Guar gum is a fiber-rich thickening agent derived from guar beans. While technically a carbohydrate, it contributes negligible net carbs when used in small amounts and is commonly used in low-carb, keto, and diabetic-friendly recipes.

How to Use Guar Gum

Guar gum is a highly effective thickener and binder made from guar beans. It can be used to thicken sauces, soups, gravies, dressings, smoothies, and other foods without flour or cornstarch. Only a small amount is usually needed.

Using Guar Gum as a Thickener

Start with about 1/8 teaspoon of guar gum per cup of liquid for light thickening. Whisk or blend thoroughly, then allow the mixture a few minutes to thicken before adding more. Increase the amount gradually if a thicker consistency is needed.

Guar gum works in both hot and cold liquids, making it especially useful for salad dressings, smoothies, cold sauces, and other recipes that are not heated. It can also be used in warm sauces, soups, and gravies.

Preventing Clumps

Sprinkle guar gum gradually over the liquid while whisking continuously rather than adding it all at once. A blender or immersion blender can help distribute the powder evenly in cold mixtures. Adding too much too quickly can create lumps or an overly gummy texture.

Using Guar Gum in Low-Carb Baking

Guar gum can also provide binding and structure in baked goods made with almond flour, coconut flour, and other gluten-free or low-carb flours. It is not a flour substitute and should be used only in small amounts as part of the recipe.

Quick Tip: Start with less guar gum than you think you need. Give it time to fully hydrate before adding more, because an overly thick mixture is much harder to correct than one that needs a little additional thickener.
