  • 1 large egg
  • ½ tablespoon lemon juice
  • ½ teaspoon kosher salt
  • ½ teaspoon ground mustard
  • 1 cup extra light olive oil be sure it's extra light and not extra virgin or you will be very disappointed


  • Add the egg, lemon juice, salt, and mustard in a jar wide enough to fit the immersion blender in. Add in the oil.
  • Insert the blender all the way to the bottom of the jar and turn it on.
  • Don't move the blender for a good 20-30 seconds. You'll notice the mayo starting to form at the bottom and it will slowly climb its way up the jar. At this point, you can move the blender up and down to blend in the the oil hanging out at the top. Be careful not to take the stick completely out of the jar while it's on!
  • And just like that, you have thick, creamy homemade mayo.


Mayo can also be made by hand, but requires some elbow grease. It can also be made in a regular blender, though in my experience, it doesn't always come out good. Both of these methods require patience which is why I'm a huge fan of the immersion blender. No muss. No fuss!
