Cornstarch, that ubiquitous white powder lurking in the back of many pantries, is a kitchen staple for thickening sauces, soups, gravies, and desserts. But what happens when you run out, are looking for a healthier alternative, or simply can’t use it due to dietary restrictions like a corn allergy? Fear not! A plethora of substitutes exist, each with its own unique properties and ideal applications. Let’s explore the best cornstarch alternatives and how to use them effectively.
Understanding Cornstarch and Its Thickening Properties
Before diving into the substitutes, it’s crucial to understand what makes cornstarch such a good thickener. Cornstarch is pure starch derived from corn kernels. When heated in liquid, the starch granules absorb the liquid and swell, causing the mixture to thicken. This process is known as gelatinization. Cornstarch provides a clear, glossy finish and doesn’t significantly alter the flavor of the dish. It’s also relatively inexpensive and readily available, making it a popular choice. However, it’s important to remember that cornstarch can clump if not mixed properly with cold liquid before adding it to a hot dish. Also, it’s not stable in acidic environments or when exposed to prolonged high heat, which can cause it to break down and lose its thickening power.
Top Cornstarch Alternatives: A Comprehensive Overview
Now, let’s explore the various alternatives to cornstarch, examining their properties, thickening power, and ideal uses.
Wheat Flour: A Pantry Staple
Wheat flour, a common ingredient in most kitchens, can be used as a thickener, although it requires a slightly different approach than cornstarch. Wheat flour contains gluten, which needs to be cooked out to avoid a starchy taste.
To use wheat flour as a thickener, create a roux by cooking it with butter or oil over medium heat. The roux helps to prevent clumping and provides a smoother texture. The ratio is typically equal parts flour and fat. Cook the roux for a few minutes, depending on the desired color and flavor. A lighter roux is ideal for white sauces, while a darker roux adds a nutty flavor to brown sauces. Whisk the roux into the liquid you want to thicken, ensuring there are no lumps. Simmer the mixture until it reaches the desired consistency. Keep in mind that wheat flour isn’t as potent a thickener as cornstarch, so you’ll typically need to use twice as much flour as you would cornstarch. Wheat flour will also add a slightly opaque, rather than glossy, finish to your dish.
Potato Starch: A Powerful Thickener
Potato starch, derived from potatoes, is a potent thickener that’s gluten-free. It has a higher thickening power than cornstarch, so you’ll need to use less.
Like cornstarch, potato starch should be mixed with cold water before adding it to a hot liquid to prevent clumping. Potato starch provides a clear, glossy finish, similar to cornstarch. However, it’s important to avoid overheating potato starch, as it can break down and lose its thickening power if cooked for too long or at too high a temperature. It’s best added towards the end of cooking. Potato starch is an excellent choice for thickening sauces, soups, and gravies, particularly when you want a clear, glossy finish. It’s also a good option for those with corn allergies.
Tapioca Starch: A Versatile Gluten-Free Option
Tapioca starch, also known as tapioca flour, is derived from the cassava root. It’s a gluten-free and versatile thickener that’s widely used in both savory and sweet dishes. Tapioca starch provides a slightly chewy texture, which can be desirable in some applications, such as pie fillings.
To use tapioca starch, mix it with cold water before adding it to the hot liquid. Tapioca starch thickens at a lower temperature than cornstarch, so it’s important to monitor the mixture closely to prevent over-thickening. Tapioca starch is a good choice for thickening fruit fillings, sauces, and soups. It’s also often used in gluten-free baking to improve the texture of baked goods. While it yields a glossy finish, it can sometimes leave a slightly gluey texture if overused.
Rice Flour: A Mild-Flavored Choice
Rice flour, made from finely milled rice, is another gluten-free alternative to cornstarch. It has a mild flavor that doesn’t significantly alter the taste of the dish. Rice flour provides a slightly opaque finish and is best suited for thickening sauces and soups where a clear finish isn’t essential.
There are two main types of rice flour: white rice flour and brown rice flour. White rice flour has a more neutral flavor and is a better choice for thickening. Brown rice flour has a nuttier flavor and may impart a slightly grainy texture. To use rice flour, mix it with cold water before adding it to the hot liquid. Rice flour doesn’t thicken as much as cornstarch, so you may need to use more to achieve the desired consistency. It’s a good option for thickening Asian-inspired sauces and soups.
Arrowroot Powder: A Healthier and Neutral Option
Arrowroot powder, derived from the arrowroot plant, is a natural and gluten-free thickener. It’s known for its ability to create a clear, glossy finish and its neutral flavor, making it a versatile substitute for cornstarch.
Arrowroot powder is also easily digestible and contains various minerals, making it a potentially healthier choice. To use arrowroot powder, mix it with cold water before adding it to the hot liquid. Arrowroot powder thickens at a lower temperature than cornstarch and should be added towards the end of cooking. It’s important to avoid overheating arrowroot powder, as it can break down and lose its thickening power if cooked for too long or at too high a temperature. Arrowroot powder is a good choice for thickening sauces, soups, gravies, and fruit fillings. It’s also a popular choice for making clear glazes and sauces.
Glucomannan: A Keto-Friendly Option
Glucomannan is a soluble fiber derived from the konjac root. It’s a very potent thickener and requires only a small amount to achieve the desired consistency. It’s also low in carbohydrates, making it a popular choice for those following a keto or low-carb diet.
Glucomannan doesn’t add any flavor to the dish and creates a clear, gel-like texture. To use glucomannan, mix it with cold water and then add it to the hot liquid. It’s important to add glucomannan gradually, as it thickens very quickly. Start with a small amount and add more until you reach the desired consistency. Glucomannan is a good choice for thickening soups, sauces, and stews. It can also be used to make sugar-free jellies and desserts.
Xanthan Gum: A Powerful and Versatile Option
Xanthan gum is a polysaccharide produced by bacterial fermentation. It’s a powerful thickener and stabilizer that’s commonly used in gluten-free baking and cooking.
Xanthan gum is very effective at thickening liquids and preventing separation. It can be used in both hot and cold applications and is stable over a wide range of temperatures and pH levels. To use xanthan gum, mix it with the dry ingredients before adding the liquid. This helps to prevent clumping. Use a very small amount of xanthan gum, as it’s very potent. Start with a pinch and add more until you reach the desired consistency. Xanthan gum is a good choice for thickening sauces, soups, dressings, and baked goods. It’s also often used to improve the texture and shelf life of gluten-free products.
Chia Seeds: A Nutritious and Natural Thickener
Chia seeds are small, nutrient-rich seeds that are known for their ability to absorb liquid and form a gel. They’re a good source of fiber, omega-3 fatty acids, and antioxidants, making them a healthy and natural way to thicken liquids.
When chia seeds are soaked in liquid, they swell and form a gel-like consistency. This gel can be used to thicken smoothies, soups, sauces, and puddings. To use chia seeds as a thickener, simply add them to the liquid and let them soak for at least 30 minutes, or until they have formed a gel. The amount of chia seeds you need will depend on the desired thickness. Start with a small amount and add more until you reach the desired consistency. Chia seeds will add a slightly nutty flavor and a slightly textured consistency to your dish.
Flaxseed Meal: Another Nutritious Option
Similar to chia seeds, flaxseed meal can also be used as a thickening agent. Flaxseed meal, made from ground flax seeds, also possesses gelling properties when mixed with liquid.
Flaxseed is a good source of fiber and omega-3 fatty acids. When flaxseed meal is combined with water, it forms a slurry that can add viscosity to a recipe. It is often used in vegan baking as an egg replacement, and this same property can be utilized for thickening sauces or soups. It will impart a slightly nutty flavor, and like chia seeds, might leave a slightly grainy texture. Start with a small amount, about a tablespoon, per cup of liquid and allow it to sit for a few minutes to gel before adding more.
Pureed Vegetables: A Healthy and Flavorful Option
Pureed vegetables can be used to thicken soups, sauces, and stews while adding flavor and nutrients. Vegetables like potatoes, carrots, butternut squash, and cauliflower are excellent choices for thickening.
To use pureed vegetables, simply cook the vegetables until they are soft and then puree them using a blender or food processor. Add the pureed vegetables to the liquid you want to thicken and stir until well combined. The amount of pureed vegetables you need will depend on the desired thickness and the flavor of the vegetables. Pureed vegetables will add a slightly different flavor to your dish, so choose vegetables that complement the other ingredients.

What is the best overall substitute for cornstarch for thickening sauces?
The “best” overall substitute depends on the specific recipe and desired outcome. However, potato starch is often considered a close alternative. It offers a similar thickening power to cornstarch, resulting in a clear, glossy sauce. It’s especially suitable for sauces, gravies, and stews where you want a neutral flavor and avoid a cloudy appearance.
Potato starch must be mixed with cold liquid before adding it to the hot mixture to prevent clumping. Also, keep in mind that potato starch can become gummy if overcooked or exposed to high heat for too long. Therefore, add it gradually and avoid prolonged simmering.
Can I use flour as a cornstarch substitute, and if so, what are the considerations?
Yes, all-purpose flour can be used as a cornstarch substitute, but it has some distinct differences. Flour has less thickening power than cornstarch, so you’ll typically need to use about twice as much flour as cornstarch to achieve the same thickness. The sauce may also have a slightly different texture, potentially being a bit more opaque and less glossy.
Before adding flour to hot liquids, it’s crucial to create a roux by cooking it with butter or oil first, or mix it thoroughly with cold water to form a slurry. This step prevents the flour from clumping and ensures even distribution in the sauce. Cook the sauce for a longer time than you would with cornstarch to ensure the flour is cooked through and the starchy flavor is eliminated.
How does tapioca starch compare to cornstarch for thickening desserts?
Tapioca starch is an excellent option for thickening desserts, particularly fruit pies and sauces. Like cornstarch, it provides a relatively clear, glossy finish. However, tapioca starch can be a bit stringy or gummy if used in excessive amounts.
For the best results, use quick-cooking tapioca instead of tapioca flour for thickening pies. Tapioca pearls need time to absorb the liquid, so it’s better for pies and desserts that bake for extended periods. Be cautious not to overcook tapioca starch, as it can lose its thickening power and result in a runny dessert.
What’s the best way to use arrowroot powder as a thickening agent?
Arrowroot powder is another viable alternative to cornstarch, known for its ability to create a clear, glossy sauce. It is a good option for those with corn allergies or sensitivities. Arrowroot is best suited for sauces, fruit glazes, and light desserts.
Always mix arrowroot powder with cold water before adding it to hot liquids, and add it towards the end of cooking. Avoid boiling arrowroot, as this can break down its thickening properties and result in a thin, watery sauce. Be gentle and stir frequently to avoid lumps.
Is rice flour a suitable substitute for cornstarch, especially for gluten-free recipes?
Rice flour is indeed a suitable substitute for cornstarch, especially when preparing gluten-free recipes. It offers a neutral flavor and can effectively thicken sauces, soups, and gravies. It provides a slightly less glossy finish compared to cornstarch but remains a reliable option.
When using rice flour, it’s important to mix it with cold water or broth to create a slurry before adding it to the hot liquid. This prevents clumping. Also, it often requires slightly more rice flour than cornstarch to achieve the same level of thickness.
How does using gelatin as a thickening agent differ from using cornstarch?
Gelatin provides a significantly different thickening mechanism compared to cornstarch. Cornstarch thickens through the swelling of starch granules when heated, while gelatin thickens through the formation of a protein network as it cools. Gelatin sets liquids into a solid or semi-solid state rather than just thickening them.
Gelatin is commonly used in desserts like jellies, mousses, and panna cotta. It requires blooming in cold water before being dissolved in hot liquid, and then chilling to set. It doesn’t work in hot dishes like gravies or sauces, where cornstarch is preferred. It’s also important to consider that gelatin is derived from animal collagen.
When might I choose xanthan gum as a thickening agent over cornstarch?
Xanthan gum is frequently used in gluten-free baking and for thickening cold sauces, dressings, and smoothies. Its thickening power is potent, and a small amount can create a significant difference in viscosity. It’s especially valuable when dealing with low-fat or low-sugar recipes where cornstarch might not perform optimally.
Unlike cornstarch, xanthan gum doesn’t require heat to activate its thickening properties. However, it’s crucial to use it sparingly, as too much can result in a slimy or gummy texture. To prevent clumping, mix xanthan gum with a dry ingredient like sugar or flour before incorporating it into the liquid.
