This duchess potatoes recipe is a perfect pretty side dish for your holiday gathering — my sons call them Christmas potatoes because I make them yearly during the holidays! You can also make them ahead of time, which is really convenient during the busy festive season.

What You Need to Make this Recipe
Potatoes — peel and chop 2 pounds of potatoes. I used Yukon gold potatoes, but russet potatoes will work as well. Butter — you’ll need ¼ cup unsalted butter, melted and divided. If you only have salted butter on hand, use ⅛ teaspoon less salt than the recipe calls for. Heavy cream — Heavy cream adds richness and creaminess to the potatoes. You can substitute with half and half or whole milk, but heavy cream is my favorite option here. You only need 2 tablespoons, anyway! Spices — a little ground black pepper and a pinch of nutmeg add flavor and warmth to these fancy potatoes. If possible, use freshly grated nutmeg. The taste is far superior to the pre-ground kind. Egg yolks — egg yolks are a key ingredient in duchess potatoes as they prevent them from collapsing. Save the egg whites to whip up some meringue cookies or a classic gin fizz cocktail!
How to Make Duchess Potatoes
- Place the peeled, chopped potatoes in a large pot and cover them with cold water. Bring to a boil over high heat. Cook until the potatoes are very tender, which will take 15 to 20 minutes. Drain very well. You want to get rid of as much moisture as possible.
- Place the boiled potatoes in a ricer using the smallest holes. Squeeze directly into a large mixing bowl. If, like me, you don’t have a potato ricer, mash the potatoes in a large mixing bowl using a potato masher or run them through a food mill. Mash until very smooth and lump-free. For even smoother potatoes, press the mashed potatoes through a fine mesh sieve.
- Add 2 tablespoons of melted butter, the heavy cream, salt, pepper, and nutmeg to the potatoes and stir until well combined. Allow the mixture to cool for a few minutes.
- One by one, stir in the egg yolks until they’re blended with the potatoes.
- Line a large baking sheet with parchment paper. Transfer the egg and potato mixture to a large piping bag fitted with a large star tip. Carefully pipe the potatoes into 12 decorative swirls onto the prepared baking sheet. They should be about 2½ inches wide and about 2 inches tall. Space them as evenly as you can.
- Brush melted butter over the tops of each potato mound. Be quite gentle as the potato mounds are delicate. Bake the potatoes at 425°F for 20 minutes or until the edges are golden brown. Garnish them with chopped fresh parsley and serve immediately.
Pro Tips for Making this Recipe
Allow the potatoes to cool at room temperature for a few minutes before adding the egg yolks. This will ensure the egg yolks don’t scramble. Use a stencil. If you don’t want to eyeball the size of the potatoes as you pipe them and you want them to all be the same size, use a stencil to create 2½-inch circles on one side of the parchment paper, or trace around the rim of a small bowl. Then flip the parchment paper over and pipe the potatoes onto the stenciled circles. If you’re worried about them falling flat: You can chill the duchess potato mounds for about 20 minutes in the refrigerator to help them firm up before baking. I never chill mine and they always hold their shape, especially since they don’t contain a large amount of butter or cream, so I don’t consider this a necessary step. But, it’s also a helpful one if you want to prep a few steps ahead of time, and then bake them when you’re ready. Use an egg wash. You can brush the eggs with egg wash (1 egg beaten well with 1 teaspoon of water) instead of melted butter to achieve a deeper golden brown. Garnish with different fresh herbs. While I love the slightly peppery bite of fresh Italian parsley, you could chop up chives or rosemary instead. Garnish with Parmesan cheese. Grate a little Parmesan cheese over the top of the potatoes once they come out of the oven for a rich, cheesy flavor.
