10 Delicious Dishes to Create With Leftover Mashed Potatoes

Next time you're mashing up a big batch of the ultimate comfort food, mashed potatoes, consider doubling the recipe. Those leftover 'taters can be used to make some seriously tasty (and sometimes surprising) dishes - from pierogi to peppermint patties, quesadillas, and waffles.

Pro tip: If you want to make mashed potatoes that are tasty re-heated the next day, plan on adding a bit of extra fat to the mix. These Day Before Mashed Potatoes are fortified with cream cheese and sour cream (along with the usual butter) to keep them extra moist and as tasty reheated as the first day they were made.

2) Potato-topped casseroles

Serve up a one-dish meal in the form of Shepherd's Pie. Veggies, meat, gravy and potatoes all in one casserole dish. Not a meat eater? Try an equally comforting plant-based version.
