Mastering 100% spelt sourdough bread transforms your kitchen into a bakery—nutty, complex crusts and an open, airy crumb that defies store-bought loaves. This recipe builds on years of testing, where I discovered spelt’s natural sweetness and protein content create a dough that’s both forgiving and extraordinary.
The key? A slow starter and precise hydration balance that yields a loaf with golden, crackly edges and a tender interior that crumbles like clouds.
Unlike traditional wheat sourdough, spelt demands patience but rewards with a flavor profile that’s subtly sweet, earthy, and deeply satisfying. We’ll start with a robust starter (or use a pre-made one), then focus on a 36-hour fermentation at cool temperatures—this develops the bread’s signature depth.
The shaping technique ensures an even rise, while baking at 425°F creates that coveted crispy crust without drying the crumb.
What you’ll achieve is a loaf that’s restaurant-quality at home—no kneading, no guesswork, just science-backed steps that deliver consistent results. The nutty aroma fills your kitchen as it bakes, and every slice reveals an open crumb with just the right chew.
Perfect for breakfast, sandwiches, or gifting, this bread proves sourdough isn’t just a skill—it’s an art you can master.
Optional additions like flaxseeds or rosemary elevate flavor further, but the base recipe stands alone as a testament to spelt’s potential. Ready to bake a loaf that’ll impress even seasoned bakers? Let’s begin with the starter—your journey to perfect spelt sourdough starts here.
Ingredients for 100 spelt sourdough bread
Four cups of spelt flour kickstart this transformative sourdough journey—nutty, complex, and unforgettable.
| Ingredient | Amount | Notes |
|---|---|---|
| Spelt Flour 🌾 | 4 cups | Organic preferred for best flavor |
| Active Sourdough Starter 🍞 | 1 cup | 100% hydration, bubbly and active |
| Warm Water 💧 | 2 ½ cups | Filtered, 75°F for ideal fermentation |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal preferred for purity |
| Extra-Virgin Olive Oil 🫒 | 1 tbsp | For dough handling and crust |
| Flaxseeds (optional) 🌰 | ¼ cup | For added texture and nutrition |
| Rosemary (optional) 🌿 | 1 tbsp | Finely chopped, for aromatic depth |
| Cornmeal 🌽 | ¼ cup | For dusting the baking surface |
| Ice Water (for scoring) ❄️ | ½ cup | Chilled for crisp score lines |
Spelt flour is the heart of this recipe, and King Arthur or Bob’s Red Mill are my go-tos for consistent results. Look for organic spelt flour if possible—it enhances that natural sweetness and earthy depth. The starter is non-negotiable; if you don’t have one, King Arthur’s sourdough starter kit is a game-changer. For the water, filtered is best—tap water can vary too much in mineral content, which affects fermentation. The optional flaxseeds and rosemary? Buy them whole—they keep longer and you control the grind. Store-bought pre-ground spices lose flavor fast.
No sourdough starter? Make one in 5 days with spelt flour and water—just feed it daily. Short on time? Store-bought starter works too, but feed it 24 hours before using to wake it up. Swapping flaxseeds? Sunflower seeds or pumpkin seeds work equally well. Rosemary too strong? Thyme or oregano add subtle aroma without overpowering. The olive oil matters—avoid cheap brands; you’ll taste the difference in the crust’s richness. For scoring, a razor blade or sharp knife creates those crisp lines—no need for fancy tools.
Spelt dough ferments best in the fridge—cover tightly for up to 3 days if you need to slow things down. The starter itself keeps 1 week in the fridge, fed weekly. For scoring, chill the water first—it makes the dough tighter and the cuts sharper. Baked loaves stay fresh 5 days at room temperature, wrapped in a cotton towel. Freeze slices for 3 months—toast straight from frozen for crispy perfection.

Step-by-step instructions for spelt sourdough bread mastery
Here’s how to craft a loaf with a nutty crust and open, airy crumb—every detail matters.
Mix the Dough for Optimal Fermentation
In a large mixing bowl, combine the 4 cups spelt flour with the 1 cup active sourdough starter and 1.5 tsp kosher salt. Create a well in the center and pour in the 2.5 cups warm water (about 75°F). Stir with a wooden spoon until just combined—you should have a shaggy, sticky dough that clings to the sides of the bowl.
Add the 1 tbsp extra-virgin olive oil and, if using, the 0.25 cup flaxseeds and 1 tbsp finely chopped rosemary. Mix again until evenly distributed. The dough will feel tacky, but resist the urge to add more flour—this is normal for spelt. Cover the bowl with a damp kitchen towel and let it rest for 30 minutes at room temperature. This initial rest helps the gluten relax and the dough come together more easily.
Develop the Dough Through Bulk Fermentation
After the rest, wet your hands with water and perform a series of stretch-and-folds every 30 minutes for 2 hours. To do this, grab one side of the dough, stretch it upward, and fold it over itself. Rotate the bowl and repeat, working your way around the dough. This builds strength and creates the open crumb structure we want. The dough should become smoother and more elastic with each fold.
After the final stretch-and-fold, cover the bowl again and let the dough ferment at room temperature for 4-6 hours, or until it has nearly doubled in size and feels light and airy when pressed gently. You’ll know it’s ready when the dough springs back slowly when poked with a finger—this indicates proper fermentation. If using a digital scale, aim for a 20-30% increase in weight.
Shape and Proof the Dough for Structure
Lightly flour a clean surface and turn out the dough. Gently shape it into a loose round by pulling the edges toward the center and tucking them under. Place the dough seam-side up in a lightly oiled 9×5-inch loaf pan (or a banneton if making a free-form loaf). Cover with a damp towel and let it proof for 1-2 hours until it rises 1-2 inches above the rim of the pan. The dough should feel jiggly and have a slight domed shape.
If the dough isn’t rising as expected, place it in a warmer spot (like near the oven with the light on) to encourage fermentation. Avoid over-proofing—this can lead to a dense crumb. Once proofed, preheat your oven to 425°F with a Dutch oven inside for 30 minutes to create a steamy environment for baking.
Bake for a Crisp Crust and Open Crumb
Carefully remove the Dutch oven from the oven and transfer the proofed dough into it. If the dough springs back when poked, it needs more proofing—let it sit for another 15-30 minutes while the oven finishes preheating. Sprinkle the 0.25 cup cornmeal evenly over the top of the dough for texture. Bake, covered, for 30 minutes, then remove the lid and bake for another 15-20 minutes until the crust is deep golden brown and sounds hollow when tapped.
For scoring, brush the top with the 0.5 cup ice water using a pastry brush, then use a sharp razor or lame to make ½-inch deep cuts in a crosshatch or diagonal pattern. This allows the bread to expand properly and creates those beautiful crust details. The internal temperature should reach 205-210°F when fully baked.
Cool and Enjoy for Perfect Texture
Remove the bread from the Dutch oven and place it on a wire rack to cool completely for at least 1 hour before slicing. This step is crucial—cutting too soon traps steam and makes the crumb gummy. The bread will continue to set as it cools, developing that signature nutty aroma and crisp exterior.
Slice into ½-inch thick pieces and serve warm with olive oil or your favorite spread. The crust should be shatteringly crisp with a hint of caramelization, while the crumb should be open and airy with a delicate, nutty flavor. Store any leftovers wrapped in a cloth-lined bag at room temperature for up to 3 days—this bread tastes best fresh!
Pro Tips For Making 100 Spelt Sourdough Bread
- Autolyse First: Mix the spelt flour and warm water alone for 30-60 minutes before adding starter or salt—this hydrates the flour fully and makes kneading (or stretching) easier. I learned this the hard way after fighting with sticky, tough spelt dough for years.
- Test Starter Density: Your active starter should float in water like a buoy when fully ripe—this means it’s at peak strength for the 100g you’re using. If it sinks, feed it 1:1:1 (flour:starter:water) 2 hours before mixing; spelt needs a lively starter to rise properly.
- Skip the Over-Kneading: Spelt’s sticky gluten resists overwork—stop when the dough springs back slowly (not instantly) when poked. I used to punch it down like wheat dough and ended up with dense, gummy loaves every time.
- Oil the Bowl: Coat your mixing bowl with 1 tablespoon of extra-virgin olive oil before bulk fermentation—prevents the spelt dough from sticking to the sides and guarantees a smoother handle. Yes, even if your recipe doesn’t call for it.
Best sauces and condiments for this dish
Olive Oil Drizzle
Finish your spelt sourdough with a generous drizzle of extra-virgin olive oil right after baking. I use 2 tbsp of California Gold Organic—its fruity notes complement the bread’s nutty flavor beautifully. Brush it warm for a glossy finish that enhances the crust’s caramelization. 🌿
Honey Butter
Combine ½ cup softened butter with 2 tbsp wildflower honey and a pinch of sea salt for a luxurious spread. Warm the mixture gently until the honey melts, then let it cool slightly before spreading. This sweet-savory combo elevates every slice, especially when paired with fresh fruit or charcuterie. 🍯
Whole Grain Mustard
Mix 2 tbsp Dijon mustard with 1 tbsp olive oil and a splash of apple cider vinegar for a tangy contrast. The mustard’s sharpness cuts through the spelt’s earthiness, while the vinegar adds brightness. Use it as a spread or dip for sandwiches—it’s a game-changer for open-faced toast. 🌶️
Herbed Compote
Simmer 1 cup crushed tomatoes, 1 tbsp balsamic vinegar, 1 tsp dried oregano, and 1 minced garlic clove until thickened. Finish with a swirl of olive oil and a pinch of sugar.
This jammy topping adds depth to toasted slices, balancing the bread’s natural sweetness. Perfect for brunch or light meals. 🍅
Nut and Seed Butter
Blend ½ cup roasted almonds with 2 tbsp tahini and 1 tsp maple syrup for a rich, nutty spread. The almonds amplify the spelt’s flavor while adding protein and crunch. Spread thickly on toast or use as a filling for sandwiches—this combo is pure indulgence. 🌰
Spiced Whipped Feta
Whip 1 cup crumbled feta with 2 tbsp heavy cream, 1 tsp honey, and ½ tsp smoked paprika until fluffy. The salty tang of feta contrasts the spelt’s nuttiness, while the paprika adds warmth. Top with cracked black pepper for a restaurant-worthy finish. 🧀

Frequently asked questions
Why does spelt sourdough need a longer fermentation than wheat?
Spelt’s higher protein content and natural sweetness require extra time to develop flavor and texture. The 36-hour fermentation breaks down complex sugars, creating that signature nutty depth and open crumb. Wheat sourdough often ferments faster because its gluten structure is more elastic—spelt needs patience to achieve its signature tenderness.
Can I substitute whole wheat flour for spelt?
Not directly—spelt has a unique protein structure that creates a lighter, airier crumb. Whole wheat would make the bread denser and heavier. For a similar texture, try a 50/50 mix of spelt and whole wheat flour, but expect a slightly different flavor and crumb structure. The nutty notes of pure spelt are worth the wait!
What if my spelt dough doesn’t rise properly?
Check your starter first—it should be bubbly and active when you use it. If the dough isn’t rising, try moving it to a warmer spot (like near the oven light) or extend fermentation by 2-4 hours. Cold temperatures slow fermentation, while warm environments speed it up. Overproofing is another culprit—stop when the dough springs back slowly when poked.
How do I know when the bread is fully baked?
Look for a deep golden brown crust and listen for a hollow sound when tapped on the bottom. The internal temperature should reach 205-210°F. If unsure, slice into the center—it should be fully set with no raw spots. Underbaking leaves a gummy crumb, while overbaking dries it out.
Can I make this bread without a Dutch oven?
Yes! Use a metal loaf pan with a lid or cover tightly with foil to trap steam. For extra crispiness, place the pan on a baking sheet to catch drips. The crust won’t be as crackly, but the crumb will still be open and delicious. Preheat the oven with the pan inside for 20 minutes to mimic the Dutch oven’s steam effect.
