Roux the Day
A practical guide to making roux, from Chef Corn’s Kitchen
Roux is a simple mixture of flour and fat cooked together. It helps thicken sauces, gravies, soups, and gumbo—and the longer it cooks, the deeper its color and toasted flavor become.
What you’ll need
-
All-purpose flour
-
A cooking fat, such as butter, neutral oil, or bacon drippings
-
A heavy-bottomed pan
-
A whisk or sturdy spoon
For a traditional roux, start with equal weights of flour and fat. Use a kitchen scale for the most consistent results.
The classic method
-
Melt the fat in a heavy-bottomed pan over medium-low to medium heat.
-
Whisk in the flour until smooth.
-
Keep stirring as the roux cooks. Choose the color that suits your dish: pale for a mild flavor, or darker for a deeper toasted taste.
-
When it reaches the color you want, gradually whisk in your recipe’s liquid. Add it a little at a time, stirring until smooth before adding more.
-
Simmer and stir until your sauce or gravy reaches the consistency you want.
Chef Corn’s flour-first variation
I sometimes brown the flour in the pan first, stirring it often so it colors evenly. Then I add the fat and stir until the mixture is smooth. I let it cook for another minute or two before gradually whisking in the liquid.
This is a different route to a browned roux. Keep the heat controlled, stay with the pan, and stir often.
A few helpful reminders
-
Roux color is a guide; the smell and flavor matter too. The raw flour smell should cook off.
-
A darker roux takes patience. Keep stirring and watch it closely.
-
If the roux develops black flecks or smells burnt, start over; that bitterness can carry into the finished dish.
-
Add liquid gradually and whisk well to help keep the mixture smooth.
Roux is one of those kitchen basics that gets easier with practice. Take your time, keep stirring, and let the color tell you when it’s ready.
