Duchess Potatoes are elegant piped mashed potato swirls that are crispy on the outside and creamy on the inside. Rich with butter and egg yolks, they make a beautiful and delicious side dish perfect for special occasions or dinner parties.

Ingredients

  • 2 lbs Russet or Yukon gold potatoes, peeled and chopped
  • 4 tbsp unsalted butter
  • 1/4 cup heavy cream or milk
  • 3 large egg yolks
  • 1 tsp salt
  • 1/4 tsp black pepper
  • Pinch of nutmeg (optional)
  • Optional: melted butter for brushing, chopped herbs for garnish

Instructions

  1. Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper.
  2. Boil potatoes in salted water until fork-tender, about 15–20 minutes. Drain and let steam dry for a few minutes.
  3. Mash the potatoes until smooth. Mix in butter, cream, salt, pepper, and nutmeg if using.
  4. Let the mash cool slightly, then stir in the egg yolks until fully combined.
  5. Transfer mixture to a piping bag fitted with a large star tip.
  6. Pipe swirls or rosettes onto the prepared baking sheet.
  7. Brush tops with melted butter.
  8. Bake for 18–22 minutes until golden brown and crisp on the edges.

Notes

  • Add grated Parmesan or Gruyère cheese for extra flavor.
  • Mix in roasted garlic or fresh herbs like thyme or chives.
  • Make smaller bites for appetizer-style servings.
  • Don’t microwave leftovers—reheat in oven for best texture.
  • Pipe and freeze unbaked for easy make-ahead preparation.
