  • Potato ricer
  • Sheet pans
  • Parchment paper
  • Large resealable bag or piping bag
  • Extra-large star piping tip


  • 3 pounds yukon gold potatoes peeled and diced into 1-inch cubes
  • 6 tablespoons unsalted butter, divided
  • 4 cloves garlic, finely minced
  • ¼ cup heavy cream plus more as needed
  • Salt and pepper to taste
  • ½ cup finely grated parmesan cheese plus more for sprinkling
  • 4 large egg yolks
  • Chives for garnish


  • Preheat oven to 425 degrees F. Line a large sheet pan (or 2 medium sheet pans) with parchment paper.
  • Boil potatoes in a large pot with water (enough to fully submerge potatoes) until tender, about 20 minutes. Drain and rinse with cold water.
  • Meanwhile, make the cream and butter mixture: in a small saucepan, melt 4 tablespoons of butter. Add garlic and saute until fragrant, about 1 minute. Add the heavy cream and warm it up. No need to bring to a boil. Set aside.
  • Press the potatoes through a potato ricer into a large bowl, or mash with a masher until there are no lumps. Add the cream and butter mixture and combine using a rubber spatula. Tip: I’d highly recommend using a potato ricer for fluffy and lump-free potatoes. That way, it will be easier to pipe. Using a masher can sometimes make it dense and leave lumps behind.
  • Mix in parmesan cheese, and season with salt and pepper to taste. Then, fold in the egg yolks with a rubber spatula until evenly combined. The mixture should be quite thick. If it's very dry, add some more heavy cream (warmed).
  • Set up an extra-large piping tip in the corner of a large ziploc or piping bag (with the corner snipped off). Fill half of the potato mixture into the bag and pipe onto the prepared sheet pan, placing them about 2 inches apart. Repeat with the remaining potato mixture. Note: if you overfill the bag, it will be a bit hard to pipe.
  • Carefully brush the potatoes with the remaining 2 tablespoons of butter, melted. Sprinkle with more grated parmesan.
  • Bake for 18-20 minutes, until golden brown and slightly puffed up. Tip: rotate the pans halfway through for even browning.
  • Garnish with chives and more cheese if desired. Enjoy!


  • Potatoes: Use yukon gold potatoes for best results. They have a deeper yellow color and hold up better than, for example, russet potatoes.
  • Use a potato ricer: Highly recommended. The potatoes will be fluffier and lump-free, making it much easier to pipe. If you don't have a potato ricer, you can use a masher, but it may turn out a bit denser with a few lumps.
  • Season to taste before adding the eggs. You can add more salt and pepper, or even additional spices, such as garlic powder, onion powder, or Italian seasoning.
  • Piping bag and piping tip: For best results, use an extra-large piping tip and a large piping bag. If you don't have a piping tip, you can still pipe through a bag and add a few swirls and designs using a fork.
  • Make-ahead and freezing: The best way to make these ahead is by freezing them. Follow directions through step 6 (up until piping onto a sheet pan). Then, freeze the sheet pans with the duchess potatoes. Once they have hardened, transfer to a freezer-friendly resealable bag and freeze for up to 1 month. When ready to serve, arrange on a sheet pan and brush with melted butter and sprinkle parmesan. Bake (frozen) at 425 degrees F for 18-20 minutes or until golden brown, as directed. They may take a few extra minutes.
Recommended equipment: potato ricer, sheet pans, parchment paper, piping bag, extra-large star piping tip.
