Step-by-Step Instructions

Step 1: Feed Your Starter

About 4–6 hours before mixing the dough, feed your sourdough starter.

The starter should be active, bubbly, and doubled in size before use.

To test readiness, drop a spoonful into water. If it floats, it’s ready.

Step 2: Mix the Dough

In a large bowl combine:

• Active sourdough starter
• Warm milk
• Egg
• Sugar

Whisk until smooth.

Add:

• Bread flour
• Salt

Mix until a shaggy dough forms.

Add softened butter and continue mixing until incorporated.

The dough may seem sticky at first but will become smoother as kneaded.

Step 3: Knead the Dough

By Hand

Transfer the dough to a lightly floured surface.

Knead for 10–12 minutes until smooth and elastic.

Using a Stand Mixer

Knead with a dough hook on medium speed for 6–8 minutes.

The finished dough should be soft and slightly tacky but not overly sticky.

Step 4: First Fermentation (Bulk Rise)

Place the dough in a lightly greased bowl.

Cover with plastic wrap or a damp towel.

Allow the dough to rise at room temperature for:

8–12 hours

The dough should nearly double in size.

The exact time will depend on room temperature and starter strength.

Step 5: Divide and Shape

Turn the dough onto a lightly floured surface.

Gently deflate the dough.

Divide into 8 equal portions.

Each piece should weigh approximately 95–100 grams.

Shape each piece into a smooth ball by pulling the dough edges underneath and rotating.

Place on a parchment-lined baking sheet.

Leave 2–3 inches of space between each bun.

Step 6: Flatten Slightly

Using the palm of your hand, gently flatten each dough ball.

This helps create the classic hamburger bun shape.

The buns will puff up considerably during the final rise and baking.

Step 7: Second Rise

Cover loosely with lightly oiled plastic wrap.

Allow the buns to rise for:

2–3 hours

They should become noticeably puffy and almost doubled in size.

Step 8: Prepare for Baking

Preheat the oven to:

375°F (190°C)

In a small bowl whisk together:

• 1 egg
• 1 tablespoon milk

Brush each bun gently with egg wash.

Sprinkle with sesame seeds or your preferred topping.

Step 9: Bake

Bake for:

18–22 minutes

The buns should be deeply golden brown and reach an internal temperature of approximately:

190–195°F (88–90°C)

The tops should be shiny and beautifully browned.

Step 10: Cool Completely

Transfer the buns to a wire rack.

Allow them to cool for at least:

30 minutes

before slicing.

This prevents the crumb from becoming gummy.

Baker’s Tips for Perfect Buns

Use Bread Flour

Bread flour provides better structure and chew than all-purpose flour.

Don’t Over-Flour

The dough should remain soft and slightly tacky.

Adding too much flour can make the buns dense.

Shape Tightly

A tight surface tension creates taller, more uniform buns.

Allow Full Fermentation

Proper fermentation develops flavor and improves texture.

Overnight Refrigerator Method

After bulk fermentation:

1. Cover the dough tightly.
2. Refrigerate overnight.
3. Shape buns the next day.
4. Allow 3–4 hours for the final rise.
5. Bake as directed.

This method creates even deeper sourdough flavor.
