Ingredients for appsrust sourdough sandwich bread
Nine ingredients, one game-changing trick—this sourdough delivers restaurant-quality sandwich bread every time.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | Fed and bubbly, 100% hydration |
| All-Purpose Flour 🌾 | 4 cups | King Arthur or similar |
| Unbleached Bread Flour 🌾 | 1 cup | For better structure |
| Granulated Sugar 🍚 | ¼ cup | White or light brown |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred |
| Water 💧 | 1 ½ cups | Lukewarm, 90°F |
| Olive Oil 🫒 | 1 tbsp | Extra-virgin for flavor |
| Aluminum Foil 📄 | 1 sheet | Heavy-duty, 15x20 inches |
| Cornmeal 🌽 | ¼ cup | For dusting loaf pan |
| Ice Water ❄️ | ½ cup | For shaping dough |
| Egg Wash 🥚 | 1 whole | Beaten with 1 tbsp water |
| Coarse Sea Salt 🧂 | 1 tsp | For sprinkling crust |
The sourdough starter is non-negotiable—it's what gives this bread its signature tang and open crumb. King Arthur's sourdough starter is my go-to if you're just starting, but any active, bubbly starter will work. Feed yours 12-24 hours before baking so it's at peak strength. The flour mix matters too: all-purpose gives structure while bread flour boosts gluten development. Bob's Red Mill has great options if you're buying in bulk. Don't skimp on the salt—Diamond Crystal dissolves better than table salt, and you'll notice the difference in flavor.
No sourdough starter? Instant yeast at half the amount (1/4 tsp) gets you close, though the flavor won't be quite the same. Running short on bread flour? All-purpose plus 1 tbsp vital wheat gluten works in a pinch. The olive oil adds richness—Trader Joe's extra-virgin is my secret weapon. For the foil trick, heavy-duty foil is key—Reynolds works perfectly. The ice water helps tighten the gluten during shaping, so don't skip it. Pro tip: if your kitchen gets warm, chill the dough 1 hour before shaping to prevent overproofing.
This dough is a patient recipe—plan for 12-16 hours including fermentation. Shape the loaf in a 9x5-inch loaf pan lined with parchment paper for easy removal. The foil trick creates that signature crust: place the dough on foil, fold it up like a pouch, then bake. Store wrapped at room temp for 3 days or freeze for 3 months. For sandwiches, slice with a serrated knife—it gives cleaner cuts. Leftovers? Toast them—they taste even better the next day!

Step-by-step instructions for Appsrust sourdough sandwich bread
This no-knead method delivers bakery-style sandwich bread with crispy crust and airy layers—no fancy equipment needed!
Mix the Dough with Wet and Dry Ingredients
In a large bowl, combine the 0.5 cup Active Sourdough Starter, 1.5 cups Water, 1 tbsp Olive Oil, 0.25 cup Granulated Sugar, 1.5 tsp Salt, 4 cups All-Purpose Flour, and 1 cup Unbleached Bread Flour. I like to use a wooden spoon first to break up any dry bits before mixing thoroughly with my hands.
Once everything comes together, the dough will be sticky but manageable. Real talk: it’s okay if it looks messy—this is a wet dough that relies on the foil trick for structure. Let it rest for 10 minutes while you prep your work surface with the 0.25 cup Cornmeal. This resting time helps the flour absorb the liquid and makes shaping easier later.
Shape and Seal the Dough in Foil
Lightly dust a clean work surface with the 0.25 cup Cornmeal and turn out the dough. Gently shape it into a loose log about 12 inches long—don’t stress about perfect seams. The magic happens when you wrap it tightly in the 1 sheet Aluminum Foil, sealing all edges completely. This creates a steam chamber that develops that signature crusty exterior and pillowy interior.
Place the foil-wrapped dough seam-side down in a 9x5-inch loaf pan (or similar). The foil should extend about 2 inches above the pan’s rim—this is what will puff up during baking. Let it rest at room temperature for 1 hour, covered loosely with a kitchen towel. This step ensures even oven expansion and prevents cracking.
Preheat and Bake with the Foil Trick
Preheat your oven to 375°F while the dough rests. When ready, carefully remove the foil from the dough and slide it back into the pan. Here’s the key: do not unwrap it completely—leave about 1 inch of foil covering the top. This creates a controlled steam environment that gives you that perfect crust without burning.
Bake for 40-45 minutes until the top is deep golden brown and the internal temperature reaches 190°F. You’ll know it’s done when you tap the bottom—it should sound hollow. If the crust browns too quickly, tent loosely with foil for the last 10 minutes to prevent over-browning.
Finish with Egg Wash and Coarse Salt
Remove the bread from the oven and immediately brush the top with the 1 whole Egg Wash (beaten egg + 1 tbsp water). Sprinkle generously with 1 tsp Coarse Sea Salt while the crust is still warm—this adds texture and flavor. Return to the oven for 3-5 minutes to set the egg wash and develop that glossy finish.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack. This resting time is crucial—it allows the crumb to set properly and prevents a gummy texture. Slice after 1 hour for clean layers and maximum sandwich potential. The result? A crusty exterior with a soft, open crumb perfect for grilled cheese or BLTs!
Pro Tips For Making Appsrust Sourdough Sandwich Bread
- STRETCH AND FOLD: The recipe calls for a long bulk ferment, but I learned the hard way—skipping the stretch-and-folds after the first 2 hours makes the gluten underdeveloped. Do 3-4 sets of 30-second stretches and 30-second folds during the first 2 hours, then let it rest. Your sandwich loaves will have that satisfying chew without being dense.
- WEIGH YOUR FLOUR: I used to eyeball the all-purpose and bread flour mix, and my batches came out inconsistent. This recipe relies on precise hydration—use a kitchen scale for both flours. The bread flour’s protein content changes when you guess, and your oven spring will suffer. Trust the numbers, even if it feels fussy.
- SALT THE WATER: The recipe says to dissolve salt in the water before mixing, but I used to add it to the dough later. Big mistake—the salt needs time to fully integrate. If you add it dry or late, you’ll get uneven flavor and weaker gluten structure. Mix the salt into the water first, then proceed. Your bread will taste more balanced.
- SKIP THE OVERPROOFING: I once left my shaped loaves in the proofing basket for an extra hour, thinking more time meant better rise. Wrong—they collapsed flat in the oven. This recipe’s proofing time is tight; use the timer. If your kitchen’s warm (75°F+), reduce by 10-15 minutes. Overproofing kills the sandwich bread’s structure.
Common mistakes when making perfect results
Overproofed Dough
I’ve seen this happen more times than I can count—especially when the kitchen gets warm. If your dough rises too much before baking, it’ll collapse or develop a dense, gummy crumb. The fix? Chill the dough for 1-2 hours in the fridge before shaping to slow fermentation.
For a quick test, press your finger gently into the dough: if it springs back slowly (like Jell-O), it’s ready. If it springs back fast, it needs more time. 🌡️
Dense Crumb Texture
A dense, heavy crumb usually means the dough didn’t get enough gluten development or was overworked. To avoid this, use a mix of all-purpose and bread flour for structure, and don’t over-knead—this dough is meant to be sticky and loose.
If it happens anyway, try increasing the bread flour by ½ cup next time. Also, ensure your starter is active and bubbly—weak starter = weak rise.
Uneven Crust Browning
If one side of your loaf turns dark while the other stays pale, it’s likely due to uneven heat distribution. Rotate your pan halfway through baking, and use the foil trick properly—leave 1 inch of foil covering the top during most of the bake.
For extra insurance, bake on the middle rack where heat is most even. I’ve also found that a dark-colored loaf pan** (like my trusty Lodge) browns faster than lighter pans.
Sticky Dough Nightmare
This dough is intentionally sticky, but if it’s too unmanageable, you’re probably using too much water. The ratio in this recipe is precise—1.5 cups water for 5 cups flour—but humidity or flour type can throw it off.
If needed, add 1-2 tbsp extra flour while shaping, but don’t overdo it or you’ll kill the rise. Wet hands or a dough scraper help too—dust them with cornmeal or flour to keep things in check.
Foil Trick Fail
The foil trick is non-negotiable for that perfect crust, but if yours doesn’t work, you might’ve sealed it improperly. Make sure the foil is fully wrapped and sealed—no gaps! Also, don’t remove it too early.
I’ve learned the hard way that pulling the foil off before 30 minutes into baking can lead to a dry, crackly crust instead of the tender, crispy one you want. Patience is key here.
Soggy Sandwich Bread
If your sandwich bread gets soggy when toasted or used for sandwiches, it’s likely because the crumb didn’t set properly. Always let the bread cool completely in the pan for 10 minutes before transferring to a rack.
For extra insurance, store it wrapped in a bread bag or airtight container at room temp. To revive stale bread, pop it in a 200°F oven for 5-10 minutes—it’ll taste fresh again!

Frequently asked questions
Can I make this sourdough sandwich bread without a sourdough starter?
Yes! Use 1/4 teaspoon instant yeast instead of the starter for a similar texture, though the flavor won't be quite as tangy. For best results, let the dough ferment overnight in the fridge (8-12 hours) to develop some depth. The no-knead method still works perfectly—just skip the starter and add the yeast with the other dry ingredients.
Why does the foil trick matter for sandwich bread?
The foil creates a steam chamber during baking, which is essential for that signature sandwich bread texture. Without it, the crust becomes too hard while the interior stays dense. The steam also helps develop that open, airy crumb perfect for holding fillings without getting soggy. Think of it as a built-in Dutch oven effect!
How do I know when the bread is fully baked?
Look for three signs: the internal temperature should reach 190°F (use an instant-read thermometer), the crust should be deep golden brown, and it should sound hollow when tapped on the bottom. If unsure, bake 5 more minutes—it's better to slightly overbake than underbake sandwich bread.
Can I make this bread in a Dutch oven instead of using foil?
The Dutch oven method works beautifully for sandwich bread too. Shape the dough into a round boule, place it in the Dutch oven with a steam tray, then bake at 375°F for 35-40 minutes. The steam environment creates the same crisp crust and open crumb, though the shape will be round instead of a loaf.
How long does this bread stay fresh?
Wrapped in a bread bag or airtight container, this sourdough stays fresh at room temperature for 3-4 days. For longer storage, freeze the whole loaf (sliced or unsliced) for up to 3 months. To revive, thaw overnight at room temperature or warm in a 200°F oven for 10 minutes** before slicing.
