Can You Make a Roux with Margarine? | A Culinary Exploration

Making a Roux in a Pan With Butter Oil Cornstarch or Flour

A roux, the cornerstone of many classic French sauces and a staple in various global cuisines, is a mixture of equal parts fat and flour cooked together to create a smooth, lump-free thickening agent. Traditionally, butter is the fat of choice in most recipes. However, as dietary needs and preferences change, there is a growing curiosity about viable alternatives. One such alternative is margarine, a vegetable oil-based fat often used as a butter substitute. So, can you make a roux with margarine?

The Traditional Roux

Before diving into the margarine alternative, it’s essential to understand what a traditional roux involves. A roux typically uses clarified butter or whole butter and all-purpose flour. It can be cooked to various stages: white, blond, or brown, depending on the specific recipe requirements. The mixture serves as a base for dishes like béchamel sauce, gumbo, or gravy.

Why Consider Margarine?

Margarine is often considered for a variety of reasons:

  1. Dietary restrictions: Margarine can be a non-dairy alternative, suitable for lactose intolerant individuals or those following a vegan diet.
  2. Lower saturated fat content: Some people opt for margarine due to its lower saturated fat profile than butter.
  3. Availability and cost: Margarine is generally more affordable and has a longer shelf life than butter.

Chemical Differences Between Butter and Margarine


Both butter and margarine are fats that can be mixed with flour to create a roux, but they have distinct differences. Butter contains milk solids and water in addition to fat, while margarine is an emulsion of vegetable oils and water, often with added salt and emulsifiers. The absence of milk solids in margarine means a less nuanced flavor profile but also fewer opportunities for the roux to burn.

And I always like to add to any comparison of butter and margarine a significant difference that is a game changer for me; while butter is a natural product, margarine is not. Margarine is a manufactured product created as a less expensive alternative to butter.

Practical Aspects: Making a Roux with Margarine

Now, let’s get down to the practical aspects of making a roux with margarine. The process remains fundamentally the same:

  1. Equal Parts: Use equal parts margarine and flour by weight.
  2. Heat: Melt the margarine in a pan over low to medium heat.
  3. Mix: Add flour to the melted margarine and stir constantly to combine.
  4. Cook: Continue cooking to the desired color—white, blond, or brown—stirring continuously to prevent burning.

Texture and Flavor

Because margarine has a higher water content, you may find that the roux is somewhat softer or looser than when made with butter. This issue can usually be resolved by cooking the roux a bit longer to allow the excess water to evaporate.

In terms of flavor, margarine lacks the rich, creamy undertones that butter offers. While this may not be a significant concern in strongly flavored dishes like gumbo, it might be noticeable in subtler sauces like béchamel. You can compensate for the lack of depth by adding a touch more seasoning or using a well-flavored broth or stock.

Tips for Success

  1. Choose High-Quality Margarine: Opt for margarine with a higher fat content, ideally above 80%, to get closer to the consistency of traditional roux.
  2. Stir Constantly: The key to a smooth roux is constant stirring, regardless of the fat used.
  3. Experiment: Feel free to experiment with the proportions and cooking times to find the perfect roux for your specific dish.


In summary, yes, you can make a roux with margarine. It provides a reasonable alternative for those with dietary restrictions, a preference for lower saturated fats, or budget constraints. While the resulting roux may differ slightly in texture and flavor, it can still be an effective thickening agent in various dishes. Remember, cooking is as much about experimentation as it is about tradition, so don’t hesitate to try using margarine in your next roux.
