9 Excellent Alternatives to Potato Starch

1. Cornstarch

Cornstarch is a tried-and-true thickener and popular gluten-free option. For most recipes, swapping potato starch with cornstarch using a 1:1 ratio works perfectly—especially in soups, sauces, and gravies. It even adds a tender, crumbly texture to baked goods. Just note that it may not hold up as well under very high heat.

2. Tapioca Starch

Also known as tapioca flour, this starch comes from the cassava plant and is a favorite in gluten-free cooking. It excels in thickening pancakes, bread, and even pizza crusts as well as desserts like puddings. When used as a thickener, substitute it equal to potato starch. For baked recipes, however, you might need to boost the amount by 25–50% for ideal results.

3. Arrowroot Powder

Arrowroot powder is nearly flavorless and helps create a smooth, glossy finish in sauces, stews, and jellies. It’s a versatile substitute, though since it is a bit drier than potato starch, use slightly less. A good rule is about 2 teaspoons of arrowroot for each tablespoon of potato starch.

4. Rice Flour

Rice flour is a gluten-free alternative made from finely milled rice. Its mild nature makes it an excellent thickener and a substitute in baked goods. However, it can introduce a slightly gritty texture, so consider using about 2 tablespoons per cup of liquid to achieve the best consistency.

5. Mochiko Flour

Mochiko flour, made from short-grain rice, brings a subtle sweetness and sticky texture to your dishes. It works well as a direct 1:1 replacement for potato starch in sweets like cakes, muffins, and even as a coating for fried foods.

6. Wheat Flour

A kitchen staple, wheat flour is incredibly versatile. It can form a perfect batter for fried dishes and works well in baked recipes. Because it isn’t as refined as potato starch, you might need roughly twice the amount, and remember, it isn't gluten-free.

7. Potato Flour

Unlike potato starch which is purely extracted, potato flour is made from whole, dried potatoes. You can use it in a 1:1 ratio in recipes like breads, pizza crusts, and soups. However, its distinctive earthy flavor makes it better suited for savory dishes.

8. Coconut Flour

A favorite in paleo and keto cooking, coconut flour offers a hint of natural sweetness. It works particularly well in desserts and baked goods. Since coconut flour absorbs more liquid, reduce the amount by about 10–15% when substituting for potato starch.

9. Instant Mashed Potatoes

Instant mashed potatoes, made from cooked and dehydrated potatoes, are a handy substitute. Process them into a finer powder using a food processor, then use them in the same measurement as potato starch to thicken soups, sauces, and gravies.

The Bottom Line

While potato starch is a versatile ingredient ideal for thickening, you have a range of alternatives to choose from when it's not available. Experimenting with these substitutes can lead to exciting culinary discoveries and fresh twists on your favorite dishes.
