⭐ Recipe Overview
- ⏱ Prep & Fermentation: ~2 days
- 🔥 Baking Time: 18–22 minutes
- 📊 Difficulty: Medium (patience required!)
- 🥐 Texture: flaky, airy, buttery layers
🧾 Ingredients
🥣 Dough
- 120 g active sourdough starter (100% hydration)
- 240 ml cold milk
- 40 g granulated sugar
- 10 g fine sea salt
- 500 g all-purpose or bread flour
- 40 g unsalted butter (softened)
🧈 Butter Layer (Lamination)
- 250 g high-quality unsalted butter (cold)
🥚 Egg Wash
- 1 egg
- 1 tbsp milk
👨🍳 Day 1 – Make the Dough
1. 🥣 Mix Ingredients
In a large bowl, combine:
- sourdough starter
- cold milk
- sugar
Add flour + salt and mix until a rough dough forms.
2. 🧈 Add Butter
Add softened butter and knead gently for 3–4 minutes until smooth.
⚠️ Do not over-knead (we don’t want tight gluten).
3. ⏳ First Rest
- Cover dough
- Rest for 30 minutes
4. 🔄 Stretch & Fold
Do 1 set of stretch and folds to strengthen dough.
5. 🌡️ Bulk Fermentation
Let dough rest for 4–5 hours at room temperature until slightly puffy (not doubled).
6. ❄️ Chill Overnight
Shape dough into a rectangle, wrap tightly, and refrigerate overnight.
👉 This makes lamination easier and cleaner.
🧈 Day 2 – Lamination (Butter Layers)
1. 🧈 Prepare Butter Block
Place butter between parchment paper and roll into a 7×7 inch square.
Chill until firm but still bendable.
2. 📦 Lock in Butter
Roll dough into a 10×10 inch square.
Place butter in center like a diamond and fold dough over it completely.
Seal edges well.
3. 🔁 Lamination Folds (3 Turns)
Roll dough into a rectangle and fold like a letter.
Then:
- Chill 30 minutes
- Repeat 3 total folds
👉 This builds flaky layers.
🔪 Shaping Croissants
1. Roll Dough
Roll dough to ¼ inch thickness.
2. Cut Triangles
Cut long triangles for croissants.
3. Shape
Gently stretch each triangle and roll tightly from base to tip.
Place on parchment-lined tray.
⏳ Final Proof (VERY IMPORTANT)
- Cover lightly
- Proof at 22–24°C (72–75°F)
- Time: 4–6 hours
They should look:
- Puffy
- Jiggly
- Clearly layered
⚠️ Do NOT rush this step—this decides flakiness.
🥚 Egg Wash & Bake
Brush gently with egg + milk mixture.
Bake at:
- 🔥 200°C / 390°F
- ⏱ 18–22 minutes
Bake until:
- deep golden brown
- crisp outside
- airy inside
💡 Pro Tips for Perfect Croissants
- Always keep butter cold during lamination
- If butter softens → chill immediately
- Use an active but not overly sour starter
- Don’t rush proofing (key for layers)
- Clean folds = better flakes
🧊 Storage
- Best eaten fresh (same day is ideal)
- Freeze baked croissants up to 2 months
- Reheat at 170°C (340°F) for 5–7 minutes
🍫 Variations
- 🍫 Chocolate: add chocolate batons before rolling
- 🥜 Almond: fill with almond cream after baking
- 🧀 Savory: add cheese before shaping
- 🍯 Sweet: brush with honey butter after baking
🏁 Final Thoughts
These sourdough croissants are the definition of patience paying off. Each bite is buttery, flaky, and full of delicate layers with a subtle tang from natural fermentation.
