Ingredients

  • Russet or Yukon gold potatoes: For a fluffy interior and smooth piping Choose firm potatoes without sprouts or green spots
  • Unsalted butter: Adds rich flavor and helps with browning Use high quality for best taste
  • Heavy cream: Makes the potatoes extra creamy Try for fresh heavy cream not half and half
  • Grated Parmesan cheese: Brings a subtle nutty flavor and a bit of tang Pick a block and grate it fresh for maximum flavor
  • Salt: Enhances every bite and balances the richness Use fine salt inside and flaky sea salt for the top if you have it
  • Black pepper: Gives just enough bite Use freshly ground for best flavor
  • Large egg yolks: Make the potatoes pipeable and add a gorgeous golden color Use room temperature eggs for easiest mixing
  • Fresh chopped chives or parsley: For a burst of color and fresh herby finish Always pick vibrant green and crisp herbs for garnish
  • Sea salt: For garnish gives each bite a salty crunch and rounds out the flavors

Step-by-Step Instructions

Peel and Boil the Potatoes:
Start by peeling your potatoes and chopping them into even pieces so they cook at the same rate Place them in a large pot and cover with cold water ensuring there is enough water to fully submerge Add a generous pinch of salt This brings out the potato flavor while boiling Bring the pot to a boil over medium high heat and let them cook for about 15 to 20 minutes Check by piercing a piece with a fork it should slip in easily when they are ready
Prep the Oven and Tools:
As the potatoes cook preheat your oven to four hundred twenty five degrees Fahrenheit Line a baking sheet with parchment paper so the potatoes will not stick Gather your piping bag and a large star tip If you do not have a bag use a zip top gallon bag with the corner snipped off
Warm the Dairy:
While you are waiting for the potatoes melt the butter in a microwave safe bowl and warm the cream separately Do not let the cream boil just get it warm to the touch Keeping both warm helps them blend evenly into the potatoes so they stay extra creamy
Dry and Mash the Potatoes:
Once the potatoes are tender drain them thoroughly then return them to the hot pot over low heat for a minute or two This step evaporates any water left behind and gives you fluffier potatoes Mash using a ricer or a traditional masher until no lumps remain
Mix in the Good Stuff:
Add half the melted butter the warm cream the grated Parmesan cheese salt and pepper Stir until smooth and creamy Wait until it is all well mixed then add the egg yolks and stir until fully combined The mixture should be soft enough to pipe but thick enough to hold its shape If it feels too stiff add a splash more cream
Pipe the Potatoes:
Spoon your mashed potato mixture into the piping bag fitted with the star tip Pipe small mounds or rosettes onto the lined baking sheet leaving about an inch between each These puff up a little in the oven so give them room
Brush and Bake:
Brush the tops of the potatoes with the remaining melted butter to help them crisp up in the oven Place the tray in your preheated oven Bake for fifteen to twenty minutes or until the edges of the Duchess potatoes are beautifully golden and just crispy
Garnish and Serve:
Take the tray out and sprinkle chopped chives or parsley over the tops Finish with a sprinkle of sea salt for that extra burst of flavor Serve immediately so everyone can enjoy them at their crispiest

Every time I pipe them I remember the first time my youngest niece insisted on helping and ended up making the most wobbly beautiful little potato towers She eats hers straight off the tray usually before dinner

Storage Tips

Cool any leftovers before packing them up so the edges stay as crisp as possible Store in a single layer in an airtight container in the fridge for up to three days They reheat best in a hot oven for ten minutes getting the tops crisp again and the centers soft

Ingredient Substitutions

If you are out of Parmesan try sharp cheddar Gruyere or pecorino for a different spin If you need to make it dairy free use a rich dairy free butter and unsweetened plain oat or soy cream Mash potatoes are flexible to what you have but Russets and Yukon golds really do give the best fluff

Serving Suggestions
