No reviews

A foolproof recipe for creamy, silky-smooth homemade mayonnaise. Using an immersion blender method, it guarantees a perfect emulsion every time in just five minutes. The fresh, clean flavor transforms sandwiches, salads, and dips.

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
  • 1 cup (240 ml) neutral-flavored oil (like avocado, grapeseed, or light olive oil)

Instructions

  1. Combine the egg yolk, Dijon mustard, lemon juice, and salt in a tall, narrow jar that fits your immersion blender head.
  2. Pour all of the oil directly on top of the yolk mixture. Do not stir; let the layers separate.
  3. Place the immersion blender at the very bottom of the jar. Turn it on high and hold it completely still for 10-15 seconds until a thick, white mayonnaise forms at the base.
  4. Once the base is thick, slowly and gently lift the blender up through the oil to pull the remaining oil down and emulsify it completely.
  5. Taste the mayonnaise and adjust seasoning with more salt or lemon juice if desired.

Notes

For a regular blender or food processor: blend yolk, mustard, lemon, and salt first. With the machine running on low, drizzle the oil in a very thin, steady stream until thick. Always use room temperature ingredients for best results. Store in an airtight jar in the refrigerator for up to 1 week.
