By late September, my kitchen counter usually has at least one can of pumpkin puree sitting next to my kefir jar, and this loaf is the reason why. Real pumpkin puree does something to sourdough dough that’s hard to describe until you’ve felt it, it goes soft and almost velvety, and the loaf bakes up with this deep golden-orange color that looks like fall even before you add a single spice.
The pumpkin pie spice here is doing double duty, working with the natural tang from the kefir and starter instead of just sitting on top of it. I’ve made this loaf with just cinnamon before, and it’s good, but the full pumpkin pie spice blend (nutmeg, ginger, cloves, and all) is what makes people ask what your secret ingredient is. This one disappears fast whenever I bring it to a fall gathering, usually before I even get a slice for myself.
Why This Recipe Works
- Kefir adds gentle tang. The natural sourness in kefir balances the sweetness from the pumpkin and brown sugar, keeping the loaf from tasting like cake.
- Real pumpkin, real color. Pumpkin puree gives this loaf its signature golden-orange crumb and a soft, tender texture.
- Full spice blend. Using real pumpkin pie spice, not just cinnamon, gives this loaf that unmistakable fall flavor people recognize instantly.
- Naturally fermented. No commercial yeast, just a slow rise that builds real sourdough flavor and structure.
Basic Equipment You’ll Need
- Kitchen scale – for accurate flour, kefir, and pumpkin measurements
- Large mixing bowl – for mixing and bulk fermentation
- Dutch oven – traps steam for a crisp, golden crust
- Banneton or bowl lined with a towel – holds the loaf’s shape while it rests
- Bench scraper – helps handle and shape the dough
- Lame or sharp razor blade – for scoring the top of the loaf
- Parchment paper – makes it easy to lower the dough into the hot Dutch oven
- Wire cooling rack – lets air flow under the loaf as it cools
Pumpkin Spice Kefir Sourdough Bread
Ingredients
Equipment
Method
- Mix the dough: In a large bowl, whisk 100 grams plain whole milk kefir, 150 grams pumpkin puree (not pumpkin pie filling), 100 grams water, and 100 grams active sourdough starter together until smooth. Add 450 grams bread flour, 50 grams whole wheat flour, and 30 grams brown sugar. Mix until no dry flour remains. Cover and rest 30 minutes.
- Add salt and spice: Sprinkle 9 grams fine sea salt and 2 teaspoons pumpkin pie spice over the dough. Pinch and fold until fully worked in. Cover and rest 30 minutes.
- Stretch and fold: Do 3 sets of stretch and folds, 90 minutes apart. Turn the bowl and fold each side into the middle each time.
- Bulk ferment: Cover the dough and let it rise at room temperature until it grows by about 50%. This takes 4 to 270 minutes depending on how warm your kitchen is.
- Shape the loaf: Turn the dough onto a lightly floured surface. Shape into a round or oval loaf. Place seam-side up in a floured banneton or bowl lined with a towel.
- Cold retard overnight: Cover the banneton and place it in the fridge for 8 to 480 minutes. This builds flavor and makes the dough easier to score.
- Preheat and score: Preheat your oven to 450°F (230°C) with a Dutch oven inside for 30 minutes. Turn the cold dough onto parchment paper. Score the top with a sharp blade, or try a leaf pattern for a festive look.
- Bake: Place the dough into the hot Dutch oven with the lid on. Bake 45 minutes covered, then remove the lid and bake 20 to 25 minutes more, until deep golden brown.
- Cool completely: Move the loaf to a wire rack. Let it cool for at least 60 minutes before slicing. Cutting too early makes the inside gummy.
Notes
Recipe Details
Why Use Kefir Alongside Pumpkin
Kefir adds a gentle tang that balances the natural sweetness of the pumpkin and brown sugar. It works alongside your sourdough starter, not in place of it, the starter is still what makes the bread rise. Use plain, unsweetened whole milk kefir for the best flavor balance.
Pumpkin Puree vs. Pumpkin Pie Filling
These are not the same thing, and it matters here. Plain pumpkin puree is just cooked, pureed pumpkin. Pumpkin pie filling already contains added sugar and spices, which will throw off both the sweetness and hydration of this dough. Always check the can label carefully.
Why This Dough Feels Softer
Pumpkin puree adds extra moisture, so this dough will feel softer and slightly stickier than a plain sourdough. Resist the urge to add extra flour. Wet hands during shaping make it much easier to handle.
Why the Dough Rests So Long
Sourdough relies on wild yeast in your starter, which works much slower than store-bought yeast. This slow rise is what gives the bread its tangy flavor and chewy texture, while also giving the pumpkin and spices time to fully infuse the dough. Do not rush this step, even on a warm day.
Storing Your Loaf
- Room temperature: Keep in a paper bag or bread box for up to 2 days.
- Fridge: Wrap tightly and store up to 1 week, though the crust will soften.
- Freezer: Slice first, then freeze in a sealed bag for up to 3 months. Toast slices straight from frozen.
Ways to Serve It
Toast a slice and top it with cream cheese and a drizzle of honey, or serve it warm alongside a bowl of soup on a chilly evening. It also makes a wonderful French toast for a fall breakfast.

Recipe Notes
- Use plain, unsweetened whole milk kefir for the best flavor balance with the pumpkin.
- Double check your can says “pumpkin puree,” not “pumpkin pie filling,” which contains added sugar and spices.
- This dough is softer than a typical sourdough because of the pumpkin. Use wet hands instead of extra flour when shaping.
- Make sure your sourdough starter is active and bubbly before you begin. It should double in size within 4 to 6 hours of feeding.
- Do not skip the cold retard step. Resting the shaped dough in the fridge overnight makes it easier to score and deepens the flavor.
- Let the loaf cool for at least 1 hour before slicing so the inside doesn’t turn gummy.

Frequently Asked Questions
Can I use fresh roasted pumpkin instead of canned puree?
Yes, as long as it’s well-drained. Fresh pumpkin puree can hold more water than canned, so straining it through a cheesecloth first helps avoid an overly wet dough.
Can I use just cinnamon instead of pumpkin pie spice?
You can, but the flavor will be much less complex. Pumpkin pie spice’s blend of cinnamon, nutmeg, ginger, and cloves is what gives this loaf its classic fall flavor.
Why is my dough so much stickier than my usual sourdough?
Pumpkin puree adds extra moisture, which raises the hydration of this dough compared to a plain loaf. Use wet hands rather than extra flour when handling it.
Do I need a Dutch oven to bake this bread?
A Dutch oven traps steam and gives the best crust, but you can also bake on a hot baking sheet with a pan of water in the oven to create steam.
Why is my sourdough bread dense instead of airy?
Dense bread is often a sign of an underfed or weak starter, or not enough bulk fermentation time. Make sure your starter doubles in size before you start, and let the dough rise until it looks puffy and full of air pockets.
How do I know when bulk fermentation is done?
The dough should look about 50% bigger, feel light and jiggly when you shake the bowl, and show small bubbles on the surface. Watch the dough, not the clock, since timing changes with kitchen temperature.
