Duchess potatoes are a fancy way to enjoy mashed potatoes! They are smooth, creamy, and shaped into lovely little mounds that are baked to golden perfection.
These potatoes are great for special occasions, and they add a touch of class to any plate. Trust me, when you serve them, everyone will ask for more! 😄
I love making Duchess potatoes when I want to impress my guests. Just whip up some mashed potatoes, pipe them out, and bake. Simple and oh-so-elegant!
Key Ingredients & Substitutions
Potatoes: Russet or Yukon gold potatoes work best for their creamy texture. If you’re in a pinch, you could use red potatoes, but the texture won’t be as fluffy.
Butter: Unsalted butter is ideal to control the salt content. If you’re looking for a dairy-free option, try using vegan butter or olive oil—just keep the flavor in mind!
Cream: Heavy cream makes the potatoes rich, but you can substitute with whole milk or even a non-dairy milk like almond or oat milk for a lighter version.
Egg Yolks: The egg yolks give richness and help with binding. If you’re avoiding eggs, consider using a tablespoon of cornstarch mixed with a bit of water as a binder.
How Do You Achieve the Perfect Consistency for Duchess Potatoes?
The key to smooth Duchess potatoes is all in the mashing! After boiling, make sure you drain them well—moisture can lead to lumpy potatoes.
- Use a traditional potato masher or a food mill for a super smooth texture.
- Let the mashed potatoes cool slightly before mixing in other ingredients. This prevents the butter and cream from separating.
- Mix gently! Over-mixing can lead to gummy potatoes.
Piping the mashed potatoes creates those cute rosettes. Ensure the mixture is smooth and not too thick—this will help in achieving beautiful shapes on the baking sheet. Enjoy making these delightful Duchess Potatoes!

Ingredients You’ll Need:
- 2 pounds (900g) russet or Yukon gold potatoes, peeled and cut into chunks
- 4 tablespoons unsalted butter, softened
- 1/3 cup heavy cream (or whole milk)
- 2 large egg yolks
- 1 teaspoon salt, or to taste
- 1/2 teaspoon white pepper, or to taste

How Much Time Will You Need?
This recipe takes about 30 minutes to prepare and 15-20 minutes to bake, totaling around 45-50 minutes. It’s a quick way to create an elegant side dish that always impresses!
Step-by-Step Instructions:
1. Preheat the Oven:
Start by preheating your oven to 400°F (200°C). This is important because you want your Duchess potatoes to turn out perfectly crispy and golden on the outside!
2. Prepare the Potatoes:
Put the peeled and chopped potatoes in a large pot and cover them with cold water. Add a pinch of salt to enhance the flavor. This is the first step to getting those deliciously seasoned potatoes!
3. Cook the Potatoes:
Bring the water to a boil over medium-high heat. Once boiling, reduce the heat and let the potatoes simmer until they are tender and can be easily pierced with a fork—this usually takes about 15-20 minutes.
4. Mash the Potatoes:
After cooking, drain the potatoes thoroughly and return them to the pot or a large bowl. Mash them well until they are smooth and creamy—this is key to achieving that light, fluffy texture!
5. Mix in the Ingredients:
Add the softened butter to the mashed potatoes and mix until it’s fully incorporated. Then, stir in the heavy cream (or milk) until your mash is creamy and perfect.
6. Add Egg Yolks and Seasoning:
Add the egg yolks, salt, white pepper, and a pinch of nutmeg (if you like!). Mix everything until it is well combined into a lovely, rich mash.
7. Pipe the Potato Mixture:
Get your piping bag fitted with a large star tip and fill it with the mashed potato mixture. This is where the fun begins!
8. Shape the Potatoes:
Pipe the mixture onto the prepared baking sheet in small mounds or rosettes, about 2 inches wide and tall. They should look fancy and delightful!
9. Bake for Crispiness:
Place the baking sheet in the oven and bake for 15-20 minutes, or until the edges are a beautiful golden brown and the tops are slightly crispy. Your kitchen will smell amazing!
10. Garnish and Serve:
Once baked, remove the Duchess potatoes from the oven. Feel free to garnish them with fresh thyme or parsley for an extra touch. Serve warm and enjoy these elegant potato delights!
These Duchess potatoes are sure to wow your family and friends at your next gathering!
Can I Use Different Types of Potatoes for Duchess Potatoes?
Yes, you can use other types of potatoes, but Russet or Yukon gold are the best for a creamy texture. Red potatoes can work in a pinch, but they may yield a denser mash.
Can I Make Duchess Potatoes Ahead of Time?
Absolutely! You can prepare the mashed potato mixture a day in advance. Just store it in the refrigerator, and then pipe and bake them just before serving for the best texture.
How Do I Store Leftover Duchess Potatoes?
Store any leftovers in an airtight container in the fridge for up to 3 days. To reheat, place them in a preheated oven at 350°F (175°C) for about 10-15 minutes, or until heated through and slightly crisped.
What Can I Use Instead of Egg Yolks?
If you’re avoiding eggs, you can substitute each egg yolk with 1 tablespoon of cornstarch mixed with a little water, which will help bind the potatoes without affecting the flavor too much!
