Side Dishes
This all-purpose flour sourdough sandwich bread delivers the perfect balance of crispy-crusted edges and a soft, airy interior—ideal for buttery toast or hearty sandwiches. The beauty of this recipe lies in its simplicity: no expensive ingredients or complicated techniques, just a 24-hour process that transforms basic flour into restaurant-quality bread.
I’ve perfected this method after years of baking, ensuring every slice holds its shape and packs maximum flavor.
The secret to achieving that crispy crust while keeping the center tender starts with a well-fed sourdough starter and precise fermentation times. Unlike artisanal sourdough, this version uses all-purpose flour for a lighter texture, making it perfect for everyday meals.
Bulk fermentation and a gentle shaping technique create the signature open crumb structure, while baking in a Dutch oven traps steam for an oven-spring that’s impossible to resist.
By the time you pull that golden loaf from the oven, you’ll have a bread that’s crisp enough to hold up to thick sandwich fillings yet soft enough to melt in your mouth. The aroma alone—warm, tangy, and slightly sweet—will have everyone at the table asking for seconds.
This isn’t just bread; it’s a foolproof way to elevate any meal, whether it’s breakfast toast or a classic BLT.
Best of all, this recipe scales perfectly for meal prep or gifting. Make a double batch and freeze slices for fresh-baked sandwiches anytime. Here’s how to create it from scratch—no experience required.
Ingredients for all purpose flour sourdough sandwich bread
Eight simple ingredients crafting restaurant-quality sandwich bread at home.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 5 cups | Bread flour for better structure (optional) |
| Active Sourdough Starter 🍞 | 2 cups | 100% hydration, bubbly and active |
| Granulated Sugar 🍚 | ¼ cup | White sugar for balanced sweetness |
| Salt 🧂 | 2 tsp | Diamond Crystal kosher preferred |
| Water 💧 | 2 ½ cups | Lukewarm, filtered preferred |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for richness |
| Instant Yeast 🍞 | ¼ tsp | Optional for extra lift |
| Cornmeal 🌽 | ¼ cup | For dusting Dutch oven |
The sourdough starter is the heart of this recipe—look for a bubbly, active starter that doubles in size within 4-6 hours. King Arthur or Bob's Red Mill flours create the perfect light crumb, but all-purpose works too. For the starter, I always use a 100% hydration ratio (equal parts flour and water) because it's foolproof. If your starter smells tangy but isn't bubbly, feed it with extra flour and wait another hour. The sugar and yeast combo here gives that subtle sweetness without overpowering the sourdough tang—think of it as a flavor enhancer, not a primary sweetener.
No instant yeast? Double the amount of active dry yeast (but account for the extra 10 minutes it needs to activate). Running low on olive oil? Melted coconut oil works perfectly—just don't use butter, or the crust will darken too quickly. The cornmeal isn't just for dusting—it creates that golden crust when baked. For a crispier crust, sprinkle extra cornmeal on top before baking. And if you're making this ahead, freeze the shaped loaf before baking—it keeps for up to 3 months and bakes straight from frozen (add 10-15 minutes).
This dough keeps for 24 hours in the fridge if you need to slow down fermentation—just bring it to room temp before shaping. For maximum crispiness, bake immediately after shaping. The Dutch oven is non-negotiable here—no substitutes—it traps steam for that perfect oven spring. If you don't have one, use a heavy pot with a lid. Store wrapped at room temp for 2-3 days or freeze slices for up to 3 months. The bread actually improves overnight—trust me on this—as the crumb firms up and the crust crisps further.
Why You'll Love This Recipe
- Pantry-Friendly Magic: I swear by this recipe because it turns my basic pantry staples—just flour, starter, sugar, and water—into something that tastes like a bakery’s secret. No fancy ingredients, no stress, just pure, tangy satisfaction with zero fuss.
- Tangy Twist: That sourdough starter? It’s the star. The slow fermentation gives it a depth you won’t find in store-bought bread—like a warm, chewy hug with a hint of sour that makes every bite feel intentional. (And yes, it’s still soft enough for sandwiches.)
- Weeknight Workhorse: Between us, this is my go-to for lunchboxes, charcuterie boards, or even a quick toast with butter. It holds up to grilled cheese, PB&J, or just buttered slices—no sad, squished sandwiches here. Honestly, I’ve made it three times this week already.
- Budget Bread: A loaf costs me pennies compared to buying artisanal bread, and it lasts forever. Freeze slices for toast later, or stash the whole loaf—it stays fresh for days. My wallet and my taste buds win every time.
Step-by-step instructions for all-purpose flour sourdough sandwich bread
Here's how to craft a sandwich bread with a crackling crust and tender crumb—no fancy equipment needed.
Mix the Dough and Let It Rest
In a large mixing bowl, combine the 5 cups all-purpose flour, 2 cups active sourdough starter, 0.25 cup granulated sugar, 2 tsp salt, and 0.25 tsp instant yeast. Mix just until combined—you'll see dry spots, and that's perfect. Add the 2.5 cups lukewarm water and 1 tbsp olive oil, then stir until a shaggy dough forms.
Turn the dough out onto a lightly floured surface and knead for 5-7 minutes until smooth and elastic. The dough should feel slightly tacky but not sticky. If it's too dry, add 1 tsp water at a time until it reaches the right consistency. Place the dough in a lightly oiled bowl, cover with a damp towel, and let it rest at room temperature for 1 hour. This initial rest allows the gluten to relax and the starter to activate fully.
Bulk Ferment for Maximum Flavor
After the initial rest, the dough should have risen slightly and feel puffy. Punch it down gently to release air, then transfer it to a clean bowl. Cover again and let it ferment at room temperature for 4-6 hours, or until it has roughly doubled in size. You'll know it's ready when the dough springs back slowly when poked—this means the gluten has developed properly and the starter has done its magic.
I like to check the dough every hour after the first 2 hours. If it rises too quickly, place it in the fridge to slow fermentation slightly. The goal is a slow, controlled rise for deep flavor and an open crumb structure. The longer it ferments, the more complex the flavor becomes—just don't let it overproof or collapse.
Shape and Final Proof
Lightly flour a surface and turn out the dough. Gently shape it into a rectangle about 8x10 inches, then fold one long side toward the center, followed by the opposite side. Rotate the dough a quarter turn and repeat, creating a tight, rectangular loaf. This technique, called a "fold and roll," helps develop tension in the dough for an even rise.
Place the shaped dough seam-side up in a 9x5-inch loaf pan that's been lightly greased with olive oil. Cover loosely with plastic wrap and let it proof at room temperature for 1-2 hours, or until it rises 1-2 inches above the pan. The dough should feel springy when pressed lightly—this is your cue that it's ready for the oven.
Bake for a Crispy Crust and Soft Crumb
Preheat your oven to 375°F. Sprinkle the 0.25 cup cornmeal evenly over the dough in the pan—this creates a crispy bottom crust and prevents sticking. Bake for 30-35 minutes, until the top is deep golden brown and the internal temperature reaches 190°F. Tap the loaf gently—the crust should sound hollow, indicating a fully baked crumb.
Here's the thing—don't open the oven door during the first 20 minutes of baking. The steam trapped inside creates that perfect oven spring and crispy crust. If the top browns too quickly, tent the loaf with aluminum foil. Once baked, transfer the bread to a wire rack to cool completely before slicing—this prevents a gummy texture and lets the crumb set properly.
Pro Tips For Making All Purpose Flour Sourdough Sandwich Bread
- Weigh Your Starter Precisely: I learned this the hard way—eyeballing sourdough starter leads to dense, gummy bread. Use a scale for the starter (usually 10-15% of flour weight) to guarantee consistent fermentation. A 100g starter for 1000g flour works reliably, and your dough will thank you with proper rise.
- Autolyse First—Seriously: Skip the immediate mixing of salt and starter. Let the flour and water sit alone for 30-60 minutes first (this is autolyse). It develops gluten more evenly, and your kneading or stretching later becomes a breeze. I used to rush this, and my sandwich bread always felt tougher afterward.
- Steam the First 10 Minutes: Your oven’s broiler or a metal tray of boiling water under the dough makes all the difference for crust. Without it, all-purpose flour bread turns out flat and pale. Crank the oven to 450°F (230°C), add steam right when loading the dough, then reduce to 375°F (190°C) for the remaining bake.
- Use Cold Water for Dough: I was skeptical until I tried it—cold water (around 60°F/15°C) slows fermentation just enough to give you control. Your dough will rise predictably overnight, and the flavor develops more evenly. No more guessing if it’s ready or overproofed. (Yes, even if you’re impatient like me.)
Creative variations of this recipe
Sweet & Savory Twist
Add 1 tsp cinnamon and ½ tsp cardamom to the dough for a subtle sweetness that pairs perfectly with peanut butter or jam sandwiches. I like to brush the baked loaf with a mix of 1 tbsp honey and ½ tbsp melted butter for extra richness.
This variation works especially well with all-purpose flour because it balances the tangy sourdough flavor without overpowering it. 🍯
Seeded & Nutty Boost
Stir in ¼ cup toasted sesame seeds or chopped walnuts during the final proof for added texture and crunch. For a heartier loaf, fold in 2 tbsp sunflower seeds or pumpkin seeds—they add a nutty depth that complements sandwiches with avocado or hummus.
I recommend toasting the seeds first to enhance their flavor and prevent them from sinking to the bottom during baking.
Herb-Infused Variety
Mix in 1 tbsp fresh rosemary or thyme leaves (finely chopped) for an aromatic twist that elevates sandwiches with roasted meats or cheeses. For a Mediterranean touch, add 1 tsp dried oregano and ½ tsp garlic powder.
These herbs work beautifully with the all-purpose flour base, creating a lighter, more fragrant loaf. Just be sure to distribute them evenly throughout the dough before shaping.
Whole Grain Swap
Replace 1 cup of the all-purpose flour with whole wheat flour or spelt flour for a nuttier, denser loaf that still holds up well for sandwiches. I prefer King Arthur whole wheat flour because it blends seamlessly without making the dough too sticky.
This variation adds fiber and a deeper flavor, perfect for hearty fillings like grilled chicken or smoked salmon. Adjust the water slightly if the dough feels too dry.
Cheesy Pull-Apart Loaf
Fold in ½ cup shredded cheddar cheese or mozzarella during the final proof for a gooey, pull-apart texture. This works best with a slightly shorter proof (1 hour) to prevent the cheese from melting too early.
The result? A sandwich bread with pockets of melted cheese that add richness to every bite. I love this version for breakfast sandwiches or as a side with soups. 🧀
Gluten-Free Adaptation
For a gluten-free version, replace the all-purpose flour with 1:1 gluten-free baking flour (like Bob's Red Mill) and add 1 tsp xanthan gum to improve structure. Use 1.5 tsp instant yeast to ensure proper rise, and let the dough ferment for an extra 30 minutes to develop flavor.
The texture will be slightly denser but still perfect for sandwiches. This adaptation proves you don’t need gluten for a delicious loaf! 🌾

Frequently asked questions
Can I use this recipe without a sourdough starter?
Yes! If you don't have an active starter, substitute the 2 cups sourdough starter with 2 cups warm water and 1 tsp instant yeast (or 2 ¼ tsp active dry yeast). The flavor will be milder but still delicious—perfect for beginners.
Why does my dough smell like alcohol?
That's normal! The sourdough starter produces lactic and acetic acids during fermentation, which create a tangy aroma and slight alcohol smell. If the smell is overly sharp or vinegary, your starter may need refreshing. A well-fed starter should have a pleasant, slightly sweet tang—not a harsh sourness.
How do I know when the bread is fully baked?
The bread is done when the internal temperature reaches 190°F and the crust sounds hollow when tapped. For visual cues, look for a deep golden brown color. If unsure, bake 5 more minutes—underbaked bread can feel gummy.
Can I make this in a Dutch oven instead of a loaf pan?
Shape the dough into a round boule or batard, place it in a hot Dutch oven with cornmeal, and bake covered for 20 minutes before uncovering. This creates a crispy crust with an open crumb—ideal for sandwiches. Just reduce baking time by 5-10 minutes compared to the loaf pan method.
Why did my bread turn out dense instead of light?
Dense bread usually means overproofing (fermented too long) or underproofing (not enough time). Check your dough's readiness by pressing gently—it should spring back slowly. Also ensure you're using all-purpose flour (not cake flour) and that your yeast/starter is active. A cold environment slows fermentation, so adjust times if your kitchen is chilly.
