Introduction
There is something incredibly satisfying about baking a beautiful loaf of homemade bread. My kitchen often smells of freshly baked goods, and this sourdough discard bread is a particular favorite.
It offers all the joy of real food made from scratch, providing a wonderful way to transform your sourdough discard into a delicious pantry staple.
This recipe will guide you to a soft, fluffy sandwich loaf with a subtle sourdough tang, making it perfect for both seasoned bakers and newcomers alike.
Why You’ll Love This Recipe
My unique twist on this sourdough discard bread recipe truly elevates it to another level. We are embracing an egg wash and an extended cold proof for 8-12 hours in the refrigerator. This specific technique brings profound benefits to your final loaf.
Deeper, more complex sourdough flavor. The cold proofing significantly slows the yeast’s activity, while allowing the acetic and lactic acid bacteria from the sourdough discard to become more active.
This extended cold fermentation truly develops a richer, more complex sourdough flavor profile, delivering that desirable tang.
Superior texture is a hallmark of this bread. The cold proof strengthens the gluten structure. This results in a finer, softer crumb and a crispier, more caramelized crust. This is due to increased enzymatic activity breaking down starches into sugars on the surface, which aids in the Maillard reaction during baking.
Unbeatable convenience also comes with this method. The cold proof offers incredible scheduling flexibility for busy home bakers. You can prepare the dough one day and bake it fresh the next, fitting bread making into your life with ease.
This recipe is an easy and rewarding process, even for beginners. It makes perfect sandwich bread for the whole family to enjoy. Plus, it is a fantastic way to utilize your sourdough discard instead of letting it go to waste.
Ingredients Needed

- 1 cup water
- 1 tablespoon honey
- 3 teaspoons active dry yeast
- 4 tablespoons butter (softened)
- 4 cups all purpose flour
- 1/2 tablespoon salt
- 1 cup sourdough discard
Ingredient Notes & Substitutions
Sourdough Discard. This recipe uses sourdough discard, which is unfed and less active starter, primarily for its incredible flavor contribution. While you could technically use active sourdough starter, the discard gives a specific texture and flavor profile we are aiming for here.
Butter. For the best incorporation, ensure your butter is truly softened. If you need a dairy-free option, you can easily substitute avocado oil or olive oil for the butter.
Honey. I love the subtle sweetness and moisture that honey adds. However, if you prefer, granulated sugar can be swapped in place of the honey.
Flour. All-purpose flour is my go-to for this soft sandwich bread, giving it a wonderfully tender crumb. If you desire a slightly chewier texture, you could use bread flour, which has a higher protein content.
Yeast. While we are using sourdough discard for flavor, the active dry yeast is crucial here for a reliable and consistent rise. It ensures your loaf is light and fluffy every time.

How to Make Sourdough Discard Bread
Activate the Yeast
To begin, whisk together warm water, honey, and active dry yeast in a small bowl. Allow this mixture to sit at room temperature for about 5 minutes. You should see it become nicely bubbly, which indicates your yeast is active and ready to work. It is crucial to avoid water that is too hot, as this will kill the yeast and prevent your bread from rising.
Combine Dough Ingredients
Next, in the bowl of a stand mixer fitted with a dough hook attachment, add the activated yeast mixture. Then, incorporate the softened butter, all-purpose flour, salt, and sourdough discard.
Knead for Gluten Development
With your stand mixer, knead the dough on low speed for about 10 minutes or so. The goal is for the dough to become smooth and elastic, and it should no longer stick to the sides of the bowl. If you are kneading by hand, this process might take a bit longer. To ensure proper gluten development and guarantee a nice and fluffy bread, perform the windowpane test. Grab a small ball of the dough and gently stretch it into a square. It should stretch thin enough that you can see through it without the dough breaking.
Bulk Rise (First Proof)
Once kneaded, place the dough into a lightly greased bowl. Cover the bowl with a lid, plastic wrap, or a clean towel. Let the dough rise, also known as the bulk rise, for about 1-2 hours, or until it roughly doubles in size. A warm environment, like on top of a stove or refrigerator, can help encourage an optimal rise. Be mindful not to over-ferment the dough, as this can lead to a less desirable texture.
Prepare Loaf Pan
While your dough is on its first rise, prepare your loaf pan. Grease a standard loaf pan thoroughly, or line it with parchment paper for easy removal.
Shape the Dough
Once the bulk rise is complete, gently punch down the dough to release the air. On a lightly floured surface, roll the dough flat into a rectangle. Then, roll it up tightly from one of the longer sides. Pinch the ends firmly to the rest of the loaf to create a neat, secure shape.
Second Rise & The Cold Proof Twist
Carefully place the shaped bread dough into your prepared loaf pan, seam side down. Allow it to undergo a second rise for 30 minutes to an hour at room temperature, or until it has doubled in size. Keep it covered with a towel during this time. Now for our unique twist: if desired, whisk an egg in a small bowl and brush it evenly on top of the dough. Then, cold proof the loaf in the refrigerator for 8-12 hours. This extended cold proof strengthens the gluten, deepens the sourdough tang, and helps create an incredible crust.
Bake
After the cold proof, preheat your oven to 375 degrees F. Bake the sandwich loaf for about 45 minutes, or until it achieves a lovely golden brown color on top. To confirm doneness, I always recommend checking for an internal temperature between 195-210 degrees F with an instant-read thermometer.
Cool Completely
This step is crucial for the final texture. Allow the bread to cool completely on a wire rack before attempting to slice or store it. This ensures the crumb sets properly and prevents a gummy texture.
Achieving Bakery-Quality Sourdough Discard Bread
Choosing Your Loaf Pan & Preparing It
For this sourdough discard bread, I highly recommend using a standard 9×5 inch loaf pan. Metal pans tend to give a very even browning, while glass pans retain heat effectively. You can choose to grease your pan thoroughly, or for even easier release, I often line mine with parchment paper, leaving an overhang on the sides to lift the loaf out effortlessly.
Understanding Sourdough Discard Stages
The stage of your sourdough discard can subtly influence the final crumb and flavor profile of your bread. Unfed discard, which is less active, tends to contribute a more pronounced tang and allows for a longer fermentation time, which is ideal for this recipe. Recently fed discard, while more active, might result in a less tangy flavor. Either can be used, but for that deep flavor, I prefer using unfed discard.
To Score or Not to Score?
While traditional sourdough loaves often benefit from scoring to guide oven spring and create beautiful patterns, a sandwich loaf like this, especially with our cold proof, does not strictly require a deep score for functionality. The egg wash and controlled rise help create an even crust. You can opt for a simple, shallow score down the center for a classic look, or leave it plain. It is mostly for visual appeal with this type of bread.
Flour Power: Optimizing for Texture
My recipe uses all-purpose flour for a wonderfully soft and tender crumb. However, if you are inclined to experiment with bread flour, which has a slightly higher protein content, you might notice the dough feeling a bit stiffer. Bread flour can absorb a little more water. If using bread flour, be prepared to potentially add a tablespoon or two more water if the dough seems too dry or stiff during kneading, ensuring optimal gluten development for that fluffy bread texture.
Pro Tips & Troubleshooting
Pro Tips for Success
Soft Butter is Key. Always ensure your butter is truly soft for smooth and even incorporation into the dough. This helps create a tender crumb.
Stand Mixer Efficiency. A stand mixer with a dough hook attachment makes the kneading process much easier and more consistent, ensuring excellent gluten development without a lot of manual effort.
The Windowpane Test. Do not skip the windowpane test. It is your best indicator that the gluten has developed sufficiently, which is essential for a light and fluffy crumb.
Warm Rising Environment. Find a consistently warm spot for your bulk rise. This encourages the yeast to work efficiently, leading to an optimal proof. My go-to spots are often on top of a warm oven or refrigerator.
Doneness Check. For perfect doneness, always check the internal temperature of your loaf. It should register between 195-210 degrees F.
Cool Completely. This is crucial. Allow your bread to cool completely on a wire rack before slicing or storage. This step sets the crumb and prevents a gummy texture.
Cold Proof Benefits. Remember, the cold proof is your secret weapon for deep flavor, an amazing crust, and improved gluten strength. Embrace the chill!
Common Mistakes to Avoid
Over-Fermenting Dough. Letting your dough over-ferment can lead to a wet, sloppy texture and a poor rise during baking. Watch for visual cues like the dough doubling in size, rather than just relying on time.
Too Hot Water for Yeast. Using water that is too hot will kill the active dry yeast, preventing your bread from rising altogether. Aim for lukewarm water, around 105-115 degrees F.
Insufficient Kneading. If your bread turns out dense and fails the windowpane test, it is likely due to insufficient kneading. Keep kneading for a few more minutes until it passes.
Rushing Rise Times. Patience is paramount in bread making. Rushing the resting and rising times will negatively impact the final texture and rise of your sourdough discard bread. Let the dough take its time.
Splitting Crust. If your bread splits on one side during baking, it can sometimes be due to uneven oven spring. Our cold proof method, combined with the egg wash, helps create a strong, even surface that resists splitting, resulting in a lovely, uniform crust.
Dense Crumb. A dense crumb often points to either insufficient kneading (poor gluten development) or over-fermentation. Refer back to the windowpane test and visual cues for proper rising.
Serving & Storage
Serving Ideas
This versatile sourdough discard bread makes the most incredible classic sandwich bread for everyday lunches. It is also phenomenal for preparing French toast or gourmet grilled cheese sandwiches. Simply toasted with butter and your favorite jam, it is a delightful breakfast treat. You can also elevate it as an ingredient for savory bread puddings, homemade croutons, or served alongside hearty soups and stews for a comforting meal.
Storage and Make-Ahead
To store your sourdough discard bread for short-term freshness, keep it in a bread box or a sealed plastic bag on the counter for 2-3 days. For longer storage, this bread freezes beautifully. I recommend slicing the bread first, placing a small piece of parchment paper between each slice, and then freezing the slices in an airtight freezer bag. You can then thaw slices as needed for toast or sandwiches.
Slicing a Soft Loaf. A very soft loaf can be tricky to slice cleanly. My best tip is to ensure the loaf is completely cooled before you even think about cutting into it. Ideally, let it cool for several hours, or even slightly chill it in the refrigerator. Use a very sharp serrated knife and saw gently rather than pressing down.

FAQ
What is the key difference between sourdough bread and sourdough discard bread?
The key difference lies in leavening. Traditional sourdough bread relies solely on a vibrant sourdough starter for its rise, using wild yeast and bacteria. Sourdough discard bread, while gaining wonderful flavor from the discard, primarily uses commercial yeast, like active dry yeast, for a reliable and predictable rise. This results in a controlled tang and a typically softer crumb.
Can I substitute active sourdough starter for discard in this recipe?
While technically possible, I strongly recommend sticking with sourdough discard for this particular recipe. An active sourdough starter has much more leavening power and might alter the final rise and the intended flavor profile, giving you a different result than what this recipe aims for.
What is the recommended loaf pan size for this sourdough discard sandwich bread?
For this recipe, a standard 9×5 inch loaf pan is highly recommended. This size ensures the ideal sandwich bread shape and allows for the perfect rise, giving you a beautifully proportioned loaf.
How should I store leftover sourdough discard sandwich bread?
To keep your homemade sourdough discard sandwich bread fresh, store it at room temperature in an airtight container or a bread bag for up to 2-3 days. For longer storage, slice the bread and freeze the slices with parchment paper in between. This allows you to thaw individual slices as needed, keeping the bread fresh for up to 3 months.
Why is the windowpane test important for achieving a fluffy bread texture?
The windowpane test is crucial because it confirms that your dough has developed enough gluten. Proper gluten development creates the elastic internal structure needed to trap the gases produced by the yeast, resulting in a light, airy, and fluffy crumb rather than a dense bread.
How can I ensure a smooth, even crust and prevent splitting during baking?
Achieving a smooth, even crust requires proper gluten development and careful shaping. Our unique twist, which includes an egg wash and an extended cold proof, significantly helps here. The cold proof strengthens the dough’s surface, while the egg wash promotes a crisper, more caramelized crust and helps prevent random splitting by providing a resilient surface during oven spring.
Are there any tricks for slicing a soft loaf of sourdough discard bread evenly?
Yes, there are definitely tricks for cleanly slicing a very soft loaf. First and foremost, the loaf absolutely must be cooled completely before you attempt to slice it. Warm bread compresses easily and can be very difficult to cut. Ideally, let it cool for several hours, or even chill it slightly in the refrigerator for an hour or so. Then, use a very sharp serrated knife and use a gentle sawing motion rather than pressing down.
What should I do if my dough doesn’t pass the windowpane test?
If your dough does not pass the windowpane test, simply continue kneading it for a few more minutes. Then, re-test it. Different flours or slight variations in hydration can affect kneading time. It is always better to slightly over-knead than to under-knead, as proper gluten development is essential for achieving that fluffy bread outcome.
