Ingredients

For the Dough

  • 500g bread flour
  • 350g water, room temperature
  • 100g active sourdough starter
  • 10g salt
  • 20g honey or maple syrup
  • 20g unsalted butter, softened

Optional Topping

  • Melted butter for brushing after baking

Equipment Needed

  • Large mixing bowl
  • Kitchen scale
  • Dough scraper
  • Loaf pan (9 x 5 inch)
  • Clean kitchen towel
  • Cooling rack

Instructions

Step 1: Mix the Dough

In a large mixing bowl, combine the active sourdough starter and water. Stir until the starter dissolves completely.

Add the bread flour and mix until no dry flour remains. Cover the bowl and allow the dough to rest for 30 minutes. This resting period, known as autolyse, helps develop gluten and improves dough structure.

After resting, add the salt, honey, and softened butter. Mix thoroughly until all ingredients are fully incorporated.

Step 2: Strengthen the Dough

Perform a series of stretch-and-folds every 30 minutes for the first 2 hours.

To do this:

  1. Wet your hands.
  2. Grab one side of the dough.
  3. Stretch it upward.
  4. Fold it over itself.
  5. Rotate the bowl and repeat on all four sides.

Complete four rounds of stretch-and-folds.

The dough will gradually become smoother and stronger.

Step 3: Bulk Fermentation

Cover the bowl and allow the dough to ferment at room temperature for 4–6 additional hours.

The dough should rise by approximately 50–75% and appear airy with visible bubbles along the sides.

Fermentation time may vary depending on the temperature of your kitchen and the strength of your starter.

Step 4: Shape the Dough

Lightly flour your work surface.

Turn the dough out onto the counter and gently press it into a rectangle.

Fold the left and right sides toward the center, then roll the dough tightly into a log shape.

Place the shaped dough seam-side down into a lightly greased loaf pan.

Step 5: Final Proof

Cover the loaf pan with a towel or plastic wrap.

Allow the dough to rise for 2–3 hours at room temperature until it has expanded noticeably and reaches about 1 inch above the rim of the pan.

For deeper flavor, you can refrigerate the loaf overnight and bake the next day.

Step 6: Bake

Preheat your oven to 375°F (190°C).

Place the loaf pan in the center of the oven.

Bake for 35–40 minutes, or until the top is golden brown and the internal temperature reaches 200°F (93°C).

If the top begins browning too quickly, loosely tent it with aluminum foil during the final 10 minutes of baking.

Step 7: Cool

Remove the loaf from the oven and allow it to rest in the pan for 10 minutes.

Transfer the bread to a wire rack and cool completely before slicing.

Brushing the top with melted butter while warm will create a softer crust and add extra flavor.


Tips for Success

  • Use a highly active sourdough starter that has doubled in size before mixing the dough.
  • Measure ingredients by weight for consistent results.
  • Avoid slicing warm bread, as it can become gummy inside.
  • If your kitchen is cold, fermentation may take longer.
  • Store the loaf in a bread bag or airtight container to maintain freshness.

Serving Suggestions

This sourdough sandwich loaf is perfect for:

  • Grilled cheese sandwiches
  • Breakfast toast
  • Peanut butter and jelly sandwiches
  • French toast
  • Avocado toast
  • Homemade croutons

Its soft texture and mild tang make it versatile enough for both sweet and savory toppings.

Room Temperature

Store in an airtight container for up to 4 days.

Freezer

Slice the loaf before freezing. Store in a freezer-safe bag for up to 3 months.

Thaw slices individually or toast directly from frozen.


Frequently Asked Questions

Can I use all-purpose flour?

Yes. However, bread flour produces a stronger gluten structure and a better rise.

Why didn’t my loaf rise enough?

The most common causes are an inactive starter, insufficient fermentation time, or a cool room temperature.

Can I make this recipe without butter?

Yes. You can substitute olive oil or omit the fat entirely, though the loaf may be slightly less soft.

How do I know when the bread is fully baked?

The internal temperature should reach 200–205°F (93–96°C) when measured with an instant-read thermometer.
