Simple to make and elegant to serve, these Duchess Potatoes freeze beautifully for a make-ahead side dish for your holiday or any time feast.
I used the following ingredients for the Duchess Potatoes: Russet potatoes, unsalted butter, heavy cream, egg yolks, salt, pepper, and nutmeg.
Making the Duchess Potatoes
In the past when I’ve made these, I’ve peeled, sliced and boiled the potatoes. However, doing it this way introduces a lot of water into the potatoes, impacting their final consistency. This time, I thought – why not just microwave the whole potatoes, which would not only allow for the liquid to evaporate, but also make it super easy to remove the skin? This worked like a charm! First, I pricked the potatoes all over with a fork. Then I microwaved them for 18 minutes on high, turning them over twice.
After 18 minutes, the potatoes were perfectly cooked. I let them sit for about 10 minutes to cool a bit before scooping them into my ricer.
Next, I riced the potatoes in batches into a large bowl.
I added the butter to the hot potatoes, along with the salt, pepper, and nutmeg. Finally, I stirred the potatoes well with a wooden spoon, and tasted the mixture to see if I needed to add additional salt. Then I added the egg yolks and cream, and continued stirring the mixture until everything was well incorporated.
I fitted a piping bag with a 1-M star tip and placed the bag into a tall glass. And using a large ice cream scoop, added some of the mixture to the bag. This was a trick that I learned from Susan, and it makes it much easier to fill piping bags!
I piped a 3-inch circle onto a parchment lined baking sheet, and built it upward to produce the classic shape of the Duchess Potatoes. I repeated this for the remaining mixture, ending up with 12 Duchess potatoes.
At this point, the Duchess Potatoes can be frozen for later use, or brushed with egg wash and baked at 400° F for about 30 minutes, until they are lightly brown. I chose to freeze half of the Duchess Potatoes and use the rest for tonight’s dinner.
After 30 minutes, the Duchess Potatoes were lightly brown and absolutely delicious. From past experience, the frozen ones will be equally delicious. Yum!
To freeze, pipe Duchess Potatoes on parchment paper on a baking sheet. Place baking sheet in freezer until Duchess Potatoes are frozen. Transfer to Ziploc bag, seal, and place in freezer. To heat, place the frozen Duchess Potatoes on a baking sheet, brush with egg wash, and bake in a preheated 400°F oven for 35 minutes or until lightly browned.
