Slow Cooker Mashed Potatoes

When you first combine the milk and potatoes, the potatoes won’t be completely covered by the liquid. The butter will eventually melt, and as the potatoes heat up they will release their own liquid, eventually covering the potatoes.

4 Serve warm: Potatoes are best if served soon after mashing them. However, you can also do this:

Hold Potatoes on "Warm": Mashed potatoes can be held on the "warm" setting of your slow cooker for up to two hours or so without noticeable loss of flavor or texture. However, note that the color does begin to deepen the longer you hold them.

Reheat Potatoes Later: Reheated mashed potatoes are always a bit tricky since the potatoes seem absorb more butter and cream. Plan on adding a little more butter and cream the next day as the potatoes warm – just eyeball it (too much cream and butter is rarely a problem!). Once warmed, whip the potatoes with a hand mixer for about 45 seconds to recreate your desired consistency.
