One of Ree Drummond’s favorite parts about Thanksgiving is all the leftovers—and that includes her creamy mashed potatoes! 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. Start off with quick Instant Pot mashed potatoes or something with added flavor like spicy pepper jack mashed potatoes. Then, give these fun potato recipes a try: mashed potato enchiladas, potato croquettes, and mashed potato egg casserole—it's the perfect post-Thanksgiving breakfast meal. 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. Not ready to use up all that extra mash? Don't worry, you can always freeze your mashed potatoes to make at a later date.
