Grease your crockpot with nonstick cooking spray.
Peel and chop your potatoes into 1-inch chunks.
5 pounds russet potatoes
Add them to the crockpot with the chicken broth, salt, and pepper. Stir.
1½ cups low-sodium chicken broth, 1 teaspoon kosher salt, ½ teaspoon ground black pepper
Cover and cook on high for 4-5 hours or until the potatoes are fall-apart tender.
Add in the cream cheese and use a potato masher to mash the potatoes right in the pot.
½ cup cream cheese
Melt the butter in a pot over medium heat. Add in the milk and cream, warming until steaming.
1 cup milk, ½ cup unsalted butter, ½ cup heavy cream
Pour the milk and butter mixture into the potatoes. Gently fold the mixture until the potatoes have absorbed the liquid and are creamy.
Garnish with chives, if desired, and serve with more butter.
