This sourdough discard sandwich bread is tried and true! I make it at least once a week for my family, and it's a recipe I know by heart — the most consistent, fluffy, delicious loaf I've ever had.
It's wonderful for sandwiches, toast, and sourdough French toast (try it with my sourdough pumpkin French toast for a festive breakfast). If you're after another quick discard bread, my sourdough discard ciabatta rolls are a great next bake.

Why You'll Love This Recipe
- A perfect use for sourdough discard. It adds subtle tang and tenderness while using up what you'd otherwise toss — like my sourdough discard bagels.
- Reliable rise. A touch of active dry yeast means you don't have to wait on a long sourdough ferment.
- Soft and fluffy. A tender, even crumb that slices cleanly for sandwiches and toast.
- Makes incredible French toast. The slightly tangy crumb soaks up custard beautifully, just like my braided cardamom bread — perfect for my sourdough French toast.
- A weekly staple. Simple enough to make on repeat, with everyday pantry ingredients.

Ingredients
- Water: Warmed to 110–120°F to bloom the yeast.
- Active dry yeast: Gives this loaf its quick, reliable rise (more on why below).
- Unsalted butter: Softened, for a tender, rich crumb.
- Sugar: Feeds the yeast and lightly sweetens the dough.
- Unfed sourdough discard: Adds flavor and tenderness — a great way to use it up, like in my sourdough discard cinnamon swirl bread.
- All-purpose flour: The structure of the loaf (bread flour works too — see variations).
- Salt: Balances the flavor.
See the recipe card for quantities.
Easy Substitutions & Variations
- Dairy-free: Use a plant-based butter (it works great here and in frosting too).
- Flour: All-purpose or bread flour both work. For a whole-grain flavor, swap 100–150g of the flour for whole wheat — enough for pronounced wheat flavor while keeping the loaf soft.
- Shape it into buns: Use the same dough approach behind my soft sourdough discard burger buns and sourdough discard hot dog buns.
- Make it sweet: For a sweeter loaf, try my sourdough discard cinnamon swirl bread, which is based on this very recipe.
How to Make Sourdough Discard Sandwich Bread
Weigh your ingredients! Using a kitchen scale ensures your measurements are accurate, which is key for getting consistent results in baking. It takes the guesswork out of measuring and helps your recipes turn out exactly as intended every time.
Expert Tips
- Use warm — not hot — water. Aim for 110–120°F. Too hot and you'll kill the yeast; too cold and it won't bloom.
- Let the yeast bloom fully. Wait until it's foamy before adding the rest of the ingredients, so you know it's alive.
- Don't skimp on the second rise. Skipping it leads to the loaf splitting in the oven — let it get nice and puffy over the rim.
- Weigh your discard and flour. A scale keeps the hydration consistent loaf to loaf.
- Cool completely before slicing. It's tempting to cut in warm, but cooling sets the crumb for clean slices.
What Makes This Recipe Special?
Traditional sourdough relies on wild yeast, which takes hours of feeding and proofing. This loaf uses sourdough discard for flavor and a little active dry yeast for lift, so you get that subtle tang and tender crumb in about two hours instead of all day. It's the everyday workhorse loaf — reliable enough to make weekly without thinking twice.
It's also the foundation for a whole family of discard bakes on the blog. Once you've mastered it, try shaping the dough into my same-day sourdough crescent rolls or my sourdough discard garlic butter dinner rolls for the dinner table.
Sourdough Discard Sandwich Bread FAQs
Sourdough starter is roughly half flour and half water, so to add discard to an existing recipe, subtract half the discard's weight from the flour and half from the liquid. For example, to add 100g of discard to a recipe with 500g flour and 250g liquid: remove 50g flour and 50g liquid, leaving 450g flour and 200g liquid.
Traditional sourdough takes a long time to rise because it relies on wild yeast, which has to be fed and activated. Since this recipe uses sourdough discard rather than active starter, it can't create enough rise on its own — so we add active dry yeast, which is ready in about 5 minutes with a little warm water and sugar.
Yes — active starter works too. You can reduce the added yeast since the active starter contributes some rise, but keeping the yeast ensures a reliable result.
Absolutely. Mix and knead by hand on a floured surface until the dough is soft and smooth (about 10 minutes).
Yes — my soft sourdough sandwich bread is the naturally-leavened version if you'd rather skip the discard and yeast combo.
Sourdough Discard Sandwich Bread Troubleshooting Guide
| Problem | Cause | Fix |
|---|---|---|
| Loaf split on the side | Under-proofed second rise. | Let the shaped loaf rise until puffy and risen above the rim before baking. |
| Dense, heavy loaf | Yeast was dead or water too hot. | Use water around 110–120°F and make sure the yeast foams during blooming. |
| Dough didn't rise | Old yeast or a cold kitchen. | Use fresh yeast and let it rise somewhere warm and draft-free. |
| Gummy slices | Cut while still warm. | Cool the loaf completely before slicing. |
| Crumbly or dry dough | Too much flour. | Weigh your ingredients; add a splash of water if needed while kneading. |
Storage
- Store at room temperature in an airtight container or bread bag for 5–7 days.
- Slice before freezing so you can pull out what you need; freeze for up to 3 months.
- Day-old slices are excellent toasted or used for French toast.

Quick Sourdough Discard Sandwich Bread
Equipment
- Stand Mixer optional
- Dough hook attachment
- Kitchen Scale
- Loaf Pan Roughly 9x4
- Plastic wrap
Ingredients
- 250 g water 1 cup, warmed to 110–120°F
- 1 teaspoon active dry yeast
- 56 g unsalted butter softened (4 tablespoons)
- 25 g sugar 2 tablespoons
- 100 g unfed sourdough discard ⅓ cup
- 500 g all-purpose flour about 4 cups
- 10 g salt 1½ teaspoons
Instructions
Make the dough
- Add the warm water (110–120°F), yeast, and sugar to the bowl of a stand mixer or a mixing bowl. Mix with a fork until combined (it's okay if it's clumpy) and let sit about 5 minutes, until the yeast blooms.250 g water, 1 teaspoon active dry yeast, 25 g sugar
- Add the remaining ingredients — softened butter, sourdough discard, flour, and salt. Turn the mixer on the lowest setting with the dough hook.56 g unsalted butter, 100 g unfed sourdough discard, 500 g all-purpose flour, 10 g salt
- Let the mixer work until the dough forms a soft, smooth ball, then knead another 8–10 minutes (keep an eye on your mixer so it doesn't overheat).
First rise
- Lightly grease a medium bowl, add the dough, and turn to coat. Cover with plastic wrap and let rise 1–2 hours, until doubled.
Second rise
- Line or grease a loaf pan. Turn the dough onto a lightly floured surface and gently stretch it into a rectangle (the short side roughly the length of the loaf pan). Roll it up from the short side, pinch the seam, tuck the ends, and place it in the prepared pan.
- Cover with plastic wrap and a clean tea towel and let rise another 1–2 hours, until puffy over the top of the pan.
Bake
- Once fully risen, preheat the oven to 375°F and bake 30 minutes, until golden brown.
- Cool in the pan 10 minutes, then transfer to a cooling rack and cool completely before slicing for the best results.
Notes
This bread lasts at room temperature for 5–7 days.
