Duchess Potatoes

Duchess Potatoes transform ordinary mashed potatoes into an elegant side dish with their beautiful piped swirls and golden-brown exterior. This French classic combines creamy potato interiors with slightly crisp edges, creating a perfect texture contrast that makes them special enough for holiday tables or dinner parties. The simple ingredients belie the impressive presentation, proving that sometimes the most basic foods can become the most memorable with just a bit of technique.

I first made these for a Christmas dinner years ago, and my family still requests them for special occasions. The look on guests' faces when they see these beautifully piped swirls is always worth the extra few minutes with the piping bag.

Ingredients

• 2 pounds Yukon Gold potatoes: Perfect balance of starch and moisture for a buttery texture.
• 1/3 cup heavy whipping cream: Adds richness while keeping the potatoes silky.
• 3 tablespoons unsalted butter: Essential for flavor and crispiness.
• 1 teaspoon salt: Enhances flavor without overpowering.
• 4 egg yolks: Provide structure to hold their shape.
• 2 tablespoons unsalted butter for brushing: Creates the golden-brown crust.

Step-by-Step Instructions

Prepare and Boil the Potatoes:

Peel and quarter Yukon Golds, then place in a pot of cold salted water. Bring to a gentle boil and cook until fork-tender, about 15-20 minutes.

Drain and Dry:

Drain well and return to the hot pot for 1 minute, allowing excess moisture to evaporate.

Mash Smoothly:

Pass through a ricer or food mill for the smoothest texture. Avoid overworking.

Incorporate Butter and Cream:

Stir in butter until melted, then gradually mix in warm cream.

Add the Egg Yolks:

Let the mixture cool slightly, then fold in whisked egg yolks gently.

Prepare for Piping:

Transfer to a piping bag with a large star tip. Chill for 15-20 minutes if too soft.

Pipe the Potatoes:

On a parchment-lined baking sheet, pipe 2-3 inch swirls, leaving space between them.

Brush with Butter:

Lightly brush with melted butter for a golden finish.

Bake to Perfection:

Bake at 425°F for 15-20 minutes until golden brown.

Rest Briefly:

Let rest for 2-3 minutes before serving.

I've experimented with various potato varieties over the years, and nothing beats Yukon Golds for this recipe. My grandmother used to make these with russets, but I found they needed more cream and butter to achieve the same silky texture.

Perfect Pairings

Duchess potatoes pair beautifully with rich meats like beef tenderloin, soaking up flavorful juices. Their golden swirls also add elegance to holiday meals, making them a stunning alternative to mashed potatoes. They also look beautiful placed around a turkey platter for a dramatic effect.

Make-Ahead Magic

You can pipe these potatoes onto baking sheets up to 24 hours ahead, keeping them covered in the refrigerator. Before baking, brush with melted butter. For longer storage, freeze unbaked swirls, then bake directly from frozen, adding a few extra minutes.

Temperature Matters

Using room-temperature butter and warm cream ensures smooth incorporation. Letting the mixture cool slightly before adding egg yolks prevents them from scrambling. These small temperature details lead to a perfect final result.

I've been making these duchess potatoes for nearly twenty years now, and they never fail to impress. What I love most about them is how they transform humble potatoes into something that looks like it came from a fine dining restaurant. Even when I've had kitchen disasters with other dishes, these potatoes have consistently been showstoppers that distract from any other culinary mishaps!
