Make Ahead Slow Cooker Mashed Potatoes

  • PrepTime: 25 Mins
  • CookTime: 3 Hrs 30 Mins
  • TotalTime: 3 Hrs 55 Mins


  1. 5 pounds russet or Yukon gold potatoes (peeled and quartered)
  2. 1 (8-ounce) package cream cheese (softened)
  3. 1 cup sour cream
  4. 1 teaspoon onion powder
  5. 1 1/2 teaspoons salt
  6. 1/4 teaspoon garlic powder
  7. 1/4 teaspoon white pepper
  8. 1 egg (beaten)
  9. 1/3 cup butter


  1. Gather the ingredients.
  2. Cook the potatoes in large pot of boiling salted water until they are tender, about 20 to 30 minutes.
  3. Drain the potatoes in a colander, return the potatoes to the dry pot. Shake over low heat for about 1 minute. This helps make the potatoes fluffy as it drives off excess moisture.
  4. Mash the potatoes until there are no lumps. Beat in the cream cheese, sour cream, onion powder, salt, pepper, and egg.
  5. Place the mashed potatoes in a greased 9 x 13 baking dish. Melt the butter and drizzle over the potatoes. Cool for 20 minutes, then cover and refrigerate up to three days.
  6. Take the potatoes out of the refrigerator about 3 1/2 hours before serving time. Stir the potato mixture well. Remove the potatoes from the dish and place it in a 4- or 5-quart crockpot. Cover and cook on low heat for 3 to 4 hours, stirring once or twice.
  7. You can add more melted butter or some cream or milk if you want a softer consistency. The potatoes can be held in the slow cooker an additional 30 minutes or more on low. Or, turn the crockpot to "keep warm" for another hour or two, if necessary.
  8. Serve and enjoy!


  1. For easier clean up, try using a liner in your slow cooker for easier cleanup.
  2. Cook entirely in the crockpot. Instead of boiling the potatoes to start in a separate pot, you can cook these potatoes from start to finish in the slow cooker. It will take longer, but, if you would prefer to "set it and forget it," this is a good option. Add your potatoes, milk for a cooking liquid (about 1 1/2 cups), put in your spices, and set on high for 4 to 5 hours. Add the butter and other dairy ingredients at the end.
  3. To make dairy-free potatoes, you can also cook the potatoes in chicken or vegetable broth instead of using sour cream, cream cheese, and butter.
