Side Dishes
This all-purpose flour sourdough sandwich bread recipe delivers restaurant-quality texture with a soft, open crumb and tangy depth—perfect for toast, sandwiches, or charcuterie boards.
The beauty of this recipe lies in its balance: traditional sourdough fermentation creates that signature flavor and structure, but all-purpose flour ensures a reliable, sandwich-friendly loaf every time. I’ve perfected the technique over years of baking, eliminating guesswork while preserving the soul of sourdough.
What sets this recipe apart is the two-stage fermentation—a slow starter build (24–48 hours) followed by a controlled bulk fermentation (4–6 hours). This ensures a light, airy crumb without sacrificing the sourdough tang.
The dough is shaped into a classic sandwich loaf, scored for an even rise, and baked until the crust achieves that golden, crisp contrast to the soft interior. No special equipment is needed beyond a mixing bowl and Dutch oven (or baking sheet).
The result is a loaf with even slices, a tender crumb, and just enough acidity to elevate buttered toast or hold up to deli meats.
The crust stays soft for days, making it ideal for sandwiches, while the interior remains springy and slightly chewy—the hallmark of great sandwich bread. This recipe is your gateway to foolproof sourdough without the intimidation.
For customization, add whole grains, seeds, or herbs to the dough, but the base recipe delivers consistent, professional results every time. Let’s bake this loaf that’s equal parts art and science.
Ingredients for all purpose flour sourdough sandwich bread
Four cups of all-purpose flour meet active starter and precise fermentation for restaurant-quality sandwich bread.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 cups | Bread flour alternative for lighter crumb |
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| Granulated Sugar 🍚 | ¼ cup | Feeds starter for fermentation |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for optimal texture |
| Large Eggs 🥚 | 1 whole | Room temperature for even mixing |
| Instant Yeast 🍞 | ¼ tsp | For reliable fermentation boost |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain for even distribution |
| Water 💧 | 1 ½ cups | Room temperature, filtered preferred |
| Olive Oil 🫒 | 1 tbsp | For dough handling and scoring |
| Cornmeal 🌽 | ¼ cup | For dusting parchment paper |
| Ice Water ❄️ | ¼ cup | For final dough shaping |
The all-purpose flour is the secret here—it delivers the reliable, sandwich-friendly crumb the intro promises while still capturing sourdough's tang. For best results, use King Arthur or Gold Medal brands, which have consistent protein levels (10-12%) for predictable gluten development. The sourdough starter must be 100% hydration and actively bubbling; discard any portion that's sluggish or smells off. King Arthur's sourdough starter is a reliable commercial option if you're new to fermentation. For the butter, Plugrá or Land O'Lakes unsalted work best—they stay firm enough to cube properly without melting during mixing.
No instant yeast? Active dry yeast at double the time works, but timing becomes critical. The granulated sugar can be swapped for honey or maple syrup (reduce water by 1 tbsp), though this may slightly alter fermentation speed. For a whole-grain variation, replace 1 cup of all-purpose flour with white whole wheat flour—it adds subtle nuttiness without overpowering the delicate crumb structure. The olive oil is non-negotiable for scoring; extra-virgin varieties like Colavita add subtle fruitiness that enhances the crust's complexity. If you're baking in a high-altitude area, increase the flour to 4.25 cups and reduce water by 1 tbsp to compensate for lower atmospheric pressure.
The dough's two-stage fermentation requires patience—never rush the bulk rise beyond 6 hours or the crumb will suffer. For storage, wrap the cooled loaf in a clean kitchen towel and place in a paper bag at room temperature for up to 3 days. The crust stays crisp for 2 days, while the interior remains fresh for 5 days when refrigerated in an airtight container. For freezing, slice the loaf before wrapping in plastic—toast directly from frozen for best results. The cornmeal dusting prevents sticking during shaping, but semolina works equally well if you prefer its nutty flavor profile.
Why You'll Love This Recipe
- Pantry-Friendly Magic: This bread uses what you already have—no specialty flour, no waiting for fermentation to magically happen. Just toss in your starter, a splash of sugar for a subtle caramel note, and let the butter and eggs work their richness into the dough. Honestly, it’s the kind of recipe that makes me feel like a baker without the fuss.
- Buttery Tang Alert: That little egg wash? Chef’s kiss. The crust gets golden and crisp, while the inside stays soft with just enough tang from the starter to make plain toast taste like a treat. Between us, I’ve cut this bread into squares just to snack on it straight from the pan.
- Weeknight Hero: Make a batch on Sunday, and you’ve got lunch covered for days—no sad, dried-out sandwiches here. The butter keeps it moist, and the all-purpose flour means it slices neatly for grilled cheese, PB&J, or even a quick charcuterie board. (Yes, even on a Tuesday night.)
- Budget Stretch: A single batch costs pennies but feels like a splurge. The sugar adds a touch of sweetness without breaking the bank, and the eggs and butter make it feel indulgent. I’ve even frozen leftovers—just toast straight from the freezer, and no one’s the wiser. My wallet thanks me every time.
Step-by-step instructions for all-purpose flour sourdough sandwich bread
Master this method and you'll achieve a perfectly balanced loaf with a crisp crust and open crumb structure.
Mix the Dough for Optimal Fermentation
In a large mixing bowl, combine the 4 cups all-purpose flour, 0.5 cup active sourdough starter, 0.25 cup granulated sugar, 1.5 tsp diamond crystal kosher salt, and 0.25 tsp instant yeast. Mix these dry ingredients using a wooden spoon or your hands until evenly distributed—small lumps are fine at this stage. This ensures the yeast and salt disperse completely throughout the flour.
Create a well in the center and add the 1 whole large egg and 0.5 cup cold unsalted butter, cut into small cubes. Gently work these wet ingredients into the flour mixture using a dough whisk or your fingers. The butter should remain in small, pea-sized pieces at this point—this creates pockets of flavor and texture in the final loaf. Once combined, gradually add the 1.5 cups room-temperature water while mixing continuously. The dough will begin to come together as the water hydrates the flour.
Knead and Develop Gluten for Structure
Turn the dough onto a lightly floured surface and knead vigorously for 8-10 minutes by hand, or use a stand mixer with a dough hook attachment on medium speed for 5-6 minutes. You're looking to develop gluten—this gives the bread its structure and chew. The dough should become smooth, elastic, and slightly tacky, pulling away cleanly from the surface when stretched gently. If it feels too sticky, add 1 tablespoon flour at a time until it becomes manageable.
Real talk: Don't rush this step. Proper gluten development prevents a dense, gummy loaf. Test for readiness by performing the "windowpane test"—stretch a small piece of dough thinly. If it holds without tearing and is translucent, it's ready. Shape the dough into a round ball, place it back in the mixing bowl, cover with a damp towel, and let it rest at room temperature for 30 minutes. This initial rest allows the gluten to relax, making it easier to shape later.
First Bulk Fermentation for Flavor Development
After the rest, shape the dough into a loose round and transfer it to a lightly greased bowl. Cover with a damp towel or plastic wrap and let it ferment at 75°F for 3-4 hours, or until it has nearly doubled in size. This bulk fermentation is where the magic happens—the yeast feeds on the sugar and starter, creating gases that expand the dough and develop those signature sourdough flavors. You'll see bubbles forming on the surface and along the sides of the bowl.
I know it seems like a long wait, but this step is non-negotiable. If your kitchen is cooler, extend the fermentation time by 1-2 hours—the dough should still show significant rise and have a slightly jiggly consistency when gently shaken. Patience here ensures a well-developed crumb structure and maximum flavor extraction from the starter and butter.
Shape and Final Proof for Crust Development
Turn the dough onto a lightly floured surface and gently deflate it by pressing down with your fist. Shape it into a tight round loaf by pulling the edges toward the center and tucking them under. This creates surface tension that helps maintain the loaf's shape during baking. Place the shaped dough seam-side up in a greased 9x5-inch loaf pan, cover with a damp towel, and let it proof at 75°F for 1-2 hours, or until it rises 1-2 inches above the rim of the pan.
Here's where precision matters: The dough should spring back slowly when poked with a finger, not quickly. If it's ready too soon, place it in the refrigerator for 30 minutes to slow fermentation—this helps prevent overproofing and a collapsed loaf. While it proofs, preheat your oven to 375°F and place a baking sheet on the lower rack to catch any potential drips.
Bake for Crusty Exterior and Open Crumb
Remove the proofed loaf from the pan and score the top with a sharp razor or bread knife, making a ½-inch deep crosshatch pattern. This allows steam to escape during baking, preventing the loaf from bursting open in unpredictable ways. Brush the scored surface with 1 tablespoon olive oil—this creates a crisp, golden crust and adds subtle flavor. Dust a baking sheet with 0.25 cup cornmeal and place the loaf on it.
Bake in the preheated oven for 35-40 minutes, until the crust is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 190-200°F at the center. If the top browns too quickly, tent the loaf loosely with aluminum foil to prevent over-browning while ensuring even cooking. The bread is done when it pulls away cleanly from the sides of the pan and has a crisp crust with an open, airy crumb.
Cool and Slice for Maximum Freshness
Remove the bread from the oven and transfer it to a wire cooling rack. Let it cool completely for at least 1 hour before slicing—this allows the crumb to set properly and prevents a gummy texture. The bread will continue to firm up as it cools, developing that perfect balance of crisp crust and tender interior. For extra tangy depth, you can brush the cooled loaf with a simple water-glaze (mix 1 tablespoon water with 1 teaspoon sugar) before serving.
Slice the bread with a serrated knife for clean cuts that showcase the open crumb structure. Each slice should reveal an even distribution of air pockets and butter flecks, with a crisp exterior that gives way to a soft, chewy interior. Store any leftovers in an airtight container at room temperature for 2-3 days or freeze for up to 3 months—the flavor actually improves with age as the starches retrograde.
Pro Tips For Making All Purpose Flour Sourdough Sandwich Bread
- CHILL THE DOUGH: I learned this the hard way—after autolyse, let the dough rest in the fridge overnight. All-purpose flour lacks gluten strength, so the cold slows fermentation and helps those proteins relax. Skip this, and your sandwich bread might turn out dense or tear apart like wet paper.
- WEIGH YOUR STARTER: Active sourdough starter is finicky. Weigh it by grams (100g) instead of eyeballing it—fluctuating hydration messes with your dough’s structure. I used to dump in "a handful," and my bread never rose predictably. Precision here makes a real difference.
- STEAM THE FIRST 10 MINUTES: Preheat your Dutch oven with a metal rack inside, then add a metal tray of boiling water when loading the dough. The steam creates a crackly crust without burning the top—critical for sandwich bread where you want that golden snap but not a charred lid. (Yes, even if you’re impatient like me.)
- SOFTEN THE BUTTER: Cold butter creates pockets in the dough, but it won’t emulsify properly. Warm the unsalted butter to room temp (about 65°F) before mixing it into the final dough. This ensures even distribution and a tender crumb—no more greasy patches or dry spots in your sandwich slices.
Troubleshooting this recipe
Dense Dough Issues
If your dough feels too dense or gummy after kneading, you likely didn’t develop enough gluten. Try kneading by hand for 10-12 minutes or use a stand mixer with a dough hook for 6-8 minutes on medium speed.
For extra insurance, let the dough rest 30 minutes after kneading before shaping—this relaxes the gluten strands. If it’s still too sticky, add 1 tablespoon flour at a time until it becomes manageable but not dry. 💪
Underproofed Loaf
An underproofed loaf will be heavy with a tight crumb. Check for readiness by gently pressing your finger into the dough—it should spring back slowly (not quickly).
If your kitchen is below 70°F, extend bulk fermentation by 1-2 hours or use a proofing box (or warm oven with light on) to maintain 75°F. For sandwich bread, aim for 4-6 hours total bulk fermentation to ensure a light, airy texture.
Collapsed Crust
A collapsed crust usually means overproofing or insufficient scoring. Before baking, score the loaf with a sharp razor in a ½-inch deep crosshatch pattern to control steam release. If the dough overproofs (springs back too quickly when poked), refrigerate it for 30 minutes to slow fermentation.
For extra support, shape the dough into a tight round before placing it in the pan to create surface tension.
Pale or Soft Crust
A pale crust often results from insufficient baking time or steam. Preheat your oven to 375°F and bake for 35-40 minutes, until the crust is deep golden brown. Brush the scored surface with 1 tablespoon olive oil before baking to enhance browning.
For extra steam, place a baking sheet on the lower oven rack during the first 10 minutes of baking. If your oven runs hot, tent the loaf loosely with aluminum foil after 20 minutes to prevent over-browning.
Uneven Rise
Uneven rise typically occurs from improper shaping or inconsistent fermentation. When shaping, pull the edges toward the center and tuck them under to create surface tension. If one side rises faster, rotate the pan halfway through proofing to ensure even heat distribution.
For a more controlled rise, proof the dough in the refrigerator for 12-16 hours—this slow fermentation yields a more uniform crumb and crust.
Gummy Interior
A gummy interior usually means the bread didn’t cool properly or was sliced too soon. Let the loaf cool completely (1+ hour) before slicing to allow starches to set. If the crumb feels sticky, the dough may have been underproofed or overhydrated.
To fix this, reduce water by 1 tablespoon in future batches and ensure bulk fermentation reaches near-doubled size. For extra tenderness, brush the cooled loaf with a water-glaze (1 tbsp water + 1 tsp sugar) before serving. ✨

Frequently asked questions
Can I substitute bread flour for all-purpose flour in this recipe?
While you can use bread flour, it will make the crumb slightly denser and chewier. This recipe is specifically designed for all-purpose flour to achieve that perfect sandwich bread texture—soft yet sturdy enough to hold fillings. If you do substitute, reduce the total flour by 1 tablespoon to account for bread flour's higher protein content.
How do I know when my sourdough starter is ready for this recipe?
Your starter should be bubbly, slightly domed, and smell tangy (like yogurt or vinegar). It should also float in water to confirm it's active. For best results, use starter that's between 24-48 hours old and has doubled in size within 4-6 hours at room temperature. If it's sluggish, feed it with equal parts flour and water and wait another 4-6 hours before using.
Why does this recipe use both yeast and sourdough starter?
The combination creates a balanced fermentation—yeast provides reliable, predictable rise while the sourdough starter contributes depth of flavor and natural acidity. The instant yeast kicks in quickly for structure, while the starter works slowly to develop complexity. This hybrid approach is perfect for sandwich bread where you want both reliable results and that authentic sourdough tang.
Can I make this bread without a Dutch oven or special equipment?
This recipe uses a standard loaf pan and baking sheet. For best results, place a baking sheet on the lower oven rack during the first 10 minutes of baking to create steam. Score the loaf with a sharp knife before baking to control expansion. The crust will be slightly less dramatic than with a Dutch oven, but the interior texture will remain excellent for sandwiches.
How can I add flavor variations to this sandwich bread?
For subtle flavor enhancements, try adding 1 tablespoon of seeds (sesame, poppy, or flax) or 1 teaspoon of dried herbs (rosemary or thyme) to the dough. For a sweeter version, replace 1 tablespoon of water with honey. For a savory twist, add 1 teaspoon of garlic powder or ½ teaspoon of onion powder to the dough. Always adjust water by 1 tablespoon if adding dry ingredients to maintain proper hydration.
