This crockpot cream cheese mashed potato casserole is a velvety, rich side dish that’s perfect for holidays or weeknight comfort food. Parboiled potatoes are mashed with cream cheese, butter, and sour cream, then slow-cooked to creamy perfection.
Do not skip parboiling the potatoes; raw potatoes in a slow cooker become mealy. Warm the milk to prevent gluey potatoes. Avoid lifting the lid during cooking. For make-ahead, prepare through step 6, refrigerate overnight, then cook on low for 3-4 hours. Leftovers keep in the refrigerator for up to 4 days or freeze for up to 3 months.
