Duchess potatoes look fancy, but they’re secretly so simple. I made these as a side dish once for a dinner party and everyone assumed I’d spent hours prepping, but the truth is, they are super easy to make!
Crispy on the outside, fluffy inside, and totally make ahead friendly. They’re perfect for holiday meals or anytime you want a side that feels a little extra without actually being extra. Call them “pommes duchesse” if you want to be fancy.

Key Recipe Ingredients
The full list of ingredients and amounts is found in the printable recipe card below.
- Potatoes. Russet potatoes or Yukon Gold potatoes work best for smooth mashed potatoes. Avoid waxy potatoes like red potatoes.
- Butter. Use salted butter for flavor. If you use unsalted butter, you’ll want to add a little more salt to your potatoes. Start with 2 tablespoons of butter and add more if you want.
- Milk. Totally optional. It makes the mixture smoother, but you can skip it or use heavy cream or half and half for a richer version.
- Kosher salt and black pepper. Season to your liking. Taste the mixture before piping.

This next part is only a photo tutorial of the recipe steps. The full list of ingredients, quantities and instructions can be found in the printable recipe card below.
STEP 1: Get prepped. Peel and chop the potatoes. Line 2 baking sheets with parchment paper or silicone mats. Preheat oven to 400°F.
STEP 2: Boil the potatoes. Add water, salt and potatoes to in a large pot and cover. Bring to a boil, then cook until the potatoes are fork tender, about 15 minutes.
STEP 3: Mash the potatoes. Drain the potatoes and return to the pot. Use a potato masher, and mash with butter and milk until mostly smooth. Then use a hand mixer to beat until creamy and fluffy with no big chunks. You can also use a potato ricer or food mill to get all the lumps out well. Add more butter or milk if needed.
STEP 4: Pipe the potatoes: Season with salt and pepper. Scoop potato mixture into a pastry bag fitted with a large star tip. Pipe the potatoes onto your lined trays, in 2 to 3 inch swirl shapes, leaving a space between each.
STEP 5: Bake. Bake for 18 to 22 minutes until golden brown and crisp on the edges.
Troubleshooting Guide – Common Problems and Solutions
- Potatoes get stuck in piping bag: Use an electric mixer or run the potatoes through a potato ricer for a super smooth and whipped consistency. Make sure the potatoes are completely tender before mashing. Undercooked chunks will ruin the texture.
- Potatoes are too runny to pipe. Use an electric mixer for a super smooth and whipped consistency. Don’t overdo the milk. Too much liquid will make them hard to pipe and they won’t hold their shape.
- Potatoes didn’t brown. Use the broiler to briefly brown the tops. You can also help it by brushing the tops of the potatoes with melted butter or an egg wash.
- Potatoes stuck to pan. Pipe directly onto parchment or a silicone mat for easy removal after baking.
Kylee’s Notes
- If you don’t have a piping bag, use a heavy duty zip lock bag, and cut the corner off to use as the nozzle for piping.
Add these to the top of a chicken or beef casserole, and make it look fancy! - If you want to add bacon bits, sprinkle them on after baking to avoid clogging the piping tip.
- Add one or two egg yolks to your potatoes to make them super puffy and fluffy.
- Add a pinch of nutmeg to the potatoes with the salt and pepper.
How to store leftovers
Refrigerator
Store in an airtight container in the fridge for up to 3 days.

To freeze, place the piped (but unbaked) duchess potatoes on a tray and freeze until solid, then transfer to a freezer bag and store for up to 2 months.
Reheating
Reheat baked duchess potatoes in a 350°F oven for 10 to 15 minutes until warmed through. If reheating from frozen, bake directly from frozen at 375°F for 20 to 25 minutes.

Duchess Potatoes
Recommended Equipment
- Potato masher (or electric mixer)
- Piping Bag (with large star tip)
- Baking sheets
- Parchment Paper (or silicone mats)
Ingredients
- 2.5 pounds potatoes (washed and scrubbed)
- 2 to 3 tablespoons butter
- 1/4 cup milk (optional)
- salt and pepper (to taste)
Directions
- Get prepped: Peel and roughly chop 2.5 pounds potatoes. Line two baking sheets with parchment paper or silicone baking mats. Preheat the oven to 400°F.
- Boil the potatoes: Bring a large pot of water to a boil. Add the potatoes and cook until fork-tender, about 15 minutes.
- Mash the potatoes: Drain the water and return the potatoes to the pot off the heat. Mash them until mostly smooth, then add 2 to 3 tablespoons butter and 1/4 cup milk (if using). Keep mashing until creamy. Use a hand mixer if you want extra smooth, fluffy potatoes. You’re aiming for a whipped texture that’s soft but not wet.
- If the mixture feels too stiff, add more butter or milk. The texture should be soft and whipped but not wet or gloopy. Make sure no large chunks remain.
- Form the duchess potatoes: Stir in salt and pepper to taste. Scoop the potato mixture into a piping bag fitted with a large star tip.
- Pipe 2 to 3 inch swirls onto the baking sheets, starting in the center and spiraling outward, then back to the middle to form a cone shape. Leave about 1 inch between each.
- Bake: Pop them in the oven and bake for 18 to 22 minutes, until the tops are golden and the edges are crisp.
