Classic Sourdough Bread: How to Make the Perfect Loaf at Home

Jump to Recipe

Introduction

Classic Sourdough bread is loved for its rich flavor, crispy crust, and soft crumb. More people are baking it at home because it’s healthier and full of natural goodness. Unlike store-bought bread, sourdough uses wild yeast instead of commercial yeast. This slow fermentation makes it easier to digest and better for gut health.

Homemade sourdough has no preservatives or artificial additives. It also tastes amazing with its deep, slightly tangy flavor. Plus, baking your own loaf is a fun and rewarding experience.

In this guide, you’ll learn how to make classic sourdough bread from scratch. We’ll cover everything from creating a strong sourdough starter to baking the perfect golden-brown loaf. Whether you’re a beginner or an experienced baker, these tips will help you master the art of sourdough baking. Let’s get started!

What is Classic Sourdough Bread?

Sourdough bread is a naturally fermented bread made with just flour, water, and salt. It doesn’t use commercial yeast. Instead, wild yeast and bacteria from the environment help the dough rise. This slow fermentation process creates a deep, tangy flavor and a soft, airy crumb.

Why Use a Sourdough Starter?

A sourdough starter replaces commercial yeast. It’s a live culture of flour and water that ferments over time. The natural yeast gives the bread a unique taste and texture. It also makes it easier to digest because it breaks down gluten and phytic acid. A well-fed starter improves the rise, crumb, and flavor of your sourdough loaf.

Essential Ingredients for Sourdough Baking

You only need three ingredients:

  • Flour – Bread flour works best for a strong dough, but you can also use whole wheat or rye.
  • Water – Use filtered or spring water to avoid chlorine, which can weaken the starter.
  • Salt – Sea salt or kosher salt enhances the flavor and strengthens the dough structure.

Tools You Need to Make Sourdough at Home

The right tools make sourdough baking easier:

  • Banneton – A proofing basket that helps shape the dough.
  • Dutch Oven – Traps steam to create a crispy crust.
  • Bread Lame – A razor tool for scoring the dough before baking.

With the right ingredients and tools, you’re ready to bake a perfect loaf! Next, let’s create a strong sourdough starter.

How to Make a Strong Sourdough Starter

What is a Sourdough Starter?

A sourdough starter is an active mixture of flour and water that naturally ferments over time. It captures wild yeast from the air and allows natural fermentation. This process creates levain, which helps bread rise without commercial yeast. A strong starter adds a deep, tangy flavor and improves texture.

Step-by-Step Process to Create a Starter

Making a sourdough starter takes patience. Follow these steps:

  1. Day 1 – Mix ½ cup of flour and ¼ cup of water in a jar. Stir well and cover loosely.
  2. Day 2-3 – Feed it daily by adding the same amount of flour and water. Mix well and leave it at room temperature to rest.
  3. Day 4-5 – Bubbles should appear. The starter should have a slightly tangy smell. Continue feeding daily.
  4. Day 6-7 – It should double in size a few hours after feeding. Now it’s ready to use!

Use unbleached flour and filtered water for the best results. Whole wheat or rye flour speeds up fermentation.

How to Know When Your Starter is Ready to Bake

A mature sourdough starter should be bubbly and rise after feeding. To test if it’s ready, do the float test. Drop a spoonful of starter into water. If it stays on the surface, it’s ready for baking. If it sinks, keep feeding for a few more days.

Troubleshooting Common Sourdough Starter Issues

  • Inactive starter? Keep it warm (70-75°F) and feed it regularly.
  • Too sour or weak? Discard half before feeding to refresh it.
  • Mold growing? Throw it out and start fresh. Use a clean jar and avoid contamination.

With a strong starter, you can bake amazing sourdough bread. Next, let’s mix and ferment the dough!

 Step-by-Step Guide to Making Classic Sourdough Bread

Mixing the Dough: Hydration and Autolyse

Start by mixing your flour, water, and sourdough starter. Let the dough rest for 30 to 45 minutes before adding salt. This step is called autolyse. It allows the flour to absorb water and develop gluten naturally. A well-hydrated dough creates a light, open crumb. Use a gentle folding technique instead of kneading to keep the structure strong.

Bulk Fermentation: Letting the Dough Rise

Once mixed, let the dough ferment for 4 to 6 hours at room temperature. Keep it in a covered bowl to prevent drying out. Stretch and fold the dough every 30 minutes to build strength. By the time fermentation is complete, the dough should expand to twice its original size. A warm spot (around 75°F) helps the yeast work faster.

Shaping and Final Proofing

Carefully form the dough into a circular or oval shape. Use a banneton (proofing basket) to support the shape. If the dough sticks, dust the basket with rice flour. Let it rise for another 1 to 2 hours at room temperature or refrigerate overnight for better flavor. Chilled dough is easier to handle and scores better before baking.

Scoring and Baking in a Dutch Oven

Before baking, score the dough with a bread lame to control how it expands in the oven. A deep slash creates a beautiful crust. Bake in a preheated Dutch oven at 475°F for the first 20 minutes with the lid on. This traps steam, giving the bread a crispy crust. Take off the lid and continue baking for 15-20 minutes until it turns golden brown.

Once done, let the bread cool completely before slicing. Next, let’s go over some pro tips to perfect your sourdough loaf!

How to Get an Open Crumb Structure

A light and airy crumb comes from proper hydration and gentle handling. Use at least 70% hydration (water to flour ratio) for a softer dough. Stretch and fold instead of kneading to keep the air pockets intact. Avoid overhandling, which can deflate the dough. A well-risen sourdough with strong fermentation creates the best open crumb.

Secrets to a Crispy Crust

A crispy crust needs the right baking temperature and steam. Bake at 475°F for the first 20 minutes with a lid on to trap moisture. Remove the lid for the final 15-20 minutes to create a deep golden color. Spraying water inside the oven or adding a tray of hot water can boost steam, giving the bread a better crust. Let the loaf cool fully before slicing to keep the crust crisp.

How to Avoid Dense or Gummy Sourdough Bread

Overproofing weakens the dough, while underbaking leaves the inside gummy. Watch for proper fermentation. The dough should double in size but still feel slightly firm. The poke test helps—press a finger into the dough. If it springs back slowly, it’s ready. Always bake long enough to let moisture escape. A fully baked loaf sounds hollow when tapped on the bottom.

Storing and Preserving Sourdough Bread

Keep sourdough fresh by wrapping it in a clean towel or storing it in a bread box. Steer clear of plastic bags, as they can soften the crust. For longer storage, freeze sliced sourdough in an airtight bag. Toast frozen slices directly for quick, fresh-tasting bread.

With these tips, you can bake perfect sourdough every time. Next, let’s troubleshoot common baking mistakes!

Why Your Sourdough Didn’t Rise Properly

If your sourdough loaf didn’t rise, the starter might be weak. Make sure it’s bubbly and passes the float test before using it. Fermentation time also matters. When the dough is too chilly, the yeast becomes less active. Keep it in a warm spot, around 75°F, to help it rise. If needed, let it ferment longer to build strength.

How to Prevent a Dense Loaf

A dense loaf often comes from improper gluten development. Folding works better than kneading for sourdough. Stretch and fold the dough every 30 minutes during bulk fermentation. This builds structure without deflating air pockets. Also, check hydration—drier dough is harder to work with, while higher hydration creates a better crumb.

Avoiding Overproofed or Underproofed Dough

Timing is key for sourdough bread. Overproofed dough becomes too weak, while underproofed dough stays dense. Use the poke test to check readiness. Lightly press the dough—if it springs back too quickly, it needs more time. If it stays indented, it’s overproofed. Stick to a schedule and adjust based on room temperature.

Ways to Enhance the Taste of Your Sourdough Bread.

The great flavor comes from proper fermentation. Long, slow fermentation enhances taste. Try a cold overnight proof in the fridge for a more complex flavor. The type of flour also matters. Whole wheat or rye flour adds depth, while bread flour keeps the texture light. Experiment with different flours to find your perfect balance.

With these fixes, you’ll bake better sourdough every time. Now, let’s wrap it up with a final summary!
