The Softest Sourdough Sandwich Bread You’ll Ever Bake (And It’s Viral!)
This recipe has gone viral on social media, with over 1.5 million views, and I get messages every day from people who love how easy and foolproof it is. Whether you’re a beginner or a seasoned baker, this method—using two loaf pans—helps create the softest, fluffiest sourdough bread you’ll ever make!
Why You’ll Love This Recipe
- Beginner-friendly: Simple steps and pantry ingredients make this approachable for new bakers.
- Same Day or Overnight recipe: No need to wait 24+ hours for your bread.
- Soft & fluffy: The two-pan method locks in moisture, creating a tender crust.
- Customizable: Add inclusions inside or on top for different flavors.
How to Make Soft Sourdough Sandwich Bread
Step 1: Mix the Dough
In a large mixing bowl, whisk together 150g active sourdough starter, 325g warm filtered water, 20g avocado oil (or cooled melted butter/olive oil), and 25g honey until combined. Stir in 500g unbleached flour and 10g salt until a shaggy dough forms. Cover and let it rest for 1 hour.
Step 2: Stretch & Fold
Perform four sets of stretch and folds every 30 minutes to build structure in the dough. This helps develop the gluten for a soft yet structured loaf.
Step 3: Bulk Ferment
Cover and let the dough continue to bulk ferment at room temperature for 4–8 hours (or overnight if your home is cooler). Bulk Fermentation times depend on your dough temperature. If your house/dough is warmer it will ferment faster. If it’s cooler, it will ferment slower. You’ll know it’s ready when it’s doubled in size, bubbly, and airy.
Step 4: Shape the Dough
Gently shape the dough into a loaf by stretching it into a rectangle, folding in the right side to the middle, then the left side into the middle, and rolling upward into a log. I also show this technique in my video below. Place it seam-side down in a well greased loaf pan.
Step 5: Second Rise–Proof
Now it’s time for the second rise. You have two options:
- Same day option: Let it proof at room temperature for 2 more hours before baking.
- Overnight cold proof: Let it cold proof in the refrigerator overnight or up to 24hrs.
Step 6: Bake
- Preheat oven to 400°F (200°C).
- Score the top of the dough and spray it lightly with water.
- Cover with an inverted second loaf pan (or loosely greased foil) to trap steam for the softest loaf. The inverted loaf pan method is shown below.
- Bake for 30 minutes at 400°F, then uncover and bake for 15 minutes at 375°F.
Step 7: Check for Doneness
Use a digital thermometer—your bread is fully baked when the internal temperature reaches 205°F (96°C).
Step 8: Cool & Enjoy!
Remove from the pan immediately and let it cool completely before slicing. This helps set the crumb and keeps it soft
How to store:
To keep my sourdough fresh, I store it in these sandwich bags from Amazon, which come with twist ties and mimic traditional storage methods. I usually keep the loaf on the counter for up to 2 days, then slice and freeze any leftovers. Sourdough freezes exceptionally well—just thaw slices as needed for fresh-tasting bread anytime!
Make It Your Own!
Feel free to experiment by adding mix-ins like cheese, seeds, or herbs. This soft sourdough sandwich bread is perfect for sandwiches, toast, or just enjoying with butter!
