One of Ree Drummond’s favorite parts about Thanksgiving is the side dishes. "Sometimes, I even forget to put the turkey on my plate," she says. In particular, she loves a big heaping of her creamy mashed potatoes. And she feels the same about all the leftovers. After all, no one in the history of the world has ever complained about having extra mashed potatoes, especially when you worked so hard to avoid those common mashed potato mistakes.
So, now that you have your perfect mash, what will you do with the leftovers? Besides simply reheating your mashed potatoes, you can also get creative with these leftover mashed potato recipes. Whether you crisp them up into mashed potato pancakes or completely transform them into a comforting casserole, this list has tons of creative ideas to give your potatoes new life. Of course, if you want to keep things classic, you can't go wrong with homemade shepherd's pie or a sandwich made with all your holiday favorites.
But if you want to try some thing different this year, give these fun potato recipes a try: mashed potato enchiladas, fried mashed potato balls, and mashed potato egg casserole—it's the perfect post-Thanksgiving breakfast meal. You can even make bread and pillowy gnocchi for dinner! Not ready to use up all that extra mash quite yet? Don't worry, you can always freeze your mashed potatoes to make any of these leftover mashed potato recipes at a later date.
