When it comes to cooking, there are few techniques as fundamental as making a roux. A mixture of flour and fat, roux is used to thicken sauces, soups, and stews, and is a staple of many cuisines, particularly in French, Italian, and Cajun cooking. Traditionally, butter is the fat of choice for making roux, but with the growing popularity of olive oil, many cooks are wondering if they can use olive oil instead of butter in roux. In this article, we’ll explore the pros and cons of using olive oil in roux, and provide some tips for making the perfect roux, regardless of which fat you choose.
The Role of Fat in Roux
Before we dive into the specifics of using olive oil in roux, it’s worth taking a closer look at the role of fat in this fundamental cooking technique. Fat serves several purposes in roux:
- Flavor: Fat adds flavor to the roux, which is then imparted to the dish it’s used in. Different types of fat have distinct flavor profiles, which can enhance or detract from the overall taste of the dish.
- Texture: Fat helps to create a smooth, even texture in the roux, which is essential for thickening sauces and soups.
- Browning: Fat can contribute to the browning of the roux, which is a desirable outcome in many cases. Browning occurs when the starches in the flour react with the heat and the fat, creating new flavor compounds and a rich, nutty flavor.
Butter vs Olive Oil: A Comparison
So, how do butter and olive oil stack up when it comes to making roux? Here are some key differences to consider:
- Flavor: Butter has a rich, creamy flavor that is often associated with French cuisine. Olive oil, on the other hand, has a fruity, peppery flavor that is commonly used in Mediterranean cooking.
- Smoke Point: The smoke point of a fat is the temperature at which it begins to break down and smoke. Butter has a relatively low smoke point of around 320°F (160°C), while olive oil has a higher smoke point of around 420°F (220°C). This means that olive oil is less likely to burn or smoke when making roux.
- Cost: Butter is generally more expensive than olive oil, particularly if you’re using high-quality, European-style butter.
Using Olive Oil in Roux: Pros and Cons
So, can you use olive oil instead of butter in roux? The answer is yes, but there are some pros and cons to consider:
- Pros:
- Olive oil has a higher smoke point than butter, which makes it less likely to burn or smoke when making roux.
- Olive oil is generally less expensive than butter.
- Olive oil can add a fruity, peppery flavor to the roux, which can be desirable in certain dishes.
- Cons:
- Olive oil can make the roux slightly more difficult to work with, as it can be more prone to separating or becoming too greasy.
- Olive oil may not provide the same level of browning as butter, which can result in a less flavorful roux.
Making the Perfect Roux with Olive Oil
If you’ve decided to use olive oil in your roux, here are some tips for making the perfect roux:
- Use a high-quality olive oil: Choose a high-quality, extra-virgin olive oil that has a rich, fruity flavor.
- Use the right ratio of flour to fat: The traditional ratio for roux is 1 part flour to 1 part fat. You can adjust this ratio to suit your needs, but keep in mind that using too much fat can result in a greasy roux.
- Heat the oil slowly: Heat the olive oil slowly over low heat, whisking constantly, until it reaches the desired temperature.
- Add the flour gradually: Add the flour gradually, whisking constantly, until the mixture is smooth and even.
- Cook the roux slowly: Cook the roux slowly over low heat, whisking constantly, until it reaches the desired color.
Tips for Making a Darker Roux with Olive Oil
One of the challenges of using olive oil in roux is achieving a darker color. Here are some tips for making a darker roux with olive oil:
- Use a higher ratio of flour to fat: Using a higher ratio of flour to fat can help to create a darker roux.
- Cook the roux for a longer period of time: Cooking the roux for a longer period of time can help to create a darker color.
- Add a small amount of butter or other fat: Adding a small amount of butter or other fat can help to enhance the browning of the roux.

What is a roux and why is it important in cooking?
A roux is a mixture of flour and fat that is used as a thickening agent in many sauces, soups, and stews. It is an essential component of many cuisines, particularly in French, Italian, and Cajun cooking. The roux serves as a base for the dish, adding flavor, texture, and body to the final product.
The quality of the roux can make or break the dish, which is why the choice of fat is crucial. The fat used in the roux can affect the flavor, color, and texture of the final product. In this article, we will explore the differences between using butter and olive oil in a roux, and which one is best suited for your cooking needs.
What are the benefits of using butter in a roux?
Butter is a popular choice for making a roux because it adds a rich, nutty flavor to the dish. It also has a high smoke point, which means it can be heated to a high temperature without burning or smoking. This makes it ideal for making a dark roux, which is a staple of many Cajun and Creole dishes.
However, butter can also add a lot of calories to the dish, which may be a concern for health-conscious cooks. Additionally, butter can be expensive, especially if you are using high-quality, European-style butter. Despite these drawbacks, butter remains a popular choice for making a roux because of its rich flavor and versatility.
What are the benefits of using olive oil in a roux?
Olive oil is a healthier alternative to butter, with fewer calories and less saturated fat. It also has a distinct, fruity flavor that can add depth and complexity to the dish. Additionally, olive oil is often less expensive than butter, making it a more budget-friendly option.
However, olive oil has a lower smoke point than butter, which means it can burn or smoke if heated too high. This can result in a bitter, unpleasant flavor that can ruin the dish. To avoid this, it’s best to use a mild or light olive oil, and to heat it gently when making the roux.
How do I choose between butter and olive oil for my roux?
The choice between butter and olive oil ultimately comes down to personal preference and the type of dish you are making. If you want a rich, nutty flavor and a dark roux, butter may be the better choice. However, if you are looking for a healthier, lighter option with a fruity flavor, olive oil may be the way to go.
It’s also worth considering the other ingredients in the dish and how they will interact with the roux. For example, if you are making a seafood gumbo, you may want to use olive oil to complement the delicate flavor of the seafood. On the other hand, if you are making a hearty beef stew, butter may be a better choice to add richness and depth to the dish.
Can I use other types of fat in a roux?
Yes, there are many other types of fat that you can use in a roux, including vegetable oil, coconut oil, and lard. Each of these options has its own unique flavor and characteristics, and can be used to create a variety of different dishes.
For example, vegetable oil is a neutral-tasting oil that can be used to make a light, delicate roux. Coconut oil, on the other hand, has a distinct, tropical flavor that can add a unique twist to the dish. Lard, which is rendered pork fat, has a rich, savory flavor that is often used in traditional Southern cooking.
How do I make a roux with butter or olive oil?
To make a roux with butter or olive oil, simply melt the fat in a pan over medium heat. Then, gradually add the flour, whisking constantly to avoid lumps. Continue to cook the roux for several minutes, stirring constantly, until it reaches the desired color and consistency.
The key to making a good roux is to cook it slowly and patiently, stirring constantly to avoid burning or scorching the fat. This can take several minutes, but the end result is well worth the effort. With practice and patience, you can create a rich, flavorful roux that will elevate your cooking to the next level.
What are some common mistakes to avoid when making a roux?
One of the most common mistakes to avoid when making a roux is burning or scorching the fat. This can happen if the heat is too high, or if the roux is not stirred constantly. To avoid this, it’s best to cook the roux over medium heat, stirring constantly, until it reaches the desired color and consistency.
Another common mistake is adding the flour too quickly, which can result in lumps or a gritty texture. To avoid this, it’s best to add the flour gradually, whisking constantly to avoid lumps. With practice and patience, you can create a smooth, creamy roux that will elevate your cooking to the next level.
