75% Hydration Sourdough Bread Recipe: Crusty Open Crumb With Minimal Handling

A 75% hydration sourdough bread recipe delivers restaurant-quality crusty open crumb with minimal handling—no expensive equipment or complicated techniques required. The key lies in precise hydration control and strategic fermentation timing, which transform simple flour and water into artisanal bread with an open, airy crumb and crisp golden crust.

This approach balances professional results with home-baker accessibility, making it perfect for those who want authentic sourdough without the guesswork.

The beauty of this method is its foolproof structure: a well-maintained starter, careful mixing ratios, and controlled fermentation all work together to create a loaf that bakes up with dramatic oven spring and a satisfying crunch.

Unlike higher hydration doughs that demand constant attention, this recipe maintains manageable texture while delivering maximum flavor development. The result? A loaf that rivals bakery bread but stays within reach of any kitchen.

What sets this recipe apart is the crusty exterior and open crumb—hallmarks of traditional sourdough—achieved through precise shaping techniques and baking at high heat. The dough's slightly sticky nature (75% hydration) ensures maximum flavor extraction during fermentation while remaining workable.

With just a few key adjustments—like proper scoring and steam generation—you'll transform this dough into a loaf that looks like it came from a professional bakery.

Whether you're a first-time sourdough baker or looking to refine your technique, this recipe builds confidence through clear instructions and predictable results. The minimal handling approach means less stress and more time enjoying the process. Let's get started on creating your perfect loaf.

Ingredients for 75 hydration sourdough bread

Precise hydration and strategic ingredients create restaurant-quality sourdough with minimal handling effort.

The flour blend is critical for achieving that signature open crumb. King Arthur or Caputo bread flour delivers superior gluten structure, while unbleached all-purpose flour adds manageable elasticity. For the starter, maintain a 100% hydration culture with regular feedings—it should pass the float test (dropped in water, it floats) before use. Bulk bins at Whole Foods or specialty stores offer the freshest flour options, but avoid pre-sifted varieties as they lose structure. The vital wheat gluten acts like a secret weapon, boosting oven spring without altering flavor.

No bread flour? Add 1 extra tbsp of vital wheat gluten to all-purpose flour for comparable results. Short on olive oil? Avocado oil works equally well—just avoid anything with strong flavors like sesame. The ice water serves two purposes: it strengthens gluten development and prevents overproofing during bulk fermentation. For scoring, a lamé or sharp razor creates clean cuts; a dull blade will smash rather than slice. The dough's slightly sticky nature (75% hydration) is intentional—this ensures maximum flavor extraction while remaining workable.

Store your starter in a glass jar with a loose lid in the fridge, feeding weekly with equal parts flour and water. The dough itself keeps for 24 hours in the fridge before shaping—ideal for overnight proofing. After baking, let the loaf cool completely on a wire rack to prevent condensation, which ruins the crust. For long-term storage, freeze fully cooled loaves wrapped in plastic—they reheat beautifully in a 350°F oven for 10 minutes.

Step-by-step instructions for 75% hydration sourdough bread

This method delivers professional-quality sourdough with minimal handling and maximum oven spring.

In a large mixing bowl, combine the 0.5 cup Active Sourdough Starter with 2.25 cups Filtered Water at 75°F-78°F. Let this sit for 5 minutes while you prepare the dry ingredients. In a separate bowl, whisk together the 3.5 cups Unbleached All-Purpose Flour, 1.5 cups Bread Flour, 1 tbsp Instant Vital Wheat Gluten, and 1.5 tsp Kosher Salt. The gluten blend should be completely homogeneous before proceeding.

After the 5-minute wait, add the flour mixture to the wet starter and water. Using a dough whisk or your hands, mix until a shaggy dough forms. This high-hydration dough will be sticky—don't fight it. Add 1 tbsp Extra-Virgin Olive Oil and mix thoroughly. The dough should be smooth and elastic, with a slight sheen indicating proper hydration. If it's too stiff, add 1 tablespoon of the Filtered Water; if too wet, add 1 tablespoon of the flour mixture. Cover the bowl and let rest for 30 minutes at room temperature.

After the initial rest, perform a 45-minute autolyse by mixing the dough again just until combined. This step allows gluten to relax and develop naturally without additional handling. The dough should feel slightly tacky but cohesive. Wet your hands with water and perform 20 gentle stretch-and-folds every 15 minutes during the autolyse. This builds structure without overworking the dough.

During the stretch-and-folds, focus on creating surface tension. Gently grab one side of the dough and stretch it upward while rotating the bowl, then fold it over itself. Repeat this motion around the bowl's circumference. The dough should become smoother and more elastic with each set. After the final set, cover and let rest for 15 minutes before the final bulk fermentation.

Transfer the dough to a lightly oiled bowl, seam-side up, and cover with a damp towel. Place in a warm environment (78°F-80°F) for 3-4 hours, performing 2 sets of stretch-and-folds at 30-minute intervals. The dough should increase in volume by 50-75% and exhibit bubbles on the surface. If the dough doesn't rise significantly after 4 hours, it may need additional time—check for readiness by performing the "poke test": gently press your finger into the dough. If it springs back slowly and leaves a slight indentation, it's ready.

Once properly fermented, add the 0.5 cup Ice Water and mix gently until fully incorporated. This final addition helps strengthen the dough's structure before shaping. Let the dough rest for 20 minutes before shaping to allow the ice water to integrate completely. The dough should feel slightly firmer but still pliable.

Lightly dust a work surface with 0.25 cup Cornmeal and turn out the dough. Using a bench scraper, divide the dough into 4 equal portions. Shape each portion into a tight boule by gathering the dough into a ball, sealing the seam, and rotating the boule to tighten the surface. Place the shaped boules seam-side up in a floured banneton or bowl, cover, and refrigerate for 12-16 hours to proof slowly in the cold.

The cold proofing develops flavor and strengthens the gluten structure. When ready to bake, turn out the boules onto a piece of parchment paper, seam-side down. Create steam in your oven by placing a baking sheet with 1 cup hot water on the lower rack. Bake at 450°F for 20 minutes, then reduce heat to 425°F and bake for an additional 20-25 minutes until the internal temperature reaches 205°F and the crust is deep golden brown.

Remove the bread from the oven and transfer to a wire rack. Avoid slicing immediately—the bread needs 1-2 hours to fully set and release steam. The internal temperature should drop to 140°F before slicing for optimal texture. The crust should be crisp and shatterable, while the crumb should be open and airy with visible holes.

This method yields a loaf with excellent oven spring and a well-developed crumb structure. The high hydration and proper gluten development create a bread that's both visually stunning and delicious. Store wrapped at room temperature for up to 3 days or freeze for longer storage.

Pro cooking tips for this dish

Autolyse Mastery

The 45-minute autolyse is where gluten development begins in earnest. This resting period allows the flour's proteins to hydrate fully and form a relaxed network without your hands interfering. I recommend using a large stainless steel bowl (like the OXO Good Grips) because it won't absorb moisture or flavors.

During this time, the dough should become smoother and more cohesive—almost like a thick pudding. If your kitchen is cool (70°F or below), extend the autolyse to 60 minutes to prevent overworking later. 🌡️

Stretch-and-Fold Precision

Timing and technique matter most during stretch-and-folds. Use wet hands (dipped in water) to prevent sticking, and focus on creating surface tension—grab one edge, stretch upward, then fold it over the center. Rotate the bowl 90 degrees and repeat.

I find 20 total stretches (5 per side) during autolyse builds structure without overworking. If your dough resists stretching, it may need 5 more minutes of rest before continuing. The goal is to develop gluten gradually, not all at once.

Bulk Fermentation Control

Your 78°F-80°F fermentation environment is critical—use an oven with a baking stone (preheated to 140°F) or a proofing box like the Breville Smart Oven. The dough should nearly double in size with visible bubbles.

If it rises too quickly, move it to a cooler spot (75°F) to prevent overproofing. I always do a poke test: press gently with a finger. If it springs back slowly with a slight indentation, it's perfect. If it springs back immediately, it needs more time. 💡

Cold Proofing Secrets

Cold proofing in the fridge for 12-16 hours is where flavor develops. The slow fermentation creates complex sugars and acids. I use parchment-lined bowls to prevent sticking and cover them with plastic wrap (not cloth) to lock in moisture.

When ready, the dough should feel slightly firmer but still springy. For extra flavor, I sometimes add 1 tsp honey to the dough before cold proofing—it feeds the yeast and enhances crust color.

Scoring Like a Pro

Scoring isn't just decoration—it directs oven spring. Use a sharp razor (or lamé) and cut ½-inch deep at a 45-degree angle in a crosshatch pattern. The cuts should be clean and precise, not jagged. I dip the blade in hot water first to prevent sticking.

For a boule, make 3-4 diagonal cuts; for a batard, use 2 parallel cuts. The steam from your oven will make the crust rise dramatically along these lines. ✨

Steam Generation Hacks

Steam is non-negotiable for that crusty exterior. I use two methods: either place a baking sheet with 1 cup boiling water on the oven floor, or spray the dough with water right before baking.

For extra drama, I add ice cubes to the hot water—the temperature shock creates more steam. The oven should feel humid when you open the door after 5 minutes. If your oven lacks steam, consider a steam-injector attachment for your oven door.
