This classic parsley sauce starts with a simple butter and flour roux, enriched with milk into a smooth béchamel, then finished with plenty of chopped fresh parsley. It's a traditional accompaniment to poached fish, gammon, or boiled potatoes, and comes together in under 20 minutes with pantry staples.
Ingredients
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups whole milk
- 1/2 cup fresh parsley, finely chopped
- 1/2 teaspoon salt
- 1/4 teaspoon white pepper
- 1 tablespoon lemon juice
- 1 pinch freshly grated nutmeg
Method
-
Melt the butter in a 6-quart saucepan over medium heat until foaming but not browned.
-
Whisk in the flour and cook, stirring constantly, until the mixture is smooth and pale golden, about 1 minute, to form a roux.
-
Gradually pour in the milk in a slow stream, whisking constantly to prevent lumps from forming.
-
Increase heat to medium-high and bring the sauce to a gentle simmer, whisking frequently, until thickened enough to coat the back of a spoon.
-
Reduce heat to low and stir in the salt, white pepper, and nutmeg.
-
Stir in the chopped parsley and lemon juice, and cook for 1 minute more to warm the parsley through without dulling its color.
-
Taste and adjust seasoning with additional salt and pepper if needed, then serve warm.
