Make rich, creamy homemade mayonnaise in minutes using a blender. This failproof recipe uses simple ingredients and tastes better than store-bought versions for your sandwiches and salads.

Ingredients

Scale
  • 1 large egg yolk, room temperature
  • 1 teaspoon Dijon mustard
  • 1 teaspoon fresh lemon juice
  • 1/4 teaspoon salt
  • 1 cup neutral oil (like canola or light olive oil), room temperature

Instructions

  1. Place the egg yolk, Dijon mustard, lemon juice, and salt into the jar of an immersion blender or a narrow, tall container that fits your standard blender blade.
  2. Blend these ingredients together for about 15 seconds until they are combined and slightly lighter in color.
  3. With the blender running on medium speed, begin adding the oil in a very slow, thin stream. This step is crucial for preventing separation.
  4. Continue adding the oil slowly until about half of the oil is incorporated and the mixture begins to thicken significantly.
  5. Once the mixture is thick, you can increase the oil stream slightly, but keep it steady. Continue blending until all the oil is added and you have thick, smooth homemade mayonnaise.
  6. If the mayonnaise is too thick, stir in 1 teaspoon of warm water until you reach your desired consistency.
  7. Transfer the fresh condiment to an airtight container.

Notes

  • Use room temperature ingredients. Cold ingredients increase the chance of the mayonnaise separating.
  • If your mayonnaise separates (looks watery), place one teaspoon of warm water in a clean bowl. Slowly whisk in the separated mixture, one teaspoon at a time, until it emulsifies again.
  • This fresh mayonnaise is a perfect base for creamy salad dressing or a DIY sandwich spread.
