There’s something magical about a well-made white sauce draped over a perfectly cooked fillet of fish—it’s comforting, flavorful, and surprisingly easy to pull together. This lemon-chive white sauce brings tang and herbal brightness to any seafood dish, making it a simple yet special treat.

Ingredients

- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 cup whole milk (or half-and-half for extra creaminess)
- Juice of half a lemon
- 1 teaspoon finely grated lemon zest
- 2 tablespoons chopped fresh chives
- Salt and freshly ground black pepper, to taste
Instructions
In a small saucepan set over medium-low heat, melt the butter until it begins to bubble gently. Stir in the flour and whisk to create a roux, cooking for about one minute to lightly toast the flour—this removes any raw flour taste and helps develop a rich, nutty aroma.
Gradually pour in the milk, whisking constantly to keep it smooth. As the mixture warms and thickens, add the lemon juice and lemon zest, continuing to stir. You can season with a pinch of salt and black pepper at this stage. Adjust the thickness by adding a splash more milk if necessary; you’re aiming for a velvety sauce that coats the back of a spoon.

Just before serving, stir in the fresh chives. The gentle touch of greenery and bright lemon flavor will bring out the best in your fish. Serve immediately by spooning the sauce over your favorite fillet—salmon, cod, trout, or tilapia all shine under this creamy, citrusy blanket.
The beauty of this Lemon-Chive White Sauce lies in its simplicity and versatility. Anyone seeking a quick but luxurious enhancement to a fish dish will love adding this sauce to their repertoire. Health-wise, feel free to swap in low-fat milk if you prefer, or experiment with almond milk for a lighter alternative. Enjoy it drizzled over steamed vegetables, whisk in a bit of white wine for a refined twist, or sprinkle in fresh dill for a more herbaceous punch. No matter your preference, this silky sauce easily adapts to fit your needs and promises to bring a flavorful finish to your favorite fish dinner.
