Psyllium husk is a natural soluble fiber derived from the seeds of Plantago ovata, a plant native to India. It is highly valued in gluten-free baking, particularly for making yeast breads and pizza crusts. When mixed with water, psyllium husk absorbs up to ten times its weight in liquid, hydrating into a thick, mucilaginous gel. This gel provides the binding strength, elasticity, and gas-retention properties that gluten-free grains lack. Unlike xanthan gum, which can make bread crumbs gummy and wet, psyllium husk yields a structured, chewy, and open crumb that closely mimics the texture of traditional wheat bread, allowing gluten-free dough to be kneaded and shaped by hand.

Psyllium husk is available as whole husks or ground powder. Ground psyllium powder is much more concentrated than whole husks when substituting, use about 30% less powder by weight to prevent the dough from drying out and cracking.

Common mistake

Substituting ground psyllium powder 1:1 by volume for whole psyllium husks. The powder is much denser, which absorbs too much water and turns the bread dough dry, dense, and clay-like.

US vs UK / Metric

Sold in health food stores and baking aisles. Ensure you purchase unflavored, unsweetened psyllium, as sweetened varieties will alter recipe flavor.

When to use it

Best for making gluten-free yeast breads, pizza crusts, and flatbreads that require stretch, chewiness, and hand-shaping.

Substitution

Replace 1 tablespoon of xanthan gum with 2 tablespoons of ground psyllium husk mixed with liquid.

Storage tip

Keep in a cool, dark pantry in a sealed container for up to 1 year to prevent the fiber from absorbing ambient moisture.
