Plus, you can keep make ahead mashed potatoes warm in the crock pot all day long.

What are the best potatoes for mashed potatoes?

One of the secrets to the best mashed potatoes is choosing the right kind of potato.

For the best mashed potatoes, choose higher starch potatoes, like Russets or Yukon golds. They make the fluffiest, smoothest, and most flavorful mashed potatoes.

Waxy potatoes (such as new, red, or white varieties) require more mashing to become creamy, which could result in gluey, pasty spuds. Save these for another recipe.

How to Make Ahead Mashed Potatoes without cream cheese:

Here are some ideas for ultra-creamy mashed potatoes that doesn't require cream cheese:

  • Heavy cream. Whipping cream makes an excellent stand in for cream cheese.
  • Crème fraiche. This luxe ingredient is easier to find than ever and adds a delightful tanginess to everything it touches.
  • Neufchatel. A soft cheese with a French origin. It melts into hot potatoes like a dream.
  • Ricotta cheese. Soft, pillowy ricotta makes an excellent cream cheese substitute.

  • Truffled Mashed Potatoes: If you have some, drizzle white truffle oil over the potatoes instead of (or in addition to) melted butter!

    This is basically how I make mine plus I add some buttermilk also and they are super flavorful. But I never tried using egg whites. I shall this thanksgiving to see how there are the next day upon reheating.5 stars

    Why do you have to use reduced-fat cream cheese and sour cream? Can’t you use full fat versions?5 stars

    1. meggan

      Hi Lynn, honestly that’s a complete mistake! I would personally never buy reduced-fat anything, I don’t cook with it, it doesn’t belong in my kitchen. So I’m not sure how that happened. You should use full-fat versions, there is no issue with it, and it will be superior. I’ll be fixing the post! Thanks and sorry about that. -Meggan
