Side Dishes
This whole wheat sourdough bread recipe delivers restaurant-quality crusty crunch with deep nutty flavor—perfect for feeding 50. The secret lies in balancing whole wheat’s density with proper hydration and extended fermentation, creating a loaf that’s both hearty and light. I’ve scaled this recipe to yield 10 large loaves or 50 rolls, designed for bakeries or large gatherings where texture and flavor matter most.
The process starts with a robust whole wheat starter that develops complex flavors over 24 hours, then transitions to bulk fermentation where gluten develops fully. Using a stand mixer for initial kneading saves time while maintaining structure, and cold proofing overnight ensures predictable rise.
Scoring the loaves before baking at 450°F creates that coveted crusty exterior while keeping the crumb tender.
By the time it emerges from the oven, you’ll have bread with a crispy, caramelized crust and an open, airy crumb that’s perfect for sandwiches, toast, or serving with soups.
The whole wheat adds subtle earthiness without overpowering, making this versatile enough for everyday meals while impressive enough for special occasions.
For best results, bake in Dutch ovens to trap steam, and let the bread cool completely before slicing—this ensures clean cuts and maximum flavor development. The recipe accommodates modern tools while honoring traditional techniques, delivering professional-quality bread without the fuss.

The King Arthur Bread Flour is non-negotiable here—it handles the whole wheat's density better than most. Bob's Red Mill whole wheat flour works too, but avoid pre-milled blends with additives. For the starter, King Arthur's sourdough mix is a lifesaver if you're short on time, but nothing beats a 24-hour fed starter. The Dutch ovens? Lodge makes the best—no substitutes for their cast iron heat retention. I always double-check my yeast is instant; active dry needs extra time and won't develop the same structure.
No Dutch ovens? Banneton baskets with parchment-lined pans work for rolls, but you'll lose that signature crust. Running short on whole wheat flour? Substitute 2 cups of all-purpose for every 1 cup missing, but expect a slightly denser crumb. The honey can be swapped for maple syrup or agave—just adjust to 1.5 tbsp if using. For large batches, King Arthur's bulk flour at WinCo Foods is cheaper than grocery stores. And trust me on the olive oil—California avocado oil works too, but olive adds that authentic sourdough depth.
This dough needs 24 hours of cold proofing—set a timer! Store shaped loaves in parchment-lined boxes at room temp for 2 days, or freeze wrapped for 3 months. The rolls? Freeze unbaked on parchment for 2 weeks—bake straight from frozen. Pro tip: Score loaves with a razor while dough is still cold—it stays crisp longer. And for that crispy crust, bake at 450°F with steam for the first 15 minutes, then broil 2 minutes at the end.

Step-by-step instructions for 50 whole wheat sourdough bread
Here's how to transform your active starter into 50 perfectly crusty, nutty loaves with an open crumb and satisfying chew.
Mix the Autolyse for Optimal Gluten Development
In a stand mixer fitted with the dough hook attachment, combine the 6 cups whole wheat flour and 6 cups water. Mix on low speed for 2 minutes until just combined—you should see a shaggy, sticky mass with no dry spots. This initial mix, called an autolyse, allows the flour to fully hydrate and begin gluten development before we add the remaining ingredients.
Cover the bowl with a damp towel and let rest for 30 minutes. During this time, the dough will become more elastic and easier to handle. I always check the dough after 20 minutes—it should look smoother and feel slightly less sticky. This resting period is crucial for developing the gluten structure that will give your bread its satisfying chew.
Incorporate Starter, Yeast, and Wet Ingredients
After the autolyse, add the 4 cups active whole wheat sourdough starter, 0.75 cup extra-virgin olive oil, 2 tbsp honey, 1 tbsp granulated sugar, 1 tbsp instant yeast, and 2 tbsp diamond crystal kosher salt to the dough. Mix on medium speed for 5 minutes until the dough comes together and begins to pull away from the sides of the bowl.
The dough will be sticky at this stage—this is normal with whole wheat flour. To help with handling, add the 2 cups unbleached all-purpose flour gradually during the final minute of mixing. The all-purpose flour acts as a structural support, helping to balance the heaviness of the whole wheat. The dough should be smooth, elastic, and slightly tacky but not wet.
Bulk Ferment for Maximum Flavor Development
Transfer the dough to a lightly oiled bowl, cover with a damp towel, and let ferment at room temperature for 4 to 6 hours. The dough should roughly double in size during this time. I check it every hour after the 3-hour mark—look for about 50% increase in volume and a noticeable jiggle when you shake the bowl gently.
During the bulk ferment, the yeast will consume the sugars, producing carbon dioxide that creates air pockets and develops flavor. The whole wheat flour will contribute its characteristic nutty depth, while the olive oil adds elasticity. If your kitchen is cool (below 70°F), you may need to extend the ferment time. The dough should pass the "poke test"—when you press your finger gently into the dough, it should spring back slowly, leaving a slight indentation.
Shape and Proof the Dough
Turn the dough out onto a lightly floured surface and divide it into 10 equal portions, each weighing about 1 pound. Shape each portion into a round boule by pulling the sides toward the center and tucking them under. Place each shaped boule into a generously dusted Dutch oven or banneton basket, seam-side up.
Cover the baskets with damp towels and let proof at room temperature for 1 to 2 hours, or until the dough has risen about 25-30% and feels springy to the touch. The proofing time can vary based on your kitchen's temperature and humidity. For best results, proof the dough until it reaches about 75°F internal temperature. This final rise develops the open crumb structure that makes sourdough bread so satisfying.
Bake for Crusty Crunch and Nutty Depth
Preheat your oven to 450°F with a Dutch oven or baking stone inside for at least 45 minutes. When ready to bake, transfer the proofed loaves directly from the baskets to the hot Dutch oven or baking stone. Bake for 30 minutes with the lid on, then remove the lid and bake for an additional 20 to 25 minutes, until the bread reaches an internal temperature of 205°F and the crust is deep golden brown.
For that classic sourdough crust, I like to spray the loaves with water just before removing the lid. The steam creates a beautiful oven spring and enhances the crust's crispiness. Let the bread cool on a wire rack for at least 1 hour before slicing—this allows the crumb to set and prevents a gummy texture. The result should be a loaf with a crisp, crackly crust and an open, airy crumb that's both tender and chewy, with a deep, nutty flavor from the whole wheat flour.
Pro Tips For Making 50 Whole Wheat Sourdough Bread
- STIR THE DOUGH LONG ENOUGH: Whole wheat dough is stubborn—it hides pockets of dry flour that need aggressive mixing to fully hydrate. After adding the King Arthur Bread Flour, stir with a wooden spoon or dough whisk for at least 10 minutes before turning it loose. I used to rush this, and my bread always came out dense. Trust me, your kneading will thank you later.
- WEIGH YOUR WHOLE WHEAT FLOUR: King Arthur Bread Flour is light and fluffy, but whole wheat flour packs like sand. Use a kitchen scale for both—don’t eyeball it. A 10-gram difference in the whole wheat can throw off hydration and make your dough either too sticky or too stiff. (Yes, even if you’re impatient like me.)
- LET THE STARTER RISE TO PEAK: Your active whole wheat sourdough starter should bubble vigorously and double in size before using it. If it’s sluggish or just floating, give it another 30–60 minutes—whole wheat starters often need more time than white flour starters. I learned this the hard way when my first batch turned out flat and sad.
- SKIP THE INSTANT YEAST IF STARTER’S STRONG: This recipe includes instant yeast, but if your whole wheat starter is robust (active, bubbly, and smells tangy), cut it in half or omit it entirely. The yeast can overpower the sourdough flavor, and your bread might rise too fast, leading to a gummy crumb. (Your future self will thank you for this.)
Creative variations of 50 whole wheat sourdough bread
Herb-Infused Twist
Add 2 tbsp fresh rosemary and 1 tbsp fresh thyme to the dough during the final mixing stage for an aromatic twist. The herbs pair beautifully with whole wheat’s nutty notes, creating a fragrant loaf perfect for holiday gatherings.
I like to finely chop the herbs and mix them with the olive oil before adding to the dough—this distributes them evenly. 🌿
Seeded Crunch
For added texture, fold in 1 cup pumpkin seeds or sesame seeds during the bulk fermentation. The seeds add a satisfying crunch and visual appeal, especially when baked into rolls or small loaves.
Toast the seeds in a dry pan for 2-3 minutes before mixing to enhance their flavor. Store-bought seed blends work too, but homemade combinations taste fresher.
Sweet Swirl Version
Transform this into a sweet loaf by replacing 1 cup whole wheat flour with 1 cup white whole wheat flour and adding ½ cup honey plus 1 tsp cinnamon to the dough. Shape into boules and bake as directed.
The result is a lightly sweet bread perfect for French toast or dessert sandwiches. For extra indulgence, add ½ cup dried cranberries during the final mix.
Savory Garlic & Olive
Boost umami by mixing 3 minced garlic cloves and 2 tbsp finely chopped Kalamata olives into the dough during the autolyse stage. The garlic infuses deeply during fermentation, while the olives add bursts of briny flavor.
This variation works exceptionally well when sliced for sandwiches or served with olive oil and balsamic vinegar. 🧄
Whole Grain Blend
Experiment with alternative whole grains by replacing 2 cups whole wheat flour with 1 cup spelt flour> and 1 cup rye flour>. The spelt adds a mild sweetness while the rye deepens the flavor profile.
For a lighter texture, use King Arthur's multigrain flour> instead—it blends seamlessly with the whole wheat. Each grain brings unique characteristics, so taste-test small batches before committing to the full recipe.
Mini Rolls Adaptation
For 50 individual rolls, divide the dough into 50 equal portions> (about 3.5 oz each>) and shape into balls. Place on a parchment-lined baking sheet, cover, and proof for 1.5-2 hours.
Bake at 425°F> for 15-18 minutes>, spraying with water after 10 minutes> for steam. These bite-sized rolls are perfect for parties or as a side to soups.
Freeze unbaked rolls on parchment for up to 2 weeks>—bake straight from frozen, adding 5 minutes> to the baking time.
Nutrition facts
Frequently asked questions
Why does this recipe use both whole wheat and bread flour?
Whole wheat flour adds nutty depth and fiber, but its dense structure can make bread heavy. The King Arthur Bread Flour provides high protein for better gluten development, creating that perfect open crumb. This blend balances nutrition with texture—you get hearty flavor without sacrificing a light, airy interior.
How do I know when my whole wheat starter is ready?
Your starter should be bubbly, doubled in size, and smell slightly sweet or tangy after 24 hours of feeding. It should float in water like a cork—this confirms active fermentation. If it's sluggish, feed it again with equal parts flour and water and wait another 8-12 hours. A strong starter is the foundation of great sourdough!
Can I make this recipe without a stand mixer?
The dough is sticky but manageable by hand. Use a dough scraper to fold and stretch the dough during bulk fermentation. For shaping, wet your hands and work quickly—whole wheat dough sticks less than all-purpose. The autolyse step (resting before adding starter) makes the dough easier to handle. Just expect to work a little harder!
What if my dough doesn't rise enough?
Cool temperatures or weak starter are usually the culprits. Try these fixes: Move your dough to a warmer spot (like near the oven with the light on), extend bulk fermentation by 1-2 hours, or feed your starter more frequently. If using instant yeast, check the expiration date—old yeast loses potency. Patience is key with whole wheat!
How should I store this bread for large gatherings?
For short-term storage, keep loaves in parchment-lined boxes at room temperature for up to 2 days. For longer storage, freeze wrapped loaves for 3 months or freeze unbaked rolls for 2 weeks. Thaw at room temperature or reheat baked rolls in a 350°F oven for 5-10 minutes to restore freshness.
