Recipe: Burnt Butter Mayo

Inspired by the Bacon Butter Burger by Burger & Beyond, I attempted to make my own version of their burnt butter mayo at home. Its rich, silky goodness is an excellent replacement for mayo in any burger and probably works well as a mayo replacement in other foods (whatever they are).

This is a simple mayonnaise recipe that replaces the oil entirely with browned butter.


  • 1 egg yolk
  • 50g pack of butter
  • 2 tsp lemon juice
  • 1 tsp cold water
  • 1/4 tsp salt


  1. Start by melting the butter in a pan.
  2. Cook the butter for 5-10 minutes on a medium heat, until it turns brown and starts to smell nutty.
  3. While you wait for the butter to cook, mix the egg yolk, lemon juice, water and salt together in a mixing bowl and whisk together until thoroughly blended.
  4. Once the butter has browned, set it aside in a jug and let it cool to slightly warmer than room temperature.
  5. Now we make the mayo. Whisking constantly, incorporate a drop of butter at a time slowly into the mix.
  6. Once you’ve added half the butter drop by drop, pour the rest in a thin stream, whisking all the time, until you have added all the butter.
  7. Once made it will keep in the fridge for at least 4 weeks.
