Croissants are one of the most beloved pastries in the world, known for their delicate layers, crisp golden crust, and rich buttery flavor. While traditional croissants are typically made using commercial yeast, a sourdough croissant takes this classic pastry to a whole new level. By incorporating a sourdough starter, these croissants not only develop a deeper, more complex flavor, but they also offer digestive benefits thanks to the natural fermentation process.
But what exactly makes sourdough croissants unique? Unlike regular croissants, which rely on store-bought yeast for a quick and predictable rise, sourdough croissants ferment slowly over time, allowing natural bacteria and wild yeasts to enhance the dough’s structure and taste. This slow fermentation process results in a pastry that is not only more flavorful but also lighter and easier to digest, as the long fermentation helps break down gluten and phytic acid.
Sourdough Croissants vs. Regular Croissants: What’s the Difference?
If you’ve ever baked or eaten a classic croissant, you might be wondering how a sourdough croissant differs from its conventional counterpart. The key differences lie in three main aspects:
1. Fermentation Process
- Regular croissants use instant or dry yeast, allowing the dough to rise in just a few hours.
- Sourdough croissants rely on a natural sourdough starter, meaning the dough ferments overnight or longer, leading to a richer, more complex taste.
2. Flavor Profile
- Traditional croissants have a mild, slightly sweet taste with a strong buttery aroma.
- Sourdough croissants have a deeper, slightly tangy flavor, thanks to the wild fermentation process. This enhances the natural sweetness of the dough while adding a subtle umami complexity.
3. Health Benefits
- Fermentation breaks down gluten, making sourdough croissants easier to digest than regular ones.
- Sourdough also contains prebiotics and probiotics, which can improve gut health.
- The slow fermentation reduces phytic acid, making minerals more bioavailable for better nutrient absorption.

Essential Ingredients and Tools for Perfect Sourdough Croissants
Baking sourdough croissants is an art that requires precision, patience, and the right ingredients and tools. Since sourdough croissants depend on natural fermentation and laminated layers, using high-quality ingredients and proper equipment will greatly impact the final texture, taste, and flakiness of your pastry.
In this section, we will break down the essential ingredients that contribute to a perfect sourdough croissant, as well as the tools that make the process smoother and more efficient.
Key Ingredients: What Makes a Perfect Sourdough Croissant?
The ingredients in sourdough croissants are similar to those in traditional croissants, but their quality and role are crucial for a successful fermentation, lamination, and baking process. Let’s go over each essential component.
1. Sourdough Starter (Active & Bubbly)
The sourdough starter is the heart of this recipe. Unlike regular croissants that use commercial yeast for leavening, sourdough croissants depend on wild yeast and lactic acid bacteria to ferment the dough naturally.
👉 Key Points:
- Use a mature, active, and bubbly starter (it should double in size within 4-6 hours of feeding).
- A healthy starter provides rise, complex flavor, and improved digestibility.
- If your starter is sluggish, give it a few extra feedings before using it in your dough.
💡 Pro Tip: If your starter is too acidic, your croissants may turn out too tangy. Adjust by using a mildly fed starter or reducing fermentation time.
2. High-Protein Flour (For Gluten Development)
Flour provides structure and elasticity to the dough, allowing it to stretch without breaking during the lamination process. The best flour for sourdough croissants is high in protein (12-14%), which ensures strong gluten development.
👉 Best Flour Choices:
- Bread flour (High in protein and elasticity)
- All-purpose flour (mixed with bread flour) for a slightly softer texture
- French-style T55 or T65 flour (for a more authentic croissant)
💡 Pro Tip: Avoid using low-protein flour like cake flour, as it won’t develop enough gluten strength to support the layers.
3. High-Quality Butter (For Lamination & Flakiness)
Butter is one of the most important ingredients in croissants. It is responsible for the distinct laminated layers, rich buttery flavor, and delicate crispiness.
👉 Choosing the Right Butter:
- Use high-fat butter (at least 82% fat content) for better lamination.
- European-style butter (like Plugrá, Président, or Kerrygold) works best because it has a lower water content, making the layers crispier and less greasy.
💡 Pro Tip: Cold butter is essential during lamination. Too soft, and it will blend into the dough; too hard, and it will break when rolling.
4. Sugar, Salt, and Milk (For Flavor & Structure)
Although croissants aren’t overly sweet, these ingredients play a crucial role:
- Sugar: Adds a slight sweetness and helps with caramelization for a golden crust.
- Salt: Balances flavors and strengthens gluten development.
- Milk: Softens the dough and enriches the texture. Some recipes use water instead, but milk adds a richer taste and color.
💡 Pro Tip: If you want extra softness, you can replace part of the milk with cream for a more indulgent croissant.
Important Tools: The Right Equipment for a Flawless Bake
To make sourdough croissants, having the right tools can make the difference between perfectly layered pastries and a failed attempt. These tools help ensure precision, ease, and consistency in your croissant-making process.
1. Rolling Pin (For Laminating Dough)
A sturdy, heavy rolling pin is essential for rolling out the dough during the lamination process. Since croissant dough requires multiple folds and layers, using the right rolling pin makes it easier to achieve an even, smooth thickness.
👉 Best Options:
- A French-style rolling pin (tapered ends) gives more control.
- A heavy-duty stainless steel rolling pin helps apply even pressure.
💡 Pro Tip: Lightly flour your rolling pin but avoid over-flouring, as it can dry out the dough.
2. Dough Scraper (For Handling & Shaping)
A dough scraper (or bench knife) is one of the most useful tools when handling sticky sourdough croissant dough. Since sourdough tends to be softer than regular dough, a scraper helps:
- Lift and fold the dough without tearing it.
- Clean excess flour from your work surface.
- Cut and shape croissants evenly.
💡 Pro Tip: Use a metal dough scraper for shaping and cutting, and a plastic scraper for handling delicate dough.
3. Baking Stone or Tray (For Even Baking)
Croissants bake best on a preheated baking stone or a heavy-duty baking tray that retains heat evenly. This helps ensure that your croissants get consistent oven spring, producing an airy, crispy texture.
👉 Why Use a Baking Stone?
- It absorbs and distributes heat evenly, preventing undercooked bottoms.
- It mimics a professional bakery oven, ensuring the croissants bake crispy and golden.
💡 Pro Tip: If you don’t have a baking stone, use an inverted baking tray to create a similar effect.
4. Sharp Knife or Pastry Cutter (For Precise Cuts)
Croissant shaping requires clean, precise cuts to help the layers bake properly. A dull knife presses the layers together, making it harder for the croissants to rise.
👉 Best Cutting Tools:
- Sharp chef’s knife (for straight, precise cuts)
- Pizza cutter (for even triangle shapes)
- Pastry wheel (for perfect, uniform cuts)
💡 Pro Tip: Chill the dough before cutting to keep the butter layers intact.
Final Thoughts: The Secret to Success in Sourdough Croissants
Using the right ingredients and tools is the foundation of making perfect, bakery-quality sourdough croissants. By focusing on high-protein flour, a well-fed starter, premium butter, and essential tools, you’ll set yourself up for success in crafting light, flaky, and flavorful croissants.

Step-by-Step Guide to Making Sourdough Croissants
Making sourdough croissants is a rewarding process, but it requires patience, precision, and time. Unlike regular croissants, which use commercial yeast for a quick rise, sourdough croissants rely on wild fermentation, which takes longer but results in a deeper, more complex flavor.
This guide will walk you through the four essential steps to achieving perfectly flaky, buttery, and airy sourdough croissants.
Step 1: Preparing the Dough
1. Mixing the Ingredients
Start by combining the key ingredients to form the dough:
- 500g bread flour (high-protein)
- 100g active sourdough starter
- 200ml whole milk (room temperature)
- 50g sugar
- 10g salt
- 50g softened butter
- 1 egg (optional, for extra richness)
👉 Mixing Method:
- In a large bowl, mix the flour, starter, sugar, and milk.
- Knead for 5-8 minutes until the dough starts to come together.
- Add the salt and softened butter, then knead for another 5-7 minutes until the dough becomes smooth and elastic.
💡 Pro Tip: The dough should feel soft but not sticky. If it’s too dry, add a tablespoon of milk; if too wet, sprinkle in a bit more flour.
2. Bulk Fermentation (Overnight Rest)
Once the dough is fully mixed, it’s time for bulk fermentation, which allows the natural wild yeast to develop flavor and structure.
- Place the dough in a lightly greased bowl.
- Cover and let it ferment at room temperature for 3-4 hours.
- Transfer to the fridge and cold ferment overnight (8-12 hours).
💡 Why Refrigerate?
- Slows down fermentation, enhancing the flavor and texture.
- Firms up the dough, making lamination easier.
Step 2: Laminating the Dough
Lamination is the most critical step in croissant-making. This is where you encase butter inside the dough and create multiple layers to achieve the flaky, crispy texture.
1. Preparing the Butter Block
- Use 250g of high-fat butter (82%+ fat content).
- Flatten it into a 15×15 cm (6×6 inches) square between two sheets of parchment paper.
- Chill in the fridge for 30 minutes before laminating.
💡 Pro Tip: If the butter is too hard, it will crack while rolling. If it’s too soft, it will melt into the dough. Aim for a firm but pliable texture.
2. Rolling & Enclosing the Butter
- Take your chilled dough and roll it into a 30×20 cm (12×8 inches) rectangle.
- Place the butter block in the center, folding the dough over it like an envelope.
- Seal the edges tightly to prevent butter from leaking.
3. Creating the Flaky Layers (Folding Process)
Now, we create layers by folding the dough in a technique called a tri-fold (book fold):
- Roll out the dough into a 45×20 cm (18×8 inches) rectangle.
- Fold one-third of the dough over itself, then fold the other third on top (like a letter).
- Rotate the dough 90 degrees, chill for 30 minutes, then repeat twice more.
💡 Why Chill Between Folds?
- Prevents butter from melting into the dough.
- Allows gluten to relax, making rolling easier.
After three folds, you will have 81 thin layers of butter and dough, which will create the signature flaky texture when baked.
Step 3: Shaping and Proofing
1. Cutting and Rolling the Croissants
- Roll out the laminated dough into a 40×25 cm (16×10 inches) rectangle.
- Using a sharp knife or pastry cutter, cut triangles about 8 cm wide at the base and 20 cm long.
- Gently stretch each triangle before rolling.
- Roll from the base to the tip, ensuring a snug but not tight roll to allow room for expansion.
💡 Pro Tip: If you want a more open, honeycomb-like crumb, roll the croissants loosely so they proof properly.
2. Cold Proofing (Final Fermentation)
Sourdough croissants require a long, slow proofing process to develop flavor and structure.
- Arrange croissants on a parchment-lined baking tray.
- Cover with a light cloth and let them proof at room temperature for 2 hours.
- Transfer to the fridge and cold proof overnight (8-12 hours).
💡 Why Cold Proofing?
- Enhances flavor complexity.
- Allows the layers to set properly, preventing butter from leaking.
Step 4: Baking to Perfection
1. Applying the Egg Wash
Before baking, apply an egg wash to give the croissants a golden, glossy finish.
- Beat 1 egg with 1 tablespoon of milk.
- Brush a thin layer over the croissants, avoiding excess drips.
💡 Pro Tip: Do not apply egg wash too early—only brush right before baking to avoid drying out the dough.
2. Baking at the Right Temperature
Preheat your oven to 190°C (375°F) for at least 30 minutes before baking.
- Bake croissants at 190°C (375°F) for 10 minutes, then reduce to 170°C (340°F) and bake for another 10-12 minutes.
- Croissants are done when they are deep golden brown and sound hollow when tapped.
💡 Pro Tip: To ensure an even bake, rotate the tray halfway through baking.
3. Cooling & Enjoying
- Let the croissants cool on a wire rack for at least 15 minutes before eating.
- This allows the internal structure to set, making the texture light and crisp.
🥐 Congratulations! You’ve just made authentic sourdough croissants from scratch. 🎉
Pro Tips and Common Mistakes to Avoid When Making Sourdough Croissants
Baking sourdough croissants requires patience, precision, and attention to detail. While the process may seem complex, following expert tips and avoiding common mistakes will help you achieve flaky, golden, and beautifully layered croissants every time.
In this section, we’ll cover pro tips for success and provide solutions to common problems that bakers encounter when making sourdough croissants.
Pro Tips for Success
Achieving bakery-quality sourdough croissants is all about fermentation control, precise lamination, and maintaining the right dough texture. Here are some expert tips to help you master the process:
1. Use an Active Sourdough Starter for a Good Rise
Your sourdough starter is the key ingredient that determines whether your croissants will rise properly and develop their signature airy, honeycomb-like texture.
👉 How to Ensure Your Starter Is Ready:
- Use a mature and well-fed starter that has been refreshed 4-6 hours before use.
- The starter should double or triple in size after feeding, with lots of bubbles.
- If your starter is weak, feed it for 2-3 days before using it in the dough.
💡 Pro Tip: To test if your starter is strong enough, perform the float test—drop a spoonful of the starter into a cup of water. If it floats, it’s ready; if it sinks, it needs more feeding.
2. Maintain the Right Butter-to-Dough Ratio for Perfect Lamination
The butter-to-dough ratio is critical for creating flaky layers. Too much butter can cause the dough to become greasy, while too little butter results in dry, stiff croissants.
👉 Best Butter-to-Dough Ratio:
- Use 250g of high-fat butter for every 500g of flour.
- Choose European-style butter (82%+ fat content) for a rich, creamy texture.
💡 Pro Tip: Always keep the butter and dough at the same temperature to prevent the butter from breaking or melting into the dough. If the butter cracks, it’s too cold; if it oozes out, it’s too warm.
3. Allow Slow Fermentation for Better Texture and Flavor
Sourdough croissants develop their unique flavor and texture through long, slow fermentation. Rushing the process will result in dense, flavorless croissants.
👉 How to Maximize Fermentation:
- Perform bulk fermentation overnight (8-12 hours) in the fridge to enhance flavor.
- Let the shaped croissants proof overnight (8-12 hours) at 4-6°C (39-43°F) to develop a light and airy structure.
- Avoid over-proofing at room temperature, as it weakens the dough and collapses layers.
💡 Pro Tip: If your kitchen is warm, proof croissants in the fridge for longer to slow down fermentation and maintain butter integrity.
Common Mistakes & How to Fix Them
Even experienced bakers encounter issues when making sourdough croissants. Below are some of the most common mistakes and how to fix them.
1. Dough Too Tough? Let It Rest Longer
Problem: If your dough feels stiff, hard, or difficult to roll out, it may be due to over-kneading or insufficient resting time.
👉 Why This Happens:
- Overdeveloped gluten makes the dough tight and unworkable.
- Cold dough can be too firm right out of the fridge.
✅ Solution:
- Let the dough rest at room temperature for 10-15 minutes before rolling.
- Avoid over-kneading—stop once the dough becomes smooth and elastic.
- If the dough resists rolling, chill it for 20 minutes before trying again.
💡 Pro Tip: Do not force the dough—if it resists rolling, let it rest longer to relax the gluten.
2. Butter Leaking? Keep Everything Cold While Laminating
Problem: If butter leaks out during rolling or baking, your layers will fuse together, leading to dense croissants.
👉 Why This Happens:
- The butter was too warm, causing it to mix into the dough.
- The kitchen was too hot, melting the butter before baking.
- The dough was rolled too aggressively, damaging the layers.
✅ Solution:
- Chill the dough and butter between each fold (at least 30 minutes).
- Keep your workspace cool (below 20°C / 68°F)—if it’s too warm, freeze the dough for 10 minutes before rolling.
- Avoid pressing too hard with the rolling pin—gentle pressure preserves the layers.
💡 Pro Tip: If butter starts melting, freeze the dough for 10 minutes to prevent layer collapse.
3. Croissants Not Rising? Starter Might Be Weak—Feed It Well Before Use
Problem: Your croissants look flat, dense, and lack volume after baking.
👉 Why This Happens:
- Your sourdough starter was too weak to create proper fermentation.
- The dough didn’t proof long enough for the gluten to develop properly.
- The butter layers were crushed, preventing proper oven spring.
✅ Solution:
- Feed your starter twice a day for 2-3 days before baking to ensure it’s strong.
- Extend proofing time—sourdough takes longer to rise than commercial yeast dough.
- Make sure croissants are properly laminated—if layers get crushed, they won’t expand.
💡 Pro Tip: If your croissants aren’t rising enough, try proofing them in a slightly warmer environment (22-24°C / 72-75°F) for 1-2 hours before baking.
