Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

2 lbs russet potatoes, peeled and cubed
4 tbsp unsalted butter
1/2 cup heavy cream
2 egg yolks
1/3 cup grated Parmesan cheese (plus extra for topping)
Salt and black pepper, to taste
Pinch of ground nutmeg (optional)

Directions

Preheat oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a large pot, boil the peeled and cubed potatoes in salted water until fork-tender, about 15–20 minutes.
Drain the potatoes well and return them to the pot. Mash thoroughly until completely smooth (a potato ricer is ideal for the best texture).
Stir in the butter, heavy cream, egg yolks, Parmesan cheese, salt, black pepper, and nutmeg (if using). Mix until fully combined and creamy.
Transfer the potato mixture to a piping bag fitted with a large star tip.
Pipe even swirls of the mixture onto the prepared baking sheet, spacing them slightly apart.
Sprinkle a bit of additional grated Parmesan on top of each swirl.
Bake for 18–22 minutes, or until the edges are golden and the tops are lightly crisp.
Serve warm as an elegant side dish.

Storage/Reheating

Store leftover duchess potatoes in an airtight container in the refrigerator for up to 3 days.
To reheat, place them on a baking sheet and warm in a 350°F (175°C) oven for 10–15 minutes until heated through and slightly crisp. Avoid microwaving, as it may affect the texture.
They can also be frozen after baking. Let cool completely, then freeze on a baking sheet before transferring to a container. Reheat from frozen in the oven at 375°F (190°C) for 20–25 minutes.

FAQs

Can I make duchess potatoes ahead of time?

Yes, you can pipe and refrigerate the swirls up to 1 day in advance. Bake just before serving for the best texture.

Why do I need egg yolks in this recipe?

Egg yolks help bind the mixture and give the potatoes a rich texture and golden color during baking.

Can I use another type of potato?

Russet potatoes are preferred for their starchy texture, but Yukon Golds can be used for a slightly creamier version.

How do I make the swirls hold their shape?

Use a firm potato mixture and make sure the potatoes are well mashed and not overly moist. Let the mixture cool slightly before piping.

What piping tip is best?

A large star tip (such as Wilton 1M or Ateco 829) is ideal for creating the classic swirl pattern.

Can I add other vegetables to the mixture?

You can add small amounts of puréed carrots or sweet potatoes for a twist in flavor and color, but it may affect the firmness of the final shape.

Are duchess potatoes gluten-free?

Yes, as written, this recipe is naturally gluten-free. Always verify the cheese and other ingredients if cooking for someone with sensitivities.

Can I skip the nutmeg?

Absolutely. The nutmeg is optional and can be omitted or replaced with a dash of white pepper or garlic powder.

What do duchess potatoes pair well with?

They go beautifully with roast meats, poultry, or fish, and work well on holiday plates alongside dishes like beef tenderloin or lamb.

Can I freeze duchess potatoes before baking?

Yes, pipe them onto a tray, freeze until solid, and then store in a sealed container. Bake from frozen, adding 5–8 minutes to the baking time.
