A lightly spiced sourdough loaf featuring pumpkin puree for moisture and flavor, with a crisp crust and tender crumb. Perfect for fall breakfasts and soups.
Feed your starter 4–8 hours before mixing so it’s active and bubbly.
Whisk together bread flour, whole wheat flour, cinnamon, nutmeg, ginger, and brown sugar in a large bowl.
Mix pumpkin puree and water until smooth, then stir in the active starter. Pour wet into dry and mix until just combined.
Let the shaggy dough rest 30 minutes, then sprinkle salt and fold to incorporate.
Perform 3–4 sets of stretch-and-folds every 30 minutes, then leave the dough to rise at room temperature until 30–50% increased in volume (3–5 hours).
Shape into a tight boule or batard, place seam-side up in a floured banneton, cover and refrigerate 8–18 hours.
Preheat oven to 475°F (245°C) with a Dutch oven inside. Flip dough onto parchment, score, and bake covered 20 minutes; uncover, reduce to 425°F (220°C) and bake 20–25 more minutes until golden and internal temp ~205–210°F.
Cool on a wire rack at least 1 hour before slicing.
Notes
If you prefer less sweetness, reduce or omit brown sugar.
Add nuts or seeds during the last fold for texture.
If your starter is slow, increase fermentation time rather than speeding the heat.
