"When it comes to holiday dinners, the more dishesyoucan make ahead, the better, right?Mashed potatoes are central to our holiday meals (how else can you make gravy volcanos?) and they are the easiest thing in the world to make ahead. Stress-free! (At least the potato part.) In this simple recipe we are are mashing boiled potatoes and garlic (a potato ricer is helpful for making everything fluffy), mixing them with butter, cream cheese, yogurt, and a touch ofrosemary. The cream cheese helps fortify the mashed potatoes so they reheat well, and the yogurt gives them a light tang. You couldalso use sour cream. Heapthe baking dish with the potatoes, and chill untila couple hours before dinner time, then let come to room temp and bake. Easy!..."
