Classic Béchamel Sauce

FAQ
What is béchamel sauce?
Béchamel is one of the five classic French mother sauces. Made with butter, flour, and milk to create a smooth, creamy white sauce.
Do I have to use whole milk?
No. Whole milk gives the creamiest sauce, but 2% milk works too.
What is béchamel sauce used for?
No. Whole milk gives the creamiest sauce, but 2% milk also works. For a dairy-free option, unsweetened almond milk, oat milk, or soy milk can also be used. Keep in mind the sauce may not be quite as rich.
How do I keep my béchamel from getting lumpy?
Slowly add the milk to the roux while whisking constantly. This helps create a smooth sauce.
Can I make this into a cheese sauce?
Yes. Remove the sauce from the heat, then stir in your favourite shredded cheese until melted and smooth.
Chef’s Tips
- Warm the milk first. It blends into the roux more easily and gives you a smoother sauce.
- Pour the milk in a little at a time, whisking well after each addition to help keep the sauce lump-free.
- Don’t let the roux brown. For a classic béchamel, you want to keep it nice and pale.
- If the sauce gets a little too thick, just whisk in a splash of warm milk until it’s the consistency you like.

Ingredients
- 2 tablespoons butter
- 2 tablespoons all-purpose flour
- 2 cups milk whole milk works best
- Salt to taste
- Freshly ground white pepper to taste
- A pinch of ground nutmeg optional, but recommended
Instructions
- In a saucepan, melt the butter over medium heat.
- Add the flour to the melted butter, whisking constantly to form a smooth paste. Cook for 1–2 minutes to eliminate the raw flour taste. Be careful not to let it brown.
- Slowly pour in the milk while whisking continuously to prevent lumps. Keep whisking until the mixture thickens.
- Once the sauce has thickened to your desired consistency (about 5-7 minutes), season with salt, pepper, and a pinch of nutmeg, if using.
- Remove from heat and use immediately, or cover to keep warm.
Notes
Variations
- Cheeses: Add shredded Gruyère, cheddar, Parmesan, or Swiss cheese to make a cheese sauce.
- Flavour Add-ins: Infuse the milk with a bay leaf, onion, or garlic before adding it to the roux for extra flavour. Strain before using.
- Creaminess: Replace some of the milk with cream for a richer sauce.
- Whole milk creates the creamiest texture, but 2% milk will still work.
For an extra smooth sauce, strain it through a fine-mesh sieve before serving. - Béchamel should be smooth and creamy, not overly thick. Adjust with milk as needed.
- Fridge:
Store in an airtight container for up to 3 days. Press plastic wrap directly onto the surface to help prevent a skin from forming. - Freezer:
Freezing is not recommended, as the sauce can separate and become grainy once thawed. - Reheating:
Warm gently over low heat, whisking often.- Add a splash of milk to loosen the sauce if needed.
