No ones wants to hurry up and mash potatoes minutes before a holiday dinner is served. These potatoes can be made up early and still be creamy when dinner is served.
"Each year I make this for holidays. I'm up early to put the meat in anyway, so now the mashed potatoes are ready to go, too. The slow cooker liners are perfect. Any leftovers, I just let out the air and twist tie it before putting in the fridge. No dishes."
