Make-Ahead Mashed Potatoes

By , from the Culinate Kitchen collection


My mother gave me this recipe; her mother-in-law gave it to her. Their version contains 2 teaspoons of garlic salt, but I’ve tinkered with it, adding roasted garlic instead. Because you make it the day before you serve it (and reheat it before eating), it’s a good bet for busy holiday dinners. In fact, you can keep it covered and chilled for up to three days before baking it.


5 lb. russet potatoes (8 large potatoes)
1 cup sour cream
8 oz. cream cheese, softened
2 tsp. salt
~ Pepper, to taste
7 garlic cloves, roasted (see Note, below)
4 Tbsp. butter
~ Sweet paprika (not hot or smoked)


  1. Peel and cube the potatoes. Boil in salted water until soft; drain well.
  2. Place the potatoes in a deep mixing bowl. Add the sour cream, cream cheese, salt, pepper, and garlic cloves. Using an electric mixer, blend all ingredients until smooth.
  3. Turn mashed potatoes out into a 13-by-9-inch metal or Pyrex baking pan. Dot with the butter and sprinkle with a bit of paprika for color. Cover with foil and refrigerate overnight or for at least 12 hours.
  4. An hour or so before serving, remove the potatoes from the refrigerator and preheat the oven to 400 degrees. When the oven is hot, warm the potatoes for about an hour, until hot throughout. Serve immediately.


About roasted garlic. If you don’t have any roasted garlic on hand, do this: Cut the top off a head of garlic (not the root end) to expose the cloves, then wrap it in foil; or you can place unpeeled garlic cloves in a small, ovenproof dish. Cook in a preheated 375-degree oven until soft and pulpy, about 20 to 30 minutes. If you cooked the whole head, wait until it’s cool, then squeeze out just the garlic you need; whole cloves can go right in.

My mother used to make these (and still does) for big family gatherings and any other time she needed to get things done ahead of time. I love how they are baked so that there are little crispy bits around the edges of the pan.
A word of warning : these potatoes can get extremely hot and keep their heat well on the way to the table. We have had several instances where mouths have been burned and have learned to warn guests about it. However there is always the issue of them being so good everyone wants to dip a fork in as soon as it hits the plate!
