  • 5 pounds (2.2 kg) potatoes peeled and cut into 1 1/2-inch pieces*
  • 1 cup chicken broth / stock
  • 4 cloves garlic crushed
  • 1/3 cup butter diced (reduced fat if counting points or calories)
  • good pinch of salt (adjust to your tastes)
  • 2/3 cup sour cream (light if counting points or calories)
  • 1/3-1/2 cup hot milk (skim or 2% if counting points or calories)
  • 1/2 cup fresh grated parmesan cheese (optional -- substitute with cheddar if your prefer)
  • pepper to taste


  • Place the potatoes, broth, garlic and butter into a 6qt slow cooker. Season with salt; mix together and cover with lid. Cook on HIGH setting for 4 hours or LOW setting for 7-8 hours, until very tender.
  • Mash potatoes with a potato masher or electric beater. Stir the sour cream and milk through until well combined and creamy (add more milk if desired). Stir through the parmesan cheese.
  • Keep on low or warm setting until ready to serve.


*You can use unpeeled potatoes if you like skin in your mash!
Slow cooker mashed potatoes maintain a creamy consistency for a couple of hours after mashing if the lid stays on the slow cooker. If the lid has been removed and the potatoes have dried out a little, just add a little more milk to reach desired consistency.
