📝 About This Recipe

This classic French vinaigrette is the soul of Parisian bistro cooking, offering a perfect balance of sharp acidity, pungent mustard, and silky fats. Unlike its thinner counterparts, this dressing uses high-quality Dijon as an emulsifier to create a creamy, clingy texture that coats leaves without wilting them. It is an indispensable technique for any home cook looking to elevate simple greens into a sophisticated course.

🥗 Ingredients

The Acid Base

  • 2 tablespoons Sherry Vinegar (or high-quality Red Wine Vinegar)
  • 1 teaspoon Fresh Lemon Juice (provides a bright top note)
  • 1 small Shallot (minced extremely fine)

The Emulsifiers and Seasoning

  • 1 tablespoon Dijon Mustard (Traditional smooth style, like Maille)
  • 1/2 teaspoon Honey or Maple Syrup (to balance the sharpness)
  • 1/2 teaspoon Fine Sea Salt (plus more to taste)
  • 1/4 teaspoon Freshly Cracked Black Pepper (use a fine grind)
  • 1/4 teaspoon Dried Herbes de Provence (optional, for a floral depth)

The Oil Blend

  • 1/2 cup Extra Virgin Olive Oil (fruity and high quality)
  • 2 tablespoons Neutral Oil (Grapeseed or Avocado oil to lighten the texture)

The Fresh Finish

  • 1 tablespoon Fresh Chives (finely snipped)
  • 1 teaspoon Fresh Italian Parsley (minced)
  • 1 teaspoon Cold Water (the secret to a stable emulsion)

👨‍🍳 Instructions

  1. 1

    Begin by macerating the shallots: Place the finely minced shallots in a medium glass or stainless steel mixing bowl.

  2. 2

    Pour the sherry vinegar and lemon juice over the shallots. Add the sea salt and whisk briefly. Let this sit for 5-10 minutes; the acid will soften the bite of the raw shallot and infuse the vinegar with flavor.

  3. 3

    Add the Dijon mustard and the honey to the vinegar mixture. Whisk vigorously until the mustard is fully incorporated and the mixture looks slightly frothy.

  4. 4

    Whisk in the black pepper and the dried Herbes de Provence (if using) so the spices can begin to bloom in the acidic base.

  5. 5

    Combine your olive oil and neutral oil in a small measuring cup with a spout for easy pouring.

  6. 6

    Place a damp kitchen towel in a ring on your counter and set the bowl inside it. This stabilizes the bowl so you can whisk with one hand and pour with the other.

  7. 7

    Begin adding the oil mixture literally drop by drop while whisking constantly. This slow start is crucial for building the emulsion.

  8. 8

    Once the mixture begins to thicken and look creamy, you can increase the flow of oil to a very thin, steady stream, whisking all the while.

  9. 9

    Halfway through the oil, whisk in the teaspoon of cold water. This helps stabilize the emulsion and prevents the dressing from becoming too heavy or 'greasy' on the palate.

  10. 10

    Continue whisking in the remaining oil until the dressing is thick, glossy, and pale in color.

  11. 11

    Gently fold in the fresh chives and parsley. Do not over-whisk after adding fresh herbs to avoid bruising them.

  12. 12

    Taste the vinaigrette with a leaf of the lettuce you intend to serve. Adjust seasoning with an extra pinch of salt or a drop more vinegar if it feels too oily.

  13. 13

    Transfer to a glass jar. If not using immediately, store in the refrigerator, but bring to room temperature for 15 minutes before serving to liquefy the olive oil.

💡 Chef's Tips

Always macerate your shallots in the vinegar first to remove their 'sulfuric' sting. Use a high-quality Dijon mustard; it acts as the glue that keeps the oil and vinegar from separating. If the dressing breaks (separates), whisk a teaspoon of mustard in a clean bowl and slowly whisk the broken dressing into it. For the best texture, use a mix of extra virgin olive oil and a neutral oil so the olive flavor doesn't overpower the delicate greens. Always dress your salad in a large bowl, tossing gently by hand to ensure every leaf is thinly and evenly coated.

🍽️ Serving Suggestions

Drizzle over a classic Salade Verte (butter lettuce and radishes). Use as a marinade for grilled chicken or firm white fish like Halibut. Serve alongside a warm goat cheese tart or a classic Quiche Lorraine. Pair with a crisp, chilled glass of Sancerre or Sauvignon Blanc to complement the acidity. Excellent as a dip for steamed artichokes or blanched asparagus.
