Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

2 pounds Russet or Yukon Gold potatoes
1/4 cup unsalted butter, divided
1/4 cup heavy cream
1/4 cup grated Parmesan cheese (optional)
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

Directions

Boil the Potatoes: Peel and chop the potatoes into uniform pieces. Place them in a large pot, cover with cold water, add a generous pinch of salt, and bring to a boil over medium-high heat. Cook for about 15-20 minutes until fork-tender.
Prepare the Mixture: Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper. While the potatoes are cooking, melt 2 tablespoons of butter in a small bowl in the microwave. Warm the heavy cream in a separate microwave-safe bowl. Set both aside.
Mash the Potatoes: Drain the cooked potatoes thoroughly and return them to the pot over low heat to help evaporate any excess moisture. Mash the potatoes using a potato ricer or masher until smooth and free of lumps.
Combine Ingredients: Add two tablespoons of the melted butter, the warm heavy cream, grated Parmesan (if using), salt, and pepper to the mashed potatoes. Mix well, then stir in the egg yolks until fully incorporated.
Pipe the Potatoes: Transfer the mashed potato mixture to a piping bag fitted with a large star tip. Pipe the potatoes into small mounds (or rosettes) onto the prepared baking sheet, spacing them about 1 inch apart.
Bake: Brush the piped potatoes with the remaining melted butter and bake for 15-20 minutes, or until the Duchess Potatoes are golden brown on the edges and slightly crispy.
Garnish and Serve: Remove from the oven and garnish with fresh chopped chives or parsley. Sprinkle sea salt over the top, serve immediately, and enjoy.
