Ingredients
For the Potatoes
- 1 large bulb of garlic
- 1.3kg / 2.8lb baking potatoes
- 5 tbsp / 75g butter (2 tbsp/30g melted, the rest left at room temp)
- 2 tbsp double / heavy cream (at room temp)

For Garnish
- 2 tablespoons fresh parsley, finely chopped

How to Make Garlic Parmesan Duchess Potatoes
Step 1: Roast the Garlic
Slice the tip off the garlic bulb, exposing the cloves. Drizzle with olive oil and wrap in foil. Place in the oven at 180C/356F for 50-60 minutes until very soft and golden. Allow to cool slightly before squeezing out the cloves into a bowl. Add a pinch of salt and mash until smooth.
Step 2: Prepare the Potatoes
Peel and dice the baking potatoes into large pieces. Add them to a pot of cold water with 2 teaspoons of salt. Bring to a boil and cook until fork-tender. Drain in a colander and let steam dry for about 5 minutes.
Step 3: Combine Ingredients
Return the drained potatoes to the pot. Mash them with 3 tbsp of melted butter and heavy cream until smooth. Stir in roasted garlic and Parmesan cheese, seasoning generously with salt and pepper. If still hot, allow to cool briefly before adding egg yolks one by one until well blended.
Step 4: Pipe the Mixture
Transfer the potato mixture into a piping bag fitted with a large star tip. Pipe swirly dome shapes onto a baking tray lined with parchment paper, aiming for about 10 pieces.
Step 5: Bake Until Golden
Drizzle melted butter over each piped mound so that it coats them as it melts. Bake in an oven preheated to 200C/400F for about 15-20 minutes until golden brown. Keep an eye on them to avoid burning; turn the tray if necessary.
Step 6: Serve and Enjoy
Garnish your Garlic Parmesan Duchess Potatoes with chopped parsley and extra Parmesan before serving hot. Enjoy this delightful side dish that’s sure to impress!
