Ingredients
2 ½lb.russet or Yukon gold potatoes
4tablespoonsbutter
⅓cupwhipping cream
1 ½teaspoonssea salt
1teaspoonpepper
4largeegg yolks
1whole egg + 1 tablespoon milk, for the egg wash
Instructions
Preheat your oven to 375 degrees. Line 2 baking sheets with parchment paper.
Peel the potatoes and cut into quarters. Place them in a large pot and cover them with water. Bring the water to a boil and cook until the potatoes are soft, about 10-15 minutes. Drain the potatoes.
2 ½ lb. russet or Yukon gold potatoes
Pass the potatoes through a potato ricer. Alternatively, you can mash them with a potato masher, making them as smooth as possible.
Add the butter and let it melt. Mix in the cream, salt, and pepper. Taste and add more salt, if wanted. When the mashed potatoes have cooled slightly, stir in the egg yolks.
4 tablespoons butter, ⅓ cup whipping cream, 1 ½ teaspoons sea salt, 1 teaspoon pepper, 4 large egg yolks
Transfer the mashed potatoes to a pastry bag fitted with a large star tip. (You'll need to work in batches.) Pipe the potatoes onto the parchment-lined baking sheets into swirls about 3 inches in diameter.
Whisk the whole egg with the milk then gently brush it over the duchess potatoes. You don't want to use a lot and you'll likely have leftovers.
1 whole egg + 1 tablespoon milk
Bake the potatoes for 20-25 minutes, or until they have started to turn golden along the ridges. Serve with a little minced parsley, chives, or thyme sprinkled over the top.
Notes
Make duchess potatoes 24 hours in advance
Complete steps 2-5 then place the trays of duchess potatoes into your fridge for 1 hour. After an hour the potatoes will be firm enough that you'll be able to cover them with wrap. Add a few extra minutes to the cooking time.
Freeze duchess potatoes
Complete steps 2-5 then place the trays of duchess potatoes into your freezer. Once they are solid you can place them into a freezer bag. They will keep well for at least 3 months. Bake them from frozen adding about 10 minutes to the baking time.
