Potato flour vs potato starch—what’s the difference? These two potato-based ingredients are commonly confused due to their similar origins, but they serve very different purposes in cooking and baking. In this guide, we’ll break down the differences between potato flour and potato starch, explore their uses, and explain how to substitute one for the other effectively.
What Is Potato Flour?
Potato flour is made from the whole potato, including its skin, and is rich in fiber and nutrients. This flour is often used in gluten-free baking due to its moisture-retaining properties. When comparing potato flour vs potato starch, one of the main differences is the flavor—potato flour has a distinct potato taste, whereas potato starch is flavorless.
How Is Potato Flour Made?
Potato flour production starts by peeling and cooking whole potatoes. Afterward, the potatoes are dried and ground into a powder. Because of this process, potato flour has a slightly coarser texture compared to finer flours such as wheat flour or potato starch. It is this texture, along with the presence of fiber and nutrients, that differentiates potato flour from other starches or flours. Its higher water absorption ability also plays a significant role in baking, helping to keep baked goods moist and tender. This is why it is frequently used in gluten-free baking, where moisture retention is key to achieving the perfect texture.
Uses of Potato Flour in Cooking and Baking
Potato flour is particularly well-suited for gluten-free baking. Its natural moisture-retaining properties help give baked goods a light, fluffy texture, making it an excellent choice for recipes like gluten-free bread, pancakes, waffles, and muffins. Here are some of the best uses of potato flour in cooking and baking:
- Breads and Baked Goods: Potato flour helps give bread a dense, moist structure. It can be used as part of a flour mix for gluten-free bread or in small amounts in regular bread to enhance moisture and texture.
- Thickening Soups and Stews: Although not as common as potato starch for thickening, potato flour can also be used to thicken soups, gravies, and stews, adding a rich, hearty flavor.
- Gluten-Free Recipes: For gluten-free baking, potato flour is commonly mixed with other gluten-free flours like rice flour, almond flour, or tapioca flour to create a blend that mimics the properties of wheat flour.
- Adding Moisture: Potato flour excels at keeping baked goods soft and moist, making it an ideal ingredient in gluten-free pancakes, waffles, and cakes. It helps reduce crumbliness, which is a common issue in gluten-free baking.

What Is Potato Starch?
While potato flour is made from the entire potato, potato starch is derived only from the starchy part of the potato. Potato starch is processed differently, resulting in a fine white powder that is neutral in flavor and contains no fiber or protein. It is commonly used as a thickening agent in both savory and sweet dishes and has the unique advantage of being flavorless, which means it won’t alter the taste of your food.
How Is Potato Starch Made?
Potato starch is produced by crushing raw potatoes to release the starch granules. These granules are then washed, refined, and dried to form a fine, powdery starch. The process removes all fiber, protein, and other nutrients, leaving behind pure starch. This is why potato starch looks and behaves differently from potato flour. Since potato starch is flavorless, it’s often used in delicate recipes where you don’t want the potato flavor to interfere, such as in sauces, gravies, and pastry creams.
Uses of Potato Starch in Cooking and Baking
Potato starch is highly versatile, acting as a thickener, texturizer, and frying agent. Here are some common uses of potato starch:
- Thickening Soups, Sauces, and Gravies: Potato starch is a powerful thickener that works similarly to cornstarch or arrowroot powder. It’s ideal for recipes where a clear sauce or liquid is desired, as it does not cloud the liquid as other starches might. Add it toward the end of the cooking process to prevent it from breaking down under prolonged heat.
- Gluten-Free Baking: Like potato flour, potato starch is also used in gluten-free baking. However, its role is slightly different. Potato starch is often added to lighten the texture of baked goods, making them less dense.
- Frying: One of the most popular uses of potato starch is in frying, where it is used to create a crispy coating. Its high heat tolerance makes it ideal for fried chicken, tempura, and other crispy fried foods. The result is a light, crispy texture that isn’t overly greasy.
- Binding Agent: Potato starch acts as a binding agent in recipes such as meatballs or veggie patties, helping the ingredients stick together without overpowering the taste.

- Both Are Gluten-Free: Since both ingredients come from potatoes, they are naturally gluten-free. This makes them ideal for gluten-free cooking and baking.
- Both Are Used in Gluten-Free Baking: Although their roles in gluten-free baking differ, both potato flour and potato starch are valuable ingredients in gluten-free recipes. Potato flour helps retain moisture and add structure, while potato starch lightens the texture and adds crispiness.
- Both Are Binding Agents: In different contexts, both ingredients can serve as binding agents. Potato starch is often used in meat or veggie patties to hold ingredients together, while potato flour can act similarly in certain baked goods.
Potato Flour in Baking
When baking with potato flour, you can achieve incredible results, particularly in gluten-free recipes. Potato flour’s ability to absorb water makes it perfect for ensuring that gluten-free breads and cakes don’t turn out dry and crumbly.
1. Moisture Retention
Potato flour absorbs and retains moisture, making it one of the most reliable gluten-free flours for baked goods like bread, pancakes, and waffles. In recipes for dense baked goods such as banana bread or carrot cake, potato flour can be used alongside other gluten-free flours to create a moist crumb that doesn’t dry out quickly.
2. Adding Structure to Baked Goods
Gluten-free baking often results in baked goods that are prone to crumbling because gluten is the protein that provides structure. Potato flour helps to fill this gap by creating a stable structure, so your cakes and breads hold together better.
3. Tips for Using Potato Flour in Baking
When using potato flour in your baking, remember that it is highly absorbent, so a little goes a long way. It’s best used in combination with other gluten-free flours such as rice flour or almond flour. Use it sparingly, as too much can make your baked goods heavy and dense. Typically, you would use about ¼ to ½ cup of potato flour for every 2 to 3 cups of gluten-free flour blend.
Potato Starch in Cooking
While potato flour excels in baking, potato starch shines in cooking. It’s a powerful thickener and can elevate the texture of your dishes, from soups and sauces to fried foods.
1. Thickening Soups, Sauces, and Gravies
Potato starch is a go-to thickener for sauces, gravies, and soups. Unlike other thickeners such as flour or cornstarch, potato starch thickens liquids without making them cloudy, which is especially beneficial for clear soups or sauces that need to maintain a bright, clean appearance. When using potato starch to thicken liquids, dissolve it in cold water before adding it to the hot liquid. This prevents clumping and ensures even thickening.
2. Frying and Crisping
One of the best uses of potato starch is frying. Its high heat tolerance allows it to create a crispy, light coating that doesn’t burn easily. Whether you’re making tempura, fried chicken, or even crispy vegetables, potato starch delivers a crunch that’s hard to beat. Simply dredge your ingredients in potato starch before frying for a perfectly crispy coating.
