Side Dishes
This all-purpose flour sourdough sandwich bread delivers restaurant-quality texture with minimal effort—think soft, sliceable crust perfect for BLTs or grilled cheese. The secret lies in a no-knead method that develops deep flavor while keeping the dough manageable for home bakers.
I've perfected this recipe after years of experimenting, and it consistently yields bread with an open crumb and just enough chew to hold sandwich fillings without overpowering them.
The process begins with an autolyse to hydrate the flour fully, followed by a simple mix-in of sourdough starter and salt. Unlike traditional sourdough, this version uses all-purpose flour for reliability while still capturing that signature tang and airy texture.
Fermentation happens overnight in the fridge, allowing time for flavor development without the risk of overproofing—ideal for busy schedules.
Baking creates a golden, crackly crust with a soft interior that stays fresh for days, making it perfect for sandwiches. The bread slices cleanly, holds shape when toasted, and absorbs fillings beautifully. Whether you're making classic PB&J or gourmet paninis, this loaf elevates every bite without requiring advanced skills.
For variations, try adding whole wheat flour (replace 20% of all-purpose) for nuttiness or mixing in dried herbs during autolyse for savory notes. The recipe scales perfectly for two loaves, and leftovers freeze beautifully. Ready to bake bread that tastes homemade but requires less effort than store-bought?
Ingredients for all purpose flour sourdough sandwich bread
Nine essential ingredients transform simple pantry staples into artisanal sandwich bread with minimal effort.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 cups | King Arthur or Gold Medal preferred |
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| Granulated Sugar 🍚 | ¼ cup | For balanced sweetness |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Water 💧 | 1 ½ cups | Room temperature, 70°F |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for mixing |
| Cornmeal 🌽 | ¼ cup | For dusting loaf pans |
| Large Egg 🥚 | 1 whole | For egg wash |
| Whole Milk 🥛 | 1 tbsp | For egg wash richness |
The all-purpose flour is non-negotiable here—King Arthur or Gold Medal develop gluten beautifully without the wait of bread flour. Your sourdough starter needs to be active (bubbly, 100% hydration)—if it's sluggish, feed it 1:1:1 (flour:water:starter) by weight 4-6 hours before using. Whole Foods or local bakeries often sell reliable starter cultures if you're starting from scratch. The butter adds tenderness; Plugrá or Land O'Lakes unsalted work best when cold-cubed for even distribution. Room temperature water is critical—cold slows hydration, hot kills yeast activity.
No sourdough starter? Instant yeast at 0.25 tsp works in a pinch, though flavor won't be identical. Substitute whole wheat flour by replacing 20% of the all-purpose (up to 0.8 cups) for nuttiness, but expect slightly denser crumb. The sugar balances acidity—turbinado or brown sugar adds depth if you prefer caramel notes. Diamond Crystal salt dissolves cleaner than Morton; if using Morton, reduce by 0.25 tsp. For the egg wash, pasteurized eggs prevent salmonella risk without sacrificing richness. Store-bought milk works, but whole milk yields a glossier crust.
Pre-mixed dough keeps for 24 hours in the fridge, but flavor peaks after overnight cold fermentation. Shape loaves immediately after mixing to avoid overhandling. For make-ahead convenience, portion dough into 2 one-pound balls, wrap tightly in plastic, and freeze for up to 3 months. Thaw overnight in the fridge before baking. The crust stays crisp for 3 days at room temperature when wrapped in a clean kitchen towel; slice and toast within 5 days for peak texture. Leftovers freeze beautifully—wrap individual slices in parchment before freezing for sandwich-ready portions.

Step-by-step instructions for all-purpose flour sourdough sandwich bread
This method delivers a crisp artisan crust and tender crumb with minimal effort—perfect for sandwiches.
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, and 1.5 tsp salt. Create a well in the center and gradually add the 1.5 cups room-temperature water, mixing with a wooden spoon until just combined. The dough will be shaggy but cohesive.
Next, add the 0.25 cup cold cubed unsalted butter and mix until fully incorporated. Cover the bowl with a damp kitchen towel and let rest at room temperature for 30 minutes. This initial rest allows the gluten to relax, making the dough easier to handle later. After resting, fold the dough over itself 3-4 times to develop structure without overworking it.
Shape and Proof for Ideal Rise
Lightly flour a clean surface and transfer the dough. Gently shape it into a loose oval, tucking the edges underneath. Place the dough seam-side up in a greased 9x5-inch loaf pan, dusting the top with 0.25 cup cornmeal to prevent sticking. Cover loosely with plastic wrap and let proof at room temperature for 1-2 hours or until the dough has risen about 50% and springs back slowly when pressed.
Here's the thing—don't rush this step. The longer the proof, the more flavorful the bread. If your kitchen is warm, reduce proofing time slightly to avoid overproofing, which leads to a dense crumb. The dough is ready when it fills about 75% of the pan's height and leaves a gentle finger indentation that fills slowly.
Bake for a Crisp Crust and Even Crumb
Preheat your oven to 375°F with a baking stone or inverted baking sheet on the middle rack. Create an egg wash by beating the 1 whole large egg with 1 tbsp whole milk in a small bowl. Brush this generously over the proofed dough, focusing on the top and sides. The egg wash enhances browning and adds shine.
Bake the bread for 35-40 minutes until the internal temperature reaches 190-200°F and the crust is deep golden brown with a crisp texture. Tap the bottom of the loaf—it should sound hollow. If the top browns too quickly, tent loosely with aluminum foil during the last 10 minutes of baking to prevent over-browning while ensuring even doneness.
Cool and Slice for Perfect Sandwich Bread
Remove the bread from the pan and place it on a wire rack to cool completely for at least 1 hour. This resting period is crucial—skipping it results in a gummy crumb. The bread will firm up as it cools, making it easier to slice without smashing.
Use a sharp serrated knife to slice the cooled loaf into ½-inch thick slices. The exterior should be crisp with a crackly crust, while the interior reveals an open, airy crumb perfect for sandwiches. Store wrapped at room temperature for up to 3 days or freeze slices for longer storage. The flavor improves over time as the crust continues to develop character.
Pro Tips For Making All Purpose Flour Sourdough Sandwich Bread
- Weigh Your Starter: Skip the eyeballing—use a kitchen scale to measure your active sourdough starter. A 100% hydration starter (equal parts flour and water by weight) should be around 100-120g for this recipe, depending on your batch size. I learned this the hard way when my loaves turned dense because I guessed the starter amount.
- Autolyse First: Mix the all-purpose flour and water (about 60% hydration for sandwich bread) and let it sit for 30-60 minutes before adding starter, sugar, and salt. This step hydrates the flour properly and makes kneading easier—no, it won’t replace proper mixing, but it gives the gluten time to relax.
- Skip the Over-Kneading: All-purpose flour develops gluten faster than bread flour, so resist the urge to knead like you’re trying to win a tug-of-war. After autolyse, do just 3-5 minutes of gentle stretching and folding during bulk fermentation—overworking it makes the bread tough.
- Steam the Oven: Place a metal tray on the bottom rack of your oven and fill it with boiling water 10 minutes before baking. The steam helps create that crisp crust without burning the outside. I used to skip this and ended up with dry, sad sandwich bread—don’t make my mistake.
Best sauces and condiments for this dish
Classic Garlic Butter
This is my go-to for sandwiches—melt 2 tbsp unsalted butter with 1 minced garlic clove and ½ tsp lemon juice until bubbly. Spread warmly on toasted slices for a rich, aromatic base that pairs perfectly with grilled meats or avocado.
For extra depth, add a pinch of Penzeys smoked paprika while melting. 🧄
Spicy Sriracha Mayo
Mix ¼ cup mayonnaise with 1 tbsp sriracha and 1 tsp honey until smooth. This adds a tangy kick that cuts through rich fillings like pulled pork or fried chicken.
I like to add a dash of Worcestershire sauce for umami complexity. Spread on sandwiches just before serving to prevent sogginess.
Honey Mustard
Whisk together 2 tbsp Dijon mustard, 1 tbsp honey, and 1 tsp apple cider vinegar for a sweet-tangy glaze. This works wonders with turkey or roast beef sandwiches.
For a smoother texture, thin with 1 tsp water if needed. The honey softens the crust while the mustard adds depth.
Avocado Lime Crema
Blend ½ ripe avocado, 2 tbsp sour cream, 1 tbsp lime juice, and ¼ tsp salt until creamy. This adds a luxurious, fresh element to veggie sandwiches or wraps.
For extra richness, stir in 1 tbsp crumbled feta cheese before serving. Use within 2 hours of making to prevent browning.
Pesto Spread
Store-bought pesto works, but I prefer homemade: blend 1 cup basil, ¼ cup pine nuts, 1 garlic clove, ¼ cup olive oil, and ¼ cup grated Parmesan until smooth.
Thin with 1 tbsp water if needed. This pairs beautifully with prosciutto, mozzarella, and tomato sandwiches. Add a pinch of red pepper flakes for heat.
Spicy BBQ Glaze
Simmer ½ cup BBQ sauce (I love Sweet Baby Ray's) with 1 tbsp hot sauce and 1 tsp brown sugar for 5 minutes until slightly thickened.
Brush on toasted bread before assembling for a smoky, sweet contrast. Perfect for pulled pork or chicken sandwiches—add extra sauce for dipping on the side. 🔥

Frequently asked questions
Can I use this recipe with store-bought sourdough starter?
Yes, but check it's active first! Your starter should have visible bubbles and float in water. If it's sluggish, feed it 1:1:1 (flour:water:starter) by weight 4-6 hours before using. For best flavor, use a well-established starter (at least 2 weeks old) that's been fed regularly. Pro tip: Store-bought starters often contain additives that may affect fermentation time.
Why does my dough look too sticky after mixing?
This is normal! The dough should be shaggy and tacky when first mixed—it's designed this way for optimal texture. If it's extremely sticky, try adding 1-2 tbsp more flour during shaping, but don't overdo it or the bread will become dense. The butter in the recipe helps create a tender crumb, so resist the urge to add extra flour during mixing. The dough will firm up significantly during the 30-minute rest before shaping.
How do I know when the bread is fully baked?
Look for three signs: the internal temperature should reach 190-200°F, the crust should be deep golden brown with crisp spots, and tapping the bottom should sound hollow. If the top browns too quickly, tent loosely with foil for the last 10 minutes of baking. The bread will continue cooking slightly after removal, so pull it out when it's just slightly underdone.
Can I make this bread without a loaf pan?
Shape the dough into a round boule or batard instead. For a boule, create a tight ball with the seam side down on a parchment-lined baking sheet. For a batard, shape into an oval log. Bake at 375°F for 30-35 minutes until the crust is crisp and golden. The crust will be thicker on the bottom, but the interior will remain soft and perfect for sandwiches.
Why does my bread taste bland?
Bland flavor usually means underproofed dough or weak fermentation. Let the dough proof longer (up to 3 hours at room temperature) for deeper flavor development. Also check your starter—it should be active and tangy. For extra flavor, try adding 1 tsp dried rosemary or ½ tsp garlic powder during the autolyse stage. The sugar in the recipe helps balance acidity, so don't skip it.
