If there’s one side dish that is sure to steal the show at any dinner, it’s these beautiful Duchess Potatoes! Crispy on the outside with a creamy, light interior, they are both sophisticated and delicious.
Also known as pommes duchesse, this fancy potato dish is often seen at top restaurants. Thankfully, they are easy to make at home, too.
Whip mashed potatoes with egg yolk, milk, and butter for the perfect consistency. Pipe similar-sized rosettes using a star tip and piping bag, and bake until perfectly golden. Serve at your next dinner party or holiday feast.
Ingredients for Duchess Potatoes
Please be sure to scroll down to the recipe card below for the complete details!
- Potatoes: Any potatoes that mash well (Yukon Gold or baking potatoes).
- Butter: Salted or unsalted.
- Milk: I use whole milk from cows.
- Egg: You’ll need one whole egg and three yolks (save the whites for an omelette).
- Seasoning: Add sea salt and pepper.
How to Make Duchess Potatoes
- Prepare the ingredients. Peel, dice, and boil the potatoes. Mash them with the ricer. Mix with the other ingredients.
- Pipe. Spoon the mixture into a piping bag. Pipe the potatoes onto the baking sheet. Brush with egg wash.
- Bake. 20-25 minutes until golden brown.
Tips for Success
- The potatoes are easiest to pipe if the mixture is still warm. Once it cools down, it will separate a bit.
- Be sure to pipe a full layer on top of a full layer, without any gaps, so the potatoes don’t collapse during baking.
- Don’t skip the egg wash, this gives the potatoes that warm, golden color.
Recipe Tip
I used a star tip and a regular freezer bag. If you don’t have a star tip, spoon similar-sized rosettes with a cookie scoop (or spoon), and gently work your way around the potato with a fork to mimic those sharp ridges.
Possible Variations
- Potatoes: You can swap for sweet potatoes.
- Butter: For the best creamy taste, use butter. Alternatively, use ghee, stock, or melted coconut oil.
- Milk: Opt for sour cream, Greek yogurt, heavy cream, half and half, buttermilk, or the cooking water from the potatoes.
- Egg yolk: There is no substitute that will give that fluffy texture we want. You could use less milk if you omit the egg and see how that works.
- Egg wash: Or melted butter.
- Add-ins: Try Parmesan, roasted garlic, or finely chopped fresh herbs for extra flavor.
- Piping bag: If you don’t have one, spoon the mixture into a freezer bag and trim a small hole in one corner.

Yes, you can make them the day before. After you pipe the duchess potatoes on a baking sheet, place the tray in the fridge. Cover them once they firm up. You may need to add a few minutes to the baking time.
Add more milk, a bit at a time, until the consistency is pipeable.
A potato ricer will give the best, fluffiest results. You can use a masher instead, but there might be lumps which can make it harder to pipe, but where there is a will, there is a way.
