  • 2 1/2 lbs Yukon gold potatoes peeled and diced
  • Salt and freshly ground black pepper
  • 6 tablespoons unsalted butter divided
  • 4 cloves garlic finely minced
  • 1/4 teaspoon nutmeg
  • 1/4 cup heavy cream
  • 1/2 cup parmesan cheese finely shredded
  • 3 large egg yolks
  • 1 teaspoon fresh parsley minced - for garnish
  • 1 tablespoon grated parmesan for serving


  • Preheat oven to 425 degrees F.
  • Line a baking sheet with parchment paper, grease it with 1 tablespoon butter or oil and set it aside.
  • Add potatoes to a large pot and cover with cold water, over medium heat. Season with some salt and bring it to a boil.
  • Reduce heat to medium-low, cover the pot with a lid and simmer until the potatoes are very tender about 15 - 20 minutes. Transfer to a colander and drain potatoes very well.
  • Add 3 tablespoons of butter to a small saucepan and melt it over medium heat, once melted add garlic and saute until lightly golden, about 1 - 2 minutes.
  • Remove saucepan from heat, and stir in the half and half then pour the mixture into a small bowl, this is to avoid burning the garlic, set aside.
  • Transfer the drained potatoes into a large mixing bowl. Mash them until there are no longer any lumps.
  • Stir in parmesan cheese and the butter garlic mixture. Add nutmeg and season them with salt and pepper.
  • Let the mixture cool a few minutes, and then quickly stir in the egg yolks one at a time using a wooden spoon.
  • If the mixture is very thick, add 1 tablespoon half and half.
  • Transfer mixture to a large piping bag fitted with a large star tip. Pipe the potatoes onto the prepared baking sheet, make 12-16 mounds spaced evenly apart, being about 2 1/2-inches wide by 2 1/2-inches tall.
  • Gently brush them with the remaining 2 tablespoons of melted butter.
  • Bake in the preheated oven until golden brown, about 17-20 minutes.
  • Serve immediately garnished with parsley and grated parmesan cheese.
