Pommes de Terre Duchesse are a classic French side dish that traditionally use regular potatoes. However, our Sweet Potato Duchesse Potatoes bring a modern twist by incorporating the natural sweetness and vibrant colour of sweet potatoes. This dish is perfect for when you want to impress your guests with something that looks and tastes sophisticated, yet is surprisingly simple to prepare. The combination of sweet potatoes and butter creates a creamy texture, while a hint of nutmeg adds an aromatic touch.

Instructions

Boil the sweet potatoes

Place the cubed sweet potatoes in a large pot of salted water. Bring to a boil, then reduce heat and simmer until tender, about 15 minutes.

Pro tip: Ensure the potatoes are evenly cubed for uniform cooking.

Mash the sweet potatoes

Drain the sweet potatoes and return them to the pot. Mash until smooth and lump-free.

Pro tip: Use a potato ricer for the smoothest texture.

Prepare the duchesse mixture

Mix the mashed sweet potatoes with butter, heavy cream, egg yolks, nutmeg, salt, and pepper until fully combined.

Pro tip: Mix while the potatoes are still warm to help the butter melt smoothly.

Preheat the oven

Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.

Pipe the duchesse potatoes

Transfer the sweet potato mixture to a piping bag fitted with a large star tip. Pipe small mounds onto the prepared baking sheet.

Pro tip: Pipe in a circular motion to create a classic duchesse shape.

Apply the egg wash

In a small bowl, mix the beaten egg with milk. Brush each mound lightly with the egg wash.

Pro tip: This will give the duchesse potatoes a golden, shiny finish.

Bake

Bake in the preheated oven for 10-12 minutes or until the tops are golden brown.

Pro tip: Keep an eye on them to avoid over-browning.
