12 Best Agar Agar Substitutes 

While we can all agree that no ingredient is irreplaceable, you may want to change the recipe to meet your dietary needs or to alter the texture and composition of the final dish.

So if you find yourself in the kitchen with no agar agar in sight, here are some of the alternatives currently available on the market: 

1. Gelatin 

For the first substitute on our list, we have chosen a classic ingredient that can commonly be found in jello and other dessert products.

While gelatin is considered to be one of the best thickening agents in the world, it does come with the setback of being an animal-based product, which means it is unsuitable for vegetarians.

In a similar fashion to agar agar, gelatin is a tasteless and odorless substance, which means it won’t affect the flavor of your final dish. 

In fact, gelatin is an easier substance to work with than agar agar and comes with the advantage of being available in most grocery stores across the country. While both products have similar characteristics, gelatin-based products will have to be kept in the refrigerator to maintain their shape and solidity.

When it comes to nutritional value, gelatin is known to be less nutritious than agar agar, as it is commonly made from fatty animal products. Beyond this, agar agar will commonly need to be boiled during the cooking process, whereas gelatin can be used as it is. If you want to use gelatin in your recipes, you will need to substitute the agar agar with a 3:1 ratio. 

How To Substitute

Substitute gelatin with agar agar to create gummies, candies, or other desserts. The substitution of gelatin with agar agar is popular in Asian cuisine. It can be used as a sauce or filling for cakes and pastries.

2. Pectin Powder 

If you are a passionate vegetarian and need a plant-based substitute for agar agar, then you can use a product called pectin powder. Unlike agar agar, pectin is made from an assortment of berries and citrus fruits, which makes it the ideal ingredient when making homemade jellies and jams.

Not only can the substance be used in a similar way to agar agar, but it can also be used to develop the structure and composition of your preserves. 

However, pectin powder does contain a high percentage of fiber and does not come with any nutritional benefits for the consumer. Beyond this, pectin powder also contains natural sugars, which limits it to the preparation of sweet dishes. So if you want to use your substitute for savory recipes, then pectin may not be the best choice.

Fortunately, it follows the same rule of thumb as agar agar, which means you will only need to use a 3:1 ratio when making your delicious treats. 

How To Substitute

You can substitute pectin powder with agar agar in order to create a healthy vegan jelly. It is a type of seaweed used as a thickener that comes in a variety of forms, including powder, flakes, and granules, jams and jellies.

3. Xanthan Gum 

The next substitute on our list is a relative newcomer to the culinary world, which means it can be very difficult to find at your local store.

However, this does not mean that it should be overlooked, as it remains one of the best thickening agents currently available on the market. Made from fermented bacteria, xanthan gum can be used in a range of delicious dishes and comes with similar thickening properties as agar agar. 

When using this substance, you will need to use a 1:1 ratio, as this will produce the best results for you and your finished product. The only downside to using xanthan gum is that it can be very expensive, although this can sometimes be worth it due to its accessible nature and long shelf life.  

How To Substitute

Xanthan gum is a thickening agent that is found in a wide variety of foods, including dressings, sauces, and yogurts. It is also used in cosmetics and shampoos.

4. Guar Gum 

Guar gum is a natural thickening agent that is commonly derived from guar beans, which makes it gluten-free and an ideal substitute for agar agar.

Because of its versatile nature, the product is primarily used as an alternative to wheat flour, although this does not mean it is limited to certain dishes, as it can be used in a variety of different bakes. 

Beyond this, the product is considered a nutritious and healthy substance, which means it is suitable for health enthusiasts and dietary restrictions.

Guar gum can commonly be used when making pizza dough, cakes, muffins and other baked goods. However, when using guar gum, it is important to use the correct measurements, as too much of the ingredient could ruin the final product. 

For the best results, we recommend only using half a tablespoon per cup, especially when using it as a substitute in complex recipes. 

How To Substitute

You can easily substitute guar gum with agar agar as guar gum is a sugar-free chewing gum that comes in various flavors, including mint, cherry, cinnamon, and peppermint. The gum is sold in single sticks, which come in flavors like lemon, grapefruit, and cola.

5. Carrageenan 

Another popular substitute for agar agar is carrageenan, which is another plant-based product. Unlike agar agar, carrageenan is a polysaccharide, which means it can commonly be found in desserts, beer, soy milk and a selection of processed meats. 

However, carrageenan provides no nutritional value and comes with no discernible flavor, so it can be used as a thickening agent as well as a stabilizer. For this reason, you can use carrageenan as a substitute for agar agar without running into any problems. 

How To Substitute

Unlike agar agar, you can substitute it with Carrageenan. It is a natural polymer extracted from red seaweed that is commonly used as a thickening and gelling agent. It can be used to thicken and stabilize foods like salad dressings, sauces, and jellies.

6. Cornstarch

Capable of being used in a variety of different dishes, cornstarch can be used as an effective alternative to agar agar, as the flavorless substance exhibits similar properties and is capable of thickening various mixtures. 

These days, cornstarch is commonly used as an anti-cake agent, with the product also being found in cookies and an array of desserts. In most cases, cornstarch can be used to provide a tenderness to an otherwise unsatisfying dish, making it the perfect ingredient for home cooks. 

When it comes to using cornstarch, we recommend that you substitute the agar agar with one tablespoon, which equals a ratio of 1:1. 

How To Substitute

Cornstarch is a fine powder made from corn, with uses ranging from thickening gravies to mixing with paints. It is a key ingredient in gluten-free cooking, especially when combined with xanthan gum.

7. Konnyaku Or Konjac

Konnyaku is a jelly-like substance that is commonly found in Asian cuisine. It is a popular ingredient in some jello recipes.

Konnyaku is a good substitute for agar in a recipe. Konnyaku has a firm texture and can be cooked, but it is also commonly used in recipes that require no cooking, like gelatin.

It works great as a substitute for agar with a more bouncy jelly texture that would make your recipe the thickness it requires.

Use it in a 1:1 ratio for the best result. However, if you cook for children, you should not use them as they are considered choking agents and are banned in many countries.

8. Arrowroot Powder

A substitute for agar is arrowroot powder, also known as arrowroot starch. Arrowroot powder works extremely well in place of agar in a wide variety of dishes, and it has a neutral flavor similar to that of cornstarch.

Arrowroot Powder is a gluten-free, non-GMO, vegan substitute for agar in any recipe. It can make vegan jelly, sorbet, and other gel-like desserts.

How To Substitute

9. Unflavored Gelatin

Agar needs to be heated to dissolve and gel properly, so follow the recipe instructions for heating the agar before adding it to your mixture.

Once the agar has been heated, you may use it in the recipe the same way you would add gelatin.

Unflavored gelatin is the most accessible substitute for the agar. Replace the agar in your recipe with the same amount of unflavored gelatin.
