Sourdough Potato Buns

These sourdough potato buns are a favorite in our house. Light and fluffy and a bit sour, they would make a lovely accompaniment to Christmas dinner, but also pair well with a bowl of soup or with a cup of tea.

This recipe calls for sourdough starter. If you don’t have a starter, don’t worry, you can make your own very easily, it just requires a bit of time. Check out this blog post for more details about getting started with sourdough.

To make these tasty buns, you will need:

  • 2 cups mashed potatoes 
  • 1 cup sourdough starter
  • 2 Tbsp butter
  • 1 cup water
  • 2 tsp salt
  • 2 cups whole wheat flour
  • 3 cups white flour

Makes 12 buns.


Peel, boil, and mash the potatoes. Then set them aside to cool down. 

Once the potatoes have cooled, add them to a large mixing bowl with the sourdough starter, salt, butter, and water and stir until well combined.

Add the flour, one cup at a time until the dough becomes too stiff to stir. Then turn it out onto a clean, lightly floured surface and knead in the rest of the flour. You may need to use a little more or less flour depending on the consistency of your sourdough starter. 

Place the dough in a bowl and cover with a silicone bowl cover. Proof the dough overnight (8-12 hours) at room temperature. The dough will poof up and fill the bowl. 

After the dough has proofed, form small balls, about the size of an orange and place on a lightly oiled baking sheet. Then proof the rolls for another 1-2 hours. 

Bake the buns at 350°F for about 25 minutes, or until the rolls sound hollow when you tap on their crusts.

Enjoy these homemade sourdough buns lathered in butter or spread with a bit of jam or honey.
