Ingredients
This easy sourdough discard sandwich bread recipe combines leftover starter with commercial yeast for a soft, tender loaf. Perfect for everyday sandwiches, it has a light texture and a simple process that makes it beginner-friendly.
For the Bread
- 120g (½ cup) lukewarm water
- 120g (½ cup) lukewarm milk
- 7g (2 ½ tsp) instant yeast (or active dry yeast)
- 25g (2 tbsp) granulated white sugar
- 406g (3 ¼ cups) bread flour or strong all-purpose flour
- 100g (approx. ½ cup) sourdough discard
- 8g (1 ½ tsp) salt
- 45g (3 tbsp) room-temperature butter

How to Make Sourdough Discard Sandwich Bread
Step 1: Mixing & First Rise
- In a large bowl, combine lukewarm water, milk, sugar, and yeast. If using active dry yeast, let sit for 5-10 minutes until foamy; if using instant yeast, proceed immediately.
- Add the flour, sourdough discard, and salt. Mix with a fork or wooden spoon until a shaggy dough forms.
- Add the softened butter and knead it into the dough by hand until fully combined.
- Transfer the dough to a lightly floured surface and knead for 8-10 minutes until soft, smooth, and elastic. Alternatively, use a stand mixer with a dough hook.
- Place the dough in a lightly greased bowl, cover with a damp towel, and let rise in a warm place for 1 to 1 ½ hours until doubled in size.
- Optional cold-proof: Refrigerate overnight for enhanced flavor and texture.
Step 2: Shaping & Second Rise
- Punch down the dough and turn it onto a lightly floured surface. Line a 9×5-inch loaf pan with parchment paper.
- Flatten the dough into a rectangle slightly shorter than the length of the loaf pan. Orient it so that the long sides are left and right.
- Fold the top third of the dough toward the center and press along the fold to seal. Repeat this folding and sealing process two more times.
- Place the shaped dough seam-side down in the lined loaf pan. Cover loosely with a kitchen towel or plastic wrap and let rise until it doubles in size and rises about 1 inch above the pan’s rim.
Step 3: Baking
- Preheat your oven to 350°F (180°C) while the dough rises.
- Bake for about 35 minutes until deep golden brown. If the top browns too quickly, tent loosely with foil after 20 minutes.
- The bread is done when it sounds hollow when tapped and reaches an internal temperature of 200°F (94°C).
- Remove from the pan and cool completely before slicing.
Step 4: Storing
Store at room temperature in an airtight container for up to 4-5 days or freeze for up to three months.
