  • 5 lbs russet potatoes, peeled and cut into 1 inch cubes
  • 4 garlic cloves, peeled and smashed
  • 1 cup whole milk, at room temperature
  • ½ cup sour cream, at room temperature
  • 12 tablespoon unsalted butter (1 ½ sticks)
  • 2 teaspoon sea salt
  • teaspoon black pepper
  • 1 tablespoon chopped Italian parsley (optional)


  • Place the potatoes and garlic into a large stockpot and cover with salted cold water. Bring the potatoes to a gentle boil and cook for 15-20 minutes or until tender. Drain the potatoes and garlic and add back to pot or large mixing bowl.
  • While the potatoes are boiling, cook the butter in a medium saucepan over medium heat, stirring often, until it foams and has a nutty aroma, about 5-7 minutes. Remove from heat.
  • Add milk, sour cream, ¾ of the brown butter, salt and black pepper and mash potatoes. After slightly mashed, beat with an electric mixer on medium speed until smooth and fluffy.
  • Transfer the mashed potatoes to a serving dish. Top with remaining brown butter and some fresh herbs if desired.


  • Start the potatoes in cold water, add salt, bring to boil and then reduce to simmer. If you start in hot water, the potatoes will cook unevenly.
  • Drain the potatoes well to avoid a mushy, watery mess.
  • Use room temperature ingredients so they are absorbed more evenly by the potatoes.
  • If you don't have sour cream, Greek yogurt makes for a good substitute.
  • Do not overwork the potatoes. You want to mash/whip until just light and fluffy.
