All-Purpose Flour Sourdough Sandwich Bread Recipe: Artisan Crust With No-Knead Ease

This all-purpose flour sourdough sandwich bread delivers artisan-quality crust and a light, airy crumb—without the complexity of traditional sourdough. The secret lies in a no-knead method that simplifies fermentation while developing deep flavor, making it perfect for home bakers who want restaurant-worthy results with minimal effort.

I've perfected this recipe after years of testing, ensuring every slice has that signature open crumb and crisp exterior that makes sandwiches irresistible.

The beauty of this recipe is its versatility—it uses all-purpose flour for approachability while still capturing sourdough's signature tang and texture. We'll start with a simple starter (or use a pre-made one), then focus on controlled fermentation to develop flavor without overproofing.

The shaping technique creates those classic sandwich bread dimensions, while strategic scoring ensures an even rise and beautiful oven spring. No special equipment is needed beyond a mixing bowl and baking sheet.

What you'll end up with is bread that's ideal for toast, sandwiches, or French toast—with a crisp crust that gives way to a tender, slightly chewy crumb. The flavor develops over time, making it even better the next day as the starches convert.

This recipe transforms a basic pantry staple into something special, proving that great bread doesn't require complicated techniques or expensive ingredients.

Perfect for meal prep or serving fresh, this sourdough sandwich bread keeps well for 5-7 days at room temperature or can be frozen for up to 3 months.

The no-knead method means less work for you, while the all-purpose flour ensures consistent results even if you're new to sourdough baking. Let's get started on creating your perfect loaf.

Ingredients for all purpose flour sourdough sandwich bread

Four cups of flour kickstart this sourdough transformation—artisan crust, no-knead magic.

The flour is your foundation, so King Arthur or Gold Medal is ideal—they handle hydration beautifully without gummy results. Bulk bins at Whole Foods or King Arthur's website are great sources. For the yeast, always check the expiration date—it's the heart of your rise. The sourdough starter can be homemade (I'll link my easy starter guide) or grabbed from a local bakery if you're impatient. Just make sure it's bubbly and active, not flat. The butter should be cold—this creates pockets of steam during baking for that signature open crumb. Plugrá or Land O'Lakes work perfectly, but avoid salted varieties.

No sourdough starter? Instant yeast at double the amount gets you close, though the flavor won't be quite the same. Running short on cornmeal? Semolina or all-purpose flour works in a pinch. The egg wash is optional but gives that golden finish—omit if vegan. For the sesame seeds, Trader Joe's has the best prices, but any store's bulk section will do. Want extra flavor? Swap half the flour for whole wheat—just add 1 extra tbsp of water to compensate. The butter can be substituted with vegetable shortening if you're avoiding dairy, though the flavor won't be identical.

This dough keeps in the fridge for 24 hours before shaping—perfect for overnight prep. Once baked, let it cool completely on a wire rack (at least 1 hour) to prevent sogginess. Store wrapped at room temperature for 5-7 days—it actually improves as the starches convert! For longer storage, slice and freeze portions for 3 months. The crust stays crisp for about 2 days, so toast fresh slices for maximum enjoyment. I always make a double batch—the extra loaf disappears faster than you'd think!

Step-by-step instructions for artisan sourdough sandwich bread

Here's how to craft a perfect loaf with an irresistible crust and tender crumb—no kneading required.

In a large mixing bowl, combine the 0.5 cup sourdough starter with the 1.5 cups warm water (105°F) and 1 tbsp granulated sugar. Let this sit for 10-15 minutes until you see bubbles forming at the surface—this confirms your starter is active and ready to work. While waiting, cut the 0.5 cup unsalted butter into small cubes and set aside.

After the starter bubbles, add the cold butter cubes to the bowl and gently mix with a wooden spoon until the butter melts and incorporates completely. The mixture should look like a thick, creamy paste. This butter creates the signature tender crumb and crisp crust that makes this bread so special. If you're using a stand mixer, attach the paddle attachment and mix on low speed for 1 minute to fully emulsify the butter.

In a separate bowl, whisk together the 4 cups all-purpose flour and 1.5 tsp salt. Sift the mixture into the butter mixture, then add the 1 whole large egg. Using a wooden spoon or your hands, mix until a shaggy dough begins to form. The dough will be sticky—this is normal and expected with sourdough.

Transfer the dough to a lightly greased bowl, cover with a damp kitchen towel, and let it rest at room temperature for 1 hour. This initial rest allows the gluten to relax and the dough to develop flavor. After 30 minutes, gently stretch and fold the dough by grabbing one side, pulling it upward, and folding it over itself. Repeat this process on all four sides—this builds structure without kneading.

After the 1-hour rest, turn the dough out onto a surface lightly dusted with the 0.25 cup cornmeal. Shape it into a round boule by pulling the edges toward the center and tucking them underneath. Place the boule seam-side up on a parchment-lined baking sheet, cover with a damp towel, and let it proof at room temperature for 1-2 hours until it has nearly doubled in size and feels light when pressed gently.

Here's where the magic happens: the dough should spring back slowly when poked with your finger, and you should see bubbles forming on the surface. If your kitchen is cool (below 70°F), you may need to extend this proofing time. The goal is a dough that's ready to bake but still has some resistance—this ensures a good oven spring when it hits the heat.

Preheat your oven to 425°F with a baking stone or inverted baking sheet on the middle rack. Place a metal bowl filled with 1 cup hot water on the lower rack—this creates steam during baking, which gives you that beautiful, crisp crust. Once the oven is fully preheated, carefully transfer the dough (on its parchment) to the baking stone.

Bake for 25-30 minutes until the bread reaches an internal temperature of 205°F and the crust is a deep golden brown. You'll know it's done when it sounds hollow when tapped on the bottom. If the top browns too quickly, tent the bread with aluminum foil for the last 10 minutes of baking.

Remove the bread from the oven and let it cool on a wire rack for at least 30 minutes before slicing. This resting period allows the crumb to set and prevents a gummy texture. While the bread cools, beat the 1 whole large egg in a small bowl and brush it lightly over the top of the loaf for a glossy finish.

Sprinkle the 1 tbsp sesame seeds evenly over the egg wash, pressing them gently into the crust. These seeds add a subtle nutty flavor and beautiful contrast to the golden crust. Once fully cooled, slice the bread into ½-inch thick sandwich slices. Each slice should have a crisp, crackly exterior with a soft, airy interior—perfect for holding fillings without falling apart.

Essential equipment for this recipe

Mixing Essentials

Start with a large mixing bowl—I recommend a stainless steel bowl (like OXO Good Grips) for durability and easy cleanup. For mixing, use a wooden spoon or damp hands to handle the sticky dough without sticking.

A stand mixer with a paddle attachment works beautifully if you prefer hands-off mixing, but it's not required. 🌾

Proofing Tools

For proofing, a damp kitchen towel or plastic wrap keeps the dough moist without drying out. I love using parchment-lined baking sheets (from Amazon Basics) to prevent sticking during shaping.

A digital kitchen scale (like OXO Good Grips) ensures precise measurements for the starter and flour—critical for consistent results.

Baking Setup

Preheat your oven with a baking stone or inverted baking sheet on the middle rack for even heat distribution. A steam pan (a metal bowl filled with 1 cup hot water) on the lower rack creates that signature crisp crust.

I use a thermometer (like Thermoworks Smoke) to monitor the dough's internal temperature—205°F is perfect for a golden crust.

Cooling and Storing

Always let bread cool on a wire rack (I prefer OXO Good Grips) to prevent sogginess. For storage, use airtight containers (like Rubbermaid) to maintain freshness. A sharp bread knife (like German-style from Zwilling) ensures clean slices without crushing the crumb. 💡

Optional Extras

An egg wash brush (like Silpat) makes applying the egg wash effortless. For scoring, a lame (like La Cloche) gives professional-looking cuts. If you're ambitious, a proofing box (like Breville) controls humidity and temperature for perfect rises—though it's not essential for beginners.
