All Purpose Sourdough Bread Recipe: Versatile Loaf for Sandwiches and Toast

This all-purpose sourdough bread recipe transforms your kitchen into a bakery with just five simple ingredients and patience. The secret lies in the starter—whether you're activating a new one or using an established culture—creating a loaf that's perfect for sandwiches, toast, or even garlic bread.

I developed this method after years of experimenting with hydration levels and fermentation times to ensure a consistent, reliable result every time.

What sets this recipe apart is its versatility—adjust the shape for boules, batards, or classic loaves, and customize with seeds, herbs, or even whole grains. The dough undergoes a two-stage fermentation that develops deep flavor while keeping the crumb open and airy.

No special equipment is needed beyond a mixing bowl and a Dutch oven for baking, making it accessible for beginners and rewarding for experienced bakers.

By the time you pull that golden-brown loaf from the oven, you'll have a crusty exterior with a soft, slightly tangy interior that's ideal for slicing thick or toasted. The recipe includes troubleshooting tips for common issues like dense bread or overproofing, so you'll know exactly how to adjust.

Store leftovers at room temperature for a few days or freeze for freshness whenever you need it.

This isn't just bread—it's a foundation for meals, from classic grilled cheese to open-faced sandwiches. The flavor builds over time, making each loaf more delicious than the last. Let's get started on your first batch—your taste buds (and lunchbox) will thank you.

Ingredients for all purpose sourdough bread

Five core ingredients plus a little patience—this is all you need for a perfect sourdough loaf.

The sourdough starter is your foundation. If you're starting fresh, King Arthur or Bob's Red Mill flours work best for activation—just mix equal parts flour and water, feed daily for 5-7 days until bubbly. For an established starter, look for one with active bubbles and a tangy aroma. Whole wheat flour adds depth but can make dough stickier, so add it gradually. The King Arthur brand is my go-to for consistent results, but any high-protein flour works. If your starter smells like vinegar or alcohol, it's overripe—toss it and start fresh.

No whole wheat flour? Substitute with white whole wheat for a lighter texture, or skip it entirely if you're sensitive to gluten. Short on sugar? Honey or maple syrup at half the amount works beautifully—just know it'll add subtle sweetness. Salt is non-negotiable for flavor and structure, but if you're using flaky sea salt instead of kosher, reduce to 1 tsp. The olive oil isn't just for flavor—it keeps the dough supple during handling. Avocado oil is a great alternative if you're avoiding olive oil's strong taste.

Fresh starter? Keep it in a glass jar at room temperature, feeding it daily. Dough can be shaped immediately or refrigerated overnight for deeper flavor—just let it sit at room temp for 1-2 hours before baking. The finished loaf stays fresh for 3-4 days at room temperature wrapped in a towel, or up to 3 months frozen for sandwiches. For extra crunch, brush the warm loaf with melted butter and sprinkle with flaky salt right after baking.

Step-by-step instructions for all purpose sourdough bread

Here's how to transform your active starter into a beautiful, versatile loaf perfect for sandwiches or toast.

In a large mixing bowl, combine the 0.5 cup active sourdough starter, 3.5 cups all-purpose flour, 0.5 cup whole wheat flour, 0.5 tsp granulated sugar, and 1.5 tsp diamond crystal kosher salt. I use a wooden spoon first to break up any flour clumps and distribute the starter evenly throughout the dry ingredients.

Make a well in the center and gradually add the 1.25 cups water while mixing with your spoon. Once a shaggy dough forms, add the 1 tbsp extra-virgin olive oil and mix until fully incorporated. The dough should come together but still feel slightly sticky—this is perfect for our all-purpose blend. If it's too dry, add 1 teaspoon water at a time until just combined.

Cover the bowl with a damp kitchen towel and let the dough rest for 30 minutes. This autolyse stage allows the flour to fully hydrate and the gluten to begin developing naturally. You'll notice the dough becomes smoother and more cohesive during this time—this is your signal that the process is working.

After the rest, perform a series of stretch and folds every 30 minutes for 2 hours total. 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 process on all four sides. This builds strength without overworking the dough, which is especially important with our all-purpose flour blend.

After the final set of folds, cover the dough again and let it bulk ferment at room temperature (70-72°F) for 4-6 hours, or until it has roughly doubled in size. The dough should feel noticeably lighter and airy when pressed gently with one finger—it should spring back slowly rather than immediately. If your kitchen is cooler, extend the fermentation to 8 hours to ensure proper development.

During this time, I recommend placing the dough in a warm spot if your kitchen runs cold. You can create a makeshift proofing box by placing the bowl on top of your turned-off oven with the light on, or nestle it inside a turned-off microwave with a bowl of hot water nearby. The goal is to maintain a consistent 75-78°F environment for optimal fermentation.

Lightly dust your work surface with 0.5 cup unbleached all-purpose flour and turn out the dough. Gently shape it into a round boule by pulling the edges toward the center and tucking them underneath. For a more rustic look, you can shape it into a batard by forming it into an oval log and sealing the seam.

Place the shaped dough seam-side down in a lightly oiled proofing basket or bowl. Cover and let it proof for 1-2 hours or until it has risen about 50% and feels springy when pressed. The surface should look slightly domed and feel firm to the touch. If your kitchen is warm, you might need less time—watch closely to avoid overproofing.

Preheat your oven to 450°F with a Dutch oven inside for 45 minutes. This creates a steam environment that gives our all-purpose sourdough that beautiful crust and open crumb structure. Carefully transfer the dough (still in its proofing basket) to the hot Dutch oven and bake covered for 20 minutes. Remove the lid and bake uncovered for an additional 20-25 minutes until the bread reaches an internal temperature of 205-210°F and the crust is a deep golden brown.

For the best results, I recommend tapping the bottom of the loaf—it should sound hollow when fully baked. Let the bread 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 crust should be crisp, the crumb open yet tender, and the flavor a perfect balance of tangy and mild—ideal for sandwiches or toast.

Flavor customization for these flavors

Herb-Infused Variations

Add 1 tbsp fresh rosemary or thyme leaves directly to the dough during mixing for an aromatic twist. The herbs infuse beautifully during fermentation, creating subtle earthy notes perfect for sandwiches.

I like using Penzeys brand dried herbs if fresh isn't available—just reduce to 1 tsp since dried is more concentrated. 🌿

Seed and Nut Additions

Stir in 2 tbsp toasted sesame seeds, sunflower seeds, or chopped walnuts during the final 30 minutes of bulk fermentation. These add crunch and visual appeal while complementing the bread's tangy flavor.

For maximum flavor, toast your seeds/nuts in a dry pan for 3-5 minutes before adding. Store-bought seed mixes work too—just check for added salt.

Sweet Variations

Swap out 0.5 tsp granulated sugar for 1 tbsp honey or maple syrup during mixing for a subtle sweetness. This works beautifully with add-ins like chopped dried apricots or cinnamon (add ½ tsp). The sweetness balances the sourdough's tang, making this perfect for breakfast toast or French toast. 🍯

Savory Add-Ins

For a cheesy variation, fold in ½ cup shredded cheddar or Parmesan during the final proof. The cheese melts slightly during baking, creating pockets of gooey goodness.

I also love adding ¼ cup chopped caramelized onions for depth—just make sure they're cooled before mixing. This version excels as grilled cheese or in open-faced sandwiches.

Whole Grain Boost

Replace ½ cup all-purpose flour with ½ cup rye flour or spelt flour for added heartiness. These flours contribute a deeper flavor and nuttier texture. For a visual contrast, use black sesame seeds or poppy seeds as a topping.

The extra fiber makes this version more filling—ideal for hearty sandwiches or as a side with soups.

Spiced Variations

Add ½ tsp ground fennel seed or coriander during mixing for a Mediterranean-inspired twist. These spices pair beautifully with olive oil and complement the bread's natural tang. For a smoky variation, add ½ tsp smoked paprika—this works especially well with savory add-ins like roasted garlic or sun-dried tomatoes. 🌶️
