Duchess Potatoes

Dress up your holiday table with duchess potatoes, soft buttery swirls made from simple ingredients you likely already have. They bake up golden with crisp edges, pair with almost anything, and add an easy, elevated touch to any meal.

What Are Duchess Potatoes?

Duchess potatoes (AKA pommes duchesse) are a classic French dish made from buttery mashed potatoes mixed with egg yolks and baked into decorative swirls until lightly crisp on the outside and pillowy soft inside.

Flavor: Similar to twice-baked potatoes, Duchess potatoes are rich and buttery with a hint of nutmeg and lightly crisp edges.
Tools: A star piping tip gives the classic ridges that make this a fancy potato side dish. No pastry bag? A freezer bag with a corner snipped off works too (with or without the tip).
Make Ahead Tip: Bake or air fry the potatoes ahead, or make the entire mixture up to 2 days in advance.
Serving Suggestions: They make a beautiful holiday side to pair with roasted beef, ham, or weeknight chicken.
Freezing: Freeze unbaked swirls and bake straight from frozen for easy hosting.

Ingredients

Russet Potatoes: Russets are starchy and fluffy and hold their shape, making them perfect for this recipe. Baking instead of boiling will keep the moisture low for perfect piping.
Butter: Adds richness and helps the potatoes brown. Make sure it’s softened to room temperature so it blends more easily.
Seasonings: Nutmeg adds a warm, cozy note that makes creamy dishes even better, but a little goes a long way! Salt and pepper bring out the rich, buttery taste even more.
Eggs: The yolks create richness and help bind the mixture so the swirls stand up tall, while the whites are brushed on top for a golden, crisp finish.
Variations: Swap nutmeg for a pinch of garlic powder or white pepper for subtle savory notes. Stir in finely grated Parmesan cheese or roasted garlic for a more intense savory version. Add chopped fresh herbs (parsley, chives, thyme) for a fresh flavor boost.

PRO POTATO TIP: Save the potato skins from making duchess potatoes to turn into crispy, delicious potato skins.

How to Make Duchess Potatoes

Bake, scoop out, and mash the potatoes.
Stir in the remaining ingredients and pipe onto a parchment-lined baking sheet.
Brush with egg whites and bake until golden and crisp at the edges.

Using a potato ricer or food mill to create extra-smooth potatoes that pipe cleanly without lumps or clogging the tip.
Using baked potatoes instead of boiled ones gives the lightest, driest texture, helping them hold their shape beautifully when piped.
Let potatoes cool slightly before adding yolks so they don’t turn into scrambled eggs when added.
Keep the swirls around the same height so they bake evenly.
If the mixture feels too soft, chill it briefly to firm up before piping

Storage & Leftovers

Refrigerate unbaked or baked duchess potatoes in an airtight container for up to 4 days. Or freeze unbaked swirls on a tray until solid, then store in a freezer bag for up to 3 months.

Reheat baked leftovers in a hot oven or air fryer to restore their crisp edges. Or bake from frozen at 425°F for 15 to 20 minutes.

Prep Time 10 minutes

Cook Time 1 hour

Total Time 1 hour 10 minutes

Preheat oven to 425°F. Wash the outside of the potatoes and poke the skins all over with a fork. Place in the oven and bake until they are soft inside, about 50-60 minutes or until tender.
Allow the potatoes to cool and cut in half. Scoop out the middle and place in a bowl. Allow the potatoes to cool slightly.
Mash the potatoes until very smooth or use a ricer to rice the potatoes. Once smooth, add butter, nutmeg, and salt and pepper to taste. Stir in egg yolks.
Place the potato mixture into a piping bag with a star tip. Pipe mounds of potatoes about 2 inches wide and 1 ½ inches tall onto a parchment-lined pan. It’s okay if the sizes vary a little bit.
Whisk the egg whites with a fork until they’re slightly foamy. Brush the egg whites over piped potatoes very gently and bake 10-15 minutes or until golden.
Garnish with fresh herbs if desired.

Potatoes & Prep

Potatoes can be boiled but must be very well drained. If there is too much moisture, the potatoes won’t hold their shape as well.
Mash the potatoes very well, a potato ricer makes the perfect texture for this recipe.
If you don’t have piping bags, snip off the corner of a freezer bag and insert a piping tip if you’d like.

Make Ahead

These can be prepared up to 2 days ahead, covered, and refrigerated before baking.
Duchess potatoes can also be frozen before baking. Freeze them on the baking sheet, and then transfer them into a freezer bag. Bake from frozen for 15-20 minutes or until heated through.

Leftovers
Refrigerate leftovers for up to 4 days, or freeze for up to 3 months. Re-crisp in the oven or air fryer.
