Substitute for Xanthan Gum: 5 Best Alternatives for Gluten-Free Baking
Best Substitute
Psyllium Husk Powder
2 tsp psyllium husk powder per 1 tsp xanthan gum
Creates a gel when mixed with water that mimics gluten's stretch. Best substitute for gluten-free bread where structure and chew are critical. Research from the University of Milan confirmed it enhances gluten-free dough properties.
Flavor & Texture Change
Neutral flavor. No noticeable taste difference in finished baked goods.
When Not to Use
Must be mixed with water before adding to dry ingredients. Can make batter gummy if too much is used. Darker color may tint light-colored baked goods slightly.

Which Xanthan Gum Substitute Should You Use?
Best for GF Bread
Psyllium Husk Powder
Creates stretch and chew closest to gluten. Backed by food science research.
Best for Sauces
Guar Gum
Strong thickening power in both cold and hot applications. Most direct swap.
Best Whole-Food
Ground Flaxseed + Water
No specialty ingredients needed. Gels naturally when mixed with water.
All Alternatives
Guar Gum
1½ tsp guar gum per 1 tsp xanthan gum
The most common direct substitute. Made from guar beans with strong thickening power. Works well in both cold and hot applications.
Flavor/texture:Neutral flavor. Slightly less elastic than xanthan gum in dough but produces similar results in most recipes.
Avoid when:Not as good at retaining moisture in yeast breads baked at high temperatures for long periods. Can clump if not dispersed properly in liquid. Use slightly more than xanthan gum.

Chia Seeds (ground)
1 tsp ground chia seeds + 2 tsp hot water per 1 tsp xanthan gum
Mix ground chia seeds with hot water and let sit until a gel forms. The gel acts as a binder in baked goods. May need 10-15 extra minutes of baking time.
Flavor/texture:Mild, slightly nutty flavor. May add subtle crunch from seed particles.
Avoid when:Visible specks in light-colored baked goods. Creates a slightly different texture than xanthan gum. Not suitable for clear sauces or dressings.

Ground Flaxseed + Water
1 tsp ground flaxseed + 2 tsp warm water per 1 tsp xanthan gum
Mix ground flaxseed with warm water and let sit 5 minutes until gelled. Works as a binder in baked goods, similar to a flax egg.
Flavor/texture:Noticeable nutty, earthy flavor. Works best in recipes with strong flavors like chocolate, banana, or spice that mask the flax taste.
Avoid when:Adds a slightly nutty, earthy flavor and brown color. Not suitable for light-colored or delicately flavored baked goods. Can make textures slightly gummy.

Egg Whites
1 egg white per 1 tsp xanthan gum
Whipped egg whites act as an excellent binder, preventing dry and crumbly textures in gluten-free baking. Already present in many recipes.
Flavor/texture:Neutral flavor. Adds structure and lift. Can make baked goods slightly more airy and cake-like.
Avoid when:Not vegan. Changes the protein content and may alter the crumb structure. Not suitable for thickening sauces or dressings.

Tips
Xanthan gum serves two main roles: binding in gluten-free baking and thickening in sauces. Choose your substitute based on which role you need. For binding, psyllium husk and guar gum are best. For thickening, guar gum and cornstarch work well. A little goes a long way with all substitutes.
How to Substitute Xanthan Gum
A plant-based thickener and stabilizer made by fermenting corn sugar. Used in gluten-free baking to mimic gluten's binding and stretching properties, and in sauces, dressings, and ice cream for thickening.
The best substitute for xanthan gum depends on what role it plays in your recipe. Our top recommendation is Psyllium Husk Powder (2 tsp psyllium husk powder per 1 tsp xanthan gum), which works well for gluten-free bread, pizza dough, yeast baking.
If you need a different option, Guar Gum (1½ tsp guar gum per 1 tsp xanthan gum) is another reliable choice. The most common direct substitute. Made from guar beans with strong thickening power. Works well in both cold and hot applications.
When substituting xanthan gum, consider the flavor profile, texture, and cooking method of your recipe. For vegan alternatives, look for the options marked with the vegan badge above.

Frequently Asked Questions
What can I use instead of xanthan gum in gluten-free baking?
Psyllium husk powder is the best substitute. Use 2 teaspoons per 1 teaspoon of xanthan gum. It creates a gel that mimics gluten's stretch, especially in bread recipes.
Can I use cornstarch instead of xanthan gum?
Cornstarch works as a thickener in sauces and gravies but does not provide the binding that xanthan gum gives in baking. For thickening, use 1 tablespoon cornstarch per 1 teaspoon xanthan gum.
Is guar gum the same as xanthan gum?
They are similar but not identical. Both are thickeners and binders, but guar gum is made from guar beans while xanthan gum is made by fermenting corn sugar. Use 1.5 teaspoons guar gum per 1 teaspoon xanthan gum.
