Ingredients
Scale
2 pounds Russet potatoes, peeled and quartered
1/2 cup unsalted butter, softened
1/2 cup heavy cream, warmed
2 large egg yolks
1/2 teaspoon salt
1/4 teaspoon black pepper
Pinch of nutmeg
1/4 cup grated Parmesan cheese (optional, for flavor variation)
1 large egg, beaten (for egg wash)
Instructions
Place the peeled and quartered potatoes in a large pot and cover with cold, salted water. Bring to a boil and cook until the potatoes are very tender, about 15 to 20 minutes.
Drain the potatoes completely. Return them to the hot, empty pot over low heat for one minute, stirring constantly to dry them out slightly. This step helps prevent watery potatoes.
Mash the potatoes thoroughly until completely smooth. You can use a potato ricer or a hand masher for the best texture.
In a separate bowl, mix the softened butter, warm heavy cream, egg yolks, salt, pepper, and nutmeg. If using, mix in the Parmesan cheese now.
Add the butter mixture to the mashed potatoes. Mix until just combined and smooth. Do not overmix, as this can make the potatoes gluey. The mixture should be thick enough to hold its shape.
Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Transfer the potato mixture to a large piping bag fitted with a large star tip (like a Wilton 1M). If you do not have a piping bag, you can use a large zip-top bag with a corner snipped off, or simply drop spoonfuls onto the baking sheet for a rustic look.
Pipe mounds or swirls onto the prepared baking sheet, leaving about 1 inch between each one.
Brush the tops of the potato swirls lightly with the beaten egg wash. This promotes browning and crispness.
Bake for 20 to 25 minutes, or until the edges are golden brown and crisp. Serve immediately for the best texture.
Notes
For the creamiest texture, use a potato ricer instead of a standard masher.
You can prepare the piped potatoes up to 24 hours ahead. Place the piped mounds on the baking sheet, cover loosely with plastic wrap, and refrigerate. Before baking, let them sit at room temperature for about 30 minutes, then apply the egg wash and bake as directed.
If you skip the piping bag, use two spoons to drop rustic mounds onto the sheet. They will still bake up crispy on the edges.
