Ingredients for all purpose flour sourdough sandwich bread
Four cups flour plus a lively starter—this is your sandwich bread foundation.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 4 ½ cups | Bread flour substitute if unavailable |
| Active Sourdough Starter 🍞 | 1 cup | 100% hydration, bubbly and active |
| Granulated White Sugar 🍚 | ½ tsp | Fine grain preferred |
| Instant Yeast 🍞 | ¼ tsp | For added insurance |
| Large Eggs 🥚 | 1 whole | Room temperature |
| Unsalted Butter 🧈 | ½ cup | Cold, cubed for dough |
| Whole Milk 🥛 | 1 cup | Warmed to room temp |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Adjust to taste |
| Olive Oil 🫒 | 1 tbsp | For greasing bowl |
| Cornmeal 🌽 | ¼ cup | For dusting parchment |
| Water 💧 | ¾ cup | Room temperature |
The all-purpose flour is the secret weapon here—it delivers that perfect balance of structure and tenderness King Arthur or Bob's Red Mill are my go-tos for consistent results. Your starter needs to be peaking activity (bubbly, doubled in 4-6 hours)—this is non-negotiable for that signature tang. I always weigh mine at 100g hydration for reliable performance. The butter should be cold but not hard—think soft enough to press with your thumb but not melt instantly. Plugrá or Land O'Lakes work perfectly. Pro tip: if your kitchen runs warm, chill the butter for 10 minutes before adding to the dough.
No active starter? Feed 50g flour + 50g water every 12 hours for 24 hours to activate one. Running short on butter? Vegetable shortening at half the amount works in a pinch, though it won't add the same flavor. The milk can be any kind—whole, 2%, or even almond milk—just make sure it's room temperature. For the salt, Diamond Crystal measures differently than Morton—use the 1.5 tsp measurement for accurate seasoning. Need to make this gluten-free? Swap the flour for a 1:1 gluten-free blend but expect a denser crumb. The olive oil is just for greasing—any neutral oil will do, but don't skip it!
This dough is a 24-hour project—plan ahead! The starter can be prepped the night before, and the dough benefits from overnight cold proofing. Store your starter in the fridge between feedings if making it ahead. For the final loaf, wrap tightly in plastic and refrigerate for up to 5 days, or freeze for 3 months by wrapping in foil and plastic. Toasting revives stale bread beautifully—pop slices in the toaster for 30 seconds at 375°F for that fresh-baked crisp. The crust stays crisp for 2 hours out of the oven, so slice immediately if you can't wait!
Why You'll Love This Recipe
- No Fussy Starter Math: I swear by this recipe because it treats my sourdough starter like a friend—not a science experiment. Just toss in the active starter (that bubbly, happy one you’ve been feeding) with the all-purpose flour, a pinch of sugar, and a splash of water. No stressing over hydration percentages or exact timings. It’s the kind of bread that forgives my occasional "I’ll check it tomorrow" moments.
- Tangy-Sweet Crust: Between us, the crust on this bread is ridiculously good. The sugar caramelizes just enough to give it a subtle sweetness, while the sourdough starter adds that deep, tangy punch. It’s the kind of flavor that makes you pause mid-bite, even if you’re just slathering it with peanut butter.
- Lunchbox Legend: Honestly, this is my go-to for sandwiches—no matter the occasion. The soft, airy crumb holds up to grilled cheese, PB&J, or even a quick tuna melt. And because it’s made with all-purpose flour, it’s lighter than my usual whole-grain loaves, so it doesn’t turn into a soggy mess in a packed lunch.
- Budget-Friendly Staple: I make a batch every two weeks, and it lasts. The all-purpose flour keeps it affordable, and the yeast + sugar combo means it rises faster than my usual sourdough. Plus, the leftovers? Perfect for toast, croutons, or even breadcrumbs. It’s the kind of recipe that pays for itself in convenience.
Step-by-step instructions for all-purpose flour sourdough sandwich bread
Here's how to craft a loaf with that perfect balance of crispy crust and airy crumb—every time.
Combine Wet Ingredients for a Smooth Dough Base
In a stand mixer fitted with the dough hook attachment, combine the 1 cup active sourdough starter, 1 whole large egg, 1 cup whole milk, 0.5 cup unsalted butter (cold, cubed), 0.5 tsp granulated white sugar, 0.25 tsp instant yeast, and 1.5 tsp diamond crystal kosher salt. Mix on low speed for 2 minutes until the butter begins to emulsify and the mixture looks shaggy but cohesive.
This is where the magic begins—the cold butter creates pockets that will later give your bread that tender crumb. If the butter melts too quickly, chill the bowl for 5 minutes before proceeding. You're aiming for a thick, sticky batter that clings to the sides of the bowl when you lift the hook.
Gradually Incorporate the All-Purpose Flour
With the mixer running on low speed, slowly add the 4.5 cups all-purpose flour through the feed tube, beginning and ending with about 1 cup. Mix for an additional 5-7 minutes until the dough pulls away from the sides of the bowl and begins to form a smooth, elastic ball. The dough should be slightly tacky but not sticky enough to leave residue on your fingers.
If the dough feels too wet after mixing, add 1 tablespoon of flour at a time until it reaches the right consistency. Over-kneading develops gluten too much, which can make the bread dense. You'll know it's ready when the dough springs back slowly when poked with a finger—like a well-set Jello.
Bulk Ferment for Maximum Flavor Development
Transfer the dough to a lightly oiled bowl, cover it with a damp kitchen towel, and let it rest at room temperature for 1-2 hours. During this time, the dough will nearly double in size as the yeast and sourdough starter work their magic. Gently punch down the dough every 30 minutes to redistribute the gluten and prevent overproofing.
Here's the thing—this bulk fermentation is where the bread gets its depth of flavor. You'll notice bubbles forming on the surface and along the sides of the dough. When the dough has risen to about 75% of its original volume, it's ready for the next step. If your kitchen is warm, reduce fermentation time to 45-60 minutes to avoid overproofing.
Shape and Proof for the Perfect Crust
Lightly flour a clean surface and turn out the dough. Gently shape it into a 9x5-inch loaf pan by folding the edges toward the center and pressing down firmly. Dust the top with 0.25 cup cornmeal and cover loosely with plastic wrap. Let it proof at room temperature for 1-1.5 hours, or until the dough has risen 1-2 inches above the pan and looks slightly domed.
Don't skip this shaping step—it ensures an even rise and a uniform crumb structure. If you're in a hurry, you can proof the dough in the fridge overnight for even more flavor development. Just make sure to bake it the next day without letting it come to room temperature first.
Bake to Golden Perfection with Steam
Preheat your oven to 375°F and place a baking sheet on the lower rack. Pour 0.75 cup water into the baking sheet to create steam, which helps develop that beautiful crust. Bake the bread for 30-35 minutes until the top is deep golden brown and the internal temperature reaches 190-200°F.
Here's the secret to that crispy crust: As soon as you take the bread out of the oven, invert it onto a wire rack. The steam trapped inside will continue to develop that crackly exterior while the interior stays soft and pillowy. Let it cool for at least 1 hour before slicing—this resting time allows the gluten to relax and the crumb to set properly.
Pro Tips For Making All Purpose Flour Sourdough Sandwich Bread
- STRETCH THE DOUGH: Use the "windowpane test" at bulk fermentation—pull a small piece and stretch it thin. If it tears without ripping, it’s ready. Overstretching all-purpose flour dough is easier than with bread flour, so stop just before it feels too loose. (I learned this after one batch collapsed like a sad soufflé.)
- CHECK STARTER TEMP: Your starter should be between 75°F–80°F (24°C–27°C) when feeding it for this recipe. Cold starter slows fermentation, and warm starter can make the dough rise too fast, leading to dense bread. If your kitchen’s chilly, pop the jar near the oven with the light on—it’s a free, reliable heat source.
- WEIGH THE EGG: Crack that egg into a measuring cup first. All-purpose flour sourdough benefits from precise hydration, and a whole egg (or even a yolk) can throw off the dough’s structure. Aim for 50g per large egg—no guessing, no sad, gummy loaves.
- SKIP THE COLD PROOF: Let the shaped loaves proof at room temp (70°F–75°F) for 1–1.5 hours instead of refrigerating. Cold proofing works for artisanal bread, but sandwich bread needs a faster, more predictable rise. Just watch for the dough to spring back slowly when poked—it’s ready when it leaves a faint dent. (Yes, even if you’re impatient like me.)
Creative variations of all purpose flour sourdough sandwich bread
Herb-Infused Twist
Add 1 tbsp fresh rosemary or 1 tbsp fresh thyme to the dough during the final mix for an aromatic twist. I like using King Arthur's herb blend for convenience—just 1 tsp adds earthy depth.
For a Mediterranean flair, fold in 1 tbsp finely chopped Kalamata olives before shaping. These herbs infuse beautifully during fermentation, creating layers of flavor in every slice. 🌿
Whole Wheat Substitution
Replace 1.5 cups of all-purpose flour with 1.5 cups whole wheat flour for a nuttier, heartier loaf. I recommend Bob's Red Mill whole wheat flour for its consistent grind. To maintain a light texture, add 1 tbsp vital wheat gluten to the dry ingredients.
The dough will be slightly denser, so reduce the water by 1 tbsp if needed. This version pairs perfectly with hearty sandwich fillings like smoked turkey and avocado. 🌾
Cheesy Garlic Bread
For a decadent variation, fold in ½ cup shredded sharp cheddar and 2 cloves minced garlic during the final mix. I use Cabot cheddar for its melty texture. After shaping, sprinkle an additional ¼ cup shredded cheese on top before baking.
The cheese creates pockets of gooey goodness while the garlic adds a warm, savory note. This version is perfect for breakfast sandwiches or charcuterie boards. 🧀
Seeded Crust Boost
Create a textured crust by mixing 2 tbsp sesame seeds and 2 tbsp poppy seeds into the cornmeal dusting. For extra crunch, press 1 tbsp flaxseeds into the dough before shaping. These seeds add visual appeal and a delightful crunch with every bite.
I love using Penzeys Spices for their high-quality seeds. This variation works especially well with savory sandwiches like egg salad or smoked salmon. 🌰
Sweet Cinnamon Swirl
Transform your sandwich bread into a breakfast loaf by adding 1 tsp cinnamon and 2 tbsp brown sugar to the dough. After shaping, create a well in the center and fill with a mixture of ¼ cup softened butter, 2 tbsp brown sugar, and 1 tsp cinnamon.
Swirl with a knife before baking for a beautiful pattern. This version is perfect for French toast or cinnamon raisin sandwiches. 🍯
Savory Sun-Dried Tomato
Add ¼ cup finely chopped sun-dried tomatoes (oil-packed) to the dough for a Mediterranean-inspired twist. I like using Muir Glen sun-dried tomatoes for their rich flavor. For extra depth, add 1 tsp dried oregano to the dry ingredients.
These tomatoes add a tangy, umami note that pairs beautifully with grilled meats or fresh mozzarella. This variation is perfect for gourmet sandwiches and antipasto platters. 🍅

Frequently asked questions
Why does this recipe use all-purpose flour instead of bread flour?
All-purpose flour creates a lighter, more tender crumb perfect for sandwich bread while still developing enough structure for a crispy crust. Unlike bread flour, it doesn't overdevelop gluten, which can make the loaf too chewy. This version delivers that ideal balance of softness and chew—just right for toast or sandwiches!
Can I make this bread without an active sourdough starter?
Feed 50g flour + 50g water every 12 hours for 24 hours to create one. For faster results, use 1 extra teaspoon of instant yeast in the recipe. The dough will still develop that signature tang, though it may be slightly milder than with a mature starter.
How do I know when the dough is properly proofed?
Look for 75% volume increase and visible bubbles on the surface. When you gently press your finger into the dough, it should spring back slowly (like well-set Jello). Overproofing happens when it collapses or feels hollow—this means it's past its peak. For warm kitchens, proof for 45-60 minutes instead of 1-2 hours.
Why does my crust turn out too thick or too thin?
Thick crusts often mean the oven wasn't hot enough (375°F is critical) or the steam wasn't sufficient. Thin crusts usually indicate overproofing or insufficient baking time. For perfect crust: Use a steam tray, bake until internal temp reaches 190-200°F, and avoid opening the oven door during baking.
How long can I store this bread, and how do I revive stale slices?
Wrap tightly in plastic and refrigerate for 5 days or freeze for 3 months. To revive: Toast slices at 375°F for 30 seconds or warm in a 350°F oven for 5-10 minutes wrapped in foil. For extra crispiness, brush with melted butter before toasting. The butter adds moisture and restores that fresh-baked texture!
