Make an elegant side dish that impresses guests. This recipe shows you how to create creamy mashed potato swirls that bake to a beautiful golden brown with crispy edges. It is a simple technique for a showstopper side dish.

Ingredients

Scale
  • 2 pounds Russet potatoes, peeled and quartered
  • 1/2 cup unsalted butter, softened
  • 1/2 cup heavy cream, warmed
  • 4 large egg yolks
  • 1/2 teaspoon salt
  • 1/4 teaspoon black pepper
  • Pinch of nutmeg
  • 1 large egg, beaten (for egg wash)

Instructions

  1. Place the peeled and quartered potatoes in a large pot and cover them with cold, salted water.
  2. Bring the water to a boil and cook the potatoes until they are very tender, about 15 to 20 minutes.
  3. Drain the potatoes well and return them to the hot, empty pot over low heat for one minute to dry out any excess moisture. Shake the pot gently.
  4. Mash the potatoes until completely smooth. You can use a potato ricer for the best texture.
  5. Add the softened butter and mix until fully incorporated.
  6. Gradually mix in the warm heavy cream until the mixture is smooth and creamy.
  7. Remove the pot from the heat. Whisk the four egg yolks lightly in a small bowl, then stir them into the potato mixture along with the salt, pepper, and nutmeg. Mix until just combined; do not overmix.
  8. Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Line a baking sheet with parchment paper.
  9. Transfer the potato mixture to a large piping bag fitted with a large star tip (like a Wilton 1M). This step is key for the classic look.
  10. Pipe the potatoes onto the prepared baking sheet in decorative swirls or mounds, about 2 inches wide.
  11. Brush the tops of the piped potatoes lightly with the beaten egg wash.
  12. Bake for 20 to 25 minutes, or until the edges are golden brown and slightly crisp.
  13. Serve immediately as an elegant potato side dish.

Notes

  • For a richer flavor, substitute 1/4 cup of the heavy cream with 1/4 cup of cream cheese when mixing.
  • If you do not have a piping bag, you can drop spoonfuls of the mixture onto the baking sheet for a rustic look.
  • You can prepare the potato mixture up to 24 hours ahead. Store it covered in the refrigerator and bring it close to room temperature before piping.
