10 Easy Ways To Make Use of Leftover Mashed Potatoes
1. Mashed Potato Pancakes
These crispy pancakes are one of my favorite ways to use up leftover mash. Feta and fresh herbs give them a Mediterranean twist. The outside turns golden and crunchy, while the inside stays creamy. They come together in about 15 minutes, so they’re perfect for a quick breakfast or side dish.
Tip: Use chilled mashed potatoes; they hold their shape much better than warm ones. Serve with a dollop of yogurt or a squeeze of lemon for extra brightness. Get the recipe →
2. Fried Mashed Potato Balls
If you want something crowd-pleasing, make these. Roll leftover mash with cheese, coat in breadcrumbs, and fry until deeply golden. The outside is shatteringly crisp. The inside stays warm and cheesy. They’re a hit as a party appetizer or a fun side for weeknight dinners.
Tip: Chill the shaped balls for 15 minutes before frying; it helps the coating stick and keeps them from falling apart in the oil. Serve with ranch or marinara for dipping. Get the recipe →
3. Leftover Mashed Potato Rolls
These dinner rolls are soft, slightly sweet, and nowhere near dense. Leftover mash goes straight into a yeasted dough, and the potato starch keeps every bite pillowy. They taste a lot like Hawaiian rolls, but you’re making them from scratch with ingredients already in your kitchen. Great for holiday leftovers, since any style of mash works here.
Tip: Don’t rush the two rises; that’s what gives the rolls their soft texture. Warm one up with butter, and you’ll understand why this one’s a keeper.
