This Homemade Sourdough Sandwich Bread is soft, fluffy, tender, and perfect for everyday baking. Made with an active sourdough starter, milk, butter, and simple pantry ingredients, it has a wonderfully soft crumb with a gentle sourdough tang.
Unlike a crusty artisan sourdough loaf, this sandwich bread is baked in a loaf pan for neat, even slices that are perfect for sandwiches and toast. Milk adds richness and tenderness, while butter gives the bread a soft texture and delicious flavor.
The dough does require time to rise, but the hands-on work is simple. Once you get familiar with the fermentation process, this recipe can easily become your go-to homemade loaf.

Ingredients
- 500 g bread flour or all-purpose flour

- 250 ml lukewarm milk or water
- 30 g unsalted butter, softened
- 25 g granulated sugar, optional
- 10 g salt
How to Make Sourdough Sandwich Bread
1. Make the Dough
Add the active sourdough starter, lukewarm milk, and sugar to a large mixing bowl. Stir until the starter is mostly incorporated into the liquid.
Add the flour and mix until a rough dough forms.
Add the salt and softened butter. Knead the dough by hand or with a stand mixer for about 8–10 minutes.
The finished dough should feel smooth, soft, and slightly tacky. It shouldn’t be excessively sticky.
2. Let the Dough Rise
Place the dough in a lightly greased bowl and cover it with a clean kitchen towel or plastic wrap.
Let the dough rise in a warm place for approximately 4–6 hours.
During the first few hours, perform 2–3 gentle stretch-and-folds. To do this, stretch one side of the dough upward and fold it toward the center. Turn the bowl and repeat around the dough.
By the end of the bulk fermentation, the dough should look softer, smoother, and noticeably puffy.
Keep in mind that sourdough fermentation is affected by room temperature and starter activity, so the exact timing can vary.
3. Shape the Loaf
Lightly flour your work surface and gently transfer the dough onto it.
Shape or roll the dough into a rectangle.
Starting from one short side, roll the dough tightly into a loaf. Try to keep the roll even from end to end so the bread rises evenly.
Place the shaped dough into a greased loaf pan with the seam facing down.
4. Proof the Loaf
Cover the loaf pan and let the dough rise for another 2–4 hours.
Rather than relying only on the clock, watch the dough carefully. It should become light and puffy and rise close to the top of the loaf pan.
If your kitchen is cool, the second rise may take longer.
5. Bake the Bread
Preheat the oven to 350°F (180°C).
Place the loaf in the oven and bake for approximately 30–35 minutes, or until the top is golden brown and the loaf feels firm.
If the top begins to brown too quickly, loosely cover it with aluminum foil during the final part of baking.
6. Cool Completely
Remove the bread from the oven and carefully take it out of the loaf pan.
Transfer it to a wire rack and allow it to cool completely before slicing.
Although it can be tempting to cut into freshly baked bread, slicing while it’s still hot can make the crumb gummy and cause the slices to lose their shape.
Once completely cool, use a sharp bread knife to cut the loaf into even slices.
Helpful Tips for the Best Sourdough Sandwich Bread
Use an Active Starter
Your sourdough starter should be recently fed, bubbly, and active before you begin. An inactive starter may not provide enough leavening power, which can lead to a dense loaf.
Don’t Add Too Much Extra Flour
The dough should be soft and slightly tacky. Resist the temptation to add large amounts of flour while kneading, as this can make the finished bread heavier and drier.
Milk Makes the Bread Softer
Milk contributes to a tender, soft crumb and gives the loaf a slightly richer flavor. You can replace it with water if preferred, but the finished bread may be a little less rich.
Butter Adds Tenderness
Softened butter helps create a tender texture and adds flavor. You can omit it if necessary, although the loaf may be slightly less soft.
Watch the Dough, Not Just the Clock
Sourdough fermentation depends on several factors, including room temperature and starter activity. A warm kitchen will generally speed up fermentation, while a cooler kitchen will slow it down.
Look for a dough that becomes noticeably puffy and airy before moving on to shaping or baking.
Overnight Proofing Option
If you’d like to develop more flavor or make the process easier to fit into your schedule, you can use an overnight proof.
After shaping the dough and placing it in the loaf pan, cover it well and refrigerate overnight.
The next day, take the loaf out of the refrigerator and let it sit at room temperature until it becomes puffy and rises close to the top of the pan.
Once properly proofed, bake according to the recipe instructions.
How to Serve Sourdough Sandwich Bread
There are countless ways to enjoy this soft homemade bread.
Toast slices and spread them with butter, jam, honey, or your favorite nut butter. Use it to make chicken, tuna, turkey, or cheese sandwiches.
It’s also excellent for:
- Grilled cheese
- Breakfast sandwiches
- Egg sandwiches
- Avocado toast
- Peanut butter toast
- French toast
- Simple buttered toast
For an easy breakfast, toast a couple of slices and top them with eggs, avocado, or your favorite spread.
How to Store Sourdough Sandwich Bread
Once the loaf has cooled completely, store it in an airtight bread bag or container at room temperature.
For the best texture, avoid slicing the entire loaf until you’re ready to use it. Keeping the loaf whole helps it retain moisture.
For longer storage, slice the bread and freeze the slices in a freezer-safe bag or container. Place small pieces of parchment paper between the slices so you can easily remove only what you need.
Frequently Asked Questions
Can I use all-purpose flour?
Yes. Bread flour gives the loaf a slightly stronger and chewier structure, but all-purpose flour works well too and can produce a soft sandwich loaf.
Can I use water instead of milk?
Yes. Water can be used in place of milk. However, milk gives the bread a softer, more tender, and slightly richer crumb.
Why is my sourdough sandwich bread dense?
A dense loaf can be caused by an inactive starter, insufficient fermentation, under-proofing, or adding too much flour to the dough. Make sure your starter is active and give the dough enough time to become noticeably puffy.
Can I skip the sugar?
Yes. The sugar is optional. It adds a little sweetness and contributes to the soft, tender texture of the sandwich bread.
Can I make this bread overnight?
Yes. After shaping the loaf, cover the pan and refrigerate it overnight. The following day, let the dough continue proofing at room temperature until it becomes puffy and approaches the top of the pan before baking.
How do I get evenly sliced sandwich bread?
Let the loaf cool completely before slicing and use a sharp serrated bread knife. Cutting the bread while warm can compress the soft crumb.
