Agar agar is a gelling agent derived from red algae, used mainly in vegan recipes to replace gelatin.

It’s fairly easy to find now, but if you don’t have it on hand for a recipe, there are a few alternatives.

The 3 Closest Plant-Based Substitutes for Agar Agar

You can substitute any of the following ingredients in a 1:1 ratio (e.g. 1 tbsp of either gum for 1 tbsp of agar agar):

They won’t give you quite the same “jelly” texture as agar agar, but will thicken up your food.

I’d recommend looking for the first 2 options first, as carrageenan  is usually harder to find.

If you’re desperate, there’s 1 final option: starch. Either corn starch or tapioca starch can do in a pinch. They are both used to thicken up liquids (like in vegan heavy cream substitutes).

It’s a bit more time consuming of a substitution though.

How to Substitute Corn or Tapioca Starch for Agar Agar

tapioca starch

Note that tapioca starch also goes by the name of “tapioca powder.”

Start with a 2:1 ratio, so 2 tbsp of corn or tapioca starch for each tbsp of agar agar flakes or powder.

Then, mix it with water in a 1:1 ratio. For example, 2 tbsp of cornstarch should be whisked together with 2 tbsp of water. Then add it to your recipe.

If your recipe isn’t thickening up enough, add more starch to it.
