Equipment
Method
- Put the potatoes, chicken broth, and salt in a 6-quart slow cooker and stir to combine.
- Cover and cook on LOW for 6 to 7 hours or HIGH for 3 to 4 hours, until the potatoes are very tender and easily pierced with a fork.
- Warm the milk in the microwave until just warm, about 45 seconds.
- Add the butter to the slow cooker.
- Mash the potatoes with a potato masher until mostly smooth.
- Stir in the warm milk, sour cream, and black pepper until creamy.
- Cover and let stand for 5 minutes before serving.
Notes
For the smoothest texture, mash while the potatoes are hot. Refrigerate leftovers for 3–4 days or freeze them; for a vegetarian version, use vegetable broth.
