Béchamel Sauce
Equipment
- medium saucepan
Ingredients
- 2 tablespoons butter sweet, unsalted
- 3 tablespoons all-purpose flour
- 1 cup milk
- salt & pepper to taste
- nutmeg freshly grated or ground, to taste
Instructions
Melt the Butter
- Add the flour to the melted butter. Whisk constantly for 1–2 minutes until smooth and slightly foamy.Goal: Cook out the raw flour taste while keeping the roux pale.

Add the Remaining Milk Gradually
- Slowly pour in the rest of the milk while whisking continuously. Keep the mixture moving so it stays smooth.Tip: Don’t rush—steady pouring = silky sauce.
Simmer & Thicken
- Reduce the heat to medium-low. Cook, whisking frequently, until the sauce thickens enough to coat the back of a spoon, about 5–7 minutes.Test: Run your finger across the spoon—if the line holds, it’s ready.
Season & Finish
- Add salt, white pepper, and a pinch of nutmeg (optional but classic). Stir well and taste.Adjust: Add more milk if too thick, simmer longer if too thin.

Béchamel Story
It is one of the grand or mother sauces of French cuisine. Unctuous, it tastes even richer than its ingredients would suggest. As a result, the finished product will be more reminiscent of cream than milk.
It is a little time-consuming but so worth the effort. Pronounced (bay-shah-mel), this classic is one of France’s five “Mother Sauces,” but no one knows when it was first created or by whom.
Most likely, it was first prepared by someone who worked for King Louis XIV (1643-1715) of France.
Some say it was either the Marquis Louis de Bechamel, the king’s chief steward, or Francois Pierre de la Varenne, the king’s chef, who dedicated the sauce to Louis de Bechamel. Either way, we know it starts with a roux made from butter and flour with boiled milk added to it.
