This duchess potato recipe creates the classic French piped potatoes that are as fancy as royalty. They're elegant and irresistibly tasty. Bon appetit!
Peel the potatoes and cut them into four pieces. Place them into a pot of boiling water and cook them until they are fork-tender.
Drain the water from the potatoes. Mash the potatoes until they are perfectly smooth. Add butter, salt, and heavy whipping cream to the mashed potatoes. Mash again to combine. Whisk the egg yolks, then add them slowly into the potatoes, stirring constantly until combined.
Place the mashed potatoes into a piping bag. Make sure there aren't any large pieces or lumps otherwise they will get stuck as you are piping. Pipe the potatoes onto a lined baking sheet, about 2-3 inches in size. Leave about an inch of space between each potato mound.
Melt 2 tablespoons of butter and gently brush the tops of the potatoes with it.
Bake the potatoes at 425°F for 15-20 minutes or until the tops are golden brown. Enjoy!
