Slow Cooker Mashed Potatoes are a great way to free up space on your stove. They are easy to make, can be made ahead, and full of flavor thanks to a little garlic.


  • 5 pounds (2.3kg) Yukon gold or russet potatoes, washed and scrubbed (peeled if desired)
  • 1 cup (235ml) chicken broth
  • 1 cup (235ml) whole milk or half and half
  • ¼ cup (55g) butter
  • 4-6 cloves garlic, minced
  • salt and pepper to taste
  • 1 cup (235ml) sour cream, yogurt, or 4 ounces cream cheese


  1. Place cubed potatoes in the slow cooker. (cut into 1½ inch cubes) Pour in the chicken broth and milk. Add butter and sprinkle with garlic, salt, and pepper. Be sure to leave the garlic on top so it doesn't burn.

  2. Cook on HIGH for 3-4 hours or LOW 6-8 hours or until potatoes are tender.

  3. When ready to mash add in the sour cream and mash with a potato masher or an electric mixer. Just be careful not to over mix or your potatoes may become gummy. Serve immediately or place on the warm setting for up to 2 hours. Stir before serving.

Recipe Notes

  1. If your potatoes are little dry stir in more milk. 
  2. Use russets or Yukon gold. Red skinned require more mashing to become smooth and run the risk of becoming gummy.
  3. I like to use chicken broth and it's what I have always used but feel free to replace it with vegetable broth.
  4. Do not use reduced-fat or skim milk as they curdle much easier. If you are worried about it curdling use half and half or even heavy cream. I have always used whole milk and haven't had a problem but all slow cookers cook differently.
  5. If garlic is not your thing feel free to leave it out. 
  6. Freezer Friendly- Cool completely and place in an airtight container or freezer bag. Freeze for up to 6 months. To use: thaw completely and reheat as desired. You will need to add a little more broth or milk to make them creamy again.
