Have you ever tried purple sweet potato sourdough bread? If not, you’re about to discover a true baking marvel. In this article, we’ll dive into the recipe for this incredible bread and teach you step-by-step how to prepare it in your own kitchen.
Ingredients for Purple Sweet Potato Sourdough Bread:
- 2 1/2 cups (300g) all-purpose flour
- approx. 1/2 cup (100g) cooked and mashed purple sweet potato
- 1/3 cup (80g) active sourdough starter (fed)
- *approx. 3/4 cup to 1 cup (220ml) water (you may need less depending on the flour’s hydration)
- 1 tablespoon (15g) salt
How to Make Purple Sweet Potato Bread:
- Start by preparing the potatoes. Roast the raw potatoes (wrapped in aluminum foil) in a 350°F oven for about 30 minutes until tender. Then, remove the skin and mash the potatoes until smooth.
- Now for the dough preparation. First, perform an autolyse by mixing the flour and water. Cover and let it rest for 1 hour.
- Incorporate the sourdough starter and let it rest for another 30 minutes.
- Next, add the mashed potatoes, mixing well until fully incorporated into the dough.
- Let the dough rest for another 30 minutes. Then, perform 3 sets of stretch-and-folds and coil folds to develop the gluten and ensure even fermentation.
- After the last set of folds, let it rest for 2 to 4 hours (until it has doubled in size).

- After fermentation, shape the bread and let it proof again, either at room temperature or in the refrigerator overnight for a more intense flavor.
- Once the final proofing is done, preheat your oven to its maximum temperature.

- Place the loaf on a baking sheet lined with parchment paper and score the top diagonally using a razor blade or lame.

- Place a baking dish with boiling water at the bottom of the oven to create steam, which helps form a crispy crust.
- Bake with steam at the maximum temperature for 20 minutes.
- Then remove the water dish, lower the temperature to 350°F, and bake for another 25 minutes. Remove from the oven, let cool, and enjoy!

Pro Tip:
Roast the potatoes instead of boiling them in water to maintain their vibrant color and avoid excess moisture in the dough.
