Recipe Tips
Use active discard: Even though the discard is unfed, it should still be relatively fresh (within a week) for the best flavor and texture. Older discard can add a stronger tang but may affect the dough’s strength.
Warm water for a better rise: Using lukewarm water (around 100°F/38°C) helps activate the yeast and speeds up fermentation.
Let it rise fully: Underproofing can lead to a dense loaf, while overproofing may cause the bread to collapse. The dough should rise until it’s about an inch above the pan before baking.
Steam for a better crust: Placing a small pan of hot water in the oven during baking can help create a softer crust.
Cool completely before slicing: Cutting too soon releases steam, making the bread gummy instead of soft and fluffy. Let it cool for at least an hour.
Store properly: Keep the bread in an airtight container or wrapped in a clean kitchen towel to maintain freshness. It stays fresh for about 3–4 days at room temperature. For longer storage, slice and freeze it.

Equipment
- Mixing Bowl: To combine and mix the dough ingredients.
- Stand Mixer (Optional): Makes kneading easier with a dough hook attachment.
- Wooden Spoon or Dough Whisk: For mixing the dough before kneading.
- Bench Scraper: Helps with handling and shaping the dough.
- Floured Work Surface: For kneading and shaping the dough.
- Loaf Pan (9×5-inch): Shapes the bread as it bakes for a classic sandwich loaf.
- Kitchen Towel or Plastic Wrap: Covers the dough during rising to prevent drying out.
- Oven: Bakes the bread to golden perfection.
- Wire Rack: Allows the bread to cool evenly after baking.
Ingredients
- Sourdough Discard: adds depth of flavor and a slight tang while reducing waste from your sourdough starter.
- Water: warm water
- Flour: all-purpose or bread flour works for this recipe, bread flour will make it a little more lighter and chewier.
- Salt
- Sugar: granulated sugar
- Butter: cooled and melted
- Instant Yeast: speeds up fermentation, ensuring a quicker rise while still allowing the sourdough discard to shine.

How to Make Sourdough Discard Sandwich Bread
Mix the dough: In a large mixing bowl, combine the sourdough discard, water, flour, salt, sugar, and yeast. Mix until a shaggy dough forms. Add the melted butter and continue mixing until the dough starts coming together.
Knead the dough: Transfer the dough to a lightly floured surface and knead for about 8–10 minutes until it becomes smooth and elastic. If using a stand mixer, knead with the dough hook on medium speed for 5–7 minutes.
First rise: Place the dough in a greased bowl, cover with a damp towel, and let it rise in a warm place for about 1–1.5 hours, or until doubled in size.
Shape the dough: Gently deflate the dough and shape it into a log. Place it into a greased 9×5-inch loaf pan, seam side down.
Second rise: Cover the pan and let the dough rise for another 45–60 minutes, or until it puffs up just above the rim of the pan.
Bake: Preheat the oven to 375°F (190°C). Bake for 30–35 minutes, or until the top is golden brown and the loaf sounds hollow when tapped.
Cool and enjoy: Let the bread cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely before slicing. Enjoy!
