There is nothing quite like a loaf of homemade sourdough sandwich bread. This soft and tender version combines the gentle tang of an active sourdough starter with warm milk, butter, and a touch of honey or sugar for a beautifully soft crumb. It is easy enough for everyday baking and versatile enough for everything from breakfast toast to hearty sandwiches.
Unlike rustic sourdough loaves with a thick, chewy crust, this sandwich-style bread is designed to be soft, sliceable, and practical. Baking it in a loaf pan also makes shaping much simpler, making this an excellent recipe for both experienced sourdough bakers and beginners.
Why You’ll Love This Recipe
This homemade sourdough sandwich bread has a wonderfully tender texture and mild sourdough flavor. The milk and butter help create a soft crumb, while honey or sugar adds a subtle sweetness.
It is also incredibly versatile. Use fresh slices for sandwiches, toast them with butter, make grilled cheese, or turn day-old bread into French toast.
The dough does require time for fermentation and proofing, but most of that time is hands-off. Once you understand how the dough should look and feel, the process becomes much easier.
Ingredients
- 100 g active sourdough starter
- 250 g warm milk
- 100 g warm water
- 500 g bread flour
- 30 g honey or sugar
- 10 g fine sea salt
- 40 g unsalted butter, softened
- 1 tablespoon olive oil, optional
The original recipe uses these quantities for one loaf.
Prepare the Dough
Begin by adding the active sourdough starter to a large mixing bowl. Pour in the warm milk and warm water, then stir until the starter is well dispersed.
Add the bread flour, honey or sugar, and salt. Mix everything together until a rough dough forms and there are no obvious areas of dry flour.
The dough does not need to look smooth at this stage. Cover the bowl and let it rest for about 30 minutes. This short rest gives the flour time to absorb the liquid and makes the dough easier to handle.
Add the Butter
After the dough has rested, add the softened butter gradually.
Work the butter into the dough with your hands, folding and squeezing gently until it is completely incorporated. If you are using olive oil, add it along with the butter.
At first, the dough may feel sticky and soft. Do not immediately add extra flour. As the butter becomes incorporated and the dough develops strength, its texture should become smoother and more manageable.
The butter is an important part of this recipe because it helps create the soft, tender texture associated with sandwich bread.
Stretch and Fold
Cover the dough and let it rest for another 30 minutes.
Now begin the stretch-and-fold process. With slightly wet hands, grab one side of the dough and gently stretch it upward. Fold that section over the center.
Turn the bowl and repeat the process several times until you have worked around the dough.
Allow the dough to rest for another 30 minutes, then repeat the stretch-and-fold process.
Complete approximately 3–4 rounds in total. By the final round, the dough should feel noticeably stronger, smoother, and more elastic.
This gentle strengthening method is much easier than traditional intensive kneading and works beautifully with sourdough dough.
Bulk Fermentation
Once your stretch-and-folds are complete, cover the bowl and let the dough ferment at room temperature.
The exact timing will depend on the temperature of your kitchen and how active your starter is. A warmer environment will speed fermentation, while a cooler kitchen may require additional time.
Look for the dough to become puffy, airy, and noticeably larger. A rise of approximately 50–75% is a useful guide.
The dough does not have to completely double in size. Waiting for a full doubling can sometimes result in over-fermentation, especially in a warm kitchen.
Shape the Loaf
When bulk fermentation is complete, lightly flour your work surface.
Gently turn the dough onto the surface, taking care not to completely deflate it.
Shape it into a rough rectangle, then fold the top third toward the center. Fold the bottom third upward.
Roll the dough into a tight log, creating enough surface tension to help the loaf maintain its structure.
Pinch the seam closed.
This simple shaping method produces a neat loaf that will rise beautifully in the pan.
Place in the Loaf Pan
Grease a 9 × 5-inch loaf pan thoroughly with butter or oil.
Place the shaped dough into the pan with the seam underneath.
Cover the pan loosely with plastic wrap or a clean kitchen towel.
The dough is now ready for its final proof.
Final Proof
Allow the dough to proof at room temperature for approximately 2–4 hours.
The timing can vary considerably depending on your kitchen temperature and the activity of your sourdough starter.
Rather than relying only on the clock, watch the dough.
It should rise noticeably and become soft, airy, and puffy. Gently press the surface with your fingertip. If the indentation slowly springs back, the dough is generally ready to bake.
If the dough immediately springs back, give it more time.
Bake the Bread
Preheat your oven to 375°F (190°C).
For a beautifully soft crust, lightly brush the surface of the dough with milk before placing it in the oven.
Bake for approximately 35–40 minutes, or until the loaf is deeply golden and the internal temperature reaches approximately 190–200°F (88–93°C).
If the top begins browning too quickly, loosely cover the loaf with aluminum foil during the final 10–15 minutes of baking.
Cool the Loaf
Remove the bread from the pan as soon as it comes out of the oven.
Place it on a wire rack and, while it is still warm, brush the top lightly with melted butter. This adds flavor and helps keep the crust soft.
Allow the loaf to cool for at least 1 hour before slicing.
It can be tempting to cut into warm homemade bread immediately, but waiting allows the crumb to finish setting. Slicing too soon can compress the soft interior and make the bread seem gummy.
Tips for the Softest Sourdough Sandwich Bread
Use an Active Starter
For reliable fermentation, use a sourdough starter that is bubbly and active. A strong starter will help the dough rise properly and develop a pleasant fermented flavor.
Don’t Add Too Much Flour
The dough should remain soft and slightly tacky. Adding a large amount of extra flour can make the finished bread heavy and dry.
If the dough sticks to your hands, try using slightly wet hands instead of immediately reaching for more flour.
Pay Attention to Temperature
Fermentation is strongly affected by temperature.
A warm kitchen can significantly shorten the fermentation process, while a cooler environment may require more time.
Watch the dough rather than following the clock rigidly.
Use the Correct Pan Size
A 9 × 5-inch loaf pan provides a good shape for this amount of dough.
The correct pan helps the bread rise upward rather than spreading outward.
Don’t Slice Too Early
Letting the bread cool completely gives the crumb time to settle and makes slicing much easier.
Serving Ideas
There are so many ways to enjoy this soft sourdough sandwich bread.
Use it for classic chicken or turkey sandwiches, grilled cheese, egg sandwiches, or peanut butter and jelly.
For breakfast, toast a slice and top it with butter and honey, avocado, eggs, or your favorite jam.
You can also use this bread for French toast. Its tender crumb absorbs the egg mixture beautifully while remaining sturdy enough to cook without falling apart.
For a simple snack, toast a slice and spread it with butter while it is still warm.
Storage
Once the loaf has cooled completely, place it in an airtight bread bag or container.
At room temperature, it should remain enjoyable for approximately 3–4 days.
For longer storage, slice the bread before freezing. Place the slices in a freezer-safe bag and freeze for up to approximately 3 months.
One of the easiest things about freezing sliced bread is that individual slices can be taken directly from the freezer and placed into a toaster whenever needed.
Make It Extra Soft
The combination of milk, butter, and honey or sugar is what gives this loaf its particularly tender texture.
For an especially soft crust, brush the freshly baked loaf with a small amount of melted butter.
You can also avoid leaving the loaf uncovered for a long time after cooling. Proper storage helps prevent the crust from becoming unnecessarily dry.
