Unlock the secrets of oat flour: can it replace cornstarch as a thickener?

Cornstarch, a common thickening agent, is often used in various culinary applications. However, for individuals with gluten intolerance or those seeking healthier alternatives, finding a suitable substitute becomes essential. Enter oat flour, a nutritious and versatile ingredient that has gained popularity as a potential replacement for cornstarch. This blog post will delve into the question of whether oat flour can indeed serve as an effective substitute for cornstarch, exploring their similarities, differences, and practical applications.

Similarities Between Oat Flour and Cornstarch

1. Thickening Properties: Both oat flour and cornstarch possess thickening properties, making them suitable for thickening sauces, gravies, and other liquids.

2. Neutral Flavor: Both ingredients have a neutral flavor, ensuring they do not alter the taste of dishes.

Differences Between Oat Flour and Cornstarch

1. Nutritional Value: Oat flour is significantly more nutritious than cornstarch, providing fiber, protein, and essential vitamins and minerals. Cornstarch, on the other hand, is primarily composed of carbohydrates.

2. Texture: Oat flour imparts a slightly gritty texture to dishes, while cornstarch produces a smoother, more transparent finish.

Applications of Oat Flour as a Cornstarch Substitute

Oat flour can be used in various applications where cornstarch is traditionally employed, including:

• Thickening Sauces and Gravies: Replace cornstarch with an equal amount of oat flour to thicken sauces and gravies. For example, in a recipe calling for 2 tablespoons of cornstarch, use 2 tablespoons of oat flour.

• Coating for Frying: Oat flour can be used as a coating for frying, providing a crispy and flavorful exterior.

• Baking: Oat flour can be incorporated into baking recipes as a thickening agent and to add nutritional value.

How to Use Oat Flour as a Cornstarch Substitute

1. Use a Smaller Amount: Oat flour has a stronger thickening power than cornstarch, so use approximately 2/3 to 3/4 of the amount of cornstarch called for in the recipe.

2. Mix with Liquid First: To prevent clumping, mix oat flour with a small amount of liquid before adding it to the main mixture.

3. Cook Thoroughly: Oat flour requires more cooking time than cornstarch to fully thicken. Allow sauces and gravies to simmer for a few minutes after adding oat flour.
