What is a Roux?

A roux is a fundamental component of many classic French and Cajun dishes. It is a mixture made from equal parts of fat, typically butter, and flour. This combination is cooked together over heat until it reaches a desired level of color and thickness. The process of cooking the flour in fat helps to eliminate any raw taste and allows the flour to act as a thickening agent when added to sauces, soups, and stews.

Roux serves as a versatile base for a wide range of dishes, lending them a rich, smooth texture and enhancing their flavors. Its role goes beyond thickening; it also adds a subtle nutty aroma and a depth of flavor that can transform ordinary dishes into culinary delights. Different types of roux are used for various applications, each offering its unique characteristics and uses.

The Basic Roux Ingredients

To create a roux, you will need just two simple ingredients: fat and flour. Here’s a breakdown of each component:


The fat used in a roux provides both flavor and texture to the final dish. The most common choice is unsalted butter due to its rich taste and smooth consistency. However, other fats like vegetable oil, lard, or even bacon fat can be used depending on the desired flavor profile. It’s important to note that the fat should have a relatively high smoke point to prevent burning during the cooking process.


All-purpose flour is the preferred choice for making roux. Its moderate protein content allows for proper thickening without becoming too gummy or lumpy. The flour should be sifted before use to remove any clumps and ensure a smooth mixture. The amount of flour used depends on the desired thickness of the final sauce or dish.

Choosing the Right Fat for Your Roux

The choice of fat in a roux can greatly impact the flavor and texture of the final dish. Different fats bring their unique characteristics to the table. Here are some common options to consider:


Butter is the classic choice for making a roux. It lends a rich, creamy flavor and adds a luxurious velvety texture to sauces and dishes. Unsalted butter is preferred as it allows for better control over the seasoning of the final dish.

Vegetable Oil:

Vegetable oils, such as canola, sunflower, or grapeseed oil, are popular alternatives to butter. They have a higher smoke point, making them suitable for recipes that require higher cooking temperatures. Vegetable oil can result in a lighter and less rich flavor compared to butter, but it still provides a smooth texture to the roux.


Lard, rendered pork fat, is commonly used in traditional Southern and Cajun cuisines. It imparts a distinct savory flavor and richness to the roux. Lard is particularly well-suited for dishes like gumbo and jambalaya, where its flavor complements the overall taste profile.

Bacon Fat:

For a smoky and indulgent twist, bacon fat can be used in a roux. It infuses the dish with a delicious bacon essence, adding depth and complexity to the flavor. Bacon fat is best suited for recipes that benefit from a smoky or savory taste.

Different Types of Roux: White, Blond, and Brown

Roux comes in various shades, each offering distinct flavors and uses in cooking. Let’s explore the three primary types of roux:

White Roux:

White roux, also known as “roux blanc,” is cooked for a short period, just until the raw flour taste disappears. It has a pale, ivory color and a subtle nutty aroma. White roux is typically used in dishes that require thickening without adding much color, such as béchamel sauce, cream-based soups, and delicate seafood dishes. It provides a smooth and velvety texture to the final preparations.

Blond Roux:

Blond roux is cooked slightly longer than white roux, resulting in a golden hue. It has a slightly deeper flavor while still maintaining a delicate taste profile. Blond roux is versatile and commonly used in sauces like velouté, where a light yet flavorful thickening agent is required. It adds a hint of richness without overpowering the other ingredients.

Brown Roux:

Brown roux is cooked for a longer duration, achieving a darker color and a more pronounced nutty aroma. It offers a robust, toasty flavor with a deeper complexity. Brown roux is commonly employed in dishes such as gumbo, étouffée, and dark gravy. Its deep flavors provide a hearty foundation and a distinctive taste that enhances savory recipes.

Cooking Techniques for Making Roux

The process of making a roux involves a combination of precise heat control and constant stirring. Here are the essential cooking techniques to achieve a perfect roux:

Heat Control:

Maintaining the right heat is crucial when making a roux. Start by melting the fat over medium heat, ensuring it doesn’t burn or smoke. Adjust the heat as necessary to keep it at a gentle simmer throughout the cooking process. A moderate heat allows the flour to cook gradually, preventing it from becoming lumpy or burnt.

Constant Stirring:

Stirring is a critical step in making a roux. Once the flour is added to the melted fat, use a whisk or a wooden spoon to continuously stir the mixture. This prevents the flour from clumping and ensures it cooks evenly. Pay close attention to the edges of the pan to avoid any areas where the flour might settle and potentially burn.

Cooking Time:

The cooking time for a roux varies depending on the desired color and flavor. For a white roux, cook the mixture for just a few minutes until the raw flour taste dissipates. A blond roux requires slightly longer cooking, achieving a golden hue. If aiming for a brown roux, extend the cooking time until a rich, deep color is achieved. Remember to adjust the heat as needed to control the cooking process.

Patience and Precision:

Making a roux requires patience and precision. Take your time during the cooking process, ensuring each step is given the necessary attention. The gradual browning of the flour and the development of flavors cannot be rushed. Be mindful of the consistency and color, adjusting the cooking time accordingly to achieve the desired result.

Step-by-Step Guide to Making a Roux

Follow these step-by-step instructions to create a perfect roux:

  1. Start by selecting your desired fat, such as butter, vegetable oil, lard, or bacon fat. Measure out the required amount based on your recipe.
  2. Heat a heavy-bottomed saucepan or skillet over medium heat. Add the fat and allow it to melt completely.
  3. Once the fat has melted, gradually add the flour to the pan while continuously whisking or stirring with a wooden spoon. Ensure that the flour is fully incorporated into the fat, forming a smooth mixture.
  4. Keep stirring the mixture constantly to prevent lumps from forming and to ensure even cooking. Pay close attention to the edges of the pan, where the mixture tends to settle.
  5. Adjust the heat as necessary to maintain a gentle simmer. Cook the roux, stirring continuously, until it reaches the desired color. Remember that white roux should have no raw flour taste, blond roux should have a golden hue, and brown roux should have a rich, deep color.
  6. Once your roux has reached the desired color, remove it from the heat and transfer it to a separate bowl or immediately add other ingredients to the pan, as directed by your recipe.
  7. Incorporate the roux into your recipe, following the specific instructions provided. It will act as a thickening agent and impart flavor to your dish.

Remember, a roux should be used immediately or cooled and stored properly if not needed right away. Avoid overheating or burning the roux, as it can develop a bitter taste.
