This Easy Crockpot Cream Cheese Mashed Potato Casserole is the ultimate set-it-and-forget-it side dish. Cream cheese makes it ultra-creamy, and the slow cooker keeps it warm for hours—perfect for holidays and potlucks.
For best results, use room temperature cream cheese and warm the milk. Avoid over-mashing to prevent gluey texture. This casserole can be made a day ahead and reheated. For a dairy-free version, use vegan cream cheese and plant-based butter.
