2 tbsp Double / Heavy Cream (at room temp)
60g / 3/4 cup freshly grated Parmesan (plus more to serve)
4 large Egg Yolks
finely diced Fresh Parsley (to serve)
Olive Oil (as needed)
Salt & Pepper (as needed)

How to Make Garlic Parmesan Duchess Potatoes

Step 1: Roast the Garlic

Slice the tip off the garlic bulb to expose the cloves and drizzle with olive oil.
Wrap in foil and place in an oven preheated to 180C/356F for 50-60 minutes until soft and caramelized.
Allow it to cool briefly, then squeeze out the garlic into a bowl. Mash with a fork, adding a pinch of salt.

Step 2: Prepare the Potatoes

Peel and dice the baking potatoes into large bite-sized pieces.
Place them in a large pot of cold water with 2 teaspoons of salt.
Bring to a boil and cook until fork-tender, about 15-20 minutes. Drain and let steam dry in a colander for about 5 minutes.

Step 3: Mash Everything Together

Return the potatoes to the pot and add 3 tablespoons of butter along with heavy cream.
Stir in the roasted garlic and Parmesan cheese while mashing until smooth.
Season generously with salt and pepper. Let cool slightly before stirring in egg yolks one at a time until fully incorporated.

Step 4: Pipe the Potatoes

Spoon the potato mixture into a piping bag fitted with a large star tip.
Pipe swirly dome shapes onto a baking tray lined with baking paper, aiming for approximately 10 servings.

Step 5: Bake Until Golden Brown

Drizzle melted butter over each piped potato shape so it coats evenly.
Bake in an oven preheated to 200C/400F for about 15-20 minutes or until golden brown on top.

Step 6: Serve and Enjoy!

Not roasting the garlic properly: Roasting garlic enhances its flavor. Wrap it tightly in foil and ensure it becomes soft and caramelized for the best taste.

Skipping seasoning: Don’t forget to season your potatoes well with salt and pepper. Taste the mixture before adding egg yolks to ensure balanced flavors.
Using cold ingredients: Room temperature butter and cream mix better with hot potatoes, creating a smoother texture. Always let them sit out for a bit before use.
