Yield

  • 1 large loaf (8–10 slices)

Ingredients

Dough

  • 500g bread flour
  • 100g active sourdough starter
  • 4 large eggs (room temperature)
  • 60ml whole milk
  • 75g granulated sugar
  • 10g salt
  • 170g unsalted butter, softened and cut into cubes

Egg Wash

  • 1 egg
  • 1 tablespoon milk

Equipment

  • Stand mixer (recommended)
  • Large mixing bowl
  • Loaf pan (9×5 inch)
  • Kitchen scale
  • Pastry brush

Step 1: Mix the Dough

In the bowl of a stand mixer combine:

  • Bread flour
  • Sugar
  • Salt

Add:

  • Active sourdough starter
  • Eggs
  • Milk

Mix on low speed until a rough dough forms.

Continue mixing for 5–7 minutes until the dough begins to develop strength.


Step 2: Add the Butter

Add softened butter one cube at a time.

Allow each piece to fully incorporate before adding the next.

Continue mixing for 10–15 minutes.

The dough will become:

  • Smooth
  • Elastic
  • Slightly sticky
  • Glossy

Perform a windowpane test to check gluten development.


Step 3: Bulk Fermentation

Transfer dough to a lightly greased bowl.

Cover and let rise at room temperature for 5–7 hours.

The dough should become puffy and increase noticeably in size.


Step 4: Cold Fermentation

Cover tightly and refrigerate overnight (8–12 hours).

This step improves flavor and makes the dough easier to shape.


Step 5: Shape the Brioche

Remove dough from the refrigerator.

Turn onto a lightly floured surface.

Divide into:

  • 8 equal portions

Shape each piece into a smooth ball.

Arrange the balls in a greased loaf pan.

This creates the classic pull-apart brioche look.


Step 6: Final Proof

Cover loosely.

Allow to rise for 4–6 hours or until doubled and puffy.

The dough should rise above the edge of the loaf pan.


Step 7: Egg Wash

Whisk together:

  • 1 egg
  • 1 tablespoon milk

Brush gently over the surface.

This creates a beautiful golden finish.


Step 8: Bake

Preheat oven to:

375°F (190°C)

Bake for:

30–35 minutes

If the top browns too quickly, loosely cover with foil.

The internal temperature should reach approximately:

190°F (88°C)


Step 9: Cool

Allow the loaf to cool in the pan for 10 minutes.

Transfer to a wire rack and cool completely before slicing.
