegetarian option, mushrooms finely chopped mimic the texture. Soy sauce can be swapped for tamari (gluten-free) or coconut aminos. The rice vinegar adds tang—apple cider vinegar at equal parts is an easy swap. If you lack sesame oil, a neutral oil plus a dash of toasted sesame seeds adds similar depth.

The dough rests best in a warm spot (like an oven with the light on). Prepared filling can be refrigerated for up to 2 days before assembling. Steamed buns keep in the fridge for 3 days—reheat by steaming again. Freeze uncooked buns on a tray first, then transfer to a bag for up to 1 month.

Step-by-Step Instructions for Chinese Steamed Pork Buns

Master the technique for perfectly fluffy buns with a savory filling every time.

Step 1: Prepare and Activate the Dough

In a small bowl, combine the 2.25 tsp Active Dry Yeast, 0.25 cup Granulated Sugar, and 1.25 cups Warm Water. Stir gently and let sit for 5-7 minutes until the mixture becomes frothy and cloudy—this confirms the yeast is active and working properly.

In a large mixing bowl, add the 3 cups All-Purpose Flour and create a well in the center. Pour in the yeast mixture and 2 tbsp Vegetable Oil. Use a wooden spoon or your hands to mix until a shaggy dough forms. The dough should feel slightly sticky but pull away from the sides of the bowl.

Step 2: Knead and Proof the Dough

Turn the dough out onto a lightly floured surface dusted with extra all-purpose flour. Knead for 8-10 minutes until smooth and elastic. You’ll know it’s ready when you can stretch a small piece thin enough to see light through it without tearing (the windowpane test).

Place the dough in a lightly oiled bowl, turning to coat all sides with vegetable oil. Cover with a damp towel and let rise in a warm, draft-free place for 1 to 1.5 hours or until doubled in size. The dough should spring back slowly when pressed gently with a finger.

Step 3: Prepare the Savory Pork Filling

In a mixing bowl, combine the 1 lb Ground Pork, 4 whole Green Onions (thinly sliced), 1 tbsp Fresh Ginger (finely minced), and 3 cloves Garlic Cloves (minced). Add the 2 tbsp Soy Sauce, 1 tsp Sesame Oil, 1 tbsp Rice Vinegar, 1 tbsp Brown Sugar, and 0.5 tsp Salt.

Mix thoroughly in one direction until sticky and well combined—this ensures even distribution of flavors. For best texture, refrigerate the filling for 20-30 minutes while the dough proofs. This resting period allows the flavors to meld and the fat to firm up slightly for easier handling.

Step 4: Shape and Fill the Buns

Punch down the risen dough to release air and divide it into 12 equal portions (about 2.5 oz each). Roll each piece into a ball, then flatten into a 3-inch circle with a rolling pin, keeping the edges thinner than the center.

Place 1 rounded tablespoon of pork filling in the center of each dough circle. Pleat the edges upward, pinching as you go to seal completely. Twist the top slightly to ensure a tight seal—this prevents filling from leaking during steaming. Place each bun on a square of parchment paper.

Step 5: Steam to Perfection

Line a bamboo steamer with parchment paper, poking small holes for steam circulation. Arrange the buns 2 inches apart to allow for expansion. Bring 2 inches of water to a boil in a wok or large pot, then place the steamer on top. Cover and steam for 15-18 minutes.

Check that the buns have puffed to about 50% larger and the dough feels springy when pressed. Remove the lid carefully to avoid condensation dripping onto the buns. Let rest for 2 minutes in the steamer before serving to prevent collapsing. The filling should be cooked through and juicy, not pink.

Creative Variations of This Recipe

Sweet Red Bean Buns

Swap the pork filling for 1 cup sweet red bean paste (available at Asian markets or online). Reduce the dough portions to 2 oz each for smaller, dessert-sized buns. The paste should be thick and slightly sticky for easy shaping. 💛

Spicy Pork Variation

Add 1 tbsp chili crisp or Sichuan chili oil to the pork filling mixture. Include 1 tsp red pepper flakes for extra heat. Balance the spice with an additional 1 tsp brown sugar to round out the flavors.

Vegetable-Only Buns

Replace pork with a mix of 1 cup finely chopped shiitake mushrooms and ½ cup shredded cabbage. Sauté with 1 tbsp soy sauce and 1 tsp sesame oil before filling. This creates a lighter, veggie-packed version.

Char Siu Pork Buns

Use 1 lb diced char siu pork (Chinese BBQ pork) instead of ground pork. Add 1 tbsp hoisin sauce to the filling mixture for that classic sweet-savory flavor. This variation is popular in Cantonese dim sum. 🔥

Cheese and Pork

Mix ½ cup shredded cheddar or mozzarella into the pork filling for a fusion twist. The cheese melts beautifully during steaming, creating a gooey surprise inside. Kids especially love this version.

Mini Party Buns

Divide the dough into 24 small portions (about 1.25 oz each). Use 1 tsp pork filling per bun for bite-sized appetizers. Steam for 12-13 minutes since they’ll cook faster.
