Equipment

Medium heavy-bottomed saucepan
Wire whisk
Wooden spoon or silicone spatula
Measuring cups and spoons
Small saucepan or microwave-safe bowl For warming milk

Ingredients

4 tablespoons unsalted butter ½ stick or 56g
¼ cup all-purpose flour 30g
2 cups whole milk 480ml, warmed
½ teaspoon salt
¼ teaspoon white pepper or black pepper
ground nutmeg Pinch, optional but traditional

Instructions

Pour milk into a small saucepan and warm over medium-low heat until hot to the touch but not boiling, or microwave in 30-second intervals.
Melt butter in a medium heavy-bottomed saucepan over medium heat. Once foaming, add flour all at once and whisk constantly for 2-3 minutes until light golden and slightly nutty-smelling.
Remove from heat and add warm milk ¼ cup at a time, whisking vigorously after each addition until smooth. Once half the milk is incorporated, add remaining milk more quickly.
Return to medium heat and bring to a gentle simmer. Continue whisking frequently and let simmer for 5-7 minutes until sauce thickens and coats the back of a spoon.
Remove from heat and whisk in salt, pepper, and nutmeg if using. Taste and adjust seasonings as needed.

Notes

Always use warm milk when adding to the roux to prevent lumps from forming.
Whisk constantly when making the roux and adding milk to ensure a smooth, lump-free sauce.
Don't let the roux brown too much - it should remain blonde for traditional bechamel.
If lumps do form, strain the sauce through a fine-mesh sieve or use an immersion blender.
For Mornay sauce variation, stir in 1 cup grated Gruyere or cheddar cheese until melted.
For a lighter version, use 2% milk and reduce butter to 3 tablespoons.
Add more warm milk a tablespoon at a time if sauce becomes too thick.
Store in airtight container in refrigerator for up to 4 days with plastic wrap pressed directly on surface to prevent skin formation.
Freeze in portions for up to 3 months. Thaw overnight in refrigerator before reheating.
Reheat gently over low heat, whisking frequently and adding milk if needed to restore consistency.
