Ingredients for 50 50 whole wheat sourdough bread
Wild yeast and whole grains create this nutty, artisanal loaf—perfect for sandwiches or toast.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| All-Purpose Flour 🌾 | 1 ½ cups | For structure and lightness |
| Whole Wheat Flour 🌾 | 1 ½ cups | Unbleached, stone-ground preferred |
| Granulated Sugar 🍚 | ⅛ cup | Feeds the yeast |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for fat content |
| Instant Yeast 🍞 | ½ tsp | Boosts fermentation |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain preferred |
| Water 💧 | 1 ½ cups | Room temperature, 70°F |
| Honey 🍯 | 1 tbsp | For sweetness and moisture |
| Olive Oil 🫒 | 1 tbsp | For dough handling |
| Cornmeal 🌽 | ¼ cup | For dusting parchment |
| Semolina Flour 🌾 | ⅛ cup | For crust texture |
The whole wheat flour is the secret to that nutty depth, but it’s a finicky ingredient. King Arthur or Bob’s Red Mill are my go-tos—they’re consistently high-quality. Look for unbleached varieties to avoid grayish hues in your dough. The sourdough starter needs to be active and bubbly; if it’s sluggish, feed it 12 hours before baking. For the all-purpose flour, Gold Medal or King Arthur work beautifully—they’re reliable for structure. The honey adds subtle sweetness and helps with hydration, so don’t skip it even if your dough feels dry.
No whole wheat flour? Spelt flour or rye flour can substitute at a 1:1 ratio, but expect a denser crumb. Short on instant yeast? Active dry yeast works too—just dissolve it in warm water first. The butter is non-negotiable for that rich, artisanal flavor, but if you’re dairy-free, vegan butter or coconut oil will work. The olive oil is just for handling—you could use any neutral oil, but it adds a touch of Mediterranean flair. For the sugar, maple syrup or agave can replace honey, but reduce by 10% since they’re sweeter. And if you’re using a mix of flours, sift them together to avoid lumps—trust me, it’s worth the extra minute.
This dough is a beast—it needs time to develop flavor. After the initial bulk fermentation, refrigerate it overnight for deeper flavor and easier handling. The starter keeps in the fridge for up to 2 weeks, but feed it weekly. For the finished loaf, store it wrapped in a clean kitchen towel at room temperature for 2-3 days—it’ll stay fresh longer than plastic. Freeze slices for up to 3 months if you’re prepping ahead. And if you’re making multiple loaves? Double the recipe—it’s worth the effort.

Step-by-step instructions for 50/50 whole wheat sourdough bread
Here's how to craft artisanal sourdough with wild yeast character and nutty depth—every step matters.
Mix the Fermented Dough Base
In a large mixing bowl, combine the 0.5 cup active sourdough starter, 1.5 cups all-purpose flour, 1.5 cups whole wheat flour, and 1.5 cups water at 70°F. Stir vigorously for 2 minutes until fully incorporated and smooth. The dough should be slightly sticky but manageable—this indicates proper hydration for a tender crumb.
Add the 0.125 cup granulated sugar, 0.5 tsp instant yeast, and 1 tbsp honey, mixing until dissolved. The sugar and honey feed the yeast while balancing the earthy whole wheat flavor. Let this mixture sit at room temperature for 30 minutes—you'll see bubbles forming as fermentation begins. This initial fermentation develops flavor and lightens the dough structure.
Incorporate Fat and Salt for Structure
Cut the 0.25 cup cold unsalted butter into small cubes and add to the fermented mixture. Use your hands or a dough scraper to work the butter into the dough until fully incorporated—this creates pockets of fat that contribute to a tender crumb and rich flavor. The butter should be cold enough to resist melting but soft enough to distribute evenly.
Add the 1.5 tsp diamond crystal kosher salt and 1 tbsp olive oil, kneading gently by hand for 5 minutes until the dough comes together. The olive oil improves elasticity while preventing the whole wheat from absorbing too much moisture. The dough should be smooth but slightly tacky—this is ideal for our 50/50 blend. If it feels too dry, add 1 teaspoon water at a time until just combined.
Bulk Ferment for Flavor Development
Transfer the dough to a lightly oiled bowl, cover with a damp kitchen towel, and let ferment at 75°F for 4-6 hours. During this time, the dough should roughly double in size and develop a jiggly, airy texture. I like to perform stretch-and-folds every 90 minutes—wet my hands, grab one side of the dough, stretch it upward, and fold it over itself. This builds gluten structure while preventing the whole wheat from making the dough too dense.
Look for these signs of proper fermentation: the dough springs back slowly when poked, bubbles form on the surface, and a pleasant tangy aroma develops. If the dough rises too quickly (within 3 hours), it's overproofed—reduce fermentation time next batch. The whole wheat flour adds density, so we need extra time for proper gluten development.
Shape and Final Proof
Lightly dust a work surface with 0.125 cup semolina flour and turn out the dough. Gently shape into a round loaf by pulling the edges toward the center and tucking them underneath. The semolina creates a barrier that prevents sticking while adding a subtle nutty flavor to the crust. Place the shaped dough seam-side up in a greased pullman pan or round baking dish.
Cover loosely and let proof at 75°F for 1-2 hours until the dough has risen 50-75% above the pan's rim. The surface should look slightly domed with visible bubbles. For a more rustic look, you can shape into a boule instead—just dust with semolina and let proof on a floured baking sheet. The whole wheat flour requires careful handling during shaping to prevent tearing.
Bake for Crisp Crust and Open Crumb
Preheat your oven to 375°F with a Dutch oven inside for 45 minutes. This creates steam that develops an oven spring and crisp crust. Carefully transfer the dough (with pan) into the hot Dutch oven, cover, and bake for 30 minutes. Then remove the lid and bake for another 15-20 minutes until the crust is deep golden brown.
Check doneness by tapping the bottom—it should sound hollow. The internal temperature should reach 190-200°F. Immediately transfer to a wire rack and let cool for at least 1 hour before slicing. The whole wheat flour makes this bread dense when hot, but it develops proper texture as it cools. For extra crunch, brush the warm loaf with melted butter and sprinkle with flaky salt.
Pro Tips For Making 50 50 Whole Wheat Sourdough Bread
- Hydrate Whole Wheat First: Mix the whole wheat flour with water before adding it to the dough—this prevents clumping and makes the gluten relax properly. I learned this the hard way when my first batch turned into a dense brick because the whole wheat absorbed unevenly.
- Skip the Over-Kneading: Whole wheat dough resists overworking, so stop once the gluten is just developed—it should feel smooth but still slightly tacky. After burning three batches, I finally figured out that forcing it leads to a gummy, heavy crumb.
- Use Cold Butter: Cut the unsalted butter into small cubes and refrigerate them until the dough is ready to shape—this keeps the layers distinct and prevents the bread from turning greasy. Sounds weird, but it works: the butter stays in neat pockets instead of melting into the dough.
- Proof at Room Temp: Let the dough rise in a warm spot (75–80°F) for no more than 4–5 hours—whole wheat ferments faster than all-purpose, and overproofing kills the structure. I was skeptical until I tried it: the bread stayed light, not dense, even with the extra fiber.
Troubleshooting great 50 50 whole wheat sourdough bread
Dough Too Sticky?
Whole wheat flour absorbs moisture differently than all-purpose, making the dough extra sticky. If it feels unmanageable, add 1 tablespoon semolina flour at a time while kneading—this absorbs excess moisture without altering flavor.
I also recommend using a dough scraper to minimize sticking during handling. If the dough still clings, wet your hands slightly instead of flouring them. 💫
Fermentation Issues
If your dough rises too slowly (6+ hours), your starter may be weak or the room too cold. Feed your starter 12 hours before baking with equal parts flour and water by weight.
For cold environments, place the dough near a warm spot (like the oven with the light on) to maintain 75°F. Overproofed dough? It’ll look flat and smell overly tangy—reduce fermentation time by 1 hour next batch.
Dense Crumb Texture
Whole wheat flour naturally creates denser bread, but you can lighten the crumb by extending bulk fermentation to 6-8 hours and performing stretch-and-folds every 90 minutes. Avoid overmixing—the dough should be slightly tacky, not smooth.
For extra lift, add 1 extra tablespoon instant yeast if your kitchen is below 70°F. The key is patience: whole wheat needs more time to develop gluten.
Blotchy Crust
A blotchy crust usually means uneven heat distribution. Ensure your Dutch oven is preheated for 45 minutes before adding the dough. For a more even crust, sprinkle ice cubes on the dough before baking—this creates steam for a crisp, even browning.
If using a pullman pan, rotate it halfway through baking. A baking stone can also help distribute heat more evenly.
Starter Not Active?
A sluggish starter is the most common issue. Feed it 1:1:1 ratio (flour:water:starter by weight) and wait 4-6 hours for bubbles to form. If it still doesn’t rise, discard half and feed again. For a quick fix, add ¼ tsp extra instant yeast to the dough.
I keep my starter in a glass jar in the fridge—feed it weekly to maintain strength. Always use room-temperature starter for baking.
Bread Collapses After Baking
This happens when the dough loses gas too quickly. Ensure your oven is fully preheated and the Dutch oven is hot before adding the dough. For extra support, place a baking sheet under the Dutch oven to catch any spills.
If using a pullman pan, don’t overfill it—leave 1 inch headspace for proper expansion. The whole wheat flour makes the dough heavier, so monitor closely during the final 15 minutes of baking.

Frequently asked questions
Why does my whole wheat sourdough dough feel so sticky?
Whole wheat flour absorbs more moisture than all-purpose flour, creating a stickier dough. Use semolina flour (not all-purpose) to dust your surface—it absorbs excess moisture without altering flavor. Wet your hands slightly instead of flouring them, and work quickly to minimize sticking. A dough scraper is your best friend here!
Can I replace the whole wheat flour with white whole wheat?
White whole wheat flour works beautifully in this recipe—it has a lighter color and slightly sweeter taste while maintaining all the fiber benefits. Use a 1:1 substitution, but expect a slightly denser crumb. The flavor will be milder but still nutty, with a cleaner appearance for sandwiches.
How do I know when my sourdough starter is ready?
Your starter should be bubbly, doubled in size, and have a slightly tangy aroma within 4-6 hours after feeding. If it’s sluggish, feed it again (equal parts flour and water by weight) and wait another 2-4 hours. For baking, always use room-temperature starter—cold starter slows fermentation.
What if my bread turns out too dense?
Whole wheat naturally creates denser bread, but you can improve texture by extending bulk fermentation to 6-8 hours and doing stretch-and-folds every 90 minutes. Avoid overmixing—your dough should be slightly tacky, not smooth. For extra lift, add 1 extra tablespoon instant yeast if your kitchen is below 70°F.
Can I make this recipe without a Dutch oven?
Yes! Use a heavy ovenproof pot with a lid, or bake on a baking sheet with a metal bowl inverted over the dough to create steam. For best results, preheat the pot for 30 minutes before adding the dough. The crust won’t be as crisp, but the crumb will still be excellent with proper fermentation.
