Why This Recipe Works

Experience the delightful magic of your potato flake sourdough starter in this recipe for incredibly soft and fluffy Potato Flake Sourdough Bread! This unique bakes into a tender white loaf with a wonderfully subtle tang that will elevate your everyday sandwiches and toast.

  • Unbelievably Soft Texture: The addition of potato flakes creates a truly tender crumb.
  • Subtle Sourdough Tang: Enjoy that classic sourdough flavor without being overpowering.
  • Gluten-Free Starter: That's right, not only is the starter gluten-free, but if you were to swap out the bread flour for a 1:1 gluten-free flour, you'd have a gluten-free sourdough bread!
  • A Great Everyday Bread: Ideal for toast, sandwiches, and enjoying with meals.

Ingredients Overview

You'll need an active potato flake sourdough starter to provide the leavening and that subtle tang. Warm milk helps to create a tender and moist crumb, while a touch of granulated sugar adds a hint of sweetness. Melted butter or olive oil enhances the overall softness. Bread flour forms the main body of the bread, and salt balances all the delightful flavors.

How To Make Potato Flake Sourdough Bread

Creating this soft Potato Flake Sourdough Bread involves combining an active potato flake sourdough starter with warm milk, sugar, and melted butter. Flour and salt are then mixed in to form a smooth dough that undergoes two rising periods to develop its airy texture.

Finally, the shaped loaf is baked until golden brown and wonderfully tender.

Day 1 - In the Evening

  1. Using a large bowl or stand mixer with a dough hook, add the potato flake sourdough starter, bread flour, salt, sugar, melted butter, and the warm milk.
  2. Mix the ingredients until you get a shaggy dough. Tip out onto a floured work surface and knead, or use a stand mixer to continue mixing for 5 to 10 minutes, until dough is smooth and elastic.
  3. Place the dough ball in oiled bowl and cover with a cloth or a loose disposable shower cap. Place in a draft-free place to rise overnight (at least 12 hours).

Day 2 - Next Morning

  1. Punch the dough down and turn out onto a lightly floured surface. Knead for a few minutes to remove any air bubbles.
  2. Butter or oil a loaf pan. Shape the dough either into a loaf and place in the prepared pan. Cover loosely with a clean cloth or disposable shower cap, and let rise for 6 to 8 hours.

  1. Preheat your oven to 350° F (177° C) the last 20 minutes of the proofing.
  2. Place the pan on the middle rack and bake at 350° F (177° C) for 30-35 minutes or until the top is golden and the bread has pulled away from the sides of the pan.
  3. Remove from the oven and brush the tops with melted butter. Cool on a wire rack before slicing the loaves.

Tips for Success

Here are a few tips for making this recipe:

Can I use starter that hasn't been recently fed?

Yes, you can use some of the discarded potato flake sourdough discard, the bulk proofing may just take a little longer.

It should be golden brown, sound hollow when tapped, and have an internal temperature of 200-210°F (93-99°C).

I love bread! I started making bread when I was 21 and working at a Jewish bakery. I loved to watch the bakers as they made ginormous batches of bagels, challah, rye bread, and Hamenstachen cookies.
