Shokupan is Japan's beloved ultra-soft white bread, prized for its cottony crumb and pillowy texture. The secret is the tangzhong (water-roux) starter that locks in moisture for an incredibly tender loaf with subtle sweetness, perfect for breakfast toast, katsu sandos, or thick slices with jam.

Ingredients
For the tangzhong (water roux)
- 3 tbsp bread flour (25 g)
- 5 tbsp water (75 ml)
For the dough
- 2 3/4 cups bread flour (350 g)
- 2 1/4 tsp instant yeast (7 g)
- 1/4 cup granulated sugar (50 g)
- 1 tsp fine sea salt (6 g)
- 1 large egg, room temperature
- 1/2 cup warm whole milk (120 ml)
- 1/3 cup warm water (80 ml)
- 2 tbsp unsalted butter, softened (30 g)
For finishing
- 1 tbsp unsalted butter, melted
- 1/2 tsp neutral oil, for greasing
Directions
- Make the tangzhong: whisk the bread flour and water in a small saucepan over medium-low heat and cook, stirring constantly, for 2 to 3 minutes until a thick, smooth paste forms. Transfer to a small bowl and let cool completely to room temperature.
- In the bowl of a stand mixer, combine the bread flour, instant yeast, sugar, and salt. Add the cooled tangzhong, egg, warm milk, and warm water. Mix on low speed with the dough hook for 2 minutes until a shaggy dough forms, then increase to medium and knead for 8 to 10 minutes until smooth.
- Add the softened butter one tablespoon at a time, kneading well between additions, then continue kneading for 5 to 7 minutes until the dough is silky, elastic, and passes the windowpane test (a small piece stretched thin should not tear).
- Shape the dough into a smooth ball, place in a lightly oiled bowl, cover with plastic wrap, and let rise in a warm spot for 60 to 90 minutes until doubled in size.
- Punch down the dough and divide into 3 equal portions. Roll each piece into an oval, fold the two short sides toward the center, then roll tightly from top to bottom into a log. Place the logs seam-side down, evenly spaced, in a greased Pullman loaf pan.
- Cover the pan and let the dough proof a second time for 40 to 50 minutes until it reaches about 80 percent of the pan's height. Meanwhile, preheat the oven to 350°F (175°C).
- Bake for 30 to 35 minutes, tenting loosely with foil at the 20-minute mark if the top browns too quickly, until the crust is golden and an instant-read thermometer reads 190°F (88°C) in the center.
- Brush the hot loaf immediately with melted butter. Cool in the pan for 10 minutes, then turn out onto a wire rack and cool completely for at least 1 hour before slicing with a serrated bread knife.
Cook’s Notes
- The windowpane test is the best way to confirm proper gluten development: stretch a small dough piece thin; if light passes through without tearing, it is ready.
- Use a Pullman pan with a lid for the iconic square-sided loaf; baking without the lid produces the classic gently domed top.
- Always cool the tangzhong fully before adding it to the dough, or it can deactivate the yeast and prevent rising.
- Bread flour is essential for the chewy-yet-soft texture; all-purpose flour will yield a more crumbly crumb.
- Day-old shokupan slices make outstanding egg-in-a-hole, French toast, or katsu sando sandwiches with crusts trimmed.
