This soft sourdough sandwich bread is fluffy, tender, and naturally fermented for flavor and gut health. A bakery-style loaf that’s perfect for toast, sandwiches, and meal prep.

Ingredients

  • 1/2 cup (115g) active sourdough starter (100% hydration)
  • 1 cup (240g) warm whole milk
  • 2 3/4 cups (330g) bread flour (or a 50/50 mix with all-purpose flour)
  • 2 tbsp (30g) unsalted butter, softened
  • 1 tbsp (20g) honey or sugar
  • 1 tsp (6g) fine sea salt

Instructions

  1. In a large bowl, mix warm milk, sourdough starter, and honey.
  2. Add flour and stir until a shaggy dough forms. Rest for 30 minutes.
  3. Add salt and softened butter. Knead until smooth and elastic.
  4. Place dough in a greased bowl. Cover and ferment at room temp for 4–6 hours, stretching and folding every hour.
  5. Shape into a loaf and place into a greased 8.5×4.5-inch pan.
  6. Cover and let proof at room temp for 3–5 hours, or overnight in the fridge.
  7. Preheat oven to 375°F. Place a tray of boiling water in the bottom rack for steam.
  8. Bake the loaf for 35–40 minutes or until golden and internal temp is 190°F–200°F.
  9. Brush with melted butter and cool for 1 hour before slicing.

Notes

  • Use high-protein bread flour for better rise and structure
  • For deeper flavor, use the cold-proof method (refrigerate shaped dough overnight)
  • Optional: Add 1 tbsp milk powder to enrich the dough even more
  • This recipe works well with 20% whole wheat flour substitution
