  • 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
  1. Peel your potatoes.  Plan on 1.5 medium potatoes per person.  I have a family of 7 so I usually do 10 potatoes.

  2. 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.

  3. The potatoes will be done when you poke them with a fork and the potato doesn't lift when you pull the fork out.

  4. 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.

  5. 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.)

  6. Taste the potatoes.  Add the remaining milk and salt if desired.  

  7. Serve with gravy or load them up with ranch dressing, bacon and green onions. Enjoy!
