Duchess Potatoes
Equipment
- 1 potato masher
- parchment paper
- 1 piping bag
- 1 large baking sheet
Ingredients
- 2 large russet potatoes, peeled and chopped into cubes
- 1/2 teaspoon salt
- 1/2 teaspoon white pepper
- 3 tablespoons butter
- 1/3 cup grated baby Swiss cheese
- 1/8 cup heavy cream
- 3 egg yolks
- 3 tablespoons grated Parmesan cheese
Instructions
- Preheat oven to 400 degrees Fahrenheit.
- Place potato cubes in a pan of salted boiling water. Cook over medium-high heat until tender. Drain.
- Mash potatoes with a potato masher until they are smooth with only a few small lumps, but not so much that the potatoes become "gluey".
- Add salt and pepper, butter and baby Swiss cheese. Stir until butter and cheese are melted.
- Add heavy cream and stir to combine.
- Add egg yolks, one at a time and stir briskly into the potatoes.
- Line a large baking sheet with parchment paper. (dab a little water underneath each corner of parchment paper to help it adhere to the baking sheet)
- Place some of the potato mixture into a piping bag filled with a 1/2"star tip. Fold top of bag over so the potato mixture will not come out of the bag (do not overfill the bag).
- Pipe 20 (each the size of a 50 cent piece) round potato mounds onto lined baking sheet, about 2 inches apart.
- Sprinkle each mound with Parmesan cheese.
- Bake potatoes for 10 minutes, rotate pan in oven, then bake 10 more minutes.
- Remove pan from oven, turn on broiler. Return pan to oven and broil 3 – 4 minutes until tops of potatoes are golden brown.
