Ingredients

To Cook the Potatoes

  • 5 pounds Potatoes (peeled if desired and cubed)
  • Water (just enough to cover the potatoes)
  • 2 teaspoons Chicken Bouillon Powder or 2 bouillon cubes (check the package for equivalent strength)
  • 2 cloves Garlic (Or to taste. Peeled and left whole, optional)
  • 2 teaspoons Salt

To Finish

  • 1 cup Butter softened (2 sticks)
  • ½–1 cup Whole Milk or Heavy Cream or Half and Half (plus more if needed for holding)
  • ½ cup Sour Cream
  • Salt, to taste
  • Black Pepper, to taste

Instructions

Prep

  • Scrub the potatoes. Peel them, or leave the peels on if desired. Cut into similar-sized cubes.

Slow Cook the Potatoes

  • Add the potatoes to the slow cooker and pour in just enough water to cover them. Add the chicken bouillon, garlic if using, and 2 teaspoons salt.
  • Cover and cook on High for approximately 4–5 hours, until the potatoes are tender and mash easily with a fork, with no firm centers.
  • Turn off the slow cooker. Carefully drain the potatoes in a colander, keeping the garlic with them, then return the potatoes and garlic to the slow cooker.

Make the Mashed Potatoes

  • Add the softened butter and partially mash the potatoes with a potato masher.
  • Gradually add the milk, starting with ½ cup, and continue adding milk while mashing until the potatoes reach your desired consistency. You may not need the full cup.
  • Stir in the sour cream.
  • Taste and add salt and pepper as needed. Stir gently to combine.

Serve or Keep Warm

  • Serve immediately, or cover and turn the slow cooker to Warm. Keep the potatoes at 140°F or above until serving.
  • Stir occasionally and replace the lid. If the potatoes become too thick, gently stir in a little more milk.

Notes

Slow Cooker Size:
I use a 6-quart slow cooker, and this batch just fits in mine. Use a larger slow cooker if needed to stay within your model’s recommended fill level.
Cream Cheese:
If desired, start with 4 ounces of softened, cubed cream cheese, adding it with the butter. Mash until incorporated, then taste and add up to 4 more ounces if desired.
