Here is the recipe I use for twice-baked potatoes. This makes for a nice option to mashed potatoes. My family eats them up. Easy to make if you have the time.
Ready
6 russet potatoes (about 3 lbs.)
6 large egg yolks
4 tablespoons unsalted butter, softened
½ cup heavy cream
1 ½ cups grated Gruyere cheese
1 tablespoon + 2 teaspoons coarse salt
freshly ground pepper
Set
Aluminum foil
Baking sheet
Bowl
Potato masher
Large spoon
Go!
Preheat oven to 425°F.
Wrap potatoes in aluminum foil, and bake until softened, about 1 hour.
Remove from oven and let cool.
After potatoes cooled cut each in half longways.
Scoop out the inside flesh into a bowl and set aside the skins (you will use the skins later).
Mash flesh in bowl.
Stir in egg yolks, butter, cream, 1 cup Gruyere, salt and pepper.
Scoop filling back into the skins.
Cover with foil and refrigerate until 30 minutes prior to serving.
Re-heat oven to 400°F
Place filled potatoes on a baking sheet, and sprinkle with remaining Gruyere.
Bake until filling is set and tops are golden brown, about 25 minutes.
