Step-by-Step Instructions to Make Sourdough Croissant Bread

Step 1: Prepare the Dough

In a mixing bowl, combine sourdough starter, milk, sugar, and salt.
Gradually add flour, mixing until a soft dough forms.
Knead for 8-10 minutes, until smooth and elastic.
Cover and let rest for 2-4 hours at room temperature, until slightly puffed.

Step 2: Prepare the Butter Block

Place cold butter between two sheets of parchment paper.
Roll into a thin rectangle and chill in the fridge.

Step 3: Laminate the Dough (Butter Layering)

Roll out the dough into a large rectangle.
Place the butter block in the center and fold the dough over it.
Roll out and fold into thirds (like folding a letter).
Chill for 30 minutes, then repeat the rolling and folding three more times.

Step 4: Shape & Proof

Roll out the laminated dough and shape into a loaf.
Place into a greased loaf pan and cover.
Let rise at room temperature for 8-12 hours (overnight is best).

Step 5: Bake & Serve

Preheat oven to 375°F (190°C).
Brush with egg wash (if using).
Bake for 30-35 minutes, until golden brown.
Let cool for 10 minutes, then slice and enjoy warm!

Expert Tips for the Best Sourdough Croissant Bread

Use active sourdough starter – The dough needs a strong starter for the best rise.
Keep the butter cold – This is key to creating flaky layers.
Don’t rush the fermentation – A slow overnight rise develops deep flavor.
Want a richer taste? – Add 1 teaspoon of vanilla extract or cinnamon to the dough.
For an ultra-crispy crust – Bake with steam (place a pan of hot water in the oven).

Fun Variations of Sourdough Croissant Bread

Chocolate Croissant Bread – Add chocolate chips between layers.
Cinnamon Sugar Croissant Bread – Sprinkle cinnamon and sugar before rolling.
Savory Garlic & Herb Croissant Bread – Mix in garlic powder and rosemary.

FAQ Section

1. Can I make this croissant bread without dairy?
Yes! Use vegan butter and plant-based milk for a dairy-free version.

2. Can I skip the lamination process?
Skipping lamination will result in a less flaky, more traditional sourdough texture.

3. Can I use sourdough discard instead of active starter?
For best results, use active starter. Discard won’t provide enough rise.
