Ingredients

  • 3 pounds red potatoes peeled and cut into 1" cubes
  • 2 teaspoons salt (divided)
  • 1 cup sour cream
  • 1/2 cup milk (divided)
  • 1/4 cup butter
  • 2 teaspoons onion powder
  • 2 teaspoons garlic powder

Instructions

  • Place the potatoes and salt in the crockpot and cover with hot water.  Add half of the salt, then cover and cook on high for 2½-3 hours.
  • Once your potatoes are cooked through, pour the potatoes and water through a strainer in the sink to drain the cooking water. Return the potatoes to the crockpot and add the sour cream, half of the milk, butter, onion powder, garlic powder, and the other half of the salt. Use a potato masher to mash the potatoes, but do not over mash or the potatoes will develop a gluey texture.
  • Taste the potatoes, and add the remaining milk and more salt if desired.
  • Serve warm and enjoy!

Notes

For a little extra flavor in your mashed potatoes, add 1/2 cup grated Parmesan cheese. 
Storing leftovers: store in an airtight container in the fridge for up to 4 days, or in the freezer for up to 3 months.
Reheating: to reheat in a slow cooker, warm on low for 3-4 hours, stirring a couple of times throughout. Add a bit more milk (or heavy cream) and a few tablespoons of butter towards the end of the warming time.
