After years of perfecting this recipe in my kitchen, I can confidently say this is the only white sauce recipe you’ll ever need.

Common Questions Answered
Q: Why did my sauce turn out lumpy?
A: Lumpy sauce usually results from adding cold milk too quickly or not whisking constantly during milk addition. Always use room temperature milk and add it gradually while whisking continuously.
Q: Can I make this sauce ahead of time?
A: Yes! You can make it up to 5 days ahead and store it in an airtight container in the refrigerator. Place plastic wrap directly on the surface to prevent a skin from forming.
Q: How can I make my sauce thicker or thinner?
A: To thicken, cook longer while stirring constantly. To thin, gradually whisk in warm milk until desired consistency is reached.
Q: Can I use plant-based milk?
A: Yes, unsweetened soy or oat milk works best as alternatives. Note that the texture might be slightly different from traditional dairy-based sauce.
Q: Why does my sauce sometimes separate when reheating?
A: This happens when reheating too quickly or at too high a temperature. Reheat gently over low heat, whisking constantly to recombine.
