Juicy pork bao zi are fluffy steamed buns filled with seasoned ground pork. A high protein, family breakfast classic with fresh, savory flavor.
In a large bowl, dissolve 2 tbsp sugar in 1 cup warm water, then sprinkle in instant yeast. Allow to bloom for 10 minutes until frothy.
Add all-purpose flour to the yeast mixture and knead for 8–10 minutes until smooth and elastic. Cover and let rise in a warm place for at least 1 hour, or until doubled in size.
While dough rises, combine ground pork, chopped green onions, soy sauce, sesame oil, oyster sauce, salt, white pepper, and 1 tsp sugar. Mix thoroughly until sticky and cohesive.
Punch down the dough and divide into 12 even pieces. Roll each into a ball, then flatten into 4-inch rounds. Keep unused dough covered to prevent drying.
Place 2 tablespoons of pork filling in the center of each dough round. Pleat and pinch the edges to seal the buns tightly at the top.
Arrange assembled bao zi on parchment squares, cover lightly, and let rest for 20 minutes to proof.
Steam the buns over boiling water for 15 minutes on medium-high heat, ensuring enough space between each bun for expansion. Let rest for 5 minutes with the lid slightly ajar before serving.
