Even so, making a huge batch of mashed potatoes can leave you with that age-old holiday conundrum: What should you make with all the leftover mashed potatoes? You can always eat mashed potatoes straight from the fridge, use them as a topping for shepherd's pie, or thin them out with chicken broth and simmer with sautéed leeks, thyme, and a splash of white wine for soup. Or you can make one of these delicious leftover mashed potato recipes. Remember that proper food storage is key: Always use an airtight container and keep leftovers on the highest shelf in your refrigerator. (You can store mashed potatoes for up to four days.) Then, add a bit more milk and a pat of butter to preserve their creamy texture when reheating. 01 of 20 Vegetarian Shepherd's Pie Caitlin Bensel Who says you need beef to bake an incredibly delicious Shepherd's Pie?
