Cornstarch is a wonderfully versatile ingredient, used for everything from thickening soups and sauces to creating the perfect texture in baked goods. With this handy list, you’ll always have a quick reference for the best cornstarch alternatives at your fingertips. From savory dishes to sweet oven-baked desserts, we’ve got you covered with effective solutions for every cooking situation.

What Is Cornstarch?

Cornstarch is a fine, powdery substance that is essentially pure starch, extracted from the endosperm of corn kernels. The process involves removing the outer bran and germ, leaving behind the starchy core. This natural origin makes cornstarch inherently gluten-free, making it a popular choice for individuals with dietary restrictions.

Its primary role in the kitchen is as an excellent thickening agent. When mixed with a cold liquid (to create a slurry) and then introduced to a hot liquid, the starch granules absorb water and swell, causing the liquid to thicken rapidly. This property makes it ideal for achieving the desired consistency in gravies, sauces, soups, puddings, pie fillings, and custards. One of cornstarch’s distinct advantages is that it thickens without altering the flavor of your dish and typically produces a clear, glossy finish, which is particularly desirable in fruit pies and clear sauces.

It’s crucial to understand that cornstarch is not the same as corn flour. While both are derived from corn, they are distinct products with different culinary applications. Cornstarch is pure starch, offering superior thickening power and a neutral flavor, making it perfect for slurries. Corn flour, on the other hand, is made from finely ground whole corn kernels, retaining some protein, fiber, and flavor. It behaves more like a traditional flour and will not provide the same transparent, glossy thickening results when combined with tablespoons of water.

Top 10 Cornstarch Substitutes

When you’re in a pinch or simply looking for an alternative, these pantry staples offer reliable thickening solutions. Each has unique properties that make it suitable for different types of dishes.

1. All-Purpose Flour

All-purpose flour is one of the most common and versatile thickening agents you’ll find in nearly every kitchen. It contains starch, protein, and some fiber, allowing it to thicken liquids effectively. For substitution, use a 2:1 ratio of flour to cornstarch. For instance, if a recipe calls for 1 tablespoon of cornstarch, use 2 tablespoons of all-purpose flour.

How to use: To avoid lumps, always create a slurry by mixing the flour with an equal amount of cold water or fat (like butter for a roux) before adding it to your hot liquid. Flour-based thickeners need to cook for several minutes (typically 5-10 minutes) to cook out the raw flour taste and achieve full thickening potential. While it won’t produce the same glossy, transparent finish as cornstarch, it creates a more opaque, creamy texture, making it excellent for gravies, stews, and hearty sauces.

Considerations: All-purpose flour is not gluten-free, so it’s not suitable for those with gluten sensitivities or celiac disease. Its thickening power is less potent than cornstarch, which is why a higher ratio is needed.

2. Almond Flour

Almond flour is a popular gluten-free alternative, finely ground from blanched almonds. While it’s not a pure starch, its protein and fat content can contribute to thickening, especially in baked goods and some sauces. When substituting with almond flour, use a 1:1 ratio. So, if your recipe calls for 2 teaspoons of cornstarch, you would use 2 teaspoons of almond flour.

How to use: Almond flour works best in recipes where a slight nutty flavor is welcome and a very thick consistency isn’t the primary goal. It can absorb moisture, adding body to batters and some sauces. It’s often used in gluten-free baking to provide structure and moisture, but less so as a primary thickening agent for gravies or clear sauces.

Considerations: Due to its protein and fat content, almond flour doesn’t produce the same clear, smooth thickening as cornstarch. It will likely impart a noticeable flavor and a slightly grainy texture. It’s also more expensive than other flour options and not suitable for nut allergies.

3. Arrowroot Powder

Arrowroot powder, derived from the arrowroot plant, is an excellent gluten-free substitute for cornstarch, often preferred for its clear, glossy finish. Use arrowroot powder in a 2:1 ratio for cornstarch; for example, 2 tablespoons of arrowroot for 1 tablespoon of cornstarch.

How to use: Like cornstarch, arrowroot powder should be mixed into a slurry with a cold liquid before being added to your recipe to prevent lumps. It thickens at a lower temperature than cornstarch and tolerates acidic ingredients better without breaking down, making it ideal for fruit sauces, vinaigrettes, and clear broths. However, it’s generally not recommended for dairy-based recipes, as it can create a slightly slimy or ‘silky’ texture that some find undesirable, particularly in pastry cream or custards.

Considerations: Arrowroot can become stringy or lose its thickening power if overcooked, so it’s best to add it towards the end of the cooking process and heat gently until thickened. It also doesn’t hold up well to freezing and thawing, as it can become spongy.

4. Rice Flour

Rice flour, made from finely milled rice, is another fantastic gluten-free alternative to cornstarch, especially valued for its neutral flavor and clear thickening properties. When substituting, use a 2:1 ratio: 2 tablespoons of rice flour for 1 tablespoon of cornstarch.

How to use: Similar to cornstarch and arrowroot, rice flour should first be combined with a small amount of cold liquid to form a smooth slurry before being stirred into your hot liquid. It’s particularly effective for thickening clear liquids, such as Asian sauces, soups, and gravies, producing a relatively transparent finish. It’s also a great option for dusting foods before frying to create a crisp coating.

Considerations: Like other flours, rice flour needs adequate cooking time to fully thicken and for any raw flour taste to dissipate. Its thickening power can be slightly less robust than cornstarch, necessitating the higher substitution ratio.

5. Xanthan Gum

Xanthan gum is a powerful, plant-based hydrocolloid produced by fermenting sugars with the bacterium Xanthomonas campestris. It’s an incredibly potent thickening agent, and it’s essential to remember that a little goes a very long way! Begin with an extremely small amount, perhaps as little as ⅛ or ¼ of the cornstarch amount called for in the recipe.

How to use: Sprinkle xanthan gum slowly and gradually into the liquid while whisking vigorously to prevent clumping. Adding too much too quickly can result in an unpleasantly slimy or gelatinous texture. It’s excellent for gluten-free baking, salad dressings, and as a stabilizer in sauces and gravies, especially when you need a thickener that doesn’t require heat to activate.

Considerations: Its powerful thickening ability means precision is key. Experiment with small amounts and increase gradually until the desired consistency is achieved. It can be expensive, but a single packet lasts a long time due to the minute quantities needed.

6. Potato Starch

Potato starch, extracted from potatoes, is an excellent gluten-free substitute that behaves very similarly to cornstarch. It provides a clear, glossy finish and a smooth texture, making it a reliable choice for many applications. For substitution, use a straightforward 1:1 ratio: if your recipe calls for 1 tablespoon of cornstarch, use 1 tablespoon of potato starch.

How to use: Just like cornstarch, potato starch should be whisked into a cold liquid to create a slurry before being incorporated into hot liquids. It thickens quickly and effectively. It’s particularly good for thickening gravies, soups, and fruit pie fillings, offering a transparent appearance and smooth mouthfeel.

Considerations: Potato starch does not tolerate prolonged high heat or vigorous boiling as well as cornstarch, as it can lose its thickening power. It’s best to add it towards the end of cooking and heat gently until thickened. It also doesn’t hold up as well as tapioca starch in dishes that will be frozen and thawed.

7. Tapioca Flour (Tapioca Starch)

Tapioca flour, also known as tapioca starch, is derived from the cassava root. The root is ground, filtered, and then dried into a fine powder. This gluten-free thickener creates a glossy, slightly chewy texture and is excellent for fruit fillings and baked goods that will be frozen, as it remains stable through thawing.

How to use: When substituting tapioca flour for cornstarch, use a 1:2 ratio. For example, if the recipe calls for 1 tablespoon of cornstarch, use 2 tablespoons of tapioca flour. It can be used in a slurry with cold water, similar to cornstarch, and then added to hot liquids. It works well in pie fillings, puddings, and sauces, providing a lovely sheen and somewhat elastic texture.

Considerations: Tapioca flour can become stringy if over-stirred or over-cooked, so add it at the end of cooking and stir gently until the desired thickness is reached. Its thickening power is slightly less than cornstarch, hence the higher substitution ratio.

8. Guar Gum

Guar gum is another potent hydrocolloid, very similar to xanthan gum in its thickening capabilities but derived from guar beans. It’s often a more economical alternative to xanthan gum, making it a popular choice for many. Like xanthan gum, a little guar gum goes an incredibly long way, so precision is key.

How to use: Begin with very small increments, typically around ¼ teaspoon, and add gradually to your liquid while whisking continuously. This helps prevent clumping and ensures you don’t over-thicken the mixture. Guar gum is particularly effective in cold applications, such as salad dressings, ice cream, and gluten-free baked goods, where it helps with binding and texture.

Considerations: Overuse of guar gum can lead to a gummy or slimy texture, so cautious, gradual addition is essential. It activates quickly and doesn’t require heat to thicken, which can be advantageous in certain recipes.

9. Psyllium Husk

Psyllium husk, derived from the seeds of the Plantago ovata plant, is a soluble fiber that is exceptionally absorbent. It’s a fantastic plant-based, low-carb, and gluten-free substitute for cornstarch, especially popular in keto and low-carb diets. When using psyllium husk as a thickener, start with only about ½ teaspoon in your recipe.

How to use: Psyllium husk expands significantly when it absorbs liquid, so it’s very easy to add more than you need. Sprinkle it slowly into your liquid while whisking, allowing it a few minutes to hydrate and thicken before deciding if more is needed. It’s often used in gluten-free baking to add structure and elasticity, and in smoothies or gravies for thickening.

Considerations: Psyllium husk can impart a slightly earthy flavor and may give a darker hue or a slightly gelatinous, spongy texture to dishes, which might not be desirable in all applications. It’s crucial to increase the amount gradually to achieve the desired consistency without compromising the dish’s texture or appearance.

10. Wheat Flour

Wheat flour, specifically referring to standard whole wheat flour, is another straightforward and common cornstarch substitute, similar in principle to all-purpose flour but with a slightly different composition due to the inclusion of the bran and germ. For substitution, simply use a 1:2 ratio: if the recipe calls for 1 tablespoon of cornstarch, use 2 tablespoons of wheat flour.

How to use: Like all-purpose flour, wheat flour must be made into a slurry with cold water or fat (like butter for a roux) before being added to hot liquids to prevent lumps. It also requires a longer cooking time—typically 5 to 10 minutes of simmering—to fully cook out the raw flour taste and achieve its full thickening potential. It produces an opaque, hearty consistency, making it well-suited for robust gravies, thick sauces, and stews.

Considerations: Wheat flour is not gluten-free and will give a cloudy finish to your sauces rather than a clear, glossy one. Its flavor can be slightly more pronounced than all-purpose flour due to the bran. It’s a reliable emergency substitute but consider its impact on the final color and taste of your dish.

Additional Thickening Techniques

Beyond powdered substitutes, there are other creative ways to thicken your recipes, especially if you prefer to avoid starches or gums altogether. These methods often add flavor and nutrition as well!

• Pureed Vegetables: A fantastic way to thicken soups, stews, chilis, and sauces while boosting their nutritional content and flavor. Simply blend cooked vegetables like potatoes, carrots, pumpkin, squash, or even beans into a smooth puree and stir them into your dish. This creates a rich, creamy texture without any added flour or starch.
• Simmer for an Extended Time (Reduction): One of the oldest and simplest thickening methods involves simply simmering your recipe over low heat for an extended period. As the liquid evaporates, the flavors concentrate, and the sauce or broth naturally thickens. This technique, known as reduction, is perfect for intensifying the taste of sauces and stocks without adding any external ingredients. Just be mindful not to let it burn, and stir occasionally.
