Equipment

  • Large pot
  • Potato masher or ricer (recommended for smoothness)
  • Baking sheet
  • Parchment paper
  • Piping bag with a large star tip
  • Mixing bowls
  • Spatula

Method
 

Step 1: Cook the Potatoes
  1. Peel potatoes and cut into chunks.
  2. Boil in salted water for 15–18 minutes, until fork-tender.
  3. Drain completely and return to the pot for 1 minute to evaporate excess moisture.
Step 2: Mash Until Silky
  1. Pass potatoes through a ricer or mash until completely smooth — lumps will ruin the piping.
  2. Add:
  3. softened butter
  4. warm heavy cream
  5. salt
  6. pepper
  7. nutmeg (optional)
  8. Mix until creamy.
Step 3: Add Egg Yolks
  1. Let mixture cool 2–3 minutes, then mix in egg yolks until fully incorporated.
  2. The mixture should be thick, silky, and pipe-able — add a spoon of cream if too thick.
Step 4: Pipe the Potatoes
  1. Preheat oven to 425°F (220°C).
  2. Line a baking tray with parchment.
  3. Transfer potato mixture to a piping bag fitted with a large star tip.
  4. Pipe tall swirls or rosettes onto the baking sheet, spacing slightly apart.
  5. Brush lightly with melted butter or egg wash for extra golden color.
Step 5: Bake
  1. Bake 15–20 minutes until:
  2. edges are golden
  3. tops lightly crisp
  4. centers still soft and pillowy
  5. Serve warm.

❓ 10 FAQs

Why did my rosettes collapse?
Potatoes were too wet — dry them well and avoid too much cream.
Can I use a regular masher?
Yes, but a ricer makes the smoothest results.
Do egg yolks make a big difference?
Yes — they give structure, richness, and golden color.
Can I use milk instead of cream?
Yes, but the potatoes won’t be as rich.
Can I pipe them ahead of time?
Absolutely — refrigerate on the tray for up to 24 hours.
Can I freeze them?
Freeze unbaked for best results.
Why are my potatoes gummy?
Overmixing — be gentle after adding egg yolks.
Do I have to pipe them?
No — spoon mounds work, but piping makes them beautiful.
What potatoes are best?
Yukon Gold = creamy
Russet = fluffiest
Can I make them vegan?
Yes — use plant cream + vegan butter + potato starch instead of eggs.
