Before you even think about using leftover mashed potatoes, you need to produce the leftovers first. If you have leftover mashed potatoes, transfer the rest to a clean box or container. If you want to cook with it the next day, you can leave the rest covered overnight. If you only want to use the leftovers in the next few days, the leftover porridge should be chilled, especially if you worked with fresh milk or butter.

We’ve rounded up our 7 favorite tips for you on how to use up leftover mashed potatoes. In your refrigerator or pantry, you will surely find ingredients that you can use to develop your ideas in creative ways. Mashed potatoes are more versatile than you think!


  • casserole filling

Here you can use several leftovers at once: you can easily cover leftover meat, fish or vegetables with the remaining mashed potatoes and bake them in the oven. At 200°C, the pan turns golden yellow after 20 minutes. If you want the casserole to be particularly attractive, you can pour the puree over the casserole in waves through a cut freezer bag.

Tip: add cheese to leftover mashed potatoes, this makes the filling even spicier!

  • Duchess potatoes

This classic French side dish is mashed potatoes with a noble name! All you need is the remaining puree, spices and herbs, and a bit of butter. Twisted Potato Drops are traditionally fried in butter, but you can also let them sit in the oven. In our recipe for classic duchess potatoes, we show you step by step how to prepare this delicious side dish.

  • base for sauces

Leftover instant mashed potatoes in particular are often no longer visually appealing. It doesn’t matter if you mix the leftovers into a thick, creamy sauce or use them as a base for cream sauces. Potato starch binds sauces well.


  • Cakes, Muffins, Cookies

Cold mashed potatoes are a great ingredient for muffins, bread, or cake batters. Do you have whole wheat dough that feels too dry? Then add a little mashed potato: this makes the dough moister and particularly strong flours develop their aroma better.

  • Potato soup

Here you save double! If you have mashed potatoes left over, you can use it to replace up to 50% of the amount of potatoes in most soup recipes. It saves you time on peeling and you can cook a creamy soup with just a few potatoes. You can find out how to do it step by step in our mashed potato recipe!

  • Balls with a bite

When using leftovers, mix not only mashed potatoes, but also nuts, sunflower seeds, or seeds to form a firm dough. You can add grated cheese and breadcrumbs for a better union. Season the dough however you like, perhaps exotic with curry and ginger or traditional with Mediterranean herbs. Roll the dough into balls and bake in oil for a crispy snack or delicious side dish.

These ideas can be expanded and refined with many ingredients. For example, with different types of cheese or smoked fish, chopped ham or dried tomatoes – with a little imagination you can use almost anything with mashed potatoes!
