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,

I noticed on the amount of flour it says 2 1/2 c but by weight you say 12.5 oz or 350 g. Shouldn’t it be 20 oz or 600 g?
A cup of flour weighs 5 oz (using the “dip & sweep” method).
I made the recipe again this morning and it was a huge success!! My first loaf I tried was too dense and undercooked. I made a few tweaks to my technique and husband said it’s his favorite bread I’ve ever made. Will make again!! Question: how does this double in a standard size kitchen aid mixer?
I wouldn’t do a double batch in a kitchen aid mixer. It would be really heavy. I say that having stripped gears on my kitchen aid more than once.
How do I get the loaf to be less dense? My loaf came out pretty thick/dense. Suggestions?
There are many reasons the loaf could be dense. First question that comes to mind is if the dough was fully proofed before baking. Second question would be if the dough was overproofed and deflated.
I used less flour
I loved the smell and texture of the dough as it was doing its bulk ferment. I finished with that around 2pm, put it in the fridge with a tight lid overnight. Took it out first thing in the morning and it was super dense! I slightly kneaded it, shaped it, and put it into the pan. After a couple of hours (I usually let my dough sit in my oven turned off but with the light on), checked with the finger poke and it needed reshaping. So reshaped and did finger poke occasionally until it passed the test. Even though it passed the test, it had not doubled so I was not sure what I should do. So I baked it. After about 35min, I took its temp and got 200°, but when I got to thr middle it was so gummy and doughy! The first couple of slices, while slightly chewy were still very tasty! I tried to stick it back in the oven but it only made it worse. Do you think keeping it tightly sealed overnight was the problem? My boule recipes I just cover with towel overnight. Or could do you think I messed it up some other way??
Hmmm, I’ve never had this dough behave this way. I’m surprised it was dense after the night in the fridge. My dough is usually super-airy after the night. Was your starter nice and active when you made the dough? When you reshaped the dough the first time had the loaf risen nicely?
I had fed my starter the night before I made the dough and it passed the float test when I mixed it, but it was still passed the 4-6hr peak. Could have been that!! I did not feel like it really rose very well after I put it in the pan. It rose while it was baking though but deflated after it cooled. I’ll definitely try again. I’m in South Louisiana so not sure if our climate has anything to do with how mine turned out.
I usually feed my started in the evening and let it sit overnight but and then bake the next day but I hadn’t fed it in a while so I I fed my starter yesterday morning And put it in the fridge last night. Can I bake bread today?
I have had success if I’ve fed the starter and just refrigerated it for a day. I find that it’s still quite active when I take it out of the fridge. Of course, as with everything sourdough, you’ll have to listen to what your starter is telling you. If you take it out of the fridge and it looks airy and active go ahead. If it looks like it’s past it’s prime feed it again.
