Ingredients for 8 hour sourdough sandwich bread
Pantry staples plus a lively sourdough starter transform into sandwich bread with restaurant-quality texture.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| All-Purpose Flour 🌾 | 4 cups | King Arthur or similar high-protein |
| Bread Flour 🌾 | 1 cup | For enhanced gluten development |
| Granulated Sugar 🍚 | ½ tsp | Feeds yeast for initial fermentation |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Instant Yeast 🍞 | ¼ tsp | For reliable fermentation |
| Water 💧 | 2 ½ cups | Room temperature (70-75°F) |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for richness |
| Honey 🍯 | 1 tsp | Optional for crust color |
Your sourdough starter is the foundation—it should be bubbly and active with a 100% hydration ratio. King Arthur flour is my go-to for the base, but any high-protein all-purpose works. For the bread flour, Bob's Red Mill is reliable and widely available. The yeast and sugar combo kickstarts fermentation while the salt balances flavor. If your kitchen runs cool, add an extra 0.25 tsp yeast—sourdough fermentation is slower than commercial yeast. For the water, room temperature is critical; too cold slows yeast activity, too warm kills it.
No sourdough starter? Instant yeast alone works in a pinch, but the flavor won't be as complex. Swap honey for maple syrup if avoiding it. For a lower-protein flour like White Lily, increase hydration slightly by adding 1 tbsp water. The olive oil adds tenderness—don't skip it. If you're making sandwich rolls instead of a loaf, divide the dough into 8 equal pieces before shaping. For a darker crust, brush with extra honey after baking. And if your kitchen's humid? Reduce flour by 0.25 cup to prevent stickiness.
Store your starter in the fridge when not in use—it'll last weeks. The dough can be shaped and refrigerated overnight for better flavor development. For baking, preheat your oven to 375°F with a Dutch oven inside for 20 minutes. Once baked, let the bread cool on a wire rack for at least 1 hour—this prevents sogginess. Wrapped in a bread bag, it stays fresh for 4-5 days. Freeze slices for up to 3 months by wrapping individually in plastic.

Step-by-step instructions for artisan sourdough sandwich bread
Here's how to craft a loaf with a crisp, golden crust and an open crumb perfect for sandwiches.
Mix the Dough with Precision
In a large mixing bowl, combine the 0.5 cup active sourdough starter, 2.5 cups water, 0.5 tsp granulated sugar, and 0.25 tsp instant yeast. Let this sit for 10 minutes while you measure the flours. The starter should show visible bubbles—this confirms it's ready for action.
Add the 4 cups all-purpose flour and 1 cup bread flour to the bowl. Stir gently with a wooden spoon until a shaggy dough forms. Then, add the 1.5 tsp kosher salt and 1 tbsp olive oil. Mix until the dough comes together, scraping down the sides as needed. The dough will be sticky but should pull away from the bowl sides when you press it.
Develop Gluten Through Kneading
Turn the dough onto a lightly floured surface and knead for 8-10 minutes by hand. Focus on pressing, folding, and stretching the dough to build gluten. You'll know it's ready when the dough becomes smooth, elastic, and springs back slowly when poked. If it feels too sticky, wet your hands slightly to prevent tearing.
For a quicker method, use a stand mixer with a dough hook attachment, kneading on medium speed for 5-6 minutes until the dough passes the windowpane test. This means stretching a small piece of dough thin enough to see light through it without tearing.
Bulk Ferment for Optimal Flavor
Place the dough in a lightly oiled bowl, cover it with a damp kitchen towel, and let it rest at room temperature (70-75°F) for 3-4 hours. During this time, the dough will rise by about 50% and develop complex flavors. Every 30 minutes, perform a "poke test"—press your finger gently into the dough. If it springs back slowly, fermentation is on track.
If your kitchen is cooler, extend the bulk ferment to 5 hours for enhanced flavor development. The dough should look puffy, with large bubbles forming on the surface. This is when the magic happens—the wild yeast in your starter and the added instant yeast work together to create that signature sourdough tang.
Shape and Proof for Structure
After bulk fermentation, gently deflate the dough and divide it into 4 equal portions (about 12 ounces each). Shape each portion into a boule by cupping your hands and pulling the dough toward you while rotating it. This creates surface tension for an open crumb. Place the shaped dough into a 9x5-inch loaf pan that's been lightly greased with olive oil.
Cover the loaf pan with a damp towel and let it proof at room temperature for 1-2 hours, or until the dough has risen 1-2 inches above the pan. The dough should look domed and feel slightly springy when pressed gently. This final proofing step ensures a light, airy texture perfect for sandwiches.
Bake for a Crisp Crust and Soft Interior
Preheat your oven to 375°F with a Dutch oven inside for 30 minutes. This step is critical for steam development, which creates that signature crust. Carefully transfer the loaf pan into the hot Dutch oven, cover it, and bake for 30 minutes. Remove the lid and bake for another 15-20 minutes until the crust is deep golden brown and the internal temperature reaches 190-200°F.
Let the bread cool in the pan for 10 minutes, then transfer it to a wire rack. The crust should be crisp enough to hold up to sandwich fillings, while the interior remains soft and pillowy. Brush the warm bread with 1 tsp honey for a subtle sweetness and extra shine. Slice when completely cooled for clean cuts and maximum sandwich potential.
Pro Tips For Making 8 Hour Sourdough Sandwich Bread
- Weigh Your Flours: Skip the cups—this recipe demands precision. Bread flour and all-purpose flour behave differently by volume, and even a slight mismeasure can throw off your dough’s structure. I learned this the hard way when my sandwich loaves turned out either too dense or too crumbly. Use a kitchen scale for both flours, and don’t round up.
- Autolyse First: Mix your water and flours before adding starter, salt, or sugar—let it sit for 30-60 minutes. This step hydrates the flour fully, making the final knead (or stretch-and-folds) easier and giving you a more extensible dough. I was skeptical until I tried it; my dough now feels smoother and handles better during shaping.
- Don’t Overproof: Your dough is ready when it springs back slowly when poked—about 1-2 hours at room temp. Overproofing (waiting for it to collapse) kills sandwich bread’s airy texture. I used to let mine go until it looked "done," but now I check every 30 minutes after the initial proof. Trust your fingers, not your eyes.
- Steam the Pan: Add a metal tray to the oven floor before preheating, then pour boiling water onto it when loading your dough. This creates steam for the first 15 minutes, helping your crust develop properly without burning. I skipped this once and ended up with a dense, pale loaf—worth the extra 30 seconds of prep.
Dietary considerations for 8 hour sourdough sandwich bread
Gluten-Free Adaptations
For a gluten-free version, replace the all-purpose and bread flour with a 1:1 gluten-free flour blend like King Arthur Measure for Measure. Add 1 tsp xanthan gum to help bind the dough, as gluten-free flours lack natural elasticity.
Keep hydration slightly lower by reducing water to 2.25 cups—gluten-free doughs absorb moisture differently. Expect a denser crumb, but the flavor will still shine with your active sourdough starter. 🌱
Lower-Carb Options
Reduce carbs by swapping 1 cup all-purpose flour for 1 cup almond flour or 1 cup oat flour. Add 1 extra egg to compensate for lost structure. The texture will be slightly denser, but the result is a heartier, nuttier sandwich bread.
For extra flavor, boost the honey to 1.5 tsp and add ½ tsp cinnamon—great for breakfast sandwiches! ⚡
Dairy-Free Considerations
This recipe is naturally dairy-free, but if you're using a gluten-free blend with added milk solids, opt for a certified dairy-free blend like Cup4Cup. The olive oil already provides richness, so no substitutions are needed.
For extra moisture, brush the baked loaf with 1 tbsp melted coconut oil instead of honey. 🥥
Allergen-Friendly Swaps
For nut allergies, stick to the original recipe—it’s free of nuts and dairy. If you must avoid honey, use 1 tsp maple syrup or omit entirely. For egg-free binding, add 1 tbsp ground flaxseed mixed with 3 tbsp water to replace the egg in gluten-free adaptations.
Always check your sourdough starter for cross-contamination if allergies are severe. 💪
Vegan-Friendly Adjustments
Make this fully vegan by omitting honey and using 1 tbsp maple syrup instead. For gluten-free vegan dough, use a blend like Bob’s Red Mill 1-to-1 Gluten-Free Flour and add 1 tbsp psyllium husk powder to improve texture.
Let the dough rest 10 minutes longer during bulk fermentation—vegan doughs often need extra time to develop gluten substitutes. 🌿

Frequently asked questions
Can I make this sandwich bread without a Dutch oven?
Yes! If you don’t have a Dutch oven, use a heavy oven-safe pot with a lid or even a metal bowl. Place the loaf pan inside and cover tightly with foil. For extra steam, add a tray of boiling water to the oven. The crust won’t be as crisp, but the interior will still be soft and flavorful.
Why is my dough too sticky after mixing?
Sticky dough is normal with this recipe’s 60% hydration (water-to-flour ratio). To handle it, wet your hands slightly when shaping and use a dough scraper for cleanup. If it’s too sticky, add 1 tbsp flour at a time until it’s manageable—but avoid over-drying it. The stickiness actually helps develop gluten during fermentation.
How do I know when the dough is fully proofed?
Press your finger gently into the dough. If it springs back slowly (like jelly) and leaves a faint indentation, it’s ready. For a loaf pan, the dough should rise 1-2 inches above the rim. If it springs back quickly, it needs more time. Cold weather? Extend proofing by 30-60 minutes—the dough rises slower when temperatures drop.
Can I make this recipe with just yeast (no sourdough starter)?
Yes, but the flavor will be less complex. Replace the 0.5 cup starter with 0.25 tsp extra instant yeast and 0.25 cup warm water. The dough will rise faster but lack the tangy depth of sourdough. For a compromise, use 0.25 cup starter + 0.125 tsp yeast to balance speed and flavor.
How should I store leftover sandwich bread?
Wrap cooled slices in plastic wrap or store in an airtight container. It stays fresh for 4-5 days at room temperature. For longer storage, freeze slices individually for up to 3 months. To revive, toast frozen slices for 2-3 minutes** longer than fresh. The crust stays crisp, and the interior remains soft when toasted.
