The ingredients for miso mayo arranged in small glass bowls including kewpie mayonnaise, mirin, white miso paste and hondashi (an optional ingredient).
  • Mayonnaise: Japanese Kewpie mayonnaise is the star of this miso mayo recipe. It’s richer and creamier than regular store-bought mayonnaise, and it adds an extra layer of umami flavour. If Kewpie mayo isn’t available, you can use regular heavy mayonnaise or plant-based mayonnaise.
  • Miso paste: White miso paste is the key ingredient. It adds a subtle umami flavour and creaminess to the mayonnaise. You can also use red miso or yellow miso paste. For a more intense umami flavour, double the amount of miso paste. Use gluten-free miso if you need a gluten-free mayo sauce. Or try one of these miso substitutes if you’ve run out.
  • Mirin: This sweet Japanese rice wine adds complexity and sweetness to the miso mayo. If you don’t have any, substitute the mirin with a teaspoon of sake and half a teaspoon of white sugar. Or simply add a touch of sweetness with a splash of maple syrup.
  • Hondashi: This optional Japanese fish stock powder gives the miso mayonnaise an extra savoury depth. If you don’t have any, leave it out.

Total Time5 minutes


  • ¼ cup Japanese kewpie mayonnaise* , or heavy mayo
  • 1 tablespoon white miso paste
  • 1 teaspoon mirin
  • ½ teaspoon hondashi (optional)


  • Grab a small mixing bowl and add the mayonnaise, miso paste, mirin and hondashi (if using). Stir until well combined.
  • Store in an airtight container and refrigerate for up to 5 days.


  • I adore the combination of miso paste and Japanese kewpie mayonnaise, but you can use any heavy mayonnaise. Add half a teaspoon of hondashi powder to your plain mayo to add a savoury umami flavour. (Hondashi is not suitable for vegetarians.)
  • The white miso paste gives this miso mayo a mild miso flavour. Use red miso paste for a more intense umami flavour, or double the white miso paste.
