The Ultimate Sourdough Sandwich Bread Recipe
Making the perfect sourdough sandwich bread from scratch is a rewarding experience that yields a soft, flavorful loaf ideal for your favorite sandwiches. This easy-to-follow recipe is great for beginners and experts alike.

What Is Sourdough Sandwich Bread?
Sourdough sandwich bread is a traditional, naturally leavened bread made with a sourdough starter. Unlike yeast-based bread, sourdough uses wild yeast and bacteria to rise, providing a unique tangy flavor and a chewy texture. This bread is ideal for sandwiches due to its soft crumb and slightly firm crust.

How To Make Sourdough Sandwich Bread
This step-by-step guide ensures you get the best sourdough sandwich bread every time.
Mix the Dough

Start by mixing your ingredients: sourdough starter, flour, water, and salt. Use a stand mixer or mix by hand until you have a sticky dough. Let the dough rest for about 30 minutes.
Bulk Rise (Overnight)

After the dough is mixed, let it rise in a warm place for about 8 hours, or overnight. This is when the dough will ferment and develop its flavor.
Shape the Dough

After the bulk rise, turn the dough out onto a floured surface. Gently shape it into a loaf by folding the dough’s edges towards the center and rolling it into a tight log shape.
Second Rise

Place the shaped dough into a loaf pan, cover, and let it rise for another 3-4 hours, or until it’s doubled in size.
Bake the Bread
Preheat the oven to 375°F (190°C). Bake the dough for about 35-40 minutes or until golden brown. Allow it to cool before slicing.

Sourdough Sandwich Bread Variations
Soft Sourdough Sandwich Bread
For an extra soft sandwich loaf, use a higher hydration dough (more water) and consider adding a tablespoon of honey or olive oil to the dough for a tender crumb.

Sourdough Discard Sandwich Bread
If you have leftover sourdough starter, use it in this recipe to avoid waste. Just replace a portion of the flour and water with sourdough discard. This adds even more flavor to your bread.
Sourdough Rye Sandwich Bread
For a twist on the traditional recipe, use a combination of all-purpose flour and rye flour. Rye adds a distinctive, slightly nutty flavor and a denser texture, perfect for hearty sandwiches.

Common Sourdough Baking Mistakes to Avoid
- Using an Inactive Starter: Always ensure your starter is bubbly and active before using it.
- Skipping the Rest Periods: The dough needs time to rise and develop its flavors. Don’t rush the process!
- Too Much Flour: Avoid adding too much flour when shaping the dough, as it can make the bread dense.
How to Achieve the Perfect Sourdough Crust
Achieving the perfect sourdough crust involves using a high temperature at the beginning of baking and using steam in the oven to create a crispy, golden crust. For even better results, you can use a Dutch oven to bake the bread, which traps steam and helps develop a beautiful crust.
Why Choose Sourdough Bread?
- Health Benefits: Sourdough is naturally fermented, which makes it easier to digest. It also contains beneficial probiotics and has a lower glycemic index compared to regular bread.
- Flavor: The wild fermentation process imparts a slightly tangy, complex flavor that makes every bite delicious.
- Better Texture: Sourdough sandwich bread has a perfect balance of soft inside with a slightly chewy crust, making it ideal for holding up to fillings.
The Science Behind Sourdough Bread
The sourdough fermentation process involves wild yeast and lactic acid bacteria working together. These microorganisms ferment the flour and water, producing gas that causes the dough to rise. The acidity created during this fermentation process not only contributes to the bread’s unique flavor but also makes it more digestible.
Helpful Tips for the Perfect Sandwich Loaf
- Hydration: For a softer loaf, increase the water content slightly.
- Fermentation Time: Longer fermentation results in better flavor, but don’t rush the process.
- Storage: Store your bread in a paper bag or wrapped in a clean cloth for up to 5 days. For longer storage, freeze slices for easy sandwiches later.

- 1 cup sourdough starter (active and bubbly)
- 3 1/2 cups all-purpose flour
- 1 1/4 cups water
- 1 1/2 tsp salt

Instructions
- Mix the Dough: Combine the sourdough starter, water, flour, and salt in a large mixing bowl. Stir until a sticky dough forms. If using, add honey or olive oil at this stage.
- Bulk Rise (Overnight): Cover the dough and let it rest at room temperature for about 8 hours or overnight. The dough should rise and show signs of fermentation.
- Shape the Dough: After the first rise, turn the dough out onto a floured surface. Shape it into a loaf by folding the edges towards the center and rolling it tightly.
- Second Rise: Place the dough into a loaf pan. Cover and let it rise for 3-4 hours or until doubled in size.
- Bake the Bread: Preheat the oven to 375°F (190°C). Bake the bread for 35-40 minutes, or until the crust is golden and the loaf sounds hollow when tapped on the bottom.
- Cool and Slice: Let the bread cool completely before slicing.
Notes
- Storage: Store the bread in a paper bag or wrapped in a clean kitchen towel for up to 5 days. For longer storage, freeze slices and toast when needed.
- Pro Tip: For an even softer loaf, add a tablespoon of honey or olive oil to the dough. The higher hydration will result in a tender crumb.
