It is officially FALL!! I’m knee deep in all the cozy recipes over here and am just waiting for the outside weather to follow suit. We all know Mother Nature makes her own rules, so I’ll be patient.

This pumpkin swirl sourdough bread recipe sings the praises of autumn. It made the house smell *so* good as I was baking it. This loaf would make a fantastic French toast, but is also lovely on its own, toasted with some butter. We devoured it!

Ingredients

Active sourdough starter – active, bubbly sourdough starter
Water
Honey
Pumpkin purée – I recommend using canned pumpkin here. Pumpkin puree already holds a lot of water, and it’s challenging to replicate the desired texture of the bread if you’re using fresh pumpkin.
Bread flour
Salt
Granulated sugar
Ground cinnamon

Step-By-Step Instructions

A glass bowl sits with the sourdough pumpkin swirl bread dough in it.

Step 1: Mix the Dough
Start by whisking together the water, honey, and active sourdough starter until smooth and bubbly. Stir in the pumpkin purée, then add the bread flour. Mix until no dry bits remain, cover the bowl, and let it rest for 30 minutes to hydrate the flour. After resting, sprinkle in the salt and gently work it into the dough until fully incorporated.

A glass mixing bowl sits with the pumpkin sourdough bread dough in it after a round of stretch and folds.

Step 2: Stretch and Fold
During the first 2 hours of bulk fermentation, perform 3–4 sets of stretch-and-folds, gently pulling and folding the dough over itself to develop gluten strength.

The glass mixing bowl sits with the fermented sourdough pumpkin swirl bread dough in it. The dough is now fermented--it's smoother and has a few bubbles on top.

Step 3: Complete Bulk Fermentation

Cover and continue fermenting until the dough is puffy, airy, and roughly doubled in size (about 4–6 hours, depending on room temperature).

The dough is stretched out into a rectangle with cinnamon and sugar sprinkled over the surface.

Step 4: Laminate and Add the Cinnamon Swirl
Lightly mist your counter with water and carefully turn the dough out. Stretch it into a large, thin rectangle—this is the lamination process, which creates thin layers and makes room for the filling. Sprinkle the cinnamon-sugar mixture evenly over the surface.

The dough is rolled lengthwise with a third of it folded over the dough. More cinnamon sugar mixture is sprinkled over it.

Step 5: Fold in Thirds
Add more of the cinnamon sugar mixture.

The other third of the dough is folded over the dough and more cinnamon sugar is sprinkled over this third too.

Step 6: Final Fold

Fold again lengthwise to add the last bit of cinnamon sugar.

The pumpkin swirl bread dough is rolled into a ball and sitting on the counter.

Step 7: Shape the Loaf
Gently shape the dough into a round or oval loaf, keeping as much air inside as possible for an open crumb. Place it seam side up in a floured banneton or lined bowl.

The dough sits on a bread sling after the overnight fermentation. The bread dough is scored.

Step 8: Final Proof
Cover and let the dough proof for 1–2 hours at room temperature, or refrigerate overnight for deeper flavor and easier scoring. The dough is ready when it feels slightly puffy and springs back slowly when pressed.

Step 9: Bake in a Dutch Oven
Preheat a Dutch oven inside your oven at 450°F (232°C) for 30–60 minutes. When ready to bake, carefully transfer the dough to the hot Dutch oven, score the top, and cover with the lid. Bake covered for 30 minutes, then remove the lid and bake uncovered for another 25 minutes, or until the crust is deep golden brown and the internal temperature reaches 205°F (96°C).

Step 10: Cool and Enjoy
Transfer the loaf to a wire rack and let it cool completely before slicing. This resting time sets the crumb and ensures clean slices with beautiful cinnamon swirls.

Helpful Tips for the Best Sourdough Pumpkin Swirl Bread

Use Active Starter: Make sure your sourdough starter is bubbly and active before mixing. A sluggish starter can slow fermentation and affect the rise.
Adjust Hydration if Needed: Pumpkin purée can vary in moisture. If your dough feels too wet or sticky, add a tablespoon of flour at a time until it’s manageable.
Bulk Fermentation Patience: Don’t rush the bulk rise. A well-fermented dough develops flavor and a better crumb. The dough should be puffy and slightly airy.
Gentle Lamination: When adding the cinnamon swirl, stretch carefully to avoid tearing the dough. The goal is thin layers without deflating the air pockets.
Even Cinnamon Sugar Distribution: Sprinkle the cinnamon sugar evenly and avoid clumps to get beautiful, consistent swirls in every slice.
Scoring is Key: A sharp blade or lame ensures your bread can expand properly in the oven without cracking in odd places.
Dutch Oven Tip: Preheat your Dutch oven thoroughly for a crisp crust. Baking covered traps steam, giving the bread a nice rise, while uncovering in the last 25 minutes gives a golden, caramelized crust.
Check Internal Temperature: Use an instant-read thermometer—205°F (96°C) is the sweet spot. This guarantees the bread is fully baked but still moist inside.
Cool Completely Before Slicing: Let the loaf cool on a wire rack for at least 2 hours. Slicing too early can compress the crumb and make it gummy.
Storage & Refresh: Store at room temperature for up to 3–4 days or freeze slices for up to 3 months. Warm slices in a 350°F oven for 10 minutes to refresh the crust.
Experiment with Add-ins: Optional: chopped pecans, walnuts, or raisins can be sprinkled on top of the cinnamon sugar during lamination for added texture and flavor.

Equipment Needed

Large mixing bowl
Digital kitchen scale
Measuring cups and spoons (for U.S. measurements, if needed)
Danish whisk or sturdy spoon (for mixing)
Plastic dough scraper or bench scraper
Spray bottle or mister (for lightly misting the counter during lamination)
Banneton basket or bowl lined with a tea towel (for proofing)
Sharp lame or razor blade (for scoring)
Parchment paper (optional, for easier transfer)
Dutch oven with lid (for baking)
Wire cooling rack
Instant-read thermometer (to check the internal temperature reaches 205°F / 96°C)

Storage

Room Temperature: Store the cooled loaf in a paper bag or wrapped in a clean kitchen towel inside a bread box for up to 3–4 days. Avoid plastic if possible—it traps moisture and softens the crust.
Freezer: Slice the bread and freeze individual slices in a zip-top bag or airtight container for up to 3 months. Toast or warm slices straight from frozen.
Refresh: To revive a day-old loaf, place it in a 350°F (175°C) oven for 10–15 minutes to crisp the crust before serving.
