Ingredients
  

  • 5 pounds gold or russet potatoes, rinsed and peeled1
  • ¾ cup chicken broth2
  • 5 cloves garlic
  • ⅓ cup unsalted butter, room temperature
  • ⅓ cup sour cream3
  • ½ cup grated onion
  • ½-1 cup milk4
  • 2 teaspoons salt
  • 1 teaspoon white pepper
  • 1 teaspoon dried parsley
  • ½ teaspoon fresh thyme, minced
  • ½ teaspoon fresh sage, minced
  • ½ teaspoon fresh rosemary, minced

Special Equipment

Instructions
 

  • In a large slow cooker (5 to 6 quart— here's the one I own and love!) add the potatoes, broth, and garlic. Cook on high for 3-4 hours or until the potatoes are very fork tender.
  • Once the potatoes are fork tender, turn the slow cooker to the warm setting. Add in the butter, sour cream, onion, and ½ cup of milk. Using a hand mixer or potato masher, whip the potatoes until they reach your desired consistency— I prefer them to be more creamy and smooth. Add in ¼ cup increments additional milk for additional creaminess.
  • Stir in the salt, white pepper, parsley, thyme, sage, and rosemary. Taste, and add more salt and pepper, if needed. Leave the slow cooker on the warm setting transfer to a serving dish for serving.

Notes

Make Ahead Instructions: If you're keeping the potatoes in the slow cooker on warm, you may need to add more milk before serving to keep the creamy and smooth texture. 
 
  1. Potatoes: Any potatoes would work in this recipe. I've used russet, golden, and red potatoes. If using golden or red potatoes, feel free to leave the skin on.
  2. Broth: I prefer to use low-sodium broth and add additional salt, as needed. To keep this vegetarian, you can use vegetable broth. 
  3. Sour Cream: You can use either sour cream or yogurt. If needing this to be dairy free, a dairy free yogurt substitute can be used.
  4. Milk: Any milk fat can be used, though the more fat % the creamier the potatoes will be. I've also used unsweetened almond milk.
