Duchess potatoes are airy, piped swirls of creamy mashed goodness that look like they came straight out of a fancy bistro. They’re surprisingly easy to make, and they add a touch of elegance to any meal. Below is a snappy recipe I call “Herb-Infused Duchess Potatoes with Garlic-Parmesan Crisp,” guaranteed to bring warmth and a lovely hint of sophistication to your dinner table.

Ingredients
- 2 pounds potatoes, peeled and cubed
- 3 tablespoons unsalted butter
- ¼ cup heavy cream
- 1 teaspoon garlic powder (or 1 clove fresh garlic, minced)
- 1 teaspoon dried parsley or chives
- ¼ cup freshly grated Parmesan cheese
- 2 egg yolks, divided
- Salt and pepper to taste

Instructions
Begin by boiling the peeled, cubed potatoes in salted water until they’re fork-tender. Once done, drain them thoroughly and let them sit in the warm pot for a minute or two to steam off any excess moisture.
Mash the potatoes with butter, heavy cream, garlic powder, and herbs until the consistency is smooth. Stir in the Parmesan cheese, then fold in one egg yolk. Season generously with salt and pepper, and taste to adjust.

Preheat your oven to 400°F (200°C). Transfer the potato mixture to a piping bag fitted with a star tip (or use a resealable bag with a corner snipped). Pipe neat swirls onto a parchment-lined baking sheet, leaving a little space between each swirl. Create a quick egg wash by beating the remaining egg yolk with a splash of water, then lightly brush the tops of the potato swirls for a glossy finish.
Bake for about 15 to 20 minutes, or until the Duchess potatoes turn a light golden brown. If you like extra crunch, sprinkle a bit more Parmesan cheese on top under the broiler for a minute or so.

These Herb-Infused Duchess Potatoes are great for special occasions or whenever you crave a showstopping side that’s both pretty and comforting. They suit families who appreciate classic flavors, and anyone searching for a simple yet restaurant-worthy dish. Feel free to swap the Parmesan for cheddar or add a sprinkle of paprika for a pop of color. It’s a versatile recipe that can be easily adapted to personal dietary needs and tastes, making it one you’ll return to over and over again.
