The Soft Sourdough Sandwich Loaf

Most sourdough is rustic. Sometimes you need bread for sandwiches, toast, and grilled cheese — bread that slices clean, has a tight crumb, and fits in a Pullman pan.

Recipe — one 9×5 inch pan loaf

• 500g bread flour
• 300g milk, warmed (60%)
• 100g active starter (20%)
• 30g butter, melted (6%)
• 25g honey or sugar (5%)
• 10g salt (2%)

Method

Mix

Combine warm milk, melted butter, honey, and starter. Stir.

Add flour and salt. Mix until shaggy.

Knead 5 minutes by hand or 4 minutes in a stand mixer with a dough hook. Should be smooth, soft, slightly tacky.

Bulk

Bulk 4–6 hours at 75°F, with 2–3 sets of folds in the first 90 minutes.

Shape

Tip dough onto a lightly floured counter.

Pre-shape into a loose ball. Bench rest 20 minutes.

Final shape: pat into a rectangle, fold the long sides into the middle (letter fold), then roll up tightly from one short end. Pinch the seam closed.

Place seam-side down in a buttered 9×5 inch loaf pan.

Final proof

Proof 1–3 hours at room temperature, or 8–12 hours in the fridge.

The dough should rise to about ½ inch above the pan rim and be visibly puffy.

Bake

Preheat oven to 425°F.

Brush the top of the loaf with milk or beaten egg for shine.

Bake 30–40 minutes until deeply golden. Internal temp 200°F.

If the top browns too fast, tent with foil after 20 minutes.

Cool

Remove from pan immediately. Cool on a rack 1 hour minimum before slicing.

What good sandwich bread is

• Tall, square shape
• Tight, even crumb
• Soft golden crust (not crusty)
• Slices cleanly into ½-inch slices
• Tender mouthfeel

Slicing

Use a long, sharp serrated knife. Slice when fully cool. A bread knife with a guide produces consistent thin slices.

Storage

Wrapped in plastic at room temperature: 3–4 days.

Sliced and frozen: 3 months. Toast from frozen.

Variations

• Whole wheat — substitute 150g whole wheat flour, increase milk by 20g
• Oatmeal — add 75g rolled oats; soak in 75g hot water 1 hour before mixing
• Cheddar jalapeño — add 100g grated cheese and 1 chopped jalapeño at the end of mixing
• Cinnamon swirl — laminate cinnamon-sugar into the dough before final shape

Common mistakes

• Dense, dry — over-baked. Pull at internal temp 200°F.
• Pale crust — under-baked or oven too cool.
• Lopsided — uneven shaping. Roll tightly and evenly.
• Sunken top — over-proofed. The dough collapsed in the oven.
• Tunneling — uneven mixing. Mix until uniform.

Why this matters

A reliable sandwich loaf is the most useful bread you can make. Kids' lunches, weekday breakfasts, leftover-sandwich nights — this is the bread that actually gets eaten.

It's also the bread non-baker friends and family will love most. Rustic country loaves are intimidating; a soft pan loaf is just bread.
