2 lbs Yukon gold potatoes, about 9 small potatoes, peeled and roughly chopped

¼ cup miso paste, preferably white or sweet miso

¾ cup heavy cream

4 tbsp butter, plus more for topping

34 garlic cloves, minced

Kosher salt, to taste

Cracked black pepper, to taste


  1. Boil potatoes: Add potatoes to a large pot and fill with water until the potatoes are covered by 1 inch of water. Bring to a boil and boil potatoes for 15-20 minutes, or until fork tender. 
  2. Mash potatoes: Drain the potatoes and return to the pot. Mash with a potato masher or a hand mixer until desired consistency is reached.
  3. Stir in miso, cream and butter: Add miso paste, heavy cream, butter and garlic and mix together until smooth and butter is melted. Season with salt and pepper. Taste test and adjust seasoning to your liking.


Make-Ahead: Store mashed potatoes in an airtight container in the fridge for up to 3 days.

Reheat: Set up a double boiler – place potatoes in a heat-resistant bowl over a pot of simmering water, making sure the bottom of the bowl is not touching the water. Stir occasionally, until warmed through.
