Ingredients:

  • 4 tablespoons (57g) Unsalted Butter or Vegetable Oil
  • 4 tablespoons (30g) All-Purpose Flour
  • Salt and Pepper (to taste, optional)

Instructions:

  1. In a saucepan over medium heat, melt the butter or heat the oil until shimmering.
  2. Add the flour to the melted butter/oil all at once.
  3. Immediately begin whisking the flour and fat together vigorously. Ensure no lumps remain. Reduce heat to medium-low, if needed.
  4. Continue cooking and stirring (or whisking) constantly. This is crucial to prevent burning and to cook out the raw flour taste.
  5. Watch the color carefully: White Roux (2-3 minutes, pale & foamy), Blond Roux (5-7 minutes, light golden), Brown Roux (15-20 minutes, rich brown & nutty), Dark Brown/Chocolate Roux (25-30 minutes, very dark, constant attention to avoid burning).
  6. Once the roux reaches your desired color, immediately remove the saucepan from the heat.
  7. Allow the roux to cool slightly before adding liquid. This can help prevent lumps. (Adding cold liquid to hot roux or hot liquid to cold roux also helps with lump prevention).
  8. Gradually whisk the roux into the warm or simmering liquid that you are trying to thicken. Whisk constantly until smooth.
  9. Simmer the sauce, stirring occasionally, until it reaches the desired consistency.
  10. Season with salt and pepper to taste (if desired).
