This Sourdough Sandwich Bread recipe is fluffy and hearty. It is a yeasted loaf bread that uses either sourdough discard, leaven, or faux starter for flavoring. It can be made with varying percentages of whole wheat flour for extra substance.
What is a Leaven?
A leaven is a mixture of water, all-purpose flour, and sourdough starter that goes into bread dough for a sourdough recipe. Basically, it is a blend of flour and water that becomes a bread leavener through the process of fermentation. In the case of this recipe, the leaven ferments on the counter for 6 to 12 hours. So be sure to start it well before you are ready to bake your bread.
You will know that it is ready to use in your bread dough when it is slightly sour-smelling and bubbly. For those who enjoy a less sour taste in their bread, go for a shorter amount of time. People who love really tangy sourdough, however, may prefer to let the leaven sit for the full 12 hours.
A starter is a blend of all-purpose flour and water that sits on a counter to activate the natural yeasts from the flour and also to collect additional yeasts from the air and environment. The starter requires regular feedings of additional flour and water to ensure that those yeasts stay active and develop into something that is strong enough to raise bread dough.
However, at each feeding, the baker needs to discard a portion of the starter, as it is simply not needed. If you have plenty of discard (3/4 cups worth), you can use that to replace the leaven in this bread. It will give the loaf a delicious. strong and tangy sourdough flavour.
Sourdough recipes like this one or my Sourdough Biscuits an excellent place to use the sourdough discard. However, if you have a lot and really don’t want to get rid of it, you could place it in the freezer. Simply put it in a sealable container to freeze. When it is thawed, you can use it in discard recipes. Otherwise, it will need a few daily feedings to activate it again.
Even if you don’t have any starter around, you can still make this sourdough recipe. My friend Lorena taught me another way to make a starter in her Artisan Bread Recipe. To avoid confusion with the other mentions of starter and leaven in this post, I am calling that one faux-starter.
For faux-starter, you also make a leaven the night before baking, but instead of 1 tablespoon of sourdough starter, 1/2 packet of yeast is used. The yeast gets mixed with the flour and water like the sourdough starter would have and sits overnight to ferment into a bubbly, tangy mixture. This process makes for a more flavourful bread than omitting starter altogether. It just might not result in quite as tangy a loaf as when it uses sourdough discard or starter.
Making bread at home can be time-consuming, however, most of the time is hands-off. The dough undergoes two rises. The dough rises for the first time in a bowl after kneading, while the second rise happens in the loaf pan after shaping.
The first rise is part of the autolyse process, which is where protease and autolyse enzymes start to work. Basically, the protease enzymes break down the protein in the flour, whereas the autolyse enzymes make the sugars in the flour more accessible to yeast.
Proofing Dough in the Instant Pot
You can use your electric pressure cooker like the Instant Pot on the Yogurt setting to speed up the first rise. The moderately warm temperature needed for yogurt incubation also creates the perfect environment in your Instant Pot for proofing dough.
Simply grease the inner liner, add the dough and close with a lid. I am using a glass lid, so I can watch the dough and see when it has doubled. Using the Instant Pot reduces the rising time from a minimum of 45 mins (at room temperature) down to 20 to 30 minutes.
The second rise helps with the structure of the bread. After shaping a bread dough, a lot of the air bubbles that the yeast created are pushed out of the dough. By letting the dough sit in the pan, it has the chance for the yeast to work again – producing more air and bubbles in the dough.
This helps the bread form a finer, fluffier crumb than it would have otherwise. This step is also called proofing and is the last thing the bread needs to do before baking.
How to shape the dough
Shaping the dough properly is important for a proper bread structure. Shaping a bread correctly means that it should rise in a uniform way during baking. Also, it will ensure that the bread has a smooth top once it is baked.
The process is relatively simple. After the first rise, turn out the dough on the counter and gently stretch it out by hand. Next, fold in one-third of the dough from the right towards the center, followed by one-third from the left. Now, roll up the dough tightly from the bottom and slightly tuck in the ends. Then you can put the sandwich loaf in your prepared loaf pan and let the dough rise for a second time before baking.
If desired, you can jazz up your sourdough bread with some toppings as a garnish. I like to add a mixture of seeds (flax + sesame) and rolled oats. Other options are sunflower seeds, poppy seeds, caraway, hemp, pumpkin seeds, millet, and more. These not only make the loaf look even more attractive and delicious but also add some hearty nutrition in the form of fiber and healthy fats.
When adding toppings to your bread, be sure to brush the top of the dough with water in order to help the seeds and/or oats stick. Otherwise, the seeds won’t adhere during baking as the exterior becomes crispy.
Storing Sandwich Bread
While bread is delicious out of the oven, it can dry out quite quickly. Simply cover it tightly to protect it from drying out. You can wrap it tightly with foil, place it in a sealable bag or in a large airtight container. It should be able to keep at room temperature for several days like this.
If your bread does dry out too much to enjoy fresh, you don’t have to throw it away unless it has turned moldy. Instead, toast it for breakfast or thinly slice or cut into cubes for crostini or croutons. Alternatively, you could use this stale bread in a bread pudding to give it new life.
Freezing Sourdough Sandwich Bread
For longer storage, slice the entire sourdough loaf once it has fully cooled. Then, place the slices in an airtight freezer-safe container or bag. To use, take out only as many slices as needed. Defrost at room temperature (only takes a few minutes) or toast for that freshly baked taste.

Sourdough Sandwich Bread
This Sourdough Sandwich Bread is fluffy and hearty. It is a yeasted loaf bread that uses either sourdough discard, leaven, or faux starter for flavoring. It can be made with varying percentages of whole wheat flour for extra substance.
- 200 grams (3/4 cup) sourdough discard
Or make Leaven the night before:
- 100 grams (7/8 cup) flour I use half all-purpose, half whole wheat
- 100 grams (1/3 cup) filtered water
- 25 grams (heaping tablespoon) sourdough starter or 3.5 g instant yeast (1/2 packet)
- 177 grams (3/4 cup) filtered water add more if needed to make a smooth dough
- 40 grams (2 tablespoons) honey or maple syrup
- 21 grams (2 tablespoons) olive oil or avocado oil
- 1/2 packet (3.5 grams or 3/4 teaspoon) instant yeast
- 320 grams (2.5 cups) all-purpose flour
- 113 grams (7/8 cup) whole wheat flour or use up to 50% ww flour (makes a denser loaf)
- 14 grams (2 tablespoons) flax meal
- 10 grams (2 teaspoons) sea salt
- toppings like sesame, flax, or oats
If you don't have sourdough discard to use up, make a leaven the night before. Stir together flour, water, and a tablespoon of sourdough starter (or instant yeast). Cover and let sit overnight (6-12 hours).
In the morning, dissolve the sourdough discard or leaven in 2/3 cup of water. Then stir in the honey, oil and instant yeast.
To a large bowl add the both types of flour, flax meal, and sea salt. Pour the liquid ingredients over top and start to mix everything together in the bowl.
Once the bread dough starts to form, turn it out on a floured surface. Knead the dough for about 15 minutes by hand until stretchy and elastic. Alternatively, you can use a stand mixer with dough hook for about 5 minutes.
Add the dough ball to an oiled bowl. Cover and let rise until doubled for about 45 minutes. Or let the bread dough rise in the oiled inner liner of your Instant Pot on the Yogurt setting until doubled (20-25 minutes).
Grease a loaf tin with a little oil.
After rising, turn the dough out on the counter. Flatten gently, then fold over 1/3 from the right, then 1/3 from the left. Now roll the dough up tightly from the bottom to form a loaf shape. Tuck under the ends slightly.
Place the dough loaf in the greased tin. Cover the loaf and let rise for 1 hour.
Preheat the oven to 350°F (190°C). If desired, brush the risen loaf top with water and sprinkle seeds/oats all over. Make diagonal cuts across the top. Then place the loaf in the oven and bake for about 40 minutes until it looks golden brown and sounds hollow.
Unmold from the tin and let the sourdough sandwich bread cool completely (on a wire rack) before slicing.
To store the bread for longer than a couple of days, slice it, then freeze airtight. Toast the frozen slices as needed, for a freshly baked taste.
