Make creamy, restaurant-quality garlic aioli quickly using simple ingredients. This versatile sauce is perfect for dipping fries or spreading on sandwiches.

Ingredients

Scale
  • 1 large egg yolk
  • 1 teaspoon Dijon mustard
  • 1 teaspoon fresh lemon juice
  • 1/2 teaspoon salt
  • 1 clove garlic, minced very finely or grated
  • 1 cup neutral oil (like canola or grapeseed)
  • 1 tablespoon hot water (optional, for thinning)

Instructions

  1. Place the egg yolk, Dijon mustard, lemon juice, salt, and minced garlic into a medium bowl.
  2. Whisk these ingredients together until they are well combined and slightly pale.
  3. Begin adding the oil very slowly, drop by drop, while whisking constantly and vigorously. This slow addition is crucial for emulsification.
  4. Once about one quarter of the oil is incorporated and the mixture thickens, you can increase the oil stream to a thin, steady drizzle, still whisking constantly.
  5. Continue adding the oil until all of it is incorporated and the mixture is thick and creamy.
  6. If the aioli is too thick, whisk in 1 tablespoon of hot water until you reach your desired consistency.
  7. Taste and adjust salt or lemon juice if needed.

Notes

  • For a quicker, mayo-based version, skip steps 1-3 and combine 1 cup of good quality mayonnaise with the garlic, lemon juice, and salt, then whisk until smooth.
  • Use a food processor or immersion blender for faster emulsification, but add the oil very slowly.
  • If the aioli breaks (separates), whisk a fresh egg yolk in a clean bowl and slowly whisk the broken mixture into the new yolk.
