13 Handy Cornstarch Alternatives

Updated by Louise Cutler on August 19, 2025

Just like any other kitchen staple, having a reliable cornstarch substitute on hand can be a lifesaver when you’re in the middle of cooking and realize you’ve run out. If you find yourself in this predicament, take heart – there are some excellent alternatives that you might already have in your pantry.

What Is Corn Starch?

Fundamentally, cornflour – also known as corn starch – is a carbohydrate derived from the corn grain. The starch is obtained from the endosperm of the kernel, making it a crucial component of the grain’s nutritional profile. While it comes in the form of a white powder and has a high caloric content with limited nutritional value, there are alternatives available for those seeking healthier options.

Interestingly, cornstarch is made entirely from corn and is gluten-free, rendering it an essential pantry staple for individuals with dietary restrictions or preferences.

What Is Cornstarch Used For?

While an essential ingredient in many recipes, cornstarch is commonly employed worldwide in cooking and baking to achieve a desired consistency. It serves as a thickening agent, stabilizing various foods across the globe – from sauces and gravies to glazes, soups, and any other dish that requires its unique properties.

Cornstarch Substitutes

Rice Flour

Rice Flour

When it comes to understanding the basics of rice flour, one thing becomes immediately apparent: its incredibly fine texture. Derived from ground rice, this flour has become a staple for those seeking gluten-free alternatives to traditional wheat flour. With its impressive nutritional profile boasting more protein and fiber compared to cornstarch, using rice flour as a replacement can be a significantly healthier choice.

Its versatility is also noteworthy, particularly in Asian cuisine where it’s often employed to thicken soups, noodles, and sweet treats. A further benefit lies in its neutral color when mixed with water, making it ideal for enhancing the clarity of clear liquids. In terms of proportions, it’s generally advised to use roughly double the amount of rice flour compared to cornstarch to achieve the desired consistency.

Potato Starch

Potato Starch

Harnessing the power of potato starch, a versatile and widely used ingredient in cooking, has become increasingly popular due to its ease of use and effective thickening properties. Made from the process of crushing potatoes to release their starch content, which is then dried into a powder with a flour-like consistency, it’s no wonder why it’s a staple in many kitchens.

This starch can be used to thicken soups, gravies, pie fillings, sauces, and stews as it effectively absorbs water, making it an ideal thickening agent. However, it’s essential to note that the starch can break down in extreme heat, which means that it may not absorb moisture properly and perform its intended function. To achieve optimal results, heat the starch gently and add it gradually to any sauces.

Additionally, as potato starch is naturally gluten-free, it often serves as a popular gluten-free alternative to traditional flours, making it an excellent choice for those with dietary restrictions or preferences.

All-Purpose Flour

All-Purpose Flour

Replacing all-purpose flour with cornstarch is a viable option when you’re cooking and the most likely ingredient that you’ll have available. It’s also cost-effective and easy to find in most kitchens, making it a popular substitute. When substituting all-purpose flour for cornstarch, it’s essential to follow a two-to-one ratio, meaning that for every one cup of cornstarch called for in the recipe, use two cups of flour.

This means you’ll need to use more flour as it doesn’t have the same thickening properties as cornstarch. When using it in a sauce or liquid-based mixture, add the flour gradually and at intervals, monitoring its consistency to avoid an overly thickened texture.

Arrowroot Powder

Arrowroot Powder

Little known outside of culinary circles, arrowroot powder is a versatile ingredient that offers several benefits for those looking for natural alternatives in their cooking. Sourced from the roots of the Maranta genus of plants, typically found in tropical regions, this starchy flour has been gaining popularity among health-conscious cooks and bakers.

In its production process, the roots are dried and ground into an extremely fine powder, which can then be used as a thickening agent or replacement for traditional flours.

As a bonus, this natural ingredient is also gluten-free, making it an excellent substitute for traditional flours in recipes, especially for those with dietary restrictions.

Xanthan Gum

Xanthan Gum

Among its many applications, Xanthan Gum is a versatile food additive that has gained popularity due to its unique properties as a thickening agent and food stabilizer. Derived from sugar, this powder can come from various sources such as wheat, corn, soy, and dairy, making it a widely available ingredient. The sugar is fermented with a specific bacteria called Xanthomonas campestris, resulting in the production of xanthan gum.

Its ability to thicken large quantities of fluids makes it an ideal addition to various products, including bottled salad dressings, where it helps keep solid particles in suspension. In addition to thickening, xanthan gum can also be used as a replacement for gluten in gluten-free baking, replicating the sticky effect that gluten creates in doughs. Furthermore, its stabilizing properties make it an essential ingredient in non-dairy products such as ice creams, sauces, and milk.

When using xanthan gum in recipes, it is crucial to note that only small amounts are needed, which should be added slowly to avoid over-thickening the mixture. If excessive amounts of xanthan gum are used, the dish or liquid may become slimy in texture, affecting its overall quality.

Tapioca Flour

Tapioca Flour

Highlighting its unique characteristics, tapioca flour is not actually made from tapioca plants, but rather cassava roots that are extracted and dried to remove their starchy liquid. Hailing from South America, the cassava root vegetable has become a versatile ingredient in various culinary applications.

This flavorless flour boasts impressive thickening properties, making it an ideal substitute for other starches like potato starch and arrowroot powder, particularly in homemade puddings, cookie dough, sauces, and gravies. Notably, tapioca flour outperforms these alternatives in terms of its thickening ability. Furthermore, as a naturally gluten-free ingredient, it can be easily integrated into gluten-free cooking, available in various forms such as flour, pearls, and flakes.

Additionally, individuals with diabetes or prediabetes may benefit from using tapioca flour due to its lower glycemic index compared to wheat flour. The recommended substitution ratio is one tablespoon of cornstarch for every two tablespoons of tapioca flour.

Wheat Flour

Wheat Flour

Sprouting from the whole wheat kernel comes wheat flour, which is often referred to as whole wheat flour due to its comprehensive origin. Utilizing the entire kernel in the grinding process results in a flour that exhibits a darker hue and a nuttier flavor profile compared to all-purpose flour. One of the primary advantages of using whole wheat flour is its significantly higher nutrient and fiber content than its all-purpose counterpart.

It’s essential to note that before substituting wheat flour for cornstarch, it must be blended with cold water to create a paste, thereby preventing clumps from forming. Generally speaking, you’ll need to use roughly twice as much wheat flour compared to an equivalent amount of cornstarch to achieve the desired thickness in mixtures. The distinct flavor imparted by wheat flour is often characterized as ‘earthy’ and robust, setting it apart from the neutral taste of cornstarch.

Glucomannan

Glucomannan

Fiber-rich Glucomannan, derived from the konjac plant or elephant yam, has been an integral part of Asian cultures’ food and medicine for centuries. Its versatility lies in its ability to bulk up foods without adding calories or carbohydrates, making it a popular ingredient in diet foods such as pasta and noodles. Additionally, Glucomannan’s probiotic properties help nourish the gut with healthy bacteria, contributing to a balanced digestive system.

Research suggests that incorporating Glucomannan into one’s diet can lead to a 10% decrease in bad cholesterol levels. However, its unique consistency, more gel-like than powdery, limits its use as a breadcrumb substitute for deep-frying purposes. To achieve optimal results, mix Glucomannan with cold water, as it thickens best at low temperatures. A general guideline is to use a quarter of a teaspoon of Glucomannan for every two teaspoons of cornstarch.

Ground Flaxseeds
