Method
- Heat the oven to 350°F.
- Grease a 9x13-inch baking dish.
- Put the potatoes in a 12-quart pot and cover with the cold water.
- Stir in the kosher salt.
- Bring to a boil over high heat.
- Reduce the heat to maintain a steady simmer and cook for 15 to 20 minutes, until the potatoes are very tender when pierced with a fork.
- Drain the potatoes well in a colander.
- Return the potatoes to the pot.
- Mash with 1 1/2 sticks (12 tablespoons) of the butter and the cream cheese.
- Mash in the half-and-half, heavy cream, seasoned salt, and black pepper until creamy, taking care not to overmix.
- Spread the potatoes in the prepared baking dish.
- Dot with the remaining 2 tablespoons butter.
- Bake for 20 to 30 minutes, until hot throughout and lightly browned around the edges.
Notes
For the creamiest texture, avoid overmixing the potatoes. Refrigerate leftovers for 3 to 4 days; they can be frozen, though the texture may soften after thawing. For a dairy-free swap, use plant-based butter, cream cheese, and cream alternatives.
