Slow Cooker Buttermilk Mashed Potatoes–these are my favorite mashed potatoes. Cubed potatoes are cooked for a few hours in your slow cooker with garlic cloves and bay leaf. Then they’re mashed with butter and buttermilk for ultimate creaminess and flavor.

I would cook and then freeze.
Can your peel these ahead and freeze them? Or should you cook and then freeze?
I made these last night and thought they were great! They were gobbled up! Thanks!
I made these today for Sunday dinner but they didn't turn out as well as yours did. After less than an hour in the crock-pot I noticed the potatoes on top were turing an ugly brown–I guess because potatoes oxidize. I used the cup and a half of water and it didn't cover the potatoes up. Should I just cover the potatoes with water the next time?
