Side Dishes
This 8-hour sourdough sandwich bread recipe delivers the perfect balance of artisan-style crust and pillowy softness—just like your favorite bakery loaf, but made at home. The key lies in the 8-hour fermentation process, which develops deep flavor and a light, airy crumb.
I’ve refined this method over years of baking, ensuring every slice is tender enough for sandwiches while maintaining that coveted crispy crust.
The process begins with an autolyse to hydrate the flour fully, followed by a bulk fermentation that builds structure and flavor. After shaping and a cold proof overnight, the bread bakes to a golden, crackling crust with an open crumb that’s impossible to resist.
This isn’t just bread—it’s a foolproof technique that transforms simple ingredients into something extraordinary.
What you’ll end up with is a versatile loaf perfect for sandwiches, toast, or charcuterie boards. The crust stays crisp for days, while the crumb remains soft and flavorful. Whether you’re a beginner or an experienced baker, this recipe delivers restaurant-quality results with minimal effort.

Ingredients for 8 hour sourdough sandwich bread
Nine essential ingredients transform your kitchen into a bakery with that perfect artisan crust.
| Ingredient | Amount | Notes |
|---|---|---|
| Unbleached Bread Flour 🌾 | 4 cups | High-protein for structure and chew |
| Active Sourdough Starter 🍞 | 1 cup | 100% hydration, bubbly and active |
| Water 💧 | 2 ½ cups | Filtered or dechlorinated preferred |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Honey 🍯 | 1 tbsp | Wildflower or clover variety |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for flavor and shine |
| Instant Yeast 🍞 | ¼ tsp | Optional for extra lift |
| Cornmeal 🌽 | ¼ cup | For dusting baking sheet |
| Ice Water ❄️ | ½ cup | For final dough shaping |
The flour is non-negotiable here—King Arthur or Caputo bread flour give the best results, but Bob’s Red Mill unbleached works too if you’re in a pinch. Your sourdough starter should be peaked and bubbly—if it’s sluggish, feed it 12 hours before using. Honey adds subtle sweetness and helps with browning; local raw honey has more flavor than store-bought. The olive oil isn’t just for flavor—it improves gluten development. I keep mine in a dark glass bottle in the pantry to preserve freshness. For the yeast, Saf-Instant is my go-to because it’s foolproof.
No sourdough starter? 1 tsp active dry yeast plus 1 tbsp sugar can stand in, but the flavor won’t be the same. Short on honey? Maple syrup works 1:1, but it’s stronger. Using store-bought bread flour? Add 1 tbsp vital wheat gluten per cup to boost protein. The cornmeal is crucial—it prevents sticking and adds that golden crust. For the ice water, crushed ice works too if you’re in a hurry. And if you’re baking in a dry climate, add 1 tsp olive oil to the dough for extra tenderness.
Store the flour in an airtight container in the freezer for long-term freshness, but keep it at room temperature for daily use. Your starter should live in a glass jar on the counter, fed daily. The finished dough can be shaped and cold-proofed in the fridge for up to 24 hours—this actually improves flavor. Baked loaves keep well wrapped at room temperature for 3 days, or freeze for 3 months in slices. Toasting revives stale bread instantly.
Why You'll Love This Recipe
- No-Knead, No-Fuss: I’ll admit, I was skeptical about an 8-hour process—but the dough comes together in five minutes of actual work. Just toss the flour, starter, water, and honey, let it rest, and walk away. That’s it.
- Honey-Sweet Tang: The honey isn’t just for flavor—it keeps the crust golden and the crumb tender, while the sourdough tang gives it that just-baked depth. Toast it, and you’ve got a sandwich bread that tastes like a bakery’s secret.
- Weeknight Workhorse: This bread is my go-to for lunchboxes, charcuterie boards, or a quick PB&J when I’m running late. It holds up for days in the fridge (yes, even after the third slice), and freezes beautifully for when I forget to bake.
- Budget Bakery Trick: Unbleached flour and a little honey stretch further than store-bought loaves, and you’re using your starter—no waste. I make two loaves at once, and they disappear faster than I can say “leftovers for dinner.”
Step-by-step instructions for artisan-style sourdough sandwich bread
Here's how to craft a sandwich loaf with a crisp crust and tender crumb—no shortcuts, just perfect technique.
Autolyse the Dough for Maximum Development
In a large mixing bowl, combine the 4 cups unbleached bread flour and 2.5 cups water using a dough whisk or your hands. Mix until no dry flour remains—this creates a shaggy dough with no gluten development yet. Cover the bowl with a damp towel and let it rest at room temperature for 30 minutes. This autolyse step hydrates the flour fully and relaxes the gluten, making the final kneading easier and producing a more extensible dough.
During this time, the flour absorbs moisture evenly, and the starches begin to swell. You'll notice the dough becomes smoother and more cohesive. This is your foundation for that signature open crumb structure we're after in sandwich bread. Don't skip this step—it's what separates good sourdough from exceptional sourdough.
Incorporate Starter, Salt, and Ferment for 4 Hours
After the autolyse, add the 1 cup active sourdough starter, 1.5 tsp kosher salt, 1 tbsp honey, and 1 tbsp olive oil to the dough. Using a dough scraper, fold these ingredients into the center of the dough, then perform a series of stretch-and-folds: wet your hands, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this process 4-5 times, turning the dough as you go. This develops gluten while incorporating all ingredients.
Cover the bowl again and let the dough ferment at room temperature for 4 hours. You're looking for about 50-75% bulk fermentation—the dough should nearly double in size and develop small bubbles on the surface. The honey adds subtle sweetness while feeding the yeast, and the olive oil contributes richness and helps with oven spring. Check the dough after 2 hours—if it's rising slowly, move it to a slightly warmer spot (around 75°F).
Perform Two Sets of Laminations for Open Crumb
After the initial fermentation, perform two sets of laminations with 30 minutes rest between each. For each set, turn the dough onto a lightly floured surface and gently deflate it with your fingers. Then fold it into thirds like a letter: fold the right side over the center, then the left side over the new center. Rotate the dough 90 degrees and repeat the folding process. This creates layers that will give your bread that beautiful open crumb structure perfect for sandwiches.
After each set of folds, return the dough to the bowl, cover it, and let it rest. The dough should feel slightly resistant but still soft to the touch. These laminations aren't about developing gluten—they're about creating structure that will hold up to slicing and toasting. The rest periods allow the gluten to relax between folds, preventing overdevelopment.
Pre-Shape, Bench Rest, and Final Shape
After the second lamination, turn the dough onto a lightly floured surface and gently shape it into a loose round by pulling the edges toward the center. Cover the dough with a damp towel and let it rest for 20-30 minutes—this bench rest relaxes the gluten after all the folding. Then shape the dough into a tight oval by pulling the edges toward the center and sealing the seam. The final shape should be smooth with no cracks or tears.
Place the shaped dough seam-side down on a piece of parchment paper dusted with ¼ cup cornmeal. The cornmeal creates a barrier that prevents sticking and adds a subtle flavor. Cover the dough and let it proof at room temperature for 1-1.5 hours, or until it has risen by about 50%. You're looking for a gentle dome shape with visible bubbles on the surface. The dough should spring back slowly when poked with a finger—this indicates proper fermentation without overproofing.
Score, Bake, and Develop the Crust
Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. While the oven heats, score the dough with a razor blade or sharp knife: make a ½-inch deep cut down the center of the oval, then make two parallel cuts on each side about ¼ inch apart, creating a crosshatch pattern. This scoring prevents the dough from bursting open unpredictably and creates those beautiful crust patterns.
Carefully transfer the scored dough (with parchment) into the hot Dutch oven. Bake covered for 20 minutes, then remove the lid and bake uncovered for another 20-25 minutes until the crust is deep golden brown and sounds hollow when tapped on the bottom. The internal temperature should reach 205-210°F. Immediately after baking, remove the loaf from the Dutch oven and let it cool on a wire rack for at least 2 hours before slicing—this allows the crumb to set properly and prevents a gummy texture.
Pro Tips For Making 8 Hour Sourdough Sandwich Bread
- STRETCH THE DOUGH LONG ENOUGH: I learned this the hard way—skipping the full 30-minute stretch-and-fold in the 8-hour schedule leaves gluten underdeveloped, and your sandwich bread turns out gummy no matter how long it bakes. Those extra minutes of gentle pulling and folding make the difference between a floppy loaf and one with proper structure.
- WEIGH YOUR FLOUR PRECISELY: Bread flour clumps like a nightmare when scooped, and even a 5-gram miscalculation throws off hydration. Use a kitchen scale and tap the bowl lightly to settle flour before measuring—this 8-hour recipe is unforgiving if your ratios are off.
- SALT THE WATER, NOT THE DOUGH: I used to toss all the kosher salt into the flour mix, and my bread always tasted unevenly salty. Dissolve the salt in the water first—it distributes perfectly and prevents pockets of saltiness while keeping the flavor balanced.
- BAKE WITH STEAM FIRST: The first 10 minutes in the oven should be with a tray of boiling water on the bottom rack—this creates steam that helps the crust form evenly and prevents a dense, heavy crumb. Skip this, and you’ll end up with a loaf that looks more like a brick than artisanal bread.
Storing and reheating your 8 hour sourdough sandwich bread
Room-Temp Storage
Keep your freshly baked loaf in a brown paper bag or cotton towel at room temperature for up to 3 days. The paper bag mimics bakery conditions by trapping steam, which helps maintain that perfect crust-to-crumb ratio.
I always store my loaves in a cool, dark pantry—never the fridge, as this can dry out the bread faster. For extra protection, wrap the loaf in parchment paper before placing it in the bag. 🌾
Fridge Preservation
If you need to store for 4-5 days, place the loaf in an airtight container with a damp paper towel to prevent drying. The fridge slows staling but can make bread taste slightly off—so I only use this method when necessary.
For sandwich bread, I recommend slicing before refrigerating to maintain softness. Remove slices as needed and toast immediately to revive texture. 🥖
Freezer Perfection
For long-term storage, freeze the loaf in slices wrapped tightly in plastic wrap followed by aluminum foil. I use quart-sized freezer bags for individual portions—this prevents freezer burn and makes reheating a breeze.
Label with the date and store for up to 3 months. The crust stays crisp, and the crumb remains soft when properly reheated. 🧊
Reviving Stale Bread
Stale bread is a baker’s worst nightmare, but I’ve got you covered. For room-temperature loaves, wrap in a damp towel and place in a 350°F oven for 5-10 minutes—this steams the bread and restores moisture.
For fridge-stored slices, toast in a toaster oven at 375°F for 2-3 minutes with a spritz of water for extra crispiness. 🔥
Microwave Rescue
When you’re in a hurry, the microwave works surprisingly well. Place a single slice on a plate, cover with a damp paper towel, and heat at 50% power for 15-20 seconds.
The steam softens the crumb while keeping the crust intact. For extra flavor, brush with melted butter after reheating. This method is my go-to for quick sandwich prep. ⏱️
Cold Proofing Shortcut
Need to speed up the process? Shape your dough as directed, then refrigerate for 8-12 hours instead of proofing at room temperature. This cold proofing not only saves time but also enhances flavor development.
When ready to bake, let the dough sit at room temperature for 1 hour before scoring and baking. Your loaf will have deeper flavor and better structure. ❄️

Frequently asked questions
Why does this recipe use an 8-hour fermentation instead of overnight?
This 8-hour fermentation creates the perfect balance between flavor development and texture for sandwich bread. Unlike overnight cold fermentation (which builds more tang), this method produces a lighter, more open crumb while still developing rich sourdough character. The 4-hour bulk fermentation at room temperature activates the starter fully, while the 4-hour cold proof enhances flavor without overproofing.
Can I use whole wheat flour instead of bread flour?
You can substitute up to 25% whole wheat flour for a nuttier flavor, but expect a denser crumb. For best results, replace 1 cup bread flour with whole wheat and add 1 tbsp vital wheat gluten to maintain structure. Whole wheat absorbs more water, so you may need to add 1-2 tbsp extra water to the dough. Fermentation will take slightly longer—watch closely for 50-75% rise.
What if my dough doesn't rise enough during the 4-hour bulk fermentation?
If your dough is sluggish, check these first: your starter should be peaked and bubbly (feed it 12 hours before using if needed), and your kitchen should be 70-75°F. Try moving the dough to a warmer spot (like near the oven with it off) or cover it with a damp towel + plastic wrap to trap heat. If it still doesn't rise, add 0.25 tsp extra instant yeast and let it ferment another 1-2 hours. Overproofing is easier to fix than underproofing!
How do I know when the bread is fully baked?
The bread is done when the internal temperature reaches 205-210°F and the crust is deep golden brown. Tap the bottom—it should sound hollow like a drum. The edges should pull away slightly from the Dutch oven. If the top browns too quickly, tent with foil during the uncovered bake. Never rely on color alone—always check the internal temp with an instant-read thermometer for perfect results.
Can I make this recipe without a Dutch oven?
Yes! If you don’t have a Dutch oven, use a commercial baking stone or cast-iron skillet on the lowest oven rack. For extra steam, place a pan of boiling water on the middle rack while baking. The bread may have a slightly less crisp crust but will still have a great open crumb. Preheat the stone/skillet for 1 hour before baking, and bake covered with foil for the first 20 minutes.
