This recipe brings richness from butter, cream, and egg yolks, while a touch of Parmesan adds a lovely depth.

I first made these when I wanted to elevate a weeknight dinner and was amazed at how easy it was to get impressive results. Now they’re a go-to for holidays and special occasions in my house.
Ingredients
- Two pounds Russet or Yukon Gold potatoes: perfect for fluffy texture and smooth mash
- Quarter cup unsalted butter divided: provides richness use good quality butter for best flavor
- Quarter cup heavy cream: adds creaminess and helps the potatoes pipe beautifully
- Quarter cup grated Parmesan cheese: optional but recommended for added savoriness
- One teaspoon salt: to enhance the natural flavors
- Half teaspoon black pepper: for gentle seasoning
- Three large egg yolks: help bind the mixture and create a golden color when baked
- Fresh chopped chives or parsley: fresh herbs add color and brightness for garnish
- One tablespoon sea salt: sprinkled on top for crunch and flavor balance
Step-by-Step Instructions
- Soothe the Potatoes:
- Peel and chop the potatoes into even pieces so they cook evenly. Place them in a large pot and cover with cold water, adding a pinch of salt to flavor them as they cook. Boil over medium-high heat for 15 to 20 minutes until a fork easily slides through the potatoes.
- Prep Your Oven and Tools:
- Preheat your oven to 425 degrees Fahrenheit. Line a baking sheet with parchment paper to keep the potatoes from sticking and for easy cleanup.
- Warm the Dairy:
- Melt half of the butter in the microwave until liquid but not browned. Warm the heavy cream in a separate bowl to help the potatoes absorb fats smoothly.
- Mash and Mix:
- Drain the potatoes well and return them to the pot over low heat for about a minute. This step evaporates excess moisture, giving you fluffier results. Mash the potatoes until perfectly smooth then stir in the melted butter, warmed cream, Parmesan, salt, and pepper. Finally, gently fold in the egg yolks to enrich the mixture and help it hold its shape.
- Pipe the Potatoes:
- Transfer the mixture to a piping bag fitted with a star tip for that classic duchess look. Pipe small, decorative mounds onto your prepared baking sheet. Brush the tops with the remaining melted butter to encourage browning.
- Bake to Perfection:
- Put the potatoes in the oven and bake for 15 to 20 minutes or until they turn golden brown and develop a slightly crisp exterior. The contrast of creamy inside and crisp outside is what makes this dish irresistible.
- Garnish and Serve:
- Sprinkle with chopped chives or parsley and a light dusting of sea salt. Serve immediately while warm and fresh.

Storage Tips
Store leftover duchess potatoes in an airtight container in the fridge for up to three days. To reheat, place them in a 350-degree oven for about 10 minutes until warmed through and crisp on top. Avoid microwaving as it may make them soggy.

You can swap Parmesan for Gruyère or a sharp Cheddar if you want a different cheese flavor. Light cream can be replaced with whole milk plus a tablespoon of butter for a lighter version. If you cannot pipe the potatoes, spoon them into mounds and smooth slightly with a fork.
Serving Suggestions
These potatoes pair perfectly with roasted chicken, beef, or a festive holiday ham. They also work wonderfully alongside steamed green beans or a fresh leafy salad to balance the richness.
