The 5 Best Substitutes for Agar Agar

Have you ever wondered what gives Jell-O its jiggle? Or how to make homemade marshmallows?

If so, then you’ve likely encountered agar agar.

This vegan-friendly gelatin is made from red algae and is commonly used in Asian cuisine.

It’s also gaining popularity as a healthy alternative to traditional gelatin.

If you’re curious about this versatile ingredient, read on to learn everything you need to know about agar agar, including how to cook with it and the best substitutes for it.

What is Agar Agar?

Agar agar is made from the dried and processed seaweed known as Gelidium amansii.

This red algae grows in cool, shallow waters along the coastlines of Japan, Korea, and China.

To make agar agar, the seaweed is boiled until it forms a gel, then dried and ground into a powder.

The powder can then be used to create a variety of textures in both sweet and savory dishes.

Agar agar has several interesting properties – it’s odorless and tasteless, and it can absorb up to 200 times its weight in water.

When added to liquids, it will quickly thicken and solidify at room temperature.

And unlike gelatin, which must be cooled before eating, dishes made with agar agar can be eaten hot or cold.

Agar agar is a great option if you’re looking for a vegetarian or vegan alternative to gelatin.

It can be used to make everything from jelly desserts to savory pies.

And because it comes in powder and flake form, it’s easy to use in almost any recipe.

Just keep in mind that you’ll need to use more agar agar than gelatin – about twice as much – to achieve the same texture.

Not sure where to start? Here are five delicious recipes that feature agar agar:

  • Strawberry Agar Agar Jello: This pretty pink jello is made with fresh strawberries and coconut milk for a light and refreshing dessert.
  • Chocolate Pudding: This vegan chocolate pudding is thickened with agar agar instead of eggs or cornstarch. It’s rich, creamy, and totally delicious.
  • Lime Cheesecake: This no-bake cheesecake gets its firm texture from agar agar instead of gelatin. It’s perfect for summer entertaining.
  • Strawberry Ice Cream: This homemade strawberry ice cream uses frozen strawberries and an Agar Agar-based churning method for a smooth and creamy treat. No ice cream maker is required.
  • Vegan Quiche: This quiche uses tofu combined with vegetables and seasonings for a hearty brunch or dinner dish. Agar Agar helps give it the traditional quiche texture without using eggs.

The next time you’re in the mood for something sweet or savory, give one of these agar agar recipes a try.

You might just be surprised at how versatile this ingredient can be.

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 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

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

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

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

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.


In conclusion, agar agar is a great way to thicken, emulsify, and stabilize recipes.

However, it’s not always easy to find or work with.

If you’re in a pinch, any of the five substitutes listed above should work well in most recipes.

Just keep in mind that each one will affect the flavor and texture of your dish in some way.

So, be sure to experiment until you find the perfect replacement for your needs.
