What is xanthan gum and what does it do?

Before discussing the best alternatives for this ingredient, it’s essential to understand what it is and its role in the kitchen. Xanthan gum is made by fermenting corn sugar with a bacterium. This is its distinguishing feature compared to other gums like guar or gellan. The bacteria Xanthomonas campestris ferments the glucose in the corn sugar to create the final product.

Despite its name, it is not a gum, so to speak, like chewing gum. Instead, it is a powdered ingredient. Brands like Bob’s Red Mill sell it. Anthony’s, which at one point sold lupin flour, also sells Xanthan gum powder.

You buy it packaged as a powder when you want to use it as an emulsifier and binder. Because of these functions, it’s commonly used in sauces, gravies, soups, stews, baked goods and smoothies. In fact, right now you might have in your refrigerator a salad dressing or another product that already has xanthan gum listed on the ingredients.

Xanthan gum in low-carb cooking

“In my low-carb lifestyle, Xanthan gum is a big part of flour substitution,” says Zuzana Paar of Lowcarb-Nocarb. “I use it as a thickening agent for various recipes. Just a pinch can thicken the sauce into the consistency you have dreamed of. Adding gum into low-carb gnocchi mix allows me to manipulate the dough into perfect shapes with the texture of traditional gnocchi.”

Many of the recipes on this blog feature xanthan gum. That’s because it’s the perfect ingredient for making delicious dishes without adding a lot of carbs or sugar. Some of the recipes that include xanthan gum include:

Lupin Flour Pancakes

Homemade Keto Flour

Broccoli Cheese Soup

The best xanthan gum substitutes

There are quite a few xanthan gum substitutions that you likely have on hand to replace it. If you’re counting carbs, make sure you read the nutrition label for these alternatives to make sure they don’t mess anything up for you. Now onto eight ingredients that you can use as a substitute for xanthan gum.

Cornstarch

Almost everyone has a container of cornstarch in the pantry, making it the most popular substitution for xanthan gum. Since cornstarch is derived from corn, it’s also 100% gluten-free, like xanthan gum. However, check labels, as contamination is possible if the brand doesn’t specifically show a gluten-free certification. Cornstarch is just as effective as xanthan gum as an emulsifier and a thickener and can be used in a 1-to-1 ratio. 

Chia seeds

Chia seeds have long been used in vegan baking as an egg replacer when soaked in water, but the resulting chia gel is also quite helpful as a xanthan gum replacement. Because chia seeds plump up when soaked, creating a texture that might not be pleasant in your final dish, it’s best to grind them first. Add two parts water to one part chia seeds and let the mixture rest for 10 to 15 minutes to form the thickened gel. This gel can then be used in a 1-to-1 ratio for xanthan gum. Ground chia seeds are also great for thickening jams without the need for pectin.

Flax seeds

Like chia seeds, ground flax seeds create a thick paste when combined with water. The seeds must be ground to thicken correctly. Your body also can’t absorb any of the nutrients of the whole seeds, so buying the ground version or doing it yourself at home is a must. Unlike chia seeds, flax gives off a nutty flavor and gritty texture, so bear that in mind when using it as a xanthan gum substitute. Ground flax seeds should follow the same 2-to-1 water-to-seed ratio as chia to thicken. They can be used in a 1-to-1 capacity when swapping out for xanthan gum.

Psyllium husk

This ingredient is popular for its use in digestive aid products. Because it is an insoluble fiber — one that does not break down in the body — the gel-like consistency it forms with water also makes it a great replacement ingredient for xanthan gum. Use psyllium husk in a 2-to-1 ratio for xanthan gum.

“I use a lot of xanthan gum as a gluten-free baker, but I have found that some people cannot process it as well. When I need a xanthan gum substitute, I often turn to psyllium husk,” explains Ksenia Prints of At the Immigrant’s Table. “It binds things together just as well as gum, especially in baked goods that need a lot of structure like bread and pizza, but it’s a lot softer on the stomach.”

Gelatin

Unflavored gelatin is derived from animal collagen and makes an excellent substitute for xanthan gum in baking products like bread and muffins. If the gluten-free flour you’re using doesn’t contain xanthan gum and a recipe calls for it independently, switching to gelatin is an easy swap. You’ll need to use two parts of gelatin for every part of xanthan gum.

Keep in mind that gelatin is animal-derived. Therefore, this substitute is unsuitable for vegetarians or vegans or those who follow a kosher or halal way of eating.

Egg whites

This substitute is even more common in your house than cornstarch, but its uses are a little more specific. Egg whites are best used as a substitute for xanthan gum when the final product is supposed to be light and airy, such as a quick bread or cake. You don’t necessarily want to whisk egg whites into a gravy or soup. One egg white will replace a tablespoon of xanthan gum in a recipe.

Arrowroot starch

Sometimes referred to as arrowroot powder, this starch acts incredibly similar to cornstarch and tapioca starch. Arrowroot comes from the roots of tropical plants, which are dried and ground into a fine powder. This ingredient is popular in gluten-free cooking and among people looking for a more nutritious option to cornstarch. People consider it to be more nutritious because arrowroot has a higher fiber content than cornstarch. If you’re swapping out cornstarch for arrowroot, you’ll want to use twice as much to get the same thickening capacity.

Tapioca starch

Tapioca comes from the root of cassava, a plant native to South America that’s often used to make a creamy mash and also goes by the name yuca. You’ll find tapioca sold in many different forms, including pearls, flour and flakes. However, when it comes to a substitute for xanthan gum, what you want is the starch version. It functions like arrowroot in that you’ll want to use twice as much as cornstarch when thickening liquids.

Where to buy xanthan gum

Most online stores with a gourmet grocery section sell Xanthan gum. Of course, there’s always Amazon where you can find the Anthony’s brand. Even Target sells the Bob’s Red Mill version of xanthan gum.
