1. Use the white sauce right away with stews, pasta, or lasagna. To store it, cover it while still hot with foil without touching the surface so no skin forms, and reheat over low heat, stirring constantly.

## Additional Tips

### Make it creamier

Replace part of the milk with cream or stir in a little grated cheese while it cooks.

### Add herbs for pasta

Fresh basil or parsley personalize the sauce for your favorite pasta.

### Fix a thin sauce

Whisk in a little flour dissolved in cold water and cook a few minutes more, stirring constantly.

| Original ingredient | Substitute | Ratio | Flavor note |
| --- | --- | --- | --- |
| Whole milk | Skim milk | 400 ml | Less creamy |
| Butter | Olive oil | 2 tablespoons | Lighter flavor |
| Part of the milk | Cream | 100 ml | Richer |
| Plain | With grated cheese | 2 tablespoons | Mornay style |

## Frequently Asked Questions (FAQs)

### 1. Can I make bechamel with skim milk?

Yes, but it will be a little less creamy. Whole milk gives more smoothness and body.

### 2. Can I make white sauce without butter?

Yes, with olive oil or margarine, though the flavor changes slightly. Olive oil is a lighter option.

### 3. How do I thicken bechamel?

Add a little flour dissolved in cold water and cook a few minutes more, stirring constantly to avoid lumps.

### 4. How long does white sauce keep?

Up to 3 days in the fridge, well covered so no skin forms. It can be frozen, but it tends to separate, so reheat it slowly and stir well.

## History of Bechamel

Bechamel is one of the mother sauces of classic French cooking. A popular theory says it came from Florence with Catherine de’ Medici’s cooks when she married the future Henry II of France in 1533, and its name is linked to the Marquis Louis de Béchameil, steward to Louis XIV.
