A vibrant, homemade herb mayonnaise that transforms simple meals. Mastering the slow drizzle of oil creates a perfectly thick, stable emulsion. This fresh, customizable condiment is a foundational kitchen skill with incredible flavor.

Ingredients

Scale
  • 1 large egg yolk, at room temperature
  • 1 teaspoon Dijon mustard
  • 1 tablespoon lemon juice or white wine vinegar
  • 1/2 teaspoon fine sea salt, plus more to taste
  • 1 cup neutral oil (like avocado, grapeseed, or light olive oil)
  • 1/4 cup packed fresh soft herbs (parsley, dill, chives, tarragon), finely chopped
  • 1 small garlic clove, minced (optional)
  • Freshly cracked black pepper to taste

Instructions

  1. In a stable medium bowl, whisk together the egg yolk, Dijon mustard, lemon juice, and salt until smooth and slightly thickened.
  2. While whisking constantly and vigorously, begin adding the oil drop by drop for the first 1/4 cup to establish the emulsion.
  3. Once the mixture is thick and creamy, you can add the remaining oil in a very thin, steady stream, whisking continuously until all oil is incorporated and the mayonnaise is thick.
  4. Gently fold in the finely chopped fresh herbs and minced garlic (if using) until evenly distributed.
  5. Taste and adjust seasoning with more salt, pepper, or a squeeze of lemon juice as needed.

Notes

If the mayonnaise breaks, stop adding oil. In a fresh bowl, whisk 1 tsp of Dijon mustard or water, then slowly whisk in the broken mixture a little at a time to re-emulsify. Store in an airtight container in the refrigerator for 3-4 days.
