Cheesy Garlic Slow Cooker Mashed Potatoes

  • Author: Aberdeen
  • Prep Time: 5 minutes
  • Cook Time: 4 hours
  • Total Time: 4 hours 5 minutes


  • 3 lbs red potatoes, diced (no need to peel!)
  • 1 1/2 cups milk + extra as needed
  • 2-3 garlic cloves, minced
  • 1/2 cup unsalted butter
  • 1/4 cup sour cream
  • 1 cup cheddar cheese
  • 1/2 cup parmesan cheese
  • Salt and pepper to taste
  • 1 tablespoon fresh chives, minced


  1. Turn on and grease the inside of the slow cooker with a little bit of the butter. Add potatoes, milk and garlic to the slow cooker. Cook for 3 1/2 to 4 hours on high, or 7-8 on low.
  2. Mash the potatoes right in the slower cooker. Add the butter and sour cream, mash to combine.
  3. Stir in cheeses until completely mixed.
  4. Add more milk if necessary to reach desired consistency.
  5. Add salt and pepper to taste. Keep slow cooker on warm and with lid on until ready to serve. Top with fresh chives, fresh ground black pepper, and, of course, a little more butter!


*There may be some browned milk on the sides of your slow cooker when its finished. It's actually quite tasty and just changes color. I actually mix it into the mashed potatoes but feel free to just scrape it off and discard it if desired.

I use a 5 quart slow cooker. If using a smaller slow cooker, this recipe can easily be halved!
