The 5 Best Substitutes for Agar Agar

If you're looking for a Vegan, Paleo, or gluten-free version of gelatin, agar agar is a great option.

But what if you can't find it or don't have any on hand? Here are five substitutes for agar agar that you can use in a pinch.

1 - Cornstarch

cornstarch Save for Later!

Cornstarch is a fine, powdery starch made from corn.

It's used as a thickening agent in everything from sauces and gravies to pie fillings and puddings.

When combined with liquid, cornstarch becomes a gel-like substance that can help thicken, bind, and stabilize food.

Cornstarch can be used as a 1:1 replacement for agar agar in most recipes.

To substitute, simply mix cornstarch with an equal amount of cold water until smooth.

Then add it to your recipe in the same way you would add agar agar.

Keep in mind that cornstarch won't be set as firm as agar agar, so you may need to use more of it to achieve the desired consistency.

You can also find pre-mixed cornstarch and water mixtures (called "slurry") at some Asian markets.

2 - Cassava Flour

cassava flour Save for Later!

Cassava flour is a type of flour made from the root of the cassava plant.

It is a staple ingredient in many parts of South America, Africa, and Asia.

Cassava flour has a light, slightly sweet flavor and a dense, starchy texture.

It can be used in many recipes, including bread, cakes, cookies, and pies.

Cassava flour can also be used as a Thickener for soups and sauces.

Cassava flour can be substituted for agar agar in a 1:1 ratio.

When substituting cassava flour for agar agar, it is important to simmer the mixture for longer than you would with agar agar powder to ensure the cassava flour is fully cooked.

Cassava flour can also be used as a thickener for soups and sauces.

When using cassava flour as a thickener, it is important to add it slowly to the soup or sauce while constantly whisking to avoid lumps.

3 - Xanthan Gum

xanthan gum Save for Later!

Xanthan gum is a food additive that is used to thicken or stabilize foods.

It is made from a type of bacteria called Xanthomonas campestris, which is found in plants.

Xanthan gum has a variety of uses, including in baking, as a thickener for sauces and soups, and as an emulsifier for salad dressings and ice cream.

It can also be used to create gluten-free recipes.

In baking, xanthan gum helps bind ingredients together and structure doughs and batters.

When substituting xanthan gum for agar agar, use the same amount of xanthan gum as you would agar agar.

Xanthan gum can be purchased at most grocery stores or online.

4 - Tapioca Flour

Tapioca flour is a gluten-free, grain-free flour made from cassava root.

It's a starchy flour with a mild flavor and slightly sticky texture.

It's often used as a thickener in the impersonation of cornstarch.

Tapioca flour can be used to thicken sauces, soups, and pudding.

It can also be used in baking to add moistness and texture to gluten-free baked goods.

Tapioca flour is also a good substitute for arrowroot powder.

When substituting tapioca flour for agar agar, use the same amount of tapioca flour as you would agar agar.

To use tapioca flour:

  • Combine tapioca flour with an equal amount of cold water or other liquid.
  • Stir until the tapioca flour is completely dissolved.
  • Add the liquid mixture to your recipe, and cook as directed.
  • Remember that the longer you cook tapioca flour, the more gelatinous it will become. If you're looking for a less gelatinous consistency, cook for a shorter period.

5 - Arrowroot Powder

arrowroot powder Save for Later!

Arrowroot powder is a starch extracted from the root of the plant Maranta arundinacea.

Arrowroot powder can be used as a thickening agent in recipes such as sauces, puddings, and pie fillings.

It has a neutral flavor and will not alter the taste of your dish.

Arrowroot powder can also be used as a replacement for agar agar.

To use arrowroot powder as a thickening agent, mix it with cold water before adding it to your recipe.

This will help to prevent lumps from forming.

You can also substitute arrowroot powder for cornstarch in a 1:1 ratio.

You can find arrowroot powder in the baking aisle of most grocery stores.

Frequently Asked Questions

What is the best substitute for Top Agar Agar?

Cornstarch, Cassava Flour, Xanthan Gum, Tapioca Flour, and Arrowroot Powder. Use it at a 1:1 ratio in any recipe that calls for Top Agar Agar.

What can I use if I run out?

Yes, and the results are often hard to tell apart. Cornstarch is the go-to replacement.

Can you combine two substitutes for a closer match?

Sometimes. Blending two partial substitutes - one for flavor and one for texture - gets closer to the original.

This works best when neither alone fully replicates what you need.

Can the substitute be used raw as well as cooked?

Not always. Some substitutes are processed or have a strong raw flavor that disappears with heat.

Check whether the original is typically used raw before assuming the substitute will work the same way.
