Creamy, rich, and infused with mellow garlic, these slow cooker mashed potatoes are the ultimate make-ahead side dish for holidays and cozy dinners. The slow cooker does all the work, delivering velvety texture and deep flavor with minimal effort.
For the best texture, use Yukon Gold potatoes and do not skip rinsing the cut potatoes. Keep garlic cloves whole to avoid bitterness. Warm the dairy before adding to prevent gumminess. Do not overmix. To make ahead, cook completely, cool, and refrigerate overnight; reheat on LOW with a splash of warm milk or cream. For a dairy-free version, use vegan butter and unsweetened oat milk or full-fat coconut milk.
