At a Glance
A moist, gluten-free sourdough loaf using buckwheat and binder flours for structure. Long, cool fermentation improves flavor and digestibility; hydration and gentle handling are key to avoid collapse. Techniques adapted from traditional sourdough principles apply even without gluten [1][2].
Not suitable if:
- • You need a nut-free bread (contains buckwheat and optional seeds/nuts) → see alternatives
- • You don't have an active gluten-free starter → create a starter

Ingredients
Weigh all ingredients on a kitchen scale. Gluten-free formulas are weight-sensitive; accuracy improves consistency [1].
| Ingredient | Amount | % | Note |
|---|---|---|---|
| Buckwheat flour | 300g | 60% | Toasted lightly for deeper flavor (optional) |
| Brown rice flour | 100g | 20% | Adds body and mild flavor |
| Tapioca starch | 50g | 10% | Provides chew and structure |
| Sorghum flour | 50g | 10% | Optional — improves crumb |
| Water | 520g | 104% | High hydration produces a batter-like dough |
| Active gluten-free starter | 150g | 30% | Fed and bubbly, made from gluten-free flour |
| Salt | 10g | 2% | |
| Xanthan gum | 4g | 0.8% | Improves crumb elasticity; optional if using other binders |
| Sunflower seeds (optional) | 60g | 12% | Soak 15 min and drain to avoid drawing moisture |
Schedule
Weekend Version
Relaxed schedule with room-temperature bulk
Weekday Version
Mix at night and slow-proof in fridge
💡 Tips
- If dough overferments at room temperature → cool in fridge to slow activity [1]
- Shaped dough keeps 48 hours in fridge; gluten-free starters tend to be less predictable, so use cold-proof as a timing buffer [2]
Step by Step
Mix ingredients
Combine dry flours and starch in a large mixing bowl. Mix water and starter separately, then pour into dry mix. Add salt and xanthan gum. Stir vigorously with a dough scraper or whisk until a smooth, batter-like dough forms. Gluten-free doughs will be wetter than wheat doughs; this hydration yields a tender crumb [1].
⏱ 10-15 minutes
Autolyse (rest)
Cover the bowl and let rest 30-60 minutes. Hydration allows starches to swell and binders to hydrate, improving handling and crumb [1].
⏱ 30-60 minutes
Add seeds and final mix
Fold in drained seeds or nuts with a dough scraper so they are evenly distributed. This is gentle—don't overmix.
⏱ 2-3 minutes
Bulk fermentation
Cover and ferment at 70-75°F / 21-24°C until batter increases in volume ~30-50% and shows small bubbles. Gluten-free starters produce less visible oven spring, so rely on smell and slight volume increase [2].
⏱ 4-8 hours (depends on starter strength)
Shape
Dust a work surface with rice flour. Use a dough scraper to transfer batter; with floured hands, shape gently into a loaf form and place seam-side down into a lined tin or rice-floured banneton. For loose batter, line the basket with parchment.
⏱ 10 minutes
Final proof
Cover and proof until the loaf shows slight rise and the surface looks airy. For predictable timing, proof in the fridge 8-16 hours. Cold proof enhances flavor and makes scoring easier [1][2].
⏱ 1.5-3 hours at room temp, or 8-16 hours in fridge
Bake
Preheat oven to 460°F/240°C with a Dutch oven or cloche inside for 30-45 minutes. Transfer loaf on parchment paper, score lightly with a bread lame if desired. Bake covered 20-25 minutes to generate steam, then uncover and reduce to 400°F/200°C for 25-40 minutes until deeply browned. Internal temperature target: 205°F/96°C measured with an instant-read thermometer [1].
⏱ 45-70 minutes depending on loaf size
Cool
Remove from oven with oven mitts and cool on a wire rack for at least 2 hours. Cutting too early yields gummy crumb because residual starches haven't set [2].
⏱ 2+ hours
Tips & Variations
Variations
Seeded Buckwheat
Increase seeds to 100g (sunflower, pumpkin)
→ More texture and nutty flavor
Lightly Sweetened
Add 1 tbsp honey or maple syrup to water
→ Softer crumb and deeper crust color
No-Xanthan Option
Use 30g psyllium husk husk powder instead of xanthan
→ Better water retention and crumb elasticity
Pro Tips
- 💡 Toast buckwheat flour briefly for a nuttier aroma; cool before mixing
- 💡 Use a digital kitchen scale for consistency—small weight changes shift hydration significantly [1]
- 💡 Slice the cooled loaf with a serrated bread knife; crumb firms further after 24 hours
Common Issues
If things go wrong, check these common gluten-free issues:
Storage
Room temperature (paper bag or bread box)
4-5 days
Wrap cut side down to retain moisture
Kitchen towel
3-4 days
Breathable wrap prevents sogginess
Freezing
3 months
Slice before freezing; toast slices straight from frozen
⚠️ Avoid refrigerating — starch retrogradation accelerates staling, shortening shelf life [2]
