  • 3 pounds Russet potatoes (unpeeled) , cut into quarters
  • 1/2 teaspoon fine sea salt , plus more to taste
  • 1/4 teaspoon freshly cracked black pepper , plus more to taste
  • 1/2 teaspoon dried oregano
  • 4 cloves chopped roasted garlic
  • 2 tablespoons unsalted butter
  • 1/4 cup plain Greek or Skyre yogurt full fat or 2% work better
  • 1 - 2 tablespoons milk , (I used almond milk) or more as needed
  • grated Parmesan for topping optional
  • chopped parsley for topping optional


  1. Cut your potatoes into quarters and place them in the slow cooker along with the salt, pepper, oregano and roasted garlic.

  2. Cook for 2-3 hours on high or 5-6 hours on low, or until potatoes are tender. (Mine usually take about 2.5 hours)
  3. Once potatoes are tender, add the butter and mash with a potato masher until fluffy. Add sour cream and milk and continue mashing until smooth.

  4. Adjust seasonings as needed. Serve warm with more butter, grated Parmesan, and chopped parsley if desired.
