Why this is the best Sourdough Sandwich Bread
White Sandwich Bread doesn’t have to have the lackluster taste and squishy texture of a certain “wonderous” bread that many of us ate growing up. This sourdough sandwich bread has deep flavor, a beautiful texture and a soft crust.
Milk, butter and a whisper of sugar create a perfectly soft white bread that is ideal for making a great PB&J or BLT.
Although this recipe takes a good 8-12 hours from start to finish, the vast majority of the time is hands off.
To make this recipe even more convenient, you can let the dough rise over night. A long rise in the refrigerator does only good things for the bread.
If you don’t already have one, I can show you how to make a sourdough starter and how to feed a sourdough starter.
Ingredients

Ingredient Notes
- Sourdough Starter – This recipe was developed using 100% hydration starter. You will need to adjust the liquid or flour in the recipe if you’re starter isn’t at 100% hydration.
- All Purpose Flour – Medium protein AP flour makes a bread with a soft crumb yet develops enough gluten so the bread rises high in the oven.
- Milk – Scalding denatures (breaks down) proteins in the milk which can interfere with gluten development.
- Butter – A little fat softens the crumb of the bread.
- Salt – For flavor.
- Sugar – Enhances browning and make the crumb soft and slightly sweet.
How to make Sourdough Sandwich Bread with a soft crust

- Mix the dough and set it aside for the initial fermentation.
- With each hour of fermentation the dough will rise higher, become more active and more elastic.
- After the initial fermentation you can continue on to shape and bake the loaf, or you can refrigerate the dough overnight and continue the next day. A long, cool rest in the refrigerator enhances the flavor and texture of the dough.

- Turn the dough out onto a lightly floured surface.
- Without kneading out the air, gently form the dough into a rectangle.
- Roll the rectangle into a log and set into a lightly greased loaf pan.

- Cover the pan and set the loaf aside to rise.
- The dough will expand to almost fill the pan.
- Slash the top of the loaf to promote even rising in the oven.

- Brush the loaf with egg wash and bake until the interior temperature is 200F.
- Cool the loaf completely before cutting.
A timeline for making Sourdough Sandwich Bread:
- If your starter needs feeding, do that the night before or early in the morning of the day you want to make the dough.
- Mix the dough in the afternoon, allow it to ferment for 3-4 hours then refrigerate the dough before going to bed.
- Take the dough out of the refrigerator first thing in the morning, shape the loaf and set it into the pan.
- To warm up the dough, turn on the oven just until it’s barely warm. Turn off the oven and set the pan with the cool dough in the oven. Remove the pan once the dough is back to room temperature. You can skip this step, but it does speed up the rising time.
- Leave the loaf to rise for 1 1/2- 2 hours, or as long as is needed to almost double in size.
- To make and bake the dough in the same day, feed your starter the evening before so it’s active by morning. Start the dough early in the morning and it should be ready to bake by late afternoon or early evening.
Storage
Sourdough Sandwich bread will keep at room temperature for 2-3 days. The bread (sliced or whole) can be frozen for up to a month.

Sourdough Sandwich Bread Recipe
Ingredients
- 8 oz whole milk (1 cup)
- 1 oz unsalted butter
- 8 oz active sourdough starter (1 cup, 100% hydration)
- ½ oz granulated sugar (1 tablespoon)
- 1 ½ teaspoons salt
- 12 ½ oz all purpose flour (2 ½ cups, see note)
- 1 large egg (for egg wash)
Instructions
- Warm 8 oz whole milk in the microwave to until scalding hot (just before it comes to a boil.) Stir 1 oz unsalted butter into the warm milk to melt. Set the milk aside to cool until it's slightly warmer than body temp.
- In a mixer bowl, combine the warm milk with 8 oz active sourdough starter, ½ oz granulated sugar and 1 ½ teaspoons salt and stir to combine. Add 1 ½ cups of the flour and stir until the batter looks like thick pancake batter. If using a stand mixer, change to the dough hook.
- With the mixer running, slowly add the remaining flour until the dough gathers on the hook and clears the sides of the bowl. Knead for 5 minutes. If mixing by hand, stir in as much flour as you can then turn the dough out onto a floured surface and knead in the remaining flour.
- Remove the dough from the bowl onto a lightly floured surface. The dough should be soft and slightly sticky. Knead to form a smooth ball. If the dough is very sticky sprinkle a little more flour as you knead.
- Place the dough in an oiled bowl, turning once to coat the dough. Cover the bowl and set it aside at room temperature.
- After 60 minutes uncover the bowl, lift one side of the dough and fold it into the middle of the dough. Repeat with the other three sides of the dough then flip the dough over. You're basically turning the dough inside-out to redistribute the yeast and strengthen the gluten. Cover the bowl and after 60 minutes repeat the procedure.
- Cover the bowl and after 60 minutes fold the dough one more time. By now the dough should be lively, elastic and airy. If the dough is still sluggish give it another hour or two at room temperature. If you want to finish making the bread in the morning return the dough to the bowl, cover tightly and refrigerate overnight. The next morning continue with shaping. Otherwise continue shaping the loaf on the same day.
- Grease a 9"x 5" loaf pan with a very light film of vegetable oil.
- Turn the dough out onto a floured surface and without kneading out the air, gently push the dough to a 9" rectangle. Tightly roll the dough to form a log.
- Set the dough into the pan and cover with a damp kitchen towel or oiled plastic wrap. Set in a warm place and rise until the dough is doubled in size, about 1-1½hours.
- Preheat the oven to 350 °F. Use a sharp knife or razor to cut a 1/2" deep slash down the center of the loaf. Brush the loaf with egg wash.
- Bake about 30-35 minutes until golden brown and and a toothpick inserted in the center comes out clean. The interior temp should be 200 °F.
- Cool in the pan for 5 minutes before turning out onto a cooling rack. Finish cooling to room temperature before slicing,

My first time baking a sandwich loaf. But had a smaller loaf pan & needed to estimate how much to fill in. Resulted in a smaller loaf and a small braided one. . It was a great success.in texture and flavor.
I .m baking this loaf today. Does the load risen when baking?
Are you asking if the loaf rises while baking? Yes, it does. That’s why you slash it down the middle. It give the dough a place to expand as it rises.
Hello! I’ve been searching far and wide to find a good sandwich bread recipe! The thing that usually hits a snag for me is dairy…is there a particular science behind dairy in bread? Does it need the higher fat content in particular by using whole milk as well as the butter? Just wondering if plant based would be an equal substitute? Like if I were to use a nut based half and half versus a milk? Does it matter? I’m thinking plant based butter would be a sufficient substitute for flavor. Thoughts?
Thanks so much! Looking forward to trying a lot of your recipes because I love your clear and concise steps!
Hi Lyndsay. In this recipe, yes, the butter and milk are providing fat for tenderizing the crumb of the bread for that quintessential soft sandwich bread character. If you use a plant based product that has fat content I think you’ll get a pretty good result. Almond or coconut milk and maybe vegetable shortening would work well, I think.
I’ve read through the comments and my question wasn’t answered, at least not that I could see. If I want to make the bread all in one day, at what point do I let it set and rise? Between 5 & 6 there seems to be only 30 minutes. Then between 6 & 7 there is only 80 minutes, unless it is still sluggish. From there if one isn’t finishing it in the morning there is no long rise time. It says to simply continue shaping the loaf on the same day. I’m sorry if I’m confused, but there just seems to be something missing in the instructions. After shaping it is left to rise for 1 – 1.5 hours. And then backed for 30-35 minutes. That gives at best a total of 3.5 hours. Thank you for your help.
At the end of step 7 instead of putting the dough in the refrigerator you go right on to shaping and rising the loaf. From there follow the steps as noted. The length of time for the final rise may be a bit shorter since the dough is not cold. But with sourdough, the times are always just broad estimates that can vary based on the temp of the dough, the ambient temp and the activity of your starter.
Thanks so much for this recipe, I tried it today and love the results.
Just a couple of things I’d like to check with you. I’m in England so I wasn’t sure what type of flour to use. I would normally make sourdough bread with bread flour but Your recipe says to use ‘all purpose’. I made two loaves today, one using British ‘plain’ flour (about 10% protein) and the other using some ‘all purpose’ flour I managed to find (only 3% protein.) They both worked well but I think the one using plain flour (9%) gave a better result as the other was very soft (still delicious) I had to add an extra 50g of flour to both loaves though as it was far too sticky. My starter is 100% so I’m not sure why that was, any idea? Also what protein is the flour you use? And would it work with bread flour (about 12.5% protein)? Finally I used fresh skimmed milk (fat free) and that seemed fine. I’ll certainly be making many more.
American all purpose flour is about 11.7% protein and bread flour is 12.7%. So I think maybe a mix of “plain” flour and “bread flour” would be a good approximation of all purpose flour. Plain flour at 9% is closer to American cake flour. Skim milk is fine.
