Duchess Potato Casserole Recipes

DUCHESS POTATOES

Steps:

• In a large pot, cover potatoes with cold salted water by 2 inches. Bring to a boil; reduce to a rapid simmer and cook until tender, 15 minutes. Drain in a colander, let sit 5 minutes, then return to pot. Add butter and, with a potato masher, mash until smooth. Season with salt and pepper. Add 2 egg yolks, 1/4 cup cream, and pinch of nutmeg; stir until combined.
• Preheat oven to 450 degrees. Line a baking sheet with parchment and lightly butter paper. Dollop mixture in 8 equal portions on sheet, 2 inches apart. Using the back of a spoon, create a small well in the center of each. Freeze until firm, 15 minutes. Whisk together remaining egg yolk and 2 teaspoons cream. Brush on potatoes and bake until golden, 15 minutes.

DUCHESS POTATOES

Steps:

• Prepare a piping bag with large open star tip.
• Preheat oven to 400 degrees F (200 degrees C). Grease a baking sheet.
• Fill a 3-quart pot with 4 inches water and 1 teaspoon salt. Add potatoes; bring to a boil. Reduce heat to low; simmer until tender, 20 to 25 minutes. Drain; return potatoes to the pot.
• Cook potatoes over low heat until remaining water steams off, about 3 minutes. Let cool, at least 15 minutes.
• Place potatoes in a food processor and process until smooth. Let stand for 5 minutes. Add butter, egg yolks, remaining 1 teaspoon salt, nutmeg, and pepper. Mix until just combined; spoon into the piping bag.
• Pipe potato mixture onto the prepared baking sheet into eighteen 2-inch rosettes with a circular motion, finishing with a small peak in the center. Refrigerate until slightly firmer, about 25 minutes.
• Mix egg and heavy cream together in a bowl; brush mixture onto the rosettes.
• Bake in the preheated oven until golden brown, 35 to 40 minutes.

DUCHESS POTATOES

Steps:

• Preheat the oven to 375 degrees F. Line a baking sheet with parchment or a silicon baking mat.
• Lay the boiled potatoes on a baking sheet and place into the oven until slightly dried on the surface, 10 to 15 minutes.
• Remove the potatoes from the oven and process through a ricer or food mill. Allow to cool in a bowl for about 5 minutes.
• Add the egg yolks, butter, a couple generous pinches of salt, a generous pinch of pepper, a pinch of nutmeg and 3/4 cup cream. Stir with a rubber spatula to combine. Taste and make sure the potatoes have been adequately salted.
• Transfer to a large pastry bag and pipe through a large star tip in a circular/upward spiral motion onto the prepared baking sheet.
• Make an egg wash by mixing the whole egg with the remaining 1/2 cup cream. Lightly brush the piped potatoes with the egg wash. (This is a little easier if you chill the piped potatoes for half an hour or so.)
• Bake until golden brown around the edges. Serve on a pretty platter!

DUCHESS BAKED POTATOES

Steps:

• Place potatoes in a large pot and pour in water to cover by 2"; season with salt. Bring to a boil over medium-high. Reduce heat and simmer until a paring knife very easily slides through potatoes, 25-35 minutes. Drain and let cool slightly.
• Preheat oven to 425°F. Whisk egg yolks, garlic, cream, sour cream, butter, and peppercorns in a large bowl; season generously with salt. Peel potatoes and pass flesh through a ricer or a food mill (or mash them by hand if you don't mind a few lumps) directly into bowl with egg mixture. Fold in gently (be careful not to overmix). Transfer to a 3-quart baking dish and decoratively shingle or swirl surface. Bake, rotating once, until golden brown and slightly puffed, 30-40 minutes.
• Do Ahead
• Dish can be assembled 1 day ahead. Cover and chill. Increase bake time by 5-10 minutes.
