  • 10 medium Potaotes, cut into 1" cubes
  • 1 Cup Sour Cream
  • 1/2 Cup Milk
  • 1/4 Cup Butter
  • 2 tsp Onion Powder
  • 2 tsp Garlic Powder
  • 1 tsp Salt


  • Peel your potatoes.  Plan on 1.5 medium potatoes per person.  I have a family of 7 so I usually do 10 potatoes.
  • Place the potatoes in the crockpot and cover the potatoes with hot water.  Add 1 tsp of salt.  Cover with lip and cook on high for 2.5-3 hours, depending on how hot your crockpot cooks.
  • The potatoes will be done when you poke them with a fork and the potato doesn't lift when you pull the fork out.
  • Drain the water from your potatoes.  I just use a dish towel to handle the hot crockpot and offset the lid a little to work as a strainer. It's okay if you don't get all the water out. I couple tablespoons of remaining water is fine.
  • Add the sour cream, half of the milk, butter, onion salt, garlic powder, and half of the salt. Use a potato masher to mash the potatoes.  (Do not over mash or the potatoes will develop a gluey texture.)
  • Taste the potatoes.  Add the remaining milk and salt if desired.  
  • Serve with gravy or load them up with ranch dressing, bacon and green onions. Enjoy!
