Duchess potatoes (pomme duchesse) with sweet potato – Vegan recipe

Updatet on:

Yummy duchess potatoes or pomme Duchesse 🙂 It’s a fancy way to serve potatoes, they look like a curly tower.

Duchess potatoes a holiday potato

For those who do not know: Duchess potatoes is a potato preparation that is still a bit lagging behind in terms of popularity with the fries and the potato croquette. We at least ate them only on special occasions. For example Christmas, New Year and February 26, 1991 … the day our freezer broke down and we had to eat the storage bag Duchess potatoes.

But seriously: that holiday reputation of this dish is of course mainly related to the typical shape. After all, the basic preparation, an ordinary mashed potato, is put in a piping bag to spray a nice turret. That looks more decorative on a plate than a jelly mashed potatoes. Most people think the Duchess Potatoes is a ‘potato croquette with pretension’. To express it as playfully as possible.

Unfairly if you ask me.

Duchess Potatoes vs croquettes

First of all, you can’t compare the Duchess potatoes with a potato croquette. There are no bread-crumbs around and the taste is far from the same. And unlike French fries, you don’t have to fry them. Anyway, you can also prepare fries in the oven, but that is – in my humble opinion – a lot less delicious. Pommes Duchesse just begs for an oven preparation.

To top it all off, the Duchess potatoes are also much faster to prepare than the other two. Because of this characteristic shape, you may fear that it requires a lot of work, but nothing is less true. You just have to make good mashed potatoes and put it in a piping bag. The creation of these turrets then goes super fast and very easy. You don’t have to be Jamie Oliver for that.

In short: are you a potato lover and do you want something different than cooked or mashed … Duchess potatoes are worth a try!

Orange and sweet?

Having said this: although my recipe does not contain any eggs (again no idea why people use it in the traditional recipe) or cream, Duchess potatoes are not very original either. That’s why I wondered how they would taste with sweet potato.

If that idea had been bad, you would never have read it here. So you feel the good news coming … this is su-per-delicious!
And it looks very colorful 🙂

So here it comes the recipe for the ‘Duchess potatoes with Sweet Potato’!

Or wait … first a good tip; do not make the duchess too big when you pipe them on a baking tray. The bigger they are, the harder to bake. Of course, too small is not good either. The ideal is a diameter of about 4 cm and a ditto height.

However, you do not have to add a yardstick 😉

This recipe is good for about 34 – 36 pieces. Normally sufficient for 6 people.
Enjoy it!

Duchesse potatoes (pomme duchess) with sweet potato - Vegan recipe


  • 1 kg potatoes
  • 500 gram sweet potatoes
  • Black pepper, freshly ground - to taste
  • Nutmeg, freshly ground - to taste
  • 0.5 tsp salt (you may also omit of course)


  1. Peeled and cut the potatoes. Put in a large pot of lightly salted water and bring to boil. After 5 minutes add the sweet potato pieces and continue cooking until both are well cooked. Usually, that is another 15 minutes.
  2. Pour the potatoes into a colander and let drain and evaporate. Put them back in the pot and puree them with the help of a potato masher. Add (optional) the salt and season to taste with pepper and nutmeg. Stamp again well and let cool to room temperature.
  3. In the meantime, preheat the oven to 200 ° C / 390 ° F. Line a baking tray with parchment paper.
  4. Put the mashed potatoes in a piping bag with a nozzle. Pipe the Duchess potatoes in rows on the baking paper. Keep approximately 2 cm distance between each turret.
  5. Bake the Duchesse potatoes for 15-20 minutes in the preheated oven. When the outside begins to form a crust, they are ready. Eat them immediately after baking. No, not on your own 😉

Tip: you can experiment with the size of the nozzle. Of course, every size gives a different effect, the result is always just nice. I used a nozzle with an opening of about 5 mm.
