Duchess Potatoes


  • Author: Luna
  • Total Time: 45 minutes
  • Yield: 6 servings 1x

Ingredients

Scale
  • 2 lbs russet or Yukon Gold potatoes, peeled and chopped
  • 4 tbsp unsalted butter, softened
  • ½ cup heavy cream
  • 3 large egg yolks
  • ½ tsp salt
  • ¼ tsp black pepper
  • ¼ tsp ground nutmeg
  • ½ cup Parmesan cheese (optional, for extra richness)
  • 1 tbsp fresh chives or parsley, finely chopped (optional, for garnish)
  • 1 egg yolk + 1 tbsp milk (for egg wash)

Instructions

Step 1: Boil the Potatoes

Place the chopped potatoes in a large pot and cover them with cold, salted water. Bring to a boil and cook for about 15 minutes or until the potatoes are fork-tender. Drain and return them to the pot to let excess moisture evaporate.

Step 2: Mash the Potatoes

Using a potato masher or ricer, mash the potatoes until smooth. Avoid using a blender or food processor, as it can make the potatoes gummy.

Step 3: Add the Butter and Cream

Stir in the butter, heavy cream, salt, pepper, and nutmeg while the potatoes are still warm. Mix until fully incorporated and smooth.

Step 4: Incorporate the Egg Yolks

Let the mashed potatoes cool slightly, then mix in the egg yolks one at a time. If using Parmesan cheese, add it now for extra flavor. The mixture should be rich and creamy.

Step 5: Pipe the Potatoes

Preheat your oven to 400°F (200°C). Transfer the potato mixture into a piping bag fitted with a large star tip. Pipe swirls onto a parchment-lined baking sheet, spacing them about an inch apart.

Step 6: Brush with Egg Wash

In a small bowl, mix the extra egg yolk with milk. Lightly brush this mixture over each potato swirl for a golden, crispy finish.

Step 7: Bake Until Golden

Bake for 20–25 minutes or until the edges are golden brown and slightly crisp.

Step 8: Serve and Enjoy!

Garnish with fresh chives or parsley and serve warm.
