Sourdough sandwich bread combines the tangy complexity of natural fermentation with the soft, fluffy texture ideal for everyday sandwiches. Originating from the ancient tradition of slow-leavened bread, sourdough has stood the test of time thanks to its health benefits, rich flavor, and unique texture.
Unlike artisan sourdough loaves with thick crusts and open crumbs, this recipe yields a tender, sliceable loaf—perfect for toast, grilled cheese, or deli-style sandwiches. Its mellow sourness, golden crust, and pillow-soft interior make it a go-to for families and sourdough enthusiasts alike.
Ingredients
Main Ingredients
-
1 cup (240g) active sourdough starter (100% hydration)
-
3 ½ cups (420g) bread flour
-
1 cup (240ml) whole milk (or any plant-based milk)
-
2 tbsp (30g) unsalted butter, softened (or olive oil for dairy-free)
-
1 tbsp (15g) honey or maple syrup
-
1 ½ tsp (9g) salt
Substitutions

Step-by-Step Cooking Instructions
1. Mix the Dough
-
In a large bowl, combine the sourdough starter, milk, butter, and honey.
-
Add flour and salt gradually, mixing until a sticky dough forms.
2. Bulk Fermentation (First Rise)
-
Cover the bowl with a damp towel and let it rise at room temperature for 4–6 hours, performing 3–4 stretch-and-folds every 30–45 minutes during the first 2 hours.
-
Dough should become smooth and slightly elastic.
3. Shape the Dough
-
Turn dough onto a lightly floured surface.
-
Shape it into a tight log, tucking the edges underneath.
4. Final Proof
-
Place the dough into a greased loaf pan.
-
Cover and proof for 8–12 hours in the fridge (or 2–3 hours at room temp) until it rises just above the rim.
5. Bake
-
Preheat oven to 375°F (190°C).
-
Bake for 35–40 minutes, or until golden brown and internal temperature reaches 200°F (93°C).
-
Let cool on a wire rack before slicing.
Common Mistakes to Avoid
-
Overproofing: This can cause the bread to collapse while baking.
-
Skipping stretch-and-folds: These develop gluten for a strong structure.
-
Slicing too soon: Let it cool fully or the crumb may become gummy.
Pro Tips and Cooking Techniques
-
Use a pullman loaf pan for a perfect sandwich-bread shape.
-
Add a pan of water to the oven to create steam for a better crust.

Butter the top right after baking for a softer crust.
