What is Cheese Roux

Roux is a classic basic in cooking that forms the foundation of countless dishes. Understanding how to make one opens up a world of possibilities in the kitchen.

What is Roux?

Roux is a mixture of equal parts butter and flour cooked together. As the butter melts, the flour particles get coated in fat. Heating causes starch granules in the flour to swell and absorb liquid better.

This roux mixture thickens up liquids tremendously while adding a lovely richness. The more roux used, the thicker the resulting mixture becomes.

There are three main types of roux:

  • White roux: Cooked just until the raw flour taste disappears, about 3-5 minutes. It maintains a light color and works well for delicate dishes.
  • Blonde roux: Cooked a bit longer, around 5-10 minutes, allowing more complex nutty flavors to develop.
  • Brown roux: Cooked for a longer time until it becomes a dark brown color, up to 30 minutes. Imparts an intense, smoky depth.

Key Takeaway: Roux is an equal part mixture of butter and flour cooked together to thicken sauces.
