Ingredients Equipment Method Notes

Ingredients
  

  • 1 head garlic large
  • 1 tsp olive oil
  • 3 lb Yukon Gold potatoes peeled and cut into 1.5-inch chunks
  • 3 qt water
  • 2 tsp kosher salt divided
  • 6 tbsp unsalted butter cut into pieces
  • 0.75 cup whole milk
  • 0.25 tsp black pepper freshly ground

Equipment

  • 1 small baking sheet
  • 1 6-quart pot
  • 1 small saucepan

Method
 

  1. Preheat the oven to 400°F.
  2. Slice the top off the large garlic head to expose the cloves.
  3. Drizzle the garlic with olive oil and wrap it in foil.
  4. Roast the garlic on a small baking sheet for 40 to 50 minutes, until the cloves are very soft and lightly golden.
  5. Put the potatoes in a 6-quart pot with the water and 1 1/2 teaspoons of the salt.
  6. Bring to a boil over high heat, then reduce the heat and simmer for 15 to 20 minutes, until a knife slides easily into the chunks.
  7. While the potatoes cook, warm the milk in a small saucepan over low heat for 3 to 4 minutes, until steaming but not boiling.
  8. Drain the potatoes well and return them to the pot.
  9. Let the garlic cool until easy to handle, then squeeze the cloves from their skins into the potatoes.
  10. Add the butter and mash until mostly smooth.
  11. Gradually stir in the warm milk, remaining 1/2 teaspoon salt, and black pepper until the potatoes are creamy.
  12. Serve hot.

Notes

For the creamiest texture, mash the potatoes while hot and add the warm milk gradually. Refrigerate leftovers for up to 4 days; freezing is not recommended because the texture may become grainy. For a dairy-free version, use plant-based butter and unsweetened, unflavored oat milk.
