Boil the Potatoes:
Place the cubed potatoes and peeled garlic cloves in a large pot.
Add enough cold water to the pot to cover the potatoes by about an inch.
Place the pot on the stove over high heat and bring it to a boil.
Reduce the heat to medium-high and simmer for 10-15 minutes or until the potatoes are fork-tender.
Drain and Mash:
Drain the potatoes and garlic in a colander and return them to the pot.
Heat the Cream and Butter:
In a small saucepan, heat the heavy cream and butter over low heat until the butter has melted. Do not let it boil.
Mash and Mix:
Using a potato masher or a potato ricer, mash the potatoes and garlic in the pot.
Pour the warm cream and butter mixture over the mashed potatoes.
Add the black truffle oil, grated Parmesan cheese, salt, and pepper to taste.
Stir everything together until the potatoes are creamy and well combined with the other ingredients.
Adjust Seasoning:
Taste the mashed potatoes and adjust the salt, pepper, and truffle oil according to your preference. You can add more truffle oil for a stronger truffle flavor.
Serve:
Transfer the mashed potatoes to a serving dish.
Garnish with fresh chives or parsley if desired.
Serve hot and enjoy your luxurious Black Truffle and Parmesan Mashed Potatoes!
