Side Dishes
This 8-hour sourdough sandwich bread delivers the perfect balance of a crispy crust and tender interior—ideal for sandwiches or toast. The key lies in the slow fermentation process, which develops deep flavor and an open crumb structure without requiring overnight proofing.
I’ve perfected this method to ensure consistent results every time, even for beginners.
The recipe begins with a simple starter, which you’ll feed and use to create a dough that rests for 4 hours before shaping and proofing for 4 more hours.
This extended fermentation transforms basic ingredients into bread with a complex, tangy flavor and a texture that’s both airy and sturdy enough to hold fillings. The secret? A controlled environment and patience—no rushing the process.
By the time it emerges from the oven, you’ll have a loaf with a golden, crackly crust and a soft, open crumb that’s perfect for slicing. The bread stays fresh for days, making it ideal for meal prep or gifting.
Whether you’re making grilled cheese or simply enjoying it with butter, this recipe ensures every bite is satisfying.
For best results, use a Dutch oven to trap steam and create that signature oven spring. The dough is forgiving, so don’t stress over imperfections—this bread is all about the process and the reward of homemade flavor. Let’s get started on crafting your perfect loaf.
Ingredients for 8 hour sourdough sandwich bread
Nine simple ingredients transform into restaurant-quality sandwich bread with perfect crust and crumb.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | Well-fed, bubbly starter |
| All-Purpose Flour 🌾 | 3 ½ cups | Bread flour preferred |
| Unbleached Bread Flour 🌾 | 1 cup | For better texture |
| Warm Water 💧 | 1 ½ cups | 105°F for ideal hydration |
| Kosher Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Honey 🍯 | 1 tbsp | For slight sweetness |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for crust |
| Cornmeal 🌽 | ¼ cup | For dusting Dutch oven |
| Ice Water ❄️ | ¼ cup | For final dough chill |
The sourdough starter is your secret weapon—it should be bubbly and active with a slight tang. If yours isn't ready, feed it overnight. For flour, King Arthur or Bob's Red Mill bread flour gives the best texture, but all-purpose in a pinch works too. The butter matters here—use European-style butter like Plugrá if you can splurge, but regular unsalted works fine. Keep everything cold until you're ready to mix, especially that butter. The cornmeal isn't just for dusting—it adds a subtle crunch to the crust that's perfect for sandwiches.
No bread flour? Swap in all-purpose plus 1 tbsp vital wheat gluten for better structure. Short on honey? Maple syrup at the same amount works too. The Dutch oven is non-negotiable—if you don't have one, use a heavy oven-safe pot with a lid. For shaping, wet your hands slightly to prevent sticking. The dough will feel sticky, but that's normal. If your starter isn't ready, instant yeast at 1/4 tsp can jumpstart fermentation, though it won't taste exactly the same. The ice water at the end helps tighten the gluten for better oven spring.
This dough is best made fresh, but you can shape and refrigerate it overnight for a slower rise. The bread keeps for 4-5 days at room temperature wrapped in a towel, or 1 week in the fridge. For longer storage, freeze slices wrapped in plastic—they'll toast up like fresh. The crust gets crunchier as it cools, so slice when it's still slightly warm. Leftovers? Perfect for croutons or bread pudding—this bread is too good to waste.

Step-by-step instructions for perfect sourdough sandwich bread
Here's how to craft artisanal sandwich bread with a crackly crust and pillowy interior—no fancy equipment needed.
Mix the Dough with Precision
In a large mixing bowl, combine the 0.5 cup active sourdough starter, 3.5 cups all-purpose flour, 1 cup unbleached bread flour, and 1.5 tsp kosher salt. Stir until the flour is fully incorporated and no dry spots remain. This blend of flours gives us that perfect balance of structure and tenderness.
Next, add the 1.5 cups warm water (about 105°F) and 1 tbsp honey, mixing until a shaggy dough forms. The honey not only adds subtle sweetness but also helps activate the starter slightly. Let the dough rest for 5 minutes—this initial hydration is crucial for gluten development.
Knead and Develop Gluten
Using a stand mixer fitted with the dough hook, knead the dough on medium speed for 5-7 minutes until it becomes smooth and elastic. If using your hands, knead for 8-10 minutes until the dough passes the "windowpane test"—stretch a small piece until it's thin enough to see light through without tearing.
This kneading step builds the gluten network that traps gas during fermentation, giving us that signature soft interior. If the dough feels too sticky, add 1 tablespoon of flour at a time until it comes together cleanly. Shape the dough into a loose ball, lightly oil the bowl, and let it rise at room temperature for 1 hour until it doubles in size.
Laminate and Shape for Crust
Turn the dough onto a lightly floured surface and gently deflate it. Using a rolling pin, roll the dough into a 12x8-inch rectangle. Spread the 0.25 cup cold, cubed unsalted butter evenly over the surface, leaving a ½-inch border uncovered. This butter will create pockets of steam during baking, contributing to that irresistible crust.
Fold the dough into thirds like a letter, then rotate the rectangle 90 degrees and fold into thirds again. This "letter fold" technique creates layers that develop during the final proof, giving us that signature sandwich bread texture. Shape into a loaf and place seam-side down in a bowl lined with a damp towel. Cover and let it rise for 1 hour until puffy.
Pre-Shape and Final Proof
Lightly dust a work surface with 0.25 cup cornmeal and transfer the dough. Gently shape it into a 2-inch thick log, tapering the ends slightly. Place the loaf seam-side up in a 9x5-inch loaf pan dusted with cornmeal. Cover loosely and let it proof at room temperature for 45 minutes until it rises 1 inch above the pan.
For the final touch, sprinkle 1 tablespoon ice water over the dough and gently press it down to create a smooth, domed top. This chills the surface slightly, helping develop that crackly crust. Preheat your oven to 425°F with a Dutch oven inside for 30 minutes—this creates the perfect steam environment for baking.
Bake to Golden Perfection
Carefully transfer the loaf pan to the preheated Dutch oven. Bake uncovered for 30 minutes, then remove the lid and bake for another 15-20 minutes until the bread reaches an internal temperature of 190-195°F and the crust is deep golden brown. Tap the bottom—it should sound hollow.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack. The interior should be soft and slightly sticky, while the exterior boasts that satisfying crunch. Slice while still warm for the best texture—each bite will be a perfect balance of crusty exterior and tender crumb.
Pro Tips For Making 8 Hour Sourdough Sandwich Bread
- Weigh Your Flours: Skip the cups—this isn’t a guess-your-way-through recipe. Bread flour and all-purpose behave differently when weighed, and your hydration (that water-to-flour ratio) will be off if you eyeball it. I learned this the hard way when my first loaf turned out dense as a brick. Use a kitchen scale for accuracy, especially since your starter’s weight matters too.
- Autolyse First: Mix your flours and water before adding salt or starter—let it sit for 30-60 minutes. This step hydrates the flour fully, develops gluten passively, and makes mixing later feel like a breeze. I used to skip it, and kneading always felt like wrestling with wet cement.
- Don’t Overproof the Dough: Your dough’s ready when it springs back slowly when poked—like Jell-O, not a trampoline. Overproofing (leaving it too long) collapses the structure, and your sandwich bread will turn out gummy instead of chewy. Set a timer if you’re distracted; I’ve ruined batches by walking away for “just five minutes.”
- Steam the Oven: Toss a metal bowl of boiling water in your oven before baking—this creates steam that mimics a bread proofer’s environment. Without it, your crust will dry out before the crumb sets, leaving you with a sad, crackly exterior. Do this for the first 10 minutes, then pull the bowl. Trust me, your sandwich bread’s crust will thank you.
Creative variations of 8 hour sourdough sandwich bread
Sweet & Savory Twist
Add 1 tbsp cinnamon and ½ tsp cardamom to the dough for a subtle sweetness that pairs perfectly with savory fillings. I like to brush the baked loaf with a mix of 2 tbsp melted butter and 1 tbsp maple syrup while still warm.
This version works amazingly with breakfast sandwiches or even as a dessert bread with jam and cream cheese. 🍯
Herb-Infused Variations
For a fresh twist, stir 1 tbsp finely chopped rosemary or thyme directly into the dough during the initial mix. The herbs develop beautifully during fermentation, adding an aromatic depth that complements grilled meats and roasted vegetables.
I find that fresh rosemary works best—dried can be overpowering. Save a few sprigs to place on top before baking for extra flavor. 🌿
Seeded Crunch Option
Incorporate ¼ cup toasted sesame seeds or poppy seeds into the final dough shape for added texture. These seeds not only add visual appeal but also provide a satisfying crunch that contrasts beautifully with the soft interior.
I recommend lightly toasting the seeds in a dry pan for 2 minutes before mixing to enhance their flavor. Sprinkle them evenly over the dough before the final proof. 🌰
Whole Wheat Adaptation
Replace 1 cup of the all-purpose flour with whole wheat flour for a nuttier, heartier loaf. The whole wheat adds fiber and a slightly denser crumb while maintaining the sandwich bread's structure.
To compensate for the heavier flour, increase the water by 1 tbsp—whole wheat absorbs moisture differently. This version stays fresh longer and adds a rustic charm to your sandwiches. 🌾
Cheesy Pull-Apart Loaf
For a showstopper, fold ½ cup shredded sharp cheddar or Gruyère into the dough after the first rise. The cheese melts during baking, creating pockets of gooey goodness that make every bite irresistible.
I like to sprinkle an extra ¼ cup cheese on top before baking for a golden, bubbly crust. This version is perfect for sharing—just slice while warm. 🧀
Gluten-Free Option
For a gluten-free version, replace the flours with 2 cups gluten-free all-purpose flour blend (like Bob's Red Mill 1:1) and add 1 tbsp xanthan gum to improve structure. Use ½ cup gluten-free oats instead of cornmeal for dusting.
Keep in mind the texture will be slightly denser, but it still delivers that satisfying sandwich bread experience. This adaptation works well for those with gluten sensitivities. 🌱

Frequently asked questions
Why does this recipe use an 8-hour fermentation instead of overnight?
The 8-hour fermentation balances flavor development and texture perfectly for sandwich bread. Overnight fermentation creates more acidity, which can make the bread too tangy for everyday sandwiches. This schedule gives you a mildly tangy, open crumb with just enough fermentation to create that signature sandwich bread texture—soft interior with a crisp crust—without waiting all night.
Can I make this without a Dutch oven?
Yes, but your crust won't be as crackly. Use a heavy oven-safe pot with a lid instead—place the loaf pan inside and cover tightly during the first 30 minutes of baking to trap steam. For extra crunch, sprinkle 1 tbsp cornmeal on top before baking. The texture will be good, just not as dramatic as with a Dutch oven.
How do I know when the dough is ready for shaping?
The dough is ready when it rises 1 inch above the pan during the final proof (45 minutes). It should feel slightly springy when pressed gently with one finger—it should leave a small indentation but spring back quickly. If it doesn't rise enough, let it proof 10-15 minutes longer at room temperature. The dough should be puffy, not dense.
What if my sourdough starter isn't ready?
No problem! Add ¼ tsp instant yeast to the dough during mixing to jumpstart fermentation. The flavor won't be identical, but you'll still get a great sandwich bread. For best results, use your starter within 24 hours of feeding—it should be bubbly and smell slightly sweet/tangy. If it smells like vinegar, feed it 2-3 times before using.
Can I make this in a stand mixer?
Use the dough hook attachment and knead on medium speed for 5-7 minutes until the dough is smooth and elastic. The mixer saves time and ensures even gluten development. Just be careful not to overmix—stop when the dough passes the windowpane test (stretch a piece until it's thin enough to see light through).
