Ingredients
Method
- Put the potatoes in a 6-quart pot and cover with cold water by about 1 inch.
- Stir 1 tablespoon kosher salt into the water.
- Bring the water to a boil over high heat.
- Reduce the heat and simmer for 15 to 20 minutes, until a fork slides easily into the potato pieces.
- While the potatoes cook, warm the butter and heavy cream in a 1-quart saucepan over low heat for 3 to 5 minutes, until the butter melts and the cream is steaming; do not let it boil.
- Drain the potatoes well and return them to the pot.
- Set the pot over low heat for 1 to 2 minutes, shaking it gently, to let excess moisture evaporate.
- Remove the pot from the heat and mash the potatoes until mostly smooth.
- Gently stir in the warm cream mixture, remaining 1 1/2 teaspoons kosher salt, and black pepper until creamy.
- Serve warm.
Notes
For the smoothest texture, avoid overmixing the potatoes. Refrigerate leftovers in an airtight container for 3 to 4 days; freezing is possible, though the texture may change slightly when reheated. For a dairy-free option, use plant-based butter and an unsweetened dairy-free cream alternative.
