These creamy slow cooker mashed potatoes are the ultimate set-it-and-forget-it side dish, perfect for holidays and potlucks. They free up your stovetop and deliver a velvety, crowd-pleasing texture every time.
Don’t skip draining the cooking liquid before mashing to avoid watery potatoes. Warm the milk and butter before adding to keep the potatoes from becoming gluey. Yukon Golds are recommended for the best texture; Russets can be used but are more prone to gumminess. The potatoes can be made a day ahead and reheated in the slow cooker on LOW with a splash of warm milk.
