Gluten-free bread can stay dense, collapse after baking or feel gummy even when the recipe looks correct. The reason is simple: without gluten, the dough needs a different balance of flour, starch, binder, water, yeast and technique.
Why gluten-free bread behaves differently
In wheat bread, gluten forms an elastic network that traps fermentation gases. Gluten-free dough must create that structure with starches and binders. It usually looks more like a thick batter than a firm kneadable dough.
10 common mistakes and practical fixes
1. Using only one flour
A single rice, maize or buckwheat flour rarely provides the ideal structure. Combine wholegrain flour with a starch such as tapioca, potato or maize starch for a lighter crumb.
2. Skipping the binder or using the wrong amount
Psyllium husk and xanthan gum help hold gas and moisture. Too little can cause crumbling; too much may create a gummy texture. Follow a tested formula and weigh the ingredient accurately.
3. Inactive yeast
Old yeast or yeast exposed to excessive heat may not work. Check the expiry date and, when the recipe requires it, test the yeast in lukewarm liquid with a small amount of sugar.
4. Water that is too hot or too cold
Very hot water can damage yeast, while cold water slows fermentation. Use comfortably lukewarm liquid unless the yeast manufacturer states otherwise.
5. Low hydration
Gluten-free flours and especially psyllium absorb significant water. A dry, stiff mixture cannot expand well. The correct dough is often soft and sticky.
6. Treating it like wheat dough
Adding extra flour until the dough stops sticking usually makes gluten-free bread dense. Mix thoroughly to hydrate the ingredients, but do not expect a traditional wheat-dough texture.
7. Incorrect proofing time
Under-proofed bread remains tight; over-proofed bread may rise and then collapse. Bake when the dough has visibly expanded and appears aerated, not simply after a fixed number of minutes.
8. Using the wrong pan size
A pan that is too wide spreads the dough and produces a low loaf. Choose the pan size specified by the recipe and avoid filling it too high.
9. Baking in an oven that is not fully preheated
The first minutes of baking set the structure. Preheat the oven completely and avoid opening the door early.
10. Cutting the loaf while hot
The crumb continues to set as it cools. Cutting too early releases steam and can make the centre look wet or compressed.
Quick troubleshooting table
| Problem | Likely cause | What to try |
|---|---|---|
| Dense loaf | Low hydration or inactive yeast | Check yeast and increase water only within the recipe’s tested range |
| Loaf rises then collapses | Over-proofing or excess liquid | Shorten proofing and weigh liquids accurately |
| Dry, crumbly crumb | Insufficient binder or moisture | Use the specified psyllium or xanthan and avoid excess flour |
| Gummy centre | Under-baking, excess binder or early slicing | Check internal doneness and cool fully |
Psyllium or xanthan gum?
Both can improve gluten-free bread, but they do not always replace each other gram for gram. Psyllium often adds elasticity and moisture retention; xanthan can strengthen batter-like doughs. Use the binder chosen for the original formula.

Frequently asked questions
Should gluten-free bread dough be sticky?
Usually yes. Many successful gluten-free bread doughs resemble a thick batter and are much softer than wheat dough.
Can I add more yeast to make it rise?
More yeast is not always the solution and may create an unpleasant flavour or unstable rise. First check hydration, binder, temperature and proofing time.
Why does my loaf sink after leaving the oven?
Common causes include over-proofing, too much liquid, insufficient baking or a structure too weak to hold the gases.
How long should I wait before slicing?
Let the loaf cool completely on a rack. The exact time depends on loaf size, but the centre should no longer feel warm.
