Perfect French Vinaigrette Every Time
A proper French vinaigrette is the foundation of great salads — sharp vinegar balanced with Dijon's tang, then unified with golden olive oil into silky perfection. Master this classic technique and you'll never buy bottled dressing again.
At its heart, vinaigrette is an impossibility — oil and vinegar don't mix. They sit in separate layers like strangers at a party, until you introduce them to Dijon mustard. That single teaspoon contains natural lecithin, the matchmaker that convinces these opposites to dance together in perfect suspension.
The French have been making this alchemy work for centuries, not because they had secret ingredients, but because they understood the technique. The key isn't what you put in the bowl — it's how you coax those liquids into cooperation. Rush the oil and you'll get broken puddles. Add it patiently, whisking like you mean it, and you'll watch separate elements transform into something golden and unified.
Once you nail this basic ratio and technique, you own the template for countless variations. A splash of shallot vinegar here, a whisper of honey there, maybe some fresh herbs from the garden. But start here, with this clean, sharp classic that lets you taste exactly what good olive oil and proper technique can accomplish together.
Absolutely — white wine vinegar works beautifully and creates a slightly more delicate flavor. You can also try champagne vinegar for something extra elegant, or even apple cider vinegar for a touch more sweetness.
Not at all — separation is completely normal when vinaigrette sits. Just shake the jar vigorously or re-whisk in a bowl, and the emulsion will come right back together good as new.
It keeps beautifully in the refrigerator for up to a week, sometimes longer. The acid in the vinegar actually helps preserve the mixture, just like it does in pickling.
You can skip the mustard, but you'll lose the emulsifying power that keeps everything together. The result will be more like a broken vinaigrette that needs constant stirring, rather than a smooth, unified dressing.
