Mashed potatoes are the ultimate comfort food and a versatile side dish. The mild flavor pairs well with most meats, fish, vegetables, and is ideal topped with gravy.
Make Ahead Mashed Potatoes: Mashed potatoes can be made up to 48 hours in advance. Follow the recipe, cool completely, cover, and refrigerate. To Reheat: Place the mashed potatoes in a covered casserole dish, and heat in the oven until hot, about 30 minutes. Stir in a little warm milk, if the potatoes are dry.
