We often think of potatoes as the plain jane, trusty side dish, but this recipe elevates them to royalty status, the crowning glory of the potato canon. They're akin to twice-baked potatoes, but easier to make, and the end result is prettier, too. This duchess potatoes recipe is a French classic that captures elegance in simplicity.
Pommes Duchesse is also a lesson in contrasts. Crisp exteriors give way to velvety, butter-laden interiors. It's an indulgence, sure, but one that any self-respecting potato enthusiast would find hard to pass up. And it's worth every bite. Moreover, while it looks ultra fancy, it doesn't demand a chef's skill set.
Ingredients you need
Navigating through the aisles of your grocery store, here are the essentials you need to grab to make this Pommes Duchesse recipe. The key with Pommes Duchesse is to source quality because when the ingredient list is simple, every component matters.
- Yellow potatoes: Opt for starchy varieties like Yukon golds for the best results. Yukon gold potatoes are nice and starchy, giving them great texture, and they absorb less water than russet potatoes, so they're less likely to become mushy.
- Egg yolks: These give the dish its signature rich consistency. This recipe was tested using large egg yolks.
- Heavy cream: This contributes to the creamy texture. You could substitute half-and-half or full-fat milk, but heavy cream will yield the best result.
- Butter: Vital for flavor. I use unsalted butter, but if you only have salted, reduce the amount of salt you're adding to the potatoes.
- Salt and pepper: These essential seasonings can be adjusted based on personal preference.
- Optional additions: Feel free to add a bit of freshly grated nutmeg or a bit of minced fresh rosemary or thyme if you like. Some shredded gruyere or parmesan cheese would add even more richness and flavor.
- Optional garnishes: Fresh herbs like minced chives or parsley add a pretty bit of green to the finished dish, but they're optional. You could also add a drizzle of sour cream on top of the potatoes.
Equipment you need
You don't need a lot of fancy equipment to make these, but you do need a few items:
- A potato ricer, potato masher, or a food mill
- A pastry bag or large piping bag with a large star tip.
- A pastry brush

How to make it
Pommes Duchesse looks impressive, but the process to make it is surprisingly straightforward and takes just about 40 minutes to make from start to finish. Here are the basic steps:
- Bring a large pot of salted water to a boil, and then put the potatoes in the pot and bring to a simmer again. Cook until the potatoes are soft enough to pierce effortlessly with a fork.
- While the potatoes are cooking, preheat the oven and prepare a baking sheet by spraying with nonstick cooking spray or lining with parchment paper. I prefer using a lined baking sheet for easier cleanup.
- Drain the potatoes and then add the cream, salt, pepper, and some of the butter. Mash the potatoes, mixing in the other ingredients in the process, aiming for a mostly smooth consistency.
- Once the potatoes are mashed and the mixture is well combined, add the yolks and stir to incorporate them.
- Transfer the mixture to a piping bag fitted with a large star tip. Use the pastry bag to pipe the potatoes onto the parchment-lined baking sheets in a circular motion into rosette swirls.
- Using a pastry brush, brush the piped potatoes with melted butter and bake until golden brown.
What to serve alongside duchess potatoes
These golden beauties are perfectly majestic when paired with the right partners. When thinking of proteins, they effortlessly complement roast meats, especially the robust flavors of beef or lamb. They'd also go great alongside a Thanksgiving turkey, Instant Pot Ham, Air Fryer Whole Chicken, or Duck Confit for an elegant dinner party.
For veggies, add Pan Seared Brussels Sprouts or Dry Fried Green Beans. Or try a crisp Kale Salad or Green Bean Salad.
