  • 2 pounds firm-fleshed potatoes
  • 1 ½ cups milk
  • 1 cup heavy cream
  • Pinch nutmeg
  • 1 teaspoon Dijon mustard
  • 1 teaspoon kosher salt
  • 1 clove garlic
  • 1 tablespoon soft butter
  • Chopped parsley or dill (optional)


  • Peel the potatoes and cut them into ⅛-inch-thick slices. Place them in a pot with the milk, cream, nutmeg, mustard, and salt and simmer for 10 minutes.
  • Meanwhile, preheat the oven to 400 degrees F. Cut the clove of garlic in half and rub the cut sides around the inside of a baking dish (about 3 quarts is a good size since the milk bubbles up quite a bit when baking), then smear the butter around the inside of the dish.
  • Pour the potato and cream mixture into the dish and spread the potatoes out evenly. Bake for 35 to 40 minutes or until golden and bubbling. Serve hot, topped with a sprinkling of chopped parsley, if desired.


  • This recipe uses kosher salt (aka cooking salt, kitchen salt, coarse salt outside of the US). If you are using table salt, definitely scale down the salt as that is a saltier type of salt! The type of salt will make a big difference in how salty your food tastes, so keep that in mind.
