Tips for Making Slow Cooker Mashed Potatoes

  • I love the texture of skins in my mashed potatoes, but if you don’t like that, feel free to peel the potatoes.
  • The water and chicken broth don’t need to cover the potatoes in the slow cooker. The steam from the crockpot will help them soften up.
  • Reserve a little of the cooking liquid in a small bowl if you need to thin the potatoes a bit after mashing. You can also use milk or Greek yogurt for this purpose.
  • For chunkier mashed potatoes, use a potato masher. For creamier mashed potatoes, use an electric hand mixer.
