What is a white sauce (béchamel)?
A white sauce, also known as béchamel, is a foundational French mother sauce. It's made from a simple roux (butter and flour) cooked together and then gradually whisked with warm milk (or cream for a richer version) until it thickens into a smooth, creamy consistency. Its versatility makes it a staple in countless recipes, particularly when paired with fish.
How to Make a Basic White Sauce for Fish
This recipe provides a simple, foolproof method for creating a delicious white sauce that beautifully enhances the flavor of your fish.
Ingredients:
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 2 cups whole milk (or a combination of milk and cream for extra richness)
- 1/4 teaspoon salt
- 1/4 teaspoon white pepper
- Pinch of nutmeg (optional, but highly recommended for fish dishes)
Instructions:
- Melt the butter: In a medium saucepan over medium heat, melt the butter completely.
- Make the roux: Whisk in the flour and cook for 1-2 minutes, stirring constantly, until the mixture is smooth and bubbly. This is crucial to avoid lumps. Do not brown the roux.
- Gradually add the milk: Slowly whisk in the warm milk, a little at a time, ensuring each addition is fully incorporated before adding more. This prevents lumps and ensures a smooth, creamy texture.
- Simmer and thicken: Continue whisking constantly as the sauce simmers gently. The sauce will thicken as it cooks. This usually takes about 5-7 minutes.
- Season: Stir in the salt, pepper, and nutmeg (if using). Taste and adjust seasoning as needed.
What are some variations of white sauce for fish?
The basic white sauce is incredibly versatile. You can easily customize it to create a range of delicious flavors to complement different types of fish:
- Lemon White Sauce: Add the zest and juice of 1/2 a lemon during the last few minutes of cooking.
- Garlic White Sauce: Sauté 2-3 minced garlic cloves in the butter before adding the flour.
- Herb White Sauce: Stir in 1-2 tablespoons of chopped fresh herbs (dill, parsley, chives) during the last minute of cooking.
- Creamy White Sauce: Substitute half the milk with heavy cream for an extra decadent sauce.
How do I prevent lumps in my white sauce?
Lumps are the enemy of a smooth white sauce! Here are some tips to avoid them:
- Use low heat: Cooking the roux over low to medium heat prevents burning and ensures a smooth blend.
- Whisk constantly: Continuous whisking is essential, especially when adding the milk.
- Use warm milk: Adding warm milk gradually prevents the flour from clumping.
- Strain the sauce: If you still end up with lumps, strain the sauce through a fine-mesh sieve.
Can I make a white sauce ahead of time?
Yes, you can make a white sauce ahead of time. Store it in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop, stirring frequently, until warmed through. Be careful not to let it scorch.

- Cod
- Haddock
- Tilapia
