Duchess potatoes are an easy, make ahead holiday recipe that will impress any dinner guest.  These low carb morsels are baked in the oven and are simple to make.  Serve these to your family or for a crowd—either way they are sure to please!



  • 2 pounds russet potatoes (about 5 medium potatoes)
  • 1/4 teaspoon salt
  • 4 large eggs, yolks
  • 4 tablespoons salted butter
  • 1/2 cup heavy whipping cream
  • 1/2 teaspoon salt
  • 1/4 teaspoon white pepper
  • 1/8 teaspoon garlic powder
  • 1/8 teaspoon ground nutmeg
  • 1 egg white


Making the Potato Mixture

  1. Wash, peel, and cube the potatoes and cover with cold salted water.  Bring to a boil, then simmer for 12 to 15 minutes or until fork tender.  Drain and dump into a large bowl.  Let the potatoes release steam for a few minutes as it will help get rid of extra moisture.
  2. Add a few potatoes at a time to the potato ricer.  Squeeze the ricer to press the potatoes out through the bottom.  Use a knife to scrape the potatoes off the ricer and into the bowl.  Repeat this process until all the potatoes are done.  (Using a potato ricer will make the potatoes lump free and fluffy.  If you don’t have a potato ricer, mash them until all the lumps are out.)
  3. Separate the egg whites from the yolks.  Place the yolks on top of the potatoes and the whites in a small bowl.
  4. While the potatoes are still warm, add the butter, heavy cream, salt, white pepper, garlic powder, and nutmeg.  Stir until well combined.  Adjust seasonings to taste.

Piping the Potatoes

  1. Line two large cookie sheets with parchment paper.
  2. Snip the corner off a freezer bag and insert a 1/2-inch star tip into the corner.  Put the piping bag in a tall, wide-mouthed glass or vase and pull the sides of the bag over the glass to make it easier to put the filling in it.
  3. Fill the bag half full, making sure the tip is properly in place.  Twist the top of the piping bag until tight.  Pipe the potato mixture in spirals on the prepared cookie sheets, making sure to space them evenly.  Pipe at a consistent speed, and use even pressure.
  4. Chill the potatoes for 15 minutes in the freezer or 30 minutes in the fridge so the potatoes can firm up before applying the egg white.

Baking the Potatoes

  1. Preheat the oven to 400 F.  Once the potatoes have chilled, whisk the egg white and carefully brush the duchess potatoes with it.
  2. Bake two trays at a time, each on a separate rack for 15 minutes.  Switch the top and bottom trays and rotate for even cooking, then cook for another 10 minutes.
  3. Allow the duchess potatoes to cool on the tray for 5 minutes before transferring to a serving platter.  Serve warm.


  • Before you pipe all the potatoes, make a few practice ones on a cutting board.  When you are done practicing, just add them back to the piping bag.
