Preparing this Super Soft Sourdough Sandwich Bread Recipe

Whipping up this soft sourdough sandwich bread requires you to plan ahead a bit. The bulk fermentation stage takes upwards of 12 hours, so plan accordingly!

  • Make the Dough: In a large mixing bowl, whisk the water, sourdough starter, and sugar together until dissolved. Add in the flour and salt, cover the dough with plastic wrap, and let it rest for 30 minutes.
  • Let the Dough Rest: Stretch and fold the dough, cover it with plastic wrap, and let it rest at room temperature for 12 hours.
  • Divide the Dough: Separate the dough into two equal parts and shape them into rectangles. Press down on the dough with your fingers to get rid of air bubbles.
  • Shape the Dough: Roll the dough into a log and place it into a greased loaf pan. Repeat with second half of dough. Allow loaves to rise for an hour.
  • Bake the Bread: Bake the bread at 375°F for 45 minutes. Remove the pans from the oven and brush the tops with butter.
  • Allow the Bread to Rest: Let the loaves rest for 5 minutes and move them to a wire rack and let them rest for 30 minutes before slicing in. Now it’s time to whip up your favorite sandwich!

Tips for Making the Perfect Sourdough Sandwich Loaf

To really nail the texture and taste of your sourdough slices, follow these simple tips from our kitchen to yours.

  • Use an active starter. For this recipe, you need to make sure that your starter is active. This means that you need to feed the starter about 10-12 hours before using it. If you don’t feed your starter, your bread will turn out dense.
  • Know that the dough will be sticky. The dough should be sticky – don’t panic! Make sure you handle it on a well-floured surface and you’ll be golden.
  • Make sure your bread pans are well-greased. Spray your pans with cooking spray oil or coat it generously with butter softened at room temperature. If you don’t, the loaves will stick to the pans and fall apart. Here is a guide on our favorite oils to use.
  • Different sized pans will affect the baking time. Depending on what size of pan you use, you’ll have to adjust the baking time accordingly. Larger pans will make the bread cook faster, while smaller and taller pans will cause it to cook slower.
  • The flour you use makes all the difference. Depending on the brand of flour you use, you may need to extend the baking time. Opt for high-protein flour like Bob’s Red Mill Bread Flour for the best taste and texture.
  • Allow the bread to rest before slicing into it. Give the bread at least 30 minutes to rest on the cooling rack before you attempt to slice into it. This will give it time to firm up so you don’t smash it while it’s still hot. Also, use a serrated knife to get those perfect slices your looking for.

How to Store Sourdough Sandwich Bread

To keep your sourdough bread as fresh as possible here’s all you need to know about storing it properly.

  • Room Temperature: To keep the bread on hand for up to a week, store it in a bread box or airtight container on the counter. This will prevent it from becoming stale.
  • Refrigerator: To extend the life of your bread to a couple of weeks, store it in a plastic storage bag in the refrigerator. Of note, bread tends to get a little dry in the cold air of the fridge, so make sure to seal the bag tightly.
  • Freezer: To keep the bread on hand for up to three months, freeze it. Allow it to cool down completely, wrap it in plastic wrap, and stuff it into a freezer-safe plastic bag. To thaw the bread, place it in the fridge overnight or leave it on the counter for a couple of hours.

Hot Tip: Keep in mind that during the summer months bread can get moldy much quicker.
