Ingredients for 75 hydration sourdough bread
Your well-fed starter and these precise ingredients create a loaf with an open crumb and crisp crust.
| Ingredient | Amount | Notes |
|---|---|---|
| Active Sourdough Starter 🍞 | ½ cup | 100% hydration, bubbly and active |
| All-Purpose Flour 🌾 | 4 cups | King Arthur or Bread Flour preferred |
| Whole Wheat Flour 🌾 | ½ cup | For added texture and nutrition |
| Granulated Sugar 🍚 | ⅛ cup | Feeds the starter and enhances browning |
| Unsalted Butter 🧈 | ¼ cup | Cold, cubed for flavor and richness |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | Fine grain for even distribution |
| Water 💧 | 1 ½ cups | Room temperature, filtered preferred |
| Olive Oil 🫒 | 1 tbsp | For dough handling and scoring |
| Cornmeal 🌽 | ¼ cup | For dusting baking surface |
| Ice Cubes ❄️ | 1 piece | For steam in Dutch oven |
The starter is your secret weapon—it needs to be 100% hydration and actively bubbling before mixing. King Arthur or Bread Flour delivers the best gluten structure for that open crumb, but all-purpose works in a pinch. For the whole wheat, Bob's Red Mill is my go-to—it adds subtle nuttiness without overpowering. The sugar feeds your starter while caramelizing beautifully in the crust. Don't skip it. Water temperature matters: too cold and the dough won't activate properly; too warm and fermentation speeds up uncontrollably. Room temperature (around 70°F) is ideal. If your kitchen runs hot, chill the water slightly.
No sourdough starter? Instant yeast at half the amount of your starter (so 0.25 tsp) gets you close, though the flavor won't be quite the same. Substituting all whole wheat flour? Reduce by 10% to avoid density. For the butter, European-style unsalted works best—it has higher fat content for that rich flavor. Running short on time? Cold-proof the dough overnight instead of doing the full 4-hour bulk ferment. The salt is non-negotiable—Diamond Crystal dissolves evenly, unlike table salt which can create pockets of saltiness. And that olive oil? Use something fruity and peppery—none of that bland supermarket stuff.
Your starter should keep in the fridge indefinitely, but use it within 1 week once fed. The dry ingredients (flours, sugar, salt) stay fresh for 6 months in airtight containers. Store the butter in the freezer to preserve freshness. The dough can be cold-proofed for up to 48 hours in the fridge—perfect for baking overnight. Once baked, cool the loaf completely on a wire rack (at least 2 hours) to prevent sogginess. Slice with a serrated knife for clean cuts, and store wrapped at room temperature for 3 days or freeze for 3 months. The crust gets crunchier as it sits, so reheat slices in a dry pan for freshness.

Step-by-step instructions for 75% hydration sourdough bread
Here's how to transform simple ingredients into a loaf with an open crumb and crispy crust.
Mix the Dough with Wet and Dry Components
In a large mixing bowl, combine the 0.5 cup active sourdough starter, 1.5 cups water, and 0.125 cup granulated sugar. Let this sit for 10 minutes while you prepare the dry ingredients. This gives the starter time to activate fully in the liquid.
In a separate bowl, whisk together the 4 cups all-purpose flour, 0.5 cup whole wheat flour, and 1.5 tsp diamond crystal kosher salt. Add the cold, cubed 0.25 cup unsalted butter to the dry ingredients and use your fingers to work it into the flour until it resembles coarse crumbs. This butter will create pockets of richness throughout the bread.
Combine and Develop the Dough
Pour the wet starter mixture into the dry ingredients and mix with a wooden spoon until just combined. The dough will be shaggy and sticky at this point - that's normal with 75% hydration. Add the 1 tbsp olive oil and mix until fully incorporated. Wet your hands and work the dough for 2-3 minutes until it comes together but remains slightly tacky.
Cover the bowl with plastic wrap and let it rest for 30 minutes at room temperature. This rest period allows the flour to fully hydrate and the gluten to begin developing. You'll notice the dough becomes slightly smoother and more cohesive during this time.
Shape and Prepare for Final Rise
Lightly dust a clean work surface with 0.25 cup cornmeal. Turn the dough out onto the surface and gently shape it into a loose round by folding the edges toward the center. Don't overwork it - just enough to create surface tension. Place the shaped dough seam-side up in a lightly oiled bowl.
Cover the bowl and let it rise at room temperature for 4-6 hours, or until it has nearly doubled in size. You'll know it's ready when the dough springs back slowly when poked gently with a finger. The whole wheat flour will give it a slightly denser texture compared to 100% all-purpose flour doughs, but it will still develop good oven spring.
Preheat and Prepare for Baking
Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. This creates the perfect steam environment for a crispy crust and open crumb. While the oven heats, place the 1 piece ice cube in the bottom of your Dutch oven - this will create additional steam during baking.
Once the oven is fully preheated, carefully transfer the dough to the hot Dutch oven. If needed, use a well-floured surface to help slide the dough in. Sprinkle additional cornmeal on top for extra crunch. Bake covered for 30 minutes, then remove the lid and bake for another 15-20 minutes until the bread is deep golden brown.
Cool and Enjoy
Remove the bread from the Dutch oven and let it cool on a wire rack for at least 1 hour before slicing. The internal temperature should drop to 100°F before cutting to prevent a gummy crumb. The butter and sugar will give this loaf a slightly sweet, rich flavor with a crispy crust that shatters when broken.
For best results, store wrapped in a clean kitchen towel at room temperature for up to 3 days. The whole wheat flour adds subtle nuttiness that pairs beautifully with the airy crumb created by the high hydration. This bread freezes well too - slice before freezing for perfect toast every time.
Pro Tips For Making 75 Hydration Sourdough Bread
- STRETCH AND FOLD: Mix the dough by hand until it’s shaggy, then let it rest 20 minutes before the first fold—this saves arm strength and prevents overworking. I used to skip this, and my dough always felt dense afterward.
- WEIGH THE WHOLE WHEAT: Use a kitchen scale for the whole wheat flour; scooping leads to inconsistent hydration. Whole wheat absorbs water differently than all-purpose, and you’ll avoid a gummy loaf or one that’s too dry.
- AVOID OVERPROOFING: Check the dough’s readiness by the poke test twice—once when it looks close, then again 30 minutes later. I learned this the hard way when my loaves collapsed because I waited too long.
- SKIP THE SUGAR IN DOUGH: Add the granulated sugar after shaping, not during autolyse—it feeds yeast too early and can make the dough rise unevenly. Save it for the final mix to control fermentation better.
Common mistakes when making this recipe
Over-Mixing Dough
I’ve seen beginners overwork this sticky dough, thinking more handling equals better gluten development. But with 75% hydration, the dough is delicate—overmixing can break down gluten strands, leading to a dense, gummy crumb.
Instead, focus on gentle stretching and folding during bulk fermentation. After the initial mix, just let the dough rest and develop naturally. 💪
Ignoring Starter Readiness
A sluggish starter is the #1 reason for weak oven spring. Your starter should be bubbly, domed, and pass the float test (drop a spoonful in water—it should float).
If it’s flat or smells harsh, feed it 1:1:1 (flour:water:starter) 4–6 hours before mixing. I’ve ruined loaves by skipping this step—don’t make the same mistake!
Skipping the Autolyse
The 30-minute rest after mixing isn’t optional—it’s where gluten starts forming and the flour fully hydrates. Without it, your dough will fight you during shaping, and the crumb will lack that signature open texture. Think of it as a gluten-building power nap for your dough. 🌱
Underproofing or Overproofing
Proofing is an art: underproofed dough collapses in the oven, while overproofed dough loses structure. Test readiness by gently pressing a finger into the dough—it should spring back slowly (not instantly).
For this recipe, 4–6 hours at room temp is ideal. If your kitchen’s warm, reduce time; if it’s cool, extend it. A window thermometer helps!
Poor Scoring Technique
Scoring isn’t just decoration—it directs oven spring. Use a sharp lame or razor to cut ½-inch deep at a 45-degree angle. Avoid pressing too hard (you’ll tear the dough) or cutting too shallow (it won’t guide the rise).
I like to score 3–4 diagonal lines on the top. Pro tip: Dip the blade in water first for cleaner cuts. ✨
Baking Without Steam
That ice cube in the Dutch oven isn’t optional—it creates steam for a crisp crust and open crumb. Without it, your bread will bake hard and dense. Preheat the Dutch oven covered for 45 minutes to trap steam.
If you don’t have a Dutch oven, use a baking stone and spray the oven walls with water when loading the dough. 🔥

Frequently asked questions
Why use 75% hydration instead of 100%?
The 75% hydration creates a dough that's sticky but manageable, producing a lighter crumb than higher hydration ratios. This ratio balances ease of handling with an open, airy texture. The whole wheat flour also helps absorb moisture better, preventing a gummy result. For beginners, this is more forgiving than ultra-high hydration doughs.
Can I substitute the whole wheat flour?
Yes, but expect differences in texture and flavor. Replace the 0.5 cup whole wheat with all-purpose flour for a lighter crumb, or use spelt flour for a nuttier taste. If substituting, reduce by 10% to avoid density. The whole wheat adds subtle nutrition and a slightly denser crumb that pairs perfectly with the airy structure.
How do I know when the dough is properly proofed?
Press your finger gently into the dough—it should spring back slowly (not instantly). The dough should also nearly double in size, with visible bubbles on the surface. For this recipe, 4-6 hours at room temperature is ideal. If your kitchen is warm, reduce time; if cool, extend it. A window thermometer helps track your environment.
What if I don't have a Dutch oven?
Use a baking stone or steel pan instead. Preheat it in the oven for 45 minutes with the oven rack on the bottom position. When loading the dough, spray the oven walls with water to create steam. For extra crust development, place an ice cube in the bottom of the pan. The bread won't be as crispy, but it'll still have a good crumb.
How long should I let the bread cool before slicing?
Wait at least 1 hour before slicing to prevent a gummy texture. The internal temperature should drop to 100°F. Cooling on a wire rack helps maintain crispness. If you're impatient, slice after 30 minutes but expect slightly denser slices. The butter and sugar in this recipe make the bread more forgiving than plain sourdough.
