Best Tips for Success
Kneading By Hand vs. Mixer
If you don’t have a stand mixer, don’t stress. After mixing, knead the dough on a lightly floured surface for 8-10 minutes until it becomes smooth and elastic. Don’t worry about over-kneading—it’s nearly impossible to do by hand!
Why Pan Size Matters
For a high, fluffy loaf, use an 8.5×4-inch loaf pan instead of the standard 9×5. The smaller pan forces the dough to rise taller.
Adjusting for a Vegan Version
Swap the butter for a plant-based alternative. Just keep in mind that some vegan butters have added salt, so adjust accordingly.
Temperature Controls Everything
Fermentation time depends on temperature. A warm kitchen speeds up rising, while a chilly space slows things down. Need a boost? Place the dough in a proofing box or near a warm oven.
How to Make Sourdough Sandwich Bread
Step 1: Mixing the Dough
Start by weighing your ingredients for accuracy. In a stand mixer fitted with the paddle attachment, combine flour, butter, sugar, and salt. Mix until the butter resembles fine crumbs. Add the sourdough starter recipe and warm water, mixing until combined. Cover and let the dough rest for 30 minutes—this relaxes the gluten.
Step 2: Kneading the Dough
Switch to a dough hook and knead for about 6-8 minutes until the dough is soft, stretchy, and no longer sticky. If kneading by hand, work the dough for 8-10 minutes. If it’s too sticky, dust with a little flour.
Step 3: Bulk Rise (First Fermentation)
Cover the bowl with plastic wrap or a damp towel. Let the dough rise overnight at room temperature (about 10-12 hours). You’ll know it’s ready when it doubles in size.
Step 4: Shaping the Dough
In the morning, grease a loaf pan with butter. Turn the dough onto a lightly floured surface, gently flattening it to release air bubbles. Roll it into a log shape, tucking the edges underneath. Transfer to the prepared pan.
Step 5: Second Rise (Final Proofing)
Cover and let the dough rise again. It’s ready for baking when the center is about 1 inch above the rim of the pan. Be patient—this step takes time, especially in cooler temperatures.

Step 6: Preheating & Baking
Preheat your oven to 375°F. For extra oven spring, start at 500°F, then lower to 375°F once the bread goes in. Bake for 45-50 minutes until golden brown.
Step 7: Cooling & Slicing
Let the bread cool for at least an hour before slicing. Cutting too soon will make the texture gummy. Use a serrated knife for best results.
Additional Notes & Storage Tips
- If you bake often, double the recipe and freeze a loaf. Wrap tightly in plastic wrap and freeze for up to 3 months.
- Slicing bread unevenly? Try a bread slicer for perfectly uniform slices.
- Store at room temperature in an airtight container for up to 5 days.
Sourdough Sandwich Bread Variations
Whole Wheat Variation
Replace 20% of the all-purpose flour with whole wheat flour. If the dough feels dry, add extra water 1 teaspoon at a time.
Bread Flour Swap
Using bread flour? It absorbs more liquid, so you may need to increase hydration slightly. King Arthur Bread Flour tends to be extra thirsty, while Gold Medal requires fewer adjustments.
Sourdough Cinnamon-Raisin Bread
