Ingredients
Instructions
1. Combine Wet Ingredients: In a large mixing bowl, whisk together the sourdough discard, warm water, granulated sugar, salt, and olive oil until well combined. The mixture should look slightly milky and smooth.
2. Add Dry Ingredients: Gradually add the all-purpose flour and instant yeast to the wet mixture. Start by adding about half the flour, mix until just combined, then add the rest.
3. Form the Dough: Mix with a sturdy spoon or your hands until a shaggy dough forms. It might seem a bit sticky at first.
4. Knead Until Smooth: Turn the dough out onto a lightly floured surface and knead for 5-7 minutes. The dough should become smooth, elastic, and less sticky, bouncing back slightly when poked. If it’s too sticky, add a tiny bit more flour, one tablespoon at a time.
5. First Rise (Proofing): Lightly grease a clean bowl with olive oil, place the dough inside, and turn it once to coat. Cover the bowl with plastic wrap or a clean kitchen towel and let it rise in a warm place for 45-60 minutes, or until it has nearly doubled in size. The dough should look puffy and feel light.
6. Shape and Second Rise: Gently punch down the risen dough to release the air. On a lightly floured surface, shape the dough into a rectangle that fits your standard loaf pan (approximately 9×5 inches). Place the shaped dough into a lightly greased loaf pan. Cover loosely with plastic wrap or a towel and let it rise again for another 20-30 minutes, or until it has risen above the rim of the pan. It should look airy and soft.
7. Preheat and Bake: While the dough is on its second rise, preheat your oven to 375 F (190 C). Once the dough has risen, place the loaf pan in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the internal temperature reaches 200-210 F (93-99 C) when checked with an instant-read thermometer.
8. Cool Completely: Remove the loaf from the oven and immediately turn it out onto a wire rack to cool completely before slicing. This prevents the bottom from becoming soggy and allows the internal structure to set properly. Cooling takes at least 1 hour.

What You’ll Love About This Quick And Easy Recipe
This recipe is a true lifesaver for anyone with an active sourdough starter, especially if you find yourself with a growing stash of discard. It’s designed for simplicity and speed, making it perfect for novice bakers or those who need a reliable bread recipe without the fuss. You’ll love how quickly this comes together, yielding a tender, flavorful loaf that’s far superior to store-bought options. It’s ideal for family dinners, packing into lunchboxes, or serving as a comforting snack. The subtle sourdough flavor elevates any sandwich filling, and the soft texture is universally appealing, even to picky eaters. This isn’t a crusty, artisanal loaf, but rather a soft, pliable bread specifically crafted for easy slicing into sandwich-ready squares.
Everything You Need To Make This Recipe Without Stress
Gathering your ingredients before you start is the first step to a stress-free baking experience. This recipe uses common pantry staples alongside your sourdough discard, so you likely have most of what you need on hand already.
INGREDIENTS:

- 1 cup active sourdough discard (unfed, at room temperature)
- 1 cup warm water (about 100-110°F)
- 2 tablespoons granulated sugar
- 1 teaspoon salt
- 3 tablespoons olive oil (plus more for greasing)
- 3 cups all-purpose flour
- 2 teaspoons instant yeast
After you’ve got your main ingredients, consider a few simple substitutions if needed. If you don’t have olive oil, any neutral-flavored oil like vegetable or canola oil will work just fine. For a slightly richer flavor, you could use melted unsalted butter instead of olive oil. While all-purpose flour is recommended for its soft crumb, you could experiment with a small amount of bread flour (up to 1/2 cup) for a slightly chewier texture, but stick mostly to all-purpose for the softest squares. The instant yeast is crucial for a quick rise, so avoid substituting it with active dry yeast unless you’re prepared for a longer proofing time and an extra step to activate it.
Time Needed From Start To Finish
One of the best features of this sourdough discard loaf is how quickly it comes together, making it perfect for a weeknight bake or a weekend project that doesn’t eat up your whole day.
- Prep Time: 15 minutes
- Proofing Time: 45-60 minutes
- Bake Time: 25-30 minutes

Easy Variations And Serving Ideas That Fit Real Life
This soft sourdough loaf is incredibly versatile and can be adapted to suit your family’s preferences or different meal occasions.
For a savory twist, consider adding 1/2 cup of shredded cheddar cheese or a tablespoon of dried herbs like rosemary or oregano to the dough during the kneading stage. This makes a fantastic accompaniment to soups or stews. If you want a slightly sweeter bread, you could increase the sugar to 3 tablespoons and add a teaspoon of cinnamon, perfect for toast with butter and jam.
These sandwich squares are, of course, ideal for classic sandwiches with deli meat, cheese, and your favorite veggies. But don’t stop there! Cut them into smaller squares or even triangles for a delightful appetizer alongside a cheese board or with a simple dip like hummus or spinach dip. They make excellent mini grilled cheese sandwiches for kids, or you can toast them and serve with avocado and a sprinkle of everything bagel seasoning for a quick breakfast. For a party or buffet, slice the loaf thinly and serve with various spreads and toppings for guests to assemble their own bites.
Common Slip-Ups And How To Avoid Them
Even simple recipes can have their pitfalls. Knowing what to watch out for can help you achieve perfect results every time.
One common mistake is using water that’s too hot or too cold. Water that’s too hot can kill the yeast, preventing your bread from rising. Too cold, and the yeast won’t activate properly, leading to a dense loaf. Aim for warm bathwater temperature (100-110°F). Use a thermometer if you’re unsure.
Another common issue is over-flouring during kneading. While you need some flour to prevent sticking, adding too much will result in a dry, tough loaf. Add flour sparingly, just enough to make the dough manageable, and rely on kneading to develop its elasticity. The dough should still feel slightly tacky, not dry.
Not letting the dough rise enough is another frequent error. Rushing the proofing process will lead to a dense, heavy bread. Ensure your dough has nearly doubled in size for the first rise and risen significantly above the pan for the second. A warm, draft-free spot is key. If your kitchen is cold, try placing the bowl in a slightly warm (but turned off) oven with the light on.
Finally, slicing the bread before it’s fully cooled can compromise its texture. Hot bread is still cooking internally, and slicing it too soon can make it gummy or cause it to collapse. Patience is a virtue here; let it cool completely on a wire rack for at least an hour.
How To Store It And Make It Ahead Without Ruining Texture
Proper storage is key to keeping your homemade sourdough discard loaf fresh and delicious. Once completely cooled, store the bread in an airtight container or a large resealable plastic bag at room temperature. It will stay fresh for 3-4 days. Avoid refrigerating homemade bread, as it tends to dry out and become stale more quickly.
For longer storage, this bread freezes beautifully. Once cooled, slice the loaf into your desired sandwich squares or slices. Place the slices in a single layer on a baking sheet and freeze for about an hour until firm. Then, transfer the frozen slices to a freezer-safe bag or container, removing as much air as possible. It will keep well in the freezer for up to 3 months. When you’re ready to enjoy
