Artisan Gluten-Free Multigrain Boule

Ingredients

The Overnight Sponge

Built the night before. Adds flavor depth that no same-day GF recipe can match.

• 100g (3/4 cup) sorghum flour
• 100g (7 tablespoons) warm water (about 90F / 32C)
• 1g (1/4 teaspoon) instant yeast

The Seed Soaker

Soaked overnight alongside the sponge. Pre-hydrated seeds won't steal moisture from your crumb.

• 30g (3 tablespoons) sunflower seeds
• 15g (1 tablespoon) whole flaxseeds
• 15g (1 tablespoon) sesame seeds
• 60g (1/4 cup) warm water

Final Dough

Mixed the morning of your bake. Everything comes together here.

• 150g (1 cup + 2 tablespoons) teff flour
• 100g (3/4 cup) millet flour
• 70g (1/2 cup) tapioca starch
• 20g (3 tablespoons) whole psyllium husks
• 8g (1.5 teaspoons) fine sea salt
• 5g (1.5 teaspoons) instant yeast
• 190g (3/4 cup + 1 tablespoon) warm water (about 90F / 32C)
• 20g (1.5 tablespoons) extra virgin olive oil
• 8g (1.5 teaspoons) apple cider vinegar
• 10g (1.5 teaspoons) maple syrup or honey

Total flour: 350g

Hydration: 82%

Pro tip: Weigh everything. Volume measurements are included, but GF baking is unforgiving — a few grams off on the psyllium husk will change your texture significantly.

Equipment

Method

Build the Overnight Sponge

This is what separates this loaf from every other GF bread recipe out there. A short overnight sponge built with sorghum flour gives you fermentation flavor without the complexity of sourdough. Think of it like a poolish — simple, low-effort, high-payoff.

1. Mix the sponge. In a small bowl or jar, whisk together the sorghum flour, warm water, and a small pinch of instant yeast until smooth. It'll look like a thick pancake batter.
2. Set up the seed soaker. In a separate small bowl, combine sunflower seeds, flaxseeds, and sesame seeds with warm water. Stir, cover, and let sit alongside the sponge.
3. Cover and rest overnight. Cover both bowls loosely with plastic wrap or a plate. Leave at room temperature (68-72F / 20-22C) overnight. The sponge should be bubbly and slightly domed by morning — that's exactly what you want.

Wait: PT10H

Tip: Don't skip the sponge. It's what makes this loaf taste like actual bread instead of a science experiment.

Mix the Final Dough

GF dough doesn't behave like wheat dough. Don't look for windowpane or the classic smooth ball. What you're building here is a thick, workable mass held together by the psyllium gel instead of gluten. It'll be sticky and dense — that's right.

1. Whisk the dry ingredients. In a large mixing bowl, whisk together teff flour, millet flour, tapioca starch, psyllium husks, salt, and instant yeast until evenly combined. There should be no clumps of psyllium.
2. Combine the wet ingredients. In a separate bowl or large measuring cup, whisk together the warm water, olive oil, apple cider vinegar, and maple syrup. Then add the overnight sponge and whisk until mostly smooth — a few lumps are fine.
3. Bring the dough together. Pour the wet mixture into the dry ingredients. Mix with a stiff spatula or your hands until a thick, cohesive dough forms — about 2 minutes. Add the drained seed soaker and fold it in. The dough will be sticky and dense. That's correct. Don't add more flour.
4. Let the psyllium gel activate. Cover the bowl and let the dough rest for 5 minutes. The psyllium husks will absorb the liquid and the dough will firm up noticeably. After 5 minutes it should be workable enough to shape.

Tip: If the dough is too sticky to handle after the psyllium rest, wet your hands slightly rather than adding more flour. Extra flour will throw off the hydration balance.

Shape the Boule

GF dough won't build surface tension the way wheat dough does. What you're doing here is creating a compact, unified mass that holds its shape through the proof and into the oven. Think of it less like shaping and more like packing.

1. Prepare your banneton or bowl. Line a medium bowl or banneton with a clean towel dusted generously with a mix of rice flour and teff flour. Don't be shy — GF dough sticks aggressively.
2. Shape the boule. Turn the dough out onto a lightly oiled surface. With oiled or damp hands, fold the edges of the dough toward the center several times, rotating as you go, until you've built a rough round shape. Flip it seam-side down and use your hands to coax it into a tighter ball. It won't be as smooth as a wheat boule — that's fine.
3. Transfer to the banneton. Carefully lift the shaped boule into your floured banneton or bowl, seam-side UP. Dust the exposed bottom with more rice flour. Cover loosely with plastic wrap or a damp towel.

Wait: PT1H15M

Tip: GF dough won't double in size the way yeasted wheat dough does. Look for the dough to rise by about 50% and feel slightly lighter when you gently press the edge. That's your signal to bake.

Preheat the Dutch Oven

Start preheating about 45-60 minutes before you plan to bake. The Dutch oven needs to be screaming hot — this is what creates the steam environment that gives GF bread a real crust instead of a thick, leathery shell.

1. Preheat oven and Dutch oven. Place your Dutch oven with the lid on in the oven. Set the temperature to 475F (245C). Preheat for at least 45 minutes. Position the rack in the lower third of the oven.
2. Prepare to score. Cut a piece of parchment paper slightly larger than your loaf. When you're ready to bake, quickly turn the dough out onto the parchment, seam-side down. Work fast — you want to score and load it while the dough is still cold.
3. Score the loaf. Using a sharp lame or razor blade, score the top of the loaf with one decisive slash about 1/2 inch deep, or a simple cross pattern. GF dough is softer than wheat dough — use a confident, swift stroke rather than sawing. A wet blade helps reduce drag.

Tip: For GF bread, scoring angle matters less than blade sharpness and confidence. A dull blade drags and deflates. Replace your razor blades often — they're cheap.

Bake the Boule

GF bread needs a longer bake than wheat bread. There's more moisture in the crumb, and the psyllium gel needs enough time to fully set. Pull it too early and you'll get a gummy interior — even if the outside looks done.

1. Load the Dutch oven. Carefully remove the Dutch oven from the oven. Using the parchment as a sling, lower the scored boule into the pot. Replace the lid immediately. Return to the oven.
2. Covered bake — steam phase. Bake covered at 475F (245C) for 20 minutes. The lid traps steam from the dough, keeping the crust flexible long enough for the loaf to expand fully before it sets.
3. Uncovered bake — browning phase. Remove the lid carefully. Reduce the oven temperature to 450F (230C). Continue baking for 30-35 minutes, until the crust is deep mahogany brown. GF bread can handle more color than you'd expect — don't pull it at golden. You want dark brown.
4. Check for doneness. The internal temperature should read 205-210F (96-99C) on an instant-read thermometer. If it sounds hollow when you tap the bottom and the crust feels hard like a shell, it's done. When in doubt, give it 5 more minutes. GF bread is more forgiving at high temps than it is when underbaked.

Tip: This is the hardest part: don't cut it. GF bread needs at least 2 hours to cool completely. The crumb is still setting as it cools. Cut too early and you'll get a gummy, dense interior that has nothing to do with how you baked it.

Cool Completely Before Slicing

Not optional. GF bread's crumb sets during cooling — the psyllium gel needs time to stabilize. Cutting early is the number one mistake GF bakers make.

1. Remove from Dutch oven. Lift the loaf out of the Dutch oven using the parchment sling. Place on a wire rack immediately — don't leave it sitting in the pot or the bottom will steam and go soft.
2. Cool for 2 hours minimum. Leave the loaf undisturbed on the wire rack for at least 2 hours. If you can wait until the next day, the flavor will be noticeably better and the crumb will be cleaner to slice.

Wait: PT2H

Shape the Boule

GF dough is more forgiving than you'd think for shaping. The psyllium keeps it cohesive enough to handle.

Boule (Round) (recommended)

The best shape for GF bread in a Dutch oven — even steam distribution, great crust development.

1. Oil your surface. Work on a lightly oiled surface rather than a floured one — GF dough doesn't benefit from extra flour the way wheat dough does.
2. Fold and rotate. Pull the edges toward the center in 6-8 folds, rotating the dough between each fold. You're building cohesion, not tension.
3. Flip and smooth. Flip seam-side down and use cupped hands to tighten the surface as best you can. Transfer immediately to the banneton.

Batard (Oval)

Works in an oval Dutch oven. Same folding technique, just elongate rather than round.

1. Fold into a log. Fold the dough over itself lengthwise twice to build an oval shape.
2. Transfer seam-side up. Place in a floured oval banneton seam-side up to proof.

Proof test: Gently press the edge of the dough with a floured fingertip. It should spring back slowly, leaving a slight indent. If it springs back immediately, it needs more time. If it doesn't spring back at all, bake it immediately.

Bake in a Dutch Oven

The Dutch oven method is essential here — it replicates the steam injection of a professional deck oven and gives GF bread the open crust it needs.

Oven: 245°C / 475°F. Internal temperature when done: 96-99°C / 205-210°F.

Dutch Oven — RECOMMENDED (recommended)

Best results by far. Creates the steam environment that gives GF bread a real crust.

Equipment: 4-5.5 quart Dutch oven with lid

1. Preheat 45+ minutes. Dutch oven in the oven from a cold start. 475F (245C). Minimum 45 minutes.
2. Covered 20 minutes. Load the scored boule. Bake covered at 475F (245C) for 20 minutes.
3. Uncovered 30-35 minutes. Remove lid. Reduce to 450F (230C). Bake until internal temp hits 205-210F (96-99C) and crust is deep brown.

Baking Sheet with Steam Pan

Works in a pinch, but the crust won't develop as well without the enclosed environment.

Equipment: Baking sheet, metal roasting pan for steam

1. Create a steam environment. Place a metal pan on the bottom rack during preheat. Add 1 cup of boiling water to the pan when you load the bread.
2. Bake at 450F (230C). Bake for 50-60 minutes until internal temperature reaches 205-210F (96-99C). Cover loosely with foil if browning too fast.

Note: GF bread can handle dark color. The deep brown crust is your friend — it adds flavor and signals that the interior has enough time to set properly.

Storage

• Room temperature: 2-3 days wrapped in a clean kitchen towel or paper bag. Avoid plastic — it traps moisture and softens the crust.
• Refrigerated: Not recommended. Refrigeration stales GF bread faster than wheat bread.
• Frozen: Up to 3 months. Slice the entire loaf before freezing. Pull individual slices directly from the freezer to the toaster.
• Refresh: Warm slices at 350F (175C) for 8-10 minutes to revive the crust, or toast directly from frozen.

Frequently Asked Questions

Can I use a different GF flour blend instead of teff, millet, and sorghum?

You can experiment, but the teff-millet-sorghum combination is specifically chosen for flavor and structure. Rice flour blends will produce a blander loaf with a gummier texture. If you can't find teff, increase the millet and sorghum equally to fill the weight. Don't skip the tapioca starch — it lightens the crumb.

My bread came out gummy inside. What went wrong?

Three possibilities: you underbaked it (internal temp below 205F / 96C), you cut it too soon (needs 2 hours minimum to cool), or your psyllium husk measurement was off. GF gumminess is almost always a baking time or cooling issue, not a recipe problem. Give it more time in the oven and more time on the rack.

Can I skip the overnight sponge?

You can, but the bread will taste noticeably flatter. Increase the instant yeast in the final dough to 7g (about 2 teaspoons) if you go same-day, and add all the sorghum flour to the final dough instead. You'll lose the fermentation flavor but the structure will still work.

Can I use psyllium husk powder instead of whole husks?

Yes, but reduce the amount to 15g (about 2 tablespoons) since powder is more concentrated. The texture will be slightly different — a bit tighter crumb — but it works. Don't use xanthan gum as a substitute; it produces a dense, gummy loaf.

The dough didn't rise much during proofing. Is that normal?

GF dough won't double the way wheat dough does. A 40-60% rise over 1 to 1.5 hours is exactly right. If you're seeing no rise at all after 2 hours, your yeast may be dead or your kitchen may be too cold (below 65F / 18C). Move it somewhere warmer — near a warm oven or in the oven with just the light on.

Does this bread toast well?

It toasts exceptionally well — possibly better than fresh. GF bread often reaches its best texture after toasting because the heat drives off residual moisture and crisps the crumb. If you find the texture a little dense fresh, try it toasted first before making any changes to the recipe.
