1. Arrowroot powder

Arrowroot powder is a type of starch produced from the tubers of arrowroot plants. The same as the cornstarch, this powder is perfect for gluten-free cooking. It’s also used as a thickening agent in soups, puddings, and sauces.

So the next time you’ve run short of potato starch, open your cupboard and look for arrowroot powder. As a substitute, use two teaspoons of arrowroot starch for every one tablespoon of potato starch. 

  • Ratio: Use two teaspoons of arrowroot powder for every one tablespoon of potato starch.

3. Tapioca starch

Another good replacement for potato starch is tapioca starch. This type of starch is gluten-free flour made from the starch of cassava root. These roots are dried and pounded until it becomes fine-textured flour. Many for its thick and chewy texture, tapioca starch is loved by many for sauces, soups, and stews. It also has a slightly sweet flavor, making it suitable for baked goods. As a substitute, use one-fourth cup of tapioca starch for every two cups of potato starch

  • Usage: Best for sauces, soups, stews, and baked goods due to its thick, chewy texture.

4. Potato flour

If you think potato flour and potato starch are the same, you’re wrong! When it comes to taste, potato starch has a neutral flavor profile while potato flour features that potato-like flavor variation. The former is gluten-free and provides a glossy finish to any dish.

It has no flavor with a light texture.Plus, this flour is so versatile that it works well with other ingredients. For best results, add rice flour at the beginning of your cooking process and let them cook at a slow pace.As a substitute, use the ratio of 1:1.

It’s my least favorite substitute but if it’s your only option double the required amount.

  • Usage: Can be used in baking but is not as effective for thickening.
