Ingredients
  

For the roasted garlic
  • 1 garlic large head
  • 1 tbsp olive oil
For the potatoes
  • 3 lb Yukon Gold potatoes peeled and cut into 1 1/2-inch chunks
  • 3 qt cold water
  • 1 tbsp kosher salt divided
  • 1 tsp kosher salt remaining, divided
  • 8 tbsp unsalted butter
  • 0.5 cup heavy cream
  • 0.25 tsp black pepper

Method
 

Roast the garlic
  1. Heat the oven to 400°F.
  2. Slice about 1/4 inch off the top of the garlic head to expose the cloves.
  3. Drizzle the garlic with olive oil and wrap it in foil.
  4. Roast the garlic for 40 to 50 minutes, until the cloves are very soft and lightly golden.
  5. Let it cool until easy to handle.
  6. Squeeze the cloves from their skins into a small bowl.
Cook the potatoes
  1. Put the potatoes, cold water, and 1 tablespoon of the kosher salt in a 6-quart pot.
  2. Bring to a boil over high heat, then reduce the heat and simmer for 15 to 20 minutes, until the potatoes are fork-tender.
  3. While the potatoes cook, warm the butter and heavy cream in a small saucepan over low heat until the butter melts; do not let the mixture boil.
Mash the potatoes
  1. Drain the potatoes and return them to the pot.
  2. Mash until mostly smooth.
  3. Mix in the roasted garlic and warm butter-cream mixture.
  4. Stir in the remaining 1 teaspoon kosher salt and the black pepper, then serve.

Notes

For the smoothest texture, mash the potatoes while hot and mix in the warmed butter and cream. Refrigerate leftovers in an airtight container for 3–4 days; freezing is not recommended because the texture may change. For a dairy-free version, use plant-based butter and unsweetened non-dairy cream.
