Keyword: Duchess Potato Recipe, Pommes de Terre Duchesse
Servings: 6 to 8 servings
  • 7 cups potatoes (Yukon Gold or Russet), peeled and cut into 1 1/2-inch chunks*
  • 3/4 cup half & half cream, warmed and divided
  • 7 tablespoons butter, room temperature
  • 2 egg yolks
  • 1 1/2 teaspoons salt
  1. In large saucepan, add cut-up potatoes and just enough cold water until potatoes are covered; bring to a boil.  Reduce heat to medium; cover and let simmer 15 to 20 minutes or until potatoes are tender when pierced with a fork.  Potatoes are done when the internal temperature registers approximately 200 degrees F. on your cooking thermometer.

  2. When the potatoes are cooked, remove from heat and immediately drain potatoes thoroughly in a colander.  Return to saucepan; heat over medium-low heat approximately 1 to 2 minutes to dry potatoes, stirring occasionally.  

  3. NOTE:  Boiled potatoes left in water will start to jellify and may even increase in volume, becoming swollen and watery.  That is why it is important to let the potatoes drain for a couple of minutes in a colander immediately after they are cooked.

  4. Mash potatoes with a potato masher or ricer (do not use your electric mixer) until they are smooth and free of chunks. For the smoothest, most uniform texture, use a food mill or ricer to mash the potatoes.

  5. Add 1/2 cup half and half cream, butter, egg yolks, and salt.  Mix thoroughly to blend.  You do not want the mashed potatoes to be too soft or they will not hold their shape when baked.  Slowly add remaining 1/4 cup half and half cream to the potatoes (you may not need to use all the half and half cream - the potatoes should be stiff).

  6. Either spoon or pipe onto parchment-lined baking sheets leaving 2 inches between mounds.

  7. To Pipe, place a large star tip in pastry bag and fill bag with potato mixture.  Pipe circular or rectangular shapes onto parchment-lined baking sheet.  Continue piping until baking sheet is full.  When piping, start from the outside and slowly work your way to the middle, overlapping a little each time around to create the mound and point in the middle. 

  8. If you do not have a pastry bag, cut a diagonal slit one inch from the point on corner of plastic bag. Carefully spoon the potato mixture into bag. Squeeze the air out of bag as your seal. to pipe the mixture, hold the filled bag perpendicular to the baking sheet, then force the potato mixture through the top by squeezing the end of the bag with your writing hand and supporting the bag with your other hand.

  9. Alternate designs: (1) Pipe into decorative mounds in lightly greased muffin cups. (2) Shape into rosettes.

  10. Some chefs simply shape the mashed potatoes into a mound with a spoon and then use a fork or similar instrument to shape the edges. 

  11. To bake later: Loosely cover with plastic wrap and refrigerate until ready to use. Recipe can be prepared to this point, covered and refrigerated, up to 24 hours. Remove plastic wrap and spray lightly with vegetable oil spray before baking.

  12. When ready to bake, preheat oven to 450 degrees F. Place baking sheet on middle rack in oven. Bake for 15 to 20 minutes or until tops are lightly browned. NOTE: The size of the duchess potatoes and the desired level of crispiness on the edges will indicate the amount of time that they should be baked. 

Recipe Notes

* Choose potatoes of the same size so that they cook evenly.
