Ingredients

  • 2 pounds Russet or Yukon Gold potatoes
  • 1/4 cup unsalted butter divided
  • 1/4 cup heavy cream
  • 1/4 cup grated Parmesan cheese
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 3 large egg yolks
  • Fresh chopped chives or parsley for garnish
  • 1 tablespoon sea salt for garnish

Instructions

Prepare the Potatoes:

  • Peel and chop the potatoes. Transfer them to a large pot and cover with cold water. Add a generous pinch of salt.
  • Bring to a boil over medium-high heat and cook for 15-20 minutes, or until the potatoes are fork-tender.

Preheat the Oven:

  • Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper.

Prepare Butter and Cream:

  • While the potatoes are cooking, melt the butter in a small bowl using the microwave. Warm the heavy cream in another microwave-safe bowl. Set both aside.

Mash the Potatoes:

  • Drain the cooked potatoes thoroughly and return them to the pot over low heat to evaporate excess moisture.
  • Mash the potatoes with a potato ricer or masher until smooth and lump-free.

Mix the Ingredients:

  • Add 2 tablespoons of the melted butter, the warm heavy cream, Parmesan cheese, salt, and pepper to the mashed potatoes. Mix until fully incorporated.
  • Stir in the egg yolks until the mixture is smooth and well combined.

Pipe the Potatoes:

  • Transfer the mashed potato mixture to a piping bag fitted with a large star tip to create decorative swirls.
  • Pipe the mixture into small mounds (or rosettes) onto the prepared baking sheet, spacing them about 1 inch apart.

Bake:

  • Brush the potato mounds with the remaining melted butter.
  • Bake for 15-20 minutes, or until the edges are golden brown and slightly crispy.

Garnish and Serve:

  • Remove from the oven and garnish with fresh chopped chives or parsley.
  • Sprinkle sea salt on top for extra flavor. Serve immediately and enjoy!

Notes

Potato Choice: Russet potatoes create a fluffier texture, while Yukon Gold potatoes offer a creamier, richer result. Either option works beautifully.
Make-Ahead Tip: Pipe the potatoes onto the baking sheet, cover, and refrigerate for up to a day. When ready to serve, brush with melted butter and bake.
Serving Suggestions: Pair with roasted meats, poultry, or fish for a stunning side dish.
