WHAT IS A ROUX
A roux is made of flour and fat cooked together until it reaches a specific color.
It is used as a thickening agent for gravy, sauces, soups, and stews and have been used in French cooking for hundreds of years to thicken sauce.
The flour is added with the fat to the stove top, blended until smooth, and cooked to the desired color.
The lighter the roux the more thickening power it has.
Once the roux is the desired color liquids like stock are added.
People often see instructions like “brown the flour” and avoid this step because they aren’t making brown gravy.
Browning flour means you’re cooking the flour. This removes the flour flavor so it won’t ruin the taste of your gravy.

Is roux better with oil or butter?
It really doesn’t make much of a difference if you use butter or oil for your roux except for the flavor. However, if you are dairy free or vegan it is butter to use oil because butter cannot be eaten.
What is the ratio of flour to oil in a roux?
To make a roux with oil you will want 1/4 less oil than you have flour.
While people often say you can use a 1:1 ratio, they are not factoring in the fact that butter and oil are not completely interchangeable because butter contains water where oil does not.
So, just like when baking with oil, you need 3/4 cup of oil for every 1 cup of butter.
What Kind of Oil to Use
Neutral oils like vegetable oil, safflower oil, and sunflower seed oil work well when making a roux with oil.
However, you can also use oils like olive oil and avocado oil when making a roux, though there may be a slight shift in the flavor if you do.
