Have you ever been in the middle of a recipe and realized you're out of xanthan gum? Or perhaps you're seeking a more natural, gluten-free alternative? Don't worry-many people have been there! Whether you're baking soft, fluffy gluten-free bread or thickening a creamy keto-friendly sauce, finding the right xanthan gum substitute is key to achieving the perfect texture. This article provides a comprehensive guide to xanthan gum substitutes, especially for those following a keto or gluten-free lifestyle.
What is Xanthan Gum?
Xanthan gum is a widely used thickener and stabilizer in various food products, from gluten-free baked goods to keto-friendly sauces. It is a plant-based additive produced by fermenting corn sugar with a natural bacteria called Xanthomonas campestris. This fermentation process results in a gum that can prevent ice crystal formation and improve the texture of various foods. Xanthan gum easily dissolves in hot or cold water, producing a viscous solution.
Why is Xanthan Gum Used?
Xanthan gum is valued for its ability to:
- Act as a thickening agent.
- Bind ingredients together.
- Emulsify substances that would otherwise remain separate, such as oil and vinegar.
- Stabilize mixtures.
These properties make it a popular ingredient in salad dressings, baked goods (especially gluten-free items), and various other food products.
Xanthan Gum and the Keto Diet
For those following a low-carb, ketogenic lifestyle, xanthan gum can be a valuable ingredient. It has zero net carbs and is very low in calories, with only 30 calories in a 9-gram (2 tablespoons) serving. Additionally, it contains no fat or protein.

Benefits of Xanthan Gum on Keto
- Keeps daily carbs low: Xanthan gum doesn't add carbs to your meals due to its zero net carb content.
- Increases fiber intake: A 2-tablespoon serving provides 7 grams of fiber.
- May lower cholesterol: Some studies suggest that daily consumption of xanthan gum may result in a moderate reduction in serum cholesterol.
- Helps control blood sugar levels: Xanthan gum and psyllium husk are soluble fibers, which your digestive tract can’t break down. Instead, they form a gel-like substance and help slow absorption.
Potential Drawbacks of Xanthan Gum
Despite its benefits, some individuals may prefer to avoid xanthan gum due to allergies, digestive issues, or a desire for more natural alternatives. Consuming large doses of xanthan gum (e.g., 15 grams) may lead to digestive problems such as gas, bloating, more frequent bowel movements, softer stools, and diarrhea. Individuals taking diabetes medication should also exercise caution and consume only small amounts of xanthan gum, as it can affect blood sugar levels.
Finding the Right Xanthan Gum Substitute
Fortunately, several substitutes can replicate xanthan gum's thickening and stabilizing properties. The best choice depends on the specific application, whether it's baking, sauce-making, or creating dairy-free recipes.
General Tips for Substituting Xanthan Gum
- Consider the specific properties needed for your recipe (thickening, binding, emulsifying).
- Start with small amounts and adjust as needed to achieve the desired consistency.
- Be mindful of the potential flavor impact of the substitute on the final product.
- Remember that some substitutes work better in certain applications than others.
Top Xanthan Gum Substitutes
1. Psyllium Husk
Psyllium husk is derived from the husks of Plantago ovata seeds and is available in ground form for baking. Like xanthan gum, it is a soluble fiber that forms a gel-like substance in the gut, making it an excellent substitute. Psyllium husk may also help lower blood sugar levels.
- Ratio: Use 2 parts of psyllium husk for every 1 part of xanthan gum.
2. Chia Seeds
Chia seeds form a gel when soaked in liquid, similar to xanthan gum. They are also rich in fiber and essential nutrients. While chia seeds can be used whole, grinding them will result in a smoother texture.
- Ratio: Replace xanthan gum with chia seeds in a 1:1 ratio.
- Preparation: Add 2 parts of hot water for every 1 part of chia seeds and stir until the mixture becomes viscous.
- Note: Using chia gel may require increasing baking time by 10-15 minutes.
3. Flax Seeds
Like chia seeds, flax seeds create a thick paste when mixed with water. It is important to use ground flax seed (flax meal) for optimal binding. Ground flax seeds may impart a slightly nutty and gritty texture to the recipe.

- Ratio: Use ground flax seeds in a 1:1 ratio with xanthan gum.
- Preparation: Mix with 2 parts of hot water for every 1 part of flax.
4. Cornstarch
Cornstarch has a texture similar to xanthan gum and is highly absorbent, making it a good thickener for stews and gravies. Ensure the cornstarch is certified gluten-free if you are avoiding gluten.
- Ratio: Replace xanthan gum with the same amount of cornstarch (1:1 ratio).
- Note: No need to mix with water before use.
5. Gelatin
Gelatin, derived from animal collagen, helps firm up dishes and is an excellent choice for baked goods like breads and muffins. However, it is not suitable for vegans, vegetarians, or those following kosher or halal dietary practices.
- Ratio: Use 2 parts of gelatin for every 1 part of xanthan gum.
6. Egg Whites
Egg whites act as both leavening and binding agents, making them a suitable substitute for xanthan gum in quick breads, batter breads, and cakes. They create a light and fluffy texture but are not ideal for kneaded breads.
- Ratio: Use 1 egg white to replace every tablespoon (4.5 grams) of xanthan gum.
- Note: Not vegan-friendly.
7. Agar Agar
Agar agar, derived from red algae, acts much like a vegan form of gelatin. It is available as flakes, sheets, or powder.
- Ratio: Replace xanthan gum with agar agar in a 1:1 ratio.
- Preparation: Dissolve agar agar in room-temperature water (4 tablespoons of water for every 1 tablespoon of flakes or 1 teaspoon of powder). Heat over low heat for 3-5 minutes until dissolved, then cool slightly before use.
- Note: May produce a slightly stiffer or denser texture.
8. Guar Gum
Guar gum, derived from guar beans, functions similarly to xanthan gum as a binder and thickener.

- Ratio: Use 3 parts of guar gum for every 2 parts of xanthan gum.
- Tip: Blend guar gum with the oils in your dish first, then add the mixture to the rest of the liquids.
- Note: Guar gum works best in cold foods like salad dressings and is even more powerful as a thickener than xanthan gum.
9. Konjac Powder
Konjac powder, also known as glucomannan, is made from konjac root and is commonly used in Asian cooking. Its high fiber content helps thicken dishes similarly to xanthan gum.
- Ratio: Swap konjac powder for xanthan gum in a 1:1 ratio for most baked goods. When making chewier foods like tortillas or flatbreads, use 1.5 times the amount of guar gum.
Applications of Xanthan Gum and Its Substitutes
Gluten-Free Baking
In gluten-free baking, xanthan gum (or its substitutes) is essential for holding ingredients together and improving texture. Gluten provides elasticity and structure in traditional baked goods, which is lacking in gluten-free recipes.
Sauces and Dressings
Xanthan gum and its alternatives are used to thicken sauces, dressings, and soups, providing a smooth and creamy consistency.
Keto-Friendly Recipes
For those on a keto diet, xanthan gum and certain substitutes can help create low-carb versions of favorite dishes, such as cheesecakes, energy balls, and fried chicken.
Practical Tips for Using Xanthan Gum and Its Substitutes
- Thickening Liquids: To thicken liquids like sauces, condiments, soups, or creams, sprinkle a small amount of xanthan gum or a suitable substitute and blend until completely mixed.
- Gluten-Free Fried Chicken: Coat chicken with a mixture of low-carb flours (almond flour and coconut flour), paprika, and xanthan gum (or a substitute) for a crispy, gluten-free coating.
- Improving Drink Texture: Add xanthan gum or a substitute to protein shakes, smoothies, coffee, and cocktails to make them thicker and creamier.
