This no-knead App’s Rust sourdough sandwich bread recipe delivers the perfect balance of crispy crust and soft interior—ideal for buttery swirls and even slicing. The secret lies in a slow fermentation that develops flavor while keeping the crumb tender enough for sandwiches.
I’ve refined this recipe over years to ensure reliable results, whether you’re using a homemade starter or store-bought.
The process begins with a hydrated dough that ferments overnight, allowing time for natural leavening and flavor development. A Dutch oven creates steam during baking, giving that signature crackly crust while maintaining a soft, airy interior. The buttery swirls add richness without compromising texture, making every slice perfect for sandwiches.
What sets this apart is the sandwich-specific adjustments: even proofing for consistent slices and controlled baking to prevent over-crisping. No specialized equipment is needed—just patience and attention to fermentation times. The result? A loaf that’s crusty enough to satisfy purists but soft enough to hold fillings without tearing.
Ready in 24 hours total (including overnight fermentation), this recipe is ideal for meal prep or gifting. Here’s how to achieve the perfect sandwich loaf every time.
Ingredients for appsrust sourdough sandwich bread
Fourteen ingredients, twenty-four hours, one perfect sandwich loaf with golden crust and buttery swirls.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| All-Purpose Flour 🌾 | 4 cups | King Arthur or bread flour preferred |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for swirls |
| Granulated Sugar 🍚 | 1 tbsp | For dough nutrition |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Whole Milk 🥛 | ½ cup | Warmed for dough hydration |
| Large Egg 🥚 | 1 whole | Room temperature |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for richness |
| Cornmeal 🌽 | ¼ cup | For Dutch oven dusting |
| Ice Water 💧 | ¼ cup | For dough shaping |
The sourdough starter is your flavor foundation—homemade or store-bought, it needs to be bubbly and active (not flat or sour). I always use King Arthur bread flour for its high protein content, which gives that signature open crumb. For the butter swirls, European-style unsalted butter (like Plugrá) melts beautifully—don’t compromise here. The Diamond Crystal kosher salt is key; it dissolves cleanly and enhances flavor without bitterness. If you’re using a homemade starter, feed it 12 hours before mixing to ensure peak activity.
No Dutch oven? A heavy oven-safe pot with a lid works in a pinch—just add a tray of boiling water below for steam. Swapping milk? Warm water plus 1 tsp powdered milk mimics the fat content. The olive oil can be omitted if you’re strict about butter flavor, but it adds tenderness. For the butter swirls, keep them cold until the final proof—warm butter spreads too much. Need a shortcut? Pre-slice the butter into thin strips before mixing to save time during shaping. The egg is non-negotiable for structure, but if you’re avoiding it, 1 tbsp aquafaba works as a binder (though texture won’t be identical).
This dough is best mixed the night before—fermentation flavors deepen overnight. Store it in a covered bowl at room temp (68-72°F ideal). For the Dutch oven, preheat it with the lid on for 20 minutes before baking to create maximum steam. The loaf keeps well 3-4 days at room temperature wrapped in a clean kitchen towel, or 1 week frozen (slice before freezing for easy serving). Buttery swirls stay freshest if you reheat slices in a toaster—they crisp up beautifully. Double the recipe for two loaves—trust me, you’ll want seconds.

Step-by-step instructions for appsrust sourdough sandwich bread
This no-knead method delivers a crusty exterior with a tender interior and those coveted buttery swirls—every time.
Mix the Dough and Create Buttery Swirls
In a large mixing bowl, combine the 0.5 cup Active Sourdough Starter, 4 cups All-Purpose Flour, 1 tbsp Granulated Sugar, and 1.5 tsp Kosher Salt. Using a wooden spoon or dough whisk, stir until the starter is fully incorporated and the flour forms a shaggy mass with a few small crumbs remaining.
Make a well in the center and add the 0.5 cup Whole Milk, 1 whole Large Egg, and 1 tbsp Olive Oil. Mix vigorously with your hands or a dough whisk until the dough comes together into a sticky, cohesive mass. Avoid overmixing—just enough to combine. Let the dough rest for 5 minutes while you prepare the butter swirls.
Take the 0.5 cup Unsalted Butter (still cold) and cut it into ½-inch cubes. Gently press 4-5 cubes into the dough, spacing them evenly. Fold the dough over the butter pieces, then roll it out into a rough rectangle on a lightly floured surface. Fold it like a letter, then roll again and fold once more. This creates those signature buttery layers. Wrap the dough in plastic wrap and refrigerate for 1 hour—this chilling step is crucial for flavor development and easier handling later.
Shape and Proof the Dough
After the 1-hour rest, turn the dough onto a lightly floured surface and gently shape it into a 12-inch round loaf (about 3 inches thick). Place it seam-side down in a 9-inch cast-iron skillet or Dutch oven that has been dusted with 0.25 cup Cornmeal. The cornmeal prevents sticking and adds a subtle crunch to the crust.
Cover the skillet loosely with plastic wrap and let the dough proof at room temperature for 1-2 hours, or until it has risen to about 1.5 times its original size. You'll know it's ready when the dough has domed noticeably and feels springy to the touch when pressed gently. The proofing time depends on your kitchen's humidity—warmer environments will speed this up.
While the dough proofs, preheat your oven to 450°F with a Dutch oven or heavy baking stone inside. This ensures even heat distribution and that perfect oven spring when the bread bakes. Don't skip this preheating step—it makes all the difference in achieving a crispy crust.
Score and Bake for Maximum Crust
Once the dough has proofed, carefully transfer the skillet to the preheated oven. Immediately score the top of the dough with a sharp razor blade or serrated knife in a crosshatch pattern (about ¼-inch deep). This allows the bread to expand properly and creates those beautiful crust details.
Bake uncovered for 30 minutes at 450°F, then reduce the heat to 375°F and bake for another 25-30 minutes, until the crust is deep golden brown and the internal temperature reaches 190°F when measured with an instant-read thermometer. The bread should sound hollow when tapped on the bottom.
This two-stage baking process is key—high heat initially creates steam for oven spring, while the lower temperature ensures even baking without burning the crust. If the top browns too quickly, tent loosely with foil after the first 15 minutes at 450°F to prevent over-browning.
Cool and Slice for Perfect Texture
Remove the bread from the oven and let it cool in the skillet for 10 minutes, then transfer to a wire rack to cool completely for at least 1 hour. This resting period allows the moisture to redistribute, preventing a gummy crumb. Patience here pays off—slicing too soon results in a dense, uneven texture.
Once fully cooled, slice the bread with a serrated knife and serve. The interior should be tender with those buttery swirls peeking through, while the crust remains crispy enough to hold up to sandwiches. Store any leftovers wrapped in a clean kitchen towel to maintain freshness for up to 3 days at room temperature.
Pro Tips For Making Appsrust Sourdough Sandwich Bread
- STRETCH THE DOUGH: This recipe uses all-purpose flour, which means the dough will be stiffer than with bread flour. Fight the urge to rush—laminate that butter by folding the dough three times (yes, even if it feels like overkill). Each fold should be 30 seconds of gentle pressure, then a 30-second rest. I learned this the hard way when my first batch ended up more "buttery cracker" than sandwich bread.
- SALT THE BUTTER: The recipe calls for unsalted butter, but most home cooks forget to account for the salt in the dough. Taste the butter before mixing—if it’s fresh and bland, add a pinch of kosher salt (about 1/8 tsp per 8 tbsp). I used to skip this, and the finished bread always tasted flat, like it needed something. Turns out, it did.
- DON’T SKIP THE COLD REST: After the final fold, the dough needs to chill for at least 2 hours—no exceptions. I know, I know, you’re eager to bake, but rushing this step means the butter won’t melt evenly, and your layers will turn out greasy instead of flaky. Wrap it tightly in plastic and stash it in the fridge. Your future toast will thank you.
- USE A THIN LAYER: When rolling out the dough, aim for 1/8-inch thickness—not 1/4-inch, not 1/16-inch, but that sweet spot in between. Any thicker, and the butter pools in the center; any thinner, and the bread loses its structure. I measure with a ruler because eyeballing it leads to disappointment. Sounds pedantic, but it works every time.
Essential equipment for great appsrust sourdough sandwich bread
Dutch Oven
Your Dutch oven is the MVP for this recipe—it creates steam during baking for that signature crackly crust while keeping the interior tender. I use a Lodge 5.5-quart cast iron because its thick walls retain heat evenly.
If you don’t own one, a heavy oven-safe pot with a tight-fitting lid works in a pinch. Just preheat it in the oven for 20 minutes before baking to mimic the steam effect. 🔥
Dough Scraper
A stainless steel dough scraper (like the OXO Good Grips or Jamie Geller) is essential for handling this sticky dough. It helps shape the loaf without sticking and makes transferring it to the Dutch oven effortless.
Keep one near your work surface—you’ll use it constantly during shaping and scoring. A flexible silicone scraper also works if you prefer.
Digital Thermometer
An instant-read thermometer (I swear by the Thermoworks Thermapen) ensures your bread bakes to perfection. Check the internal temperature when it reaches 190°F—this guarantees a fully baked loaf without over-crisping.
No thermometer? The tap test works: tap the bottom of the loaf, and if it sounds hollow, it’s done. 🌡️
Bread lame
A sharp bread lame (or a serrated knife) is crucial for scoring. The La Cloche brand is my go-to, but any razor-sharp tool works. Score in a crosshatch pattern (about ¼-inch deep) right before baking to encourage even expansion and that beautiful crust.
A dull knife will tear the dough instead of cleanly scoring it.
Kitchen Scale
While the recipe uses volume measurements, a digital kitchen scale (like the OXO Good Grips) ensures precision, especially for the butter swirls. Weighing ingredients like butter by grams gives you better control over texture and flavor.
For example, 140g of cold butter (instead of eyeballing ½ cup) guarantees consistent results every time. 💡
Wire Rack
Never skip cooling your bread on a wire rack—it prevents sogginess and allows air circulation for that perfect crust. I use a stainless steel rack (like the Nordic Ware) because it’s durable and easy to clean.
If you’re short on space, prop up a rack over a baking sheet to create airflow. Patience here is key—rushing leads to a gummy crumb. ✨

Frequently asked questions
Can I use this recipe with store-bought sourdough starter?
Just ensure your store-bought starter is active and bubbly—not flat or overly sour. Look for brands labeled "ready-to-use" or "discard-friendly" in the refrigerated section. If it's been refrigerated, let it sit at room temperature for 1-2 hours before using to wake it up.
Why does my dough proof too quickly or not at all?
Proofing depends on your kitchen's temperature and humidity. Ideal conditions are 75-78°F with moderate humidity. If it proofs too fast, try refrigerating it for 12-24 hours first. If it's sluggish, place the bowl over a pan of warm water (not touching) to gently increase temperature. Warmth speeds fermentation, but never exceed 80°F or the dough may overproof.
How do I fix a dense or gummy sandwich bread?
Dense bread usually means overmixing or underproofing. For next time, mix just until combined and let the dough rest longer during proofing. If it's gummy, your bread likely cooled too quickly—always let it rest on a wire rack for at least 1 hour before slicing. Pro tip: A 190°F internal temp guarantees doneness, not just appearance.
Can I make this recipe without a Dutch oven?
Yes! Use a heavy oven-safe pot with a lid (like a Le Creuset) or even a baking stone with a steam tray. For best results, preheat the pot in the oven for 20 minutes before baking. Add a tray of boiling water below for steam. The crust won't be as crackly, but the texture will still be excellent.
How should I store leftovers to keep them fresh?
Wrap cooled slices in a clean kitchen towel (not plastic) and store at room temperature for 2-3 days. For longer storage, freeze slices individually on a tray, then transfer to a bag. Toast before serving to revive crispiness. The towel method preserves moisture better than plastic wrap.
