Ingredients
Method
- Put the potatoes in a 6-quart pot with the water and kosher salt.
- Bring the potatoes, water, and kosher salt to a boil over high heat.
- Reduce the heat to maintain a steady simmer and cook the potatoes for 15 to 20 minutes, until easily pierced with a fork.
- While the potatoes cook, microwave the milk in a microwave-safe measuring cup for 30 to 45 seconds, until warm.
- Drain the potatoes well and return them to the pot.
- Let the potatoes steam-dry for 1 minute.
- Add the butter, Boursin, warm milk, and black pepper, then mash until creamy.
Notes
For the smoothest mash, warm the milk and let the drained potatoes steam-dry before mashing. Refrigerate leftovers for 3 to 4 days; freezing is possible, though the texture may change. For a dairy-free variation, use dairy-free milk, plant-based butter, and a dairy-free garlic-herb cheese.
