Ingredients

Gather these ingredients to make your Duchess Potatoes:

2 lbs (900g) russet potatoes, peeled and cut into chunks
4 tablespoons unsalted butter, divided
1/2 cup whole milk (or heavy cream for extra richness)
1/2 cup grated Parmesan cheese (optional)
1/4 teaspoon garlic powder
1/4 teaspoon onion powder (optional)
Salt and pepper, to taste
1 large egg, beaten (for egg wash)
Fresh herbs, such as parsley or chives (optional, for garnish)

Ingredient Highlights

Russet Potatoes: Russet potatoes are ideal for this dish because they are starchy, which results in a fluffy and smooth mashed potato.
Butter: Butter adds richness and creaminess to the potatoes, giving them that melt-in-your-mouth texture.
Parmesan Cheese: Adding Parmesan cheese enhances the flavor and gives the potatoes a subtle umami boost.
Egg: The egg helps bind the mashed potatoes together and gives the rosettes a golden, crisp finish when baked.

Step-by-Step Instructions

Here’s how to make this recipe:

Prepare the Potatoes:

Boil the Potatoes: Place the peeled and cut potatoes into a large pot and cover them with water. Add a pinch of salt and bring the water to a boil. Cook the potatoes for 15-20 minutes, or until they are fork-tender.
Drain and Mash: Drain the potatoes and return them to the pot. Use a potato masher or a potato ricer to mash the potatoes until smooth. Ensure there are no lumps.

Make the Mashed Potato Mixture:

Add Butter and Milk: Add the butter, and then pour in the milk (or heavy cream). Stir until the mixture is smooth and creamy.
Season: Season with salt, pepper, garlic powder, and onion powder (if using). Add the grated Parmesan cheese, if desired, and mix well. Taste and adjust the seasoning as needed.
Incorporate the Egg: Allow the mashed potatoes to cool slightly before adding the beaten egg. Stir the egg into the potatoes, ensuring the mixture is smooth and well-combined.

Pipe and Bake:

Preheat the Oven: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper or a silicone baking mat.
Pipe the Potatoes: Transfer the mashed potato mixture into a piping bag fitted with a large star tip. Pipe the potatoes into rosettes on the prepared baking sheet, leaving a little space between each one.
Brush with Egg Wash: Brush the tops of the piped potatoes with the beaten egg to give them a golden, shiny finish when baked.
Bake: Bake in the preheated oven for 20-25 minutes, or until the edges are golden and crispy, and the potatoes are heated through.
Serve: Remove the Duchess Potatoes from the oven and transfer them to a serving platter. Garnish with fresh herbs if desired and serve immediately.
