Whether you’re baking for a family dinner or meal prepping for the week, this all-purpose sourdough will become a staple. Let’s get started on creating your perfect loaf—one that’s as rewarding to make as it is delicious to eat.

Ingredients for all purpose sourdough bread

Four cups of flour kickstart this transformative sourdough journey toward perfect crusty crunch and airy crumb.

The sourdough starter is your foundation—King Arthur or a trusted home starter both work, but it must be active and bubbly. Whole Foods or local bakeries often have pre-mixed starters if you're just starting. For flour, King Arthur Bread Flour gives the best structure, but any high-protein flour (12%+ protein) will do. The whole wheat flour adds depth, but if you're avoiding gluten, swap it for extra all-purpose. Butter is non-negotiable here—Plugrá or Land O'Lakes unsalted melt beautifully for that tender crumb. Keep everything cold until mixing to prevent over-proofing.

No bread flour? All-purpose plus 1 tbsp vital wheat gluten mimics the protein content perfectly. Short on butter? Olive oil at half the amount works, though the texture won't be quite as tender. The sugar can be swapped for honey (reduce by 1 tsp) if you prefer. For scoring, if semolina is unavailable, rice flour or extra all-purpose works in a pinch. The water temperature matters—too hot and you'll kill the yeast; too cold and fermentation slows. 75°F is ideal, but room temp water usually hits that mark. If your kitchen runs cold, let the water sit for 10 minutes before using.

Fermented dough keeps 24 hours in the fridge—perfect for shaping the next day. For scoring, a razor blade gives the cleanest cuts, but a sharp serrated knife works too. Baked loaves stay fresh 3 days at room temperature wrapped in a cotton towel, or 1 week frozen in slices. To revive stale bread, warm slices in a 350°F oven for 5 minutes with a splash of water. The butter should be cold when cubed—freeze it 10 minutes if your kitchen feels warm.

Step-by-step instructions for all-purpose sourdough bread

Here's how to transform your active starter into a loaf with perfect crust and open crumb.

In a large mixing bowl, combine the 0.5 cup active sourdough starter, 2.25 cups water, 1 tbsp olive oil, 1 tbsp granulated sugar, and 1.5 tsp salt. Use your hands or a dough whisk to mix until the sugar and salt dissolve completely. This wet mixture should be slightly tacky but not liquidy—you'll be adding dry ingredients next.

Here's the thing—I always let this wet mixture sit for 5 minutes before adding flour. This gives the starter time to begin activating, which improves gluten development later. The mixture should look like a thin batter with small bubbles forming on the surface.

Gradually add the 4 cups all-purpose flour and 0.5 cup whole wheat flour to the wet mixture, mixing with a wooden spoon or your hands until just combined. You'll want to use the "scrape and fold" technique—lift the dough from the bottom of the bowl and fold it over itself to incorporate air and strengthen the gluten.

After about 5 minutes of mixing, the dough should come together into a shaggy mass that's still slightly sticky but manageable. If it's too wet, add 1 tablespoon of all-purpose flour at a time until it holds together when pressed. The whole wheat flour adds wonderful texture and flavor, but too much can make the dough too dense.

Cut the 0.25 cup unsalted butter into small cubes and distribute them evenly over the surface of the dough. Use your hands to gently work the butter into the dough, pressing it down and folding it in. The butter should begin to soften slightly but should still feel cool to the touch.

This is where the magic happens—the cold butter creates little pockets of fat that will melt during baking, creating that beautiful open crumb structure. Work the butter in for about 2-3 minutes until it's fully incorporated and the dough becomes smoother. If the dough feels too warm, place the bowl in the refrigerator for 5 minutes to firm it up.

Turn the dough out onto a lightly floured surface and knead for 8-10 minutes until smooth and elastic. I like to use the "windowpane test" to check gluten development—stretch a small piece of dough thin enough to see light through it. If it doesn't tear, your gluten is developed properly.

During kneading, you'll notice the dough becomes less sticky and more cohesive. This step is crucial for creating the right texture—underkneaded dough results in a dense loaf, while overkneaded dough can become tough. The whole wheat flour will make the dough slightly more resistant, so be patient and keep kneading until it passes the windowpane test.

Shape the dough into a loose round and place it back in the mixing bowl. Cover the bowl with a damp kitchen towel and let it ferment at room temperature (70-75°F) for 4-6 hours, or until it has roughly doubled in size. You'll see bubbles forming on the surface and the dough will feel springy when pressed gently.

This is the most critical step for flavor development. The longer you ferment, the more complex flavors you'll get, but don't exceed 8 hours or the dough may overproof. I like to check the dough every 30 minutes during the last hour of fermentation—it should feel light and airy, with noticeable bubbles throughout.

Dietary considerations for this dish

Gluten-Free Adaptations

For a gluten-free version, replace the 4 cups all-purpose flour and 0.5 cup whole wheat flour with a 1:1 gluten-free flour blend (like Bob's Red Mill 1-to-1) and add 1 tbsp xanthan gum to mimic gluten's elasticity.

The butter and starter remain the same, but expect a denser crumb—gluten-free dough lacks the same structure. Let the dough ferment 1-2 hours longer since gluten-free flours ferment slower. 🌾

Low-Carb/Keto Options

Transform this into a low-carb loaf by swapping 3 cups of the all-purpose flour for 3 cups almond flour and 0.5 cup coconut flour. Reduce water to 1.75 cups since these flours absorb less moisture.

The dough will be crumbly, so handle it gently and avoid over-kneading. Ferment for only 2-3 hours—longer fermentation can make it gummy. Bake at 375°F for 30-35 minutes to prevent burning.

Vegan Substitutions

Replace the 0.25 cup unsalted butter with 0.25 cup vegan butter (like Miyoko's) or coconut oil for a dairy-free version. For an egg wash alternative, brush the baked loaf with olive oil mixed with water (1:1 ratio).

The starter remains vegan if made with plant-based ingredients, but ensure your flour and salt are certified vegan. The texture will be slightly denser but still delicious.

Allergen-Friendly Tips

For nut allergies, use a gluten-free oat flour blend instead of almond flour. If avoiding dairy entirely, opt for coconut oil or avocado oil instead of butter. Always check labels—some gluten-free flours contain trace amounts of nuts or dairy.

When in doubt, use separate utensils and surfaces to avoid cross-contamination. A little extra care ensures everyone can enjoy this bread safely. ✨

Sugar-Free Version

Omit the 1 tbsp granulated sugar entirely—it’s not essential for structure, just flavor. For a subtle sweetness, add 1 tsp monk fruit sweetener or 1 tbsp erythritol (both are low-carb and won’t affect fermentation).

The dough may rise slightly slower without sugar, so monitor fermentation closely and extend it by 30-60 minutes if needed. The crust will be less golden, but the flavor remains rich and tangy.
