My secret to the best mashed potatoes is adding cream cheese and using my hand mixer for even and fast mixing. The texture becomes both light and airy as well as creamy at the same time. My husband has now deemed these our official holiday mashed potatoes! Serve them alongside Turkey Tenderloin or Honey Glazed Ham.

  • Head of garlic: The key for the best flavor is to roast it until fully tender and the garlic will become both savory and a little bit sweet.
  • Olive oil: Cooking oil for the recipe.  
  • Cubed Russet or Yukon Gold potatoes: Peeling these is best. Use russet for a starchier texture and Yukon gold for a creamier texture.
  • Cream cheese or sour cream, regular or 1/3-less fat: Any of the three work nicely depending on how you like your mashed potatoes. I’ve even used a combination of cream cheese and sour cream.
  • Butter: Adds nice richness and fat to round out the flavors.
  • Heavy whipping cream: Always start with 1/4 cup and add more as desired to make them as creamy as you’d like.
  • Salt: Season to taste.

expert Tips

  • Always start the potatoes from cold water. This will be the best method for even cooking of the potatoes until they are tender.
  • Use a hand mixer for whipping ease. It mixes the potatoes in seconds and makes them extra creamy! Or you can use a potato masher or ricer.
  • Always add more salt or cream if you desire. You can make these potatoes as creamy as you’d like!
  • Make sure you fully roast the garlic through. It should be lightly caramelized and very tender to pierce with the tip of a paring knife.
  • Drain the potatoes well after boiling. If you find your potatoes thin or watery in texture, this is probably why.
  • Avoid mixing the potatoes too much. They will become dense and gluey in texture if you do.
