75% Hydration Sourdough Bread Recipe: No-Knead Rise to Airy, Tangy Perfection

This 75% hydration sourdough bread recipe delivers restaurant-quality loaves with a crisp crust and airy, open crumb—no kneading required. The secret lies in precise hydration and a slow, controlled fermentation that develops deep flavor and structure.

After years of experimenting, I've perfected a method that yields consistent results even for beginners.

The magic begins with a well-fed starter and the right flour blend—bread flour for strength, all-purpose for tenderness. We'll use a no-knead approach with strategic stretch-and-folds to build gluten gradually.

The key to that signature oven spring? Properly timed shaping and a steamy baking environment. Every element works together to create bread that's both visually stunning and delicious.

What you'll achieve is a loaf with a golden, crackly crust and an interior filled with large, irregular holes—proof of proper fermentation. The tangy flavor comes from the starter, while the texture remains light and airy despite the high hydration.

This technique transforms what could be a challenging bake into a reliable, impressive result.

Whether you're baking for daily sandwiches or special occasions, this method delivers professional-quality bread with minimal effort. The same principles apply whether you're using a Dutch oven or baking stone. Let's get started on creating your perfect loaf.

Ingredients for 75 hydration sourdough bread

The perfect blend of flour, hydration, and fermentation creates restaurant-quality sourdough with minimal effort.

Your starter is the foundation—it should be active and bubbly with a 100% hydration ratio. King Arthur or Caputo bread flours provide the best gluten structure, but any high-protein flour works. The all-purpose flour adds just enough tenderness to balance the open crumb. For the starter, I always use a fed ratio of 1:1:1 (starter:flour:water) 4-6 hours before mixing. If your starter smells overly sour or has a grayish tint, feed it twice more before using. The sugar isn't just for flavor—it helps feed the starter and promotes that beautiful golden crust during baking.

No bread flour? Substitute with all-purpose plus 1 tbsp vital wheat gluten per cup—it mimics the protein structure. Short on time? Add the optional instant yeast (0.01 oz) for a slightly faster rise, but the tangy flavor will be less pronounced. For scoring, a razor blade or lame creates clean cuts, but a sharp knife works in a pinch. The olive oil isn't just for the dough—drizzle a little on the scored loaf before baking for extra shine. If you're baking without a Dutch oven, place a baking stone on the bottom rack and add ice cubes to a tray on the oven floor for steam.

This dough ferments best at room temperature (70-75°F) for 12-16 hours, but it's flexible—up to 24 hours for deeper flavor. For storage, wrap cooled loaves in beeswax wrap or a cotton towel to keep them fresh for 3-4 days. Freeze fully cooled loaves for up to 3 months—thaw at room temperature before slicing. Pro tip: Toast slices straight from the freezer for crispy, restaurant-quality results. The cornmeal isn't just for dusting—sprinkle it on your work surface and the scoring blade to prevent sticking during shaping.

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

Here's how to transform simple ingredients into a light, airy loaf with an open crumb and perfect tang.

In a large mixing bowl, combine the 0.5 cup active sourdough starter, 1.5 cups water, 0.02 oz granulated sugar, and 0.75 tsp salt. Let this sit for 10 minutes while you prepare the remaining ingredients. This initial hydration jumpstarts fermentation and ensures even distribution of flavor.

Next, add the 3 cups bread flour and 0.5 cup all-purpose flour to the bowl. Using a dough whisk or wooden spoon, mix vigorously for 5 minutes until the dough becomes shaggy and begins pulling away from the sides. The goal here is to fully hydrate the flour while developing just enough gluten for structure. You'll notice the dough will be wetter than traditional sourdough—this is normal for 75% hydration.

Finally, drizzle in the 0.5 tbsp olive oil and fold it into the dough using a rubber spatula. The oil adds tenderness and helps create that beautiful open crumb. Cover the bowl with a damp kitchen towel and let it rest at room temperature for 30 minutes. This rest period allows the flour to fully absorb the liquid and the gluten to begin relaxing.

After the initial rest, perform a series of stretch and folds every 30 minutes for 2 hours. To do this, wet your hands to prevent sticking, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat this motion on all four sides. This technique strengthens the gluten structure without overworking the dough.

During the bulk fermentation, the dough will rise significantly—you're looking for 50-75% increase in volume. The ideal point is when the dough springs back slowly when poked with a finger (about 4-6 hours total, including the initial 30-minute rest). Temperature matters here: aim for a 75-78°F environment. If your kitchen is cooler, extend the fermentation time by 1-2 hours. You'll know it's ready when you see large bubbles on the surface and the dough has a jiggly, almost liquid center.

Once the dough reaches peak fermentation, it's time for the final shaping. This is where the magic happens—proper shaping creates that signature open crumb we're after.

Lightly dust a clean work surface with 0.25 cup cornmeal. Turn out the fermented dough and gently shape it into a round boule by pulling the edges toward the center while rotating the dough. As you work, use the cornmeal to prevent sticking—this will also create that beautiful cornmeal crust on the bottom of your loaf.

Place the shaped boule seam-side up in a well-floured banneton or bowl. Cover with a damp towel and refrigerate for 12-16 hours. The cold slows fermentation while allowing the dough to develop flavor. This overnight proof is crucial for the open crumb structure—it gives the gluten time to fully relax and the yeast time to work slowly, creating those beautiful air pockets.

Before baking, turn out the dough onto a piece of parchment paper. Use a razor blade or sharp knife to score the dough in a crosshatch pattern—this prevents the loaf from bursting open during baking and creates that classic sourdough crust. The score should be about 1/8-inch deep and cut through to the dough underneath.

Preheat your Dutch oven with lid in a 475°F oven for 45 minutes. While it heats, place 0.5 cup ice cubes in a small bowl—this will create steam during baking. Carefully transfer the scored dough (on parchment) into the hot Dutch oven. Quickly pour the ice cubes onto the oven floor, then place the lid on the Dutch oven.

Bake for 20 minutes with the lid on, then remove the lid and continue baking for 20-25 minutes until the internal temperature reaches 205-210°F. You'll know it's done when the crust is a deep golden brown and sounds hollow when tapped on the bottom. The steam from the ice cubes creates that perfect oven spring and crackly crust.

Remove the bread from the Dutch oven and let it cool on a wire rack for at least 1 hour before slicing. This resting period allows the crumb to set and prevents a gummy texture. The longer you wait, the better the structure will be—patience here is key. Once cooled, slice into ½-inch thick pieces to reveal that beautiful open crumb and tangy flavor.

Make-ahead tips for this 75 hydration sourdough bread

Pre-Ferment Prep

Mix your dough the night before and refrigerate it overnight for a hands-off approach. After the initial 30-minute rest and 2-hour stretch-and-fold session, cover the bulk fermentation bowl tightly with plastic wrap and refrigerate for 12-16 hours.

This cold fermentation slows yeast activity while allowing time for deep flavor development. The next morning, simply remove it from the fridge, let it sit at room temperature for 1-2 hours to come to proofing temperature, then proceed with shaping and baking. 🌙

Dough Portioning

Divide your dough into individual portions before bulk fermentation if you plan to bake multiple loaves. Weigh each portion to 500g for consistency—this ensures even baking and fermentation. Store portions in separate airtight containers or zip-top bags in the fridge for up to 48 hours.

When ready to bake, remove a portion and let it sit at room temperature for 2 hours before shaping. This method works perfectly for meal prep—just bake one loaf at a time as needed. ⏰

Freezer-Friendly Dough

For ultimate convenience, prepare and shape your dough, then freeze it before the final proof. Place shaped boules in a freezer bag with parchment paper between them to prevent sticking. Thaw overnight in the fridge, then proceed with scoring and baking as usual.

The cold proof after thawing will take 4-6 hours instead of the usual 2 hours, so plan accordingly. This technique is perfect for busy weekends or holiday baking. 🧊

Proofing Shortcuts

If you're short on time, use a proofing box (or even a repurposed slow cooker with a bowl of warm water) to speed up fermentation. Set the temperature to 80°F and proof your shaped dough for 1.5-2 hours instead of overnight.

For scoring, keep a razor blade and cornmeal prepped in a small container—this makes the final steps quick and efficient. The trade-off is slightly less flavor development, but you'll still get great results. ⚡

Storage Solutions

Store freshly baked loaves in a bread box or cotton towel-lined basket at room temperature for 2-3 days to maintain freshness. For longer storage, wrap cooled loaves in beeswax wrap and freeze for up to 3 months.

To revive frozen bread, thaw at room temperature for 1 hour or toast slices directly from frozen for crispy results. The freezer method preserves moisture and flavor better than plastic bags. 💫

Batch Baking

Double or triple your recipe and freeze shaped boules for weekly baking. Label each bag with the date and thaw one portion at a time. This system ensures you always have fresh sourdough on hand without the weekly effort.

For variety, try shaping some portions as batards (long loaves) or baguettes
