Ingredients

2 pounds russet or Yukon Gold potatoes, peeled and cut into 1-inch cubes
1 pound turnips, peeled and cut into 1-inch cubes
4 tablespoons butter
1 cup whole milk or 2% milk, divided
1 teaspoon salt
½ teaspoon black pepper

Instructions

Lightly grease a 4- to 6-quart slow cooker with butter or nonstick cooking spray.
Add the cubed potatoes and turnips, spreading them into an even layer.
Pour ½ cup of the milk over the vegetables. Sprinkle with the salt and pepper, then distribute the butter pieces across the top.
Cover and cook on HIGH for 3 to 4 hours or LOW for 6 to 7 hours, until both vegetables are very tender.
Warm the remaining ½ cup of milk.
Mash the vegetables directly inside the slow cooker using a potato masher. Leave a few small pieces if you prefer a more rustic texture.
Gradually stir in the warm milk until the mash reaches your desired consistency. Add additional warm milk if a softer texture is preferred.
Taste and adjust the seasoning before serving. Add an extra pat of butter if desired.
