Bake Time: 40–45 minutes
Cooling Time: 1 hour
Total Time: About 10–12 hours (mostly hands-off)

Yield: 1 loaf (12–14 slices)

Ingredients

Dough

500g (4 cups) bread flour
100g (½ cup) active sourdough starter (100% hydration)
300ml (1¼ cups) warm water
30g (2 tablespoons) honey
30g (2 tablespoons) unsalted butter, softened
10g (2 teaspoons) fine sea salt

Optional Egg Wash

1 egg
1 tablespoon milk

Optional Topping

Rolled oats
Sesame seeds
Poppy seeds

Equipment Needed

Large mixing bowl
Kitchen scale
Stand mixer (optional)
Dough scraper
9×5-inch loaf pan
Plastic wrap or kitchen towel
Cooling rack
Instant-read thermometer

Step 1: Feed Your Starter

Use a healthy, active sourdough starter that has been fed 4–8 hours before baking and has doubled in size.

A bubbly, active starter ensures the best rise and flavor.

Step 2: Mix the Dough

In a large mixing bowl, combine:

Active sourdough starter
Warm water
Honey

Stir until combined.

Add the bread flour and mix until no dry flour remains.

Let the dough rest for 30 minutes (autolyse).

After resting, add the softened butter and salt.

Knead by hand for 10–12 minutes, or with a stand mixer for 8–10 minutes, until the dough is smooth, elastic, and slightly tacky.

Step 3: Bulk Fermentation

Transfer the dough to a lightly greased bowl.

Cover and let rise at 72–75°F (22–24°C) for 6–8 hours.

Perform 3–4 stretch-and-folds during the first 2 hours, spacing them about 30 minutes apart. To do this, gently lift one side of the dough, stretch it upward, and fold it over the center. Rotate the bowl and repeat on all four sides. These folds strengthen the dough and help create a light, even crumb without intensive kneading.

The dough is ready when it has increased by about 50–75% in volume and feels airy.

Step 4: Shape the Loaf

Turn the dough onto a lightly floured surface.

Gently press it into a rectangle about the width of your loaf pan.

Roll the dough tightly into a log, pinching the seam closed after each turn.

Tuck the ends underneath to create a smooth shape.

Place the loaf seam-side down into a lightly greased 9×5-inch loaf pan.

Step 5: Second Rise

Cover the loaf loosely with plastic wrap or a kitchen towel.

Allow it to rise for 2–3 hours, or until the dough rises about 1 inch (2.5 cm) above the rim of the pan.

For a deeper sourdough flavor, refrigerate the shaped loaf overnight after about 30–60 minutes of room-temperature proofing. Bake it straight from the refrigerator the next day.

Step 6: Preheat the Oven

Preheat the oven to 375°F (190°C).

If using an egg wash, whisk together the egg and milk, then gently brush the top of the loaf.

Sprinkle with oats or seeds if desired.

Step 7: Bake

Bake for 40–45 minutes, or until the loaf is deep golden brown.

If the top browns too quickly, loosely cover it with aluminum foil during the last 10–15 minutes of baking.

The bread is fully baked when the internal temperature reaches 200–205°F (93–96°C).

Step 8: Cool

Remove the bread from the pan immediately after baking.

Place it on a wire rack and cool for at least 1 hour before slicing.

Cooling allows the crumb to finish setting and helps prevent gummy slices.

Expert Tips

Use an Active Starter

A lively starter that has recently doubled in size will produce the best rise and flavor.

Weigh Ingredients

Using a digital kitchen scale ensures consistent hydration and texture.

Don’t Rush the Fermentation

Sourdough develops its flavor over time. Allow the dough to ferment until it is airy rather than watching the clock alone.

Shape Tightly

A snug roll creates an even crumb and a tall sandwich loaf.

Cool Before Slicing

Resist cutting into the loaf while it’s hot. Cooling completely gives cleaner slices and better texture.

Delicious Variations

Honey Oat Sourdough

Mix ½ cup rolled oats into the dough and sprinkle additional oats on top before baking.

Whole Wheat Sourdough Sandwich Bread

Replace up to 30% of the bread flour with whole wheat flour for a nuttier flavor while maintaining a soft crumb.

Seeded Sourdough Loaf

Add sunflower seeds, flaxseeds, sesame seeds, and pumpkin seeds to the dough for extra texture and nutrition.

Herb and Garlic Sandwich Bread

Mix in 1 tablespoon chopped fresh rosemary, thyme, or parsley along with 2 teaspoons garlic powder.

Cheese Sourdough Loaf

Fold in 1 cup shredded cheddar, mozzarella, or Gruyère during the final minutes of mixing.

Cinnamon Raisin Sourdough

Add 1 teaspoon ground cinnamon and ¾ cup raisins for a lightly sweet breakfast loaf.

Make-Ahead Instructions

After shaping the loaf, cover it tightly and refrigerate overnight.

Bake directly from the refrigerator the next morning, adding 5–10 minutes to the baking time if needed.

Freezing Instructions

Whole Loaf

Allow the bread to cool completely.

Wrap tightly in plastic wrap followed by aluminum foil.

Freeze for up to 3 months.

Sliced Bread

Slice the loaf before freezing.

Place parchment paper between slices and store in a freezer-safe bag.

Toast individual slices directly from frozen.

Storage

Room Temperature: Store in a bread bag or airtight container for up to 4 days.
Refrigerator: Not recommended, as refrigeration can dry out the bread more quickly.
Freezer: Up to 3 months.

To refresh the loaf, warm slices in a toaster or heat the whole loaf in a 325°F (163°C) oven for 8–10 minutes.

Frequently Asked Questions

Can I use all-purpose flour?

Yes, but bread flour is preferred because its higher protein content creates a stronger gluten structure and a softer, taller loaf.

Why didn’t my loaf rise much?

The most common reasons are an inactive starter, cool room temperature, or insufficient fermentation time. Make sure your starter is bubbly and doubles after feeding.

Do I need a loaf pan?

For a classic sandwich loaf with straight sides, a loaf pan is recommended. Free-form baking will produce a more rustic shape.

Can I add commercial yeast?

You can add 1 teaspoon instant yeast if you’re short on time, but doing so will reduce the distinctive sourdough flavor and natural fermentation benefits.

Why is my bread gummy?

A gummy texture usually means the loaf was underbaked or sliced before it had fully cooled. Always check for an internal temperature of 200–205°F (93–96°C) and let the bread cool completely before cutting.
