  • 5 lbs yukon gold potatoes peeled and cubed
  • 6 cloves garlic peeled and smashed
  • kosher salt
  • 1 cup high-quality salted butter melted
  • 1 cup heavy whipping cream room temperature
  • 6 sprigs fresh thyme
  • 8 oz mascarpone cheese room temperature
  • black pepper to taste


  • Add cubed potatoes to a large pot and fill with cold water until potatoes are completely covered. Add the smashed garlic and thoroughly salt the water, then bring to a boil and cook for 20-30 minutes, or until potatoes are tender and smash easily.
  • While potatoes cook, add the melted butter to a medium-sized bowl and gently whisk in the heavy whipping cream. Add the thyme sprigs and let steep until ready to add to the mashed potatoes.
  • Drain the potatoes and add them to a mixer bowl fitted with the paddle attachment and beat on medium-low until nearly smooth. Remove the thyme from the butter-cream mixture and add to the mixing bowl. Beat on low until combined, then add the mascarpone and continue mixing until potatoes are smooth and silky. Season with a sprinkle of black pepper and serve!


  • If you can't locate mascarpone cheese, you can use creme fraiche, or even cream cheese, instead.
  • Swap the fresh thyme for fresh sage, or rosemary! Or use a combination of herbs!
  • Brown the butter before whisking in the cream and herbs for a delicious nutty flavor boost.
  • Yukon golds are the best potatoes for this recipe, but you can use russet potatoes if that's what you have on hand.
  • To reheat: spoon potatoes into a pot over low heat and add ½ cup heavy cream and 2-3 tablespoons of butter. Stir gently and occasionally until warmed through.
