Gluten-Free Vegan Sourdough Bread, No Yeast or Xanthan Gum

Why this loaf works

• No commercial yeast – the loaf is naturally leavened with a gluten-free sourdough starter, allowing slow, stable rise and flavor development.
• No xanthan gum – ground flax acts as the primary binder for structure and sliceability; psyllium is optional for extra elasticity.
• No added oils – this recipe keeps fats out of the batter for a cleaner, whole-food loaf.
• Sprouted whole-grain flours – they add flavor, fiber and nutrients; sprouting can improve digestibility and mineral availability.
• Sliceable crumb – the batter-like dough bakes tall in a high-wall loaf tin so you get neat, even slices suitable for toasting.

How to make this gluten‑free sourdough bread

Step 1 — Wake the starter

You need 1 cup of active starter. Feed it with about 1/2 cup brown rice flour and 1/2 cup filtered water, then rest it in a warm spot until bubbly (3–5 hours, depending on temperature). If your starter is thin, reduce the added water; if thick, add a little more.

Step 2 — Mix a thick batter (no kneading)

• When the starter is bubbly, add the sifted flours, ground flax, salt, the rest of the water (about 1½ cups) and maple syrup (optional) in the same bowl.
• Mix until you have a thick, scoopable batter—think thick oatmeal or brownie batter. No kneading is required.

Step 3 — Pan and proof

• Scrape the batter into a high‑wall loaf tin, smooth the top with a wet spatula to form a dome, and add seeds or nuts if desired.
• Cover loosely to retain moisture and proof in a warm spot until the loaf is noticeably domed—about 4–5 hours depending on room temperature.

Step 4 — Bake

• Preheat the oven to 425°F (220°C).
• Uncover and tent the loaf with foil (without touching the batter). Reduce the oven to 390°F (200°C) and bake 30 minutes.
• Remove the foil and, if using parchment, take the loaf out of the tin to allow even browning. Bake another 40–45 minutes until golden.
• Cool completely before slicing—ideally slice the next day with a serrated knife for best results.

Pro tips for baking gluten‑free sourdough bread

• Flour balance: use a mix rather than a single flour—about 70% medium density flours (buckwheat, millet, oat), 10% coarser flours (teff, quinoa, amaranth) and 20% soft/fine flours (finely milled oat or rice) for a balanced crumb and less crumbling.
• Use finely milled flours if you want a finer, more cohesive slice.
• More starter = faster rise: increase the active starter slightly to speed fermentation or proof at a cooler temperature.
• Tang control: a shorter proof gives milder flavor; a longer one produces more sourness.
• Do not disturb the dough once it has risen and is ready to bake—jostling will collapse the loaf.

How to store

Slice and keep at room temperature for 3–4 days in a breathable bag. For longer storage, freeze slices flat in bags and toast from frozen. Re-toasting gives excellent texture and aroma.

Gluten‑Free Sourdough Bread (Vegan, No Yeast, No Xanthan, No Psyllium)

Ingredients

Activate the starter

• 1 cup active gluten‑free sourdough starter (~240 g)
• 1/2 cup brown rice flour (80 g), to revive starter
• 1/2 cup filtered water (approx. 118 ml), adjust as needed

Main batter (add to the active starter)

• 1 cup light buckwheat flour (120 g)
• 1 cup millet flour (120 g) — or 100 g oat flour or 120 g sorghum
• 1/3 cup ground flax seeds (37 g)
• 1½ cups filtered water (355 ml) or plant milk
• 1½ tsp pink salt (or ¾ tsp sea salt)

Optional

• 1 tbsp maple syrup (15 ml) for flavor and faster rise

Instructions

Wake the starter

1. Scoop 1 cup of your refrigerated starter. Feed with 1/2 cup brown rice flour and 1/2 cup water. Cover and leave in a warm spot 3–5 hours until light and bubbly. Feed and refrigerate any remaining starter.

Add the rest and mix

1. When the starter is active, add sifted flours, ground flax, salt, water and maple (if using) in the same bowl.
2. Mix to a thick, scoopable batter—no kneading required.

Pan and proof

1. Scrape batter into a high‑wall loaf tin, smooth the top, add seeds if desired. Cover to retain moisture and proof until domed (about 4–5 hours depending on temperature).

Bake

1. Preheat oven to 425°F (220°C). Uncover, tent with foil (not touching the batter), reduce to 390°F (200°C) and bake 30 minutes.
2. Remove foil and bake 40–45 more minutes until golden brown. Cool completely before slicing; best sliced the next day.

Notes

• Do not shake or touch the dough once it has risen; it will collapse if disturbed.
• For a lighter crumb, use hulled light buckwheat and lighter flours like oat or sorghum.
• If you want extra elasticity, add 1 tbsp psyllium husk mixed with 3 tbsp water (optional).
• Switch flours gradually and only once your starter has been healthy and fed for at least a week.
