Ingredients

Servings:4

For the bao buns:

2 ½ cups all-purpose flour

2 tsp instant yeast

2 tbsp sugar

½ tsp baking powder

¾ cup warm milk

2 tbsp neutral oil

For the chicken:

4 boneless chicken thighs

1 cup buttermilk

1 cup all-purpose flour

½ cup cornstarch

1 quart neutral oil, for frying

For the Szechuan glaze:

2 tbsp chili crisp

1 tbsp honey

1 tbsp soy sauce

1 tsp Szechuan peppercorns, toasted and ground

To finish:

¼ cup mayonnaise mixed with 1 tsp togarashi

1 cup quick cucumber pickles

Method

Make the bao dough. Combine flour, yeast, sugar, and baking powder, then mix in the warm milk and oil to form a soft dough. Knead 8 minutes until smooth. Cover and proof until doubled, about 1 hour.
Shape and steam. Roll the dough into ovals, brush with oil, and fold over a chopstick to make the classic folded bao shape. Proof 30 minutes, then steam over simmering water 10 minutes. Keep the lid wrapped in a towel so condensation doesn't drip and pockmark the buns — a smooth, cloud-white surface is the goal.
Dredge the chicken. Soak the thighs in buttermilk, then dredge in the flour-cornstarch mix, pressing hard so craggy bits form. The cornstarch and craggy dredge are what fry up shatteringly crisp.
Fry at 350°F for 6-7 minutes until deep golden and 165°F internal. Rest on a wire rack.
Glaze. Warm the chili crisp, honey, soy, and ground Szechuan pepper into a glaze and toss the fried chicken to coat. The peppercorn brings the signature numbing tingle against the heat.
Assemble. Open each bao, swipe with togarashi mayo, tuck in the glazed chicken, and top with cucumber pickles. Serve immediately while the bun is warm and the chicken is crisp.

Chef Notes

The most important thing: Wrap the steamer lid in a towel. Dripping condensation ruins the smooth bao surface.
Short on time? Store-bought frozen bao buns are genuinely good — steam and fill. That drops this to a 45-minute recipe.
Fry to 165°F internal and glaze at the last second so the crust stays crisp.
Szechuan peppercorn is numbing, not hot — the chili crisp brings the heat. You want both.
Proof the dough somewhere warm; under-proofed bao steam up dense.

Common Substitutions

Ingredient	Substitution	Notes
Homemade bao	Frozen store-bought bao	Steam per package; cuts an hour of work
Chicken thigh	Chicken breast	Leaner; fry to 160°F and rest to avoid drying
Buttermilk	Milk + 1 tbsp vinegar	The acid tenderizes and helps the dredge cling
Chili crisp	Sriracha + chili flakes in oil	Approximates the crunchy, spicy glaze

What You're Practicing

Steamed bao is a bread-baking skill in a different medium — you're proofing a yeasted, enriched dough and setting it with steam instead of dry oven heat. The dough-handling and proofing instincts transfer straight to dinner rolls and buns. Visit Techniques for dough and frying fundamentals.

You're also practicing the buttermilk-dredge fried chicken method — soak in acid and salt, dredge in a cornstarch-cut flour, and fry at a steady 350°F. It's the backbone of fried chicken everywhere, from sandwiches to Nashville hot.
