Best Sourdough Buttermilk Bread – Soft, Tangy & Homemade
If you have ever pulled a golden loaf from the oven and felt genuinely proud of yourself, you already know the magic of homemade bread. Now imagine that loaf with an extra layer of tangy depth, a pillowy soft crumb, and a crust that crackles just enough to make everyone in the house come running. That is exactly what Sourdough Buttermilk Bread delivers. The combination of a live sourdough starter and rich, acidic buttermilk creates a fermented bread that is complex in flavor yet surprisingly gentle on your schedule.
Whether you are a seasoned bread head who has been nurturing a starter for years or someone dipping their toes into buttermilk sourdough for the first time, this recipe meets you right where you are. It bakes up with that beautiful open crumb, a soft interior, and a tang that store-bought loaves simply cannot replicate. Once you taste it, plain sandwich bread will feel like a distant memory.
What Makes This Recipe Special
- Dual-acid magic: The combination of sourdough fermentation and buttermilk gives this loaf a nuanced tang that is deeper and more rounded than sourdough alone.
- Incredibly soft crumb: Buttermilk adds fat and acidity that tenderize the gluten strands, producing a soft bread recipe that stays moist for days.
- Forgiving timing: This dough is flexible. A long, slow cold ferment in the fridge means you can bake on your schedule, not the bread’s.
- Versatile and crowd-pleasing: From avocado toast to grilled cheese to a thick slab with salted butter, this loaf does it all beautifully.
Essential Ingredients
- Active sourdough starter (100g): Fed within 4 to 8 hours so it is bubbly and at peak activity. A lively starter is what drives the fermentation in this bread.
- Buttermilk (300ml): Full-fat buttermilk is ideal. Its acidity works in harmony with the starter and its fat content keeps the crumb soft.
- Bread flour (450g): Higher protein content builds the gluten structure needed for a good rise and chewy crumb. All-purpose flour works as a substitute but yields a slightly denser loaf.
- Whole wheat flour (50g): Just a small amount adds nuttiness, color, and extra nutrients without weighing the dough down.
- Fine sea salt (10g): Salt controls fermentation speed and enhances every other flavor in the loaf.
- Honey (1 tablespoon): A touch of sweetness balances the tang and helps with browning.
- Warm water (50ml): Used to loosen the dough to the right hydration level if needed.
Using quality tools and ingredients makes a real difference in bread baking, from the accuracy of your kitchen scale to the material of your Dutch oven.

Equipment
- Large mixing bowl
- Kitchen scale
- Dutch oven
- Banneton proofing basket or bowl with towel
- Bench scraper
- Bread lame or razor blade
- Parchment paper
- Wire cooling rack
Ingredients
- 100 g active sourdough starter fed 4 to 8 hours before use, bubbly and at peak activity
- 300 ml full-fat buttermilk room temperature
- 450 g bread flour plus extra for dusting
- 50 g whole wheat flour
- 10 g fine sea salt
- 1 tablespoon honey
- 50 ml warm water approximately 80°F (27°C), add as needed
Instructions
- In a large mixing bowl, whisk together the active sourdough starter, buttermilk, warm water, and honey until well combined. Add the bread flour and whole wheat flour and mix with your hand or a dough scraper until no dry flour remains. The dough will feel shaggy at this stage. Cover the bowl with a damp towel or plastic wrap and let it rest for 30 minutes at room temperature. This autolyse step allows the flour to fully hydrate.
- After the autolyse, sprinkle the fine sea salt evenly over the dough. Use wet hands to pinch and squeeze the salt into the dough, folding it over itself repeatedly for about 2 minutes until the salt is fully incorporated and the dough feels cohesive.
- Perform 4 sets of stretch and folds over the next 2 hours, spacing each set 30 minutes apart. For each set, wet your hand, grab one side of the dough, stretch it up as high as it will go without tearing, then fold it over to the opposite side. Rotate the bowl 90 degrees and repeat until you have completed all four sides. Cover the bowl between sets.
- After completing the stretch and folds, allow the dough to bulk ferment at room temperature (ideally 75 to 78 degrees Fahrenheit) for another 2 to 3 hours. The dough is ready when it has increased in volume by about 50 percent, looks airy with bubbles visible on the surface and sides, and has a domed top. Timing will vary based on the temperature of your kitchen and the strength of your starter.
- Turn the dough out onto a lightly floured surface. Using a bench scraper, gently pre-shape it into a round by tucking the edges underneath and dragging it toward you to build surface tension. Cover loosely with an inverted bowl or plastic wrap and let it rest uncovered for 20 minutes.
- For the final shape, flour your surface lightly. Flip the pre-shaped round so the smooth side is down. Fold the left and right sides into the center, then fold the top down and roll the dough toward you, sealing the seam. Drag the shaped loaf across the counter a few times with your bench scraper to create tight surface tension. Place it seam-side up into a well-floured banneton basket or a bowl lined with a generously floured kitchen towel.
- Cover the banneton tightly with plastic wrap or place it inside a large plastic bag. Refrigerate for 8 to 16 hours. This cold proof slows fermentation, develops the flavor of the buttermilk sourdough, and makes the dough easier to score cleanly straight from the fridge.
- When you are ready to bake, place your Dutch oven (with its lid) inside your oven and preheat to 500 degrees Fahrenheit (260 degrees Celsius). Allow the Dutch oven to heat for a full 45 minutes so it is thoroughly hot. Do not rush this step.
- Remove the cold dough directly from the refrigerator. Cut a piece of parchment paper to fit your Dutch oven. Turn the dough out onto the parchment paper so the smooth side is now facing up. Using a sharp bread lame or razor blade held at a 30 to 45 degree angle, make one confident slash about half an inch deep across the top of the loaf. You can also create a decorative scoring pattern if desired.
- Using oven mitts, carefully remove the hot Dutch oven from the oven. Lower the dough (on the parchment paper) into the Dutch oven. Place the lid on top and return it to the oven. Bake covered at 500 degrees Fahrenheit for 20 minutes. The steam trapped inside will create the open ear and blistered crust characteristic of artisan bread.
- After 20 minutes, carefully remove the Dutch oven lid. Reduce the oven temperature to 450 degrees Fahrenheit (230 degrees Celsius). Continue baking uncovered for 20 to 25 minutes until the crust is a deep mahogany brown. Use an instant-read thermometer to check doneness: the internal temperature should read between 205 and 210 degrees Fahrenheit.
- Remove the loaf from the Dutch oven and transfer it to a wire cooling rack. Allow it to cool for a minimum of 1 hour before slicing. Cutting into a hot loaf releases steam prematurely and results in a gummy, undercooked-tasting crumb. The bread will continue to set as it cools.
Notes
Make sure your sourdough starter has been fed within 4 to 8 hours and passes the float test before using. Bulk fermentation time varies with kitchen temperature, so watch the dough rather than the clock. A cold proof of up to 16 hours in the refrigerator will produce the most flavorful loaf. Do not skip preheating the Dutch oven for the full 45 minutes. Store cooled bread cut-side down on a wooden board for up to 3 days, or freeze sliced for up to 3 months.
Make It Your Own
- Herb and garlic swirl: Mix softened butter with roasted garlic and fresh rosemary, spread over the shaped dough before the final fold for a savory, aromatic loaf.
- Seeded crust: Before baking, brush the top with water and press on a mixture of sesame seeds, poppy seeds, and flaxseeds for crunch and visual appeal.
- Whole grain boost: Replace up to 100g of the bread flour with spelt or rye flour for a heartier, earthier crumb that pairs beautifully with aged cheeses.
- Dairy-free version: Swap the buttermilk for a mixture of oat milk and one tablespoon of apple cider vinegar, left to curdle for five minutes. The flavor changes subtly but the texture remains tender.
How to Make Sourdough Buttermilk Bread
- Mix the dough: Whisk together your active sourdough starter, buttermilk, warm water, and honey in a large bowl until combined. Add both flours and mix until no dry flour remains. Cover and rest for 30 minutes (autolyse).
- Add the salt: Sprinkle the sea salt over the rested dough and work it in thoroughly using your fingers, pinching and folding the dough for about 2 minutes until fully incorporated.
- Stretch and fold: Over the next 2 hours at room temperature, perform 4 sets of stretch and folds, spaced 30 minutes apart. Each set consists of grabbing one side of the dough, stretching it upward, and folding it over to the opposite side, rotating the bowl 90 degrees and repeating 4 times.
- Bulk fermentation: After the folds, leave the dough covered at room temperature (ideally 75 to 78 degrees Fahrenheit) for another 2 to 3 hours until it has grown by about 50 percent and looks airy and domed.
- Shape the loaf: Turn the dough onto a lightly floured surface and pre-shape it into a round. Rest uncovered for 20 minutes, then do a final shape, building surface tension by dragging the dough toward you across the counter.
- Cold proof: Place the shaped loaf seam-side up into a floured banneton or a bowl lined with a floured kitchen towel. Cover tightly and refrigerate for 8 to 16 hours.
- Preheat and score: The next day, place your Dutch oven in the oven and preheat to 500 degrees Fahrenheit (260 degrees Celsius) for at least 45 minutes. Remove the cold dough from the fridge, turn it onto parchment paper, and score the top decisively with a sharp lame or razor blade at a 30 to 45 degree angle.
- Bake covered: Carefully lower the dough (on parchment) into the hot Dutch oven. Cover with the lid and bake for 20 minutes. The steam trapped inside creates that signature blistered crust.
- Bake uncovered: Remove the lid and reduce heat to 450 degrees Fahrenheit (230 degrees Celsius). Continue baking for 20 to 25 minutes until the crust is a deep mahogany brown. Internal temperature should read 205 to 210 degrees Fahrenheit.
- Cool completely: Transfer to a wire rack and wait at least 1 hour before slicing. Cutting too early releases steam and turns the crumb gummy.
Tips for Best Results
- Check your starter honestly: A starter that is sluggish or smells overly alcoholic will produce a flat, dense loaf. Feed it twice the day before baking to make sure it is vigorous and passes the float test.
- Temperature matters more than time: Fermentation is driven by heat. On a cool day, your bulk ferment may take 5 hours; on a warm summer day, closer to 3. Watch the dough, not the clock.
- Do not skip the cold proof: This step is not just convenient, it is transformative. The slow cold retard develops flavor in buttermilk sourdough recipes that a same-day bake simply cannot match. It also makes the dough easier to score cleanly.
- Avoid under-baking: The biggest beginner mistake is pulling the loaf too early because the crust looks done. A pale interior crust means the crumb is still wet. Go darker than you think you need to.
Serving Suggestions
- Slice thick and spread with cultured butter and flaky sea salt for a breakfast that needs absolutely nothing else.
- Use as the base for a proper tartine topped with smashed avocado, a soft-boiled egg, and chili flakes.
- Pair with a hearty tomato soup for a lunch that feels like a warm hug on cold days.
- Toast slices lightly and serve alongside a cheese board with sharp cheddar, fig jam, and toasted walnuts.
- Use day-old slices for an outstanding French toast or savory bread pudding, since the tang of sourdough buttermilk plays beautifully against egg custard.
Make Ahead and Storage
- Room temperature: Store the fully cooled loaf cut-side down on a wooden board or wrapped loosely in a clean kitchen towel for up to 3 days. Avoid plastic bags, which soften the crust.
- Refrigerator: Not recommended for whole loaves as the cold environment stales bread faster, but sliced bread stored in an airtight bag keeps well for up to 5 days.
- Freezer: Slice the entire loaf before freezing. Lay slices flat on a baking sheet to freeze individually, then transfer to a zip-lock freezer bag. Keeps beautifully for up to 3 months.
- Reheating: Toast frozen slices directly from the freezer. To refresh a whole loaf, run it briefly under cold water and bake at 400 degrees Fahrenheit for 10 to 12 minutes for a crust that tastes freshly baked.
Frequently Asked Questions
Can I use store-bought buttermilk or do I need to make my own?
Store-bought buttermilk works perfectly and is actually preferred here for its consistent acidity. If you only have regular milk, stir in one tablespoon of white vinegar or lemon juice per cup and let it sit for 5 minutes to create a reliable substitute.
My dough feels very sticky. Is that normal for sourdough buttermilk recipes?
Yes, the added fat and liquid from buttermilk makes this dough a little tackier than a standard sourdough. Resist the urge to add extra flour. Wet hands and a bench scraper are your best friends during shaping.
Can I make this without a Dutch oven?
A Dutch oven creates the steam environment that gives artisan bread its crust, but you can improvise. Bake the loaf on a preheated baking stone or heavy sheet pan and place a shallow pan of boiling water on the rack below for the first 20 minutes of baking.
How do I know my sourdough starter is strong enough for this loaf?
Feed your starter, mark the level with a rubber band, and check it after 4 to 6 hours. If it has doubled or more and smells pleasantly yeasty and sour (not like nail polish remover), it is ready to go.
